Description

A kind of coating with effectiveness

Technical field

The present invention relates to a kind of coating with effectiveness.

Background technology

Along with the develop rapidly of information technology, computer network, information processing device, electronic communication equipment and various electrical equipment as the carrier of information technology in industry-by-industry widespread use, particularly electronic component miniaturization, Highgrade integration and electronic instrument lightweight, high speed and digitizing; Electromagnetic signal, occurs botching routines because it is subject to outside electromagnetic interference, thereby has serious consequences, and therefore must take various effective safeguard procedures, could ensure its interference-free and paralysis.Reveal from electromagnetic signal the aspect of giving away secrets, no matter military secrecy or trade secret, by electromagnetic leakage, great loss is caused to relevant unit in capital, must take corresponding shielding measure for this reason, prevent electromagnetic signal leakage and detected, in case give away secrets; From prevention Contamination of Electromagnetic Wave, now the protection of various electromagnetic pollutions harm is caused to the great attention of environmental administration and the parties concerned, shielding electromagnetic pollution makes it be limited to certain area, has become one of research topic that field of Environment Protection enlivens the most.

Summary of the invention

The deficiency existing for prior art, the technical problem to be solved in the present invention is, a kind of coating is provided, and has good shielding effect, and effectively shielding electromagnetic wave, and coating has good viscosity, and adsorptive power is large, can be orderly for a long time.

For solving the problems of the technologies described above, technical scheme of the present invention is, a kind of coating with effectiveness, and its raw material by following parts by weight is made:

Epoxy resin 15-25 part, silicone rubber 10-20 part, polyvinyl alcohol 5-9 part, stearic acid 3-5 part, silane coupling agent 1-3 part, diatomite 5-7 part, glass microballon 4-9 part, flow agent 3-7 part, red iron oxide 2-4 part, Vinyl Acetate Copolymer 1-3 part, copper powder 10-15 part.

Optimisation technique scheme of the present invention is, a kind of coating with effectiveness, and its raw material by following parts by weight is made:

20 parts of epoxy resin, 15 parts of silicone rubbers, 7 parts of polyvinyl alcohol, 4 parts of stearic acid, 2 parts of silane coupling agents, 6 parts, diatomite, 6 parts of glass microballons, 5 parts of flow agents, 3 parts of red iron oxides, 2 parts of Vinyl Acetate Copolymer, 13 parts of copper powders.

The invention has the beneficial effects as follows, coating of the present invention, has good shielding effect, and effectively shielding electromagnetic wave, and coating has good viscosity, and adsorptive power is large, can be orderly for a long time.
