Problems solved by technology

The wear layer has the effect of degrading automobile exhaust to purify the air, and solves the defects of easy peeling off of the photocatalyst from the road surface, rapid decline in degradation efficiency, and insufficient contact area for photocatalytic degradation reactions, and uses colored special aggregates with high polishing value In order to increase the friction of the road surface, the road surface can maintain excellent waterproof, fog-proof and anti-skid road performance. It also has the effect of visually serving as a traffic warning and beautifying the environment, and has a good combination with the road surface and is easy to construct.

Abstract

The invention relates to a color anti-skid ultrathin wearing layer capable of degrading automobile exhaust and a preparation method thereof. The wearing layer consists of the raw materials as follows: epoxy resin, modified epoxy resin, a composite photocatalyst, amine-terminated polyether, a curing agent, a curing accelerator and aggregates. The wearing layer also can be prepared from the raw materials as follows: double-component polyurethane, a composite photocatalyst, a curing agent, a curing accelerator and aggregates. Before the wearing layer is laid, the original road surface needs to be treated, then paying-off and edge protection are performed, binders are mixed, color anti-wear aggregates capable of degrading exhaust gas are scattered uniformly, non-bonded aggregates are recovered, and finally maintenance of the wearing layer, traffic control and opening are performed. The wearing layer has performances of degrading the automobile exhaust and purifying air, can increase the road friction so as to enable the road surface to maintain excellent water mist-proof and anti-skid pavement performance, achieves effects of traffic warning and environment beautifying visually, and has excellent environmental benefit and social benefit.

Description

technical field [0001] The invention relates to a road pavement structure and material, in particular to a colored non-slip ultra-thin wear layer capable of degrading automobile exhaust and a preparation method thereof. Background technique [0002] With the continuous and rapid development of China's economy, the continuous improvement of the income level of the people, the increase of car ownership and the development of road traffic, the problem of traffic congestion is becoming more and more serious, and at the same time it has caused great pollution to the atmosphere and the ecological environment. The current status of environmental pollution has received worldwide attention. In order to protect the living environment, countries all over the world have imposed strict restrictions on the emissions of greenhouse gases, harmful gases, and solid dust. [0003] In order to cope with a series of negative impacts brought about by the increase in road traffic and car ownershi...
