A kind of heat fusing high abrasion antipollution white traffic marking material and preparation method thereof
Technical field
The present invention relates to traffic technique field, particularly a kind of heat fusing high abrasion antipollution white traffic marking material and preparation method thereof.
Background technology
In recent years, along with traffic technique development with rapid changepl. never-ending changes and improvements, different kinds of roads graticule is all widely used in the field such as highway and airport of various grades, has played effect more and more easily in daily life and traffic trip.Roadmarking not only will pass through wind, Exposure to Sunlight on traffic route after application, drench with rain outside, also to invade stain through the greasy dirt on road surface, wheel roll wearing and tearing, very person also will often face northerly winter such as tearing of antiskid chain, the erosion of snow-melting agent etc.So the singularity of traffic marking applied environment, has determined the singularity of the material of preparing roadmarking itself.
At present, commercial hot-melt type road mark paint adopts the mixed low-grade road traffic marking materials that form such as the hot-melting type such as petroleum resin and modified rosin resin macromolecule adhesive and stone flour substantially, this material only can meet the use of low side traffic route, requires harsh environment just can not meet its needs for the roadmarking such as motorway, airport.Be mainly manifested in the following aspects: first, heat fusing road traffic marking material is due to not science of its material mixture ratio, cause contaminated phenomenon with regard to as easy as rolling off a log, during the broiling summer time, graticule material makes surfaces of tacky because envrionment temperature raises, thereby causes the dirt on automobile tyre to cover on graticule surface by rolling of wheel, makes graticule surface present grey black, affect the visual effect of graticule, greatly increased the hidden danger that traffic accident occurs; Secondly, graticule material is in the winter time time, and because sticking power is poor, in the time running into microthermal climate, coating surface becomes fragile, easily coming off of occurrence of large-area; Simultaneously, because the wear resistance of this graticule is poor, do not reach corresponding frictional coefficient, when ice and snow etc. is in the time that roadmarking surface coverage reaches certain thickness, this graticule surface can become Paint Gloss than road surface, more easily causes the generation of traffic accident.
Summary of the invention
In view of the problem that above-mentioned prior art exists, the invention provides a kind of heat fusing high abrasion antipollution white traffic marking material and preparation method thereof, for improving wear resistance and the contamination resistance of traffic marking, and strengthen the sticking power of traffic marking.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of heat fusing high abrasion antipollution white traffic marking material, comprises the component of following parts by weight:
15 ~ 18 parts of petroleum resin, 5 ~ 8 parts of modified rosin resins, 0.2 ~ 0.5 part of n-butyl phthalate, 2 ~ 4 parts of titanium dioxide, 8 ~ 10 parts of glass microballons, 0.05 ~ 0.2 part of stilbene biphenyl sodium disulfonate, 5 ~ 8 parts of ethylene vinyl acetates, 1 ~ 2 part of microcrystalline wax, 0.2 ~ 1 part of refining white mineral oil, 20 ~ 30 parts of quartz sands, 28 ~ 32 parts of silica powders.
A kind of heat fusing high abrasion antipollution white traffic marking material, its improvement is to comprise the component of following parts by weight: 16.5 parts of petroleum resin, 6 parts of modified rosin resins, 0.36 part of n-butyl phthalate, 3 parts of titanium dioxide, 9 parts of glass microballons, 0.16 part of stilbene biphenyl sodium disulfonate, 6.9 parts of ethylene vinyl acetates, 1.35 parts of microcrystalline waxes, 0.55 part of refining white mineral oil, 27 parts of quartz sands, 29.18 parts of silica powders.
A preparation method for heat fusing high abrasion antipollution white traffic marking material, comprises the following steps:
a. successively to adding n-butyl phthalate and refining white mineral oil with being uniformly mixed in the reactor of function, stir by weight, leave standstill de-bubble for subsequent use;
b.start the fine material mixer with highly pressurised liquid spray equipment, stirring velocity is controlled at 30rad/min, successively petroleum resin, modified rosin resin, titanium dioxide, glass microballon, stilbene biphenyl sodium disulfonate, ethylene vinyl acetate, microcrystalline wax, quartz sand, silica powder order are joined and in fine material mixer, complete material loading by screw feeding machine by weight, after material loading, stirring velocity is promoted to 50rad/min, continues to stir for 30 seconds;
c.keep under this rotating speed agitation condition, the n-butyl phthalate of having prepared in reactor, refining white mineral oil are added by pipeline delivery pump in the high-pressure spray device of fine material mixer, control spray flow, this material is added in fine material mixer in vaporific mode with 20rad/min speed, after material spray
Controlling stirrer rotating speed is 30rad/min, continues to stir for 60 seconds, can be made into a kind of heat fusing high abrasion antipollution white traffic marking material.
Owing to having adopted above technical scheme, the invention technological progress is as follows:
The present invention, through the strict proportioning to various materials, forms the free of contamination white traffic route graticule of high abrasion by hot melt techniques.This graticule has good weathering resistance, wear resistance, in use without color and luster change, graticule is clear, not easy to crack, there is good reflective, in long-term, reflecting effect can not decline, road pavement has good glutinous viscosity, incrust, can adapt to the normal deformation on road surface and not produce the advantages such as displacement.
Ethylene vinyl acetate in the present invention is in preparation process, according to the size of the molecular weight of ethene and vinyl acetate between to for plastic, at ethene and vinyl acetate between to for plastic polyreaction initial stage, by ethene and vinyl acetate between to for plastic, the temperature in polymerization process is controlled between 72 DEG C to 73.5 DEG C, and use peroxidation class initiator to carry out the pre-initiation at polymerization initial stage, simultaneously in ethene and vinyl acetate between to for plastic reaction process, in reactor, keep the high pressure conditions of 16kP, make the ethylene vinyl acetate forming there is splendid thermal adaptability and resistance to deterioration, ethylene vinyl acetate is applied in the present invention, the graticule that can make the present invention prepare has splendid antipollution effect, summer can the deliquescing because of high temperature, can not become fragile because of low temperature winter, can form good bonding sticking power with road surface, do not have the fracture of crackle.
Graticule material of the present invention is by making titanium dioxide and coordinating of whitening agent stilbene biphenyl two sodium sulfonates the color of white traffic marking extremely bright-coloured obviously, and opacifying power is stronger, and visual effect is splendid.The present invention, due to the interaction having between glass microballon and whitening agent stilbene biphenyl sodium disulfonate, strengthens reflecting effect greatly, ensures that driver strengthens the insight of traffic marking in the time driving.By the proportioning of different meshes silica powder, make the coating surface forming there is higher frictional coefficient, prevent from after-tacking, improve coating antiwear heat resisting, be difficult for causing tire to skid on roadmarking surface.The present invention is due to the rational proportion of refining white mineral oil, n-butyl phthalate, there is splendid contamination resistance, also can make the coating forming can keep chromatic colour in road surface, be difficult for the dirt on bonding tire and road surface, and change the fragility of coating, improved its ability of anti-deformation.The present invention is because the presentation materials that has the ethylene vinyl acetate of science and the reasonable disposition of microcrystalline wax can ensure that this material forms has splendid flexibility and uviolresistance, and be difficult for by the pollutions such as vehicle tyre and other road surface dirt, the significantly duration of service of lifting road marking lines.
