Abstract
The invention discloses a cement retarder which comprises the following components by weight: 1-5 parts of 1-hydroxyethylidene-1,1-diphosphonic acid, 3-8 parts of urea, 15-35 parts of a phosphorus slag powder, 2-6 parts of tartaric acid, 7-10 parts of sodium sulfate, and 20-30 parts of water. The cement retarder disclosed by the invention allows waste to be turned into treasures, adopts the II-class general industrial solid waste phosphorus slag powder as the main ingredient, not only has low manufacturing cost, but also allows the using effect to be not affected by the environmental temperature.
Description
Technical field
The present invention relates to a kind of cement setting retarder.
Background technology
Cement setting retarder is a kind of in cement additire, and in the grout using while being conventionally used in oil, gas well cementing job, cement setting retarder manufacturing cost of the prior art is higher, and result of use temperature influence is large simultaneously.
Summary of the invention
Technical problem to be solved by this invention, is just to provide a kind of low cost of manufacture, and while result of use is the cement setting retarder of temperature influence not.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A cement setting retarder, comprises the composition of following weight content: 1-5 parts of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, 3-8 parts, urea, 15-35 parts of phosphorus slag powder, 2-6 parts, tartrate, 7-10 parts, sodium sulfate, 20-30 parts, water.
The invention has the beneficial effects as follows:
Cement setting retarder disclosed in this invention, turns waste into wealth, and using II class general industrial solid waste phosphorus slag powder is main component, and not only low cost of manufacture, and result of use is not subject to the impact of envrionment temperature.
