Abstract

The invention relates to the technical field of melamine adhesives, particularly a melamine adhesive formula for absorbing and decomposing formaldehyde in air and a preparation technique thereof. The melamine adhesive is composed of the following components in percentage by weight: 35-48% of formaldehyde, 28-32% of melamine, 3-7% of diethylene glycol, 7-15% of water, 3-7% of amine, 0-1% of sodium hydroxide, 4-7% of aldehyde remover and 0-5% of nano silicon dioxide. The preparation method comprises the following steps: sequentially adding formaldehyde, melamine, diethylene glycol, sodium hydroxide, aldehyde remover, nano silicon dioxide and amine into a preset weight of water, and stirring. Compared with the prior art, the furniture, floor board and decorative board using the melamine adhesive have the capacity for eliminating formaldehyde in air, and have high formaldehyde removal efficiency; the melamine adhesive is suitable for operation of the existing plant production equipment; and the melamine adhesive has the protective functions of scratch resistance, scoring resistance, wear resistance, water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of melamine glue, in particular to a formula of melamine glue for absorbing and decomposing formaldehyde in the air and a preparation process thereof. Background technique [0002] Formaldehyde is a volatile organic compound, colorless, with a special smell, slightly heavier than air, and easily soluble in water. Formaldehyde has an important impact on human health and has a strong irritating effect on the eyes, respiratory tract, human mucous membranes and skin; acute poisoning can cause symptoms such as tearing, runny nose, coughing, and various respiratory diseases; chronic inhalation of low concentrations can cause persistent headaches , weakness, insomnia, etc.; long-term skin contact can cause dermatitis, which will have adverse effects on the human respiratory system, digestive system and central nervous system, resulting in abnormal lung and liver immune function. Formaldehyde is so harmful to the h...
