Problems solved by technology

The conventional method of adding a cross-linking agent has the disadvantages of short pot life of glue, large waste, or the toxicity of the cross-linking agent, and poor environmental protection. The one-component type can overcome the above shortcomings, and is easy to use and basically no waste
[0009] There are patents related to water-based pressure-sensitive adhesives related to surface protection films, such as "Peelable Emulsion Pressure-Sensitive Adhesive and Pressure-Sensitive Adhesive Sheet" (Patent Publication No. CN1517422A) describes the composition and preparation of a peelable emulsion PSA method, which includes an acrylate emulsion polymer and an external crosslinking agent containing a water-dispersible polyisocyanate, but the reaction of the water-dispersible polyisocyanate with water in the emulsion reduces the crosslinking efficiency, thereby reducing the water resistance, and also leads to The pot life of the glue is significantly shortened
"Preparation Method of Emulsion Pressure Sensitive Adhesive for Moisture and Heat Resistance Surface Protection Film and Surface Protection Film" (Patent Publication No. CN101153208A) describes an emulsion pressure sensitive adhesive for moisture and heat resistance protection film. Reactive emulsifier, without fluorine modification method, still lacks in water resistance, and is not a one-component type

Abstract

The invention discloses a single-component water-borne pressure sensitive adhesive for a sun-proof and heat-insulating film. A fluorine-containing ethylene monomer is introduced in the polymerization process to carry out the modification by copolymerization, and the single-component water-borne pressure sensitive adhesive for the sun-proof and heat-insulating film, which consumes fewer emulsifiers and has excellent performance, is synthetized through a seed emulsion polymerization method by a reaction-type emulsifier. The invention further provides a preparation method of a sun-proof and heat-insulating film viscous layer. The prepared protective film viscous layer has favorable water resistance and weather resistance, can ensure no foaming, no swelling, no wrinkling and no flanging after being used for a long time as required.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a single-component water-based pressure-sensitive adhesive for a sunscreen and heat-insulating film. Background technique [0002] Sunscreen and heat insulation film is a new type of surface protection material developed to prevent ultraviolet / infrared radiation. The sunscreen and heat insulation film is based on polyester film, which has high transparency, high ultraviolet / infrared ray blocking rate, strong impact resistance and tear resistance, adjustable adhesion performance, and good adhesion to various surfaces. The time changes are small. Paste it on the surface of various car window glass, building materials, instruments, electronic products and other materials to avoid damage caused by ultraviolet / infrared radiation. The application of sunscreen and heat insulation film can not only effectively block the heat of solar radiation, reduce a lot of heat in the h...
