Abstract
The invention relates to a strippable anti-pollution coating for a decorative layer of an elevator. The coating is characterized by comprising a component A and a component B, wherein the ratio of the component A to the component B is (0.2-0.8):(0.8-0.2); the component A comprises the following components in part by weight: polyethylene-vinyl acetate 1:(2-5), 0.1 to 0.5 part of sodium tripolyphosphate, 1 to 10 parts of stearate, 1 to 5 parts of talcpowder, 0 to 5 parts of pigment, 1 to 5 parts of cationic surfactant and 10 to 20 parts of zinc oxide; and the component B is acetaldehyde modified polyvinyl alcohol. The coating is obtained by mixing the component A and the component B in a proportion and stirring uniformly. The coating has stable coating uniformity, a good antifouling property and high crack resistance, and is short in reaction time.
Description
Technical field

Technical problem to be solved by this invention provides the peelable non-staining coating that a kind of elevator ornament layer is used, and has good didirtresistance, and is easy to peel off.
For solving the problems of the technologies described above, the present invention realizes like this
The peelable non-staining coating that the elevator ornament layer is used comprises: A, B component, A component: B component=0.2-0.8:0.8-0.2;
The A component comprises the following component in weight part:
Polyethylene vinyl acetate (1:2-5), tripoly phosphate sodium STPP 0.1-0.5, stearate 1-10, talcum powder 1-5, pigment 0-5, cats product 1-5, zinc oxide 10-20;
The B component comprises the following component in weight part:
Polyvinyl alcohol 10-20, properties-correcting agent 1-5, catalyzer 1-5;
Properties-correcting agent is acetaldehyde; Catalyzer is triethylamine;
Preparation process is as follows:
(1), preparation B material: take triethylamine as catalyzer, take acetaldehyde as properties-correcting agent, at 10-30 ℃ of lower reaction 3-5h, then at 40-50 ℃ of reaction 0.5-2h, the consumption of acetaldehyde is to make polyvinyl alcohol modification 10-30%, and then the pH value with sour conditioned reaction liquid is 5-7;
(2), according to ratio mix A, B component, stir, and get final product.Add suitable quantity of water according to service condition and regulate viscosity.
Strippable anti-fouling paint of the present invention has stable film uniformity and good didirtresistance and the crack resistance energy of being coated with, and the reaction times is short.
