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 a kind of functional polymer cement waterproof paint after its film is ftractureed by External Force Acting with self-enclosed (self-healing) performance.Its representative products is the PARATEX of Japanese high point Chemical Co., Ltd. invention.At present domestic more existing enterprises successfully develop related products (referring to ZL201010137870.5, ZL201110225371.6) and start to promote the use of.Its healing mechanism is generally the leak stopping healing by the generation of water penetrant crystalline thing.Dereism is with the time representation of film crack self-enclosed (self-healing) under prescribed condition.In order to adapt to the selfreparing requirement that waterproofing work is higher, reach better practical function (shortening the self-healing time) and often need to add active substance improve dereism.But the construction effect of self-closing polymer cement waterproof paint is usually not fully up to expectations in practical engineering application, mainly because rapid solidification after the adding two components that membership causes coating and mix of active substance shortens the engineering time and coating is difficult to Self-leveling, if the self-closing of the application unit (selfreparing) polymer cement waterproof paint product (referring to ZL201110225371.6) is when active masterbatch accounts for powder part by weight while being 4%, dereism is 7 hours
presetting period is 40 minutes,coating solidification time and engineering time match substantially; In the time that active masterbatch accounts for powder part by weight and is 7% left and right, dereism is 4 hours,
presetting period is 15 minutes,be that selfreparing effect improves greatly, cause the coating can not Self-leveling but the coating solidification time has not matched with the engineering time.As made the mechanical property of film be greatly affected by adding big yield to increase setting time; As adopting, water-holding agent adds and causes a series of degradation of film and poor effect because the large need of its molar mass are a large amount of as acrylamide-acrylicacid salt crosslinking copolymerization thing, starch grafted acrylate crosslinking copolymerization thing etc.As added the self-closing polymer cement waterproof paint of acrylamide-acrylicacid salt crosslinking copolymerization thing or starch grafted acrylate crosslinking copolymerization thing, its cohesive strength is less than 0.6MPa.
Summary of the invention
The object of the invention is to provide in order to solve above-mentioned technical problem a kind of
there is good application property self-closing polymer cement waterproof paint, this self-closing polymer cement waterproof paint can reach compared with long setting time and cause coating Self-leveling and have good dereism (self-healing) simultaneously, become a kind of self-closing polymer cement waterproof paint with good application property, and other property retention is good.
Technical scheme of the present invention
A kind of self-closing polymer cement waterproof paint, is made up of powder and liquid material, by weight calculating, and powder: liquid material is 1:1;
Wherein said powder, calculates by weight, and its composition and content are as follows:
45 parts of cement
45 parts of silica powders
40 parts of fillers
10 parts of active masterbatch FLW
Described liquid material, calculates by weight, and its composition and content are as follows:
90 parts of acrylic ester emulsions
065 0.5 parts of wetting agent SILCO WET
5 parts of neopentyl glycol diisobutyrates
0.5 part of silicone antifoam agent
0.5～0.8 part of water-holding agent
20 parts, water;
Described water-holding agent is alkyl biphenyl base ether sulfonate, fatty alcohol polyoxyethylene ether sulfate or alkyl phenol ether sulfosuccinate ester salt.
The preparation method of above-mentioned a kind of self-closing polymer cement waterproof paint, step is as follows:
First, each component of powder is mixed, obtain powders mixture;
Then, each component of liquid material is mixed, obtain liquid material mixture;
Finally, powders mixture and liquid material mixture are mixed by weight the ratio of 1:1, obtain self-closing polymer cement waterproof paint.
beneficial effect of the present invention
of the present inventiona kind of self-closing polymer cement waterproof paint, due to
the water-holding agent that contains high dispersing, this water-holding agent shouldself-closing polymer cement waterproof paint
in the rapid emulsification of moisture and produce cement-emulsified micella, this emulsification micella can slow down the interaction of cement and water and the setting time that extends film.Because the existence of water-holding agent can keep containing more not hydrated cement in film, in the time that film produces crack infiltration, more generation silicate crystallisate is strengthened to dereism simultaneously.
further, a kind of self-closing of the present inventionpolymer cement
the setting time of waterproof paint detects according to GB/T1346-2011 " cement normal consistency water consumption, time of coagulation, the stability method of inspection " standard, shouldself-closing polymer cement waterproof
the presetting period of coating is greater than 45 minutes; The dereism of its film detects according to GB/T 23445-2009 " polymer cement waterproof paint " standard, and dereism is 4 hours.
show thus self-closing of the present inventionpolymer cement
waterproof paint had both had good selfreparing effect, possessed again enough construction operation times, had ensured working security.Andafter film, have good adhesive property, its cohesive strength is 0.7Mpa.
