Further, odor adsorption agent is one or more in activated carbon, porous silica, Woelm Alumina, porous molecular screen, activated zeolite.
Further, antioxidant is the compound that Hinered phenols antioxidant 1010 mixes with the mass ratio of 1:1 with phosphite ester kind antioxidant 168.
Further, color masterbatch be with polyethylene be carrier, carbon black concentration be the black masterbatch of 30%.
Further, lubricant is one or more in white mineral oil, Tissuemat E, calcium stearate, zinc stearate.
It is simple that the two of the purpose of the present invention are to provide a kind of production technology, and the preparation method of the automobile air duct material that efficiency is high comprises the following steps:
A, weigh each raw material according to above-mentioned percentage by weight, then by all raw material mix homogeneously；
B, the mixture obtained by step A put into double screw extruder and carry out pelletize；Wherein, setting the extruder temperature of double screw extruder as 175 DEG C～195 DEG C, main-machine screw rotating speed is 500 revs/min～600 revs/min, and feeding machine frequency is 20 hertz～25 hertz；
Finished product is obtained after C, cooling, dry, pelletizing.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
Automobile air duct material of the present invention is prepared from by high density polyethylene (HDPE) reworked material, toughener, weather resisting agent, odor adsorption agent, antioxidant, black masterbatch and lubricant compound, production cost is low, resulting materials abnormal smells from the patient is less, and resistance to impact, rigidity and weather resistance are excellent；Wherein, adopt the reworked material of high-density polyethylene bottle or the bucket reclaimed as the main base material preparing automobile exterior air inlet, abundance, with low cost, it is possible not only to reduce environmental pollution, more can realize recycling of resource；Adopt one or more in activated carbon, porous silica, Woelm Alumina, porous molecular screen, activated zeolite as odor adsorption agent, the multi-cellular structure that these materials have can effectively adsorb toxic and harmful molecule, thus eliminating the abnormal flavour of material itself；Adopt the cooperative effect that weather resisting agent and antioxidant are composite formed, it is possible to promote the weather resistance of material, with less addition, the weather-proof requirement of automobile air duct can be met.
