Abstract
The present invention discloses a method for making antibacterial drinking water urn. Said method includes the following steps: firstly, making high-concentrated antibacterial PET mother granules: uniformly mixing PET, nano-grade inorganic antibacterial agent and adjuvant in high-speed mixing machine; then placing the above-mentioned mixture into twin screw extruder machine, in the temperature range of 250-280deg.C melting and making high-concentrated antibacterial PET mother granules; then mixing the obtained high-concentrated antibacterial PET mother granules and PET raw material according to a certain ratio, drying for 4hr. at 150deg.C in air blast drying machine, adding the above-mentioned material into injection-moulding machine and forming to obtain drinking water urn bottle blank, then placing said drinking water urn bottle blank into bottle-blowing machine to make blowing so as to obtain the invented antibacterial drinking water urn.
Description
Affiliated technical field:
The present invention relates to a kind of scuttlebutt, particularly have the manufacture method of the scuttlebutt of antibacterial functions.
Background technology:
In recent years, along with improving constantly of living standards of the people, water dispenser is greatly universal, after water dispenser uses a period of time, unavoidable airborne bacterium and user with bacterium sneak in the bucket, the water that water in the scuttlebutt flows out by water dispenser, its bacterium severe overweight, the secondary pollution problem of formation water dispenser.At present, scuttlebutt is generally common plastic products, does not have antibacterial functions.
Summary of the invention:
The present invention is directed to the shortcoming of prior art, a kind of nano-antibacterial scuttlebutt is provided, can suppress the transparency that common bacteria keeps material simultaneously effectively.
The manufacture method of antibacterial watering bucket of the present invention is at first to make highly enriched antibacterial PET master batch: PET is evenly mixed in high-speed mixer with nanometer grade inorganic antibacterial agent and auxiliary agent; Be put into then in the double screw extruder, fusion manufactures highly enriched antibacterial PET master batch in Celsius temperature 250 degree and 280 degree scopes; Secondly will the above-mentioned highly enriched antibacterial PET master batch of making mixes according to 5 percent ratio of percentage by weight with the PET raw material, in blast drier Celsius 150 spend under drying after 4 hours, be shaped to scuttlebutt bottle embryo in the adding injection machine; Again scuttlebutt bottle embryo is put into bottle blowing machine and be blow molded into scuttlebutt.
Owing to adopt nanometer grade inorganic antibacterial agent and correct processing technology in the scuttlebutt, can suppress the transparency and original color and luster that common bacteria has kept the conventional polyester scuttlebutt simultaneously effectively.This antibacterial watering bucket meets " the no gas beverage bottle of polyester (PET) " (QB2460-99) about sealing, vertically plant physical property requirements such as pressure, drop performance, and " food containers and packaging material with PETG moulding product sanitary standard " requirement (GB13113-91).And detect according to QB/T2591-2003 " antibiotic plastic anti-microbial property test method and antibacterial effect " and Japanese national industrial standard JIS Z 2801-2000 " antibiotic fabricated product-antibiotic property test method and antibacterial effect ", this antibacterial watering bucket for the antibiotic rate of Escherichia coli and staphylococcus aureus greater than 90%.
The specific embodiment:
The present invention has added the nanometer grade inorganic antibacterial agent in material PETG (PET).Inorganic nano antiseptic is the method that adopts physical absorption and ion-exchange, will have the Ag of antibacterial action
+, cu
2+, zn
2+Plasma and compound thereof are adsorbed on such as in the loose porous carrier material such as zeolite, silica gel, bentonite and obtain.It has high temperature resistant, be difficult for advantages such as decomposition, safety and sanitation, function be lasting.
The most frequently used a kind of method of making inorganic nano antiseptic is to make carrier with the hydrosilicate of alkali metal or alkaline-earth metal at present.It is that a kind of 4 bodies of silicon, aluminium, oxygen that connected by the oxo bridge key are the unlimited structure arranged of skeleton shape at 3 dimension spaces.In 4 bodies.1 negative valency that aluminium connected carries out balance by tradable cation.Oxo bridge becomes many passages to 4 sports associations, and making has the Ag of antibacterial action
+, cu
2+, zn
2+Plasma can exchange easily with tradable cation in the hydrosilicate.When ion-exchange reaches balance, with mixed liquor filter, fully washing, dry, refining.
Manufacture process of the present invention:
1. at first make highly enriched antibacterial PET master batch: get 100 kilograms PET, in high-speed mixer, evenly mix according to the ratio and the nanometer grade inorganic antibacterial agent of form 1 (the FUMAT T200-6 that provides by the Shanghai WeiLai New Materials Science Co., Ltd of selling on the market) and auxiliary agent zinc stearate, ethylene bis stearamide, polypropylene wax, isopropyl three (dioctylphosphato) metatitanic acid fat; Be put in the double screw extruder, fusion manufactures highly enriched antibacterial PET master batch in Celsius temperature 250 degree and 280 degree scopes.

2. make nano-antibacterial scuttlebutt finished product:
The highly enriched antibacterial PET master batch of above-mentioned 5 kilograms made from after 100 kilograms PET raw material mixes, in blast drier under 150 degree Celsius after dry 4 hours, is added in the injection machine and is shaped to scuttlebutt bottle embryo; Again scuttlebutt bottle embryo is put into bottle blowing machine and be blow molded into scuttlebutt.In antibacterial watering bucket, contain nanometer grade inorganic antibacterial agent 0.5～1%.
Claims (2)
1. the manufacture method of an antibacterial watering bucket is characterized in that:
At first make highly enriched antibacterial PET master batch: PET is evenly mixed in high-speed mixer with nanometer grade inorganic antibacterial agent and auxiliary agent; Be put into then in the double screw extruder, fusion manufactures highly enriched antibacterial PET master batch in Celsius temperature 250 degree and 280 degree scopes;
Secondly will the above-mentioned highly enriched antibacterial PET master batch of making mixes according to 5 percent ratio of percentage by weight with the PET raw material, in blast drier Celsius 150 spend under drying after 4 hours, be shaped to scuttlebutt bottle embryo in the adding injection machine; Again scuttlebutt bottle embryo is put into bottle blowing machine and be blow molded into scuttlebutt.
