Problems solved by technology

[0004]1. Traditional anti-corrosion paints are mostly solvent-based, and construction in summer is easy to cause damage to workers' bodies and is not friendly to the environment.
[0005]2. The traditional anti-corrosion paint is separated from the bottom and the surface, secondary construction type, low labor efficiency.
[0008]The paint film is not strong and easy to fall off

Abstract

Provided is organosilicone modified heat-resistant self-cleaning waterborne electrochemistry corrosion-resistant paint. The raw material comprises a resin emulsion. The organosilicone modified heat-resistant self-cleaning waterborne electrochemistry corrosion-resistant paint is characterized in that the resin emulsion is an MPM modified acrylic acid resin microemulsion, the raw material further comprises a coupling agent gamma-methacrylonitrile acyloxy trimethoxy silane, and the adding proportion of the coupling agent gamma-methacrylonitrile acyloxy trimethoxy silane is 0.5-3% of the raw material by mass. The organosilicone modified heat-resistant self-cleaning waterborne electrochemistry corrosion-resistant paint has the advantages that the organosilicone modified heat-resistant self-cleaning waterborne electrochemistry corrosion-resistant paint has perfect waterborne rusted, rust conversion and antirust characteristics; high hiding rate is integrated with high glossiness; weather resistance is high, and for example the products are acid-resisting, alkali-resisting, radiation-resistant and high-low temperature resistant; water repellency and a self-cleaning function are superstrong; the paint film is good in hardness, and the hardness is more than 2H; and organic solvents do not exist, volatile organic compounds (VOC) are low, and environmental protection is benefited.

Description

technical field [0001] The invention relates to the field of anticorrosion paint preparation. technical background [0002] With the development of human society, the use of metals has been ubiquitous in the fields of people's production and life. For a long time, people's protection of metals has also been accompanied by development and utilization. However, due to the limitations of resin technology and other material technologies in the past, metal protection Due to the poor comprehensive weather resistance of the coating, the protection of the metal lags behind the utilization of the metal, and a large amount of metal is corroded in a silent place. [0003] Oxidation reactions between metals, water and oxygen, and chemically corrosive substances such as acids, alkalis, salts, etc., under the action of electrochemistry, the electrons of the metals are lost and become loose and water-absorbing oxides or other salts, thereby Corrodes metals rapidly. According to data, abo...
