Antibacterial PPR pipe

Abstract

The invention belongs to the technical field of pipes and particularly relates to an antibacterial PPR pipe. The antibacterial PPR pipe consists of the following raw materials in percent by weight: 0.3-2 percent of a silica-loaded nano-silver antibacterial agent, 94-95.7 percent of PPR raw material, 2 percent of toner and 2 percent of an antioxidant, wherein the silica-loaded nano-silver antibacterial agent is prepared by mixing and stirring silver nitrate, ethyl orthosilicate, absolute ethyl alcohol and ammonia water and reducing the mixture through a reducing agent. The nano-silver particles are well dispersed in the PPR pipe, and a strong antibacterial effect of the nano-silver particles is effectively exerted, so that the nano-silver ion amount is reduced, and the cost is reduced. The bacterial growth is effectively avoided, common bacteria in the water body are eliminated, and water in the pipeline is kept sanitary and clean; the process is simple, the reaction conditions are mild, the cost is low, and great convenience is brought to industrial production and popularization of the PPR pipe.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to an antibacterial PPR pipe. Background technique [0002] PPR pipes have the advantages of heat resistance, pressure resistance, heat preservation and energy saving, and long service life. They have been widely used in water supply systems in buildings. Some substances similar to mucous membranes will form a large amount of scale impurities when they are severely derivatized, which is difficult to wash away through the natural pressure of water, seriously affecting water quality. Therefore, it is necessary to improve the antibacterial properties of PPR plastic pipes. Silver ions and silver-containing compounds can kill or inhibit bacteria, viruses, algae and fungi. It has the effect of fighting diseases, and is also known as a biophilic metal. The most important compound of silver is silver nitrate. In medical treatment, an aqueous solution of silver nitrate is commonly used as ey...

Problems solved by technology

At present, the methods for preparing silver-loaded silica antibacterial materials mainly include calcination and chemical reduction. The calcination method has the disadvantages of complicated process and long reaction time. If the chemical reduction method can be used to directly adsorb silver ions on silica in solution The surface can be reduced to simple silver at the same time, the process is simple, the reaction conditions are mild, and the cost is low, which will greatly facilitate its production and promotion in industry
