Embodiment Construction

[0015] The fabric PVC coating surface treatment agent of the present invention and its preparation method are further described in detail below.

[0016] The anti-ultraviolet function in this invention is mainly composed of acrylic monomers with hydroxyl groups having anti-ultraviolet functions, and acrylic monomers with other functional groups, polyethylene series monomers, copolymers and solvents are added.

[0017] The acrylic resin used in the invention is composed of acrylic monomers containing hydroxyl groups with ultraviolet absorbing functions, acrylic monomers containing non-active groups and acrylic monomers containing carbonyl groups.

[0018] In this invention, the hydroxyl-containing acrylic monomer having the function of absorbing ultraviolet rays in Chemical Formula 1 is specially used, thereby improving the weather resistance to ultraviolet rays. The above-mentioned monomers have been commercially produced by Otsuka Chemical Company, and Chemical Formula 1 is a...

Abstract

The invention discloses a PVC coating surface finishing agent for fabric and a preparation method thereof. The surface finishing agent is characterized by comprising acrylic resin, polyethylene monomers, copolymer and solvent, wherein the acrylic resin comprises acrylic monomers containing hydroxy groups with ultraviolet absorption function, acrylic monomers containing non-functional groups and acrylic monomers containing carbonyl groups; and the acrylic monomers containing the hydroxy groups with the ultraviolet absorption function approximately calculated by weight account for 0.5 to 5 weight percent, the acrylic monomers containing the non-functional groups account for 50 to 70 weight percent of unsaturated monomers; and a polymerization initiator accounts for 2 to 20 weight percent of the total weight of the unsaturated monomers. The PVC coating surface finishing agent for the fabric has the advantages of excellent light resistance, weather resistance and stain resistance.

Description

technical field [0001] The invention relates to a fabric PVC coating surface treatment agent and a preparation method thereof. Background technique [0002] At present, the PVC coating of the fabric is aging due to the breakage of the PVC molecular chain under long-term sunlight, which reduces the physical properties of the fabric coating material and affects the service life of the membrane material. The surface of the membrane material is easily stained with dust and dirt, and does not have a self-cleaning function. The light resistance, weather resistance and pollution resistance of the coating are not good. Contents of the invention [0003] The object of the present invention is to provide a fabric PVC coating surface treatment agent with excellent light resistance, weather resistance and pollution resistance and a preparation method thereof. [0004] The object of the present invention is achieved through the following technical solutions. [0005] A fabric PVC co...
