Problems solved by technology

[0005] The purpose of the present invention is to solve the problems in the prior art. In the prior art, the rubber material takes a long time to cure in rainy days, and it takes a long time to cure, and under the irradiation condition of strong sunlight, The rubber material is easily oxidized and makes the rubber material yellow; the molecular structure of MDI contains two benzene ring structures, of which the NCO group is directly connected to the benzene ring. Ultraviolet rays between -400nm can easily cause the photodegradation of the adhesive to produce chromophoric groups, which will cause the adhesive to turn yellow, and the ether bond of the adhesive has poor thermal oxygen stability. It is easy to oxidize to produce carboxyl and aldehyde groups, and accelerate the yellowing problem, and propose a color breathable adhesive rubber pavement material and its preparation method

Abstract

The invention discloses a preparation method of a colorful breathable adhesive rubber pavement material. The preparation method comprises the following steps: S1, granulating modified rubber through a granulator to obtain rubber particles; and S2, adding the rubber particles, an adhesive and a coloring agent into a tank, conducting stirring for 20 minutes at a temperature of 130 DEG C, and carrying out compacting and curing in a mold to obtain the colorful breathable adhesive rubber pavement material. A preparation method for a modified rubber material comprises the following steps: adding diphenylmethane diisocyanate and a pure nonylphenol polyoxyethylene ether acrylate product into a reaction container, adding 200 ml of distilled water for dissolving, introducing nitrogen under a stirring condition, adding an initiator, conducting reacting for 30 minutes under a temperature condition to obtain a polymerization product, washing a polymerization product with methanol, and drying the polymerization product so as to obtain the modified rubber material is obtained. The modified rubber material and the modified adhesive enable the rubber pavement material to have good discoloration resistance.
