Abstract

The invention provides an insulating protecting paint for the surface of a metal, which can effectively protect the non-processing surface in the process of carrying out chemical processing on a metal material. The insulating protecting paint of the invention is prepared through mixing a vinyl perchloride anticorrosive varnish, sultan IV (C24H20ON4), a silica sol, and cobalt nitrate according to a preparation ratio of 95-98:2-3:1:1.

Description

A kind of insulation protection lacquer that is used for the metallic surface

Technical field

The present invention relates to a kind of insulation protection lacquer, this insulation protection lacquer can be coated on the metallic surface, is used to protect metal carrying out like surface treatment such as plating, chemistry milling and adding the protection of man-hour to non-processing and treat surface.

Background technology

Along with science and technology development, many novel materials are applied to manufacture field at present, and the hardness of material is increasing, adopt traditional machining process more and more difficult, and tooling cost is also increasingly high, thereby people are seeking new working method.New process method adopts chemical process in a large number, for example adopts chemistry milling etc., when utilizing chemical process and chemical method for treating surface; Because material require contact chemical liquid and high temperature; Often need some non-finished surfaces of metallic substance effectively be protected, therefore need development can be able to bear strong corrosion and pyritous insullac, this kind lacquer need have bonding strength preferably; Simultaneously after material is accomplished heat or surface treatment, more easily from being come off by protecting materials.

Summary of the invention

The object of the invention just provides a kind of can being able to bear strong corrosion and pyritous insulation protection lacquer, metallic substance is being carried out protect non-finished surface in chemical process or the chemical treating process effectively.

Insulation protection lacquer of the present invention is by chlorinated polyvinyl chloride antiseptic varnish, S (C ₂₄H ₂₀ON ₄), silicon sol, Xiao Suangu mixed preparing form, its configuration proportion is:

Chlorinated polyvinyl chloride antiseptic varnish 95%～98%;

S (C ₂₄H ₂₀ON ₄) 2%～3%;

Silicon sol 1%;

Xiao Suangu 1%.

The making flow process is: mixing → stirring → detection → use.

Concrete making method is:

A. in container, pour 95%～98% chlorinated polyvinyl chloride antiseptic varnish into;

B. in the chlorinated polyvinyl chloride antiseptic varnish, add 2%～3% S (C respectively successively equably ₂₄H ₂₀ON ₄), 1% silicon sol and 1% Xiao Suangu;

C. stir, detect its viscosity and transparency.

Insulation protection lacquer manufactured according to the present invention can be applied to the metallic surface, easily when metal carries out chemical process or chemical surface treatment; Non-finished surface is effectively protected, the part base solid material capability is not had influence, making processes is simple; After metal was accomplished processing, the insulation protection lacquer can crust naturally and peel off, if when it is come off fast; Can utilize heating means accelerator crust, enhance productivity.

Embodiment

Embodiment:

1. preparation of raw material: get 95% chlorinated polyvinyl chloride antiseptic varnish, 3% S, 1% silicon sol, 1% Xiao Suangu and a small amount of cerous nitrate.

2. liquid chlorinated polyvinyl chloride antiseptic varnish is weighed up with measuring device, treat to add the Sudan and silicon sol mixing successively behind the liquid stabilising, add Xiao Suangu and cerous nitrate during use.

3. insulation protection lacquer is brushed in the piece surface that needs protection equably, brush insulation protection lacquer thickness is 0.02mm, and the brush secondary is for well.

4. insulation protection is coated with lacquer and is coated between the part and can not produce bubble when applying.

5. the workpiece after applying is carried out chemical process or chemical surface treatment, corrosion or milling temperature are controlled at 90 ± 10 °.

6. after machining, part cleans through the hot water or cold water, with heat gun brushing insullac place is dried up, and the insulation protection lacquer of peeling off can not be reused.

This insulation protection lacquer is applicable to metallic substance piece surfaces processing insulation protections such as titanium alloy, superalloy, stainless steel, structure iron, coats with lacquer 1Cr with insulation protection of the present invention ₁₈Ni ₉Ti material parts, GH4169 material parts and ZGCr ₁₁Ni ₂The WMoV material parts makes an experiment, and its protection effect is very desirable.

Claims

1. an insulation protection that is used for the metallic surface is coated with lacquer, by chlorinated polyvinyl chloride antiseptic varnish, S (C ₂₄H ₂₀ON ₄), silicon sol, Xiao Suangu mixed preparing form, it is characterized in that: configuration proportion accounts for 95%～98% for the chlorinated polyvinyl chloride antiseptic varnish by weight percentage, S (C ₂₄H ₂₀ON ₄) accounting for 2%～3%, silicon sol accounts for 1%; Xiao Suangu accounts for 1%.
