Preparation method of hydrophobic chemical group modified waterproof glass

Abstract

The invention relates to a preparation method of hydrophobic chemical group modified waterproof glass. The preparation method comprises the following steps: (1) preparation of a Pirahan solution: preparing a Pirahan solution with strong oxidizing property by adopting H2O2 and concentrated H2SO4; (2) preparation of a CH3 monomolecular layer surface reaction liquid: preparing a CH3 monomolecular layer surface reaction liquid by using dimethyl octadecylchlorosilane and an n-hexane solution; and (3) preparation of a self-assembled molecular layer: sequentially dipping clean glass into the solutions to prepare a glass surface rich in CH3 on the surface. The method of the invention has the advantages that 1) the static water contact angle of the glass surface is increased from 45 degrees to 110degrees, and a strong hydrophobic surface is formed, so that the glass has the remarkable advantages of water resistance, fog resistance, snow resistance, pollution resistance, adhesion resistance, oxidation resistance, corrosion resistance, self-cleaning, current conduction prevention and the like; and 2) the method is simple in experimental steps, simple and convenient to operate and relativelyhigh in efficiency, has good application value and wide application space, and has extremely wide application prospect in the fields of scientific research, production, life and the like.

Description

technical field [0001] The invention relates to a method for preparing waterproof glass modified by hydrophobic chemical groups, and belongs to the technical field of engineering materials. Background technique [0002] Waterproof glass is relatively common in the market, but there are still some problems in its actual use. First, the hydrophobic rainproof agent is to coat hydrophobic polymer materials on the surface of the glass to form a polymer coating. The self-weight of the glass makes the water droplets slide down, which has the effect of waterproofing, but the water droplets cannot slide down when they are very small, resulting in dense water droplets on the glass, which reduces the clarity of the glass, and the stability is poor, requiring repeated maintenance; second, hydrophilic waterproof Due to the uneven local water film, it is easy to cause deformation of the surface image and affect the use effect; third, the superhydrophobic waterproofing agent is composed of...
