Household formaldehyde elimination agent

Abstract

The invention discloses a household formaldehyde elimination agent which mainly comprises an adsorbent carrier loaded with a hydrazine compound and a reaction accelerant, wherein the mass part ratio of the hydrazine compound to the reaction accelerant to the adsorbent carrier is (0.032-0.144) to (0.008-0.01) to 1. According to the household formaldehyde elimination agent, a mode that the hydrazine compound and the reaction accelerant are cooperatively used is adopted, and formaldehyde in air is physically adsorbed by the adsorbent carrier, chemically reacts with the hydrazine compound on the adsorbent carrier and finally is converted into a nontoxic and tasteless substance, so that formaldehyde is radically eliminated; the formaldehyde elimination agent is convenient to use and pollution-free; the practice proves that the air quality is remarkably improved after the formaldehyde elimination agent is used; moreover, the formaldehyde elimination agent is low in price and especially suitable for daily use in families.

Description

technical field [0001] The invention belongs to the field of formaldehyde removal, in particular to a household formaldehyde remover. Background technique [0002] Formaldehyde has always been considered as the number one suspected carcinogen in indoor pollution, and it usually comes from decoration, decoration materials, furniture and coatings, etc., especially wood-based panels and the adhesives they use. Wood-based panels, plywood, particleboard, fiberboard, composite flooring, etc., they use phenolic and urea-formaldehyde resins containing formaldehyde in the production process. According to statistics, more than 90% of domestic wood-based panels are pressed with urea-formaldehyde glue, so of course there will be problems during application. Free formaldehyde, used in furniture manufacturing or other panel applications, often has a certain impact on the human body. In the actual application process, the reasons for the generation of free formaldehyde include the followi...

Problems solved by technology

[0007] In actual use, the volatilization time of free formaldehyde generally lasts for 10 to 15 years. In the above two formaldehyde scavengers, the active ingredients added are limited. Once the effectiveness fails, free formaldehyde in the wood-based panel will still be released in large quantities. come out, causing indoor air pollution. In addition, when the formaldehyde scavenger reacts incompletely with formaldehyde, it may also generate other toxic substances and cause secondary pollution.
