Problems solved by technology

[0004] The present invention provides a sealing and protective rubber coating and a preparation method thereof, which can effectively solve the problem that the weather resistance and adhesion of the rubber coating proposed in the above-mentioned background technology are average, and the hardness of the paint film is low, and the performance of the rubber coating declines rapidly in open-air corrosive environments. As a result, the sealing protection period is short, which limits its practical application. At the same time, during the powder addition process during the production of rubber coatings, the powder is easy to adhere to the inner wall of the reaction tank, and at the same time, the raw materials cannot be mixed during the mixing process. Efficient stirring, which leads to slow mixing between raw materials and reduces the production efficiency of coatings

Abstract

The invention discloses a sealing protection rubber coating material and a preparation method thereof. The preparation method comprises the following steps: material preparing, wherein raw materials needing to be used are selected and weighed according to production targets, and are carried to the side of a reaction tank for addition in a subsequent production process; and soaking mixing, wherein chlorosulfonated polyethylene, a chlorinated rubber, a styrene elastomer, a dispersing agent and a solvent are added into the reaction tank and soaked for 12 hours, and then stirring is conducted for 30-50 minutes at a speed of 600-800 r / min. According to the invention, the chlorosulfonated polyethylene, the chlorinated rubber and the styrene elastomer are mixed for modification, so that the sealing protection effect and the adhesive force are improved; and the ceramic whiskers, the carbon nanotubes, the ceramic powder and the ceramic whiskers effectively improve the corrosion resistance of the coating and improve the toughness, hardness and scratch resistance of the coating, and the aluminum paste effectively improves the weather resistance of the coating, so that the sealing protection coating with excellent comprehensive performance is formed.

Description

technical field [0001] The invention relates to the technical field of rubber coatings, in particular to a sealing and protective rubber coating and a preparation method thereof. Background technique [0002] Rubber coating is a type of coating with natural rubber derivatives or synthetic rubber as the main film-forming substance. It is sprayed on the surface of the object and is in a matte or semi-matte state. It feels very delicate and smooth, and has an elegant and solemn appearance. Natural rubber derivatives Mainly chlorinated rubber, cyclized rubber, etc. Synthetic rubber mainly includes styrene-butadiene, neoprene, polysulfide, nitrile and other rubber varieties, among which chlorinated rubber is more, especially neoprene is more important; [0003] However, at present, the weather resistance and adhesion of rubber coatings are average, and the hardness of the paint film is low. In the open-air corrosive environment, the performance of various aspects decreases rapidl...
