Method for manufacturing biodegradable hot melt adhesive

Abstract

A method for manufacturing a biodegradable hot melt adhesive includes: mixing multiple biodegradable materials and carrying out a chemical cross-linking reaction to form a copolymer; subjecting the copolymer to a hydrolysis reaction to form a hydrolyzed copolymer; and mixing and heating the hydrolyzed copolymer, a first additive, and a second additive, to form the biodegradable hot melt adhesive. The multiple biodegradable materials include at least two of polylactide acid, polycaprolactone, polybutylene succinate, polyhydroxyalkanoates, and polyethylene glycol. The first additive includes at least one of a tackifying resin and a plasticizer. The second additive includes at least one of an antioxidant and a hydrolysis stabilizer. The method for manufacturing the biodegradable hot melt adhesive has the advantages of a simple production process and a low cost, and the manufactured biodegradable hot melt adhesive has excellent performance.
