Abstract
The invention relates to a nano antibacterial PP-R composite pipe and a manufacturing method thereof and belongs to the technical field of building materials. The traditional PP-R pipes, on one hand, has inadequate strength and large coefficient of inertia expansion, and, on the other hand, cannot suppress the growth of bacteria and deteriorates water as a bacterium film is on the inside surface of the pipe after long-term use. Aiming at overcoming the drawbacks, the invention designs a composite pipe, which comprises a common PP-R outer pipe layer and is characterized in that: an inner pipe layer is PP-R loaded with a silver ion antibacterial agent; and a composite reinforcing layer blended with glass fibers and the PP-R is arranged between the inner and outer pipe layers. The manufacturing method of the nano antibacterial PP-R composite pipe comprises: connecting three layers of composite molds and three plastic extruding machines; after the raw materials are heated to a corresponding temperature, sequentially starting the three extruding machines to co-extruding the three layers to make a pipe blank; and subjecting the pipe blank to vacuum sizing, spray cooling, surface drying, laser code spray, fixed length cutting and end milling to obtain the nano antibacterial PP-R composite pipe. Trial use shows that the nano antibacterial PP-R composite pipe of the invention has the advantages of high strength, small coefficient of inertia expansion and remarkable antibacterial effect.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of antibiotic plastic pipe and manufacture method thereof, particularly a kind of nano antibacterial PP-R composite pipe and manufacture method thereof.
Background technique
Existing P P-R (atactic copolymerized polypropene resin) pipe exists insufficient strength, defective that linear expansion coefficient is big on the one hand, can not suppress its growth to the bacterium in the water quality on the other hand, can adhere to, grow microorganism through the long-term back internal surface that uses, form mycoderm, cause deteriorating water quality.This shows, at the deficiencies in the prior art, design a kind of intensity height, linear expansion coefficient is little, nano antibacterial PP-R composite pipe and manufacture method thereof that again can bacteria growing inhibiting be necessary.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, design a kind of intensity height, linear expansion coefficient is little, nano antibacterial PP-R composite pipe and manufacture method thereof that again can bacteria growing inhibiting.
The object of the present invention is achieved like this: a kind of nano antibacterial PP-R composite pipe and manufacture method thereof, wherein nano antibacterial PP-R composite pipe includes common PP-R external tube layer, the pipe layer constitutes for being added with the PP-R that carries silver-colored silver ion antimicrobial agent in it is characterized in that, is that the compound reinforced layer of glass fibre and PP-R blend constitutes between the inner and outer pipe layer.
Described nano antibacterial PP-R composite pipe and manufacture method thereof, manufacture method wherein is characterized in that comprising the steps:
A. select corresponding three layers of composite dies for use according to the tubing specification, interconnect with three plastic extruders, and preheating;
B. start charging equipment, the compound reinforced layer of the common PP-R external tube layer of correspondence, glass fibre and PP-R blend, the raw material that is added with the interior pipe layer that carries silver-colored silver ion antimicrobial agent PP-R are sucked the hopper inner drying preheating of extruder respectively;
C. wait for extruder and mould and die preheating after relevant temperature, start three extruders successively, through the three-layer co-extruded nano antibacterial PP-R composite pipe pipe that is composited;
D. pipe promptly obtains the nano antibacterial PP-R composite pipe finished product after vacuum sizing, spray cooling, dry tack free, laser coding, scale cutting, end mill and check.
The nano antibacterial PP-R composite pipe that the invention process obtains has shown following advantage through trying out:
1. intensity height, linear expansion coefficient are little.Owing to be the compound reinforced layer of glass fibre and PP-R blend between the inner and outer pipe layer, the intensity of whole nano antibacterial PP-R composite pipe increases substantially, and linear expansion coefficient also is reduced to 1/3rd of common PP-R pipe.
2. has tangible antibacterial effect.Because interior pipe layer is to be added with the PP-R that carries silver-colored silver ion antimicrobial agent to constitute, the physicochemical property of nanometer material uniqueness has determined that its self-cleaning anti-pollution performance is good, and year silver-colored silver ion antimicrobial agent in the internal layer slowly discharges and guaranteed long antibiotic, bactericidal action.
