Abstract
The present invention relates to a kind of house building roofing waterproof paint that is used for---the manufacture method of modified water-proof coating of polystyrene.It is raw material that the present invention adopts waste polystyrene foam, rosin, coal tar, dimethylbenzene etc., makes polystyrene modified resin through miscible copolymerization at a certain temperature, and then adds an amount of cement and stir and make modified water-proof coating of polystyrene.This manufacturing approach craft flow process is simple, and equipment used is few, and cost is low.The waterproof paint cohesiveness that adopts present method to make is strong, good waterproof performance, and heat-resisting, cold-resistant, acid and alkali-resistance, ageing-resistant, easy construction is not subject to seasonal restrictions, and can replace pitch, is the ideal material of roof waterproof.
Description
The present invention relates to a kind of waterproof paint, especially for the manufacture method of house building roofing waterproof paint-polystyrene waterproof paint.The waterproof paint that makes with this method is applicable to roofing, ground, vault, building jointing, squeegees, the waterproof at expansion joint, protection against the tide, leak stopping, anticorrosion etc.
As everyone knows, do roof waterproof usually, be to use petroleum pitch and linkrusta.During construction, endure the pitch contaminate environment of smoldering, operate not only dirty but also tiredly, and inflammable dangerous, should not construct in winter.Emulsificated asphalt water-proof painting material is because of the breakdown of emulsion of enduring cold, and deterioration failure is so can not use when construction below 0 ℃.Some engineering can not do waterproof homework because of winter construction at present, and has to stop work, and existing waterproof paint new variety polyvinyl chloride waterproofing unction need heat during use, and easily catches fire, valuable product.
The purpose of this invention is to provide a kind of manufacture method that can replace the bituminous modified water-proof coating of polystyrene.This method is not only simple to operate, grasp easily, but also because of adopting waste polystyrene foam to make raw material, utilization of waste material greatly reduces product cost, reaches the purpose that improves the economic and social benefits.
The object of the present invention is achieved like this: adopt through the waste polystyrene foam of purifying treatment and rosin, coal tar, dimethylbenzene etc. and make raw material, according to a certain ratio raw material is dropped in the polymeric kettle, under the condition of 35～45 ℃ of temperature, stirred 2～2.5 hours, obtain polystyrene modified resin through abundant miscible copolymerization, (model is 325 to add an amount of cement again
#Or 425
#) promptly make modified water-proof coating of polystyrene through stirring.Adding cement helps to fill and lead up the slit and the rough and uneven in surface part of roofing of buildings, can reduce the contraction of glue-line simultaneously, avoids the internal stress that produces because of shrinking.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the process flow sheet of modified water-proof coating of polystyrene manufacture method of the present invention.
According to process chart shown in Figure 1, at first with the waste polystyrene foam process purified treatment that reclaims, remove foul, be by weight percentage again: polystyrene foam: rosin: coal tar: dimethylbenzene=(7～11): (15～30): (28～40): (28～40), its best proportioning is: polystyrene foam: rosin: coal tar: dimethylbenzene=8: 20: 36: 36. Raw material is dropped in the polymeric kettle, and polymeric kettle can be made by materials such as carbon steel or enamel. Stirred 2～2.5 hours under 35～45 ℃ of conditions, obtain the Polystyrene resin after fully fused copolymerization, pour in the agitator tank, (model is 325 to add cement again＃Or 425＃), its percentage by weight is: Polystyrene portions of resin cement=(60～50): (40～50), its best proportioning is: Polystyrene portions of resin cement=55: 45 namely gets modified water-proof coating of polystyrene after stirring.
The manufacturing approach craft flow process of modified water-proof coating of polystyrene of the present invention is simple, and use equipment is few, easily operation, not only cost is low for the water-repellent paint that employing the method is made, and is cheap, and construction is not subject to seasonal restrictions, pollution-free, safety improve work efficiency, and caking property is strong, good waterproof performance, acidproof, alkaline-resisting, ageing-resistant, coating can reach the hot summer and not trickle not embrittlement in severe winter. The product that adopts manufacture method provided by the invention to produce, its technical indicator can reach:
1, heat resistance: 80 ℃
2, cold-resistant degree :-35 ℃
3, cohesive strength: 〉=2 kilograms per centimeter
2
4, acid resistance: in 10% sulfuric acid, hydrochloric acid soln, soak four days no changes.
5, alkali resistance: in 10% sodium hydroxide solution, soak four days no changes.
6, drying property: surface drying 2 hours
Did solid work 100 hours
7, watertightness: film on 5 * 5 centimetres of kraft paper with 20 centimetres of diameters, it is waterproof that high 20 centimeter water columns leave standstill a week.
Most preferred embodiment:
Take by weighing 36 kilograms of dimethylbenzene and drop in the polymeric kettle, take by weighing 8 kilograms through waste polystyrene foam and 20 kilograms of rosin after the purifying treatment, 36 kilograms of coal tar drop in the polymeric kettle simultaneously, and polymeric kettle can be made by carbon steel or enamel material.Under 35～45 ℃ of conditions of temperature, stirred 2～2.5 hours, after fully fused copolymerization, pour in the stirred pot, (model is 325 to add 82 kilograms of cement again
#Or 425
#) seal in the container of after stirring, packing into.Can make 182 kilograms of modified water-proof coating of polystyrene.
Claims (2)
1, a kind of house building roofing waterproof paint that is used for, the manufacture method of modified water-proof coating of polystyrene particularly, it is characterized in that adopting waste polystyrene foam, rosin, coal tar, dimethylbenzene is raw material, be by weight percentage: waste polystyrene foam: rosin: coal tar: dimethylbenzene=(7～11): (15～30): (28～40): (28～40), in the input polymeric kettle, be under 35～45 ℃ the condition in temperature, stirred 2～2.5 hours, make polystyrene modified resin through miscible copolymerization, add cement then, its weight percent is: polystyrene modified resin: cement=(60～50): (40～50), stirring makes modified water-proof coating of polystyrene.
2, waterproof paint according to claim 1, it is characterized in that raw materials used best proportioning is (weight percent): waste polystyrene foam: rosin: coal tar: dimethylbenzene=8: 20: 36: 36, the polystyrene modified resin of producing: cement=55: 45.
