Abstract

The invention discloses a formula and preparing method of a carbon fiber sizing agent for reinforcing polypropylene. Compared with traditional solvent type sizing agents, the prepared sizing agent has the advantages of being low in toxicity, low in cost, low in pollution and the like with water serving as the continuous phase. Besides, the sizing agent is suitable for a polypropylene resin matrix and solves the problem of poor cohesiveness between carbon fiber and polypropylene resin. When the sizing agent is used for sizing, the post processing capacity of carbon fiber is improved remarkably, the cohesiveness of the interface between carbon fiber and polypropylene matrix resin is high, and the macroscopical mechanical strength of a carbon fiber / polypropylene composite material is improved to a large extent.

Description

Technical field [0001] The invention involves a recipe and preparation method of a lotion of lactating carbon fiber slurry, which specializes in the formula and preparation method of a mitro -oxidized graphene -modified emulsion carbon fiber slurry. Background technique [0002] Carbon fiber has excellent performance of high -ratio, high ratio, high temperature resistance, and corrosion resistance. It is used as an enhanced body for composite materials and is widely used in various fields.At present, the commonly used carbon fiber resin base composite material is mainly thermosetry resin.In the past two decades, with the rapid development of industry composite materials, the application of various industries has become more and more widely used.Harmic gas volatilization and waste recycling of thermosett resin composite materials are particularly tricky.The thermoplastic resin base composite material is recycled with its available, and the molding time of the product is short and ...
