Embodiment 1

[0016] According to the mass percentage, 23-85% of thermosetting polymer prepolymer butylene terephthalate with reactive active centers, 9-77% of surface functionalized nanoparticles ferric oxide, and 0-5% of curing agent methyl ethyl ketone peroxide .

[0017] Put the glass sheet in deionized water for ultrasonic cleaning, and then oxygen plasma cleaning for 5 minutes. Mix butylene terephthalate and ferric iron tetroxide evenly by mechanical stirring, and take methyl ethyl ketone peroxide with a concentration of 1.5%. Add it to the mixture, spray it on the pre-cleaned glass, put it in an oven and bake it at 65°C for 10-50min to cure. The contact angle of the cured coating material was measured to be 153°. Almost unchanged after a few days.

Abstract

The utility discloses a coating material which is prepared from a thermosetting high molecular pre-polymer having a reaction active center and surface functionalized nano-particles under the action of a curing agent, wherein the mass percentage contents of all the components therein are as follows: 23-85% thermosetting high molecular pre-polymer having the reaction active center, 9-77% surface functionalized nano-particles, and 0-5% curing agent. The preparation method of the coating material disclosed in the invention is simple in process and free of complex parameter control; the preparation method causes no pollution during preparation and thereby is environment-friendly; and simultaneously, the coating material prepared in the invention is stable in super hydrophobicity, good in repeatability, and also low in cost; therefore, the coating material has excellent industrial application prospect.

Description

technical field [0001] The invention belongs to the field of engineering technical materials, and in particular relates to an organic and inorganic nanometer coating material. Background technique [0002] Among composite materials, fiber reinforced materials are the most widely used and used in the largest amount. They are characterized by small specific gravity, high specific strength and specific modulus, and are representative of inorganic-organic composite materials. Due to the characteristics of light weight, high strength, convenient processing and forming, excellent elasticity, chemical corrosion resistance and good weather resistance, composite materials have gradually replaced wood and metal alloys, and are widely used in aerospace, automobiles, electronics, construction and other fields. Due to the special properties of nanomaterials, such as the small size effect, the surface effect provides a new research direction for the study of composite materials. The wat...
