Abstract
The invention relates to a preparation method for a plastic shell used for an electronic product, belonging to the field of plastic products. The preparation method for the plastic shell used for the electronic product provided by the invention comprises the following process steps: mixing antibacterial composite powder, polyethylene glycol and high density polyethylene according to a weight ratio of 2-15: 10-30: 100, wherein the antibacterial composite powder is silver oxide/titanium oxide/scandium oxide composite powder; mixing the obtained mixture with polymethylmethacrylate according to a weight ratio of 1-5: 100; and then carrying out compounding, crosslinking and molding. The shell used for the electronic product prepared by using the method of the invention has the advantages of good antimicrobial property and excellent insulating property; meanwhile, the method is simple and is fast in molding.
Description
Technical field
The present invention relates to a kind of preparation method of use for electronic products plastic casing, belong to field of plastic products.
Background technology
Along with the development of science and technology, the life of people is more and more convenient, especially in office, along with various office appliance easily occurs, as computer, fax, phone, printer, staff can process a large amount of things in office, and the time of these office appliances of worker exposure is also more and more longer thus, and the security of electronic product is also more and more subject to people's attention.Plastics are more and more subject to people's attention for sheating material as substantially all electronic products, and due to the shell of people's Long contact time electronic product, and the cleaning frequency of most of electronic product is lower, very easily breed bacteria and be infected with dirt.
Summary of the invention
The object of this invention is to provide a kind of preparation method of use for electronic products plastic casing, the use for electronic products housing utilizing the method to prepare has that anti-microbial property is good and insulating property are good, and the method is simple, soon shaping.
A preparation method for use for electronic products plastic casing, comprises following processing step:
I. be that 2 ~ 15:10 ~ 30:100 is placed in mixing roll and carries out mixing 5 ~ 20min by weight by antibacterial composite granule, polyoxyethylene glycol, high density polyethylene(HDPE), wherein, described antibacterial composite granule is silver suboxide/titanium oxide/Scium trioxide composite granule;
II. be that 1 ~ 5:100 mixes with poly-methyl methacrylate vinegar by step I gained mixture by antibacterial composite granule and the weight ratio of poly-methyl methacrylate vinegar, and carry out mixing 10 ~ 30min in mixing roll;
III. after adding linking agent in Step II gained mixture, shaping.
The preferred described step I of preparation method of use for electronic products plastic casing of the present invention: be that 8 ~ 15:15 ~ 25:100 is placed in mixing roll and carries out mixing 5 ~ 20min by weight by antibacterial composite granule, polyoxyethylene glycol, high density polyethylene(HDPE).
The preferred described step I of preparation method of use for electronic products plastic casing of the present invention: be that 8 ~ 12:18 ~ 24:100 is placed in mixing roll and carries out mixing 5 ~ 20min by weight by antibacterial composite granule, polyoxyethylene glycol, high density polyethylene(HDPE).
Silver suboxide in molar ratio in the preferred described silver suboxide/titanium oxide/Scium trioxide composite granule of preparation method of use for electronic products plastic casing of the present invention: titanium oxide: Scium trioxide is 10 ~ 30:25 ~ 40:1 ~ 10.
Silver suboxide in molar ratio in the preferred described silver suboxide/titanium oxide/Scium trioxide composite granule of preparation method of use for electronic products plastic casing of the present invention: titanium oxide: Scium trioxide is 15 ~ 25:30 ~ 40:1 ~ 5.
The molecular weight of the preferred described high density polyethylene(HDPE) of preparation method of use for electronic products plastic casing of the present invention is 500000 ~ 2000000.
The preferred described Step II of preparation method of use for electronic products plastic casing of the present invention: be that 2 ~ 3.5:100 mixes with poly-methyl methacrylate vinegar by antibacterial composite granule and the weight ratio of poly-methyl methacrylate vinegar by step I gained mixture, and mixing 10 ~ 30min is carried out in mixing roll.
The invention has the beneficial effects as follows: the preparation method of use for electronic products plastic casing of the present invention, comprise following processing step: it is mixing by antibacterial composite granule, polyoxyethylene glycol, high density polyethylene(HDPE) to be that 2 ~ 15:10 ~ 30:100 carries out by weight, wherein, described antibacterial composite granule is silver suboxide/titanium oxide/Scium trioxide composite granule; Be that 1 ~ 5:100 mixes with poly-methyl methacrylate vinegar by gained mixture by antibacterial composite granule and the weight ratio of poly-methyl methacrylate vinegar, and mixing, crosslinked, shaping.The use for electronic products housing utilizing the method to prepare has that anti-microbial property is good and insulating property are good, and the method is simple, soon shaping.
