Abstract
The invention discloses a calcium carbonate and calcium oxide complexing agent comprising the following components in percentage by weight: 60-80% of calcium carbonate and 20-40% of calcium oxide. Meanwhile, the invention discloses a preparation method of the complexing agent. According to the calcium carbonate and calcium oxide complexing agent disclosed by the invention, the finenesses of the two raw materials are controlled, and the two raw materials are premixed, so that the raw materials are very sufficiently combined to generate a certain binding effect, and furthermore, the problem of poor binding force caused when the single calcium carbonate component is used is effectively avoided in the following use process.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of calcium carbonate calcium oxide recombiner and preparation method thereof.
Background technology
In construction industry, usually need to add a certain amount of calcium carbonate to carry out mixing match.When wet method uses calcium carbonate, rely on the infiltration of other components or glue make bond with the mixing of other components for calcium carbonate effectively can be improved; But, when dry method uses calcium carbonate, because calcium carbonate self-characteristic not easily adheres to, cause mixing rear calcium carbonate and other component bond effects are poor, affect follow-up use.In order to improve the cohesive force of calcium carbonate in dry method uses, more conventional method still adds a certain amount of glue, but due to the intermolecular space of glue comparatively large, be not too applicable to the demand of heavy construction.
Summary of the invention
Goal of the invention: the object of the invention is for the deficiencies in the prior art, provides a kind of calcium carbonate calcium oxide recombiner.
Another object of the present invention is to the preparation method that above-mentioned recombiner is provided.
Technical scheme: in order to reach foregoing invention object, the present invention has specifically come like this: a kind of calcium carbonate calcium oxide recombiner, comprising weight percent is the calcium carbonate of 60 ~ 80% and the calcium oxide of 20 ~ 40%.
Wherein, the fineness of described calcium carbonate and calcium oxide is not more than 80 orders.
Prepare the method for above-mentioned calcium carbonate calcium oxide recombiner, step is, gets the calcium carbonate of weight percent 60 ~ 80% and the calcium oxide of 20 ~ 40% crosses 100 mesh sieves respectively, the calcium carbonate after sieving, calcium oxide mixing was continued 80 mesh sieves after 10 ~ 20 minutes, to obtain final product.
Beneficial effect: calcium carbonate calcium oxide recombiner disclosed by the invention, by the fineness of two kinds of raw materials is controlled, and carry out pre-mixing, raw material can be made first to combine very fully, produce certain bond effect, in use subsequently, effectively prevent the problem of the cohesive force difference brought when calcium carbonate single component uses.
