Embodiment 1

[0016] Example 1: High-elastic PVC synthetic leather, with raised cloth as the base material: first, the middle layer material is weighed according to the component formula, mixed by a high-speed mixer, pre-plasticized for 300~500S, and then added to an internal mixer for Mixing and plasticizing are monitored by the controller of the internal mixer. The plasticizing time is 430~500S and the temperature is 140~160℃. Paste on the base material, the temperature of the four rollers of the tape machine is 190~200°C for the front wheel; 185~195°C for the upper wheel; 180~190°C for the middle wheel; 175~185°C for the lower wheel; 1. After the upper layer material is measured according to the component formula, operate according to the first step method, the upper layer material is pasted on the middle layer, the plasticizing time is 460~550S, and the speed is 40~50M / min; The semi-finished products are foamed in the foaming furnace. The foaming parameters are 120~140℃ for one box; 180...

Embodiment 2

[0017] Embodiment 2: The high-grade sports shoe upper material uses knitted cloth as the base material, and the production method is the same as that of Embodiment 1.

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.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-elastic PVC synthetic leather and a production method thereof. Background technique [0002] We know that high-grade handbag fabrics are generally made of genuine leather, but the cost of genuine leather is high and the style is monotonous, which is not conducive to product promotion. Contents of the invention [0003] The purpose of the present invention is to develop a high-elastic PVC synthetic leather with a hand feeling similar to genuine leather, relatively low in cost, and rich in styles. [0004] The technical problem to be solved by the present invention is to seek a reasonable formula so that the product feels similar to real leather, and at the same time, it is easy to process in mass production. [0005] In the present invention, the high-elastic PVC synthetic leather is composed of three layers, the base material is cloth, the middle layer is foam...
