Abstract

The invention provides a rubber band glue for machines and a preparation method thereof. The rubber band glue for machines comprises the following raw materials in mass percentages: α-cyanoacrylate 84-95%, thickener 4-15%, Accelerator 0.02‑1%. The present invention also provides a preparation method of the rubber band glue for machines, comprising the steps of: adding an accelerator to the α-cyanoacrylate, stirring evenly at room temperature, adding a thickener, and stirring evenly. The rubber band glue of the present invention has good toughness and high bonding strength. After being used for bonding rubber bands, the joint has good toughness, the glue layer is transparent, there is no whitening phenomenon, it is not easy to break, the bonding speed is fast and the stability is good. Does not thicken throughout the line and does not affect 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...
