(2) being placed in agitator tank by starch, add water, stirring 18 minutes, are placed in couveuse clockwise, and regulation temperature is 45 DEG C, and insulation is placed 5 hours；
(3) heat water to 65 DEG C, pour in the reactor with thermometer, be sequentially added into blanc fixe, organobentonite and flyash, stir, be heated to insulation 35 minutes when 108 DEG C, continue to be slowly heated to add benzoic acid when 140 DEG C, insulation reaction 4 hours, is cooled to room temperature；
(4) step (1) products therefrom is joined in step (3) gained reactor, start stirring, acrylic resin and stearic acid are sequentially added in reactor, continue stirring 13 minutes, add sodium hydroxide, regulation pH is 7.4, adds boric acid, acetamide and methylcellulose, high-speed stirred 25 minutes；
(5) being placed in high speed agitator by step (4) products therefrom, add step (2) products therefrom and methyl-silicone oil, (rotating speed is 4900r/min) stirs 60 minutes at a high speed, equilibrium is warming up to 132 DEG C, being incubated 3 hours, it is 5% that vacuum distilling removes water to water content, is down to room temperature, add sodium hydroxide, regulation pH is 7.1, is spray-dried, is rapidly cooled to room temperature at 164 DEG C, cross 260 mesh sieves, encapsulation.
Using method: add water move to the thick shape 30%-40% of building putties quality (consumption of water be), be again stirring for after standing 5-15 minute uniformly can using, criticize routinely with steel scraper plate or spatula and scrape.
Test example:In order to verify the effect of one building putties (embodiment 1-5) of the present invention, we have done contrast test, select cement wall surface, test temperature is 23 ± 2 DEG C, humidity is 50% ± 5%, and experimental group uses one building putties of the present invention, adds water move to the thick shape 30%-40% of building putties quality (consumption of water be), it is again stirring for after standing 5-15 minute uniformly can using, criticizes routinely with steel scraper plate or spatula and scrape；Matched group uses other building putties (purchased from Qingdao Mei Erjia building and ornament materials company limited), measure respectively drying time (surface drying, h) and adhesion strength (MPa), observes initial dry cracking resistance (3h), concrete condition such as table 1:
Table 1
By table 1 it is apparent that, use the experimental group of building putties of the present invention compared with the matched group using other building putties, drying time substantially shortens, the especially drying time of embodiment 5 is only 2.36h, and matched group is up to 4.94h, so the drying time of building putties of the present invention is short more than the drying time of other building putties a lot, improve efficiency of construction.And use the adhesion strength of building putties of the present invention more than the sticking strength height using other building putties.Additionally, use the equal flawless of building putties of the present invention, and use other building putties have crackle.So building putties function admirable of the present invention, initial dry cracking resistance is good, is worth of widely use, and has bigger application prospect.
Finally it should be noted that, embodiment is the detailed description of the invention that the present invention is optimum, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
