Abstract

The invention relates to a preparation method for a VOC basalt fiber. In the invention, a low-VOC polyolefin composite material is prepared by introducing nanometer TiO2 and improving basalt fiber VOCunder photo-catalytic effect; a rare earth element acts on the surface of the basalt fiber, so as to attach more oxygen-bearing active groups to the fiber surface; as an intermedium, the rare earth element is capable of boosting the chemical bond connection between the basalt fiber surface and the polyolefin material and promoting the mechanical property of the VOC basalt fiber; the VOC basalt fiber according to the invention is beneficial to the promotion of physical properties of the polyolefin composite material.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a preparation method of VOC basalt fibers. Background technique [0002] For a long time, basalt fiber has been widely used in polymer materials. Basalt fiber toughened and reinforced polyolefin is a popular technology developed by new research in recent years. [0003] In view of this reason, the applicant synthesized a self-made new basalt fiber to modify polyolefin, which has better physical properties than commercially available basalt fiber directly modifying polyolefin, and VOC performance has also been greatly improved. Related documents It has not been reported in the report, which greatly expands the application field of polyolefin composite materials and has very practical significance. Contents of the invention [0004] The purpose of the present invention is to provide a preparation method of VOC basalt fiber, to solve the problem of low physical propert...
