Abstract
The present invention relates to a long-acting antibacterial shaping plastic strip, which is characterized by comprising the following components, by weight, 90-95% of high density polyethylene, 1-3% of titanium dioxide powder, 0.3-1% of anhydrous white oil, and 5-10% of an inorganic nanometer antibacterial material. The long-acting antibacterial shaping plastic strip is used for producing packaging bag zippers, wherein a long-acting antibacterial effect is achieved, and hygienic quality of the packaging bag is improved.
Description
One, technical field
The present invention relates to a kind of plastic strip capable of being settled, relate in particular to a kind of plastic strip capable of being settled of long acting antibiotic.
Two, background technology
At present, but at the food bag sealing part slide fastener of opening and closing is housed, so that the storage of food, slide fastener is made with a kind of plastic strip of finalizing the design usually.Along with the raising of people's living standard, hygiene and health are also more and more paid attention to, for the material of food product pack, antibacterial is very important.Give antibacterial in the plastic strip that can finalize the design, not only people use and feel more relieved, and can improve the storage time of food.
Three, summary of the invention
For above-mentioned shortcoming, the object of the present invention is to provide a kind of plastic strip capable of being settled with long acting antibiotic function, it is used for making the packing bag slide fastener, can play good antibacterial effect, is conducive to depositing of food.
Technology contents of the present invention is, the plastic strip capable of being settled of long acting antibiotic is characterized in that it is comprised of the component of following weight percent: high density polyethylene(HDPE) 90～95%, titanium dioxide 1～3%, without water white oil 0.3～1%, inorganic nano antibacterial material 5～10%; Described high density polyethylene(HDPE) melt fat＜1; The fineness of described titanium dioxide is 3500～3800 orders; Described inorganic nano antibacterial material can be calcium oxide or phosphite; Described inorganic nano antibacterial material carrier band has silver ions or zine ion; And described inorganic nano antibacterial material is comprised of following components in weight percent: calcium phosphate 0.5～1.5%, aluminum oxide 2.0～3.0%, silver 2.5～3.5%, silica 1.0～2.0%, metal ion 0.5～1.5%, ceramics powder is 90～92%.
The beneficial effect that the present invention has is:
1, plastic strip capable of being settled of the present invention is used for the making of packing bag slide fastener, has good antibiotic effect, has improved the hygienic quality of packing bag;
2, the present device requirement is low, and cost is low, and is easy and simple to handle.
Four, embodiment
Embodiment 1,90kg is melted fat is that to be 3500 titanium dioxides and 0.5kg put into stirrer without water white oil stirs behind 10～15 powderies for subsequent use for 0.9 high density polyethylene(HDPE), 1kg fineness; In said mixture, add the nano calcium oxide 5kg that carrier band has silver ions, then enter injection moulding machine, be extruded into plastic strip through injection moulding machine, the thickness of the plastic strip of extruding is that 1.3mm, width are 35mm, and four sections Heating temperatures from the opening for feed of injection moulding machine to extrusion are respectively 170 ℃, 200 ℃, 180 ℃, 160 ℃; Put in the cooling trough through the plastic strip that injection moulding machine is extruded, the temperature of plastic strip is cooled to 75 ℃; Above-mentioned cooled plastic strip is stretched and roll extrusion through roller press respectively, and the thickness that stretches respectively is 1.0 and 0.8mm, and the rotating speed of twice roller press is respectively 450r/min and 1150r/min; Be cooled to 40 ℃ through cooling trough again; Cooled plastic strip is stretched and roll extrusion by roller press at last, the thickness that makes plastic strip is that 0.6mm, width are 3mm again, and the roller press rotating speed is 1050r/min; Can obtain product of the present invention.
