Description
Technical field
The present invention relates to technical field of transportation, particularly a kind of heat fusing high abrasion antipollution White traffic graticule material and preparation method thereof.
Background technology
In recent years, the development of making rapid progress along with traffic technique, different kinds of roads graticule is all widely used in the fields such as the highway of various grade and airport, serves and act on more and more easily in daily life and traffic trip.Roadmarking not only outside wind, Exposure to Sunlight, drenching with rain, also will will invade stain through the greasy dirt on road surface after application on traffic route, wheel roll wearing and tearing, notably also to often face tearing of antiskid chain, the erosion etc. of snow-melting agent northerly winter.So the singularity of traffic marking applied environment, determines the singularity of the material preparing roadmarking itself.
At present, the low-grade road traffic marking material that commercial hot-melt type road mark paint adopts the hot-melting type such as petroleum resin and modified rosin resin macromolecule adhesive and stone flour etc. mixed substantially, this material only can meet the use of low side traffic route, requires that 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 its material mixture ratio not science, contaminated phenomenon is caused with regard to as easy as rolling off a log, time during the broiling summer, graticule material makes surfaces of tacky because envrionment temperature raises, thus causes the dirt on automobile tyre to be covered by rolling of wheel on graticule surface, makes graticule surface presentation grey black, have impact on the visual effect of graticule, considerably increase the hidden danger that traffic accident occurs; Secondly, graticule material in the winter time time, because sticking power is poor, when running into microthermal climate, coating surface becomes fragile, coming off of easy 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. reaches certain thickness in roadmarking surface coverage, this graticule surface can become more smooth than road surface, more easily causes the generation of traffic accident.
Summary of the invention
In view of above-mentioned prior art Problems existing, the invention provides a kind of heat fusing high abrasion antipollution White traffic graticule material and preparation method thereof, for improving wear resistance and the contamination resistance of traffic marking, and strengthening 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:

Petroleum resin 15 ~ 18 parts, modified rosin resin 5 ~ 8 parts, n-butyl phthalate 0.2 ~ 0.5 part, titanium dioxide 2 ~ 4 parts, glass microballon 8 ~ 10 parts, stilbene biphenyl sodium disulfonate 0.05 ~ 0.2 part, ethylene vinyl acetate 5 ~ 8 parts, microcrystalline wax 1 ~ 2 part, refining white mineral oil 0.2 ~ 1 part, quartz sand 20 ~ 30 parts, silica powder 28 ~ 32 parts.
A kind of heat fusing high abrasion antipollution White traffic graticule material, its improvement is the component comprising following parts by weight: petroleum resin 16.5 parts, modified rosin resin 6 parts, n-butyl phthalate 0.36 part, titanium dioxide 3 parts, glass microballon 9 parts, stilbene biphenyl sodium disulfonate 0.16 part, ethylene vinyl acetate 6.9 parts, microcrystalline wax 1.35 parts, refining white mineral oil 0.55 part, quartz sand 27 parts, silica powder 29.18 parts.
A preparation method for heat fusing high abrasion antipollution White traffic graticule material, comprises the following steps:
a. add n-butyl phthalate and refining white mineral oil to in the reactor being uniformly mixed function successively by weight, stir, leave standstill de-bubble for subsequent use;
b.start the fine material mixer with highly pressurised liquid spray equipment, stirring velocity controls at 30rad/min, successively by screw feeding machine 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 in fine material mixer and complete material loading by weight, after material loading, stirring velocity is promoted to 50rad/min, continues stirring 30 second;
c.under keeping this rotating speed agitation condition, the n-butyl phthalate prepared in reactor, refining white mineral oil are added in the high-pressure spray device of fine material mixer by pipeline delivery pump, control spray flow, this material is added in fine material mixer in an atomized manner with 20rad/min speed, after material spray
Controlling stirrer rotating speed is 30rad/min, continues stirring 60 second, namely to can be made into a kind of heat fusing high abrasion antipollution White traffic graticule material.
Owing to have employed above technical scheme, the invention technological progress is as follows:
The present invention, through the strict proportioning to various material, forms the free of contamination White traffic roadmarking 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, the normal deformation on road surface can be adapted to and do 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 controls 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, the high pressure conditions of 16kP is kept in reactor, the ethylene vinyl acetate of formation is made to have splendid thermal adaptability and resistance to deterioration, by ethylene vinyl acetate application in the present invention, the graticule that the present invention can be made to prepare has splendid antipollution effect, summer can not the deliquescing because of high temperature, winter can not become fragile because of low temperature, good bonding sticking power can be formed with road surface, do not have the fracture of crackle.
Graticule material of the present invention makes the color of White traffic graticule extremely obviously bright-coloured by titanium dioxide with coordinating of whitening agent stilbene biphenyl two sodium sulfonate, and opacifying power is comparatively strong, and visual effect is splendid.The present invention, owing to there being the interaction between glass microballon and whitening agent stilbene biphenyl sodium disulfonate, makes reflecting effect greatly strengthen, and ensures that driver strengthens the insight of traffic marking when driving.By the proportioning of different meshes silica powder, make the coating surface of formation be provided with higher frictional coefficient, prevent from after-tacking, improve coating antiwear heat resisting, not easily cause tire at roadmarking slippery surface.The present invention is due to the rational proportion of refining white mineral oil, n-butyl phthalate, there is splendid contamination resistance, the coating of formation also can be enable to keep chromatic colour in road surface, not easily the dirt on bonding tire and road surface, and change the fragility of coating, improve its ability of anti-deformation.The present invention can ensure that the presentation materials that this material is formed has splendid flexibility and uviolresistance due to the reasonable disposition of the ethylene vinyl acetate and microcrystalline wax that have science, and not easily by pollutions such as vehicle tyre and other road surface dirts, can duration of service of significantly lifting road marking lines.
