Abstract

The invention relates to an interpenetrating polymer network anti-corrosive paint and a manufacturing method thereof. The paint is made of the raw materials based on the parts by weight: 20-50 parts of alkyd resin, 5-20 parts of phenolic resin, 10-40 parts of epoxide resin, 5-30 parts of cross-linking agent, 5-15 parts of phthalic anhydride, and 0.3-1 part of catalyst. In the manufacturing method, the alkyd resin, the phenolic resin and the epoxide resin are taken as interpenetrating polymer network resin, and the benzoic anhydride, the vulcabond and the amine resin are taken as cross linker. First, the alkyd resin is penetrated with the phenolic resin for a first cross bonding by using the cross linker; then, the obtained resin is penetrated with the epoxide resin for a second cross bonding by using the cross linker; at last, the synthetic resin with excellent combination property can be synthesized, and the anti-corrosive paint having high performance can be prepared.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an anti-corrosion coating and a manufacturing method manufactured by using interpenetrating network technology for multiple cross-linking methods. Background technique [0002] Interpenetrating Polymer Network (IPN) is a novel polymer alloy with special properties formed by the tight permanent entanglement and interpenetration of two or more polymer networks. Its characteristic is that one material randomly penetrates into another material, which plays the role of "forced compatibility" and "synergistic effect". The polymer component still retains its original structure, and it is compatible with other substances. Fusion together, so that the material does not lose the inherent characteristics of the original polymer, but also can obtain the unique properties that cannot be obtained by other blended polymers. It is a rapidly developing modified material with excellent comprehensi...
