Coating classification: coating additive thickener

It is suggested that the thickener is a kind of rheological assistant, which can not only make the coating thickened, but also give the coating excellent mechanical and physical chemical stability, and play a role in controlling the rheological property in the coating construction Thickener can be divided into inorganic thickener and organic thickener In the aspect of inorganic thickener, nanotechnology realizes the nanometer of inorganic particles and endows inorganic thickener with some new properties; in the aspect of organic thickener, the development of polymer thickener is still the main development direction, although the polymer type is mainly polyurethane and polycarboxylate Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: thickener is a kind of rheological assistant After adding thickener, it can not only make the coating thickened, but also give excellent mechanical and physical chemical stability to the coating, which plays a role in controlling the rheological property in the coating construction Thickener can be divided into inorganic thickener and organic thickener In the aspect of inorganic thickener, nanotechnology realizes the nanometer of inorganic particles and endows inorganic thickener with some new properties; in the aspect of organic thickener, the development of polymer thickener is still the main development direction, although the polymer type is mainly polyurethane and polycarboxylate, However, by adding some substances for copolymerization, grafting some hydrophobic groups and other methods, the thickening performance is improved, but also has a certain water resistance In addition, in order to meet the requirements of low VOC, solvent-free thickener has gradually become the focus of attention Because a thickener can improve the viscosity of the system at a certain shear rate, but not at other shear rates, it is very important to study the compounding and synergism of thickeners In recent years, the main development direction of thickener is to develop polycarboxylate products, and to improve the application performance of polyacrylic acid thickener, such as storage stability, dielectric resistance and thickening ability, is an important research content at present, such as adding some substances for copolymerization modification, compounding with other thickeners, etc In addition to polycarboxylate, semi synthetic thickeners and polyurethane thickeners with good properties have been developed A lot of thickeners have been developed in China, but most of them are anionic, few of them are non-ionic, and none of them are cationic At present, the most widely used thickeners are hydration type, but the use of associated thickeners is also increasing These products are mainly polyurethanes and polyethers, and their molecular chains can be associated with emulsion particles and pigments and fillers When the shear force is applied, the associated structure is destroyed, so that the coating is easy to construct Once the shear force is removed, the pigment, filler and emulsion particles are re united through thickening agent, and the viscosity is restored, so that the coating system can be kept stable Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
