Abstract

The invention discloses a paste-like water-based rubber release agent and its preparation method and application method. Its components include 3-15 parts of inorganic powder additives, 0.1-1.0 parts of anionic surfactant, and 0.5-1.0 parts of anionic surfactant in parts by mass. 5.5 parts of nonionic surfactant, 5-10 parts of thixotropic agent, 0.2-2.0 parts of thickener, 0.1-0.5 parts of defoamer, 60-100 parts of deionized water. Mix water and surfactant, stir to dissolve, add inorganic powder additives, add defoamer dropwise, add thixotropic agent and thickener in batches, stir well and grind until homogeneous to obtain the release agent. When in use, make an aqueous solution at a mass ratio of 1:3 to 15, add it to the water cooling tank of the film, the film is cooled by water while the release agent is applied, and it can be stacked after air drying on the hanging rod. The invention is easily soluble in water, non-toxic, tasteless, simple in process and low in cost, and basically has no influence 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...
