Problems solved by technology

This technical scheme uses more raw materials, high cost and complicated preparation process
The second type, such as Japan, announced a colored paving adhesive in Zhao 62-189203, commonly referred to as colored asphalt, which does not contain asphalt components, but is entirely composed of modifiers and organic polymers. This technical solution has the advantages of easy coloring and various colors, but it is expensive, the source of raw materials is limited, the process is complicated, and it is difficult to produce in large quantities.

Abstract

The invention relates to a light color cementing material which comprises the components mixed according to the parts by weight: 500-700 parts of base material oil, 190-450 parts of modifying agent, 45-100 parts of macromolecule copolymer, 1-10 parts of auxiliary agent and 2-6 parts of covering agent. The light color cementing material has the advantages of low cost, easy construction, good adhesion with aggregate, high temperature stability, good low temperature crack resistance and strong water damage resisting capability. After being mixed with pigments with different colors, the light color cementing material can be made into pavement materials with different colors, so as to be applicable to squares, parks, amusement parks and sidewalk road and have the function of beautifying the environment and guiding traffic; furthermore, the performance of the light color cementing material can reach the requirements of city expressway, highway and first class highway.

Description

technical field [0001] The invention relates to a cementing material for pavement of colored pavements, in particular to a light-colored cementing material and a preparation method thereof. Background technique [0002] The colored pavement is rich in color, breaking the traditional monotonous black and white pavement color. The colored pavement has two functions: 1. Warning traffic, improving the recognition effect of drivers 2. Beautifying the urban environment and showing the humanity of the city. The core raw material for paving colored pavements is colored cement, which can be obtained in two ways: the first is to use an appropriate solvent to remove the black asphaltene in petroleum asphalt, leaving other components with lighter color , and with modified materials; the second is to use modern petrochemical products to deploy light-colored cementing materials with comparable properties to asphalt. The first Chinese patent with the publication number CN1354204A disclose...
