Abstract

The invention discloses a protective coating, which comprises the following components in parts by weight: 30-45 parts of varnish, 40-55 parts of solvent naphtha, 5-8 parts of wax powder, 3-5 parts of silicon powder, and 8 parts of curing agent -12 parts, 5-8 parts of silicone additives, 3-5 parts of silicone oil; the protective coating of the present invention, silicone soft elastic coating material, can release pressure well, high temperature resistance, easy repair, wear-resistant The resistance reaches 6500-7500 or more, and it has superior insulation, super anti-ultraviolet, anti-fouling and wear-resistant, impermeability, strong moisture-proof, anti-leakage, shock-proof, dust-proof, anti-corrosion, anti-aging, and corona resistance. It can be used not only on the surface of printed circuit boards, but also on building materials, metal surfaces, wood surfaces and the surfaces of objects that need protection. The preparation method of the present invention can prepare the protective coating with good effect by using normal temperature.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a protective coating and a preparation method thereof. Background technique [0002] Under realistic conditions, such as chemical environment, vibration, high dust, salt spray, humidity and high temperature, etc., building materials, metal surfaces, wood surfaces, circuit boards and the surfaces of objects that need protection may be corroded, softened, deformed, moldy, etc. Changes and other problems, resulting in reduced service life. The chemical environment mainly refers to fuels and coolants. [0003] For example, the circuit board and its related equipment will fail in order to avoid the erosion of the environment. If the protective coating is applied to the surface of the circuit board to form a special protective film, it can protect the circuit from damage under the above-mentioned harsh conditions. damaged. The protective coating improves and prolongs the service life of the ...
