Description

Technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-efficiency environmentally friendly adhesive and plywood. Background technique [0002] Adhesives include organic adhesives and inorganic adhesives. Organic adhesives mainly include silicone resin, silicone rubber, polyimide, phenolic, epoxy resin, etc., while inorganic adhesives mainly include silicate Type, alkali metal phosphates and silica sol. There are many types of organic adhesives, and the bonding strength of materials is generally high. For example, epoxy adhesives are called universal adhesives, which have many varieties and are widely used. Phenolic resins are the earliest industrialized synthetic resins. Due to the advantages of high bonding strength and high carbon residue, due to the incompatibility between organic and inorganic materials, organic adhesives are usually used for bonding of organic materials, while inorganic adhesives are mostly used for bonding...
