Problems solved by technology

Ordinary nylon TPU material has poor flame retardancy, and it is easy to produce molten droplets during combustion, and the burning time after leaving the fire is long
However, the current high flame-retardant nylon TPU composite material simply uses flame-retardant TPU resin, which has high cost, low transparency of TPU film, and unsatisfactory flame-retardant effect, especially for thinner nylon TPU composite materials. Both flame retardancy and peel strength cannot fully meet customer requirements
In addition, the direct purchase of flame retardant treated nylon base cloth is costly and the flame retardant level of the nylon base cloth cannot be controlled, which has a certain impact on the composite of nylon base cloth and TPU, and the peel strength of the prepared nylon TPU composite material is not good.

Abstract

The invention discloses a preparation method of a modified nylon base cloth. The preparation method of the modified nylon base cloth comprises the following steps: 1, coating solution preparation: adding a fire retardant to a solvent, and uniformly stirring, wherein the fire retardant is a cyclic phosphate compound; 2, carrying out nylon base cloth coating processing; and 3, drying: heating the nylon base cloth with a coating obtained in step 2 in a gradient manner for drying in order to obtain the modified nylon base cloth. The modified nylon base cloth is bonded to a TPU film to obtain a nylon TPU composite material. The modified nylon base cloth has the advantages of adjustment of the fire retardation level by adjusting a ratio of the fire retardant to the solvent, formula adjustment as required, production convenience, easy control of the production cost, and improvement of the peeling strength between the nylon base cloth and the TPUF film in a late stage. The nylon TUP composite material prepared by using the modified nylon base cloth has the advantages of low cost, good fire retardation property, good peeling strength, increased surface smoothness and increased surface soiling resistance.

Description

technical field [0001] The invention relates to a nylon base cloth and a TPU composite material, in particular to a modified nylon base cloth, a nylon TPU composite material and a preparation method for both. Background technique [0002] TPU (thermoplastic polyurethane elastomer rubber) material has the advantages of wear resistance, oil resistance, transparency and good elasticity, and is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Nylon TPU material is obtained by compounding nylon cloth and TPU film. Ordinary nylon TPU material has poor flame retardancy, and it is easy to produce molten droplets during combustion, and it takes a long time to continue burning away from the fire. However, the current high flame-retardant nylon TPU composite material simply uses flame-retardant TPU resin, which has high cost, low transparency of TPU film, and unsatisfactory flame-retardant effect, especially for thinner nylon TPU composite...
