Embodiment 1

[0014] Embodiment one: Epoxy polyurethane-olefin polymer interpenetrating network anticorrosion coating, described coating comprises

[0015] Olefin polymer, its preparation raw material is (weight part): styrene 50, acrylonitrile 50, benzoyl peroxide 1.5, accelerator D 0.3; Stir the styrene and acrylonitrile of described component at room temperature , add benzoyl peroxide and accelerator D in sequence, stir evenly, and polymerize to obtain vinyl polymer;

[0016] The first epoxy polyurethane, its preparation raw material is toluene diisocyanate, castor oil-glycerin-phthalic anhydride reactant, E-20 epoxy resin-polyether 210 mixture; Toluene diisocyanate and castor oil-glycerin-phthalic anhydride reactant According to the NCO / OH equivalent ratio of 3:1, the polyurethane prepolymer is obtained, and the prepolymer is mixed with the E-20 epoxy resin-polyether 210 mixture according to the NCO / OH equivalent ratio of 1.1:1.0 to obtain the first Epoxy polyurethane;

[0017] The se...

Embodiment 2

[0021] Embodiment 2: The components and methods are basically the same as in Embodiment 1, except that the castor oil-glycerin-phthalic anhydride reactant is replaced by castor oil or castor oil alcoholylate, which has the same effect.

Abstract

The present invention discloses a kind of epoxy polyurethane-alkene polymer interpenetrating network anti-corrosion paint and its preparation process. The paint consists of alkene polymer, epoxy polyurethane 120 and epoxy polyurethane 144 at the weight ratio of 1 to 1 to 1 as well as pigment and stuffing in 15-25 wt% of the paint. The paint has interpenetrating network to raise the compactness of the coating, performance superior to single epoxy polyurethane and alkene polymer. It may be used in anticorrosion of various apparatus and facilities, and possesses excellent shock and wear resisting performance, high hydrolysis tolerance, high cavitation resistance, acid, alkali, salt and solvent resistance, high strength and high elasticity.

Description

technical field [0001] The invention relates to an interpenetrating network anticorrosion coating, and also relates to a preparation method of the coating. Background technique [0002] Interpenetrating Polymer Network (IPN) is a novel heterogeneous polymer system with special properties formed by the tight permanent entanglement (or interpenetration) of two or more polymer networks. At least one polymer network is synthesized or crosslinked in the presence of another polymer network. Interpenetrating network polymer is a new type of multi-phase polymer material that realizes the physical blending of polymers by chemical methods. The approach has developed very rapidly and has now formed an independent branch of polymer blending and compounding, which occupies an important position in the theory and practice of polymer modification. [0003] IPN has the characteristics of forced mutual tolerance, interface interpenetration, and synergy. The so-called forced mutual compati...
