Problems solved by technology

However, the current formaldehyde remover has insufficient duration, high cost, and single removal effect. Basically, it can only remove formaldehyde, a harmful gas. However, other toxic and harmful gases except formaldehyde after house decoration will also cause harm to the human body. It is very harmful, even in the house that is used all the year round, it will produce toxic, harmful gas and peculiar smell

Abstract

The invention discloses a methanol remover and a preparation method thereof. The methanol remover includes 10 to 20 percent of sodium chlorite, 2 to 4 percent of carbamide, 5 to 10 percent of polyacrylate, 6 to 12 percent of polyacrylamide, 2 to 4 percent of guar gum, 5 to 10 percent of other absorbent resin, 1 to 4 percent of citric acid, 1 to 4 percent of boric acid, 2 to 4 percent of monopotassium phosphate, 2 to 4 percent of scenting agent, 2 to 4 percent of borneol and 5 to 10 percent of ethanol. The method of dissolution and stirring is adopted, and a gelatineous solid finished product can be prepared in the end. The invention has the advantages of long duration of time, low cost, effective removal of methanol and a plurality of indoor toxic and harmful gases, and capabilities of sterilization and deodorization. When used, the product is naturally volatilized and does not need to be sprayed and embrocated, dispenses with professional construction teams, and is considerably convenient and safe to use.

Description

technical field [0001] The invention relates to a preparation for eliminating harmful chemical substances and a preparation method thereof, in particular to a formaldehyde remover and a preparation method thereof. Background technique [0002] After the house is decorated, the materials used for the decoration will produce a large amount of carcinogenic, toxic and harmful gases such as formaldehyde, benzene, ammonia, acetone, etc., and it will take three to ten years to completely volatilize. Otherwise, it will seriously affect health and endanger life. At present, we usually use air purifiers to remove toxic and harmful gases in the air after house decoration. Among them, the most commonly used is formaldehyde remover. However, the current formaldehyde remover has not long enough duration, high cost, and single removal effect. Basically, it can only remove formaldehyde, a harmful gas. However, other toxic and harmful gases other than formaldehyde will also cause damage to...
