The high-strength high-temperature-resistant PPR pipe 100 and the pipe system provided by the utility model are specifically described below.
As shown in fig. 1 to 3, a high-strength high-temperature-resistant PPR pipe 100 provided by an embodiment of the present utility model includes:
a vulcanized tripropylene polypropylene base layer 110, a first tripropylene polypropylene layer 120 and a second tripropylene polypropylene layer 130 respectively welded to the inner side and the outer side of the vulcanized tripropylene polypropylene base layer 110;
the heat conducting wire mesh 101 is arranged in each of the first tripropylene layer 120 and the second tripropylene layer 130, a first spandex mesh 140 is embedded in the surface of one side, far away from the vulcanized tripropylene layer 110, of the first tripropylene layer 120, and a second spandex mesh 150 is embedded in the surface of one side, far away from the vulcanized tripropylene layer 110, of the second tripropylene layer 130.
According to the high-strength high-temperature-resistant PPR pipe 100 provided by the utility model, the first tripropylene layer 120 and the second tripropylene layer 130 welded on the inner surface and the outer surface of the vulcanized tripropylene layer 110 are convenient for the cooperation of the vulcanized tripropylene layer 110 and the two tripropylene layers to increase the stability of the pipe structure; the heat conducting silk screen 101 is arranged in the first tripropylene layer 120 and the second tripropylene layer 130, so that the heat of the part of the pipe is conveniently transferred through the heat conducting silk screen 101, and the melting caused by the local overheating of the pipe is avoided, and the high temperature resistance of the pipe is improved; the surfaces of the first polypropylene layer 120 and the second polypropylene layer 130 are embedded into the outer spandex net by hot pressing, so that the first spandex net 140 positioned inside is matched with the second spandex net 150 positioned outside, the tearing strength of the pipe is improved, the strength of the pipe structure is further improved, and breakage of the pipe during bending is avoided.
Preferably, to further secure the high strength and high temperature resistance of the high strength and high temperature resistant PPR pipe 100, the thicknesses of the first tripropylene polypropylene layer 120, the vulcanized tripropylene polypropylene base layer 110 and the second tripropylene polypropylene layer 130 are 0.1 to 0.4mm (e.g. 0.1mm, 0.2mm or 0.4 mm), 0.2 to 0.6mm (0.2 mm, 0.4mm or 0.6 mm) and 0.1 to 0.3mm (e.g. 0.1mm, 0.2mm or 0.3 mm) in this order.
Further, the diameter of the spandex filaments 104 constituting the first and second spandex nets 140 and 150 is 0.01 to 0.05mm (e.g., 0.01mm, 0.02mm, or 0.05 mm).
The polyurethane net formed by the polyurethane filaments 104 with the thickness has better strength, and is easy to be embedded into the surface of the tripropylene layer by hot melting, so that the strength of the pipe is ensured.
Further, the heat conducting wire mesh 101 is formed by connecting a plurality of composite heat conducting wires, and each composite heat conducting wire comprises a copper wire 102 positioned in the middle and a carbon fiber wire 103 wrapped and wound on the surface of the copper wire 102.
The copper wire 102 has the main function of heat conduction, the carbon fiber wire 103 is used for coating the copper wire 102 to increase the roughness of the surface of the copper wire 102, so that the bonding strength of the tripropylene of the heat conduction wire mesh 101 is higher, and the carbon fiber wire 103 is coated without other materials, so that the carbon fiber has better heat conduction. Therefore, the specific structure of the heat conducting wire can ensure that the heat conducting wire mesh 101 and the tripropylene polypropylene layer have good bonding strength and good heat conductivity.

The antimicrobial tripropylene polypropylene layer 160 is located at the innermost side of the tubing and is capable of providing antimicrobial action to prevent bacteria from propagating within the tubing during liquid transport using the high strength, high temperature resistant PPR tubing 100.
Further, the thickness of the antimicrobial tripropylene polypropylene layer 160 is 0.1-0.3 mm (e.g., 0.1mm, 0.2mm or 0.3 mm).
The antibacterial tripropylene polypropylene layer 160 with the thickness can play an obvious antibacterial role on the basis of not increasing the thickness of the pipe as much as possible.
Further, a side surface of the second tripropylene layer 130 remote from the base vulcanized tripropylene layer 110 is heat-fused with a heat-insulating polyester plastic layer 170.
The heat-insulating polyester plastic layer 170 protects the pipe and increases the high temperature resistance of the pipe.
Further, the thickness of the insulating polyester plastic layer 170 is 1 to 2mm (e.g., 1mm or 2 mm).
The heat-insulating polyester plastic layer 170 with the thickness has a better protection effect.
Further, the heat-insulating polyester plastic layer 170 is formed by winding an elongated polyester plastic sheet 171 having a width of 10mm around the second polypropylene-tripropylene layer 130.
In summary, according to the high-strength high-temperature-resistant PPR pipe provided by the utility model, the first tripropylene layer and the second tripropylene layer welded on the inner surface and the outer surface of the vulcanized tripropylene polypropylene base layer are convenient to match with the vulcanized tripropylene polypropylene base layer and the two tripropylene layers to increase the stability of the pipe structure; the heat conducting silk screens are arranged in the first tripropylene layer and the second tripropylene layer, so that local heat of the pipe is conveniently transferred through the heat conducting silk screens, and melting caused by local overheating of the pipe is avoided, and the high temperature resistance of the pipe is improved; the surfaces of the first tripropylene layer and the second tripropylene layer are embedded into the outer spandex net through hot pressing, so that the first spandex net positioned inside is matched with the second spandex net positioned outside, the tearing strength of the pipe is improved, the strength of the pipe structure is further improved, and breakage of the pipe during bending is avoided.
