Problems solved by technology

[0002] In the prior art, as a surface treatment agent for antifouling and easy-cleaning treatment on the surfaces of plastics, fabrics, non-woven fabrics, wood, metals and ceramics, Due to the uneven dispersion of the coating surface after application and the extremely high surface tension of the coating, the surface of the coating is easily stained and difficult to clean
The coating formed by this type of surface treatment agent also has the disadvantages of poor solvent resistance and easy stickiness

Embodiment 1

[0038] Preparation of silicon-fluorine modified resin: Dow Corning Z-6030 silane (DOW CORNING) 5wt%, fluororesin 23-28 (Waker) 2wt%, acrylic resin YD582-2 (Far East Chemical) 5wt%, polyurethane resin HDBU-6025 (Shanghai Huide Resin Co., Ltd.) 30wt%, xylene (Wenxin) 18wt%, MEK (wantuming) 15wt%, DMF 25wt%; mix the above raw materials in proportion to obtain organic silicon fluorine modified resin;

[0039] Preparation of coating slurry (by weight): Weigh 100 parts of silicon-fluorine modified resin, slowly add 25 parts of curing agent HDN-75 (Huide), stir evenly, and then slowly add 25 parts of accelerator HDC- 01 (Huide), stir while adding, until the mixture is uniform, adjust the viscosity to 800-1500cp with butyl acetate (Wenxin), and let it stand for later use;

[0040] Use a 100-mesh anilox wheel to print on the surface of cowhide, PU leather, and PVC leather respectively, dry at 150°C for 3 minutes, and dry at 170°C for 15 seconds, and the coating thickness is 1-10 μm.

Embodiment 2

[0044]Preparation of silicon-fluorine modified resin: silicone resin TEGO PROTECT 5001 (TEGO) 2.6wt%, acrylic resin YD582-2 (Far East Chemical) 3.4wt%, polyurethane resin HDBU-6025 (Huide) 24wt%, 150# solvent 20wt% %, butyl acetate 50wt%, the above-mentioned raw materials are mixed uniformly in proportion to obtain silicon-fluorine modified resin;

[0045] Preparation of coating slurry (by weight ratio): Weigh 100 parts of silicon-fluorine modified resin, slowly add 20 parts of curing agent HDN-75 (Huide), stir evenly, and then slowly add accelerator HDC-01 ( Huide) 5 parts, add and stir until the mixture is uniform, use about 150 parts of tetrahydrofuran (Wenxin) to adjust the viscosity to 800-1500cp, and let it stand for later use;

[0046] Use a 60-mesh screen roller to roll coat the surface of the PVC leather, dry at 130°C for 3 minutes, and dry at 160°C for 60 seconds, with a coating thickness of 10-30 μm.

Abstract

The invention provides silicon-fluorine modified resin and a method for preparing antifouling and easy-clean surface modified coating by utilizing the silicon-fluorine modified resin, wherein the silicon-fluorine modified resin is a modified surface processing agent which has uniform structure, extremely low surface tension, extremely good drainage and antifouling effect and excellent physical and mechanical properties and solvent resistance. The silicon-fluorine modified resin comprises the following raw materials in percentage by weight: 0.1-20 percent of silicon resin, 0-10 percent of fluororesin, 0.1-20 percent of hydroxyl acrylate resin, 20-50 percent of hydroxyl polyurethane resin and 20-70 percent of solvent. Coating slurry comprises the following components by weight part: 100 parts of silicon-fluorine modified resin, 10-40 parts of curing agent, 10-40 parts of accelerating agent and 10-200 parts of solvent, and the coating is constructed through printing, roller painting, spraying, brushing, dip-coating, and the like. The silicon-fluorine modified resin and the coating thereof have excellent antifouling and easy-clean functions and better comprehensive physicochemical property, and can be widely applied to the fields of furniture, automotive trims and seats, clothes, shoe leather, bags, and the like.

Description

(1) Technical field [0001] The invention relates to an organosilicon and fluorine-modified resin as a surface treatment agent, and a method for preparing an antifouling and easy-to-clean surface modification coating by using the organosilicon and the fluorine-modified resin. (2) Background technology [0002] In the prior art, it is used as a surface treatment agent for antifouling and easy-cleaning treatment on the surfaces of plastics, fabrics, nonwovens, wood, metals and ceramics. The surface tension is extremely high, making the surface of the coating highly susceptible to stains and difficult to clean. The coating formed by this type of surface treatment agent also has the disadvantages of poor solvent resistance and easy stickiness. (3) Contents of the invention [0003] The purpose of the present invention is to provide a modified surface treatment agent with uniform structure, extremely low surface tension, excellent physical and mechanical properties, and solv...
