Anticorrosive self-cleaning paint

Abstract

The invention relates to a self-cleaning paint, particularly an anticorrosive self-cleaning paint. The anticorrosive self-cleaning paint is prepared from the following raw materials in parts by weight: 20-30 parts of tetramethyldivinyl disiloxane, 25-40 parts of methylethoxy silicon oil, 10-15 parts of hydroxy hydrogenous silicon oil, 15-20 parts of chlorotoluene, 1-5 parts of ethanedioic acid, 0.1-0.5 part of cyclopentanol and 0.3-0.7 part of catalyst. The anticorrosive self-cleaning paint can not generate shrinkage or release heat, and has the advantages of moderate hardness, favorable thermal conductivity, favorable electric insulativity and high sealability.

Description

technical field [0001] The invention relates to self-cleaning coatings, especially anti-corrosion self-cleaning coatings. Background technique [0002] With the increasingly high integration requirements of electronic equipment products, more and more electronic products adopt packaging structure, and the use of self-cleaning coatings to encapsulate electronic components can strengthen the integrity of electronic devices and improve the resistance to external shocks and vibrations. Resistance, improving the insulation between internal components and circuits, is conducive to the miniaturization and weight reduction of devices, avoiding direct exposure of components and circuits to the environment, and improving the waterproof and moisture-proof performance of devices. [0003] The existing anti-corrosion self-cleaning coatings will produce shrinkage and exothermic phenomena when they are cured into elastomers, which may easily cause damage to electronic components.
