preparation example Construction

[0023] The preparation method of this crease-resistant PVC rubber comprises the steps:

[0024] a. Put PVC powder, emulsifying powder and plasticizer into the mixer for pre-mixing according to parts by mass. The mixing time is 7-9 minutes and the temperature is 110-130°C. After pre-mixing, let the mixture stand for 8 hours;

[0025] b. Then add the remaining raw materials to the material in step a and carry out high-speed stirring at a speed of 850r / min. Stir for 5-7 minutes until the material reaches a dry and loose state, and then put it into a 10,000-horsepower machine for squeezing, and control the current of the 10,000-horsepower machine It is 200A, making it into a melted block rubber;

[0026] c. Put the melted block rubber material in step b into the two-roll mill to fully turn over the material to improve the mixing uniformity and gelation degree of the material, wherein the roller temperature of the primary refining roller of the two-roll mill is 160°C

Abstract

The invention discloses anti-crease PVC (polyvinyl chloride) rubber and a preparation method thereof. The anti-crease PVC rubber is prepared from the following raw materials in percentage by weight: 60 to 90 phr of PVC powder, 10 to 40 phr of emulsified powder, 20 to 120 phr of a plasticizer, 1 to 10 phr of a stabilizing agent, 0 to 10 phr of a modifier, 0 to 50 phr of a filler and 2 to 10 phr ofa foaming agent. On the premise of guaranteeing the characteristics of the rubber, the anti-crease PVC rubber disclosed by the invention has certain elasticity, so that no creases occur during use orwinding of the anti-crease PVC rubber, and the service life of the anti-crease PVC rubber is guaranteed.

Description

technical field [0001] The invention relates to a PVC rubber, in particular to a crease-resistant PVC rubber and a preparation method thereof. Background technique [0002] PVC leather is a plastic product that looks and feels like leather and can be used instead of it. The current PVC leather is a composite of cloth base and plastic. The slurry or film is compounded on the cloth base by coating or pressing. The surface of the composite is embossed or calendered for a leather-like pattern or sheen, printed or treated with special surface treatments to give it a more leather-like look and feel. PVC leather is similar to natural leather in appearance and some properties, but there is a big difference in other aspects, especially tear strength, air permeability, flexibility and hand feeling. Moreover, PVC leather is prone to wrinkles during installation, which affects the appearance. Therefore, how to improve the wrinkle resistance of PVC leather plays an extremely important r...
