Abstract
The invention discloses an automotive interior material. The automotive interior material comprises the following raw materials in parts by weight: 65-80 parts of polypropylene resin, 5-10 parts of thermoplastic polyurethane resin, 5-20 parts of saturated ethylene-octene copolymer, 3-5 parts of nano titanium dioxide, 10-20 parts of a toughening agent, 5-15 parts of a nucleating agent, 5-15 parts of a grafting compatilizer, 5-10 parts of a shock-resistance agent, 2-8 parts of zinc oxide, 0.1-2 parts of a lubricant, 0.1-2 parts of a plasticizing accelerator, 0.4-2 parts of a complex stabilizer and 0.3-2 parts of a coupling agent. The automotive interior material has a formula design to ensure that the automotive interior material is scratch-resistant, wear-resistant, dirt-resistant, odorless and ageing-resistant and has molding processability, thereby achieving the aims of high requirement and low price of people on automotive interiors.
Description
Technical field
The present invention relates to a kind of automotive interior material.
Background technology
Car interior material is to divide riding vehicle material by the spatial dimension of riding vehicle, only limits to design and utilization that riding vehicle inside gadget, equipment and epidermis thereof are decorated.Riding vehicle interior material relates to riding vehicle engineering materials and riding vehicle beauty treatment material two aspects, various in style, composition and complex process, and functional form is various.Press layer of structure and the function of riding vehicle inside gadget, can be divided into 3 classes such as facial ornament material, cushioning material and inside gadget framework material.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automotive interior material.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of automotive interior material, it is characterized in that, the raw material of this finishing material is filled a prescription as follows by weight: 65～80 parts of acrylic resins, 5～10 parts of TPU(Thermoplastic polyurethanes), 5～20 parts of unsaturated ethylene-octene copolymers, 3～5 parts of nano titanium oxides, 10～20 parts of toughner, 5～15 parts of nucleators, 5～15 parts of grafting compatilizers, 5～10 parts of anti-impact agent, 2～8 parts, zinc oxide, 0.1～2 part of lubricant, 0.1～2 part of plasticizing promotor, 0.4～2 part of compound stabilizer, 0.3～2 part of coupling agent.
Compared to prior art, the present invention has the following advantages:
Grafting up-Grading Design aspect: adopt maleic anhydride inoculated polypropylene and the composite toughening modifying of PU, not only improve impact resistance, and improved polypropylene abrasion-proof and tear strength, be mainly used in the shock-resistant and wear parts such as automobile, household electrical appliances, military products.
Strengthen design aspect: taking PP/PU as matrix, add alkali magnesium sulfate crystal whisker, 3000 order talcum powder, grafting compatilizer combination formula, through length-to-diameter ratio 48:1 response type twin-screw extrusion, more than the flexural strength of material reaches 30Mpa, resistance to the five fingers scraping reaches 1 grade.
Weather-proof technology: the goods of making for PP/PU pellet use for a long time or deposit in physical environment, be subject to the impacts such as light (particularly UV-light), heat, oxygen and moisture, appearance characteristics and physical and mechanical properties etc. can significantly decline, even lose practical value, developed the composite weather-proof system of the plurality of stable agent such as pentaerythritol phosphite for this reason, in PP/PU, add 0.4-0.6% compound stabilizer, through xenon lamp accelerated deterioration 1000 hours, not efflorescence, does not chap, and degradation is less than 40%.
Eliminate peculiar smell: evenly spread in PP/PU pellet by nano titanium oxide, decompose toxic and harmful, eliminate material peculiar smell, successfully test by CTI odor detection, reach more than 2 grades.
