Abstract

The invention discloses an integrated manufacturing material for an automotive glass lifter guide rail and a manufacturing method of the material. The material is prepared from 40-55 wt% of long glass fibers and the balance pure polypropylene. The integrated manufacturing material for the automotive glass lifter guide rail is in a columnar particle shape, the interiors of columnar particles are of Swiss-roll-shaped lamination structures, the lamination structures are formed by alternately rolling mixing blanketing layers and pure polypropylene layers, and the mixing blanketing layers are formed in the mode that after the long glass fibers and pure polypropylene fibers are mixed, wet-method deposition is conducted. The prepared particle material can quickly form a stable three-dimensional space structure in the injection molding process and is not easily influenced by the rotation speed of a screw of an injection molding machine, the long glass fibers are not easily broken, the mechanical property of a finished product is obviously improved, through the mixing blanketing layers and the lamination structures, the difficulty of an impregnation technology can be lowered, and the impregnation effect is improved. Through a needling technology, the stability of the mixing blanketing layers in the processing process can be obviously improved.

Description

technical field [0001] The invention relates to the field of long glass fiber reinforced polypropylene materials, in particular to a material for making guide rails of an integrated automobile glass lifter and a preparation method thereof. Background technique [0002] At present, automobile parts have been prepared with a large number of different lightweight materials, and thermoplastic composite materials such as PP plastics have become the main body of lightweight materials. Long glass fiber reinforced thermoplastic composite materials are easy to process and shape, high in strength and small in weight. The advantages of wear resistance and low cost are becoming the key areas of automobile lightweight research. [0003] There are four main types of long glass fiber reinforced thermoplastic composite (LFT) molding processes, namely LFT-D, LFT-E, LFT-G, LFT-S, LFT-D full name long / continuous glass fiber reinforced hybrid direct molding Process, this process uses a special...
