As can be seen from Table 14: finished product paint-like state is poor in embodiment 9 in the system, particle is not full, and application property is poor, freezes
It is poor to melt stability；Finished product paint-like state is good in embodiment 10,11,12,13, application property is preferable, but freeze thawing is poor: embodiment
14, the freeze thawing of finished product paint is preferable in 15, but application property is general.Finished product paint is in the best state in embodiment 16, and freeze-thaw stability is excellent,
Application property is good.
In conclusion it is preferred that dispersed phase main choosing of the RS-6733 lotion as the Northwest's multicolor finish: preferred GS/GTS body
System selects protective glue system as main, the selection of cellulose based on 250HBR or HS30000 class, HE3KB containing hydrophobic function and
HE10KB is unfavorable to the freeze-thaw stability of system；For dispersing agent, hydrophobic sodium polycarboxylate dipersant is comprehensive in colorful system
It closes performance and is not so good as polycarboxylic acid ammonium salt dispersant.Under equal conditions, the increase of dispersing agent and kaolin amount will affect the freeze thawing of system
Stability.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
