Abstract
The invention discloses a novel green environmental protection antibacterial door gasket rubber jacket material formula and a preparation method. The material formula comprises polyvinyl chloride resin, a citrate plasticizer, epoxidised soyabean oil, a lubricant, a filling agent, a toughening agent, a stabilizer and a toner. After the distribution according to the components, the above materials are uniformly mixed and undergo granulation. The rubber jacket is then formed by an extruding machine, inserted with a magnetic strip and welded to finish the manufacture of the door gasket. The invention solves the problem of unreasonable and non-environmentally friendly materials of present refrigerator seal materials. It is safe and environmentally friendly to adopt the citrate plasticizer as a main component of the formula.
Description
Technical field
The present invention relates to environment-friendly and green antimicrobial refrigerator gasket production technical field, specifically belong to a kind of material prescription and preparation method of novel environment friendly antibacterial green gasket gum cover
Background technology
At present, the softening agent of domestic and international most of door of refrigerator strip of paper used for sealing gum covers uses the softening agent of adjacent phenyl ester class as SE mostly, uses adjacent benzene class or other types softening agent certainly will cause the rising of carninomatosis rate.Adjacent benzene class softening agent has toxicity such as carinogenicity, is forbidden in products such as Food Contact class and household appliances, using by developed countries such as European Union, the U.S. at present; Because gasket working conditions and environment cause easily by pollutions such as dust, food, oils, and then mouldy living bacterium, so need in the component of gum cover, add antibacterial mildew inhibitor; Though the part softening agent is nontoxic, it is low or cost is too high or one or more shortcoming such as poor performance at low temperatures that it all has a plasticizing efficiency; Other softening agent are petroleum chemicals, consume resources such as coal, oil, and these resources are non-renewable.
Summary of the invention
The material prescription and the preparation method that the purpose of this invention is to provide a kind of novel environment friendly antibacterial green gasket gum cover; Solved that the current refrigerator strip of paper used for sealing is unreasonable with material, the problem of not environmental protection; Adopt the main recipe ingredient of citric acid ester plasticizer, safety and environmental protection as the gasket gum cover.
The technical scheme that the present invention adopts is following:
A kind of material prescription and preparation method of novel environment friendly antibacterial green gasket gum cover; Described this material prescription component comprises PVC RESINS, citrate plasticizer, epoxy soybean oil, lubricant, weighting agent, toughner, stablizer, toner, and its constituent mass part is:
100 parts of PVC RESINSs
Citrate plasticizer 38-55 part
Epoxy soybean oil: 22 parts
Lubricant 1-2 part
30 parts of weighting agents
10 parts of toughner
Stablizer 3-5 part
Toner is some
The preparation method: after above-mentioned material got togather by its set of dispense, uniform mixing used forcing machine moulding gum cover after granulation, penetrated the manufacturing that can accomplish door weather strip behind magnetic stripe and the welding fabrication.
Described citrate plasticizer is that ATBC, lubricant are that paraffin, weighting agent are 10～15 μ m for the water-ground limestone median size, and toughner is the powder nitrile rubber, and stablizer is calcium stearate, Zinic stearas and Triple Pressed Stearic Acid.
Compared with present technology, beneficial effect of the present invention is following:
The present invention adopts citric acid ester plasticizer, and its winter hardiness is good, and plasticizing efficiency is high; Move for a short time, do not have any toxicity, have natural antibacterial and mouldproof characteristic; Especially Hydrocerol A be cereal etc. all contain the glucide preparation; Be green renewable resources, be non-petroleum chemicals, do not consume fossil energies such as coal, oil.
