experiment example 1

[0032] The preparation method of the deodorant 2: prepare 10% ethanol solution with 2,4-dinitrophenylhydrazine and ethylenediamine tetramethylene phosphoric acid according to the mass ratio of 1:1.5, measure 1L of the solution, Add 450g of 13X-type zeolite molecular sieve, stir for 4 hours and then filter with suction. During the process of suction, rinse with absolute ethanol for 3 times, dry, grind and sieve to obtain the deodorant 2 loaded with reactive porous substances, which is denoted as CWJ-1 .

experiment example 2

[0034] The preparation method of the deodorant 2: make methylenetriamine pentamethylene phosphoric acid into 8% ethanol solution, measure 1L of the solution, add 300g of 13X type zeolite molecular sieve, stir for 5h, then suction filter, During the filtration process, rinse with absolute ethanol for 5 times, dry, grind and sieve to obtain the deodorant 2 loaded with reactive porous substances, which is designated as CWJ-2.

experiment example 3

[0036] The preparation method of the deodorant 2: make ethylenediamine tetraacetate into 3% ethanol solution, measure 1L of the solution, add 300g of 13X zeolite molecular sieve, stir for 3h and then suction filter. Rinse twice with absolute ethanol, dry, grind and sieve to obtain the deodorant 2 loaded with reactive porous substances, which is designated as CWJ-3.

Abstract

The invention relates to a low-odor scratch-resistant polypropylene composite material, which is prepared from the following raw materials by mass: 44.6-96.6% of polypropylene, 0-40% of talcum powder,0.4-4% of an antioxidant, 1-5% of a deodorant 1, 1-5% of a deodorant 2 and 1-5% of a scratch-resistant aid, wherein the deodorant 1 is one or a plurality of materials selected from water, hexamethyldisilane, hexamethyldisiloxane, triethylsilanol and octamethyltrisiloxane, and the deodorant 2 is mesoporous silica or a 13X type zeolite molecular sieve loading at least one selected from ethylenediamine tetraacetic acid salt, methylene triamine pentamethylene phosphoric acid, ethylenediamine tetramethylene phosphoric acid and 2,4-dinitrophenylhydrazine. According to the invention, the product hasexcellent low-odor and excellent scratch resistance, reduces the antagonism among odor, diffusivity and scratch resistance, and finally realizes the balance of odor, diffusivity and scratch resistance of the product.

Description

technical field [0001] The invention belongs to the field of polypropylene composite materials, in particular to a low-odor and scratch-resistant polypropylene composite material and a preparation method thereof. Background technique [0002] Under the trend of "replacing steel with plastic", polypropylene can fully meet the material performance requirements of automotive interior parts through toughening, strengthening and other modifications. Nowadays, modified polypropylene materials are widely used in automotive interiors, mainly used in instrument panels, door guards, sub-dashboards, pillar guards and other components. As the main material used in automotive interior parts, polypropylene material has obvious advantages in terms of processability and price, but polypropylene composite materials also have a common problem as polymer materials, that is, the material emits small organic molecules during use. Substances seriously affect the riding environment in the car; an...
