Abstract
The present invention relates to high-performance water-proof cement and manufacture method thereof.Silicate cement or aluminate cement with high grade are basic raw material, add the water-proofing powder masterbatch of being made up of ground dolomite, zinc stearate, Sodium Silicofluoride, silica flour and wooden calcium sulfonate, form high-performance water-proof cement after stirrer fully mixes.Water-repellent cement of the present invention has advantages such as good water-proof effect, bonding strength height, easy construction, production cost be low.
Description
The present invention relates to cement material for building, particularly high-performance water-proof cement and manufacture method thereof.
Present domestic water-proof material uses organic materials more, as four oily three felts, waterproof roll, resin type waterproof paint etc.Because the organic waterproof material itself has cost height, construction complexity, is subjected to the extraneous thermal effect life-span short, shortcomings such as maintenance cost height, domestic part industry has turned to emerging inorganic waterproof material, as waterproof treasured (being only limited to inner wall waterproofing paint), leak stopping spirit (being limited to local water blockoff), micro-expansion cement, U type swelling agent etc.But above-mentioned inorganic waterproof material still has deficiency, and some is range of application narrow (being only limited to the part), and some is to have given prominence to water resistance, but has reduced the performance of cement self.
The objective of the invention is to overcome the defective that exists in the prior art, a kind of water-repellent cement material and manufacture method thereof with dynamical water-repellancy and high-intensity bonding effect is provided.
Another object of the present invention provides a kind of water-repellent cement that is widely used in the various construction works of waterproof requirement, also can be used to produce the cement prefab of different shape.
A further object of the invention provides simple, the lower-cost high-performance water-proof cement of a kind of production technique, but this water-repellent cement acid-and base-resisting, do not chap, do not expand, non-warping, very strong sticking power is arranged.
Technical solution of the present invention is as follows:
A kind of high-performance water-proof cement, its composition comprises: a, cement base-material 95-97%(weight percent, as follows); B, water-proofing powder masterbatch, its composition is: ground dolomite 2.1-3.5%, zinc stearate 0.28-0.47%, Sodium Silicofluoride 0.36-0.6%, silica flour 0.02-0.03%, the 0.24-0.4% of wooden calcium sulfonate.Described cement is silicate cement or aluminate cement.Described cement is 525 high strength cements.The fineness of described ground dolomite is between 120 order to 200 orders, and the fineness of zinc stearate, Sodium Silicofluoride and silica flour is more than 300 orders, and the fineness of wooden calcium sulfonate is more than 200 orders.Described ground dolomite is 2.5%, and zinc stearate is 0.34%, and Sodium Silicofluoride is 0.44%, and silica flour is 0.03%, and wooden calcium sulfonate is 0.29%, and described 525 silicate cements are 96.4%.The method of the manufacturing of high-performance water-proof cement may further comprise the steps successively; A, be ground dolomite between 120 order to 200 orders with fineness, fineness is that zinc stearate, Sodium Silicofluoride, silica flour and the fineness more than 300 is that stirring is divided equally by the above wooden calcium sulfonate of 200 orders on stirrer, mix, form the water-proofing powder masterbatch, b, with above-mentioned water-proofing powder masterbatch and 525 high strength cements mixed by 1: 26.5, in stirrer, fully stir, mix.Described cement is 525 silicate cements.The time of stirring on stirrer is 20 minutes.
High-performance water-proof cement of the present invention compared with prior art has cost low (every construction cost per square meter is 30% of " four oily three felts "), easy construction, good water-proof effect, bonding strength advantages of higher, and can significantly improve the water impermeability of concrete mortar, reduce water-intake rate, do not hinder that body of wall is ventilative, acid-and base-resisting, do not chap, do not expand, non-warping, very strong sticking power is arranged.
