Organic-inorganic modified adhesive and preparation method thereof

The invention relates to an organic-inorganic modified adhesive and a preparation method thereof. The modified adhesive is formed by mixing an inorganic ternary system material, organic macromolecule resin and a modifying agent, and the modified adhesive comprises, in percentage by weight, 0-3% of the modifying agent and the balance of the inorganic ternary system material and the organic macromolecule resin with the weight ratio being (5-95):(95-5). Thus, the prepared organic-inorganic modified adhesive is formaldehyde-free, high in bonding strength, very low in price and capable of being directly applied to existing mechanical equipment for machining of artificial boards, no existing mechanical equipment is required to be added or transformed, no operating mode is required to be changed, and the modified adhesive is easily acceptable to manufacturers and easy to promote and sell; products with different cold-press effects and different bonding strength can be prepared through adjustment of the ratio of the inorganic ternary system material to the organic macromolecule resin, and the modified adhesive is applicable to machining of different artificial boards.
