Abstract

The invention provides a glass fiber soakage agent. The glass fiber soakage agent is suitable for an extrusion and injection moulding process. The glass fiber soakage agent is prepared from, by mass,0.10-3.00% of a silane coupling agent, 2.00-25.00% of a film forming agent, 0-1.00% of a plasticizer, 0.01-2.00% of a lubricating agent, 0.01-2.00% of a pH regulating agent and 67.00-97.88% of water;the film forming agent is a mixture of a first film forming agent and a second film forming agent, and the mass ratio of the first film forming agent to the second film forming agent is 10:1-1:8. Produced glass fiber twistless roving coated with the soakage agent is suitable for production of glass fiber reinforcement thermoplastic plastic.

Description

technical field [0001] The invention relates to a glass fiber sizing agent and its preparation method and application, in particular to a glass fiber sizing agent suitable for extrusion and injection molding processes and its preparation method and application. Background technique [0002] Various thermoplastic resin composite materials reinforced with glass fibers are widely used in transportation, electrical equipment, construction products and other industries. Extrusion and injection molding are a process in which glass fiber roving or chopped strands and thermoplastic resin are mixed and extruded through an extruder and cut into particles, and then these plastic particles are injection-molded to obtain final products. Extrusion and injection molding processes are a major processing technology for thermoplastic composites. [0003] At present, although the existing glass fiber sizing for extrusion and injection molding processes in the industry meets the needs of glass...
