Description
Technical field
The invention belongs to a kind of waterproof paint, particularly a kind of building field waterproof paint.
Background technology
Mainly be divided into waterproof paint and protective system at architectural employed coating, have waterproof, seepage control and rot-resistant function respectively.In actual applications, often need dope layer to have waterproof and rot-resistant function simultaneously, for example the influence of acid rain is increasing, and the external coating of architectural needs is waterproof and acidproof simultaneously.Utilize prior art can only coat waterproof paint and protective system formation waterproof layer and preservative coat respectively.Problem is to be exposed to outermost coating, no matter is waterproof layer or preservative coat, all can be damaged under the effect of acid rain, and then built-in anticorrosion or waterproof layer also can be destroyed, and coating is reduced the protective capability of architecture noumenon.
What in addition, existing waterproof paint had also has bigger harm, for example solvent-type waterproofing paint and polyurethane water-proof paint etc. to human body and environment.Existing waterproof paint and protective system much adopt oil to be prepared as raw material, obtain under the situation at the petroleum resources growing tension, cause the cost of waterproof paint and protective system constantly soaring inevitably.
Summary of the invention
The invention provides a kind of waterproof paint, have excellent waterproof barrier properties and antiseptic property, the coating of coating formation simultaneously has good mechanical performance and weather resistance.
Technical scheme of the present invention is as follows:
Waterproof paint comprises the polymkeric substance of the sulphur with net high-polymer structure.
The polymkeric substance of described sulphur accounts for more than 50% of coating gross weight.
Also comprise the solid powder/particle of evenly sneaking in the described coating, the polymkeric substance of solid powder/particle and described sulphur constitutes composition, and the weight ratio of the polymkeric substance of described solid powder/particle and sulphur is 3%-50%, and the fineness of solid powder/particle is 50 orders-300 orders.
The polymkeric substance of described sulphur is made in the following way: sulphur is mixed with properties-correcting agent carry out modification, sulphur is polymerization reaction take place in the process of modification, generate the polymkeric substance of sulphur, concrete grammar is to mix with properties-correcting agent after with the sulphur heat fused, and continues the polymkeric substance that heating generates sulphur; Described properties-correcting agent is aromatic hydrocarbons and/or diene (genus) hydrocarbon polymer and/or olefines hydrocarbon polymer, and the weight of described properties-correcting agent is 2%～40% of sulphur weight.
Described sulphur is crude sulfur, the sulphur of petroleum refinement or selexol process.
The temperature of described heat fused is 110～200 ℃.
Described solid powder/particle is the mixture of a kind of in the following material or some kinds: solid waste powder, the solid radiation waste powder that discharge in the lime-ash after the flyash behind the coal combustion, slag, the waste incineration, building waste lime-ash, chemical plant.
Technique effect of the present invention:
The main component of waterproof paint of the present invention is the polymkeric substance of sulphur.Sulphur itself has water-fast characteristic, but sulphur itself not the characteristics of easy-formation make it can't satisfy requirement as waterproof paint, in addition, the intensity of sulphur itself and corrosion resistance nature are not high, make sulphur be not suitable as waterproof, protective system yet.The present invention adopts the polymkeric substance of sulphur of net high-polymer structure as the main body of waterproof paint, and sulphur has generated the polymkeric substance of this sulphur through the modification polymerization reaction take place.The polymkeric substance of the sulphur that obtains after the modification has prolonged set time, and stability is strong, has favorable waterproof property, can effectively resist the corrosion of the anti-hydrogen sulfide of burn into of microorganisms such as the anti-sulfate-reducing bacteria of hydrochlorate burn into simultaneously.Therefore, waterproof paint of the present invention not only has the usefulness of waterproof, has the rot-resistant performance simultaneously, has solved the problems of the prior art.
Add solid powder/particle in the polymkeric substance of sulphur after, its density and intensity are greatly improved, and the ability that the waterproof that feasible use waterproof paint of the present invention forms, preservative coat opposing damage is strong, have prolonged the work-ing life of waterproof layer.The cause that many preservative coat inhibitor effectivenesses reduce fast is that breaking of preservative coat itself causes internal structure to be exposed, and the waterproof, the preservative coat opposing damage ability that therefore adopt waterproof paint of the present invention to form have significance for preservative effect by force.In addition, add solid powder/particle and make the cost of waterproof paint reduce, particularly adopt the environmentally harmful waste powder of some possibilities, play the effect of utilization of waste material on the one hand, can solve the problem of environmental pollution of waste on the other hand.The polymkeric substance of sulphur mixes the back pH value still for neutral with solid powder/particle, therefore waterproof paint of the present invention can not cause the pollution to environment.
In order to prove that the toxic substance that waterproof paint of the present invention is sneaked into is difficult to separate out, carried out toxic test in Country Environmental Analysis Test Center, carbon black powder in the battery about 20% is incorporated into the test block of making 10 * 10 * 5cm in the polymkeric substance of the sulphur after the modification, after pulverizing it, Country Environmental Analysis Test Center puts into after pure water soaks 10 days, use the cold atom absorption spectrophotometry, diphenyl carbazide spectrophotometry, ion selective electrode method and Yi Yansuan-pyrazoline light-intensity method is tested, detect the leachable in the pure water, its test result shows does not have the material stripping in the pure water, water quality is not polluted.
For the superiority that proves the acidproof salt tolerant of the present invention aspect has been carried out following experiment: according to national building material industry standard JC/T984-2005, do 6 of the real pieces of 10 * 10 * 10cm, wherein do compressive strength test for 3 after soaking 90 days in the hydrochloric acid of PH1, its data are 65.1MPa; Other 3 are soaked in 3% NaCI solution after 90 days and do compressive strength test, and its data are 65.4MPa (the blank real blocks of data that soaks through excessive erosion is not 61.2MPa), illustrate that its acidproof salt tolerant effect is fine.
Also according to national building material industry standard JC/T984-2005 the waterproof, the preservative coat that utilize the present invention to make have been done impermeability test, pressed 6.3cm, 6.4cm tests after the 6.5cm moulding, proves that its impervious pressure reaches 2.5MPa, has good impervious effect.
According to national building material industry standard JC/T984-2005 the waterproof of utilizing the present invention to make, the shrinking percentage of preservative coat are tested, shrinking percentage is 0.05%.
Waterproof, the preservative coat that utilizes the present invention to make carried out wear test according to national building material industry standard JC/T958-2005, when friction 200 times, only lost 0.19g.
According to national building material industry standard JC/T894-2001 waterproof, the preservative coat that utilizes the present invention to make carried out weathering test, do 3 10 * 10 * 40CM test blocks, testing its ultimate compression strength after 250 hours in the uviolizing of 45 degree is 46.7MPa (blank real piece is 31.3MPa).
According to the GBJ82-85 national standard waterproof, the preservative coat that utilizes the present invention to make the test of freeze-thaw-Rapid Cycle, its mass loss 0%, relative resilient modulus 85.2% have been carried out.
