Problems solved by technology

However, PVC pipes also have certain defects when used as water supply and drainage pipes. On the one hand, because PVC materials are flammable polymers, pipes made of PVC materials generally have the defect of poor flame retardancy
For the safety of use, it is often necessary to add flame retardants to PVC pipes to improve its flame retardant performance. Currently, the frequently used halogen flame retardants have been gradually discontinued due to environmental pollution problems, and PVC after adding halogen-free flame retardants Pipes usually have the defects of poor flame retardant effect and easy to reduce the mechanical properties of PVC pipes
On the other hand, during the long-term use of PVC pipes, coalescing scale will be deposited on the inner wall, which is easy to breed bacteria and affect the safety of PVC pipes as drinking water pipes
At present, the existing antibacterial PVC pipe mainly realizes its antibacterial function by adding inorganic nano-antibacterial agent, but it is difficult for the inorganic nano-antibacterial agent to disperse evenly in the raw material of PVC pipe matrix, which inhibits its antibacterial performance to a certain extent

preparation example Construction

[0024] The preparation method of the pomegranate peel extract is as follows: weighing the pulverized pomegranate peel, adding ethanol solution with a volume ratio of 35 times, ultrasonically assisted extraction, filtering, and then concentrating under reduced pressure until the ethanol is completely volatilized to obtain the pomegranate peel extract.

[0025] The preparation method of silane coupling agent modified hydrotalcite is as follows: add 5% of its mass silane coupling agent to hydrotalcite, put it into a mixer, mix and stir at 500r / min for 3min, and then dry it under vacuum at 80°C. Among them, the hydrotalcite is magnesium aluminum hydrotalcite with an average particle size of 0.6 μm, and the silane coupling agent is γ-methacryloxypropyltrimethoxysilane, which is prepared as an aqueous solution with a mass concentration of 1%.

Description

technical field [0001] The invention belongs to the technical field of pipelines, in particular to an antibacterial pipeline with flame retardancy. Background technique [0002] In 2014, plastic pipes accounted for 54% of the world's pipeline market, and even more in developed countries and regions such as the United States, Japan, and Europe. PVC pipes are the most widely used plastic products, reaching 62%. In the past ten years, with the rapid growth of the domestic economy and the vigorous development of the pipeline industry, the domestic plastic production has increased from less than 200,000 tons in 1990 to 2 million tons in 2014, with an annual growth rate of 15%, ranking first in the world. No. 1. In 2014, the output of PVC pipes reached 1.2 million tons, ranking first in the output of various plastic pipes. At present, PVC pipes are playing an increasingly important role in many fields such as water supply and drainage pipes, cable casings, irrigation pipes, engi...
