Abstract
The present invention discloses a method for preparing high performance water-proofing and anti-corrosion paint. The components of the water-proofing and anti-corrosion paint take waste polystyrene plastic foams as a basal material. The water-proofing and anti-corrosion paint also comprises rubber, colophony, ethyl acetate, toluene, solvent and toluene di-isocyanate. According to weight portion mixture ratio, the basal material is weighted by 100 weight portion, and other components by weight portion of the water-proofing and anti-corrosion paint are: 30 to 60 weight portions of rubber, 10 to 20 weight portions of colophony, 30 to 60 weight portions of ethyl acetate, 30 to 60 weight portions of toluene, 50 to 70 weight portions of solvent and 1 to 5 weight portions of toluene toluene di-isocyanate. The preparing method comprises the following steps: firstly, placing fragments of the waste polystyrene plastic foams used as the basal material in a reactor; secondly, adding the colophony, the ethyl acetate, the toluene, the solvent and the toluene toluene di-isocyanate according to the mixture ratio, heating and dissolving the form plastics to be foamless; and finally, adding the rubber, mixing the components to be pasty, pulling out filaments and filtering. The paint prepared by the method has the advantages of high dispersity and penetrability, good weather resistance, acid, base and high temperature resistance, low preservation requirement, stable performance, simple preparing process, low process condition and low integrated cost. In addition, the method uses the waste polystyrene plastic foams as the basal material, thereby making waste into valuable and reducing the white pollution.
Description
Technical field
The present invention relates to a kind of preparation method who mainly utilizes waste polystyrene foam plastic for the high performance water proof anti-corrosive paint of base-material.
Background technology
Leakage of buildings and waterproof are a great problems of building trade always.More existing coating, polyvinyl chloride (PVC) class elastic water proofing paint for example, add coal tar, bituminous waterproof paint, problem such as adopt the waterproof paint etc. of neoprene latex, 851 tar polychlorostyrene ammoniacums all to have engineering cost height, cost height, complex process, contaminate environment, to be detrimental to health.In addition, existing a large amount of waste polystyrene foam plastic serious environment pollution.The CN1107869A patent application discloses a kind of chromatic elastic water proofing paint, is that base-material adding alkaline conditioner, properties-correcting agent, compound dispersion agent, packing material, colorant, stablizer, antifreezing agent, polyalcohols and silicon defoamer mixing manufacturing form by vinyl acetate between to for plastic-ethylene copolymerization emulsions.The CN1068896C patent provides a kind of thermal insulation elastic waterproof coating for building surface and preparation method thereof, and this coating contains the elastic top polymers of irradiation resin, aluminium powder and tolylene diisocyanate, the former two's sum and the latter's ratio 1:1.Preparation technology goes in the solvent discarded polyester is bottled, adopts cobalt 60 irradiation, adds auxiliary agent and becomes the irradiation resin, mixes getting final product then with tolylene diisocyanate and aluminium powder.The CN1286282A patent application discloses a kind of water-proof paint of modified polystyrene and preparation method thereof.Contain dimethylbenzene, poly-third ethene, dibutylester and talcum powder, its manufacturing process comprises: a. is with the dimethylbenzene input; B. poly-third vinyl foam or the particle of above-mentioned part by weight are sneaked into, dissolved; C. poly-third vinyl foam or particle dissolving back add dibutylester and stir to be mixed it and dissolves; C. poly-third vinyl foam or particle dissolving back add dibutylester and stir to be mixed it and dissolves; D. evenly cast aside talcum powder and stirring.
Summary of the invention
The object of the invention is to provide that a kind of dispersity height, seepage force are strong, the preparation method of good weatherability, acid and alkali-resistance, high temperature resistant, shelf-stable, high performance water proof anti-corrosive paint that suitability is wide.
Technical scheme of the present invention is: 1) base-material waste polystyrene foamed plastics fragment is placed reactor;
2) component is base-material with the waste polystyrene foamed plastics, also comprise rubber, rosin, ethyl acetate, toluene, solvent and tolylene diisocyanate, by its weight part proportioning be: base-material is in 100 weight parts, the proportioning of other component is: rubber 30-60, rosin is 10-20, and ethyl acetate is 30-60, and toluene is 30-60, solvent is 50-70, and tolylene diisocyanate is 1-5.Add rosin, ethyl acetate, toluene, solvent, tolylene diisocyanate by above proportioning, heat, porous plastics is dissolved to still.3) add rubber mix to scattered paste shape, pull out filament, filter.
Beneficial effect of the present invention is: because preparation method of the present invention mainly utilizes waste polystyrene foam plastic to be base-material, preferred material modified and other auxiliary agent and waste rubber blend have been added, select rational technology for use, make this coating have high degree of dispersion and seepage force, good weatherability, acid and alkali-resistance and high temperature, storage requires low, stable performance.Its manufacturing process is simple, processing condition are low, comprehensive cost is low.In addition, the present invention is a base-material with the waste polystyrene foam plastic, turns waste into wealth, and reduces " white pollution ".
Embodiment
It is base-material that component is selected the 1Kg waste polystyrene foam plastic for use, base-material is broken into fritter places chuck to have the reactor of agitator, add rosin 120g, ethyl acetate 580g, toluene 350g, solvent 550g, tolylene diisocyanate 40g more successively, be warming up to 55 degrees centigrade, reaction 4h fully dissolves to porous plastics, add useless regenerated rubber liquid 300g blend again, to forming scattered paste shape, pull out filament, refilter.-92 pairs of products of establishing criteria JC/T674-1997, JC500 are tested, and be surface drying 2h its time of drying, tack-free, does solid work 10h, do not have adhesion; When temperature is 80 degrees centigrade, the time is when being 2h, the thermotolerance test result, product do not have trickling, do not have bubble, fricton-tight; Tension set reaches 243%; Test under 0.1MPa, 30min condition, sample does not have infiltration; Cohesive strength reaches 0.37MPa.
