preparation example Construction

[0034] Preparation of premix: adding the required polypropylene, talc, Accurel XP100-60 water-absorbing masterbatch, antioxidant, lubricant, light stabilizer, and metal passivator into a high-speed mixer for high-speed stirring and mixing to obtain premix;

[0035] Melt blending extrusion: The obtained premix is ​​fed from the main feeding hopper into a parallel twin-screw extruder, so that all components are sheared and melt-blended in the parallel twin-screw extruder, wherein twin-screw extrusion The machining temperature is 180-200°C, and the cylinders are evacuated with a vacuum pump in the seventh and ninth sections respectively;

[0036] Obtainment of low odor and low VOC polypropylene composite material: cooling, drying and pelletizing the material strips from the parallel twin-screw extruder die to obtain low odor and low VOC polypropylene composite material.

[0037] The polypropylene can be purchased from Maoming Petrochemical PPK7726H.

Embodiment 1

[0038] Example 1: Preparation of low odor and low VOC polypropylene composites

[0039] Raw materials used: see Table 1.

[0040] Preparation of Accurel XP100-60 water-absorbing masterbatch: put the plastic foam carrier Accurel XP100-60 into the low-speed mixer, and then add water to the mixer according to the mass ratio of the foam carrier Accurel XP100-60:water=6:4 , then mix for 10-30 minutes. Stop the machine to check the particles. If the surface of the foamed carrier particles is dry and there is no free-flowing water, it can be cooled to room temperature and then unloaded and packaged to obtain Accurel XP100-60 water-absorbing masterbatch.

[0041] Mix the polypropylene, talc powder, Accurel XP100-60 water-absorbing masterbatch, antioxidant, lubricant, light stabilizer, and metal passivator that are weighed in proportion, and then add to the parallel twin-screw extruder from the main feeding port. Out of the machine, all the components are sheared, melted and extruded...

Abstract

The invention discloses a low-odor and low-VOC polypropylene composite material and a preparation method thereof. It consists of the following components: polypropylene 69.7-73wt%, talc 25wt%, Accurel XP100-60 water-absorbing masterbatch 1-4wt%, antioxidant 0.4wt%, lubricant 0.3wt%, light stabilizer 0.2wt%, The metal passivator is 0.1-0.4wt%; the Accurel XP100-60 water-absorbing master batch is the master batch formed by utilizing the plastic foam carrier Accurel XP100-60 water-absorbing treatment. The prepared low odor and low VOC polypropylene composite material has excellent odor level (odor level less than 3), and has low total carbon emission (total carbon emission is less than or equal to 30ug / g). At the same time, it also has the characteristics that the production and processing equipment does not need to be modified and the preparation process is simple.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-odor and low-VOC polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene thermoplastic resin raw materials have excellent comprehensive mechanical properties, convenient processing and low price, and are widely used in automobiles, electronic appliances, mechanical parts, clothing, etc. In practical applications, as people's health awareness continues to increase, consumers begin to pay attention to the air quality inside the car, so auto parts manufacturers are becoming more and more strict with product odor requirements. And polypropylene composite materials will release some unpleasant odors to varying degrees, mainly caused by the following aspects. First of all, the catalyst system used in the synthesis of polypropylene resin matrix contains some lipid compounds or alkane compounds with pungent odor. Se...
