Masterbatch for tyre isolating membrane

Abstract

The invention discloses masterbatch for a tyre isolating membrane. The masterbatch comprises the following components in percentage by weight: 20% of ethylene bis stearamide, 5% of polyethylene wax, 10% of talcum powder, 5% of an antistatic agent, 3% of a coupling agent, 3% of zinc stearate, 40% of polyethylene TN26 and 14% of titanium dioxide. By adding ethylene bis stearamide and the antistatic agent, the adhesion is reduced, and the tyre isolating membrane prepared by adding the masterbatch is free of tyre adhesion and color transfer and has relatively high popularizing and using value.

Description

Technical field [0001] The invention relates to the field of preparation of plastic products, in particular to a master batch of tire isolation film. Background technique [0002] In the mass production of tires, isolation membranes are generally used for isolation after tires are off the assembly line. However, the use of ordinary polyethylene isolation film for isolation is prone to sticky tires and color migration. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a master batch of tire isolation film. [0004] To achieve the above objective, the technical scheme of the present invention is as follows: [0005] A tire isolation film masterbatch, the weight percentage of each component is: 20% ethylene bis-stearamide, 5% polyethylene wax, 10% talc, 5% antistatic agent, 3% coupling agent, hard Zinc fatty acid 3%, polyethylene TN2640%, titanium dioxide 14%. [0006] Ethylene bis-steara...
