Production process for fire retardant nonwoven fabric belts

Abstract

The invention relates to a technique for producing flame retardant non-woven tapes. The invention relates to a technique for producing flame retardant non-woven fabrics. The technique is as follows: firstly, polyester non-woven fabrics are used as raw materials and pass through a steeping tank which is filled with liquid phosphor-nitrogen flame retardant to form a flame retardant layer; secondly, the non-woven fabrics which are steeped with the phosphor-nitrogen flame retardant are dried through a high-temperature oven the temperature of which is controlled to be between 100 and 150 DEG C; thirdly, the non-woven fabrics are wrapped by a winding machine, split by a splitting machine and then packaged into finished products. The technique selects the prior polyester non-woven fabrics as matrixes, covers a layer of colorless, odorless and transparent liquid phosphor-nitrogen flame retardant on the surface of the non-woven fabrics and then dries and splits the non-woven fabrics. The production technique is simple; the performance of the products is superior; and the products have strong practicability and economical efficiency.

Description

Production process of flame-retardant non-woven tape Technical field The invention relates to a production process of a flame-retardant non-woven fabric, in particular to a production process of a flame-retardant non-woven fabric tape suitable for manufacturing wires and cables. Background technique Flame-retardant non-woven fabric is a kind of flame-retardant material commonly used in wires and cables. The flame-retardant non-woven fabrics used in China currently use powdered alumina, magnesium hydroxide, molybdenum oxide, iron oxide, and oxide Silicon, antimony trioxide, chloroethyl phosphate, organic halide, tetrabromobisphenol, decabromodiphenyl ether, red phosphorus, etc., have poor flame retardant effect, low oxygen index, and their thickness and specificity are large. The effects and economic benefits are not satisfactory. Summary of the invention The purpose of the present invention is to provide a non-woven fabric belt with good flame retardancy, small thickness and l...
