Abstract
The invention provides an environment protecting plastic rubber material and a preparation method of the plastic rubber material. The plastic rubber material is made of PVC resin powder, environment protecting plasticizer, ca-zn composite stabilizer, filler, and thermoplastic elastomer. The preparation method comprises the following steps: the PVC resin powder and the ca-zn composite stabilizer are mixed and heated by part by weight in a kneading machine, and the environment protecting plasticizer and the filler are added during temperature rising, and then all the materials are mixed and heated to be high temperature mixture. The high temperature mixture is cooled with the thermoplastic elastomer being added and mixed in a cold mixer. Environment protecting PVC particles are made and extruded in mold by an extruder. Because the environment protecting plasticizer is added into the PVC (polyvinyl chloride) plastic rubber material, the plastic rubber material is a PVC (polyvinyl chloride) plastic rubber material that can contacts the food and satisfy the requirement for exporting products, which can be applied in the products like fridges and freezers with great practicability.
