Preparation method of rubber recycled powder modified fluorine-containing acrylate polymer coating

Abstract

The invention discloses a preparation method of rubber recycled powder modified fluorine-containing acrylate polymer coating, comprising: dissolving acrylate monomer and fluorine-containing acrylate monomer in a first solvent and reacting to prepare fluorine-containing acrylic acid Ester polymer solution, crushing and grinding clean recycled rubber materials to obtain rubber recycled powder with a particle size of 70-2000 μm, mixing fluorine-containing acrylate polymer solution, rubber recycled powder and a second solvent in proportion to obtain; the The hydrophobic contact angle of the coating prepared by the paint is greater than 150°. The preparation method of the present invention uses recycled rubber powder to modify the fluorine-containing acrylate polymer, thereby significantly improving its hydrophobic performance, and at the same time having good high temperature resistance, aging resistance, mechanical properties and adhesion properties, the preparation conditions are simple, and the process can be Control, the required equipment is common, the raw materials are easy to get and cheap, suitable for industrialized mass production, and has strong market competitiveness.

Description

technical field [0001] The invention relates to the technical field of coating preparation, and more specifically, relates to a preparation method of rubber recycled powder modified fluorine-containing acrylate polymer coating. Background technique [0002] The wetting behavior of a solid surface by a liquid is a very important feature in the field of polymer chemistry. The surface wettability can be expressed by the surface contact angle. In nature, many biological materials exhibit excellent surface wettability, such as lotus leaves, Rice leaves, butterfly wings, mosquito eyes, moth eyes, cicada wings, rose petals, gecko feet, desert beetles, spider silk and fish scales, etc., the contact angle of water droplets on the surface of these materials is often greater than 140°. When the contact angle between a water droplet and a solid surface is greater than 150°, the solid surface is called a superhydrophobic surface. [0003] Materials with superhydrophobic surfaces have a ...

Problems solved by technology

Based on the above two principles, there are currently many methods for preparing superhydrophobic coatings. However, due to its complicated preparation process, high raw material costs and production costs, and difficulties in mass production, there are currently many methods for preparing superhydrophobic coatings. The material method does not have the potential for industrial production, and the superhydrophobic coating materials prepared by most methods have the defects of poor stability, mechanical strength and consistency.
