Description
Technical field
The present invention relates to one water pipe material technical field, particularly relate to a kind of antimicrobial PE tube。
Background technology
Polyvinyl resin is the aggregated prepared a kind of thermoplastic resin of ethylene, extensively it is applied to plastic industry, during especially as tubing aspect, there is good performance, feedwater polyethylene tube (PE pipe) is traditional iron and steel tubing simultaneously, the regeneration product of polrvinyl chloride drinking-water pipe, owing to its intensity is high, high temperature resistant, anticorrosive, nontoxic, the feature such as wear-resisting, it is widely used in plumbing and manufactures field, but the anti-microbial property of the feedwater PE pipe having currently on the market is not fine, can pollute when water transmits, therefore, our company adopts a kind of nano-class antibacterial agent to join in PE inner tube layer, thus solving the desirable problem of antibacterial effect on existing market。
Summary of the invention
The technical problem to be solved is in that: providing a kind of antimicrobial PE tube, described antimicrobial PE tube can solve the problem that existing antibacterial pipe antibacterial effect is undesirable。
For solving the problems referred to above, the technical scheme is that a kind of antimicrobial PE tube, described antimicrobial PE tube has double-decker, including 100% polyvinyl resin form outer layer and 95% polyvinyl resin and 5% antibacterial composition internal layer, internal layer and outer layer account for the percentage by weight of tubing gross weight and are:
Internal layer 8%～12%
Outer layer 88%～92%。
Further, described nano antibacterial agent is made up of the raw material of following weight proportioning:
1～2 part of 5～10 parts of nanometer silver powder of silicon dioxide
1～3 part of butyl titanate 1～3 part of glacial acetic acid of 3～6 parts of propanol
Its preparation process is:
(1) silicon dioxide is sent in reactor, add water and stir, be warmed up to 150 DEG C；
(2) being sufficiently mixed with silicon dioxde solution in nanometer silver powder addition reactor, react subsequently, after a period of time, chilling temperature, to 50 degrees Celsius, obtains mixed material A；
(3) by ratio mixing certain to butyl titanate, propanol and glacial acetic acid ammonium, put into stirring 1h on thermostatic electromagnetic agitator, obtain mixed material B；
(4) mixed material B is instilled in mixed material A, after stirring, it is dried process；
(5) subsequently mixed material is dried, milled processed, obtain finished product anti-bacterial powders。
Further, a period of time of described step (2) is 2h。
Further, the butyl titanate of described step (3), propanol and glacial acetic acid mix in 2:1:1 ratio。
Further, described antimicrobial PE tube preparation process is, first polyvinyl resin and antibacterial is granulated through blender high stirring at low speed；By prepared particle and the polyvinyl resin coextrusion mold being used as outer layer raw material；Subsequently it is cut, finished product can be obtained。
Compared with prior art, polyvinyl resin and antibacterial are first granulated by the present invention through blender high stirring at low speed, again by prepared particle and the polyvinyl resin coextrusion mold being used as outer layer raw material, adopting the technology such as high stirring at low speed, two layers of co-extrusion to enhance its corrosion resistance, be prone to the performance such as hot-melt adhesive paste, high intensity, with the addition of antibacterial in operation adds the antibacterial ability of PE pipe simultaneously。Thus meet people life in feedwater PE pipe the antibacterial requirement of height, solve the problem that existing antibacterial pipe antibacterial effect is undesirable。
