Abstract

The invention discloses a low-odor polypropylene material for automobile interior decoration and a preparation method and application thereof. The low-odor polypropylene material for automobile interior decoration is prepared from the following components in percentage by mass: 40 to 70 percent of block copolymer polypropylene, 20 to 30 percent of halloysite nanotube masterbatch, 5 to 20 percent of an ethylene octene copolymer, 1 to 10 percent of deodorant masterbatch, 0 to 0.5 percent of a nucleating agent, 0 to 0.5 percent of an antioxidant and 0 to 0.5 percent of a lubricant. According to the low-odor polypropylene material for automobile interior decoration, block copolymerized polypropylene is used as a resin base material, and is modified by adding the halloysite nanotube masterbatchand the deodorant masterbatch, thereby improving the scratch resistance of the polypropylene material and reducing the volatility and odor. The low-odor polypropylene produced by the invention can bewidely used in the automobile field.

Description

technical field [0001] The invention belongs to the technical field of modification of polymer composite materials, and in particular relates to a low-odor polypropylene material for automobile interior decoration and its preparation method and application. Background technique [0002] As people's requirements for the living environment are getting higher and higher, automobile manufacturers have also put forward new and higher requirements for the content control of volatile low molecular compounds, good touch and scratch resistance of automotive interior materials. . Research has found that textiles, leather, adhesives, sealants, etc. used in the car have a high volatilization of VOCs, which is directly related to the bonding material phenolic resin used in the manufacturing process. Therefore, the selection of materials that do not contain or contain low amounts of phenolic resin is an important way to reduce the VOC content in the car. The modified polypropylene (PP) ...
