Abstract
The invention discloses an automotive trim material which is prepared from the following components in percentage by weight: 60-80% of polyolefin, 1-1.5% of an initiator, 1-10% of a polar small molecule-grafted material, 0.5-2% of a dispersant, 0.5-2% of an antioxidant, 0.5-2% of a stabilizing agent and 10-20% of inorganic filler. The automotive trim material disclosed by the invention has the beneficial effects that by adding the polar small molecule-grafted material, a base material is modified; by adding the inorganic filler, the requirement of toughness and restorability of deformation of the material is achieved; by adding the low-density inorganic filler, the low density is achieved; by adding the inorganic filler, the flexural modulus and the tensile strength of the material are improved; and by adding the inorganic filler, the high-load deformation temperature is achieved.
Description
Technical field
The present invention relates to a kind of automotive interior material, particularly a kind of body material is the material of polyolefine for automobile interior trim.
Background technology
In order to reach the requirement such as intensity, rigidity of use, the poor compatibility of automotive interior material and inorganic materials and polar material, material cost is high; Load deformation temperature is low, and using under summer high temperature has certain influence; Simultaneously resistance to acids and bases is weak, easily produces the phenomenon such as dissolving, swelling, ripple, fold, crackle, foaming.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of material for automobile interior trim, low density, height melts finger, and machine-shaping is convenient, modulus in flexure and tensile strength high, load deformation temperature is high, and resistance to acids and bases is strong.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
For a material for automobile interior trim, the described material for automobile interior trim comprises following component, polyolefine 60-80%, initiator 1-1.5%, polar micromolecules graft materials 1-10%, dispersion agent 0.5-2%, oxidation inhibitor 0.5-2%, tranquilizer 0.5-2%, mineral filler 10-20%.
The invention has the beneficial effects as follows: by adding polar micromolecules graft materials, realize the modification of body material; By adding mineral filler, realize the toughness of material and the requirement of deformation restorability; Low density is realized by adding low-density mineral filler; By adding the modulus in flexure and the tensile strength that improve material without tassement polaire; High loading texturing temperature is realized by adding mineral filler; Because polyolefine material and mineral filler are all chemical inert material, can not react with soda acid, realize resistance to acids and bases.Realize this material low density, height melts finger, and machine-shaping is convenient, modulus in flexure and tensile strength high, load deformation temperature is high, and resistance to acids and bases is strong.
