Abstract

The invention discloses a soft-touch modified material with low volatile organic compounds and low odor and a preparation method thereof and belongs to the technical field of high molecular materials.The soft-touch modified material is prepared from the following raw materials in parts by mass: 20 to 40 parts of high-melt-index co-polypropylene, 10 to 30 parts of glass fiber, 1 to 2 parts of an anti-scratching agent, 15 to 40 parts of high-crystallization homo-polypropylene, 20 to 30 parts of a thermoplastic elastomer, 3 to 5 parts of a compatilizer, 0.3 part of a main antioxidant, 0.2 part of an auxiliary antioxidant and 0.5 part of a lubricant. The soft-touch modified material disclosed by the invention can be used for reducing the odor concentration of the material and the content of the volatile organic compounds; a technology is simple and convenient to operate and the production benefits are high.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a soft-touch modified material with low volatile organic compounds and low odor, and also relates to a preparation method for the soft-touch modified material with low volatile organic compounds and low odor. Background technique [0002] Polypropylene is a non-toxic, tasteless, odorless, general-purpose plastic with excellent performance. It is used in various fields such as square pipe plugs, auto parts, mechanical instruments, etc. The disadvantages of low toughness and poor creep resistance are greatly restricted in application, and cannot be used as high-performance engineering plastics. Only after modification can engineering applications be realized. [0003] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical s...
