ねじ部材用接着剤組成物、接着剤組成物の製造方法および接着剤組成物を用いた固定構造
Document Type and Number:
Japanese Patent JP6949676
Kind Code:
B2
Abstract:
To provide an adhesive composition faster in drying time than an aqueous solvent, using ethanol lower in toxicity than methanol, and capable of using a vinyl acetate polymer large in cohesive energy of polymers each other and high in polymerization degree as an adhesive component, a manufacturing method of the adhesive composition and a fixing structure using the adhesive composition.SOLUTION: There is provided an adhesive composition for screw member containing 25 to 35 mass% of a vinyl acetate polymer and 65 to 75 mass% of ethanol, in which the vinyl acetate polymer consists of a vinyl acetate polymer with polymerization degree of 300 to 800 and a vinyl acetate polymer with polymerization degree of 1200 to 1300.SELECTED DRAWING: Figure 1
