Abstract

The invention discloses an anticorrosive polyvinyl chloride resin coating and a preparation method. The coating is composed of an epoxy resin E-14, a polyvinyl chloride resin, monoethanolamine, xylene, siliceous lime powder, Texanol, methyltriethoxysilane, diaminodiphenylsulfone, a diffusant MF, polydimethylsiloxane, pyrocatechol, an antioxidant ODA and n-hexane. In the invention, the epoxy resin E-14 and the polyvinyl chloride resin are adopted as main materials of the anticorrosive coating, n-hexane is adopted as a solvent, a polymerization material is formed after the curing of the coat of the coating, the coating becomes a nontoxic and tasteless environmentally-friendly coat, the coat has a very good adhesion to the surface of steel, and the simultaneous addition of the siliceous lime powder, Texanol, methyltriethoxysilane and diaminodiphenylsulfone obviously increases the mechanical properties, the ageing resistance, the corrosion resistance and the like of the whole coating system.

Description

A kind of polyvinyl chloride (PVC) RESINS protective system and preparation method thereof
Technical field
The present invention relates to a kind of protective system, be specifically related to a kind of polyvinyl chloride (PVC) RESINS protective system and preparation method thereof.
Background technology
Metallic corrosion is that effective, the most the most frequently used method of protection against corrosion is to apply erosion shield in the metallic surface, and matrix and corrosive medium are completely cut off because the metallic surface is subjected to the chemistry of surrounding medium or electrochemical action and ruined phenomenon.The Corrosion Protection of coating is mainly reflected in coating to the solidity to corrosion of corrosive medium, and to the permeability resistance of medium.Therefore, improve the Corrosion Protection of coating, the one, select the solidity to corrosion resin, two are to use the protection against corrosion filler of excellent property; Epoxypaint has the sticking power height, and chemicals-resistant and solvent nature excellence, hardness height, advantage such as mill property is good, alkaline-resisting, salt fog resistance is good are widely used in the protective system field.
Summary of the invention
The object of the present invention is to provide a kind of polyvinyl chloride (PVC) RESINS protective system and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
The polyvinyl chloride (PVC) RESINS protective system, the weight part of its constitutive material is: Resins, epoxy E-14 45-50, polyvinyl chloride (PVC) RESINS 30-35, Monoethanolamine MEA BASF 1.0-1.2, dimethylbenzene 9-11, silica ashes 35-40, alcohol ester 12 2.0-3.5, Union carbide A-162 6.0-8.0, diamino diphenyl sulfone 13-18, dispersing agent MF 2.8-3.2, polydimethylsiloxane 3.5-4.5, pyrocatechol 1.7-2.3, anti-aging agent ODA 1.0-2.0, normal hexane 60-65.
The polyvinyl chloride (PVC) RESINS protective system, the weight part of its constitutive material is: Resins, epoxy E-14 48, polyvinyl chloride (PVC) RESINS 32, Monoethanolamine MEA BASF 1.1, dimethylbenzene 10, silica ashes 38, alcohol ester 12, Union carbide A-162 7.0, diamino diphenyl sulfone 15, dispersing agent MF 3.0, polydimethylsiloxane 4.0, pyrocatechol 2.0, anti-aging agent ODA 1.5, normal hexane 62.
The preparation method of polyvinyl chloride (PVC) RESINS protective system may further comprise the steps:
(1) modification of Resins, epoxy E-14 is handled: the weight part by constitutive material takes by weighing Resins, epoxy E-14, and then with Resins, epoxy E-14, methylimidazole, nanometer deposed brick slag powder and nano titanium oxide by weight ratio 80: 18-22: 1.5-1.7:10-15 mixes;
(2) compound A: the solvent normal hexane of step (1) and 2/5-2/3 is mixed, the weight part of pressing constitutive material then adds polyvinyl chloride (PVC) RESINS, Monoethanolamine MEA BASF, dimethylbenzene, silica ashes, alcohol ester 12, Union carbide A-162, dispersing agent MF, polydimethylsiloxane, pyrocatechol and anti-aging agent ODA, mixes and obtains compound;
(3) compound B: the weight part of pressing constitutive material mixes diamino diphenyl sulfone and remaining solvent normal hexane, and fully dissolving gets final product;
(4) the compound A of step (2) and the compound B of step (3) are got final product protective system by weight 1:0.9-1.1 mixing stirring 1.5-2.5h.
Beneficial effect of the present invention:
The present invention has adopted Resins, epoxy E-14 and polyvinyl chloride (PVC) RESINS as the major ingredient of protective system, normal hexane is as solvent, after applying coating solidifies, form polymeric material, become nonpoisonous and tasteless environment-friendly coating, steel surface there is fabulous sticking power, has added silica ashes, alcohol ester 12, Union carbide A-162 and diamino diphenyl sulfone simultaneously, the mechanical property, ageing-resistant performance, corrosion resistance nature etc. of whole coating system are obviously improved.
