Abstract
The invention discloses a preparation method of an environment-friendly antibacterial plastic chopping board. The environment-friendly antibacterial plastic chopping board is prepared from 94 to 96wt% of polypropylene, and 4 to 6wt% of inorganic silver ion master batch. The preparation method comprises following steps: (1) mixing; (2) granulating; (3) hydraulic injection moulding; and (4) modifying, and trimming deflashing. The preparation method is simple; production cost is low; and the preparation method is convenient for popularization and application. Functional master batch is not used in the preparation method, so that the obtained environment-friendly antibacterial plastic chopping board is friendly to the environment, and possesses no toxicity or nocuity; inorganic silver ion master batch is taken as an antibacterial agent, and is capable of inhibiting growth of bacteria; antibacterial effect is obvious and long lasting; and antibacterial rate against escherichia coli and staphylococcus aureus can be more than 90%.
Description
Technical field
The present invention relates to a kind of making method of plastic chopping block, be specifically related to a kind of making method of environment-friendly type antibiotic plastic chopping block.
Background technology
Chopping board is conventional kitchen utensils in a kind of people's daily life, and traditional chopping board is to adopt wood materials to be made, as adopted trees directly to cut into chopping board shape.Along with the minimizing of the forest reserves, the restriction to timber felling, and the improving constantly of timber price, this class chopping board is fewer and feweri to be used, the plastic chopping block that the plastics of alternatively take form as raw material producer.
Plastic chopping block is prepared from by injection moulding with plastic master batch, if it is improper that plastic master batch is selected, can affect the environmental-protecting performance of plastic chopping block, even affect the healthy of human body, as Chinese patent < < antibacterial plastic sheet-like chopping board and manufacture method > > (publication number CN101407607A) thereof disclose with functional agglomerate, PP and antibacterial matrices are that raw material is prepared chopping board, the functional agglomerate of its use contains industrial latex composition, this not environmental protection of functional agglomerate, chopping board in use can affect the healthy of human body.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of making method of environment-friendly type antibiotic plastic chopping block, plastic chopping block safety and sanitation prepared by the method, have good fungistatic effect, and long service life.
To achieve these goals, the technical solution used in the present invention is as follows:
A making method for environment-friendly type antibiotic plastic chopping block, described plastic chopping block is made by the polypropylene of 94～96wt% and the inorganic silver ion master batch of 4～6wt%, and described making method comprises the steps;
(1) mix: by proportioning, take raw material, in high-speed mixer, mix;
(2) granulation: the material that step (1) is mixed is poured in screw extrusion press, is warmed to 200 ℃ by forcing machine, after screw rod stirs, dissolves, from die extrusion, makes masterbatch pellet;
(3) hydraulic pressure injection moulding: the masterbatch pellet that step (2) is made is put into the injection moulding machine that chopping board mould is housed, shapes and within 3-5 minute, obtains profiled sheeting;
(4) modification, deburring make environment-friendly type antibiotic plastic chopping block after processing.
On the basis of technique scheme, above-mentioned plastic chopping block is made by the polypropylene of 95wt% and the inorganic silver ion master batch of 5wt%.
Compared with prior art, beneficial effect of the present invention is:
Production technique of the present invention is simple, and low production cost is easy to promote the use of.The present invention fills a prescription rationally, does not use functional agglomerate, the complete environmental protection of chopping board making, nontoxic; The present invention is usingd inorganic silver ion master batch as antiseptic-germicide, and the plastic chopping block making can bacteria growing inhibiting, and antibacterial effect is obvious, and effect is lasting, to the antibiotic rate of intestinal bacteria and streptococcus aureus up to more than 90%; The plastic chopping block making can suppress the generation of peculiar smell, can significantly reduce the peculiar smell that microorganism is caused.
