Problems solved by technology

[0003] The production process of waterproof and breathable materials is mostly monopolized by foreign companies. In recent years, some domestic manufacturers have begun to produce such materials, but the quality of each product is uneven, and it is impossible to form a unified quality standard
At present, waterproof and breathable materials mostly use the structural model of non-woven fabric + breathable polymer material + non-woven fabric, but looking at the waterproof and breathable materials produced at home and abroad, there are the following problems: 1) Most of the non-woven fabrics are made of polymer Acrylic (PP), although the non-woven fabric of this material also has its own advantages, but this type of non-woven fabric has low strength, poor durability, not high temperature resistance, and is very easy to age under long-term ultraviolet radiation; 2) breathable Polytetrafluoroethylene (EPTFE) is mostly used as polymer material. Although EPTFE enjoys many reputations in the industry, perfluorooctanoic acid ammonium (PFOA) must be used as raw material in its production process. PFOA is a strong carcinogen and is easy to handle. Operators on the production line bring great harm

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0021] Such as figure 1 As shown, this case involves a waterproof and breathable material, which is sequentially provided with an anti-ultraviolet coating 1, a high-temperature resistant coating 2, a first non-woven fabric layer 3, a biomass particle layer 4, and a second non-woven fabric layer from top to bottom. Layer 5 and flame retardant layer 6.

[0022] Wherein, the anti-ultraviolet coating 1 contains 20wt% of phenylethyl o-hydroxybenzoate, 30wt% of 2-(2'-hydroxyl-5'-methylphenyl)benzotriazole, 10wt% of p-toluene Resorcinol benzoate, 10wt% epoxy resin and 30wt% porous microspheres; phenylethyl o-hydroxybenzoate, 2-(2'-hydroxy-5'-methylphenyl)benzotri Azole and resorcinol p-toluate are both efficient, cheap and environmentally friendly ultraviolet absorbers. The conten...

Abstract

The invention discloses a waterproof and breathable material. The waterproof and breathable material is sequentially provided with an uvioresistant coating, a high-temperature-resistant coating, a first non-woven cloth layer, a biomass particle layer, a second non-woven cloth layer and a flame retardant layer, wherein the uvioresistant coating contains 20wt% of phenylethyl salicylate, 30wt% of 2-(2'-hydroxy-5'-methylphenyl) benzotriazole, 10wt% of p-toluylic acidresorcinol ester, 10wt% of epoxy resin and 30wt% of a porous microsphere. According to the material, the uvioresistant coating is additionally arranged at the outermost layer, and the problem of easiness in aging of non-woven cloth is solved; by the additional arrangement of the high-temperature-resistant layer and the flame retardant layer, the high-temperature resistance and the flame retardance of the waterproof and breathable material are improved, so that the service life of the waterproof and breathable material is prolonged; an environment-friendly biomass energy source is introduced as an intermediate breathable layer, so that the dustproof, damp-proof and breathable capabilities of the waterproof and breathable material are ensured, the production cost is reduced, and the production environment is enhanced.

Description

technical field [0001] The invention relates to the field of materials, in particular to a waterproof and breathable material for outdoor use. Background technique [0002] Waterproof and breathable materials generally include waterproof and breathable membranes and waterproof and breathable panels. Speaking of which, the waterproof and breathable membrane also has many functional characteristics that other waterproof materials do not have. Waterproof and breathable materials are mainly used outdoors, mostly in construction, transportation facilities, outdoor lighting, outdoor communication equipment, solar energy equipment, etc. [0003] The production process of waterproof and breathable materials is mostly monopolized by foreign companies. In recent years, some domestic manufacturers have begun to produce such materials, but the quality of each product is uneven, and it is impossible to form a unified quality standard. At present, waterproof and breathable materials mos...
