Problems solved by technology

[0004] 1. Ordinary coated fabrics only have a single function (such as only high water pressure or only moisture permeability, etc.)
[0005] 2. Ordinary coated fabrics do not have long-term wearability, and the relevant key physical properties are easily lost when damaged by external forces or during the washing process (the hydrostatic pressure decreases rapidly, and the flame retardant effect is lost);
[0006] 3. Ordinary coated fabrics cannot meet the requirements of improving the visibility of the human body so as to improve the safety of special types of personnel
[0007] 4. The flame retardancy of ordinary coated fabrics is generally used in home textile products, and it is difficult to solve the weakness of hard hand feeling and insufficient long-lasting flame retardancy for clothing flame retardancy
[0008] 5. Ordinary coated flame-retardant fabrics have poor twist resistance and weak peeling strength when the rubber surface is cold-resistant below -30°C
[0009] 6. Ordinary coated flame retardant fabrics cannot simultaneously have excellent flame retardancy, effectively suppress smoke and prevent dripping
[0010] 7. It is difficult for flame-retardant powder and oil-resistant oil to dissolve effectively in polyurethane resin, and it is easy to produce powder aggregation, which cannot be coated with a doctor blade, resulting in unbalanced flame retardancy
[0011] 8. Ordinary flame retardant powders and oil retardants on the market are not good in environmental protection, and do not meet oeko-tex standard 100, environmental protection requirements of REACH Act

Abstract

The invention discloses a flame-retardant coating fabric high in moisture-penetrability. The flame-retardant coating fabric high in moisture-penetrability comprises a first base coating and a second base coating, wherein the first base coating is obtained by drying a sizing agent which is prepared from the following components in parts by mass: 100 parts of polyurethane resin, 38-42 parts of bromoethane, 19-21 parts of diantimony trioxide, 4.5-5.5 parts of zinc borate, 4-5 parts of a bridging agent, 1.6-2 parts of an accelerant, 1.4-1.6 parts of a washable agent and 9-11 parts of phosphate ester flame-retardant oil. The second base coating is obtained by drying a sizing agent which is prepared from the following components in parts by mass: 100 parts of polyurethane resin, 38-42 parts of bromoethane, 19-21 parts of diantimony trioxide, 4.5-5.5 parts of zinc borate, 4-5 parts of the bridging agent, 1.6-2 parts of the accelerant, 1.4-1.6 parts of the washable agent and 9-11 parts of phosphate ester flame-retardant oil. The flame-retardant coating fabric high in moisture-penetrability is small in smoke generation quantity, free of molten drop, high in flame-retardant effect and highly washable; the flame-retardant substance has a small possibility of hydrolyzing.

Description

technical field [0001] The invention relates to a flame-retardant coating fabric with high moisture permeability, which belongs to the technical field of textile fabrics. Background technique [0002] At present, coated fabrics only have a single function, which cannot satisfy the long-term operation of the human body in relatively harsh environments (high humidity, poor air circulation, such as mining industry and oil well operators), which is not conducive to special types of work (traffic police, patrol police, road cleaning personnel) ) In the daily operation process, due to the insufficient visibility of the fabric, it is impossible to protect and protect the safety of the human body, which is not conducive to the implementation of special circumstances (such as fire fighting, accidental explosion, and burning). The fabric only has combustion-supporting properties, which will cause burns and burns to the human body [0003] Specific issues: [0004] 1. Ordinary coate...
