The component A is base polyurethane prepolymer for use as, and its preparation method is, by polyester（Ether）Polyhydric alcohol 110 ~ 120 DEG C, 0.09 ~ 1.5 ~ 2.0h is dehydrated under the conditions of 0.1mpa, MDI is subsequently adding（Methyl diphenylene diisocyanate）, addition is polyester（Ether）Many The 20 ~ 30% of first alcohol amount, react 2.5 ~ 3h, synthesis of polyurethane performed polymer；
The B component is chain extender, and its preparation method is, by 70% chain extender MOCA（Bis- chloro- 4,4- diaminourea hexichol of 3,3- Methane）With 30% fire retardant TCPP（Tricresyl phosphate（2- chloropropyls）Ester, You Mingsan（Chloro isopropyl）Phosphate ester）, in temperature 75 ~ 85 Melt under the conditions of DEG C, generate chain extender component.
A kind of to conveying belt scene fast repairing method, comprise the steps：
（1）, will conveying rubber surface polishing clean up；
（2）, by the A of above-mentioned solvent-free environment-protection conveyer belt Rapid-Repair glue, B component in proportion 1:1 ~ 2 mix homogeneously, will be mixed The polyurethane compositions for getting togather are poured on belt to be repaired, are scratched smooth；
（3）, after 50 ~ 60min can be fully cured under room temperature, belt conveyor is repaired and is finished.
The product that produced of the present invention, belongs to usual articles, in production, goods road transport, product use, Due to eliminating the composition of solvent, safety is greatly improved, and is also beneficial to environmental protection.
Polyurethane elastomer repair layer physical property is as follows：
The present invention is reasonable in design, there is provided a kind of Novel conveyer belt repair sheets for not containing any solvent, it is to avoid in because of product Contained solvent and the various unsafe factors that bring, with good market using value.
