Abstract
The invention discloses a preparation method of a nano antibacterial pipe and relates to the technical field of building materials. The nano antibacterial pipe is made by adopting the following raw materials in parts by weight: 1-2 parts of nano titanium dioxide antibacterial agent, 92-95 parts of polypropylene random copolymer, 2.5-3.5 parts of toner, 2-3 parts of antioxidant and 2-3 parts of silane coupling agent; and the preparation method comprises the following steps: (A) performing surface treatment on the nano titanium dioxide antibacterial agent by the silane coupling agent, putting the nano titanium dioxide antibacterial agent together with the polypropylene random copolymer, the toner and the antioxidant into an efficient stirrer and stirring, and granulating with a twin-screw extruder; and (B) performing melting and extrusion moulding on the prepared granules by a single-screw extruder, and cooling and setting to obtain the nano antibacterial pipe. Compared with the prior art, the nano titanium dioxide antibacterial agent is added into the raw materials, and the prepared nano titanium dioxide antibacterial agent can remove common bacteria in water to prevent bacteria breeding and guarantee clean and sanitary water quality.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a nano antibacterial tube. Background technique [0002] Engineering plastic pipes have the characteristics of heat resistance, pressure resistance, and heat preservation. At present, engineering plastic pipes are widely used in water supply and drainage pipes of buildings. Clean and hygienic, people will affect their health after drinking. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing a nanometer antibacterial pipe, which can solve the problem of breeding bacteria and microorganisms on the inner surface of the water supply and drainage pipe. [0004] In order to solve the above problems, the technical solution adopted in the present invention is: this nano antibacterial tube is composed of the following raw materials in parts by weight: 1 part to 2 parts of ...
