Problems solved by technology

[0003] At present, in the existing market, more ordinary polyurethane artificial leather technology is widely used. Its solid content is about 30%, and the solvent accounts for about 70%. Because of the large amount of solvent used and the large amount of solvent remaining, it is harmful to the human body. With the environment, the odor is relatively large

Embodiment 1

[0049] see figure 1 , a high wear-resistant PU artificial leather and its preparation process, comprising a main structure layer 6, the upper end of the main structure layer 6 is sequentially provided with a reinforcing wear-resistant layer 5, a wear-resistant layer 4, a surface layer 3, an anion layer 2 and a moisture-absorbing layer 1 The hygroscopic layer 1 and the anion layer 2 both use water-based polycarbonate, and protein material is added to the hygroscopic layer 1. After the water-based polycarbonate and the protein material are mixed, the hygroscopic layer 1 is endowed with a hygroscopic function, and the anion layer 2 Adding negative ion materials, water-based polycarbonate and negative ion materials are mixed, so that the negative ion layer 2 is endowed with the function of purifying the air. At the same time, the negative ion material in the negative ion layer 2 can eliminate free radicals, which has a good effect on human health. It can sterilize and deodorize. T...

Embodiment 2

[0054] A kind of preparation technology of high abrasion-resistant PU artificial leather described in embodiment 1, comprises the following steps:

[0055] The first step is to add protein raw materials into the water-based polycarbonate, and then mix the two to obtain the hygroscopic layer 1;

[0056] The second step is to add anion material to water-based polycarbonate, and then mix the two to obtain anion layer 2;

[0057] The third step, the surface layer 3 is treated with a water-based polycarbonate resin surface treatment agent;

[0058] The fourth step is to use polycarbonate resin and an environmentally friendly wear-resistant agent to eliminate air bubbles and improve the density through precision defoaming equipment to obtain a wear-resistant layer 4, thereby increasing wear resistance, and then setting a supplementary layer in the same way Strong wear-resistant layer 5;

[0059] The fifth step is to use a two-component polyether resin with a solid content of more ...

Abstract

The invention discloses high wear resistant PU artificial leather and a preparation technology thereof, and belongs to the field of artificial leather. The high wear resistant PU artificial leather comprises a main body structure layer, wherein a reinforced wear resistant layer, a wear resistant layer, a surface layer, a negative ion layer and a moisture absorption layer are arranged at the upperend of the main body structure layer in sequence, the reinforced wear resistant layer and the main body structure layer are connected, the end, away from the main body structure layer, of the reinforced wear resistant layer is connected with the wear resistance layer, the end, away from the reinforced wear resistant layer, of the wear resistant layer is connected with the surface layer, the end, away from the wear resistant layer, of the surface layer is connected with the negative ion layer, the end, away from the surface layer, of the negative ion layer is connected with the moisture absorption layer, and an adhesion layer and a base cloth layer are arranged under the main body structure layer in sequence. The effects of reducing solvent dosage and solvent residues can be achieved, so that harm of the PU artificial leather on human bodies and the environment is reduced, the PU artificial leather has a good smell and low VOC, and meanwhile, the PU artificial leather has functions of high wear resistance, moisture absorption, air permeability, inflaming retarding, high durability, air purification and the like.

Description

technical field [0001] The invention relates to the field of artificial leather, in particular to a high wear-resistant PU artificial leather and a preparation process thereof. Background technique [0002] PU artificial leather is the skin of polyurethane. It is widely used in the decoration of luggage, clothing, shoes, vehicles and furniture. It has been increasingly recognized by the market. Its wide application range, large quantity and variety are beyond the satisfaction of traditional natural leather. The quality of PU artificial leather is also good or bad, and good PU artificial leather is even more expensive than genuine leather. The variety developed in the early 1960s is made of raised cloth as the base and polyurethane solution as the coating. The raised cloth is impregnated with polyurethane solution, coated and solidified in a water bath to obtain a microporous layer, and after grinding, it becomes polyurethane suede leather. This kind of artificial leather ...
