Paste water-based isolation agent, preparation method and application method thereof

Abstract

The invention discloses a paste water-based isolation agent, a preparation method and an application method thereof thereof. The paste water-based isolation agent comprises the following components by mass: 3-5 parts of an inorganic powder additive, 0.1-1.0 part of an anionic surfactant, 0.5-5.5 parts of a nonionic surfactant, 5-10 parts of a thixotropic agent, 0.2-2.0 parts of a thickener, 0.1-0.5 part of a defoaming agent, and 60-100 parts of deionized water. The preparation method consists of: mixing water with the surfactants, conducting stirring dissolving, adding the inorganic powder additive, and adding the defoaming agent dropwise, adding the thixotropic agent and thickener in batches, stirring the materials fully, and performing grinding to a homogeneous phase, thus obtaining the isolation agent. And the application method includes: during use, preparing the isolation agent into a water solution according to a mass ratio of 1:3-15, adding the water solution into a water cooling groove of a rubber slice to realize isolation agent coating at the same time of water cooling, and then carrying out rod hanging drying and stacking. The paste water-based isolation agent provided by the invention has the advantages of easy water dissolution, no toxicity, no smell, simple process and low cost, and almost has no effect on the subsequent processing performance of rubber.

Description

technical field [0001] The invention relates to a paste-like water-based rubber release agent, in particular to one used to prevent natural rubber, synthetic rubber and their blended rubbers from sticking during storage and transportation after mastication, mixing or final kneading. The preparation method and application method of the pasty water-based rubber release agent. Background technique [0002] In the production and processing process of rubber products, the rubber material is stacked and parked after kneading or banburying. Due to the high self-adhesiveness of the film, and under the action of layer-by-layer pressure, the film is prone to layer-by-layer adhesion, which seriously affects subsequent processing and use. Therefore, before the rubber is transported and stacked for storage, polyethylene plastic film or a layer of release agent is used on the film to achieve isolation and prevent the films from sticking to each other. Due to the mixing of polyethylene f...
