Abstract

The invention relates to the field of corrosion-proof ice-covering-proof coatings, and particularly relates to a corrosion-proof ice-covering-proof coating. The corrosion-proof ice-covering-proof coating comprises the following components in percentage by weight: 15%-30% of epoxy resin, 10%-15% of fluoroolefin resin, 15%-40% of nanometer silicon oxide, 10%-20% of solidifying agents, 1%-5% of toughening resin, 5%-10% of titanium dioxide blending agents, 15%-30% of fluorinated acrylate modified polyurethane resin and 5%-15% of organic solvents, wherein each titanium dioxide blending agent comprises polyurethane, biuret, polyester J4, butyl alcohol, ethanol ethyl ester, petroleum type dimethyl benzene, titanium dioxide, fine particle calcium carbonate, talcum powder, sodium pentachlorophenate and tri-butyl alcohol, and the weight ratio of polyurethane to biuret to polyester J4 to butyl alcohol to ethanol ethyl ester to petroleum type dimethyl benzene to titanium dioxide to fine particle calcium carbonate to talcum powder to sodium pentachlorophenate to tri-butyl alcohol is (1.5-2.5):(1-2):(1.5-2):(1.5-2):(1-1.5):(2-2.5):(1.5-2):(1-2):(1-1.5):(0.1-0.3):(0.3-0.5). The corrosion-proof ice-covering-proof coating disclosed by the invention has good adhesive force, can meet the requirements for use conditions of an oil drill rod in a using process in a cold place, and has the advantages of acid resistance, alkali resistance, corrosion proofing and ice-covering proofing.

Description

technical field [0001] The invention relates to the field of anti-corrosion and anti-icing coatings, in particular to an anti-corrosion and anti-icing coating. Background technique [0002] Paint is a chemical mixture that can firmly cover the surface of an object for protection, decoration, marking and other special purposes. It is an anti-corrosion and anti-icing coating. An authoritative book "An Anti-corrosion and Anti-icing Coating Technology" in the field of anti-corrosion and anti-icing coating in China is defined as follows: "An anti-corrosion and anti-icing coating is a kind of material. The material can be coated on the surface of the object by different construction techniques to form a solid film with firm adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." Belongs to organic chemical polymer materials , the formed coating film belongs to the polymer compound type. ...
