Abstract
The invention discloses a glass flake anticorrosive coating, which consists of the following raw materials in percentage by weight: 16-30 percent of epoxy vinyl ester resin, 12-25 percent of polystyrene ester resin, 15-30 percent of glass flake, 1-5 percent of silane, 2-6 percent of dimethyl benzene, 0.2-2 percent of antifoaming agent, 0.1-6 percent of paraffin and the balance of talc powder filler. The invention has the advantages that: by selecting a scientific mixture ratio for the talc powder filler and each raw material, the mechanical strength of the coating is enhanced, the strength at a position under a large stress (such as the corner of equipment, the root of a flange, the joint between the bottom wall and the side wall of a storage tank and the like) is ensured, and construction is convenient; and the glass flake anticorrosive coating can be applied to occasions of anticorrosive linings such as wet process flue gas desulfurization absorption devices, petrifaction storage tanks and the like.
Description
Technical field
The present invention relates to a kind of protective system, especially relate to the glass flake anticorrosion paint of the Corrosion resistant linings use of the field devices such as a kind of chemical industry, ocean, oil, food, metallurgy, pipeline.
Background technology
Glass-flake coating belongs to a kind of effective heavy duty system, because glass flake is parallel to each other and overlapping arrangement in the inside of filming, not only coating be divided into many little spaces and greatly reduce string stress and the coefficient of expansion of coating, and can form the barrier that prevents Medium Diffusion, force the roundabout infiltration of medium, extend the time that medium osmosis is diffused into matrix, thereby increase anti-permeability performance and the physical strength of filming, reach the purpose that extends the anticorrosion time of matrix.U.S. Owens-Coming Fiberglass company is used for cold coating, glass reinforced plastic, clay etc. in nineteen fifty-seven to glass flake and is studied and it is used for equipment lining as anticorrosive.Doomsday in the sixties is originally introduced glass flake and coating from the U.S., since the seventies, has used on the oil field abroad and has obtained certain development, particularly uses more in Europe.China raises 300,000 tons of ethylene units of son at the eighties initial stage from what Japanese Toyo Kogyo, Ltd. introduced, and wherein the equipment such as flue gas desulfurization heat absorbing glass flake paint tower has also adopted this material.Some R﹠D institutions of China are also in the eighties begin one's study mid-term glass flake and glass-flake coating and obtained using quite widely.Because the intensity of existing glass-flake coating self is lower, at the larger position that meets with stresses, as to be coated in the coatings such as the diapire of equipment nook, flange root, hold-up vessel and sidewall junction are all flimsy weak links, often need to strengthen guaranteeing with glass reinforced plastic the work-ing life at these positions.
Summary of the invention
The object of the present invention is to provide a kind of self intensity high, have the glass flake anticorrosion paint of superior wear-resisting, high temperature resistant and corrosion resistance.
For achieving the above object, the present invention can take following technical proposals:
Glass flake anticorrosion paint of the present invention, it is that its weight percent proportioning is by raw material epoxy vinyl fat resin, polystyrene ester resin, glass flake, silane, dimethylbenzene, defoamer, paraffin and media assemblage: epoxy vinyl fat resin 16-30%; Polystyrene ester resin 12-25%; Glass flake 15-30%; Silane 1-5%; Dimethylbenzene 2-6%; Defoamer 0.2-2%; Paraffin 0.1-6%; Surplus is talcum powder.
The weight percent proportioning of described raw material is: epoxy vinyl fat resin 16%; Polystyrene ester resin 25%; Glass flake 30%; Silane 5%; Dimethylbenzene 6%; Defoamer 2%; Paraffin 6%; Talcum powder 10%.
The weight percent proportioning of described raw material can be: epoxy vinyl fat resin 30%; Polystyrene ester resin 12%; Glass flake 15%; Silane 1%; Dimethylbenzene 2%; Defoamer 0.2%; Paraffin 0.1%; Talcum powder 39.7%.
The weight percent proportioning of described raw material also can be: epoxy vinyl fat resin 20%; Polystyrene ester resin 18%; Glass flake 20%; Silane 3%; Dimethylbenzene 5%; Defoamer 1%; Paraffin 2%; Talcum powder 31%.
The weight percent proportioning of described raw material also can be: epoxy vinyl fat resin 25%; Polystyrene ester resin 15%; Glass flake 21%; Silane 2%; Dimethylbenzene 4%; Defoamer 0.5%; Paraffin 0.5%; Talcum powder 32%.
After above-mentioned raw materials was taken according to weight part, stirring in stirrer got final product.Storage method: 5-25 ℃ of drying at room temperature preserved.
During use, that the removing surface of pending equipment is clean, use hairbrush to smear or get final product with airless spraying.
The invention has the advantages that by the proportioning that adopts science between talcum powder and each raw material and select, improved the physical strength of coating self, guaranteed in the intensity of (junction etc. between as the diapire of equipment nook, flange root, hold-up vessel and sidewall) that meets with stresses when using than large part, easy construction can be applicable to the occasions such as protection against corrosion liner such as wet process of FGD absorption unit, petrochemical industry basin.
The physical and chemical index of coating of the present invention is as follows:
Coating thickness: 0.12-0.33mm; Ambient cure time: 3-5 hour; Shock-resistant: 60kg.cm; The room temperature acid resistance: 7 days unchanged; The room temperature alkali resistance: 7 days unchanged; The salt spray resistance of filming: 130 hours unchanged.
Compare with existing glass-flake coating, intensity can be improved 30～40MPa, make more than service life of equipment extends half a year.
