Low-VOC and antistatic polypropylene material as well as preparation method and application thereof

Abstract

The invention relates to the technical field of high polymer materials, and discloses a low-VOC and antistatic polypropylene material as well as a preparation method and an application of the low-VOCand antistatic polypropylene material. 5-20% of an inorganic filler; 2 to 10 % of carbon aerogel; 1-5% of epoxy resin; 1-5% of a compatilizer; 0.1-2% of a composite photo-thermal stabilizer; 0.1-2% ofa colorant; 0.1-2% of a lubricant are melted and mixed to obtain the low-VOC and antistatic polypropylene material; the carbon aerogel is applied to plastic, the characteristics of the carbon aerogelare utilized, and the carbon aerogel, the epoxy resin and the compatilizer are reasonably proportioned to obtain the polypropylene composite material with excellent mechanical properties, VOC emission properties and antistatic properties, and the polypropylene composite material can be applied to parts of interior and exterior decorations of automobiles, and is excellent in touch and long-actingin dust prevention.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-VOC, antistatic polypropylene material and its preparation method and application. Background technique [0002] Polypropylene is a general-purpose thermoplastic with excellent comprehensive properties. It has the characteristics of low price, light weight, solvent resistance, easy recycling, and non-toxicity. It is the most important lightweight material for automobiles. It can reduce the weight of auto parts by about 40%. Quality, has been widely used in automotive interior parts, such as dashboards, door panels, pillars, bumpers, etc. [0003] In the prior art, the polypropylene material routinely sold in the market has an unpleasant smell when heated, and even emits an unpleasant smell at room temperature. It contains some additives, which may seep or gasify, affecting the health of users, especially black Polypropylene modified material. Since many black pa...

AI Technical Summary

Problems solved by technology

[0005] This application can suppress the volatilization of VOC to a certain extent, but the addition of nano-active zeolite and other adsorption materials increases the production cost, and the polypropylene products produced by the polypropylene composite material are still used after long-term use or in high-temperature environments. Can not effectively avoid the volatilization of VOC

[0006] CN108485075A discloses a special modified polypropylene for low-VOC automotive interior parts, including the following components: polypropylene, talcum powder, glass beads, release agent, antioxidant, lubricant, light stabilizer, low molecular weight Organic matter repellent, in which glass microspheres are used as gas adsorbents, which can adsorb fine molecular organic substances by controlling the partial rupture of glass microspheres, but the specific surface area of ​​glass microspheres is small, even if they are all broken, they can absorb low molecular weight The amount is also very small. In addition, the addition of glass beads will reduce the impact performance and rigidity of polypropylene modified materials. Usually, automotive interior materials also require excellent mechanical properties.

[0007] Similarly, automotive interior materials are also faced with the requirements of dustproof materials and good antistatic properties. In the prior art, antistatic properties are given to low-VOC polypropylene composite materials, usually by adding antistatic additives, but this will cause Increase the cost of raw materials, while the addition of antistatic agents may lead to a decline in other properties of the material
