In mixing container, start high speed shear stirrer, continuously stirring 2 ~ 3 hours under the speed conditions of 400～600 revs/min;
In stirring, fluid temperature is elevated to 30～40 DEG C, and creating pockets of air, then stops stirring, and through filtration treatment, obtains described ultrasonic sealing polyurethane adhesive.
In technique scheme, further improved plan is as follows:
1, in such scheme, the solid content of described ultrasonic sealing polyurethane adhesive is 50%, and viscosity is 1200 cps.
2, in such scheme, described in mixing container stirrer rotating speed be 600 revs/min.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
Ultrasonic sealing polyurethane adhesive of the present invention, its mechanism of action be base polyurethane prepolymer for use as under ul-trasonic irradiation, curing cross-linked and form stable chemical structure.It is the material of pure solid, does not need in use to add any solvent; Production efficiency is high, simple through ultrasonic hot composition operation technique when use; Have extremely strong perviousness and avidity, bond strength exceeds 40%～60% than other tackiness agent under similarity condition; Good weatherability has possessed irreversible characteristic, thereby can not be subject to variation of ambient temperature and produce creep and embrittlement after building bridge.The excellent propertys such as water-fast steam, chemicals-resistant and resistance to solvent.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
Embodiment: a kind of ultrasonic sealing polyurethane adhesive, the formula of described ultrasonic sealing polyurethane adhesive is made up of following parts by weight of component:
7,415 58 parts of urethane resin Bostick,
