Embodiment 1

[0016] In the embodiment of the present invention, an odorless automotive interior trim material is composed of the following raw materials in parts by weight: 45 parts of polypropylene, 11 parts of polytetrahydrofuran ether glycol, 3 parts of N-alkyl-2-pyrrolidone, 5 parts of nano silver ion, 15 parts of cyanoethyl cellulose, and 1 part of yttrium oxide.

[0017] Mix polytetrahydrofuran ether glycol with 3.8 times its mass of 65% ethanol to prepare polytetrahydrofuran ether glycol solution; mix N-alkyl-2-pyrrolidone with 1.6 times its mass of isopropanol to prepare N-alkyl -2-pyrrolidone solution. The mixture A is obtained by mixing and grinding nano-silver ions and yttrium oxide, and passing through a 120-mesh sieve. Mix and grind polypropylene and cyanoethyl cellulose, pass through a 150-mesh sieve, put it into a polytetrafluoroethylene reaction kettle, then add polytetrahydrofuran ether glycol solution, seal it, and heat and stir it at 114°C for 35 minutes. Then add mixt...

Abstract

The invention discloses an odorless automotive upholstery material and a preparation method thereof. The upholstery material is prepared from the following raw materials in parts by weight: 45 to 55 parts of polypropylene, 11 to 19 parts of polytetrahydrofuran ether glycol, 3 to 7 parts of N-alkyl-2-pyrrolidone, 5 to 12 parts of nano silver ion, 15 to 23 parts of cyanoethyl cellulose and 1 to 5 parts of yttrium oxide. The nano silver ion and the yttrium oxide are mixed and ground, so as to make a mixture A; the polypropylene and the cyanoethyl cellulose are mixed and ground, an obtained first mixture is put into a polytetrafluoroethylene reaction kettle, a polytetrahydrofuran ether glycol solution is added into the reaction kettle, an obtained second mixture is sealed, heated and agitated, the mixture A and an N-alkyl-2-pyrrolidone solution are added into the reaction kettle, and an obtained third mixture is sealed, pressurized, heated, agitated, extruded and granulated, so that the odorless automotive upholstery material is obtained. The odorless automotive upholstery material and the preparation method have the advantages that a process is simple; a product has the characteristics of low odor, light weight, bright and clean surface, high temperature and low temperature resistance, impact resistance, wrinkle resistance, high rigidity and toughness, good sound-absorbing and heat-insulating performance, non-deformation, non-discoloring and the like; the odorless automotive upholstery material can be widely applied to the field of automotive upholstery.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an odorless auto interior trim material and a preparation method thereof. Background technique [0002] Polypropylene (PP) material has been widely used in various assembly systems of automobiles due to its good comprehensive performance. Most of the automotive exterior and interior parts are injection molded using polypropylene composite materials. Automotive interior parts such as dashboards, pillars, glove boxes, door panels, etc., exterior parts such as bumpers, anti-scratch strips, spoilers, etc. In addition to good mechanical properties, processing properties, weather resistance and scratch resistance, automotive interior materials must also have good low volatility, and odor requirements are one of the evaluations of volatile substances. In order to limit the odor of interior trim materials, the world's major automobile manufacturers have embarked on research work in ...
