Abstract

The invention provides machine rubber band glue and a preparation method of the rubber band glue, and the rubber band glue for a machine is prepared from the following raw materials in percentage by mass: 84-95% of alpha-cyanoacrylate, 4-15% of a thickening agent and 0.02-1% of an accelerant. The invention also provides a preparation method of the rubber band glue for the machine, which comprisesthe following steps: adding the accelerator into alpha-cyanoacrylate, conducting uniform stirring at room temperature, adding the thickening agent, and conducting uniform stirring to obtain the rubberband glue. The rubber band glue has good toughness and high bonding strength, and after the rubber band glue is used for bonding rubber bands, joints are good in toughness, transparent in glue layer,free of whitening phenomenon, not prone to breakage, high in bonding speed and good in stability, and the glue cannot be thickened in the whole assembly line work and does not influence bonding.

Description

technical field [0001] The invention relates to a rubber band glue for machines and a preparation method thereof, belonging to the technical field of adhesives. Background technique [0002] Rubber band is a short loop made of rubber and latex. It has the advantages of high elongation, good resilience, low price, and convenient use. It has a large application market. Rubber bands need to be bonded with adhesives during production. At present, rubber bands need to be bonded manually, but more and more factories use machines to process rubber bands. Manual adhesives are not suitable for machine production. Manual adhesives When bonding rubber bands, the general operation time is 4 to 5 seconds, while the operation time required for machine rubber band glue is generally only about 2 seconds. Therefore, the bonding speed of manual adhesives is relatively slow, and it is not suitable for machine bonding rubber. Ribs, and the glue cannot thicken during the entire assembly line pr...
