Problems solved by technology

However, if the low surface energy liquid compound is lower than the rough substrate surface due to evaporation or side leakage, the low adhesion of the coating will disappear
In addition, the choice of rough substrates is limited to special materials that match the physical and chemical properties of low surface energy liquid compounds, which also restricts the application of this type of structural antifouling materials

Abstract

The invention belongs to the field of novel polymer functional materials, high-performance polymer structural materials and polymer coating materials, and discloses a low-adhesion antifouling coatingfor crude oil and a preparation method of the low-adhesion antifouling coating. The coating comprises 10-95 wt% of polymer resin or emulsion, 0-50 wt% of cross-linking component, 0-20 wt% of low-surface energy component and the balance being solvent or water. Without any adhesion trace, crude oil slips down the surface of the coating when being in contact with the coating. The coating has combination property such as good transparency, hardness, adhesiveness, flexibility and corrosion resistance, and is applicable to industrial equipment for spray-coating, dip-coating and blade-coating and corresponding processes, and applied to various basic materials such as glass, metal, woodware, ceramics, polymers and textiles. With low adhesion to crude oil and wide applicability, the coating has good application prospects in various links of crude oil extraction, transportation, storage and processing.

Description

technical field [0001] The invention belongs to the fields of novel polymer functional materials, high-performance polymer structural materials and polymer coating materials, and in particular relates to an antifouling coating with low adhesion to crude oil and a preparation method thereof. Background technique [0002] According to relevant research by the International Energy Agency (IEA), crude oil will continue to be the main source of energy for human beings for at least the next half century. The high viscosity of crude oil has caused certain difficulties in various links such as mining, transportation, storage and processing. At present, most of the existing technologies or research are aimed at the improvement of oil components, such as heating crude oil, diluting, emulsifying, adding low-resistance additives, etc. However, these methods have problems such as large energy consumption, cumbersome process, and poor adaptability to different reservoirs. [0003] Desig...
