Coating knowledge: application of rare earth in coating industry

It is suggested that rare earth elements can be widely used in rare earth coatings because of their special chemical activity At present, the application of rare earth in coating industry can be mainly summarized as drying agent, rare earth curing agent, rare earth pigment, rare earth thermal insulation coating, etc 1 In the paint industry, the traditional driers are usually organic acid soaps of cobalt, manganese, lead, zinc, calcium and other metals Although they still play an important role in coatings, there are some defects such as single drying effect, serious pollution and high price Compared with traditional driers, rare earth driers can make up for the shortcomings of traditional driers and give full play to their own Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: rare earth elements can be widely used in rare earth coatings due to their special chemical activity At present, the application of rare earth in coating industry can be mainly summarized as drying agent, rare earth curing agent, rare earth pigment, rare earth thermal insulation coating, etc 1 In the paint industry, the traditional driers are usually organic acid soaps of cobalt, manganese, lead, zinc, calcium and other metals Although they still play an important role in coatings, there are some defects such as single drying effect, serious pollution and high price Compared with traditional driers, rare earth driers can make up for the shortcomings of traditional driers and give full play to their excellent characteristics Rare earth driers can improve the color of coatings, improve the crosslinking degree, hardness and solvent resistance of coatings, eliminate the pollution of lead and calcium, and overcome the defects of cobalt driers, such as coating crusting and wrinkle The price is cheap In particular, China is short of cobalt resources and rich in rare earth resources In the 1950s, there were rare earth desiccant products on the market in foreign countries, whose main components were cerium and zirconium Since the 1980s, a series of rare earth paint driers have been developed in China, which have been successfully used in five categories and dozens of varieties of paint production Rare earth driers usually use rare earth fatty acids and rare earth naphthenic acid complexes as raw materials They can partly or even completely replace the lead, manganese, zinc, calcium and other components in the traditional drier, and can significantly reduce the amount of cobalt They can not only produce low lead or lead-free paint, but also simplify the production process The paint produced is light in color, strong in adhesion, bright and dry in film, and the quality of paint is obviously improved 2 RPO4 and R2 (SO4) 3, two kinds of rare earth salts, can be used as new high-efficient curing agents for building coatings, especially for the inorganic compound series of water glass (sodium silicate) building coatings In addition, they can also make the color of the coating soft, improve the transparency of the paint film, and greatly improve the mechanical properties and weather resistance This is because the coating treated with rare earth salt curing agent can form a huge network molecular structure 3 The traditional luminescent pigments of rare earth light storing self luminescent pigments are usually made of zinc, calcium, barium or strontium sulfide, a small amount of flux (such as sodium chloride) and a small amount of activator (such as copper chloride) mixed and calcined In recent years, it has been found that rare earth luminescent pigment has many advantages, its luminescent brightness is higher than that of traditional luminescent pigment, and its afterglow time is ten times longer, especially in China, rare earth resources are abundant and cheap, which brings favorable conditions for its research The rare earth light storing self luminous pigment developed in China is a kind of light storing luminous pigment It uses 5d-4f electron transition principle in specific rare earth elements to store energy by absorbing natural light, light, ultraviolet light, etc., and release energy in the form of visible light in the dark or at night, so as to realize the infinite repetition of light absorbing and luminous process In the molecular composition, based on the activation of EU by the original rare earth elements, and from the perspective of sensitization and coordination, the auxiliary activator is added to form the trap energy level, so that the luminescent brightness of the material is higher and the afterglow time is longer Moreover, it can be used as an additive, evenly distributed in various transparent media to realize the self luminous function of the media, and can show the bright color of the pigment, showing good low-level emergency lighting, indicating signs and decorative and beautifying effects The pigment itself is non-toxic, harmless, free of any radioactive elements, and has excellent stability and weather resistance The process of light absorption and luminescence can be repeated indefinitely The luminous products made of this kind of pigment can automatically glow in the dark place, showing good low brightness, indicating signs and decorative and beautifying effects, which can be used to make coatings, inks, plastics, Rubbers, etc., and can also be absolutely safe applied to daily consumer goods, such as clothing, stationery, toys, watches, switches, signs, decorations, handicrafts, sporting goods 4 Rare earth thermal insulation coating is the latest thermal insulation coating after traditional thermal insulation materials Rare earth thermal insulation coating is made of mineral and inorganic materials, with a variety of additives and a small amount of rare earth elements, without organic binder It integrates heat preservation, heat insulation, water-proof and anti-corrosion It has the advantages of low thermal conductivity, strong adhesion, small use thickness, simple construction, etc In addition, composite metal oxide silver, zinc and copper nano antibacterial agents are mainly added to the base material, alumina, calcium oxide and zinc oxide nano particles with far-infrared radiation characteristics are added to the filler, and titanium dioxide and rare earth activator zinc oxide are creatively added to the curing agent, so that the coating has low-cost and high-performance coating characteristics, At the same time, it has long-lasting antibacterial and bactericidal functions, with the bactericidal rate reaching 100% in 6 hours and air purification Function: eliminate harmful gases such as VOC and formaldehyde, and produce negative oxygen ions to promote human health for a long time It is to realize the indoor and outdoor air quality and strong biological climate regulation function of the ecological residence, meet the comfortable environment for people's life, and form a virtuous cycle of ecological residence system among people, buildings and ecological environment 6 Nano green toughened paint is made of rare earth modified nano TiO2 photocatalyst, adhesive, curing agent and filler It has the properties of non-toxic, tasteless, disinfecting, bactericidal, degradable harmful substances, non pollution, stable performance, long storage period, high hardness, scrub resistance and collision resistance Nano green toughened paint has the advantages of superior performance, low cost, convenient for industrial production, and no pollution to the environment in the process of production and construction It is a green product, with good economic and social benefits China is rich in rare earth resources, and its development and application prospects are broad Rare earth is more and more widely used in coating industry [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband
