Description
Technical field
The present invention relates to a kind of self-closing polymer cement waterproof paint.
Background technology
Self-closing's (self-healing) polymer cement waterproof paint is to have self-enclosed (oneself by External Force Acting after its film is ftractureed
Healing) a kind of functional polymer cement waterproof paint of performance.Its representative products is the invention of high point Chemical Co., Ltd. of Japan
PARATEX.Current domestic more existing enterprises successfully develop Related product (see ZL201010137870.5,
And start to promote the use of ZL201110225371.6).The generally leak stopping by the generation of water penetration crystal of its healing mechanism
Healing.Dereism is with the time representation of film crack under rated condition self-enclosed (self-healing).Higher in order to adapt to waterproofing work
Selfreparing requirement, reach more preferable practical function (i.e. shorten self-healing time) and generally require interpolation active substance improve from
Closing property.But in practical engineering application, the construction effect of self-closing polymer cement waterproof paint is the most not fully up to expectations, mainly
It is to shorten the engineering time and coating is difficult to due to the adding rapid solidification after membership causes two components mixing of coating of active substance
Self-leveling, self-closing's (selfreparing) the polymer cement waterproof paint product such as the application unit (sees
ZL201110225371.6) when activity masterbatch account for powder part by weight be 4% time, dereism is 7 hours, and the presetting period is 40 points
Clock, the coating solidification time matches substantially with the engineering time；When activity masterbatch account for powder part by weight be about 7% time, dereism
Being 4 hours, the presetting period is 15 minutes, i.e. selfreparing effect is greatly improved, but the coating solidification time with engineering time not phase
Coupling and cause the coating can not Self-leveling.As by add big yield with increase setting time the mechanical property of film then can be made to be subject to
The biggest impact；Water-retaining agent such as acrylamide and acrylic acid salt crosslinking copolymerization thing, starch grafted acrylate copolymerization as used
Cross-linking agents etc. then cause a series of hydraulic performance decline of film and poor effect owing to the big need of its molal weight add in a large number.As added
The self-closing polymer cement of acrylamide and acrylic acid salt crosslinking copolymerization thing or starch grafted acrylate crosslinking copolymerization thing is prevented
Water paint, its adhesion strength is less than 0.6MPa.
Summary of the invention
The invention aims to solve above-mentioned technical problem and provide a kind ofThere is good application propertySelf-closing
Polymer cement waterproof paint, this self-closing polymer cement waterproof paint can reach longer setting time and cause coating certainly
Levelling and simultaneously have preferable dereism (self-healing), becomes a kind of self-closing polymer cement with good application property
Water-repellent paint, and other property retention is good.
