Description
Technical Field
The invention discloses a preparation method of a novel cushion layer for a road surface super-hydrophobic ice-suppressing coating, and belongs to the technical field of road engineering ice suppression.
Background
The adhesion between ice and the substrate presents drawbacks in the fields of traffic, transmission, aviation and coal, which create enormous losses in terms of economy and safety. In the aeronautical field, ice accumulated on the surface of the aircraft can change the shape of the aircraft, causing the aircraft to lose its stability. In the coal mining field, ice adhesion can cause wet coal to adhere to trams, resulting in a reduction in their load bearing capacity. In the traffic field, the adhesion of ice and the road surface reduces the skid resistance of the road surface, which can cause serious traffic accidents, and the related data show that severe weather conditions such as snowfall, freezing rain and the like can respectively improve the accident occurrence rate and the casualty rate by 84 percent and 75 percent.
The application research of the snow-melting ice-suppressing material and the asphalt mixture thereof mainly takes the material manufactured by Mafilon manufactured by Japan and Verglimit manufactured by Switzerland as research objects at present. Aiming at the phenomenon of snow accumulation and icing on the road surface in winter, various students at home and abroad research and prepare various snow melting and ice inhibiting materials and experience and methods worthy of learning and reference, and various treatment technologies for inhibiting road surface ice condensation, which are commonly used at home and abroad, can be generally divided into two major technologies, namely a passive road surface ice condensation inhibiting technology and an active road surface ice condensation inhibiting technology. According to different adopted specific measures, the technology for passively inhibiting the pavement ice-condensation is divided into a manual clearing method, a mechanical clearing method, snow-melting agent spreading, sand-spreading stone material spreading and the like; the technical measures for actively inhibiting the pavement ice are mainly adding a salt storage material into a pavement material to reduce the freezing point, adding a high-elasticity material into the pavement material to generate self-stress deicing, embedding an energy conversion system in the pavement material to perform deicing, and the like. And the ice inhibiting performance and road performance of the ice inhibiting material with different components and different contents are summarized by a plurality of test methods such as a freezing point test experiment, an ice and snow melting experiment, a corrosion test and the like, and the ice inhibiting material is applied to various natural environments and social environments to obtain certain performance. However, these methods also have certain disadvantages that limit their future development. The passive deicing construction is simple and convenient, the price is relatively low, but the efficiency is low, a large amount of manpower and material resources are consumed, and certain damage is caused to the structure; the active deicing is high in efficiency and has no obvious damage to the structure. However, the active deicing methods currently used in the market are generally relatively expensive, so that the superhydrophobic coating can be completely open in the methods. The super-hydrophobic ice-suppressing coating can melt ice for multiple times after one-time construction, does not harm the road surface, bridges, steel structure facilities, auxiliary facilities and the surrounding environment, can save labor and labor, and has the advantages of low carbon, environmental protection, economy and applicability, so that the trend of reducing the ice adhesion of the road surface by using the super-hydrophobic surface is a future research trend.
However, the super-hydrophobic coating has some problems in the current research. For example, although the super-hydrophobic coating has good hydrophobic properties, it has poor mechanical abrasion resistance, and thus is still a troublesome problem in practical road applications. In addition, the super-hydrophobic coating has weak adhesion to various substrates, and many scholars have studied and searched for the weak adhesion. This drawback is remedied mainly by two improvements, on the one hand by improving the preparation process of the superhydrophobic coating and on the other hand by increasing the adhesion to the substrate by means of adhesives, tie layers, etc.
Therefore, according to the content, the polyurethane foam with heat preservation and hydrophobic performance is selected as the cushion material between the super-hydrophobic coating and the pavement, and the cushion material is soaked, dried, embossed and the like to form the nano-filled porous continuous cushion with the inverted pyramid structure, so that the adhesion between the super-hydrophobic ice-suppressing coating and the matrix is improved, and the wear resistance of the super-hydrophobic ice-suppressing coating is improved.

The technical scheme of the invention is as follows: cleaning polyurethane foam, placing the cleaned polyurethane foam in a mixed solution of epoxy resin three-proofing paint, a curing agent and a diluent, soaking for a period of time, compressing the polyurethane foam into a basic soft cushion layer by a compressor, soaking the basic soft cushion layer by using a normal hexane solution of perfluorodecyl trichlorosilane after the rigidity is complete, obtaining a continuous porous cushion layer filled with nano particles after the drying is complete, and finally realizing an inverted pyramid-shaped microstructure by an embossing technology so as to further improve the binding power between the super-hydrophobic ice suppression coating and a matrix.
