Abstract
The invention discloses a preparation method of environment-friendly PU plastic for race tracks. The preparation method is characterized in that the PU plastic comprises the components of polyether polyol, diphenyl methane diisocyanate, 1,4-butanediol and an organic composite rare-earth catalyst; the preparation method comprises the steps of prepolymerization, removal of air bubbles in vacuum, pouring, curing and finished product forming. The PU plastic prepared by the preparation method has low toxicity and good mechanical property; a plastic race track prepared with the PU plastic is safe, environment-friendly and free from defects such as bubbles and depression.
Description
Technical field
The present invention relates to the plastic cement preparing technical field, particularly relate to the preparation method of a kind of runway with environment-friendly type PU plastic cement.
Background technology
The polyurethane plastic runway overwhelming majority of laying at present is mixed type, its basic recipe is the TDI(tolylene diisocyanate)-MOCA(3,3 ＇-bis-chloro-4,4 ＇-diaminodiphenyl-methane)-heavy metal catalyst system, cause be laid to plastic cement race track to have the problem of poisoning and laying high cost.TDI belongs to II level poisonous substance, it is suspicious human carcinogen's thing, international movement runway technology association (IST) just proposed the suggestion of " not accepting to use the motion runway containing the polyurethane system of TDI composition " as far back as 1994, MOCA belongs to arylamine ester class chemical, toxicity is larger, can cause bladder cancer, take organic mercury/lead or organic mercury/zinc composite catalyst as main heavy metal catalyst system harmful to human, contaminate environment.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the preparation method of a kind of runway with environment-friendly type PU plastic cement, can solve the large problem of conventional P U plastic cement race track toxicity.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the preparation method of environment-friendly type PU plastic cement for a kind of runway, and component comprises: polyether glycol, diphenylmethanediisocyanate, BDO, organic composite rare earth catalyst; Preparation method's step is: prepolymerization-vacuum outgas bubble-cast-solidify-finished product.
In a preferred embodiment of the present invention, described organic composite rare earth catalyst is isooctoate of rare earth metal and isocaprylic acid zinc, and proportioning is 2:1.
In a preferred embodiment of the present invention, described prepolymerization method is: in reaction vessel, add polyether glycol, stirring is warmed up to certain temperature, and vacuumize stirring dehydration l h, after having dewatered, be cooled to temperature required, add the diphenylmethanediisocyanate that becomes certain proportioning with polyether glycol, BDO, finally add the organic RE composite catalyst.
In a preferred embodiment of the present invention, the technique of described vacuum outgas bubble is: vacuum tightness 0.02～0.05MPa, time 2h.
In a preferred embodiment of the present invention, described curing process is: 140 ℃ of solidification values, set time 4h.
In a preferred embodiment of the present invention, the temperature that described stirring heats up is 110～120 ℃.
In a preferred embodiment of the present invention, described temperature required be 50～60 ℃.
