"King of Paint" raw lacquer is back

It is understood that as early as the 1950s, the Chinese Academy of Sciences carried out research on the structure and drying mechanism of raw lacquer, developed modified products of raw lacquer, and expanded the use of raw lacquer.

According to Zhang Feilong, biomass conversion technology, organic chemical reaction technology, and metal chelation technology can give it many new functions and derive many new practical products, especially urushiol titanium, urushiol silicon, urushiol phosphorus, etc.
The products play a special role in the field of industrial heavy anti-corrosion, and can be used in military industry, aerospace, petrochemical, ore machinery, power facilities, textile machinery, seawater desalination, ships, ships, marine equipment, and light industry.
For example, heavy anti-corrosion equipment such as oil extraction, oil pipelines, oil tanks, drilling, desulfurization devices, heat exchangers, etc.
; electronic component protection materials, preparation of ion selective electrodes, conductive paints for printed circuit boards, etc.
; reforms in the shipbuilding industry Sexual lacquer is used to protect the hull of ships.
Due to its unique molecular structure, it can kill or disperse sea creatures and resist the attachment of sea creatures.

The reporter learned that in recent years, Xi’an Raw Lacquer Coating Research Institute, Tianjin Zhonghai Science and Technology Industrial Corporation, Wuhan National Paint Co.
, Ltd.
etc.
have carried out technical research on raw lacquer modification, continuously expanding the application field of raw lacquer, and developed silicone urushiol and silicone heat-resistant New products such as paint, high-temperature heavy-duty anti-corrosion paint, urushiol titanium, etc.
, are widely used in oil and gas pipelines, petroleum storage tanks, heat exchange equipment, sewage treatment equipment and other special anti-corrosion coatings on the inner and outer walls of petroleum exploration, petrochemical and marine industries.
The post effect is better than ordinary paint coatings.
Recently, the School of Materials Science and Engineering of Fujian Normal University and the Key Laboratory of Polymer Materials of Fujian Province are studying the melamine formaldehyde resin/polyurushiol composite material.
The test results show that the composite material has excellent physical and mechanical properties, solvent resistance, and easy Processability and thermal stability.

"The modified derivative of raw lacquer mainly solves the problem of heat exchange and internal protection of heat transfer equipment in the petrochemical industry.
Although there are many researches on the modification of raw lacquer, it is still less used in the industrialized field, and the price is very expensive.
It is difficult for enterprises to bear, and there are only a few domestic companies.
Enterprises are doing it.
" Huang Xin, director of the Anticorrosion and Water Treatment Center of Tianjin Seawater Desalination and Comprehensive Utilization Research Institute of State Oceanic Administration, and general manager of Tianjin Zhonghai Science and Technology Industrial Corporation, told reporters that they successfully developed urushiol titanium chelate through lacquer polymerization modification.
It has the characteristics of high temperature resistance and chemical resistance.
After the application of heat exchange equipment in petrochemical enterprises, the effect is obvious, which is better than ordinary paint and coatings.
The current annual output reaches more than 100 tons, and the application range is gradually expanded.
The product consumption per ton is 600~700 Kilograms of raw lacquer.

Zhang Feilong introduced that in recent years, Xi’an Raw Lacquer Coating Research Institute has successively undertaken scientific research projects such as the National Science and Technology Support Program, the National Spark Program, the Compass Program of the Central Propaganda Department, and the transformation of agricultural science and technology, as well as special social welfare research projects, involving raw lacquer refining technology and urushiol.
There are more than 20 key technologies including the industrial development of modified coatings, the research on key technologies for the industrialization of lacquer wax refining and processing, the development of urushiol bio-based functional materials, and the research on the protection of Chinese lacquer cultural heritage.
Among them, 8 have passed the appraisal of scientific and technological achievements, 4 invention patents have been authorized by the state, and more than 20 national, provincial and ministerial awards have been obtained.
