Abstract
A co-extrusion enhanced polyethylene antibacterial composite pipe. The method is characterized in that: the inner layer is made of an antibacterial material mixed by 10% of inorganic antibacterial agent and 90% of polyethylene, the outer layer is made of reinforced polyethylene mixed by 85% of polyethylene and 15% of glass fiber with the length of 10mm, and a double-layer structure formed by compounding the inner layer and the outer layer is formed by adopting a co-extrusion process method. The defect that the material is relatively soft is overcome, the rigidity is increased, the same effect of laying the exposed pipe and the hidden pipe is achieved, meanwhile, the composite pipe with the antibacterial effect is formed through co-extrusion, and the quality of water supply is effectively guaranteed.
Description
Technical Field
The invention discloses a co-extrusion enhanced polyethylene antibacterial composite pipe, relates to the technical field of composite pipe processing and manufacturing, and is applied to water supply.
Background
At present, polyethylene and polypropylene pipes produced in China are relatively soft due to the properties of the materials, and the defects of the pipes can be covered only by arranging concealed pipes or increasing the thickness of the concealed pipes when the polyethylene and polypropylene pipes are used for water supply decoration. The arrangement of the concealed pipes not only damages the wall surface, but also increases the working hours and the cost. Some open pipes are laid for saving time and labor, and are not beautiful due to large bending degree. How to enhance the rigidity of polyethylene and polypropylene pipes and produce popular antibacterial composite pipes is a subject of research by the industry people.
Disclosure of Invention
The invention aims to overcome the defects, and the co-extrusion enhanced polyethylene antibacterial composite pipe with the outer layer of enhanced polyethylene and the inner layer of antibacterial material is formed by modifying polyethylene, increasing the rigidity of the polyethylene and co-extruding the polyethylene and the antibacterial material.
The technology is realized as follows: the method is characterized in that: the inner layer is made of an antibacterial material mixed by 10% of inorganic antibacterial agent and 90% of polyethylene, the outer layer is made of reinforced polyethylene mixed by 85% of polyethylene and 15% of glass fiber with the length of 10mm, and a double-layer structure formed by compounding the inner layer and the outer layer is formed by adopting a co-extrusion process method.
The obvious advantages and effects after the technology is implemented are as follows: the defect that the material is relatively soft is overcome, the rigidity is increased, the same effect of laying the exposed pipe and the hidden pipe is achieved, meanwhile, the composite pipe with the antibacterial effect is formed through co-extrusion, and the quality of water supply is effectively guaranteed.
Drawings
FIG. 1 is a schematic sectional view of the present invention,
wherein, 1-inner layer and 2-outer layer.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
referring to the attached drawing 1, the inner layer 1 is made of an antibacterial material mixed by 10% of inorganic antibacterial agent and 90% of polyethylene, the outer layer 2 is made of reinforced polyethylene mixed by 85% of polyethylene and 15% of glass fiber with the length of 10mm, and a double-layer structure formed by compounding the inner layer 1 and the outer layer 2 is formed by adopting a co-extrusion process method.
Referring to fig. 1, first, an antibacterial material mixed with 10% of an inorganic antibacterial agent and 90% of polyethylene is fed into a barrel of an extruder,
again, 85% polyethylene and 15% glass fibers having a length of 10mm were mixed and fed into the barrel of another extruder.
The two different materials are fed into respective extruders for heating and smelting, and are compounded by adopting a co-extrusion process method to form a double-layer structure of the inner layer 1 and the outer layer 2.
