Abstract
The invention discloses a heat-insulating antibacterial composite plastic film which is characterized by being prepared from the following components in parts by weight: 50-80 parts of polyethylene, 15-20 parts of super-fine talcum powder, 100 parts of poval, 4-6 parts of organic montmorillonite, 2-3 parts of nano TiO2 powder, 2-3 parts of polyethylene wax, 1-3 parts of fatty acid, 1-3 parts of a coupling agent, 1.2-1.5 parts of an antioxidant 1010, 3-4 parts of hexadecyl trimethyl ammonium bromide, 0.2-0.5 part of a defoaming agent Byk028 and 0.8-1 part of a plasticizer. By use of the raw materials, the cost is lowered, the tensile strength and rigidity of a plastic product are enhanced, the transparency of the film is increased, and the heat retaining property of a mulching film is improved. The coupling agent can be used for enhancing the toughness of the plastic film, nano TiO2 plays an antibacterial and fresh-keeping effect and the shelf life is prolonged. According to the heat-insulating antibacterial composite plastic film, a microwave method is adopted, the preparation technology is simple and the reaction time is short.
Description
Technical field
The present invention relates to the proprietary material that synthetic resins produces the plastics such as plastics, packing film, mulch film, hollow piece, sheet material, tubing, be specifically related to the antibacterial composite plastic film of a kind of insulation.
Background technology
Along with the continuous progress of society, the usage quantity of macromolecular material in people's daily life is increasing, facility is brought to the life of people, improve the quality of the life of people, with the film that polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins are made, for packaging, and be used as coating layer.The commercially shared share of plastic wrapping and plastic packet product is increasing, particularly composite plastic soft packaging, the fields such as food, medicine, chemical industry are widely used in, but, produce large-scale and in use procedure, create a large amount of wastes, if these wastes do not abandon occurring in nature with adding any process, will be formed so-called " white pollution ", cause severe problem to society, become source of pollution human ecological environment being had to considerable damage effect.At present, plastics are mostly with polyethylene, polypropylene etc. for main raw material is made, and this kind plastics heat-insulating property is bad, light transmission is poor, and can not disintegrate, to environment, make to there is waste plastic in soil and destroy Soil structure.Nanometer Ti02 is photocatalyst, have antibacterial, sterilization, anti-ultraviolet function.How being made into insulation antibacterial plastic film, is the technical problem to be solved in the present invention.
Summary of the invention
The object of this invention is to provide the antibacterial composite plastic film of a kind of insulation, adding of super-fine talc improves plastics light transmission and heat-insulating property, and mechanical strength obviously strengthens.Nanometer Ti02 played have antibacterial, sterilization, anti-ultraviolet function.The product obtained has the physicalies such as tensile strength high and low temperature good water solubility.
The technical scheme that the present invention takes is:
The antibacterial composite plastic film of a kind of insulation, is characterized in that, be made up by weight ratio of following compositions:
Polyethylene 50-80 part, super-fine talc 15-20 part, polyvinyl alcohol 100 parts, organic montmorillonoid 4-6 part, nanometer Ti02 powder 2-3 part, polyethylene wax 2-3 part, lipid acid 1-3 part, coupling agent 1-3 part, antioxidant 1010 1.2-1.5 part, cetyl trimethylammonium bromide 3-4 part, defoamer Byk028 0.2-0.5 part, softening agent 0.8-1 part.
The above-mentioned polyvinyl alcohol polymerization degree is 2500-2600.
Above-mentioned coupling agent selects titanic acid ester or rare earth aluminic acid ester.
Above-mentioned softening agent is sorbyl alcohol or glycerine.
Be incubated a making method for antibacterial composite plastic film, it is characterized in that, comprise the steps:
(1) stir after the polyethylene of above-mentioned component, super-fine talc, polyvinyl alcohol, organic montmorillonoid, nanometer Ti02 powder and appropriate water being mixed in proportion, controlling radiation power is that 800w carries out wave radiation 5-8min;
(2) after question response completes and is cooled to room temperature, then add polyethylene wax, lipid acid, coupling agent, antioxidant 1010, cetyl trimethylammonium bromide, defoamer Byk028, softening agent employing high-speed mixer kneading, finally use injection moulding machine injection moulding.
Beneficial effect of the present invention is:
This product have employed the compositions such as a large amount of super-fine talcs, organo montmorillonite, reduce production cost, add the added value of inorganic powder, there is high heat preservation performance, synthetic resins can improve the physicals of plastics, improve tensile strength and the rigidity of plastics, increase the film clarity of film, improve the heat retaining property of mulch film.Coupling agent enhances the toughness reinforcing of plastics film, and nanometer Ti02 can anti-bacterial refreshing, extends the shelf life.The present invention adopts microwave method, and preparation technology is simple and the reaction times is short.
