Embodiment 1

[0016] The wood-based panel glue that can reduce the content of human toxic gas and free aldehyde in this implementation, the glue is the preparation method of urea-formaldehyde resin: urea and 37% formaldehyde aqueous solution are polycondensed under the catalysis of acid or alkali to obtain linear urea-formaldehyde oligomers, react at 90 ° C, The molar ratio of formaldehyde to urea is 1.5 to obtain a soluble resin, and then add bamboo charcoal and activated carbon to the soluble resin.

Embodiment 2

[0018] The artificial board glue that can reduce the content of human toxic gas and free aldehyde in this implementation, the glue is the preparation method of urea-formaldehyde resin: the molar ratio of urea and formaldehyde is 1:1.5, after it is completely dissolved at pH=8, 30°C , then add 0.54% urea oxalic acid and 0.33% oxalate ester, exothermic reaction occurs immediately, the temperature rises, add bamboo charcoal, activated carbon, keep the temperature at 55°C, and strictly control the pH=6, after 60min, the obtained The required urea-formaldehyde resin.

Embodiment 3

[0020] The wood-based panel glue that can reduce the content of human toxic gas and free aldehyde in this implementation, the glue is the preparation method of urea-formaldehyde resin: urea and 37% formaldehyde aqueous solution are polycondensed under the catalysis of acid or alkali to obtain linear urea-formaldehyde oligomers, 100 ° C reaction, The molar ratio of formaldehyde to urea is 2.0 to obtain a soluble resin, and then add bamboo charcoal and activated carbon to the soluble resin.

Abstract

The invention relates to artificial board glue and particularly relates to artificial board glue capable of reducing contents of human poisonous gas and free formaldehyde. According to the artificial board glue capable of reducing contents of human poisonous gas and free formaldehyde, bamboo charcoal and activated carbon are added into the glue. The artificial board glue has the beneficial effects that the contents of poisonous gas and free formaldehyde can be effectively reduced and the property of the glue is not affected. Therefore, the artificial board glue is worth of popularization.

Description

[0001] (1) Technical field [0002] The invention relates to an artificial board glue, in particular to an artificial board glue capable of reducing the content of human toxic gas and free aldehyde. [0003] (2) Background technology [0004] Conventional wood-based panels mostly use urea-formaldehyde glue, phenolic glue and white latex for wood-based panels. Conventional glue contains formaldehyde, urea, melamine, ammonia, phenol, polyethylene, acid and alkali. There are many harmful gases to the human body. The present invention adds bamboo charcoal and activated carbon to the glue used in the conventional wood-based panels, and adding the bamboo charcoal and activated carbon can more effectively reduce the toxic gas in the glue used in the wood-based panels. [0005] The boom in the real estate market will inevitably lead to a boom in the home improvement market. However, the price of custom-made wood-based panel cabinets dazzles consumers. Behind the huge price differenc...
