Abstract

The invention discloses an efficient low-toxicity formaldehyde scavenger containing the following raw material components by weight: 0.5%-5% of hydrazide, 0.1%-5% of a water-soluble ester, 0.5%-10% of a moisture absorbent, 0.1%-0.5% and of a buffer, 0.05%-1% of a surface active agent, 0.02%-0.5% of a preservative and 80%-98% of water. The free hydrazine content in the efficient low-toxicity formaldehyde scavenger product is controlled in the range as low as possible by the manner of fine selection of the hydrazide raw material, control of free hydrazine content, adding of the water-soluble ester, adding of the buffer, and the like, and the efficient low-toxicity formaldehyde scavenger product has better security. The efficient low-toxicity formaldehyde scavenger product is good in formaldehyde removal effect, safe to people and objects, and simple in production process, and can be used for governance of the problem of formaldehyde exceeding the standard in new decorated residence or furniture.

Description

technical field [0001] The invention relates to a high-efficiency and low-toxic formaldehyde scavenger, in particular provides a method for controlling the content of free hydrazine, and is used for the formaldehyde scavenger for treating newly-decorated houses or furniture with formaldehyde exceeding the standard. Background technique [0002] With the use of some indoor building decoration materials, formaldehyde has become the primary pollutant of indoor air in my country. According to the sampling inspection results of China Building Decoration Association in 2013, the average rate of formaldehyde exceeding the standard in newly-decorated residential buildings in my country's cities reaches 70-80%. All kinds of wood-based panels and their products using three-aldehyde glue (that is, urea-formaldehyde, phenolic and melamine-formaldehyde adhesives) as adhesives have always been the main source of formaldehyde. Three-aldehyde products, some preservatives, inks, textiles, le...
