Abstract

The invention discloses a polypropylene fiber continuous glass fiber blended thermal composite reinforcing material and a preparation method thereof. The preparation method comprises the following steps of (1), preparing the polypropylene fiber; (2), performing surface carboxylation of the polypropylene fiber; (3), modifying the surface of the glass fiber; (4), mixing the polypropylene fiber withthe glass fiber, namely mixing the polypropylene fiber and the glass fiber by means of a fiber self-weighing mixing system, controlling the humidity of a blending environment to 33-43%, and controlling the temperature of the blending environment to 20-30 DEG C; and (5), performing pressing forming, namely performing hot pressing forming on the polypropylene fiber and the glass fiber fabric which are accurately mixed. The preparation method has advantages of simple process, continuous production process, high production efficiency, simple equipment and high convenience in technique mastering. On one hand, the polypropylene fiber continuous glass fiber blended thermal composite reinforcing material has relatively high mechanical performance, and one the other hand, compared with a common immersion method, the blending method has an advantage of higher convenience in processing.

Description

technical field [0001] The invention belongs to the technical field of hybrid fiber composite materials, and in particular relates to a polypropylene fiber continuous glass fiber blended thermal composite reinforcing material and a preparation method thereof. Background technique [0002] The innovation and development of science and technology have promoted the continuous renewal and development of materials, and new materials have become the focus and key to promote and develop high-tech fields. Especially in the field of material modification and textile, people pay more and more attention to the innovation and requirements of new materials. Multi-component composite yarn refers to a new type of yarn prepared by two or more fibers through yarn processing technology. By changing the hybrid method and structure of the yarn, multi-component yarns with excellent mechanical properties can be obtained. Composite line realizes complementary advantages between fibers. On the bas...
