Abstract

The invention belongs to the scientific and technical field of composite materials, and discloses a modified pultrusion composite material and a preparation method thereof. The material is prepared from the following components in parts by weight: 100 parts of resin, 10-200 parts of a diluter, 0-80 parts of a filler, 0.1-2 parts of an initiator, 0.1-2 parts of a lubricant, 0.1-1 parts of a release agent and 200-1200 parts of inorganic fiber. Compared with the prior art, a fluorine-containing processing agent PPA (Polyphthalamide) is primarily used in the pultrusion composite material in the invention, so that pultrusion composite material can be effectively reduced, and the production period can be shortened. The fluorine-containing processing agent PPA is wide in application and good in effect in production of the pultrusion composite material, and part of the release agent can be replaced, and the content of the filler can be increased, so that the cost is effectively lowered.

Description

Technical field [0001] The invention belongs to the field of composite material science and technology, and relates to a modified pultrusion composite material and a preparation method thereof. Background technique [0002] In the field of pultrusion composite materials, especially when it comes to vinyl resin pultrusion operations, many manufacturers and companies have developed a series of mold release agents for different resins, such as CHEM-TREND, AXEL, Henkel Loctite, and vinyl resin mold release agents. Both have formed their own brand names. But it is expensive, and when the resin is required to be diluted, filled and modified, due to the large performance difference between the diluent, filler and the matrix resin, the use of the release agent of the directional brand has a poor release effect on the product, and Fluctuations in the normal range of pultrusion mold temperature can easily lead to uneven resin polymerization, sticky molds or products have scratches, block ...
