Abstract
The invention relates to an antimicrobial PE (poly ethylene) pipe. The antimicrobial PE pipe has a double-layer structure and comprises an outer layer and an inner layer, the outer layer is made of 100% of poly ethylene resin, and the inner layer is composed of 95% poly ethylene resin and 5% of nanometer antimicrobial agent. The weight percentages of the inner layer and the outer layer of the total weight of the pipe are 8-12% and 88-92% respectively. The poly ethylene resin and the antimicrobial agent are mixed and pelleted at high and low speed by a mixer, obtained particles and the poly ethylene resin for the outer layer are coextruded to mold, and such performances as corrosion resistance, hot-melting connection, high intensity and the like are improved by high- and low-mixing and two-layer co-extrusion technologies. Meanwhile, during operating, the antimicrobial agent is added to improve antimicrobial ability of the PE pipe. Accordingly, high requirement for antimicrobial ability of the PE pipe for water supply in people's life is met, and the problem that existing antimicrobial pipes are poor in antimicrobial effects is solved.
Description
Technical field
The present invention relates to one water pipe material technical field, particularly relate to a kind of antimicrobial PE tube.
Background technique
Polyethylene resin is that ethene is through being polymerized obtained a kind of thermoplastic resin, extensively be applied to plastic industry, when being especially used as tubing aspect, there is good performance, feedwater polyethylene pipe (PE pipe) is traditional iron and steel tubing simultaneously, the update product of PVC＝polyvinyl chloride drinking-water pipe, because its intensity is high, high temperature resistant, anticorrosive, nontoxic, the feature such as wear-resisting, be widely used in plumbing and manufacture field, but the mold resistance of the existing feedwater PE pipe had commercially is not fine, can pollute when water transmission, therefore, our company adopts a kind of nano-class antibacterial agent to join in PE inner tube layer, thus solve the desirable problem of antibacterial effect on existing market.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of antimicrobial PE tube, and described antimicrobial PE tube can solve the undesirable problem of existing antibacterial pipe antibacterial effect.
For solving the problem, technological scheme of the present invention is a kind of antimicrobial PE tube, described antimicrobial PE tube has double layer construction, the internal layer of the skin that the polyethylene resin comprising 100% forms and the polyethylene resin of 95% and the antimicrobial agent composition of 5%, and internal layer and the outer weight percentage accounting for tubing gross weight are:
Internal layer 8% ~ 12%
Outer 88% ~ 92%.
Further, described nano antibacterial agent is made up of the raw material of following weight proportioning:
1 ~ 2 part, silica 5 ~ 10 parts of Nano Silver powder
1 ~ 3 part, isopropyl titanate 3 ~ 6 parts of propyl alcohol 1 ~ 3 part of glacial acetic acid
Its preparation process is:
(1) silica is sent in reactor, add water and stir, be warmed up to 150 DEG C;
(2) added in reactor by Nano Silver powder subsequently and fully mix with silicon dioxde solution, react, after a period of time, chilling temperature to 50 degree Celsius, obtains mixed material A;
(3) ratio certain to isopropyl titanate, propyl alcohol and glacial acetic acid ammonium is mixed, put on thermostatic electromagnetic stirrer and stir 1h, obtain mixed material B;
(4) mixed material B is instilled in mixed material A, after stirring, drying process is carried out to it;
(5) subsequently mixed material is dried, grinding disposing, obtain finished product anti-bacterial powders.
Further, a period of time of described step (2) is 2h.
Further, the isopropyl titanate of described step (3), propyl alcohol and glacial acetic acid mix in 2:1:1 ratio.
Further, described antimicrobial PE tube preparation process is, first polyethylene resin and antimicrobial agent is granulated through stirrer high stirring at low speed; By obtained particle and the polyethylene resin coextrusion mold being used as outer raw material; Subsequently it is cut, can finished product be obtained.
Compared with prior art, polyethylene resin and antimicrobial agent are first granulated through stirrer high stirring at low speed by the present invention, again by obtained particle and the polyethylene resin coextrusion mold being used as outer raw material, adopt the technology such as high stirring at low speed, two layers of co-extrusion to enhance its corrosion resistance, be easy to the performance such as hot-melt adhesive paste, high strength, with the addition of the antibacterial ability that antimicrobial agent adds PE pipe in operation simultaneously.Thus the antibacterial requirement of height met to feedwater PE pipe in people's life, solve the problem that existing antibacterial pipe antibacterial effect is undesirable.
