Composite sun-shading material of acrylic acid polyvinyl chloride polymer material

Abstract

The invention provides a composite sun-shading material of an acrylic acid polyvinyl chloride polymer material, which mainly comprises the following raw materials: sunlight cloth fabric and coating slurry; wherein the sunlight fabric is woven by yarns coated with polyvinyl chloride and has a certain opening ratio and light transmittance; the coating slurry consists of acrylic emulsion, titanium dioxide filler, a foam stabilizer and a flame retardant; according to the invention, the acrylic emulsion serving as a main component of the coating slurry is synthesized through polymerization reactionby adopting acrylic monomer and C1-C8 acrylic acid alkyl ester thereof to synthesize an acrylic ester slurry agent copolymer adhesive and adding high-performance acrylic ester adhesive, and the curing point of the acrylic emulsion is about 150 DEG C; the problem that the foaming surface of the coating fabric is sticky is fundamentally solved, the defect rate of the product is reduced, the surfaceflatness of the product is improved, the cleanliness is increased, the product types are increased, and the core competitiveness of an enterprise is improved by playing a great promotion role for market promotion and product sale.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a composite sunshade material of acrylic polyvinyl chloride polymer materials. Background technique [0002] Sunshine fabric is woven from polyvinyl chloride-coated yarn, which has a certain porosity and light transmittance. It is made by adding slurry with acrylic acid as the main component on the basis of sunshine fabric and then processed through several processes. It is mainly used to produce roller blinds, vertical curtains, seat cushions, etc. for night use. The market demand is very large, and there are many Great prospects for promotion. [0003] But there are some difficult problems in the production process as follows: [0004] On the one hand, due to the different properties of the polyvinyl chloride in the polymer composite sunshade material and the acrylic system in the coating slurry, the high temperature resistance of the two is very different. The melting point...

Problems solved by technology

[0004] On the one hand, due to the different properties of the polyvinyl chloride in the polymer composite sunshade material and the acrylic system in the coating slurry, the high temperature resistance of the two is very different. The melting point of polyvinyl chloride is about 140 degrees Celsius, while The curing temperature of acrylic acid is about 150 degrees Celsius. The full-shade sunscreen fabric needs to be back-coated with polyvinyl chloride polymer composite material from the acrylic foam system and cured to form a film. In this case, the synthesis of acrylic acid and polyvinyl chloride is undoubtedly contradictory. , it often occurs that the acrylic acid has not been cured and the polyvinyl chloride has melted and burst into wires, causing the polymer composite material to stick, the surface is not smooth, and the product quality is difficult to meet customer needs
