Plastic-metal compound pipe and manufacturing method thereof

Abstract

The invention provides a nanometer corrosion-resistant and antibacterial plastic-metal compound pipe. Inner layer plastic of a metal compound pipe is made by combing an inorganic nanometer antibacterial agent and plastic, and outer layer plastic of the metal compound pipe is made by combining an inorganic nanometer preservative and plastic, so that a water sterilizing function is achieved; the outer layer plastic has the characteristics of difficulty in aging, long service life and freeness from pollution; the plastic-metal compound pipe has multiple varieties and applications, and can be applied to different indoor, outdoor, household and industrial production places so as to meet the long-time demands of people on the sanitation and health of water supply pipelines.

Description

technical field [0001] The invention relates to a plastic and metal composite pipe and a manufacturing method thereof. Background technique [0002] In daily life, people inevitably come into contact with various items contaminated by viruses or bacteria, which leads to various diseases. Tap water is a necessity of life for citizens. With the continuous improvement of people's living standards and changes in the environment, the awareness of health care has gradually increased. The water quality of tap water is more and more concerned by everyone. Therefore, the production of various products with antibacterial functions and the avoidance of pathogenic microorganisms on the human body are the development direction for people to reduce or avoid harmful bacteria and promote health. [0003] The inner zinc layer of the galvanized steel pipe is easy to fall off, and the surface of the iron pipe is also easy to rust. The growth of iron-eating bacteria and rusty water will not on...

Problems solved by technology

[0009] Although the water pipe of this structure has a certain bactericidal performance on water quality, the plastic on the outer layer is prone to aging phenomenon due to ultraviolet radiation, so that the metal aluminum is directly exposed to the outside world, and because metal aluminum itself is a kind of chemical property Lively elements are easy to corrode. If the time is longer, the water pipe will be broken due to water pressure, and the service life of the composite pipe will be shortened, causing losses to users.

In addition, this composite pipe also has a disadvantage that there are not many types of composite pipes, only one kind of metal, namely metal aluminum, is used as the main frame of the composite pipe, and the material of the metal aluminum is relatively soft, so the strength of the composite pipe cannot reach the national standard. standard, it cannot be applied to outdoor water pipes, nor is it suitable for large industrial pipes, so its scope of use is narrow and its variety is single, which will bring certain benefits to the development of composite pipe products and the development of enterprises Restrictions also limit its promotion and application in the market

On the other hand, many buildings need to use high-strength, pollution-free, healthy and environmentally friendly water pipes, and some industrial production occasions also require relatively strong, healthy and environmentally friendly pipes, especially in occasions that need to withstand a certain pressure, so its The structure still needs to be improved. Finally, due to the use of pipes with different skeletons, the production method of the composite pipe must also be updated, because the traditional production method of aluminum-plastic composite pipes cannot be used in the new composite pipe with rigid pipes as the skeleton. Therefore, it is very important to develop a new production method for composite pipes with simple process and convenient production.
