Abstract

The invention relates to a melt impregnation device for continuous long glass fiber reinforced POM (polyformaldehyde) production and an impregnation method. The melt impregnation device comprises a casing, a reaction tank and an impregnation tank, wherein a reaction tank glass fiber inlet is formed in the front end of the reaction tank, a reaction tank glass fiber outlet is formed in the rear end of the reaction tank, and the reaction tank is filled with a compatilizer; the impregnation tank comprises a die cavity, a resin lead-in channel inlet, a glass fiber inlet, a glass fiber outlet and a glass fiber dispersion impregnation rolling wheel; and the resin lead-in channel inlet, the glass fiber inlet and the glass fiber outlet are communicated with the die cavity respectively, the glass fiber dispersion impregnation rolling wheel is placed in the die cavity filled with melt POM resin. Compared with the prior art, the melt impregnation device and the impregnation method have the advantages that friction and bending loss of fiber glass filaments can be reduced, the impregnation speed is increased, the productivity is improved, and the processing cost is reduced simultaneously; and the compatilizer is used for glass fiber pretreatment, so that the binding force and the impregnation effect between the glass fiber and the resin are improved, and finally, the product performance is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of modification and processing of new materials, and in particular relates to glass fiber bundle reactive melting and infiltration equipment and an infiltration method for continuous long glass fiber reinforced POM production. For the production of continuous long glass fiber reinforced thermoplastic POM. Background technique [0002] The glass fiber length of the glass fiber reinforced thermoplastic POM produced by the traditional modification method is generally less than 0.5mm, and the average length is 2-3mm. The main damage of the product is that the glass fiber is pulled out from the matrix. If it is pulled out from the matrix resin, the strength of the product will be lower. At the end of the last century, continuous long glass fiber reinforced thermoplastic POM (LFT) began to emerge in the foreign modified POM industry. Compared with traditional glass fiber reinforced thermoplastic POM, the glass f...
