Example Embodiment
[0010] Example 1:
[0011] An environmentally-friendly polyvinyl chloride coating whose components are proportioned by mass percentage: polyvinyl chloride resin 35%, dioctyl phthalate 10%, polyethylene resin 15%, talc 10%, rutile titanium dioxide 8%, polyether modified polysiloxane 5%, N-hydroxyethyl ethylamine 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 turn, and keep it at 70℃~80℃ Stir at temperature for 20-40 minutes, then add other components, continue to stir for 20-40 minutes, put the material in a sand mill for 3 to 5 times to make the particle size of the mixture less than 25μm, that is, the environmental protection Type PVC coating.
