Embodiment 1

[0011] An environment-friendly polyvinyl chloride coating, its components are proportioned by mass percentage: 35% polyvinyl chloride resin, 10% dioctyl phthalate, 15% polyethylene resin, 10% talcum powder, rutile titanium dioxide 8%, polyether modified polysiloxane 5%, N-hydroxyethylethylamine triacetic acid 3%, polyether ester amide 3%, calcium zinc stabilizer 1.5%, polyoxyethylene amide 0.5%, stearic acid Calcium 1%, Polyisocyanate 8%.

[0012] Preparation method: (1), weigh each component according to the weight ratio; (2), add polyvinyl chloride, dioctyl phthalate, and calcium zinc stabilizer into the mixer in sequence, and heat Stir at high temperature for 20-40 minutes, then add other components, continue to stir for 20-40 minutes, put the material into a sand mill and grind it for 3-5 times, so that the particle size of the mixture is less than 25 μm, that is, the above-mentioned environmental protection type polyvinyl chloride paint.

Embodiment 2

[0014] An environment-friendly polyvinyl chloride coating, its components are proportioned by mass percentage: polyvinyl chloride resin 70%, dioctyl phthalate 5%, polyethylene resin 5%, talcum powder 5%, rutile titanium dioxide 3%, polyether modified polysiloxane 3%, N-hydroxyethylethylamine triacetic acid 2%, polyether ester amide 1%, calcium zinc stabilizer 0.5%, polyoxyethylene amide 0.5%, stearic acid Calcium 1%, Polyisocyanate 4%.

[0015] Preparation method: (1), weigh each component according to the weight ratio; (2), add polyvinyl chloride, dioctyl phthalate, and calcium zinc stabilizer into the mixer in sequence, and heat Stir at high temperature for 20-40 minutes, then add other components, continue to stir for 20-40 minutes, and put the material into a sand mill for grinding 3-5 times, so that the particle size of the mixture is less than 25 μm, that is, the above-mentioned environmental protection type polyvinyl chloride paint.

Abstract

The invention discloses an environmentally friendly polyvinyl chloride coating. The coating comprises, by mass, 35-70% of polyvinyl chloride resin, 5-10% of dioctyl phthalate, 5-15% of polyethylene resin, 5-10% of talcum powder, 3-8% of rutile titanium dioxide, 3-5% of polyether modified polysiloxane, 2-3% of N-hydroxyethylethylamine triacetic acid, 1-3% of polyether esteramide, 0.5-1.5% of a calcium and zinc stabilizer, 0.1-0.5% of polyoxyethylene amide, 0.5-1% of calcium stearate and 4-8% of polyisocyanate. The environmentally friendly polyvinyl chloride coating has the advantages of excellent weather resistance, excellent temperature tolerance, excellent corrosion resistance and good environmental protection performance, and can be used in the chemical industry, the petroleum industry, the pharmacy industry and the food industry to form protection coat layers of surfaces of devices, buildings and members.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an environment-friendly polyvinyl chloride coating. Background technique [0002] The anti-corrosion coatings in the current market generally have defects such as thin and brittle paint films, low adhesion, and short service life. Anti-corrosion coatings will have very important practical significance. Polyvinyl chloride is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It has the advantages of high chemical resistance, stable physical and chemical properties, and low price. It has been widely used in many fields. Applying polyvinyl chloride to anti-corrosion coatings has good social and economic benefits. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly polyvinyl chloride coating with excellent weather resistance, temperature resistance and corrosion resistance.
