Description

A kind of manufacturing process of composite bactericidal resistance light pipe

Technical field

The present invention relates to the technical field of PP-R pipe fitting, specifically a kind of composite bactericidal resistance light pipe, the particularly manufacturing process of its fitting structure and pipe fitting.

Background technique

PP-R is to being again type polypropylene tube, due to widely using of PP-R pipeline, people are not only satisfied with the owned long service life of PP-R pipe-line system, do not tie the advantages such as dirt, also proposed higher requirement, wish that pipeline should have antibacterial bacteriostatic lucifuge performance.

Still there is technological deficiency in PP-R pipe antimicrobial technology of the prior art, cannot realize the effect that long acting antibiotic is antibacterial.

Summary of the invention

A kind of composite bactericidal is the object of the present invention is to provide to hinder the manufacturing process of light pipe, body adopts three layers of patented technology, interior pipe contains one or more antimicrobial agents, antimicrobial factors can be discharged for a long time, realize the effect of long acting antibiotic, mesosphere body is that black avoids pipe, can completely cut off ultraviolet, prevent the algae infestation of inner tubal wall.

To achieve these goals, technological scheme of the present invention is: a kind of manufacturing process of composite bactericidal resistance light pipe, described composite bactericidal resistance light pipe comprises PP-R external pipe, it is characterized in that: in described PP-R external pipe, be provided with the antibacterial inner tube of PP-R, be provided with PP-R lucifuge mesosphere between PP-R external pipe and the antibacterial inner tube of PP-R to manage, described PP-R lucifuge mesosphere tube thickness is the 5%-50% of tube wall total thickness, the antibacterial inner tube thickness of described PP-R is the 0.5%-30% of tube wall total thickness, the antibacterial inner tube of described PP-R is by PP-R resin, antibacterial matrices, look mother composition, PP-R resin: antibacterial matrices: the ratio of weight and number of look mother is=100:(0.1 ~ 8): (1 ~ 5), inorganic antiseptic in described antibacterial matrices is Ag ⁺, Cu ²⁺, Zn ²⁺in one or more, described PP-R lucifuge mesosphere pipe is made up of PP-R resin and carbon black, and described PP-R external pipe is made up of PP-R resin and white mother, wherein PP-R resin: white female ratio of weight and number is 100:(1 ~ 5),

The manufacturing process of described composite bactericidal resistance light pipe is as follows:

, by the antibacterial matrices after PP-R resin, granulation, look mother on request ratio mixing, with homogenizer stir 2-5 minute;

, by PP-R resin and carbon black mixing, stir 2-5 minute with homogenizer, then by dual-screw-stem machine granulation;

, adopt three-layer co-extruded compound extruded equipment, in main extruder, drop into PP-R external pipe PP Pipe Compound, two subsidiary extruder extrude PP-R lucifuge mesosphere pipe and the antibacterial inner tube of PP-R respectively, and processing temperature controls between 170 ~ 230 DEG C;

, finally by sizing, cooling, cutting obtain finished product pipe fitting.

This case discloses a kind of composite bactericidal resistance light pipe and manufacturing process thereof, and it possesses following technique effect: 1, the antibacterial inner tube of PP-R plays antibacterial action, has good antibacterial effect to Escherichia coli, staphylococcus aureus, Candida albicans etc.; 2, resistance light action has been managed in PP-R lucifuge mesosphere, avoids inner layer tube wall bacteria breed, and Total Product project organization is reasonable, is skillfully constructed, has good practical effect, compared to existing technologies, have outstanding substantive distinguishing features and remarkable progress.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

The invention discloses the manufacturing process of a kind of composite bactericidal resistance light pipe, as shown in fig. 1, it comprises PP-R external pipe 1, it is different from prior art and is: be provided with in described PP-R external pipe 1 between PP-R antibacterial inner tube 2, PP-R external pipe 1 and the antibacterial inner tube 2 of PP-R and be provided with PP-R lucifuge mesosphere pipe 3.

In the specific implementation, described PP-R lucifuge mesosphere pipe 3 thickness is the 5%-50% of tube wall total thickness.

In the specific implementation, described PP-R antibacterial inner tube 2 thickness is the 0.5%-30% of tube wall total thickness.

In the specific implementation, the antibacterial inner tube 2 of PP-R is made up of PP-R resin, antibacterial matrices, look mother, PP-R resin: antibacterial matrices: the ratio of weight and number of look mother is=100:(0.1 ~ 8): (1 ~ 5), the inorganic antiseptic in antibacterial matrices is Ag ⁺, Cu ²⁺, Zn ²⁺in one or more.

In the specific implementation, PP-R lucifuge mesosphere pipe is made up of PP-R resin and carbon black, wherein PP-R resin: carbon black=(95 ~ 99.9): (0.1 ~ 5).

In the specific implementation, PP-R external pipe forms wherein PP-R resin by PP-R resin and white mother: white female ratio of weight and number is 100:(1 ~ 5).

In the specific implementation, described manufacturing process is as follows: , by the antibacterial matrices after PP-R resin, granulation, look mother on request ratio mixing, with homogenizer stir 2-5 minute; , by PP-R resin and carbon black mixing, stir 2-5 minute with homogenizer, then by dual-screw-stem machine granulation; , adopt three-layer co-extruded compound extruded equipment, in main extruder, drop into PP-R external pipe PP Pipe Compound, two subsidiary extruder extrude PP-R lucifuge mesosphere pipe and the antibacterial inner tube of PP-R respectively, and processing temperature controls between 170 ~ 230 DEG C; , finally by sizing, cooling, cutting obtain finished product pipe fitting.

Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that the present invention specifically implements to be confined to these explanations above-mentioned.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
