Abstract
The invention relates to a PP-R (polypropylene random) anti-bacterial tube which comprises PP-R resin and an inorganic antibacterial agent and is molded through the steps of adding the inorganic anti-bacterial agent into the PP-R base resin and then milling mixing and injection molding through an injection molding machine. The weight part proportion of the PP-R resin to the inorganic anti-bacterial agent is 100:1-8 and preferentially 100:5; wherein the inorganic antibacterial agent is silver series inorganic anti-bacterial agent; and the anti-bacterial activity value of the PP-R anti-bacterial tube to escherichia coli is 2.5 or above 2.5, and the anti-bacterial activity value of the PP-R anti-bacterial tube to staphylococcus aureus is 3.4 or above 3.4. The PP-R anti-bacterial tube not only has the advantages of light weight, good strength, corrosion resistance, no scaling, strong service life and the like of a common plastic tube, but also has the advantages of sanitation, non-toxicity, thermal preservation, energy saving, attractive appearance, convenient installation, reliability, long service life and the like.
Description
Technical field
The present invention relates to a kind of PP-R pipe fitting, specifically relate to the antibiotic pipe fitting of a kind of PP-R.
Background technique
PP-R adopts atactic copolymerized polypropene through being extruded as tubing to being three type polypropylene tube again, and injection moulding becomes pipe fitting, is the novel plastic pipeline product of Europe Application and Development at the beginning of the nineties, and it has good shock resistance and long-term creep performance.
Because being extensive use of of PP-R pipeline, people not only are satisfied with advantages such as the owned long service life of PP-R pipe-line system, non-scaling, they have higher requirement, be that pipeline has the antibacterial bacteriostatic performance, can remove bacterium harmful in the whole tubing, particularly Escherichia coli and staphylococcus aureus.In the antibiotic pipe-line system of entire PP-R the antibacterial effect requirement is arranged, thereby the tubing in the pipe-line system, pipe fitting also all must have antibacterial effect, particularly the antibacterial effect to the various pipe fitting that plays interconnect function in the pipe-line system requires more strict.
Summary of the invention
Technological scheme to be solved by this invention provides the antibiotic pipe fitting of a kind of PP-R, and this pipe fitting can be connected with PP-R antibacterial pipe material hot melt, and attachment security is reliable.
In order to achieve the above object, the present invention adopts following technological scheme to realize:
The antibiotic pipe fitting of a kind of PP-R comprises PP-R resin and inorganic antiseptic, by add inorganic antiseptic in the PP-R base resin, passes through the mixing injection molded shape of injection machine then.
The parts by weight ratio of described PP-R resin and inorganic antiseptic is 100: 1-8.
The parts by weight ratio of described PP-R resin and inorganic antiseptic is preferably 100: 5.
Described inorganic antiseptic is a silver-based inorganic antibacterial agent.
The antibiotic pipe fitting of described PP-R is more than 2.5 or 2.5 to colibacillary antibacterial activity value, is more than 3.4 or 3.4 to the antibacterial activity value of staphylococcus aureus.
The antibiotic pipe fitting of PP-R of the present invention the advantage such as general plastic tube light weight, intensity are good, corrosion-resistant except having, non-scaling, working life are strong, also has following main feature:
(1) health is nontoxic: this product belongs to green building material, can be used for purified water and quotes water piping system;
(2) heat preservation energy-saving: thermal conductivity only is one of percentage of metal tube, and it is splendid to be used for the hot water pipeline heat preservation and energy conservation effects;
(3) beautiful shape: the product inside and outside wall is smooth, and the flowing water resistance is little, and is honorable soft, handsome in appearance;
(4) easy for installation, reliable: adopt hot melt to connect, need not mantle fiber, the several seconds can be finished a joint and be connected;
(5) long service life: can reach more than 50 years working life at normal temperatures.
