A kind of production technology of chloroether blended rubber-plastic emulsion anti-corrosion coating

Abstract

The invention discloses a chloroether blended rubber-plastic emulsion anti-corrosion coating and a production process thereof. The invention belongs to the technical field of anti-corrosion coatings. The invention utilizes the thermal curing reaction of the blended rubber and plastic to form, or the paint is used alone as a powder coating for spraying. , spray the cured glue evenly on the surface of the paint, and roll it with a pressure roller to roll evenly to form a film and heat curing. It has good weather resistance, UV resistance, water resistance, and can be used with water-based epoxy or acrylic primers, Matching with middle paint, excellent corrosion resistance, excellent gloss and color retention, maintain oil resistance, aging resistance, ozone resistance and other properties of copolychloroether rubber, and also improve cold resistance, reduce compression deformation, and inhibit thermal aging. Soft ability, excellent adhesion on the surface of steel, concrete and other substrates, and the use of water as a solvent can greatly improve the safety of coatings during storage, transportation and construction, and can be used in architectural decoration, automotive , ships and, railways, aviation, bridges and wood coating, etc.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, in particular to a production process of a chloroether blended rubber-plastic emulsion anti-corrosion coating. Background technique [0002] Chloroether rubber is the abbreviation of chlorinated polyether rubber, which refers to the polyether rubber with chloromethyl group on the inverted chain, which used to be called chlorohydrin rubber in the past. Excellent comprehensive performance and promising development prospects. Chloroether rubber was developed and put on the market by the United States in the mid-1960s, and was successfully developed in Japan soon after that. Now the United States and Japan have been industrialized on a large scale and are widely used. There is a big gap between the development and application of chloroether rubber in my country and abroad. There are many types of polymer blends. Rubber-plastic blending refers to the blend of plastic and plastic or the blen...

Problems solved by technology

In order to ensure the beauty and prevent corrosion, it is necessary to use a large number of paints for beautification. To make people experience safer, it is necessary to work hard on environmental protection. Aiming at the disadvantages of traditional industrial paints such as inconvenient construction, high viscosity, and many organic solvents, environmental protection Coatings have been widely used. Traditional materials need to be dried for a long time during coating construction. This process will cause organic solvents to volatilize, waste resources and pollute the environment. There are many unsafe factors and the risk of fire hazards. The probability is quite high, and it will cause harm to the body of construction and users. Water-based coatings have completely replaced solvent-based products and are specially used in the construction of ship coating projects. Promotion and use are of great significance to future development. Currently, the market Most of the products are water-based chlorosulfonated polyethylene anti-corrosion coatings, water-based chloroether anti-corrosion coatings, water-based cyclovinyl ester anti-corrosion coatings, and the above coatings have poor weather resistance, easy powdering, poor ability to withstand strong corrosive media at high temperatures, and poor impact resistance. , excellent performance emulsion anti-corrosion coatings are mainly used in large-scale national defense underground projects, tunnel projects, subway projects, petrochemical, transportation, shipbuilding industries, as protective coating materials for non-metallic and metal structures, buildings, equipment, etc.
