Problems solved by technology

However, the adsorption of organic volatiles in plastics is less studied.
[0005] Under the existing technology, the low-VOC modification of polypropylene is mostly achieved by adding the adsorption effect of synthetic molecular sieves, which is costly

Abstract

The invention discloses a low-VOC polypropylene composite material and a preparation method thereof. The low-VOC polypropylene composite material comprises the following raw materials by weight: 45 to 79.5% of polypropylene, 12 to 30% of an inorganic filling material, 3 to 7% of a flexibilizer, 5 to 15% of calcined diatomite, 0.2 to 2% of a stabilizing agent and 0 to 5% of other additives. The invention has the advantages that 1, since the calcined diatomite is used as a VOC adsorbent of the polypropylene composite material, emission of VOCs can be greatly reduced, and the preparation method is simple and can easily realize batch production; and 2, compared with other molecular-sieve synthetic adsorbents, the calcined diatomite is greatly reduced in cost and good in adsorption effect.

Description

technical field [0001] The invention relates to a polypropylene composite material, specifically a low-VOC polypropylene composite material, and a preparation method of the composite material, belonging to the field of polymer modification and processing. Background technique [0002] VOC refers to volatile organic compounds, VOC is volatile organic compounds, which have a huge impact on human health. When the VOC in the room reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. decline and other serious consequences. As people pay more attention to indoor and in-vehicle air quality, my country has issued indoor and in-vehicle air quality standards, mainly including the content limits of benzene and aldehydes and ketones. [0003] Polypropylene has good processing performance, physical and chemical properties, extremely low density, and relatively low price, and is widely used in household appliances, automobiles and o...
