Long-acting hydrophobic anti-ice coating and preparation method thereof

Abstract

The invention discloses a long-acting hydrophobic anti-ice coating which comprises a material A, a material B and paraffin powder, wherein the material A includes polyurethane, a long-acting hydrophobic anti-ice agent and a polyurethane curing agent; the material B includes a water-borne epoxy resin and a water-borne epoxy resin curing agent. The long-acting hydrophobic anti-ice coating disclosedby the invention is capable of effectively preventing pavement from icing under frozen, rainy and snowy weather and is capable of achieving the effects of thawing and damaging the ice layer and thinning the ice layer under extremely severe weather; a snow thawing agent is continuously released under the vehicle load on pavement and is capable of exerting a long-acting stable effect; after such a long-acting hydrophobic anti-ice coating is directly adhered to the bituminous pavement or is roll-coated on the bituminous pavement, the freezing disaster of pavement can be effectively reduced; the long-acting hydrophobic anti-ice coating has a great significance in guaranteeing traffic safety under icy and snowy 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...

AI Technical Summary

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
