It is bigger than AMP-95, the reunion of inorganic pigment can be prevented under steric hindrance effect；The multifunctional assistant introduces Cl, has
Bactericidal bacteriostasis.
The preparation method of the alcamines multifunctional assistant, comprises the following steps：
S1,120-150 part diethanol amine is placed in container, addition while stirring at room temperature has been dissolved with solvent
30-45 part paraformaldehydes, react 0.5-1h；
S2, added into container and use 0.5-1 parts catalyst and 30-50 part hydrochloric acid, react 1-2 hour at room temperature, so
Afterwards plus water stirs 10-30 minutes, obtains clear viscous alcamines multifunctional assistant.
Its synthetic route is as follows：
In one of the embodiments, the step S1 is：It is in liquid that diethanol amine is put into 90 DEG C of bakingizations in baking oven,
Then 120-150 part diethanol amine is placed in three-necked flask, at room temperature mechanical agitation, adds isopropanol dissolving while stirring
Good 30-45g paraformaldehydes, react 0.5-1h.
In one of the embodiments, catalyst described in step S2 is sodium borohydride.
Application of the alcamines multifunctional assistant as pH adjusting agent among coating system.
Application of the alcamines multifunctional assistant as bactericide among coating system.
In one of the embodiments, the coating system is water-proof acrylic acid paint system.
The beneficial effects of the present invention are：The present invention is prepared for a kind of alcamines multifunctional assistant, the more work(of alcamines
Energy auxiliary agent is similar with pH adjusting agent AMP-95 structures, has preferable pH adjustment effects；Compared to AMP-95, the alcamines is more
The more alcoholic extract hydroxyl groups of function additive, substantially increase the suction-operated to inorganic pigment, its surface is become positively charged lotus, quiet
Inorganic pigment solution flocks can be made in the presence of electric repulsion, and its structure is in umbrella, it is bigger than AMP-95, therefore steric hindrance effect ratio
AMP-95 is big, and the reunion of inorganic pigment can be prevented under steric hindrance effect, make inorganic pigment it is uniform and stable be dispersed in painting
In material system；Alcamines multifunctional assistant of the present invention contains Cl, has bactericidal bacteriostasis, can be applied to as antiseptic
In coating system；The preparation method that the present invention prepares the alcamines multifunctional assistant is simple, and time-consuming short, reaction stability is good,
Low raw-material cost, suitable for commercial Application.
