Summary of the invention
In order to solve above-mentioned problems of the prior art, the invention provides a kind of prescription and manufacture method of rostone, this kind rostone is that the organic solvent-free system is produced rostone, the problem that its later stage discharges obnoxious flavour can be solved, problems such as poor mechanical property, flame retardant resistance are not high can also be solved simultaneously.
The objective of the invention is to be achieved by following technical solution.The invention provides a kind of rostone, this rostone is prepared from by aqueous high molecular material and inorganic materials, wherein said aqueous high molecular material is acrylic ester emulsion, organosilicon-modified acrylate emulsion (calling organosilicon crylic acid latex in the following text), cinnamic acrylic ester emulsion (calling benzene emulsion in the following text), polyurethane-modified acrylic acid ester emulsion, tertiary ethylene carbonate-acrylic ester emulsion, the vinyl acetate-acrylate emulsion, hydroxyl acrylic emulsion, aqueous polyurethane dispersion, the organic silicon modified polyurethane dispersion, water-compatible amino resin, aqueous epoxy resins, one or more in the epoxy-modified acrylic acid emulsion etc.; Wherein, the viscosity of each emulsion is 50-2500mPas, and solids content (wt%) is 30-70%.
Wherein, the quality of described aqueous high molecular material accounts for the 2%-20% of prescription total mass.
Organosilicon crylic acid latex is that organosilane monomer and the acrylic monomer that will contain unsaturated link(age) coat the emulsion that polymerization technique is polymerized by nucleocapsid.It combines organosilicon fire-resistant, weathering resistance, chemical-resistant, low high tint retention, snappiness, the tack that is difficult for contaminative and acrylic resin of hydrophobic, surface energy.It is a kind of high weather-proof, high water-fast, resistant to pollution emulsion.Finished market product is arranged, optimize suitable organosilicon crylic acid latex needs of the present invention through test and satisfy following parameter: viscosity (25 ℃, 3 rotor 60r/min) 50-800mPas; Solids content (wt%) is 40-60%; 50-600mPas more preferably, solid content is 45-50%.
Benzene emulsion is to be got through emulsion copolymerization by vinylbenzene and acrylate monomer.Benzene emulsion is the more system of research in the letex polymerization, also is that the world today has one of ten big non-crosslinked type emulsions of essential industry using value.Benzene emulsion sticking power is good, and glued membrane is transparent, water-fast, oil resistant, heat-resisting, ageing-resistant performance is good.Milky white liquid, the band blue light.Finished market product is arranged, optimize through test and be fit to benzene emulsion needs of the present invention and satisfy following parameter: solids content (wt%) is 40~60%, and viscosity 80~2000mPas, level of residual monomers be less than 1.0%, pH value 8~9; Viscosity 80-1000mPas more preferably, solid content is 50-55%.
The content of urethane is 25%-65% in the polyurethane-modified acrylic acid emulsion.
That the rostone that acrylate resin (PA) makes as base-material has is weather-proof, anti-pollution, acidproof, alkaline-resisting, performance such as the transparency is good, and production cost is lower, therefore is widely used as the base-material of rostone water-based.Yet the polyacrylate(s) rostone also exists shortcomings such as low temperature easily becomes fragile, the high temperature change is glutinous, has influenced its decorative effect and use value.For this reason, adopt the research of other resin modified polyacrylic ester resinoid to be subjected to people's extensive concern.In urethane (PU) molecule because containing a large amount of ammonia ester bonds and urea key etc., easily form hydrogen bond between macromole, produce extensive physical crosslinking, make latex film have excellent solvent resistance, wear resistance, damage resistant, snappiness and elasticity etc., but its production cost is higher, and the urethane that urethane and polyacrylic ester are combined and obtain.Polyacrylic ester (PUA) composite emulsion not only greatly reduce production cost, and latex film is with both advantages.
Preferred water-based macromolecular material is made up of the organosilicon crylic acid latex of 44-64%, the benzene emulsion of 20-40%, the polyurethane-modified acrylic acid emulsion of 8-25%.

Compare with traditional technology, technical scheme of the present invention has following excellent characteristics:
1) employed aqueous high molecular material all has the excellent water tolerance energy, has ensured that the water-based rostone of made has the excellent water tolerance energy.
2) owing to adopted the aqueous high molecular material to replace traditional vibrin, no longer contain the composition of solvent in the system, avoided rostone in use to discharge obnoxious flavour.The tradition rostone is its VOC(volatile organic compounds after tested) can reach 300-400ppm, and the test of water-based rostone can't check VOC.
3) the aqueous high molecular material contracts rate of Cai Yonging is very little, and the deformation in the course of processing of the rostone of making is very little, is easy to the processing typing, also is of value to and makes seamless spliced panel.
4) the aqueous high molecular material of Cai Yonging itself has higher heat-drawn wire, and because the cohesive force of material itself is very high, less consumption can reach requirement, can improve the ratio of other inorganic materials, thereby make the water-based rostone have higher resistant, thermotolerance, flame retardant resistance and higher mechanical property.
5) because used aqueous high molecular material has higher weathering resistance, can ensure that the water-based rostone has higher weathering resistance in using out of doors.
