High-strength moisture-proof starch glue and preparation method and application method thereof

The invention relates to the technical field of adhesives, particularly to a high-strength moisture-proof starch glue and a preparation method and application method thereof. The high-strength moisture-proof starch glue is composed of the raw materials including, by weight part, 100 parts of corn starch, 4-20 parts of phenolic oligomer, 2-10 parts of polylactic acid, 0.5-3 parts of borax, 0.5-5 parts of nickel sulfate hexahydrate, 2-15 parts of sodium peroxide, 1-5 parts of tributyl phosphate and 200-300 parts of water. The h high-strength moisture-proof starch glue is high in bonding strength in humid environments, product bonding stability and moisture-proofness, has anti-mildew effects and avoids environmental pollution when degraded. The preparation method of the h high-strength moisture-proof starch glue is simple and convenient to apply.
