Table 2
As can be seen from Table 1, water-repellent paint prepared by the present invention is more tolerant to execution conditions, at 35 ± 2 DEG C of maximum temperature,
Still there is good coating result under humidity (65 ± 5) %, and comparative example is at 32 ± 2 DEG C, the lower coating formed of humidity 60 ± 5% is
There are a small amount of particle and bubble to generate, as the time is elongated, the coating stability, heat-resisting of particle, bubble occurs in environmental degradation
Property, weatherability are deteriorated, to affect waterproof effect.
As can be seen from Table 2, water-repellent paint heat resistance and stability prepared by the present invention exist with comparative example, the present invention by force
Temperature 55(± 2) DEG C, store 15 days, viscosity be still maintained at 20Pa.s hereinafter, and coating still uniformly without precipitating, it is comprehensive
Performance is high, and comparative example is in 45(± 2) DEG C, storage has had slight deposited phenomenon in 15 days, when temperature becomes 55(± 2) DEG C, storage
When depositing 15 days, viscosity alreadys exceed 20Pa.s, and comprehensive performance starts to be deteriorated, and coating starts to occur precipitating and be layered now
As stability and heat resistance are worse than the present invention.
In order to embody beneficial effects of the present invention to the greatest extent, the present invention should take under type such as to construct:
1, exterior wall wall tile waterproof: basal plane thoroughly cleans, is dry, it is oil-free it is dustless, mend a split and eliminate voids and pits, using craft
It brushes or is sprayed using high pressure fog, to be impregnated with comprehensive degree of being covered as.
2, cement-base concrete: swimming pool, base surface want closely knit secured, dry；At uneven and crack, needs to criticize and scrape
Water-proof putty, it is general when brushing 2-3 all over, brushing it is noted that it is previous all over coating it is solid it is tack-free after apply again latter time, and apply
Brushing direction should be criss-cross (note: a direction brush cannot carry out backwash)；Interval time between each layer is solid with previous coating film
Subject to not viscous, the maximum overlay painting interval time be must not exceed 36 hours；The seam crossing of material is directly coated with；Such as overcast and rainy tide
Wet environment should not then construct.
3, after construction of waterproof layer, the various pieces of entire engineering, especially outdoor tile gap should conscientiously be checked more
It conscientiously to check, coating should not have phenomena such as leakage brush, layering, alice, crackle.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is not considered as limiting the invention, those skilled in the art are not departing from the principle of the present invention and objective
In the case where can make changes, modifications, alterations, and variations to the above described embodiments within the scope of the invention.
