Embodiment 1

[0065] A wear-resistant super-hydrophobic coating, comprising resin A and resin B, wherein resin A comprises the following raw material components in parts by mass:

[0066] Hydrophobic epoxy resin 2.5g,

[0067] Curing agent 0.78g,

[0068] Thinner 3.3g;

[0069] Resin B includes the following raw material components in parts by mass:

[0070]

[0071] In this example, in resin A, the curing agent includes 0.32 g of diaminodiphenylmethane (DDM) and 0.46 g of polyetheramine D-400, and the diluent is ethyl acetate.

[0072] In this example, in resin B: the curing agent is 0.52g diaminodiphenylmethane (DDM) and 0.74g polyetheramine D-400, the diluent is ethyl acetate, the filler is nanoscale aluminum oxide particles, and the nanoscale The average particle size of the aluminum oxide particles was 30 nm.

[0073] In this example, the used hydrophobic epoxy resin was prepared by the following method: 6.28g of γ-glycidyl etheroxypropyltrimethoxysilane (KH560), absolute ethano...

Abstract

The invention discloses a wear-resistant superhydrophobic coating and a preparation method thereof. The wear-resistant superhydrophobic coating comprises resin A and resin B, wherein the resin A is prepared from, by weight, 2.5g of hydrophobic epoxy resin, 0.6g-1.3g of a curing agent and 3g-4g of a diluent; the resin B is prepared from, by weight, 4g of hydrophobic epoxy resin, 0.96g-2.08g of a curing agent, 16g-60g of a diluent and 4g-16g of a filler. The preparation method includes: successively coating a substrate with the raw materials corresponding to the resin A and the resin B. The wear-resistant superhydrophobic coating has the advantages of good superhydrophobic performance, good linear wear resistance, good corrosion resistance, good adhesive tape adhesion resistance, good particle impact resistance and the like and is suitable for large-scale preparation and industrial application.

Description

technical field [0001] The invention belongs to the field of preparation of coatings, in particular to a wear-resistant super-hydrophobic coating and a preparation method thereof. Background technique [0002] The superhydrophobic phenomenon with a contact angle greater than 150° and a rolling angle less than 10° has attracted widespread attention in recent years. It has strong applicability in the fields of self-cleaning, anti-icing, oil-water separation, etc., and studies have shown that the preparation of superhydrophobic The surface usually needs to satisfy two conditions: low surface energy and micro-nano secondary structure of the surface. [0003] Among the many known methods, the prepared superhydrophobic surfaces are difficult to be applied on a large scale due to their poor properties such as wear resistance and corrosion resistance. For coatings, it cannot maintain its own properties during friction like superhydrophobic blocks depending on its thickness, or impr...
