Embodiment 1
[0029] An adhesive used for bonding cables, mainly comprising:
[0030] 15 parts of modified aldehyde and ketone resin, 10 parts of polyurethane, 4 parts of sodium alginate, 1.5 parts of phenolic lignin, 1 part of filler, and 1 part of curing agent.
[0031] A preparation method of an adhesive for bonding between cables, the preparation method of the adhesive for bonding between cables is:
[0032] (1) Mix formaldehyde and cyclohexanone in a three-necked flask at a mass ratio of 1:3.7, heat it in a water bath to 80°C, and add 0.15 times the mass fraction of formaldehyde with 10% sodium hydroxide solution dropwise at 5 drops / min , after reacting for 1 hour, cool to room temperature, add isopropanone with 0.3 times the mass of formaldehyde and deionized water with 0.2 times the mass of formaldehyde, stir at 800rpm and heat up to 80°C, add sodium alkylbenzenesulfonate with 0.1 times the mass of formaldehyde, wait After there is no solid in the three-necked flask, add a mixture o...
