Abstract

The invention relates to the technical field of waterproof spraying, in particular to a waterproof spraying agent and a preparation method and application thereof. The waterproof spraying agent is prepared from, by weight, 20-32 parts of fluorocarbon resin, 0-8 parts of acrylic resin, 1-3 parts of polysilazane, 0-3 parts of other auxiliaries and 55-78 parts of organic solvent A. Fluorocarbon resinserves as matrix resin and is dissolved in an organic solvent A and can be used in a normal temperature; the organic solvent A volatilizes after coating to enable the fluorocarbon resin to form a waterproof breathable film, so that the waterproof effect is improved; the polysilazane is mixed into the fluorocarbon resin to play a role in reinforcing, so that the waterproof aging of the waterproofbreathable film is improved; furthermore, if less than 8 parts by weight of acrylic resin is added, the acrylic resin has a synergistic effect with fluorocarbon resin, so that the adhesiveness and thefilm-forming property of the waterproof spraying agent coated on the surface of the carrier are improved, and the flexibility of the waterproof breathable film is improved.

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...
