Problems solved by technology

[0003] The current anti-icing coating generally has the problem of poor bond strength with the road surface and short-term release of snow-melting agent; poor bond strength, the coating structure will be destroyed under the rolling of the vehicle load; and the release speed of snow-melting agent is fast , in the subsequent low-temperature ice and snow weather, no or a small amount of snow-melting agent will play the role of melting snow and suppressing ice; the effect of long-term stable release cannot be achieved, and the durability is poor
Facing the winter climate with continuous low temperature weather in the central region or other regions, the continuous ice suppression effect in winter cannot be guaranteed

Abstract

The invention discloses a long-term hydrophobic anti-icing coating, which comprises material A, material B and paraffin powder, wherein material A includes polyurethane, long-term hydrophobic anti-icing agent and polyurethane curing agent; material B includes water-based epoxy resin and water-based epoxy resin curing agent. The long-acting hydrophobic ice-suppressing coating obtained in the present invention can effectively inhibit the formation of ice layers on the road surface in freezing, rainy and snowy weather, and can also exert the effects of melting, destroying and thinning the ice layers in extremely bad weather ; And it still releases the deicing agent continuously under the traffic load on the road surface, and plays a long-term and stable role; this long-term and stable anti-icing coating can be directly adhered to the asphalt pavement, and rolled on the asphalt pavement, effectively reducing the freezing disaster of the road surface , is of great significance to driving safety in ice and snow weather.

Description

technical field [0001] The invention belongs to the field of road engineering, and in particular relates to a long-acting hydrophobic ice-suppressing coating and a preparation method thereof. Background technique [0002] The increasingly severe ice and snow weather in winter has had a great impact on road safety. Major traffic accidents often occur on road sections that are frozen due to ice and snow. How to remove the ice layer on the road surface or suppress the ice formation on the road surface is an urgent problem in the road field at present. In the past, the deicing method of road surface often used direct spraying of salt deicing agent and mechanical snow removal, which not only required a lot of manpower and material resources, but also caused damage to the surrounding environment. The existing self-stress elastic pavement technology at this stage is to mix rubber particles into asphalt concrete, and use the strain of the material to passively suppress ice, but the...
