Technical Field

The invention relates to the field of related products of cloth liner, in particular to a preparation method of high-strength ultrathin polyester cloth liner.

Background

With the rising and vigorous development of the automobile industry, the quality requirements of people on rubber tires are higher and higher. In the process of manufacturing tires, a cloth liner is usually used to divide rubber material placed in a roll, and in the rubber processing process, the cloth liner is used to preserve unvulcanized rubber material or cord fabric coated with rubber so as to keep the rubber surface fresh and avoid dust pollution. Coated fabrics are commonly used in tire floorings and are often used in relatively harsh environments, which requires that the coated fabrics have high temperature resistance.

However, the existing polyester laying cloth has low high temperature resistance, so that the service life is reduced, and the existing polyester laying cloth has defect.

Disclosure of Invention

The invention aims to provide a preparation method of a high-strength ultrathin polyester cloth liner, which aims to solve the problems that the conventional polyester cloth liner proposed in the background art has low high-temperature resistance, reduced service life and defects.

In order to achieve the purpose, the invention provides the following technical scheme: a preparation method of high-strength ultrathin polyester laying cloth comprises the following steps:

selecting PTA5-10 parts of phthalic acid, EG6-9 parts of ethylene glycol, 2-4 parts of catalyst and 2-5 parts of boehmite as polyester raw materials:

step two, carrying out esterification reaction and polycondensation reaction on the polyester raw material in the step one, and extruding the polyester raw material through a melt pump after the reaction is finished;

thirdly, granulating and drying the extruded polyester raw material to obtain the flame-retardant polyester;

selecting a glass fiber fabric as a base material, and performing edge covering through a weaving process;

putting the flame-retardant polyester prepared in the step three and the glass fiber fabric into a mixer for blending;

step six, hanging and airing the glass fiber fabric uniformly mixed in the step five to enable the glass fiber fabric to be naturally air-dried;

and step seven, inspecting the coated fabric air-dried in the step six, and packaging after the coated fabric is qualified.

Preferably, in the first step, PTA5 parts, ethylene glycol EG6 parts, 4 parts of catalyst and 5 parts of boehmite are selected as polyester raw materials.

Preferably, in the third step, the drying is carried out by selecting an electric heating baking oven.

Preferably, the four-way process is performed by long silk threads, and the glass fiber fabric is subjected to edge covering.

Compared with the prior art, the invention has the beneficial effects that:

according to the preparation method of the high-strength ultrathin polyester cloth liner, the phthalic acid, the ethylene glycol, the catalyst and the boehmite are used as the polyester raw materials, so that the high-strength ultrathin polyester cloth liner has good mechanical property and heat resistance, the glass fiber is selected as the base material, the fireproof performance is more excellent, the high-temperature resistance of the high-strength ultrathin polyester cloth liner is improved, the high-temperature resistance of the cloth liner is more excellent through the mutual combination of the glass fiber and the flame-retardant polyester, and the flame-retardant strength is higher.
