Embodiment 1

[0012] Modified high-chlorinated polyethylene antirust paint, including the following raw materials in parts by mass: 72 parts of high-chlorinated polyethylene resin, 10 parts of polyvinyl chloride resin, 5 parts of zinc borate, 8 parts of tributyl citrate, 0.6 parts of polyvinyl acetate, 0.1 parts of triphenyl phosphite, 8 parts of iron oxide red, 8 parts of mica powder, 30 parts of toluene, and 15 parts of ethyl acetate.

[0013] The preparation method of this embodiment: according to the mass ratio, add high-chlorinated polyethylene resin and polyvinyl chloride resin into toluene, stir well and then add ethyl acetate, zinc borate, tributyl citrate, polyvinyl acetate, ethylene oxide Triphenyl phosphate, red iron oxide and mica powder are stirred evenly to obtain a modified high-chlorinated polyethylene flame-retardant and anti-rust coating.

[0014] The finished product was tested for performance, and the test results are shown in Table 1.

Embodiment 2

[0016] Modified high-chlorinated polyethylene antirust paint, including the following raw materials in parts by mass: 78 parts of high-chlorinated polyethylene resin, 12 parts of polyvinyl chloride resin, 7 parts of zinc borate, 10 parts of tributyl citrate, 1.2 parts of polyvinyl acetate, 0.5 parts of epoxidized soybean oil, 10 parts of iron oxide red, 14 parts of mica powder, 40 parts of toluene, and 18 parts of ethyl acetate.

[0017] The preparation method of this embodiment is the same as that of Example 1, wherein the stabilizer is epoxidized soybean oil. The finished product was tested for performance, and the test results are shown in Table 1.

Embodiment 3

[0019] Modified high-chlorinated polyethylene antirust paint, including the following raw materials in parts by mass: 76 parts of high-chlorinated polyethylene resin, 11 parts of polyvinyl chloride resin, 6 parts of zinc borate, 9 parts of tributyl citrate, 0.8 parts of polyvinyl acetate, 0.4 parts of xylitol, 9 parts of iron oxide red, 12 parts of mica powder, 35 parts of toluene, and 16 parts of ethyl acetate.

[0020] The preparation method of this example is the same as that of Example 1, wherein the stabilizer is xylitol, and the performance test of the finished product is carried out, and the test results are shown in Table 1.

Abstract

The invention provides modified high chlorinated polyethylene antirust coating and a preparation method thereof. The modified high chlorinated polyethylene antirust coating comprises the following raw materials in parts by mass: 72-78 parts of high chlorinated polyethylene resin, 10-12 parts of polyvinyl chloride resin, 5-7 parts of zinc borate, 8-10 parts of tributyl citrate, 0.6-1.2 parts of polyvinyl acetate, 0.1-0.5 part of a stabilizer, 8-10 parts of iron oxide red, 8-14 parts of mica powder, 30-40 parts of toluene and 15-18 parts of ethyl acetate. The modified high chlorinated polyethylene antirust coating has good resistance to acid and base and salt water resistance, is relatively short in drying time, convenient to coat and free of limitation of seasons and can be cured at a low temperature; the preparation method provided by the invention is simple and practicable and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a modified high-chlorinated polyethylene antirust coating and a preparation method thereof. Background technique [0002] In a relatively harsh environment, heavy-duty anti-corrosion coatings are particularly important, which can protect the device from rapid corrosion, thereby prolonging the life of the device. Generally, heavy-duty anti-corrosion coatings have good acid and alkali resistance, and the paint film is relatively thick, but there are still shortcomings such as poor acid and alkali resistance and salt water resistance, and long drying time. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the field of coatings. Contents of the invention [0004] The purpose of the invention is to overcome the deficiencies in the prior art and propose a modified highly chlorinated polyethylene antirust coating and...
