Problems solved by technology

[0002] The current road is generally paved with asphalt, but the color of the asphalt is monotonous, and the driver is prone to visual fatigue when driving for a long time. A kind of colored resin pavement has appeared behind, such as the invention of application number CN201510436436. Slippery road surface and its construction method. After the colored resin is laid on the road surface, it can warn drivers and relieve visual fatigue on the one hand, and can beautify urban roads on the other hand.
[0003] However, the color of this colored resin is fixed and cannot be changed according to the temperature, and it cannot warn drivers and pedestrians when the temperature is high

Abstract

The invention relates to the technical field of road traffic, and particularly discloses a reversible thermochromic pavement coating and a preparation method thereof. The reversible thermochromic pavement coating comprises, by mass, 95-100 parts of a water-soluble acrylic resin emulsion, 110-120 parts of a silicone resin emulsion, 3-5 parts of an antifoaming agent, 120-135 parts of bentonite, 75-80 parts of a thermochromic powder and 220-250 parts of deionized water. The reversible thermochromic pavement coating can alert the temperature.

Description

technical field [0001] The invention relates to the technical field of road traffic, and specifically discloses a reversible thermochromic pavement coating and a preparation method thereof. Background technique [0002] The current road is generally paved with asphalt, but the color of the asphalt is monotonous, and the driver is prone to visual fatigue when driving for a long time. A kind of colored resin pavement has appeared behind, such as the invention of application number CN201510436436. Slippery pavement and its construction method. After the colored resin is laid on the pavement, it can warn drivers and alleviate visual fatigue on the one hand, and can beautify urban roads on the other hand. [0003] However, the color of this colored resin is fixed and cannot be changed according to the temperature, and it cannot warn drivers and pedestrians when the temperature is high. Contents of the invention [0004] The object of the present invention is to provide a rever...
