Abstract

The invention relates to a waterborne environment-friendly membrane and a preparation method thereof. The waterborne environment-friendly membrane is prepared through the steps that waterborne polyurethane resin, a defoaming agent, a dispersing agent and the like are taken as raw materials to be mixed and stirred to prepare a spraying material, then spraying is conducted, and finally a two-time curing method is adopted. The preparation method has the advantages that a preparation technology is relatively mature, and the stability is high; the prepared waterborne environment-friendly membrane has the advantages that the membrane is an elastic coating and can reduce damage of external force to a real object and isolate direct contact of the real object and the outside, environmental friendliness is achieved, wear resistance is high, skid resistance is achieved, the application range is wide, and the adhesive force is high.

Description

technical field [0001] The invention belongs to a membrane material preparation process, and in particular relates to a water-based environmental protection membrane and a preparation method thereof. Background technique [0002] Most of the products currently on the market, such as wood flooring, plastic flooring, wallpaper, machine casings, refrigerators, etc., do not have surface protection layers, or rarely use solvent-based protection layers. environmental protection and many other issues. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a water-based environmental protection membrane and a preparation method thereof. [0004] The technical solution adopted in the present invention is: a water-based environmental protection film, including the following raw materials in parts by weight: 90-100 parts of water-based polyurethane resin; 0.2-0.6 parts of defoaming agent; 0.4-1.2 parts of di...
