Embodiment Construction

[0012] The invention provides a method for preparing a cushion layer for a novel pavement superhydrophobic ice-suppressing coating, which is characterized in that: the specific steps of the preparation method are as follows:

[0013] (1) Soak polyurethane foam with a thickness of 1.5-3cm in the mixed solution of epoxy resin conformal paint, curing agent and diluent for 5-10 minutes, and the weight ratio of epoxy resin conformal paint, curing agent and diluent is 5:1:20. After soaking, take it out and manually squeeze to remove excess adhesive, and compress it into a compact cushion layer under a pressure of 20MPa through a compressor;

[0014] (2) After waiting for the cushion layer to be fully rigid, soak it in the n-hexane solution of perfluorodecyltrichlorosilane for 10 minutes, take it out and wash it several times with n-hexane, and dry to obtain a hydrophobic cushion layer without filling;

[0015] (3) Place the hydrophobic unfilled cushion layer in a well-mixed solutio...

Abstract

The invention discloses a preparation method of a cushion layer for a novel pavement super-hydrophobic ice-inhibiting coating, belongs to the technical field of road engineering ice inhibition, and solves the problems of poor pavement performance and weaker adhesive force with a matrix of the existing super-hydrophobic ice-inhibiting coating. The preparation method comprises the following steps: firstly, soaking, compressing and drying polyurethane foam to prepare a non-filling soft cushion layer with a hydrophobic property, then putting the non-filling soft cushion layer into a fully mixed solution of ethanol, titanium dioxide and perfluorooctyltriethoxysilane, drying to obtain a continuous porous cushion layer filled with nano particles, and finally, preparing the continuous porous cushion layer with the inverted pyramid structure through an embossing technology. The prepared cushion layer can be used for preparing a super-hydrophobic ice-inhibiting coating, the binding power betweenthe super-hydrophobic ice-inhibiting coating and a matrix is improved, and the wear resistance of the super-hydrophobic coating is improved.

Description

technical field [0001] The invention relates to a method for preparing a novel pavement superhydrophobic ice-suppressing cushion layer, which belongs to the technical field of road engineering ice-suppressing technology. Background technique [0002] Adhesion between ice and substrates has disadvantages in the fields of transportation, power transmission, aviation and coal, and these disadvantages have great economic and safety losses. In aviation, the accumulation of ice on the surface of an aircraft can change the shape of the aircraft, causing the aircraft to lose its stability. In coal mining, the cementitious nature of ice can cause wet coal to cling to trams, reducing their carrying capacity. In the field of transportation, the adhesion of ice to the road surface reduces the anti-skid performance of the road surface, which will also lead to serious traffic accidents. According to relevant data, severe weather conditions such as snowfall and freezing rain can increase ...
