Embodiment 1～2

[0024] This embodiment relates to a low emission and low odor glass fiber reinforced polypropylene composite material and its preparation method, the method is as follows:

[0025] Step 1, weighing the raw materials according to the weight ratio, each component and its data are shown in Table 1;

[0026] Step 2, the raw material polypropylene, glass fiber, compatibilizer and antioxidant weighed according to the weight ratio are added to the high-speed mixer in proportion and fully mixed, and then the above mixture is added to the extruder, and the extruder is passed through the extruder After plasticizing, extrude, draw, cool, and pelletize to 3-5mm long cylindrical particles, and finally obtain low-emission and low-odor glass fiber reinforced polypropylene composite materials. The temperature of the screw extruder is 100-220° C., and the rotation speed of the main engine is 300 rpm.

[0027] Among them, the polypropylene is provided by Sinopec Company, the brand is M60T; the...

Abstract

The invention discloses a low-emission low-odor glass-fiber-reinforced polypropylene material and a preparation method therefor. The material is prepared from the following raw materials in parts by weight: 35-80 parts of polypropylene, 15-60 parts of glass fibers, 1.0-5 parts of compatibilizer and 0.1-1.5 parts of antioxidant. According to the material and the preparation method therefor, hindered phenol and hindered amine polymers are adopted as the antioxidant, an obtained sample has the same excellent aging resistance as that of a control sample, and the sample prepared by the method has alower odor level and lower emission performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-emission and low-odor glass fiber reinforced polypropylene material and a preparation method thereof. Background technique [0002] Compared with steel and other metals, the modulus strength of polypropylene material is much lower than that of steel and other metals. Therefore, in the field of automotive materials, polypropylene materials need to use glass fiber, talcum powder and other filler materials to improve the strength and modulus, so that they can be used in The field of automotive materials to replace steel, and ultimately achieve the purpose of reducing the weight of auto parts. [0003] Due to its high strength and high modulus, glass fiber reinforced polypropylene materials are generally used in stressed structural parts. During the long-term service life of automobiles, glass fiber reinforced polypropylene materials will degrade due to the influence ...
