Abstract
The invention discloses a low-smell plastic used in automobiles, which comprises the following components in percentage by weight: 69%-89% of general-purpose plastic, 10%-30% of modifiers, 0.1%-0.5% of antioxidants, 0.1%-0.5% of lubricating agents and 0.3%-0.6% of adsorbents, and the proportion sum of the components is 100%; the adsorbents are mixed adsorbents formed by compounding a BX molecular sieve with a chemical adsorbent ZEOFLAIR in the weight ratio of 1:1-1:2. When reserving the original properties of the general-purpose plastic, the low-smell plastic has low smell, the smell level reaches 3 level and meets the environmental-protection requirement for manufacturing internal parts of the automobiles, such as parts around automobile engines, trimmings, instrument boards and the like. Besides, the low-smell plastic has simple preparation process and lower cost and meets the requirement of industrial production.
Description
Technical field
The present invention relates to a kind of low smell plastics that are used in the automobile, specifically, relate to a kind of plastic prod that is used for the automobile inner part that parts around the automobile inner ornament, dashboard, engine etc. have higher requirements to smell, belong to the processing modified technical field of general-purpose plastics.
Background technology
General-purpose plastics on our ordinary meaning is meant that output is big, purposes is wide, good moldability, low-cost plastics.General-purpose plastics has five big kind, i.e. polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS.They have light weight, chemical property stable, can not corrosion, good shock-resistance, wear resistant, good insulation, lower thermal conductivity, formability, good tint permanence and lower advantages such as tooling cost preferably preferably, thereby be widely used in automotive industry.
, general-purpose plastics becomes the material of present usage quantity maximum though having the performance of a lot of brilliances; but the plastics of making automobile inner parts such as parts around the motor car engine, interior jewelry, dashboard at present are ABS and PP plastics; certain volatility is arranged; in car, produce a kind of niff; thereby influenced Air quality in the car, user's health and environment protection caused certain infringement.Along with people are more and more higher to environment protection and physically and mentally healthy requirement, how to remove and reduce to be used for the interior plastics peculiar smell of automobile, will be the technical barrier that the general-purpose plastics industry presses for solution, significant to the development that impels automobile industry.The technical scheme that though the inventor discloses in Chinese patent literature CN101314658A a kind of " general-purpose plastics of low smell and preparation method thereof ", reduced the smell of general-purpose plastics to a certain extent, make the oder levels of the general-purpose plastics after the modification reach 3 grades, but still have a peculiar smell, also have a certain distance apart from people's health requirements.
Summary of the invention
The objective of the invention is to aim to provide a kind of low smell plastics that are used in the automobile, to overcome the above-mentioned defective of existing in prior technology and the health requirements and the market requirement that satisfy people.
For achieving the above object, the technical solution used in the present invention is as follows:
The low smell plastics that are used in the automobile of the present invention, the weight percent that it is formed and each is formed is as follows:
General-purpose plastics 69%～89%
Properties-correcting agent 10%～30%
Oxidation inhibitor 0.1%～0.5%
Lubricant 0.1%～0.5%
Sorbent material 0.3%～0.6%
Above-mentioned each proportioning sum of forming is 100%; Described sorbent material is that BX molecular sieve and chemosorbent ZEOFLAIR were by 1: 1～1: the 2 composite mixed adsorbent that forms of weight ratio.
Described general-purpose plastics optimization polypropylene (PP) plastics or ABS plastic.
Described properties-correcting agent is selected from any one or more than one the composition in heat-resistant agent, fire retardant and the static inhibitor.
The preferred N-phenylmaleimide of described heat-resistant agent; The preferred TDE of described fire retardant (DBPE); The preferred polyoxyethylene glycol of described static inhibitor is polymeric amide (PEG-PA).
The preferred Hinered phenols antioxidant 1010 of described oxidation inhibitor and phosphite ester kind antioxidant 168 by 1: 1～1: 3 weight ratio composite form mix oxidation inhibitor.
The preferred ultra-high molecular weight polysiloxane of described lubricant.
The preparation technology who is used for the low smell plastics in the automobile of the present invention is as follows:
A) each component is added in the high mixer by proportioning, at room temperature mix;
B) place twin screw extruder to carry out extruding pelletization the above-mentioned material that mixes, screw speed is 180～600 rev/mins, and extrusion temperature is 160～230 ℃.
Because there is a large amount of holes in the BX molecular sieve, has very large specific surface area, can carry out selective adsorption to molecule according to the size in crystals hole, promptly adsorb a certain size molecule and repel the molecule of material greatly, it can well mix with general-purpose plastics, in plastic substrate, can disperse relatively evenly, and durable, the high temperature of anti-processing; Chemosorbent ZEOFLAIR is an organic inorganic powder a kind of white, multi-cellular structure, close, it has high adsorptive power to smell and organism, go even ZEOFLAIR covered in the polymer nature, can not change its strong adsorptive power at all yet, ZEOFLAIR can directly adsorb small molecules in polymkeric substance, and they are firmly adhered in the crystalline structure, can thoroughly eliminate the peculiar smell of plastics.Add man-hour when extruding, the BX molecular sieve can well adsorb the small molecules volatile matter, and these small molecules volatile matters are adsorbed on the inside, and what make that these volatile matters can be stable is retained in the resin and can not disperses out, thereby reduces the smell of plastics; Chemosorbent ZEOFLAIR can well react with the small molecules volatile matter, and the stable compound that combines generation with these volatile matters and do not have peculiar smell is retained in the resin and does not disperse out, thereby plays the effect of removal plastics peculiar smell.Therefore, the present invention is composite to together with both, makes between the two to act synergistically, and removes the small molecules volatile matter from chemical and physics two aspects, thereby has effectively reduced the smell of general-purpose plastics.
Compared with prior art, product of the present invention has low smell when keeping the general-purpose plastics primary characteristic, and oder levels reaches 3 grades, meets to make the motor car engine environmental requirement of automobile inner parts such as parts, interior jewelry, dashboard on every side.In addition, the preparation technology of product of the present invention is simple, cost is lower, meets the suitability for industrialized production requirement.
