Antistatic low-light photocatalyst type formaldehyde remover and preparation method thereof

Abstract

The invention discloses an antistatic low-light photocatalyst type formaldehyde remover. The antistatic low-light photocatalyst type formaldehyde remover comprises modified water-based polyurethane emulsion, water-soluble cyclodextrin, carboxylic butadiene-styrene modified latex, antistatic agent, formaldehyde decomposition enzyme, water-based hyperdispersant, nano porous silicon dioxide, n-butanol and stabilizer. The indoor formaldehyde purifying agent having favorable stability, high safety and environment friendliness can be prepared according to the formula disclosed by the invention; the purifying agent can be favorably attached to a brushed finish, has the functions of continuously resisting bacteria, deodorizing and decomposing indoor formaldehyde and other toxic gas, and can effectively avoid the problem of a reduced purification effect caused by shedding due to infirm paint adsorption; the decomposition enzyme disclosed by the invention can realize the low-light catalyst reactivity having the highest light utilization ratio in the world so far, has less dependence on a light source, and can be attached to a place close to a light source to maximally give play to low-light or even lightless decomposability; and the product disclosed by the invention also has a favorable antistatic effect, and prevents the surface of a coating from adsorbing dirt to realize long-time efficient catalyst decomposition.

Description

technical field [0001] The invention belongs to the field of indoor air purification, and specifically designs an antistatic formaldehyde purifier with good purification effect and environmental protection characteristics and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the requirements for indoor beautification are getting higher and higher. However, many interior decoration materials contain harmful substances such as formaldehyde, which will be released slowly during the use of decoration materials, causing harm to human health. Gradually, health and environmental protection issues have attracted everyone's attention, and the purification of indoor air has also attracted increasing attention. People mostly use various new materials such as wood-based panels for interior decoration, but plywood, particleboard, density board, blockboard and other wood-based panel products made of urea-formaldehyde ...

AI Technical Summary

Problems solved by technology

[0003] Formaldehyde is a substance with high toxicity, which can be converted into methanol in the human body. Methanol accumulates in the human body to stimulate the central nervous system, and is toxic to the human immune system and liver. Slight formaldehyde poisoning can cause irritation to the conjunctiva and mucous membranes of the respiratory tract. And produce tears, runny nose, cause conjunctivitis, pharyngitis, asthma, bronchitis and allergic diseases; poisoned formaldehyde poisoning will cause many cancers, so it is very necessary for the cleaning of indoor formaldehyde, but the current market The existing formaldehyde removal products on the market still have problems such as low removal efficiency, insufficient removal, and activity maintenance time period.
