[0016] The preparation method of the universal glue stick provided by the present invention includes the following raw materials in parts by mass:
[0017] 25-40 parts of propylene glycol methyl ether; 25-35 parts of acetone; 30-50 parts of absolute ethanol; 2-8 parts of synthetic rubber; 3-10 parts of resin; 10-20 parts of elastomer; 1-5 parts of cosolvent; dispersion 1-3 parts of agent; 5-10 parts of hardening excipient;
[0018] The preparation method is as follows:
[0019] Add propylene glycol methyl ether, acetone, and absolute ethanol to the reaction kettle, turn on the stirring, stir evenly, while stirring, add synthetic rubber, resin and elastomer in sequence to dissolve for 6-12 hours. After the dissolution is complete, turn on the condensing reflux device. Stir and heat up, add co-solvents, dispersants, and hardening excipients while stirring, heat up to 85-90℃, control the temperature at 85-90℃, stir and disperse strongly for 20-30 hours, so that all solid materials are ...
