Problems solved by technology

This kind of snow melting coating has a short service life, poor wear resistance and anti-skid effect
The second type is to adsorb the snowmelt substance on the porous load material, then add the load material to the modified emulsified asphalt, and spray it on the road surface to form a snowmelt coating. The slow release effect of this form of snowmelt coating is better than the first one. At the same time, adding a modifier to the emulsified asphalt enhances the wear resistance of the coating. However, in rainy areas, the snow-melting substances in the coating are easily taken away by rainwater, which makes the coating lose the snow-melting effect, and the water-based material sticks to the road surface. Poor adhesion, not suitable for heavy traffic roads

preparation example Construction

[0089] The preparation method of the above-mentioned long-term environment-friendly self-melting ice and snow coating for pavement is realized by the following steps:

[0090] Step 1: adding 3-10 parts by weight of coating material into 90-130 parts by weight of solvent, stirring evenly at room temperature and then standing for 24 hours to completely dissolve the coating material in the solvent to prepare a coating material solution;

[0091] Pass the snowmelt material through a 40-90 mesh sieve, then put the screened snowmelt material into the bottom spray fluidized bed coating machine, use the bottom spray coating method to evenly wrap the coating material on the surface of the snowmelt material, so that the snowmelt A continuous film of coating material is formed on the surface of the substance;

[0092] After the coating is completed, the snow-melting substance coated with the coating material is passed through a 20-70 mesh sieve, and then additives are added to obtain the...

Abstract

The invention relates to a long-acting environment-friendly ice-snow melting pavement coating and a preparation method and a using method of thereof. A snow-melting coating formed by spraying modified emulsified asphalt mixed with a porous carrier material absorbing a snow-melting substance onto a road surface can be taken away by rainwater so as to lose a snow-melting effect. The preparation method comprises the following steps: wrapping a snow-melting substance uniformly with a coating material so as to form a layer of continuous coating material thin film on the surface of the snow-melting substance, adding epoxy resin, an active diluent, a non-active diluent, a silane coupling agent, black paste, an accelerant and quartz sand, performing stirring uniformly, and then adding an epoxy resin curing agent to obtain a long-acting environment-friendly ice-snow melting pavement coating material. According to the preparation method, the snow-melting substance is wrapped with a high-molecular thin-film material so that the snow-melting substance has a better slow-release effect, the snow-melting life of the ice-snow melting coating is prolonged, the ice-snow melting function of a road can last for more than one year, and the coating is suitable for southern rainy regions.

Description

technical field [0001] The invention relates to a pavement coating material, in particular to a long-acting and environment-friendly pavement self-melting ice and snow coating and a preparation method and application method thereof. Background technique [0002] The snow and ice on the road surface in winter greatly reduces the adhesion coefficient of the road surface, which has a serious adverse effect on the smoothness of the road and driving safety. At present, the traditional snow and ice removal methods mainly include artificial, mechanical snow removal and snow removal by spreading deicing agent. Traditional snow and ice removal methods are widely used, but these methods are post-event snow removal technologies, which cannot effectively ensure road safety, especially in alpine regions and harsh weather conditions. Once snow and ice accumulate on the road, it is easy to cause traffic accidents or road interruptions. At present, the new active deicing and snow pavement...
