Abstract
The invention discloses a continuous basalt fiber surface treating agent and a preparation method thereof. The surface treating agent mainly comprises a film-forming agent, a lubricating agent, a coupling agent and a compatilizer. According to the invention, polypropylene grafted maleic anhydride is used as an interfacial compatibilizer, on one hand, MAH can be subjected to an esterification reaction with the surface of the fiber to reduce the polarity of the fiber, and MAH and the fiber are combined together through chemical bonds; and on the other hand, MAH can react with macromolecular freeradicals in polypropylene groups to be embedded into a matrix, so that the fibers and the matrix are connected through PP-g-MAH to form strong interface bonding. Meanwhile, the silane coupling agentis added, so that the affinity and the interface bonding force of PP and fibers are promoted, the process performance of the fibers is improved, and the fiber performance conversion rate and the composite material performance are ensured to be at a relatively high level. The preparation method is mainly used in the field of interface modification of thermoplastic resin and basalt fibers, and can give full play to the excellent effect of the basalt fiber reinforced thermoplastic resin-based composite material.
Description
technical field [0001] The invention relates to a preparation method of a surface treatment agent when continuous fibers are combined with thermoplastic resins, more particularly a surface treatment agent between continuous basalt fibers and polypropylene resin and a preparation method thereof. Background technique [0002] Continuous fiber-reinforced thermoplastic resin-based composites have developed rapidly in recent years due to their advantages such as high performance, fast molding speed, recyclability and recycling. Basalt fiber is the fourth largest high-performance fiber after carbon fiber, aramid fiber and ultra-high molecular weight polyethylene fiber, and it is one of the high-tech fibers that my country focuses on. my country is one of the main production and application countries of basalt fiber. However, at present in my country, basalt fiber is mainly used in thermosetting resin-based composite materials. There are no mature basalt fiber and composite materia...
