Polysiloxane, preparation system thereof, polysiloxane-polyurethane-titanium dioxide mixed paint and application of paint

Abstract

The invention relates to the technical field of functional preparation of outdoor fabrics, and particularly relates to a polysiloxane, a preparation system thereof, a polysiloxane-polyurethane-titanium dioxide mixed paint and application of the paint. According to the invention, a multifunctional coating having self cleaning performance, ultraviolet resistance and superhydrophobicity is prepared from low-cost polysiloxane, polyurethane adhesive and titanium dioxide powder. A multifunctional outdoor fabric can be obtained by applying the multifunctional coating to a blended warp knitting fabric through a simple process. By using the ultraviolet absorption capability of titanium dioxide, the product can greatly degrade organic pollutants on the surface of the fabric; and meanwhile, the coating taking polysiloxane as a main component can not be subjected to photodegradation of the titanium dioxide, thereby favorably ensuring the anti-aging fastness of the fabric. The product itself has a superhydrophobic function, thereby being capable of effectively blocking a large amount of water droplets outdoors. The product has the advantages of low raw material cost, simple process and low technological transformation difficulty, thereby being suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of functional preparation of outdoor fabrics, in particular to a polysiloxane and its preparation system, a polysiloxane-polyurethane-titanium dioxide mixed coating and the application of the coating. Background technique [0002] With the development of the economy, people in cities have increasing demands for outdoor life and sports, and more and more attention has been paid to outdoor products. People's favorite places for outdoor activities are mostly lakes, streamsides, open mountains and forests, etc. The biggest difference between these outdoor environments and urban life lies in high-intensity sunlight, relatively humid water environment and many organic floating objects. Sunlight contains a lot of ultraviolet rays, long-term exposure will cause serious damage to human skin and other organs, and too humid environment will also make people feel inconvenient, too much organic floating matter will easil...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing mass production technologies can only solve the above-mentioned part of the problems. For example, the patent for invention with the application publication number CN106012568A provides a method for preparing anti-ultraviolet tent cloth using zinc oxide as a coating filler; the application publication number is CN105128434A The invention patent of the company provides a preparation method of fire-resistant and flame-retardant tent fabric
