Abstract

The invention discloses an efficient dehumidification adhesive for plywood. The efficient dehumidification adhesive for plywood is composed of, by weight, 50-100 parts of attapulgite powder, 10-20 parts of calcium bentonite, 10-15 parts of nanosilicon dioxide, 15-30 parts of nanometer magnesia, 15-30 parts of super absorbent resin, 10-15 parts of anhydrous calcium chloride, 5-10 parts of wheat flour, 5-10 parts of sodium hydroxide and 10-15 parts of carboxymethyl cellulose. The raw materials for preparation of the adhesive are all natural mineral resources and inorganic salt which are easy to obtain, and the raw materials are low in price, nontoxic and environmentally friendly. The adhesive can increase the surface contact area between resin and the plywood, has the effects of efficient dehumidification and drying, and has the advantages of high bonding strength and long service life.

Description

technical field [0001] The invention relates to a high-efficiency dehumidifying adhesive for plywood, which belongs to the technical field of drying. Background technique [0002] Desiccants refer to substances that can remove moisture from wet substances, such as calcium sulfate and calcium chloride, and dry by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, dry by physically adsorbing water. Moisture control is closely related to product yield. For food, under proper temperature and humidity, bacteria and mold in food will multiply at an alarming rate, causing food to rot, causing dampness and discoloration. Change. Electronic products can also cause metal oxidation due to high humidity, resulting in defects. The use of desiccant is to avoid the occurrence of defective products caused by excess moisture. Many home improvement panels used to use a large amount of glue, and the dehumidification effect is poor, the dryi...
