Abstract

The invention discloses a low-emission low-warpage long glass fiber reinforced polypropylene composite material suitable for an automobile skylight guide rail, a preparation method of the composite material and an application of the composite material in preparation of the automobile skylight guide rail. The low-emission low-warpage long glass fiber reinforced polypropylene composite material comprises the following raw materials in parts by weight: 30-60 parts of polypropylene, 40-70 parts of continuous glass fibers, 3-10 parts of a compatilizer, 0.1-1.5 parts of an antioxidant, 0-1 parts ofa lubricant, 8-20 parts of a thermoplastic elastomer, 0.2-2 part of a nucleating agent, 0.5-10 part of tetrapod-like zinc oxide whiskers and 0.2-3 part of a deodorant. The deodorant comprises a porousaluminum-silicon compound, and the pore diameter of the deodorant is 0.05-20 [mu]m. The preparation method comprises the following steps: uniformly mixing polypropylene, a compatilizer, an antioxidant, a nucleating agent, dried tetrapod-like zinc oxide whiskers and a selectively added lubricant to prepare master batch, blending the master batch with a thermoplastic elastomer and a deodorant, carrying out melt extrusion, and finally, carrying out continuous glass fiber impregnation and coating.

Description

technical field [0001] The invention relates to the technical field of polypropylene composite materials, in particular to a low emission and low warpage long glass fiber reinforced polypropylene composite material suitable for automobile sunroof guide rails and its preparation method and application. Background technique [0002] With the rapid development of the national economy, high-performance, low-cost thermoplastic resin-based composite materials have been widely used. It is an effective shortcut for the development of new materials to prepare fiber-reinforced thermoplastic resin-based composites (new structural composites, functional composites, etc.) by adding reinforcing fibers to thermoplastic resins and modifying the resins. This has become the consensus of the scientific and technological circles and the industry circles, and it is also the best technical route to realize the engineering of general-purpose plastics, the functionalization of engineering plastics,...
