Abstract

The invention relates to the technical field of waterproof spray, in particular to a waterproof spray, its preparation method and application. The waterproof spray includes the following raw materials in parts by weight: 20-32 parts of fluorocarbon resin, 0-8 parts of acrylic resin, polysilicon 1-3 parts of azane, 0-3 parts of other additives, 55-78 parts of organic solvent A. With fluorocarbon resin as the main resin and dissolved in organic solvent A, it can be used at room temperature. After coating, the organic solvent A volatilizes to form a waterproof and breathable film of fluorocarbon resin, which improves the waterproof effect. Polysilazane is mixed with fluorine The carbon resin plays a reinforcing role to improve the waterproof aging of the waterproof and breathable membrane; further, if the acrylic resin below 8 parts by weight is added, it will work synergistically with the fluorocarbon resin to improve the adhesion and film formation of the waterproof spray on the surface of the carrier Improve the flexibility of the waterproof and breathable membrane.

Description

technical field [0001] The invention relates to the technical field of waterproof spray, in particular to a waterproof spray, its preparation method and application. Background technique [0002] Ordinary clothing, shoes, bags and other items are not waterproof or stain-proof. Once in contact with water, they are easily soaked, wet, and stained. At present, there are mature waterproof products on the market, but their application process is complex, requiring professional equipment and strict temperature control, and the waterproof effect and timeliness are poor. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, one of the purposes of the present invention is to provide a waterproof spray, which can be used at normal temperature, and forms a waterproof and breathable film after coating, which improves the waterproof effect and has a longer waterproof effect. [0004] The second object of the present invention is to...
