Problems solved by technology

[0002] Traditional geopolymer raw materials are mostly non-renewable resources, not easy to degrade, and the pollution in the production process is relatively serious, which is not conducive to environmental protection and does not conform to the sustainable development strategy. It is necessary to develop environmentally friendly, pollution-free and renewable natural reinforcement materials
Coconut shell fiber is natural pollution-free, green and environmentally friendly, strong toughness, high strength, and wide source. It is an ideal natural reinforcement material, but coconut shell fiber is relatively hydrophilic, easy to rot, and poor in durability. The natural state is one or two It will degrade within a year, and it is not suitable for engineering projects with a long operating time, and it needs to be treated with anti-corrosion
Using chemical methods (such as acid or alkali treatment, coupling agent treatment, enzyme treatment, steam explosion, etc.) to treat the surface of coconut shell fiber can enhance its durability, but its durability is still insufficient for the operation life of important projects

Abstract

The invention relates to a preparation method of a natural coconut fiber reinforced epoxy resin composite fiber. The preparation method of the natural coconut shell fiber reinforced epoxy resin composite fiber comprises the steps of trimming the prepared coconut shell fiber into fiber segments with the length of 0.5-5 cm; mixing and stirring the fiber segments and molten epoxy resin for 10-20 minin a spherical stirrer according to the mass ratio of 5%-20%; coating a first layer of release agent on the inner surface of a mold, standing for 5-10min and waiting for solidification of the releaseagent, then coating a second layer of release agent on the surface of the first layer of release agent, and slowly injecting the composite resin melt into the mold after the two layers of release agents are completely solidified; sealing and vacuumizing the mold filled with the composite resin melt; and extruding the composite resin melt through an extrusion molding method, and manufacturing a molded composite fiber body. The preparation method of the natural coconut fiber reinforced epoxy resin composite fiber has the advantage of high durability.
