Description
Technical field
The present invention relates to a kind of polyurethane bicomponent back cover material for plastic cement race track and preparation method thereof, belong to urethane applied technical field.
Background technology
The advantages such as plastic cement race track is suitable with its hardness, good springiness, and physicals is excellent, beautiful in colour, have excellent weather resistance, from being certainly born, progressively by everybody is approved and favor.At present, plastic cement race track can be divided into prefabrication type, full-plastic, mixed type, air-permeable, the compound and large type of EPDM type six.Yet this two broad aspect of comprehensive economy and practicality, air-permeable, mixed type, compound plastic cement race track are applied more general.Along with the raising of people's living standard, also harsher for the requirement of plastic cement race track, the demand of runway outward appearance is also no longer only limited to red, green two kinds of tones, the soft pastel shade runway attractive in appearance of color arises at the historic moment thereupon.At present, on market for laying the black particle (black rubber particle) of runway bottom, quality is whole general, easily separate out black, yellow substance, after the light plastic coats such as spraying blueness on this basis, there is the problems such as " flavescence ", " blackening " in short period plastic coat, causes the place appearance poor of laying, part place even need to pave again because spraying effect is too poor, causes serious financial loss.
At present take on black particle bottom after blade coating one deck slurry in part place, then spray the constructional method of light surface layer.There is on the one hand the drawback that blade coating is time-consuming, require great effort in this method, though can reach reasonable construction effect in several days time after construction simultaneously, but at high temperature, often within 1～2 week, occur the problems such as surface layer " blackening ", " dimmed ", place is still difficult to the construction effect having reached.And on market, there is the coating of high-quality opacifying power, being sprayed on the one hand black particle bottom oozes under easily, the covering effect that will reach on the other hand often needs to spray more than 2 times, construction trouble, even if spray the covering effect having reached after several times simultaneously, but be difficult to ooze on " black " that isolated black particle oozes out, " yellow " material, thereby the construction effect that also cannot reach.
