Abstract

The invention discloses a mutually perforating network high anticorrosion primer and a preparation method. Eighteen types of raw materials, such as first tung oil, first rosin, 424<#>, refined castor oil, polyester chips, xylene, cellulose, butyl acetate, aluminum triphosphate, green silicon carbide, various pigments, and the like, are used to result in the IPN stereo chemical structure of a product through technological processes of melting, alcoholysis, esterification, diluting, high speed decomposition, sand milling, filtration, etc. The deficiency that the anticorrosion performance of the present primer is not ideal is overcome. Specific high anticorrosion performance is provided. A coated film is provided with no changes after being immersed in 30 percent of phosphoric acid solution, 5 percent of salt water and xylene solution for 10000h. Permanently applied to the environment of under 200 DEG C, the primer is characterized in that the flexibility is smaller than 1mm, the hardness reaches to 3H, the surface adhesion reaches to 1 grade and the positive and reverse impact strength is 50kg.cm. With large expansion application value and considerable social and economical benefits, the primer can be used together with various topcoats and can be directly added with special thinner to be used for the construction.

Description

technical field [0001] The invention relates to chemical products and a preparation method thereof, in particular to an interpenetrating network high anticorrosion and antirust primer and a preparation method thereof. Background technique [0002] Various primers with anti-corrosion and anti-rust functions have been widely used in industries such as electromechanical equipment, motor vehicles and ships, instruments and meters, buildings, bridges, chemical equipment, oil field equipment, oil storage devices, and furniture. The primers currently available on the market have unsatisfactory anti-corrosion and anti-rust properties because they do not have an interpenetrating network (IPN) three-dimensional molecular structure. The technical content about interpenetrating network high anticorrosion antirust primer neither has report nor corresponding product comes out. Contents of the invention [0003] Aiming at the defects of above-mentioned various primers, the object of the...
