Preparation method of active additive component for photocatalyst

Abstract

The invention discloses a preparation method of an active additive component for a photocatalyst. The preparation method comprises the following steps: separately weighing nano-titanium dioxide, nano-silver powder, mineral mixed powder, a traditional Chinese medicine extract, sodium carbonate, a dispersant and a penetrant according to weight parts, and adding the weighed materials in deionized water to obtain a mixture A1; uniformly mixing the mixture A1 in a sealed environment, then placing the mixture in an environment of 30-45 DEG C, and keeping the temperature for 20-40 min to obtain a mixture A2; weighing TRAMP active molecules according to a weight part, and adding the weighed TRAMP active molecuels to the mixture A2 to obtain a mixture B; uniformly mixing the mixture B, placing themixture B in an environment of 20-35 DEG C, and keeping the temperature for 15-25 min to obtain a photocatalyst active additive C; and canning the photocatalyst active additive C and carrying out refrigeration. The preparation method of the photocatalyst active additive provided by the invention is simple, and the photocatalyst active additive can be used to carry out purification treatment on formaldehyde and the like.

Description

technical field [0001] The invention relates to the technical field of photocatalyst active additives, in particular to a preparation method for photocatalyst active additive components. Background technique [0002] In the process of home decoration, some pollution will be caused more or less. At present, the main pollutant of home decoration is formaldehyde; wood-based panels, paints, carpets, and furniture used in home decoration will contain formaldehyde, which is the main formaldehyde pollution for new homes. Question: The incubation period of formaldehyde and other harmful substances indoors is 10-15 years, and its release rate will also change with temperature and humidity; according to statistics, the average time spent indoors in a person’s life is as high as 80%, and formaldehyde and other harmful substances The long incubation period provides a huge "opportunity" for the annual increase of leukemia, cancer and other diseases; usually people simply purify the room ...

Question: The incubation period of formaldehyde and other harmful substances indoors is 10-15 years, and its release rate will also change with temperature and humidity; according to statistics, the average time spent indoors in a person’s life is as high as 80%, and formaldehyde and other harmful substances The long incubation period provides a huge "opportunity" for the annual increase of leukemia, cancer and other diseases; usually people simply purify the room by ventilating the room or placing green plants, but the effect is not obvious; The photocatalyst, which is a representative semiconductor material with photocatalytic function, can effectively decompose formaldehyde, benzene, ammonia, etc.; the photocatalyst can also oxidize and remove nitrogen oxides, sulfides, and various odors in the atmosphere to purify the air. ; Photocatalysts are low in cost and stable in chemical properties, and have been used more and more in indoor purification in recent years; Working under weak light greatly reduces the purification efficiency of the photocatalyst
