Abstract
The present invention discloses a cement base osmotic crystallizing waterproof material and the producing process thereof. The present invention comprises the following components in weight percent: 35% to 55% of portland cement, 5% to 20% of calcium carbonate, 25% to 50% of silca sand, 1% to 5% of osmotic crystallizing active master batch, 0.05% to 0.2% of methyl cellulose MHEC15000PFR, 0.05% to 0.2% of methyl cellulose MHEC20000PFR, 4330-3 0 to 2.5% of BaiErLe and 1 to 4% of encrypted microsilicon. The present invention has the successive production processes of screening, mixing, feeding, blending, checking and packaging and storing. The waterproof material forms crystallizing waterproof protective layers in micropores of the cement base to stop the exudation of water; the present invention has the advantages of water resistance, permanent moisture-resistant effect, stable performance and high intensity, and has strong adhesive force with the surface of concrete poured in advance.
Description
Technical field
The present invention relates to a kind of construction work material, more specifically to a kind of flat, the facade waterproof of concrete structure building, the cementitious capillary waterproofing material and production technique thereof of antiseep of being used for.
Background technology
In construction work, many buildingss all have the requirement of water leakage, as exterior wall of underground garage room, tunnel, culvert, swimming pool, treatment tank, buildings etc.And the poor-performing of the cement impervious waterproof of normal concrete, water can be by the micropore permeation of normal concrete cement.In general construction, adopt for this reason and isolate the water source with the coiled material or the coating of waterproof at the upstream face or the back side of normal concrete, this construction complexity, waterproof effect is difficult for guaranteeing.There are patent disclosure (bulletin) number CN1587173 and CN1472258 to introduce cementitious capillary waterproofing material and production technique and constructional method and cementitious capillary waterproofing material for building and preparation method thereof respectively recently, this water-proof material mixes the back brushing mostly and directly removes the concrete surface of newly building on concrete surface or with dry powder form with water, this waterproof effect instability is for the relatively difficulty of just filling up of the existing crackle of concrete surface.
Summary of the invention
The present invention has overcome deficiency of the prior art, provides a kind of impervious good water-proof effect and existing prescription and using method that cementitious capillary waterproofing material and production technique thereof than big-difference are arranged.
Cementitious capillary waterproofing material of the present invention and production technique thereof is characterized in that comprising by weight percentage following component: ordinary Portland cement 35-55%, lime carbonate 5-20%, silica sand 25-50%, the active masterbatch 1-7% of penetrant crystalline, methylcellulose gum MHEC15000PFR 0.05-0.2%, methylcellulose gum MHPC20000PFR 0.05-0.2%, the happy 4330-3 0-2.5% of Bayer, the little silicon 1-4% of encryption.
The production technique of cementitious capillary waterproofing material is successively: screening: oarse-grained raw material is removed by sieve; Batching: according to above-mentioned prescription batching; Feeding: each raw material is transported to stirrer; Spice: raw material stirring is even by stirrer; Check: physics and the chemical property of checking compound; Packing warehouse-in: will put in storage after qualified cementitious capillary waterproofing material pack or the tinning.
The cementitious capillary waterproofing material of Zhi Zaoing according to the method described above; in use can be as ordinary Portland cement; add that water stirs; be coated with and scrape at the very thin one deck of concrete surface; can also fill up pit, crackle that concrete produces in constructing in earlier stage; this water-proof material forms the crystalline fish tail and waterproof layer in the micropore of cement based; oozing out of blocking-up water; waterproof, moisture resistance effect are permanent; the former concrete of its antiosmotic pressure force rate increases 200-500 doubly; with the concrete surface strong adhesion of building in advance, stable performance, intensity height.Except waterproof, this material can also be as on the container or buildings of blocking other fluid seepage.Certainly also can be as existing cementitious capillary waterproofing material, play waterproof effect as the coating brushing on concrete surface after adding water.
Embodiment
The invention will be further described below in conjunction with embodiment.
Cementitious capillary waterproofing material of the present invention comprises following component by weight percentage: ordinary Portland cement 35-55%, lime carbonate 5-20%, silica sand 25-50%, the active masterbatch 1-7% of penetrant crystalline, methylcellulose gum MHEC15000PFR 0.05-0.2%, methylcellulose gum MHPC20000PFR 0.05-0.2%, the happy 4330-30-2.5% of Bayer, the little silicon 1-4% of encryption.
