Abstract

The invention discloses a modified resin material for purifying domestic water and a preparation method thereof, which consists of the following components by weight percentage: 88-97.6% of polypropylene; 2-10% of purification modifier; 0.2% of heat stabilizer -1%; processing aid 0.2-1%; the present invention utilizes the selective adsorption of Zr to fluorine to prepare divinylbenzene and vinylphenyl-N,N,N-trimethyl loaded Zr(IV) ammonium hydroxide polymer, and use it as a purification modifier to modify the polypropylene material, and prepare a modified resin material for purifying domestic water with fast adsorption speed and strong adsorption force, and the obtained modified resin material can be used to prepare Domestic water pipes, containers and other products have improved the functionality of polypropylene materials and increased the application fields and added value of polypropylene materials.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified resin material for purifying domestic water and a preparation method thereof. Background technique [0002] Water is an important part of the human body. As people pay more and more attention to health and diseases, they pay more attention to water quality. Due to the discharge of fertilizers and industrial waste, as well as the large amount of fluorine in rocks in some parts of northern my country, the fluorine content in tap water is relatively high. Excessive fluoride intake can cause chronic fluorosis in the body and affect the health of bones and teeth. At present, the commonly used technologies for removing fluorine in water include precipitation method and adsorption method, and the precipitation method requires a large amount of precipitant and the sediment will cause secondary pollution. The chemical adsorption method has relatively flexible adsorb...
