Said softening agent is one or more the mixture in Witcizer 300, DOP, the neopentyl glycol diisobutyrate.
The preparation method of above-mentioned a kind of self-closing polymer cement waterproof paint comprises the steps:
(1), water, wetting agent, softening agent, silicone antifoam agent are added in the stirring tank successively stirred 30 fens
Clock adds polymer emulsion then and stirs, and promptly gets polymeric constituent, is called for short liquid material component.
(2), cement, silica powder, filler, active masterbatch FLW are put into the powder stirrer successively and fully mix, promptly get the mineral compound component, be called for short the powder component.
Above-mentioned a kind of self-closing polymer cement waterproof paint in use,
PressWeight ratio is calculated, and liquid material component and powder component are pressed 1:1 proportioning mixing and stirring, knife-coat application.Warp is according to GB/T 23445-2009 " polymer cement waterproof paint " standard detection, and tensile strength is 2.22MPa, and elongation at break is 105%, and dereism is 7 hours.
Beneficial effect of the present invention
A kind of self-closing polymer cement waterproof paint of the present invention; Owing to contain the active masterbatch compound of high dispersing; After liquid material and powder two components are mixing cured; This active compound runs into the moisture that infiltrates in the crack and can react with it and form the solid crystal thing, and this solid crystal thing can fuse with interaction such as cement in the waterproof coating and polymkeric substance again, thereby reaches the fissured self-closing n. effect of filming.
Simultaneously, because the polymer emulsion in the waterproof paint can guarantee higher tension set, thereby make its elasticity be superior to the inflexible cement group water-proofing material greatly.
And owing to contain polymer emulsion in the waterproof paint, the construction gel time of made waterproof paint is also much larger than cement group water-proofing material, but so knife-coat application.
