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

Anticorrosion chalking paint

Technical field

The present invention relates to chalking paint, especially anticorrosion chalking paint.

Background technology

The integrated level required along with electronic equipment is more and more higher, increasing electronic product adopts encapsulating structure, and adopt chalking paint packaging electronic parts, can the globality of strengthening electronic device, improve the resistibility to external shock, vibrations, improve the insulativity between inner member, circuit, be conducive to device miniaturization, lightweight, avoid element, circuit to be directly exposed in environment, improve the waterproof of device, humidity resistance.

Existing anticorrosion chalking paint can produce contraction and exothermic phenomenon when being solidified into elastomerics, easily cause the damage of electronic devices and components.

Summary of the invention

For solving the problem, the invention provides a kind of anticorrosion chalking paint that can not produce contraction and heat release, concrete technical scheme is:
