Measure percentage and stir 15 minutes or so at ambient temperature, in a kettle. to uniform, reaction for 0.01~0.05% catalyst
The rotating speed of mixer is 60 ~ 120 revs/min in kettle；
（2）Reactor heater is then turned on, temperature 70 DEG C of beginning timing are promoted to, and maintain the temperature at 70 ~ 75
Under conditions of DEG C, at the uniform velocity stir and uniform mixed liquor is made within 60 ~ 80 minutes, the mixing speed of mixer is 60 ~ 120 revs/min；
（3）It is 13.5 ~ 23.5% solvents that percentage by weight is finally added in mixed liquor, and mixed liquor is diluted to suitably
Range of viscosities, and be well mixed, monocomponent adhesive is made.
Described adhesive is the adhesive of hydroxyl, specially hydroxy radical content 0.1%, solids content 15~20%, viscosity
One or more in 300~500mpa.s/25 DEG C of adhesive products are combined, and such as nine yuan of Shanghai company's trade mark is

Described curing agent is polyurethane curing agent, specially NCO content 8.5~13.5%, solids content 25~
One kind in 75% isocyanate-terminated polyurethane special curing agent, the trade mark of such as nine yuan of production in Shanghai is JYL-20, JYL-
33 product.
Described catalyst is organic tin catalyst, specially dibutyl tin dilaurate, is the market universal product, board
Number be T12, such as connection scape chemistry T12 products.
Described solvent is that one or more esters combined in ethyl acetate, methyl acetate or dimethyl carbonate are molten
Agent, solvent is the market universal product, and selection moisture is less than 0.03% high-class product.
The present invention compared with the existing technology, has prepared steady quality with simplest process conditions, and cost is lower and energy
Meet the monocomponent adhesive of the different field requirement such as automobile, household, compound, raw material range of choice is cheap easy than wide
, quality control is easy；Production process control is simple, and energy consumption is lower；Production process is more environmentally-friendly.
