Problems solved by technology

[0004] The purpose of the present invention is to provide an environment-friendly composite material to solve the problems of low elastic modulus, poor long-term temperature resistance, aging phenomenon and other phenomena that many glass fiber reinforced plastics often have when they are used in the above background technology, thereby reducing the glass fiber reinforced plastics. The service life leads to a faster replacement frequency of FRP, which in turn leads to the need to waste more resources for re-customization, which increases the cost of FRP use and reduces its environmental protection.

Abstract

The invention relates to the technical field of composite materials, in particular to an environment-friendly composite material which comprises silicon dioxide aerogel, aramid fibers, glass fibers, tetraethoxysilane, silicon carbide, diepoxypropane ethyl ether, vinyl resin, an initiator, an accelerant and a reinforcing agent. The preparation method comprises the following specific steps: adding silicon dioxide aerogel, aramid fiber and glass fiber into an emulsifying machine, filtering, evaporating excessive water, adding tetraethoxysilane, silicon carbide and diepoxypropane ethyl ether into a crusher, crushing, cleaning, mixing with vinyl resin for later use, and performing extrusion molding to obtain the composite material. And finally, mixing the mixture in each stage, filtering, drying, dehydrating, and extruding to form. Through comparison of a finished product experiment result and an existing finished product experiment result, the finished product is more durable than the existing finished product and is more difficult to damage, so that the replacement amount is reduced, the cost of a user is reduced, and the device is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an environment-friendly composite material. Background technique [0002] Composite materials are new materials that people use advanced material preparation technology to optimize the combination of material components with different properties. The matrix materials of composite materials are divided into two categories: metal and non-metal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon, etc. Reinforcement materials mainly include glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, etc. [0003] FRP is a common composite material. FRP is also called GFRP, that is, fiber-reinforced plastics. However, many FRPs often have low elastic modulus, poor long-term temperature resistance, and aging phenomena when the...
