The automobile air duct material is prepared from the following raw materials in parts by weight: 70-89 parts of high-density polyethylene reclaimed material, 12-25 parts of toughening agent, 0.3-1 part of weather-proof agent, 1-3 parts of odor adsorbent, 0.2-0.6 part of antioxidant, 1-3 parts of black matrix and 0.5-2 parts of lubricant; the preparation method comprises the following steps: weighing the raw materials according to the proportion, uniformly mixing all the raw materials, putting the mixture into a double-screw extruder for granulating, cooling, drying and granulating to obtain a finished product. The automobile air duct material prepared by the technical scheme has low production cost, and the obtained material has small smell and excellent impact resistance, rigidity and weather resistance.
CN108841064a discloses an automobile air duct material and a preparation method thereof. The air duct material comprises, by weight, 30-40 parts of polyethylene, 10-20 parts of modified epoxy resin, 2-6 parts of nano indium oxide, 4-10 parts of nano silicon micropowder, 2-6 parts of glass fiber, 3-9 parts of aluminum magnesium silicate powder, 2-8 parts of nano aluminum oxide, 1-4 parts of graphene, 2-8 parts of white carbon black, 4-12 parts of a toughening agent, 2-8 parts of a flame retardant and 1-3 parts of nano silver ion powder. The air duct material prepared by the technical scheme has excellent wear resistance, flame retardance and high temperature resistance, has good toughness, and prolongs the service life of an automobile air duct.
CN108676255a discloses a novel automobile air duct and a production process thereof. The main body material of the automobile air duct is a high-melt-strength polypropylene material, wherein the preparation method of the high-melt-strength polypropylene material comprises the following steps: uniformly premixing polypropylene, high-melting point crystalline polymer and compatilizer according to the formula, feeding the mixture into a double-screw extruder with the temperature of 160-300 ℃ and the length-diameter ratio of 32-52, and carrying out melt blending extrusion and granulation under the condition of controlling the rotating speed to 100-400 rpm; the formula of the high melt strength polypropylene material comprises 100 parts by weight of polypropylene, 5-60 parts by weight of high-melting point crystalline polymer and 2-50 parts by weight of compatilizer. The main material of the automobile air pipe provided by the technical scheme has no environmental pollution, is nontoxic and odorless, can be recycled, does not influence the performance, and the prepared automobile air pipe has the characteristics of light weight, strong stability, high deformation recovery rate, oil resistance, acid resistance, alkali resistance and various chemical solvents resistance, can keep the main material unchanged for a long time in a cabin environment, is insulating and heat-resistant, and can effectively block the high temperature in the cabin.
At present, the preparation of an automobile air duct is commonly used as a method for bonding foam on the outer layer of a blow-molded HDPE (high-density polyethylene) air duct and a method for performing plastic suction molding on XPE material (chemical cross-linked polyethylene foam material). As is well known, in the process of circulating air flow in the air duct, dust and moisture are attached to the air duct in the vehicle, so that the breeding of microorganism bacteria is facilitated, and when air circulates again, the air can take away the bacteria in the air duct and convey the bacteria into the vehicle, so that the health of passengers is influenced. The blow molding HDPE air duct is unfavorable for the growth and breeding of microorganisms due to the smooth surface of the plastic, and has little influence on the air quality in the automobile, so that the problem that the damage to the human health is caused due to the breeding of microorganisms in the air duct is less considered when the HDPE is used for preparing the air duct. But XPE wind channel material surface has a lot of microporous structures, has light-weighted and condensation effectual advantage outside, and dust, steam, the harmful substance in the air when passing in the tuber pipe, these micropores do benefit to adsorb these harmful substance to breeds in the wind channel.
Therefore, how to meet the light weight requirement can also ensure that microorganisms can not be gathered in the XPE air duct, harmful substances generated by the air duct can not be taken away by air circulated in the air duct, bad driving experience is avoided for passengers, and the XPE air duct is a technical problem to be solved in the prior art.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide an XPE air duct for an automobile and a preparation method thereof. According to the invention, through designing the XPE air duct preparation raw materials for the automobile, the XPE air duct which is light and has good antibacterial and mildew-inhibiting performances is further prepared by adopting a specific antibacterial agent.
To achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the invention provides an XPE air duct for an automobile, which is characterized in that the XPE air duct comprises the following raw materials in parts by weight:
50 to 100 parts of polyethylene, 10 to 35 parts of foaming agent, 8 to 20 parts of modified zinc oxide, 1 to 10 parts of calcium stearate, 2 to 8 parts of cross-linking agent, 0.5 to 1.5 parts of coupling agent and 0.3 to 1.6 parts of antibacterial agent;
the antimicrobial agent comprises a combination of a nano silver antimicrobial agent and a nano zinc oxide antimicrobial agent.
In the prior art, when the XPE material is used for preparing the air duct for the automobile, as the surface of the XPE air duct material has a plurality of micropore structures, the XPE air duct material has the advantages of light weight and good condensation effect, but when dust, water vapor and harmful substances in the air pass through the air duct, the micropores are favorable for adsorbing the harmful substances and are multiplied in the air duct, bacteria are generated, and the air quality in the automobile is affected. The XPE material which is light and has better antibacterial and mildew-inhibiting properties is prepared by using the specific antibacterial agent, and is suitable for preparing the automobile air pipe.
