preparation example Construction

[0043] The present invention also provides a preparation method of a color durable anti-skid layer of nano-silica acrylate, comprising the following steps:

[0044] Step 1, uniformly disperse the nano-silica SP30S in the polyacrylate emulsion with an ultrasonic nano-material emulsification disperser.

[0045] In step 2, the emulsion obtained in step 1 is sealed and sealed to obtain a nano-silica-modified polyacrylate emulsion.

[0046] Step 3, mix the nano-silica acrylate emulsion obtained in step 2 with the color binder, stir evenly with a stirrer, and seal it for use.

[0047] Step 4, cleaning the road surface, removing foreign matter, dust and drying treatment of the pavement structure layer.

[0048] Step 5, mixing and stirring the emulsion prepared in step 3 with the curing agent, and coating the pavement treated in step 4.

[0049] Step 6, spread the colored ceramic particles, and evenly spread the ceramic particles on the road surface within 1-2 hours of coating in st...

Abstract

The invention provides a color durable anti-skid layer of nano silicon dioxide acrylate and a preparation method of the color durable anti-skid layer. A cementing material is modified by adopting nano-silica polyacrylic acid, so that the color durability of a pavement can be effectively improved, the color function of the pavement can be maintained, the pavement performance of the pavement can befully exerted on a special road section, and the accident rate can be reduced; the nano silicon dioxide is adopted to modify polypropionate, so that a color durability anti-skid wearing layer can effectively maintain the color durability of the pavement, prolong the service life of the pavement, reduce the maintenance cost of the pavement, give full play to the functions of a colored pavement, effectively induce traffic flow, increase the traffic capacity of a special road section and reduce traffic accidents.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a nano-silica acrylate color durable anti-skid layer and a preparation method thereof. Background technique [0002] The transportation industry is an important material production sector in my country's national economy. By the end of 2018, my country's highway mileage had reached 142,600 kilometers, ranking first in the world in terms of total mileage. However, with the gradual improvement of the transportation network, my country's China's highway accidents have also increased, and the number of traffic casualties remains high. In recent years, my country has adopted various measures to enhance the safety performance of expressways. Among them, more and more colored pavement anti-skid layers are used on special road sections. [0003] The colored asphalt anti-skid wear layer can significantly increase the warning effect of the road surface and reduce the accident rate ...
