Problems solved by technology

[0004] Ordinary flame-retardant coatings mainly rely on the penetration of flame-retardant glue into the fabric structure to obtain flame retardancy. Therefore, for thick and compact fabrics, the flame-retardant performance of flame-retardant coatings is difficult to meet the flame-retardant requirements.
Although the technical means disclosed in the Chinese Patent Publication CN1635211A can solve the problem of low flame-retardant performance after the flame-retardant coating of heavy fabrics, it adds a mechanical foaming process, and the product obtained after coating does not have waterproof and moisture-permeable properties. It can only be used in occasions where the flame retardant performance of the fabric is required
The coating and bonding finishing process is complicated, the operation requirements are high, and the solvent recovery process in the wet coating process is cumbersome, and there are many types of flame retardants added, and the added amount is high, so the production cost is high and the economic benefit is low.
In addition, the halogen series flame retardants and antimony series flame retardants used are currently restricted by environmental protection regulations

Embodiment 1

[0027] First, the following components by weight are uniformly mixed into a fabric coating slurry:

[0028] 100 parts of hydrophilic polyether polyurethane resin

[0029] 10 parts of halogen-free phosphorus-based particle flame retardant

[0030] 25 parts of non-polar solvent toluene

[0031] Non-polar solvent xylene 5 parts

[0032] Among them, the particle diameter of the halogen-free phosphorus-based particle-type flame retardant is less than 20 μm.

[0033] Secondly, the above-mentioned fabric coating slurry is evenly coated on the surface of the base fabric in a dry coating method to form a coating; finally, before the coating is dry, it is heated and dried. The heating and drying steps are divided into low-temperature pre-baking and high-temperature baking. The low-temperature pre-baking temperature is 50°C, and the pre-baking time is 4 minutes; the high-temperature baking temperature is 110°C, and the baking time is 4 minutes. After drying, a highly waterproof, high...

Abstract

The invention discloses a high-waterproof high-moisture-permeable flame-retardant coating fabric and a production method thereof. The fabric comprises base cloth and a high-waterproof high-moisture-permeable flame-retardant coating, wherein high-waterproof high-moisture-permeable flame-retardant is a polyurethane non-porous layer, and the flame retardant used in the coating layer is a halogen free particle flame retardant. The production method comprises the following steps of: uniformly spreading fabric coating slurry which is prepared by mixing hydrophilic polyurethane resin, an organic solvent, an additive and the flame retardant on the base cloth; and drying the base cloth to obtain the high-waterproof high-moisture-permeable flame-retardant coating product with the hydrophilic polyurethane non-porous layer. The coating fabric of the invention has high waterproofness and moisture-permeability and extremely high flame resistance. The coating fabric is used on particular occasions when high requirements on waterproofness, and moisture-permeability and fire resistance are required, can be used for preparing protective garments and the fabrics of protective equipment of departments such as fire control, metallurgy, petroleum and national defense, the fabrics of tents and the like, and therefore has greater economic and social benefits.

Description

technical field [0001] The invention relates to a highly waterproof and highly moisture-permeable flame-retardant coated fabric. Background technique [0002] Currently on the market, the flame retardant treatment of fabrics mostly adopts flame retardant padding finishing and flame retardant coating finishing. Among them, the flame retardant coating finishing will not affect the performance of the uncoated surface of the fabric, and has better safety and security. Comfort is accepted by more and more people. The waterproof and moisture-permeable finishing of fabrics includes high-density organization of hygroscopic fibers, coating finishing and laminating finishing, among which coating finishing is widely used because of its good product performance, simple process and low cost. [0003] At present, the coating finishing technology that combines flame-retardant and waterproof and moisture-permeable coating finishing is relatively rare in the market. This is mainly because ...
