Abstract

The invention belongs to the field of new materials, and particularly relates to a super-hydrophobic-lubricating composite anti-icing coating with a porous structure and a preparation method thereof.The coating is composed of a foamed porous super-hydrophobic coating and a bionic joint lubricating liquid, and the super-hydrophobic-lubricating composite anti-icing coating of the super-hydrophobicfoamed porous structure is prepared by compounding low-molecular polybutadiene, polyacrylamide, waterborne polyurethane and alkyl ketene dimer and then heating and foaming p-toluenesulfonyl hydrazine.Blended components of the bionic joint lubricating fluid of the obtained coating and low-molecular-weight polybutadiene can significantly reduce the adhesive force of an ice layer, so that the adhesive force of the ice layer is reduced to 5 kPa or below, and an excellent ice-resistant effect is achieved.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a superhydrophobic-lubricating composite anti-icing coating with anti-icing effect. Background technique [0002] Freezing and cold weather will bring hundreds of millions of losses to our country every year, involving delays and losses in aerospace transportation, public transportation, infrastructure facilities, and even power transportation. The icing of the line will make the timely dredging of the power sector extremely challenging. As a big country with a large land and abundant resources, the impact of icing on the line is among the top in the world. In addition, the impact of icing on aircraft wings is also decisive. Severe icing can even cause the wings to stall and cause air crashes. In terms of roads, the improvement of travel safety also starts with the anti-skid and anti-icing of tires and rails. Icing has brought huge hidden dangers to people's property an...
