To achieve these goals, technological scheme of the present invention is: a kind of composite bactericidal resistance light pipe, it comprises the PP-R external pipe, it is characterized in that: be provided with the antibiotic inner tube of PP-R in the described PP-R external pipe, be provided with PP-R lucifuge mesosphere pipe between the antibiotic inner tube of PP-R external pipe and PP-R.

A kind of manufacturing process of composite bactericidal resistance light pipe, it is characterized in that: described manufacturing process is as follows

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

, with PP-R resin and carbon black on request ratio mix, stirred 2-5 minute with homogenizer, then by the dual-screw-stem machine granulation;

, adopt three-layer co-extruded compound extruded equipment, in main extruder, drop into the outer PP Pipe Compound of PP-R, two auxiliary extruders are extruded PP-R resistance light mesosphere and the antibiotic internal layer of PP-R, processing temperature is controlled between 170 ~ 230 ℃;

, obtain the finished product pipe fitting finally by typing, cooling, cutting.

This case discloses a kind of composite bactericidal resistance light pipe, and it possesses following technique effect: 1, the antibiotic inner tube of PP-R plays antibacterial action, and Escherichia coli, staphylococcus aureus, Candida albicans etc. are had good antibacterial effect; 2, the resistance light action has been managed in PP-R lucifuge mesosphere, avoids the inner layer tube wall bacteria breed, and the product global design is rational in infrastructure, is skillfully constructed, and has good practical effect, compared to existing technologies, has outstanding substantive distinguishing features and remarkable progress.

Fig. 1 is structural representation of the present invention.

Embodiment

The invention will be further described below in conjunction with drawings and Examples.

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

In the specific implementation, the 5%-50% that 3 thickness are the tube wall total thickness is managed in described PP-R lucifuge mesosphere.

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

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

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

In the specific implementation, the PP-R external pipe is comprised of PP-R resin and white mother, wherein the PP-R resin: white mother=100:(1～5).

In the specific implementation, described manufacturing process is as follows:

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

, with PP-R resin and carbon black on request ratio mix, stirred 2-5 minute with homogenizer, then by the dual-screw-stem machine granulation;

, adopt three-layer co-extruded compound extruded equipment, in main extruder, drop into the outer PP Pipe Compound of PP-R, two auxiliary extruders are extruded PP-R resistance light mesosphere and the antibiotic internal layer of PP-R, processing temperature is controlled between 170 ~ 230 ℃;
