Problems solved by technology

When preparing artificial leather whose foam layer is polyvinyl chloride foam layer, most of the existing adhesive materials are water-based acrylic adhesive materials. This adhesive material will not only produce peculiar smell, but also consume 160g per yard of artificial leather. Left and right, the peel strength of the artificial leather (referring to the peeling of the bottom layer, that is, the peeling of the base fabric layer and the foam layer) can only reach about 1kg / 30mm, and the quality is poor

Abstract

The invention relates to artificial leather with high peel strength and a preparation method thereof. The artificial leather comprises a surface layer, a foamed layer, a bonding layer and a base cloth layer, wherein the foamed layer is formed by drying PVC (Polyvinyl Chloride) foaming slurry; the bonding layer is formed by drying a PVC modified bonding material; the PVC modified bonding material consists of PVC resin, DOP (Dioctyl-Phthalate) and tetraisopropyl di(dioctyl phosphate acyloxy) titanate. The preparation method comprises the following steps of forming the surface layer, the PV foamed layer, the bonding layer and the base cloth layer on release paper in sequence, wherein the bonding layer is formed by drying the PVC modified bonding material, and the PVC modified bonding material is prepared by mixing PVC resin, DOP (Dioctyl-Phthalate) and tetraisopropyl di(dioctyl phosphate acyloxy) titanate; and removing the release paper to obtain the artificial leather. The artificial leather provided by the invention is free from peculiar smell, high in peel strength and low in production cost.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to an artificial leather with high peel strength and a preparation method thereof. Background technique [0002] The artificial leather currently produced usually includes a surface layer, a foam layer, an adhesive layer and a base cloth layer, and the preparation method is roughly as follows: [0003] Step 1, select base cloth and release paper, prepare surface layer slurry, foaming slurry and bonding material; [0004] Step 2. Coat the prepared surface layer slurry on the selected release paper, and form the surface layer after drying; [0005] Step 3, coating the prepared foaming slurry on the surface layer, and forming a foaming layer after foaming; [0006] Step 4, coating the prepared bonding material on the foam layer, then bonding the selected base cloth and drying to form an adhesive layer and a base cloth layer; [0007] Step 5, removing the release paper to ...
