Abstract

The invention discloses a road-used multifunctional coating material with heat insulation and reduction and automobile exhaust treatment functions and a preparation method of the road-used multifunctional coating material. The road-used multifunctional coating material is prepared from the following ingredients by weight percent: 50-60 parts of a silicone acrylic emulsion, 15-25 parts of water, 5-9 parts of Fe-doped alumina supported nano-titanium dioxide, 5-9 parts of hollow glass beads, 5-9 parts of titanium dioxide, 11-14 parts of superfine diatomite, 5-9 parts of propylene glycol, 0.3-2.1 parts of an additive and 0.6-0.9 part of a dispersant. The preparation method is simple, and the road-used multifunctional coating material reasonably utilizes the favorable properties of pigments and fillers, not only can remarkably reduce the road surface temperature but also well degrade harmful ingredients in tail gas, and reduces environmental pollution caused by tail gas. Meanwhile, the road-used multifunctional coating material has relatively good weatherability, causes no secondary pollution during use and is an efficient and environment-friendly coating material.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to a road-use multifunctional coating material capable of both heat insulation and cooling and automobile exhaust treatment and a preparation method thereof. Background technique [0002] As a black pavement material, asphalt mixture has a high absorption rate of sunlight, which leads to a high temperature on the asphalt pavement. The use performance and service life of the road, and the heat of the road surface is continuously released to the outside when the temperature is low at night, which keeps the outside temperature high for a long time, which is also one of the reasons for the urban heat island effect. [0003] Today, with the rapid economic development, the per capita car ownership continues to increase. my country has become the world's largest motor vehicle production and sales country for three consecutive years. Vehicles emit a large amou...
