Problems solved by technology

However, there is a serious problem in these long glass fiber reinforced polypropylene materials, that is, the smell and the total carbon emission are large, and in order to ensure other characteristics of the final product (such as preventing fiber pullout from affecting its mechanical properties), a variety of additives are added. Adjuvants lead to the volatilization of more toxic and harmful gases, seriously affecting its range of use on auto parts

Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] Weigh the raw materials according to the formulation amounts of each embodiment in the following table 1, add the weighed samples into the high mixer, rotate at a speed of 800 rpm, and mix for 20 minutes. After fully mixing, the premix is ​​obtained, and then the premix is The mixture is transferred to a twin-screw extruder, the extrusion temperature of the twin-screw extruder is 190°C, and the extrusion speed of the twin-screw extruder is 600 rpm, extruded and granulated to obtain a long Glass fiber modified polypropylene.

Abstract

The invention discloses long-glass fiber-modified polypropylene for an instrument panel skeleton. The long-glass fiber modified polypropylene consists of the following raw materials in parts by weight: 55-85 parts of PP resin, 8-14 parts of glass fibers, 8-25 parts of nano TiO2, 0.1-1 part of a coupling agent, 0.2-0.5 part of a hyper dispersant and 0.05-1 part of an odor absorbent. The long-glass fiber-modified polypropylene disclosed by the invention is less in odor and total carbon emission and more environment-friendly, and simultaneously has stronger mechanical properties and stability.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a long glass fiber modified polypropylene for instrument panel framework. Background technique [0002] With the continuous improvement of energy-saving and lightweight requirements of automobiles, the demand for plastics to be used in structural or semi-structural parts is increasing, which promotes the application of glass fiber reinforced polypropylene materials in automotive parts. The study found that in order to make the glass fiber play a good role in strengthening in polypropylene, the length of the glass fiber must be greater than its critical length, otherwise when the length of the glass fiber is less than the critical length, when the material is subjected to a certain load, the fiber will have It may be pulled out, and the strength of the fiber will not be fully exerted. The current long glass fiber reinforced polypropylene material has been developed by...
