Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention will be further described:

[0009] See attached figure 1 The inner layer 1 is an antibacterial material mixed with 10% inorganic antibacterial agent and 90% polyethylene, and the outer layer 2 is reinforced polyethylene mixed with 85% polyethylene and 15% glass fiber with a length of 10mm. The co-extrusion process forms a double-layer structure in which the inner layer 1 and the outer layer 2 are combined.

[0010] See attached figure 1 , firstly, the antibacterial material mixed with 10% inorganic antibacterial agent and 90% polyethylene is fed into the barrel of the extruder,

[0011] Again, 85% polyethylene and 15% glass fibers with a length of 10 mm were mixed and fed into another extruder barrel.

[0012] The two different materials are fed into their respective extruders, heated and smelted, and compounded by co-extrusion to form a double-layer structure of the inner layer 1 and the outer la...

Abstract

The invention discloses a coextrusion reinforced polyethylene antibacterial composite pipe. The coextrusion reinforced polyethylene antibacterial composite pipe is characterized in that an inner layeris made of an antibacterial material mixed by 10 % inorganic antibacterial agent and 90 % polyethylene, an outer layer is reinforced polyethylene mixed by 85 % polyethylene and 15 % glass fiber witha length of 10 mm, and a composite double-layer structure of the inner layer and the outer layer is formed by a coextrusion process method. Firstly, the relatively soft defect of the material is overcome, the rigidity is increased, thus the same effect of laying an open pipe and a concealed pipe is achieved, meanwhile a composite pipe with an antibacterial effect is formed by coextrusion, and thequality of water supply is effectively ensured.

Description

technical field [0001] The invention discloses a co-extruded reinforced polyethylene antibacterial composite pipe, which relates to the technical field of composite pipe processing and manufacturing and is applied to water supply. Background technique [0002] At present, domestically produced polyethylene and polypropylene pipes are relatively soft due to the nature of the material. As a decoration for water supply, only hidden pipes or increased thickness can be used to cover up the defects of the pipes. Arranging the hidden pipes has not only damaged the wall surface, but also increased man-hours and expenses. What also have laid open pipe for saving time and effort, because its bending degree is big, very not attractive in appearance. How to enhance the rigidity of polyethylene and polypropylene pipes and produce popular antibacterial composite pipes is a subject that people in the industry are studying. Contents of the invention [0003] The purpose of the present i...
