This masterbatch acting as in this cement based penetration crystallization type water proofing paint is penetrated in the cement matrix, meets water generates stable crystalline body, stops up aquaporin; Accelerate the speed of cement concrete internal crystallization regeneration; Reduce the base material reaction, make in the concrete alkali content because of using admixture not raise.
Embodiment seven: adopt the masterbatch 150kg among the embodiment six, strength grade is the silicate cement 500kg more than 42.5, double-quick cement (world) 80kg, acid resistance 60～80 purpose silica sand 270kg; After above-mentioned all material stirred 50 minutes, emit stirrer bottom material 50kg after, again this is emitted the 50kg bed material and drops into stirrer and mix blowing can after 20 minutes.
This product is through the check of national building materials Industrial buildings water-proof material product quality supervision and inspection test center, and quality product meets the performance requriements of I type coating among the GB/18445-2001.Test result is following:
| Final set h | The positive and negative 10min of benchmark value | Qualified | ||
| 7 | The finished product folding strength | 3 days, Mpa | Benchmark value positive and negative 0.2 | Qualified |
| 8 | Finished product ultimate compression strength | 3 days, Mpa | Benchmark value positive and negative 0.5 | Qualified |
Use the concrete of this cement based penetration crystallization type water proofing paint can bear the head 4 (3.9Mpa) of 390m, it belongs to typical body water-proof material, has good waterproof effect.The cement based penetration crystallization type water proofing paint that uses the preparation of this masterbatch in the Shanghai World's Fair performing art centre, oriental art center, Shanghai; Xi'an, the Chengdu tunnel of awaiting a subway; Dalian rail rapid transit system, center, transport hub, Hongqiao Airport, railway station, Shanghai, Shanghai Underground 12; Be widely used in No. 13 key state projects such as line, receive the consistent favorable comment of domestic and international expert deeply.
More than water, material during cement based penetration crystallization type water proofing paint mix among each embodiment than being 0.26～0.3, generally get 0.28; The volume that increases yellow soda ash can shorten time of coagulation, but can reduce fluidity of slurry; Can increase fluidity of slurry through increasing the Hydrocerol A volume, prolong time of coagulation; Mixed material should fully stir, and can obtain best application property and water resistance; The maximum particle diameter of silica sand can be regulated according to the purposes of waterproof paint; The ratio of silica sand is adjusted according to the sand grating of being purchased.
More than cement based penetration crystallization type water proofing paint among each embodiment when using, in cement hydration process, bioactive molecule is water-soluble; Under the osmosis of water; Being carrier with water brings the space of coating and basic unit into water, along with pH value descends, under the catalysis of cement (silicate); Active substance is progressively polymerization in the hole of coating and basic unit, in concrete micropore and the insoluble complicated and confused shape crystallization of the full formation of kapillary transmission.The acicular structure that the complicated and confused shape xln that active substance produced is a free-running property, thus concrete intensity can not be improved because of the filling of xln, but, cause xln water insoluble because macromole or high molecular xln contain more hydrophobic grouping.Like this, water-fast xln can strengthen the liquid anti-permeability performance of team of basic unit greatly to the filling of basic unit's defective, and reaches good block-water effect.Simultaneously, the active substance in the masterbatch under the effect of catalyzer, continuous unreacted cement particle and the relatively poor material of crystallization completely in the activation concrete, it takes place hydration in catalysis once more; As long as there is water to exist, it just can constantly play katalysis, makes the further crystallization of silicate material in the concrete, plays waterproof, reinforcement, protection action of steel bars.When anhydrous, activeconstituents keeps stationary state, and when contacting with water, the active substance of coated sealing produces secondary crystal, has the function of automatic reparation crackle at basic unit's fault location after meeting water, and anti-basic unit changing capability is strong; Because the crystallization velocity of the curing speed specific activity material of cement is fast; The active matter of a part is by shutoff not polymerization or only produce oligomeric phenomenon in the cement based coating, in case cracking appears in cement basic layer, under moisture conditions; Active material discharges automatically; Can bring in the crack with water once more, further polymerization produces the passage of stable xln with shutoff water, and water resistance increases in time and strengthens.
Use the impervious pressure of the basic units such as lean concrete grout sand-cement slurry and concrete of above-mentioned cement based penetration crystallization type water proofing paint to strengthen 200-500 doubly, prolong work-ing life, can not reduce intensity, has permanent effect.
