Problems solved by technology

[0003] For example, the Chinese published patent CN 101422672A discloses a method for preparing a flame-retardant and washable filter material. The base material is soaked in an aqueous solution of flame-retardant glue made of water-based polyurethane, cyclic phosphate flame retardant, and sodium dihydrogen phosphate in a certain proportion. , although the obtained filter material has flame retardant properties, but its degree of polymerization is low, so the obtained filter material has a high moisture regain. If it is used in the field of air filtration, when filtering particulate matter in the air, it is easy to be affected by moisture, resulting in Clogged filter material, shortened service life

Abstract

The invention discloses a flame-retardant non-woven fabric and a preparation method thereof. The flame-retardant non-woven fabric comprises 40 to 60wt% of polyester fiber, and 60 to 40wt% of a mixture of a flame retardant and a binder; the flame retardant is ammonium polyphosphate flame retardant or ammonium polyphosphate melamine flame retardant, and accounts for 40 to 70wt% of the mixture; and the binder is acrylic resin or styrene acrylic emulsion. The flame-retardant non-woven fabric is low in hygroscopicity, high in stiffness, low in cost, and can be used in the field of air filtration; the preparation method is simple; and problems such as dampness penetration or blocking are not caused.

Description

technical field [0001] The invention relates to a flame-retardant non-woven fabric and a production method thereof. Background technique [0002] At present, the web forming methods of non-woven fabrics on the market mainly include dry method, wet method, air-laid method, spunbond method, and melt-blown method. Among them, non-woven fabrics made by wet method have the advantages of high production speed and low processing cost. . The reinforcement method of the fiber web forming the wet-laid non-woven fabric is to rely on an external adhesive to produce adhesion. If non-woven fabrics are to achieve flame-retardant effects, flame retardants, such as halogenated flame retardants, are generally added to the adhesive. Rarely used in air filter materials. [0003] For example, the Chinese published patent CN 101422672A discloses a method for preparing a flame-retardant and washable filter material. The base material is soaked in an aqueous solution of flame-retardant glue made...
