Epoxy resin matrix complex additive and preparation method thereof and modified polypropylene material

Abstract

The invention discloses an epoxy resin matrix complex additive and a preparation method of the additive and a modified polypropylene material. The preparaiton method comprises the steps of weighing epoxy resin, nylon 6, methanoic acid according to certain mass percentages, dissolving nylon 6 by adding into methanoic acid, and then adding epoxy resin to mix uniformly, dropwisely adding excess water into the mixture till no more white precipitate is generated, filtering and drying the white precipitate to obtain a white lump, and smashing the lump into white powder. The white powdery epoxy resin-nylon 6 complex additive prepared with the method of the invention has a good reinforcement effect on polypropylene, and the modified polypropylene obtained has good rigidity and strength and can beprocessed into automobile spare parts, electronic and electrical parts and the like. Furthermore, the preparation process of the epoxy resin matrix complex additive and the modified polypropylene material provided in the invention is simple and easy to operate, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a compounding auxiliary agent and a preparation method, and a modified polypropylene material obtained by using the compounding auxiliary agent. Background technique [0002] Polypropylene is a widely used resin with good mechanical properties, but its rigidity and strength are not high enough to meet the requirements of engineering materials. In order to improve the rigidity and modulus of polypropylene, inorganic fillers and glass fibers are usually added to it. Inorganic fillers and glass fibers are inorganic materials, and they are not easy to combine with organic materials such as polypropylene. Epoxy resin is an organic material and has excellent adhesion, high rigidity and strength. Chinese patent CN 02155007.7 reports that the material prepared by adding epoxy resin to polypropylene has good rigidity and strength, but when adding viscous liquid epoxy resin to the equipment and mixing with polypropylene, the mucus is e...

Chinese patent CN 02155007.7 reports that the material prepared by adding epoxy resin to polypropylene has good rigidity and strength, but when adding viscous liquid epoxy resin to the equipment and mixing with polypropylene, the mucus is easy to stick to hands, sticky Inconvenience in operation such as equipment and mucus leakage

So far, it has not been found that epoxy resin is added to nylon 6 by solution method to make powder compound additives and then used to modify polypropylene.
