Abstract

The invention discloses an environment-friendly tung-oil-based resin composite material and a preparation method thereof. Specifically in a process of preparing a fiber-filled resin composite material, natural tung oil and a derivative thereof are used as a resin raw material for replacing or partially replacing petroleum-based resin, and content of a renewable material in a polymer / fiber composite material aims to be increased. The environment-friendly tung-oil-based resin composite material is prepared by the following raw materials according to a weight percentage: 10%-99% of tung-oil-basedresin, 0-90% of industrial resin, 0-80% of an additive, 0.1%-20% of a curing agent, 0-20% of a catalyst, 1%-2% of talcum powder, and 2%-80% of fibers. The environment-friendly tung-oil-based resin composite material is simple and convenient in preparation process, strong in operability, easy to be industrialized, can be used for the fields of a frame of a solar cell module, a support, an environment-friendly building material, furniture, a floor, a building and decorating material, sports goods and the like, has the characteristics of green and environmental protection, light weight, energy conservation, resource conservation and the like, and has extensive application prospect.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a bio-based resin composite material and a preparation method thereof, in particular to an environment-friendly tung oil-based resin composite material and a preparation method thereof. Background technique [0002] Faced with the fact that the oil and natural gas we have relied on for a long time will be exhausted in the next one or two hundred years, people are trying to find biomass energy and materials that can replace oil and natural gas to achieve sustainable development. Plastic products widely used by people rely on petroleum resources for a long time, are difficult to biodegrade, and the production process is highly toxic, which has brought great pollution to the environment. Therefore, it is very necessary to develop new, environmentally friendly bio-based resins to replace or reduce the use of petroleum-based plastics. [0003] For thousands of...
