Abstract

The invention discloses an antibacterial polyvinyl chloride tube material. The antibacterial polyvinyl chloride tube material comprises polyvinyl chloride, sulfonated polyethersulfone, styrene-butadiene rubber, butadiene-acrylonitrile rubber, high density polyethylene, nanometer zinc oxide, modified nanometer titanium dioxide, attapulgite, nanometer montmorillonite, epoxidized butyl oleate, tri-isopropylphenyl phosphate, zinc stearate, zinc azelate, calcium pimelate, pentaerythritol, lanthanum 2-ethyloctoate, dimethyltin bis(isooctylmercaptoacetate), an anti-oxidant, 2-n-octyl-4-isothiazolin-3-one and p-tert-butylcatechol. A preparation method of the modified nanometer titanium dioxide comprises adding ferric nitrate and nanometer titanium dioxide into deionized water, stirring the solution at a room temperature for 50-60h, carrying out aging for 25-30h, carrying drying, carrying out grinding, carrying out calcination at a temperature of 450-500 DEG C for 2-3.5h and then cooling the product to the room temperature. The antibacterial polyvinyl chloride tube material has good bacterinertness, heat resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride, in particular to an antibacterial polyvinyl chloride pipe. Background technique [0002] As the second largest synthetic material, polyvinyl chloride has the advantages of strong corrosion resistance, easy bonding, cheap and easy to obtain, good chemical stability, and resistance to microbial erosion. It is one of the most commonly used pipes. With the increase of the application range of polyvinyl chloride pipes, more and more fields have higher requirements on the performance of polyvinyl chloride pipes used. The existing polyvinyl chloride pipes are still not very heat-resistant and antibacterial. Ideal, modification required. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes an antibacterial polyvinyl chloride pipe, which has good antibacterial properties, excellent heat resistance and aging resistance...
