Description

Excellent highly-chlorinated polyethylene composite coating of a kind of acid-resistant anti-corrosion and preparation method thereof
Technical field
The invention belongs to corrosion resistant coating field, and in particular to a kind of excellent highly-chlorinated polyethylene composite coating of acid-resistant anti-corrosion And preparation method thereof.
Background technology
Highly-chlorinated polyethylene chlorinty is high, also known as HCPE resins.White lightweight little particle, chlorinity>61%, thermal decomposition temperature Degree>130 DEG C, 180 DEG C of heat-stable time>3min.As double bond is not contained in molecular structure, chlorine atom is random again, therefore With good weatherability, ozone resistance, heat-resistant aging, flame resistance, chemical proofing and oil resistivity, but as single The coating of film forming matter is very crisp, adhesive force is poor, therefore usually adds flexible resin in actual application to improve film Performance, improves the weather resistance of film, while improving the physical and mechanical propertiess such as the adhesive force and gloss of film, such as adds alkyd tree Fat, acrylic resin, chlorinated paraffin etc. are modified.
Zhou Geng's Bin, Yang Zhuoru et al. are at which《The preparation of fluoro-acrylate copolymer and its film coated surface hydro-oleophobicity The research of energy》In one text, with monomers methyl methacrylate, butyl acrylate, acrylic acid, fluorine-containing(Methyl)Acrylate is original Material, has synthesized a series of fluoro-acrylate copolymer.Introduce full-fluorine group to change acrylate polymer by side chain Structure, so both maintained the original advantage of acrylate polymer, give again the distinctive hydrophobic, oleophobic of fluoropolymer, Weatherability and self-cleaning performance so as to which integrated performance index is greatly improved.
There is shitosan certain bactericidal action to have inhibitory action to microbiologic(al) corrosion, play certain anti-pollution function, and Itself is nontoxic, it may be said that be a kind of not only anti-corrosion but also antifouling green material.The structure of shitosan is much like with cellulose, Equally there is good film property, the hydroxyl and amino in structure makes molecule interchain there is stronger hydrogen bond, can bear certain There is polar group as hydroxyl and amino in mechanical strength and tensile strength, and molecule, especially amino, become positively charged The lone pair electrons or pi-electron of coordination are formed after lotus with the outer layer unoccupied orbital with ferrum, adsorption layer is increased with metal surface active force By force, adsorb membrane stability to improve.
Therefore the present invention is using methacrylic acid-beta-hydroxy ethyl ester grafting highly-chlorinated polyethylene, poly- using aqueous-phase suspending afterwards It is legal that methacrylic acid-beta-hydroxy ethyl ester, Hexafluorobutyl mathacrylate monomer are successfully grafted in chitosan molecule, it is prepared for Chitosan graft fluorinated acrylate/highly-chlorinated polyethylene terpolymer so that anticorrosive paint has higher pollution resistance, pole Good anti-corrosive properties, excellent coating and excellent adhesive force.
