Abstract

The invention provides a resin composition as well as a preparation method and application thereof. The resin composition comprises the following components in parts by weight: 50-70 parts of vinyl ester resin, 5-15 parts of a hydrophobic group-containing compound, 2-10 parts of nano titanium dioxide and 0.5-3 parts of a curing agent, the hydrophobic group-containing compound comprises any one or a combination of at least two of a polyoxypropylene compound, a polysiloxane compound or a fluorocarbon compound. And mixing the vinyl ester resin, a hydrophobic group-containing compound, nano titanium dioxide and a curing agent to obtain the resin composition. According to the resin composition provided by the invention, the specific vinyl ester resin, the hydrophobic group-containing compound and the nano titanium dioxide are compounded, so that a material comprising the resin composition is excellent in mechanical property, and self-cleaning can be realized.

Description

Technical field [0001] The present invention belongs to the field of functional material technology, specifically relates to a resin composition and preparation method and use thereof. Background [0002] The pultrusion process is a method of continuous production of composite profiles, which is usually a continuous glass fiber bundle, belt or cloth impregnated with resin glue, etc., under the action of traction, cured and molded by a hot mold, so as to continuously produce composite profiles of unlimited length. This process is particularly suitable for the production of VARIOUS cross-sectional shapes of FRP profiles such as rods, tubes, solid profiles and fasting profiles. The main raw materials for completing the pultrusion process include resin matrix, reinforcing materials and auxiliary materials. Among them, as an important part of the profile after curing, the chemical properties and mechanical properties of the cured resin matrix significantly affect the process difficul...
