[0023] As introduced in the background technology, the artificial leather with a relatively small thickness in the prior art tends to have the problem of surface penetration in the actual production, thus failing to meet the requirements of customers. The inventor of the present application studies on the above-mentioned problem, has proposed a kind of preparation method of artificial leather, as figure 1 As shown, the preparation method comprises the following steps: coating the adhesive on the base cloth, and setting the artificial leather bottom layer and the artificial leather surface layer on the base cloth to obtain a pre-foamed composite layer; performing foaming treatment on the pre-foamed composite layer , to obtain artificial leather, and the foaming rate of foaming treatment is 1.5-2.5.
[0024] In the preparation method of above-mentioned artificial leather of the present invention, because the foaming rate of foaming treatment is 1.5~2.5, compared with prior art, ...
Embodiment 1
[0040] The preparation method of the artificial leather provided by the present embodiment comprises the following steps:
[0041] Utilize the polyvinyl chloride resin of 100 weight parts, the plasticizer of 35 weight parts and the blowing agent of 10 weight parts to prepare the artificial leather bottom layer that thickness is 0.2mm, wherein, plasticizer comprises dioctyl phthalate and Soybean oil, the weight portion of dioctyl phthalate is 25, the weight portion of soybean oil is 10, and the foaming agent is azodicarbonamide;
[0042] Utilize the polyvinyl chloride resin of 100 weight parts and the plasticizer of 35 weight parts to prepare artificial leather surface layer, wherein, plasticizer comprises dioctyl phthalate and soybean oil, and the weight part of dioctyl phthalate is 25, the weight portion of soybean oil is 10;
[0043] Coating PVC slurry on the base cloth as an adhesive, and setting the above-mentioned artificial leather bottom layer and the above-mentioned a...
Embodiment 2
[0046] The difference between the artificial leather provided by the present embodiment and embodiment 1 is:
[0047] Utilize the polyvinyl chloride resin of 100 parts by weight, the dioctyl phthalate of 30 parts by weight, the soybean oil of 10 parts by weight and the blowing agent of 3 parts by weight to prepare the artificial leather bottom layer that thickness is 0.13mm, utilize 100 parts by weight The polyvinyl chloride resin, the dioctyl phthalate of 38 parts by weight and the soybean oil of 2 parts by weight prepare the artificial leather surface layer, and the foaming rate of foaming treatment is 2.5.

Abstract
The invention provides artificial leather and a preparation method of the artificial leather. The preparation method comprises the following steps: S1, coating base cloth with an adhesive, and arranging an artificial leather bottom layer and an artificial leather surface layer on the base cloth, thus obtaining a pre-foaming composite layer; S2, carrying out foaming treatment on the pre-foaming composite layer, thus preparing the artificial leather, wherein the foaming rate of the foaming treatment is 1.5 to 2.5. According to the preparation method of the artificial leather, provided by the invention, the foaming rate of the foaming treatment is 1.5 to 2.5, compared with the prior art, the foaming rate is reduced by about 10 to 30 percent, and the volume ratio of PVC (Polyvinyl Chloride) in the artificial leather is increased by reducing the foaming rate, so that when printing ink is utilized for coloring the surface of the artificial leather, the printing ink located on the surface permeates the artificial leather from top to bottom, more printing ink is reserved in the PVC, the probability that the printing ink permeates to the base cloth of the artificial leather is further reduced, and the problem of surface syrup permeation when the prepared artificial leather is thinner is effectively improved.
Description
technical field [0001] The invention relates to the field of material technology, in particular to an artificial leather and a method for preparing the artificial leather. Background technique [0002] Leather is used as an interior material in various fields including the automobile industry. Leather generally includes natural leather and artificial leather. Among them, artificial leather is currently widely used in fields such as the automobile industry because it is cheaper than natural leather and is easy to mass-produce. middle. [0003] In the preparation process of artificial leather, the surface layer and the bottom layer are usually prepared first, and then the adhesive slurry such as PVC is coated on the base cloth, and then the bottom layer is calendered first, and the bottom layer is melted while it is hot from the calender roll. Lay it on the bottom cloth in the same way, and then paste the calendered surface layer film in the same way, and finally foam the pro...
