Abstract

The invention relates to a formaldehyde eliminating agent and a preparation method thereof, in particular to an eliminating agent for eliminating free formaldehyde in plate bonding agents. The formaldehyde eliminating agent comprises the following ingredients in percentage by weight: 4 to 8 percent of semicarbazide, 1 to 3 percent of xanthan gum, 5 to 7 percent of chitosan, 12 to 18 percent of stearate and the balance anion water. The ingredients are prepared into the formaldehyde eliminating agent through the steps of drying, dissolution, heating, stirring, mixing and the like. The formaldehyde eliminating agent can fast take reaction with formaldehyde, toxic and harmful byproducts and foreign materials can not be generated, in addition, the slow release effect is realized, and the effect is more durable.

Description

technical field [0001] The invention relates to a purifying agent for toxic substances and a preparation method thereof. Specifically, the present invention relates to a formaldehyde purifying agent and a preparation method thereof. Background technique [0002] Phenolic resin, solid phenolic resin is yellow, transparent, amorphous blocky substance, reddish due to free phenol, specific gravity 1.25-1.30, soluble in alcohol, insoluble in water, stable to water, weak acid and weak alkali solution. It is a resin made by polycondensation of phenol and formaldehyde under catalyst conditions, neutralization and washing with water. Due to the choice of catalyst, it can be divided into two types: thermosetting and thermoplastic. [0003] Phenolic resin has good acid resistance, mechanical properties and heat resistance, and is widely used in anti-corrosion engineering, adhesives, flame retardant materials, grinding wheel manufacturing and other industries. It is widely used in pre...
