Problems solved by technology

[0002] In the production process of the existing tackifying masterbatch production process, the feeding amount of viscous functional additives is unstable, which leads to unstable viscosity of the viscous protective film. When the ambient temperature of the surface to be protected has a relatively large temperature change, the protective film is easy to Natural warping and detachment, loss of protection
The high-viscosity protective film produced by the existing protective film masterbatch has the problem of insufficient viscosity, or sufficient viscosity but there is residue, or it is not easy to tear off from the protected surface

Abstract

The invention creatively provides a method for preparing a residue-free high-viscosity protection membrane tackifying master batch. The master batch is prepared from the following raw materials in percentage by weight: 10-30% of low-molecular-weight polyisobutylene of which the molecular weight is 600-5000, 10-40% of high-molecular-weight polyisobutylene of which the molecular weight is 40000-800000, 10-30% of a thermoplastic elastomer and 0.1-3% of an antioxidant, wherein the total weight percentage of the low-molecular-weight polyisobutylene and the high-molecular-weight polyisobutylene is 50-70%. The viscous master batch is applied to a high-viscosity protection membrane, and is stable in viscosity, wide in temperature applicability and free of residue.

Description

technical field [0001] The invention relates to the technical field of organic chemistry, in particular to a method for preparing a non-residual high-viscosity protective film tackifier masterbatch. Background technique [0002] In the production process of the existing tackifying masterbatch production process, the feeding amount of viscous functional additives is unstable, which leads to unstable viscosity of the viscous protective film. When the ambient temperature of the surface to be protected has a relatively large temperature change, the protective film is easy to Naturally tilted and detached, losing its protective effect. The high-viscosity protective film produced by the existing protective film masterbatch has the problem that the viscosity is not enough, or the viscosity is sufficient but there is residue, or the problem that it is not easy to be torn off from the surface to be protected. Contents of the invention [0003] The problem to be solved by the inven...
