Abstract
The invention relates to a high-elasticity polyvinyl chloride (PVC) synthetic leather and a production method thereof. The synthetic leather is combined by three layers, wherein the base material is cloth, the middle layer is made from foaming PVC, and the upper layer is made from non-foaming PVC. The middle layer comprises the following components in parts by weight: 60-80 parts of PVC1, 20-40 parts of PVC2, 65-90 parts of DOP, 80-120 parts of calcium carbonate, 2-3.5 parts of foaming stabilizer, 5-9 parts of AC foaming agent and 4-6 parts of pigment. The upper layer comprises the following components in parts by weight: 60-80 parts of PVC1, 20-40 parts of PVC2, 65-90 parts of DOP, 10-20 parts of calcium carbonate, 2-3.5 parts of stabilizer and 6-8 parts of pigment, wherein the PVC1 and PVC2 are PVCs with different polymerization degrees, the type of the PVC1 is S-70 and the type of the PVC2 is HS-200. The production method of the synthetic leather comprises the following steps: mixing the raw materials, plasticizing, performing open mixing, laminating, foaming, and treating to obtain the finished product. Each technical index of the finished product meets the requirement of the relevant regulation and is characterized by having the similar hand feeling of the real feather. The synthetic leather of the invention is beneficial for the product promotion and suitable for large scale production and processing.
