Abstract

The invention discloses a water treatment sponge material. Modified polyester undergoes melt-blown spinning and is braided to obtain water treatment sponge, and a modifier is added to regulate the structure of a fiber and improve the strength of the fiber; a cross-linking layer is formed on the surface of the fiber through rapid cross-linking, and nano-particles are introduced to further guarantee the strength of the fiber and improve the adsorption capacity of the water treatment sponge. The above water treatment fiber disclosed in the invention has a large content of oil suction groups, the application range of the water treatment sponge made by using the water treatment fiber can be greatly widened, and the water treatment sponge plays a positive role in the field of organic liquid pollution treatment; and a preparation method of the water treatment sponge material has the advantages of simplicity, easy operation and short preparation time, and the water treatment sponge prepared through the method has the characteristics of excellent adsorption performance, good strength, small density and repeated use, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a manufacturing technology of an environment-friendly material, in particular to a water treatment sponge material, which belongs to the field of polymer material preparation. Background technique [0002] Human beings need more and more water resources, but with the development of industrialization, the problem of global environmental pollution is becoming more and more serious, and a large amount of garbage is dumped into rivers every day. In recent years, with the rapid development of modern industry, a large amount of untreated or substandard sewage is directly discharged, causing severe damage to the water environment, leading to deterioration of water quality, and the problem of water quality-type water shortage has become increasingly prominent. In this critical situation, water treatment technology is in urgent need of rapid development. Among them, organic waste liquids such as benzene, kerosene, gasoline and other oi...
