Preparation method of rubber coating

Abstract

The invention discloses a preparation method of a rubber coating. The rubber coating is characterized in that the rubber coating is prepared by independently preparing a component A and a component B and finally mixing; the component A contains rubber, fillers and accessory ingredients; the preparation process comprises the following steps: firstly, mixing raw materials in the component A uniformly with an internal mixer, discharging slices with an open mill, cutting the materials by using a material cutting machine, then melting the rubber, adding a defoaming agent and a flatting agent, grinding and filtering for multiple times. The component B comprises raw rubber, fillers and a rubber accelerant; the preparation process comprises the following steps: plasticating the raw materials in the component B with the open mill, thinning and discharging slices, cutting the materials by using the material cutting machine, melting the rubber and filtering for multiple times; then mixing rubber slurry of the component A and the component B uniformly, standing and defoaming, and thus preparing the rubber coating. The rubber coating is mixed uniformly; the quality and the color are easily controllable, so that the rubber coating is suitable for flow production and long-term storage, and the fineness of the coating and the flatting of the coating are not affected.

Description

Technical field [0001] The invention relates to the technical field of rubber materials, in particular to a method for preparing rubber coatings. Background technique [0002] At present, the commonly used method for preparing rubber coatings is to mix the filler and rubber without passing through a dense or open mill, and directly put the powder, additives, and rubber into the sol kettle to add a solvent for dissolution. Although the method is simple, but due to the lack of rubber In the process of high-speed shearing and mixing of accessories and banburying and plasticization, the rubber and accessories are not uniformly mixed, the coating is easy to layer, and the summer configuration is prone to gel phenomenon, and the color of the coating is difficult to control, and the configuration temperature is strict. It is not suitable for flow operation and long-term storage; in addition, the rubber coating that has not been sanded or filtered has certain impurities, which affects th...

Problems solved by technology

[0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, and provide a kind of preparation method of rubber paint, mainly solve existing rubber paint mixing inhomogeneous, easy delamination, easy to produce gel phenomenon, color is more difficult to control, not easy It is suitable for flow operation and long-term storage, and it will affect the fineness of the coating and the smoothness of the coating, etc.
