Abstract

The invention discloses a lost foam cast alloy steel coating and a preparation method thereof and relates to the technical field of coatings. The lost foam cast alloy steel coating comprises the following raw materials in percentage by mass: 50-60 parts of zircon sand, 2-6 parts of bentonite, 2-4 parts of carboxymethyl cellulose, 1-3 parts of a white emulsion, 3-5 parts of silica gel, 2-4 parts ofa resin, 3-5 parts of ethylene glycol, 1-2 parts of attapuigite clay, 10-20 parts of n-butyl alcohol and 2-4 parts of casein. According to the lost foam cast alloy steel coating and the preparation method thereof, due to adoption of the zircon sand, the adsorption of the coating can be further improved; due to adoption of the silica gel, the adsorption and the flame retardancy of the coating canbe improved; due to adoption of the resin, a cast part can be well protected, and the wearing resistance of the cast part can be improved; and due to adoption of the attapuigite clay, functions of sterilization, deodorization, detoxication and insecticiding properties can be achieved, the cast part can be well protected, and the corrosion property of the cast part can be improved.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a lost foam casting alloy steel coating and a preparation method thereof. Background technique

[0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water.

[0003] Most of the lost foam casting alloy steel coatings are easy to flow on the surface of the model after being applied on the surface of the model, which will lead to uneven feeding of the coating and easily cause deformation of the casting, which will affect the overall quality of the casting. The adsorption force is poor, and Corrosion resistance is poor. Contents of the invention
