Chinese Patent Publication No. 1354204 A discloses a kind of colored asphalt and its preparation method. It adopts the debasement asphalt method. Not only the manufacturing process is complicated, but also the prepared colored asphalt cannot completely get rid of its inherent dark brown, and the color effect is not good. At the same time, the variety of colors is also limited
Chinese Patent Publication No. 1097014 A discloses a color pavement cement and its preparation method. This invention improves the temperature sensitivity and wear resistance of the color pavement cement, but uses petroleum resin, SBS and lubricating oil to refine and extract oil as raw materials. First of all, the refined lubricating oil is complicated to make and the cost is high. Secondly, the compatibility between the three components of petroleum resin, SBS and lubricating refined extracted oil is poor, so that SBS is difficult to disperse in the system. Therefore, the preparation method is complicated and the production cycle is long. The three components cannot be uniformly dispersed in the system. For details, see Example 2 when the amount of SBS is as high as 20%, and the softening point is only 55°C. Obviously, SBS does not fully play its role.

Abstract

A light-color cementing material for building road, especially the color pavement, is prepared from polymer, filling oil and resin through proportioning the polymer and filling oil, pugging at 80-200 deg.C for 10-30 min, mixing with others and stirring.

Description

technical field [0001] The invention relates to a road-building material, mainly referring to a light-colored cementing material for making colored pavement roads, and at the same time relates to a preparation method thereof. Background technique [0002] Colored pavement has a good effect on organizing and controlling traffic. Paving roads of different colors can give drivers signals more naturally than vertical traffic signs to some extent; colored pavement can better coordinate the buildings around the road Art embodies the characteristics and style of a country or a city. Colored building materials are also widely used in the living environment and sports facilities to achieve the effect of beautification and decoration. Therefore, in today's developed world tourism industry, the colorization of commercial blocks and tourist spots has become a hot spot. [0003] Since the advent of colored asphalt for forty years, there have been many preparati...
