Problems solved by technology

However, due to the disadvantages of PVC, such as poor environmental protection, poor folding resistance and easy cracking, PVC artificial leather can only be used on the side and back of the car seat, which greatly limits its application.
At present, the PVC artificial leather produced by the existing domestic technology has insufficient environmental performance and folding resistance to meet its needs as the main material for car seats.

Embodiment 1

[0030] Step 1, coating processing. It includes the following procedures:

[0031] Process 1, release paper preparation.

[0032] Step two, surface coating. In terms of percentage by weight, the raw materials of the following components: 55% PVC resin, 35% plasticizer, 4% flame retardant, 3% pigment, and 3% additive A are configured into a surface layer slurry, and the surface layer slurry is scraped by a scraper Apply it on the release paper to form a uniform thin layer, dry it, the solvent will be volatilized by heat, and form a thin film on the release paper, that is, the surface layer 2.

[0033] Step three, foam layer coating. In terms of weight percentage, the raw materials of the following components: 45% PVC resin, 45% plasticizer, 7% flame retardant, 2% pigment, 1% additive B, are configured into a foam layer slurry, and the foam layer is formed by a scraper. The foam layer slurry is scraped on the surface layer 2 described in the second step, and then dried and fo...

Abstract

The invention discloses an environment-friendly folding-resistant PVC artificial leather and a preparation method thereof. The environment-friendly folding-resistant PVC artificial leather comprises asurface treatment layer (1), a surface layer (2) bonded with the surface treatment layer (1), a foaming layer bonded with the surface layer (2), an adhesive layer (4) bonded with the foaming layer (3) and a low-elasticity base fabric (5) bonded with the adhesive layer (4). The environment-friendly and folding-resistant PVC artificial leather is prepared through a coating method. The method comprises the following steps of step 1, coating processing; step 2, drying and deodorizing; step 3, surface treatment; step 4, vacuum stripe suction. According to the method, by selecting an environment-friendly raw material capable of improving the strength of the artificial leather and controlling the content of each component in the raw material, the environmental friendliness and folding-resistanceof the PVC artificial leather are enhanced, so that the PVC artificial leather can replace a PU synthetic leather as a main material of automobile seats.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to an environment-friendly folding-resistant PVC artificial leather and a preparation method thereof. Background technique [0002] Due to lower cost and ease of processing, PVC artificial leather is widely used in home decoration and various automotive interior applications. However, due to the poor environmental protection of PVC and the disadvantages of being easily cracked and not foldable, PVC artificial leather can only be used on the side and back of the car seat, which greatly limits its application. At present, the PVC artificial leather produced by the existing domestic technology has not enough environmental protection performance and folding resistance to meet its demand as the main material of car seats. Contents of the invention [0003] The object of the present invention is to aim at the above-mentioned defect in the prior art, provide a kind of environ...
