Problems solved by technology

When applied to car interiors such as car dashboards and door panels, the surface is easily scratched, which will directly affect the appearance of the car, which seriously affects its application in car trims; at the same time, polypropylene products are easy to scratch during the injection molding process. The force on the ejection part is relatively concentrated, and the whitening phenomenon occurs at the stressed part, that is, the top white phenomenon, which leads to the unqualified appearance of the product; some special structures such as clamping feet are easy to be stressed during use of some polypropylene products. Whitening and cracking

Embodiment Construction

[0017] specific implementation

[0018] Below in conjunction with embodiment, the present invention is described in further detail.

[0019] In the composite material formula of the embodiment and the comparative example, the polypropylene is a copolymerized polypropylene produced by Shanghai Petrochemical Co., Ltd., the trade name is M2600R, and its melt flow rate is 26g / 10min (test condition: 230 ° C × 2.16Kg) Described polyethylene wax is the CERALENE efficient polyethylene wax that Poland EUROCERAS company produces, and trade name is 882, and density is at 0.93g / cm 3 ; The polyethylene mentioned is LLDPE7042 produced by Qilu Petrochemical Company, and its melt index is 2.0g / 10min (test condition: 230°C×2.16Kg). The main antioxidants are DSTP produced by British ICE Company, whose chemical name is octadecyl thiodipropionate, and 3114 produced by Ciba Company, whose chemical name is 3,5-di-tert-butyl-4-hydroxybenzyl diethyl phosphate ester. The auxiliary antioxidant is 16...

Abstract

The invention discloses a high-fluidity and stress-resistance whitening modified polypropylene composite material and a preparation method thereof. The composite material is prepared from the raw materials as follows: by weight, 79% to 94% of polypropylene, 0.5% to 5% of polyethylene wax, 5% to 15% of polyethylene and 0.1% to 2% of antioxidants. In actual applications, the prepared modified polypropylene composite material maintains the fluidity of the polyethylene wax and modifies the stress-resistance whitening performance of the polyethylene simultaneously by using the lubricity of the polyethylene wax and the good compatibility of the polypropylene and combining synergistic modification of the polyethylene. The composite material can be used for manufacturing products having high demands of the fluidity and stress-resistance whitening.

Description

technical field [0001] The invention relates to a high-flow, stress-whitening-resistant modified polypropylene composite material, which is a modified polypropylene material with simple process and good comprehensive performance, and can be used to prepare some high-flow, stress-whitening-resistant modified polypropylene materials. products. Background technique [0002] Polypropylene is one of the five general-purpose plastics. Due to its rich source of raw materials, low price, easy processing and excellent overall performance, it has a wide range of uses and has become the fastest-growing variety of general-purpose resins. It is widely used in automotive interior and exterior decoration of products. When applied to car interiors such as car dashboards and door panels, the surface is easily scratched, which will directly affect the appearance of the car, which seriously affects its application in car trims; at the same time, polypropylene products are easy to scratch duri...
