Abstract
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. The invention adopts cheap polysiloxane, polyurethane binder and titanium dioxide powder to prepare a multifunctional coating with self-cleaning, anti-ultraviolet and super-hydrophobic properties. A multifunctional outdoor fabric can be obtained by applying the multifunctional coating to the blended warp knitted fabric through a simple process. This product can take advantage of the ability of titanium dioxide to absorb ultraviolet rays, and can greatly degrade the organic pollutants on the surface of the fabric. At the same time, the coating with polysiloxane as the main component will not be photodegraded by titanium dioxide, and the aging fastness of the fabric is very good. ensure. It also has a super-hydrophobic function, which can effectively shield a large amount of liquid droplets outdoors. The cost of raw materials is low, the process is simple, the difficulty of technical transformation is small, and it is 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...
