SELF-HEATING INORGANIC ADHESIVE, PREPARATION METHOD THEREOF AND APPLICATION METHOD THEREOF IN PRODUCTION OF INORGANIC WOOD-BASED PANEL

摘要

The invention discloses a self-heating inorganic adhesive. The self-heating inorganic adhesive comprises two components and concretely comprises an inorganic adhesive semi-finished product and a quicklime gelatin capsule in a weight ratio of (40-60): (10-25). The inorganic adhesive semi-finished product is prepared from 30-60 parts by weight of water, 20-30 parts by weight of aluminum hydroxide, 20-35 parts by weight of phosphoric acid, 10-20 parts by weight of calcium sulfate, 4-10 parts by weight of fly ash, 3-5 parts by weight of calcium carbonate, 2-4 parts by weight cooked glutinous riceflour and 0.3-0.7 parts by weight of curcumin. The invention also discloses a preparation method of the self-heating inorganic adhesive. Through use of the cooked glutinous rice flour as the initial adhesive, the initial viscosity of the adhesive is effectively increased. Through use of the inorganic adhesive in the production of agricultural and forestry residual fiber (planing) boards, the problems of loosing in the board blank transportation and loading and unloading are solved. Compared with other initial adhesives, the cooked glutinous rice flour has obvious price advantages.
