Abstract

The invention relates to a special antimicrobial mould-proof low-odor regenerative polypropylene modified material for an automobile instrument desk. The special antimicrobial mould-proof low-odor regenerative polypropylene modified material is characterized by comprising the following components in parts by weight: 91.5 to 98.5 parts of base material, 0.5 to 3 parts of composite odor eliminating agent, 0.5 to 3 parts of nano composite antimicrobial agent, 0.1 to 0.5 part of antioxidant, 0.1 to 0.5 part of ultraviolet absorption agent, 0.1 to 0.5 part of lubricating agent, 0.1 to 0.5 part of coupling agent and 0.1 to 0.5 part of white oil. The base material comprises the following components in parts by weight: 10 to 70 parts of regenerative polypropylene material, 0 to 30 parts of polypropylene fresh material, 3 to 20 parts of flexibilizer and 0 to 40 parts of filler. The invention also provides a preparation method of the special antimicrobial mould-proof low-odor regenerative polypropylene modified material. The special antimicrobial mould-proof low-odor regenerative polypropylene modified material for the automobile instrument desk is low in odor, good in antimicrobial durability and safe to use; the utilization rate of the regenerative material is greatly increased, a good circulating system is formed, and the environment can be improved. The preparation method is simple and easy and high in practical value.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to automotive materials, in particular to an antibacterial, mold-proof, low-odor regenerated polypropylene modified automotive instrument panel special material and a preparation method thereof. Background technique [0002] Polypropylene is a material with good processing properties. It has good oil resistance, chemical resistance, light weight, and low price. It is currently being widely used, and it is also the fastest growing thermoplastic. [0003] Polypropylene is widely used in household appliances, automobiles, electronics, and daily necessities packaging. In recent years, our country has entered a period of scrapping a large number of household appliances, automobiles, electronic products, daily necessities, etc. The recycling and secondary utilization technology of polypropylene materials has become a sustainable development method. The recycled polypropylene is due to the circul...
