Problems solved by technology

[0005] The above-mentioned patents all use non-woven fabrics of traditional thickness to obtain flame retardancy, heat insulation and air permeability, but none of them can achieve high-efficiency flame retardancy
However, research and development of thin flame-retardant non-woven fabrics with high bonding strength, high flame retardancy, and low cost are relatively rare, and traditional thin non-woven fabrics cannot achieve flame-retardant effects.

Embodiment 1

[0022] The first step, the preparation of base cloth

[0023] Polyester fibers are formed by opening, carding, net laying, and needle punching, and then viscose fibers are laid on the upper layer and the two are needle punched to form a base fabric. , so that the polyester fibers are evenly and firmly connected together. The total weight of the base cloth is 100-120g / m 2 , and the weight percentage of polyester fiber is 80-95%, and the weight percentage of viscose fiber is 5-20%.

[0024] The second step, dipping

[0025] The flame retardant and the water-based glue are uniformly mixed to form the flame-retardant glue, wherein the weight percentage of the water-based glue is 40-60%, and the weight percentage of the flame retardant is 40-60%. The flame retardant glue is mixed with color paste and water to obtain an impregnating liquid, and the base cloth obtained by acupuncture is soaked in the impregnating liquid, and after impregnated, it is rolled by a hot roller to remov...

Embodiment 2

[0033] The first step, the preparation of base cloth

[0034] Polyester fibers are formed by opening, carding, net laying, and needle punching, and then viscose fibers are laid on the upper layer and the two are needle punched to form a base fabric. , so that the polyester fibers are evenly and firmly connected together. The total weight of the base cloth is 100-120g / m 2 , and the weight percentage of polyester fiber is 60-80%, and the weight percentage of viscose fiber is 20-40%.

[0035] The second step, dipping

[0036] The flame retardant and the water-based glue are uniformly mixed to form the flame-retardant glue, wherein the weight percentage of the water-based glue is 40-60%, and the weight percentage of the flame retardant is 40-60%. The flame retardant glue is mixed with color paste and water to obtain an impregnating liquid, and the base cloth obtained by acupuncture is soaked in the impregnating liquid, and after impregnated, it is rolled by a hot roller to remo...

Embodiment 1

[0043] The comparison of the experimental results of the optimal process ratio of embodiment 1 and embodiment 2 shows that although the amount of flame retardant in the impregnation solution of experiment 7 of embodiment 1 is less than that of experiment 6 of embodiment 2, the mixed powder particles sprinkled The content of polyethersulfone resin is higher. Due to the good viscosity and internal cohesion of polyethersulfone resin, the powder particles of polyethersulfone resin are used to improve the bonding force between the base fabric and aluminum foil, glass fiber, and foam, and polyethersulfone resin is also self-extinguishing, without adding any Flame retardants have excellent flame retardancy, so the nonwoven fabric obtained in Example 1 has high flame retardancy. On the contrary, the content of polyethersulfone resin in the mixed powder particles in Experiment 7 of Example 2 is relatively low, but the content of flame retardant in the impregnation solution is relativel...

Abstract

The invention discloses a preparation method for a thin flame-retardant non-woven fabric applied to vehicles. The preparation method comprises the following steps: compounding polyester fibers and viscose fibers in a needling manner so as to form a base fabric; uniformly mixing a flame retardant and water-based glue to form a flame-retardant adhesive, and mixing the flame-retardant adhesive with black color paste and water to obtain an impregnation solution; soaking the base fabric obtained after needling in the impregnation solution; and spraying powder particles on the impregnated base fabric so as to obtain the flame-retardant non-woven fabric with a gram weight of 100 to 150 g / m<2>, wherein the powder particles are a mixture of the powder particles of polyethersulfone resin and phenolic resin. Compared with conventional flame-retardant non-woven fabrics, the flame-retardant non-woven fabric of the invention is reduced in thickness, saves materials and lowered in production cost, and achieves good flame retardant effect at the same time.

Description

technical field [0001] The invention relates to the application field of automotive interior materials, in particular to a method for preparing a thin flame-retardant non-woven fabric for vehicles. Background technique [0002] In recent years, automobile combustion safety accidents have occurred frequently, and various countries have clear regulations on the flammability of automotive interior fabrics. The development, application and promotion of flame-retardant automotive interior fabrics has become the general trend. For flame-retardant non-woven fabrics used in vehicles, in addition to flame-retardant requirements, it is also expected to achieve the desired effect while saving costs. It is often impossible to achieve the ideal effect of flame retardancy by using the traditional non-woven fabric manufacturing process. [0003] The invention with the application number CN201410062384.X relates to a flame-retardant non-woven fabric. The flame-retardant non-woven fabric is...
