Description
Technical field
The present invention relates to a kind of material of construction and production method thereof and using method thereof, particularly a kind of waterproof type cement additire and production method and using method thereof.
Background technology
Cement is a kind of foundation construction material, be widely used, main application is built, whitewashes, is pasted ceramics by laying bricks or stones, makes cement brick, Cement Concrete, cement products etc., and the problem of the performance deficiency of cement products own also is the difficult problem that the technician in industry field is exploring.In the prior art, all be by in cement, adding external additive refinforced cement water-proof function, as being combined with cement, the glue series products solves waterproof problem, in case and waterproof layer destroys because of expanding with heat and contract with cold after reaching certain limit between in use, this function just can't be repaired it, the defective that generation can't remedy.Generally speaking, the problem of a general character of all kinds water-resisting agents on the market; Be the water-proof function that does not remove to improve Cement Concrete and cement mortar at the performance deficiency of cement products itself, generally speaking, there are the following problems for the performance of cement products itself:
1, the endurance quality of Cement Concrete is bad, and the coefficient of thermal expansion and contraction of cement is very big, the weathering of ftractureing easily; The cement high thermal resistance is poor, explosion easily;
2, the sand-cement slurry water-repellancy is very poor, and on reason was that 30% cement does not utilize, the utilization ratio of cement only was about 67%～70%, and cement knot stone roller loses with current, and in use workability is poor, degree of being stained with is poor for cement, bleeding, layering easily.
3, cement belongs to the alkaline species goods and materials, and is excessive as consumption, solidifies the back to the bigger pollution of underground water generates.
Above-mentioned defective all is the performance deficiencies that unavoidably cause Cement Concrete and sand-cement slurry because of the defective of cement products itself, and the performance that only changes itself still can't address the above problem.
In sum, existing waterproof type cement additire need be further improved.
Summary of the invention
The object of the present invention is to provide a kind of waterproof type cement mortar additive, it can improve the water-repellancy of Cement Concrete and sand-cement slurry, and reaches the effect of saving cement when guaranteeing use properties.
Another object of the present invention is to provide a kind of production method of waterproof type cement additire, it can satisfy above-mentioned requirements.
Another object of the present invention is to provide a kind of using method of waterproof type cement additire, it can reach the effect of saving cement consumption.
Technical scheme of the present invention is: a kind of waterproof type cement additire, its component and weight percent are dodecyl phenol polyethenoxy ether 20%～25%, hydroxyethyl ether cellulose 10%～15%, stearic acid 15%～25%, polyvinyl lactam 5%～10%, flyash 25%～50%.
As to further improvement of the present invention, its component and weight percent are 40,000 molecular weight extensions 10% of dodecyl phenol polyethenoxy ether 20%, hydroxyethyl ether cellulose, stearic acid 15%, polyvinyl lactam 5%, flyash 50%, described hydroxyethyl ether cellulose are 40,000 molecular weight extensions of hydroxyethyl ether cellulose.
A kind of production method of waterproof type cement additire is characterized in that it is to take by weighing each starting material in proportion, joins in the encloses container successively and mixes, and be 20～30 ℃ in temperature, operating pressure is to carry out complex reaction under the condition of 10MPA; Reaction product is stirred, makes it become uniform miscellany, get final product finished product.
A kind of using method of waterproof type cement additire, it is used to prepare the sand-cement slurry of powder exterior wall, and the component weight ratio of sand-cement slurry is: cement, sand, waterproof type cement additire are 1: 4.5: 0.2～1: 5: 0.2.
