Abstract

The invention belongs to a polymer for purifying air and a preparation method and use thereof. The polymer is prepared from the following raw materials: acrylic acid or a derivative thereof, hydrazides compounds, amide and a derivative thereof, carbohydrate, amino acid, silicon oxide or a hydrate thereof, photocatalyst particles, a catalyst and deionized water. The polymer can be dissolved into water, and is not affected by an external factor; the process is applicable to industrial production; the polymer has the advantages of being significant in removal effect on formaldehyde, ammonia gas, benzene and peculiar smell, and stable in absorption.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a polymer for purifying air used for removing harmful gases and deodorizing indoors and in cars, as well as its preparation method and application. Background technique [0002] The stench produced in life, the harmful gas emitted by building materials and decoration materials not only greatly affect people's quality of life, but also directly endanger people's health for a long time. Representative odorous and other easily emitted gases include ammonia, formaldehyde, and benzene. Indoor ammonia mainly comes from concrete additives used in construction such as antifreeze, expansion agent, paint additives, sewer silt, and rot produced in life. These ammonia substances are released as ammonia gas with changes in environmental factors such as temperature and humidity, which can cause a large increase in the concentration of ammonia in the indoor air and endange...
