Abstract

The invention discloses a low-cost high-strength flame-retardant smoke-suppressing artificial board inorganic adhesive and a preparation method thereof. The low-cost high-strength flame-retardant smoke-suppressing artificial board inorganic adhesive comprises the following components in parts by weight: 30-50 parts of magnesium oxide, 20-40 parts of magnesium chloride, 30-60 parts of water, 3-8 parts of polyvinyl alcohol, 1-5 parts of trisodium phosphate, 2-7 parts of water glass, 0.08-0.1 part of tartaric acid, 0.5-3 parts of sulfonic acid, 0.05-0.3 part of octylphenol polyvinyl ether and 0.01-0.2 part of sodium carboxymethyl cellulose. The low-cost high-strength flame-retardant smoke-suppressing artificial board inorganic adhesive prepared through the method is noninflammable and achieves outstanding flame-retardant smoke-suppressing property on an artificial board. The fire-proof grade of the prepared artificial board achieves A2 grade through testing; the price of the prepared artificial board only accounts for 5% of the price of an isocyanate adhesive and accounts for 50% of the price of an urea-formaldehyde resin adhesive; the internal bonding strength of the produced artificial board achieves 1.05 MPa, the static bending intensity achieves 16.5 MPa, and the 24-hour water absorption thickness expansion ratio is only 1.1%. The low-cost high-strength flame-retardant smoke-suppressing artificial board inorganic adhesive disclosed by the invention can not release any harmful gas and achieves outstanding environmental-friendly property.

Description

technical field [0001] The invention relates to the field of wood-based panel adhesives, in particular to a low-cost, high-strength, flame-retardant, smoke-suppressing, wood-based panel inorganic adhesive and a preparation method thereof. Background technique [0002] my country is short of wood resources. The wood-based panels produced by using fast-growing wood, branch wood and crop straw can replace wood and be used in furniture manufacturing, indoor and outdoor decoration and other fields. The development of the wood-based panel industry is of great significance to the protection of my country's forest resources. The adhesive used in the production of wood-based panels is usually urea-formaldehyde resin adhesive, which will release free formaldehyde during production and use, which will bring great harm to human health. Straw-based panels usually use isocyanate adhesives. Because isocyanate adhesives are expensive, the cost of manufacturing crop-based panels is extre...
