Aldehyde-free liquid glue and artificial board processing method

The invention relates to aldehyde-free liquid glue and an artificial board processing method. The liquid glue is prepared by mixing and blending an magnesium chloride aqueous solution and magnesium oxide powder, serving as inorganic materials, according to the ratio of 1: 1; the magnesium chloride aqueous solution is prepared from magnesium chloride powder or halogen pieces and water according to the ratio of 1: 1 to 1: 3, and the purity of the magnesium chloride powder or the halogen pieces is 45% to 99%. Therefore, the liquid glue does not contain formaldehyde, also has favorable gluing strength, is low in price and can also be directly applied to existing mechanical equipment to process artificial boards, without adding or transforming original mechanical equipment, and also without changing an operation mode of longtime habit. The liquid glue is easily accepted by artificial board manufacturers, high in market competitiveness and easily promoted and sold; in addition, when the liquid glue is used for manufacturing the artificial boards, the artificial boards can be directly subjected to hot pressing after coated with the aldehyde-free liquid glue, without undergoing cold pressing, so that the processing procedures are simplified, the production efficiency is high, and meanwhile, the hot pressing temperature is relatively low, the energy consumption is reduced and the production cost is lower.
