Abstract
The present invention relates to the chloro-magnesium cement of good volume stability, its main raw material is on the water chestnut hardship, magnesium chloride.Adopt zeolite powder, silicon ash, fine-ground fly-ash, kaolin, high-alumina cement as this product outer permeation.Can mix fillers such as sand, stone, xylon (wood chip), glass fibre equally and make the magnesium oxychloride concrete goods.Can be widely used in industries such as machinery, building, building, it has a extensive future, and has better economic, social benefit.
Description
What the present invention relates to is a kind of chloro-magnesium cement of good volume stability, and its international classification number belongs to CO439/02.
Oxyhydrogen magnesium cement (claiming magnesia cement again) is by magnesium oxide (magnesia) and chlorination.A kind of air-setting consolidating material that the magnesium solution mediation forms.After Mr. Sored in 1867 has invented chloro-magnesium cement, more than one since century, people to magnesia cement have that energy consumption is low, characteristics such as fast, the air hardening degree height of condensing, fire prevention and good heat insulating extremely pay close attention to, and wish to enlarge the Application Areas of its goods always.Yet in manufacturing a product, run into a difficult problem, make its range of application be subjected to considerable restraint, a wherein main difficult problem is that product volume stability is bad, show as the back volumetric expansion of making moist, cause and to make physical dimension with it and reach complex-shaped goods more greatly, in order to address this problem, No. 4419196 patents of the Japanese 58-172250 U.S. add polyoxyethylene glycol, macrogol ester or wait and improve its volume stability by mechano-electronic oscillating action such as ultrasonic wave radiation, ultraviolet radiation in magnesium cement.But, make it can't realize large batch of suitability for industrialized production owing to reasons such as above-mentioned chemical additive and equipment cost costlinesses.
The purpose of this invention is to provide the volume stability problem of utilizing a kind of inexpensive method to solve chloro-magnesium cement,, be applicable to the chloro-magnesium cement of industrialized mass to be mixed with a kind of good volume stability.
The concrete practice of the present invention be in the chloro-magnesium cement component, add with contain activated silica, aluminum oxide is the volume stability outer permeation of major ingredient, to improve the volume stability of chloro-magnesium cement, magnesium cement after modification is by containing 5～7 parts of 100 parts of (by weight, as follows) volume stability outer permeations of 80～85% magnesian magnesias, 30～40 parts of magnesium chloride hexahydrates, 40～80 parts of compositions of water.
The magnesia that is adopted among the present invention is by magnesite levigate forming after 750～800 ℃ of calcination.Used magnesium chloride is the aqueous industrial magnesium chloride, and its MgCl content should be more than 45%.Can mix fillers such as sand, stone, xylon (wood chip), glass fibre in the resulting consolidating material of the present invention equally and make the magnesium oxychloride concrete goods.Can be widely used in industries such as machinery, building, building, it has a extensive future.
The used volume stability outer permeation of the present invention is made up of for 5～40 parts 5～100 parts of zeolite powders, 5～30 parts of silicon ashes, 5～100 parts of fine-ground fly-ashs, 5～30 parts of kaolin, high-alumina cement.Easy dried material-taking on-site of the main raw material of above-mentioned outer permeation or use industrial waste.
The resulting chloro-magnesium cement of the present invention is the same with traditional chloro-magnesium cement, also can pour into the goods of different size, shape, its technical process is for after stirring all solid matters all in proportion, magnesium chloride solution that then will the amount of being mixed with magnesium chloride mixes with above-mentioned dry batch, form slip, injection is given in the model, and natural curing got final product the demoulding in 24 hours under 20 ± 8 ℃ of conditions.Finished product was done 31 days through natural gas, the product use of just can dispatching from the factory.
Add in magnesium cement constituent or do not add additive, there were significant differences for its volume stability.Further specify its volume stability below by several embodiment.
Embodiment of the present invention example 1
Contain MgO
2100 parts of 80% magnesias, 40 parts of volume stability outer permeations, 30 parts of magnesium chloride hexahydrates, 50 parts in water.
Contain MgO
2100 parts of 80% magnesias, 30 parts of volume stability outer permeations, 30 parts of magnesium chloride hexahydrates, 42 parts in water.
Comparative example:
Contain MgO
2100 parts of 80% magnesias, 30 parts of magnesium chloride hexahydrates, 35 parts in water.
Its compound method is: by the proportioning of giving, earlier magnesium chloride hexahydrate and water are mixed, make its dissolving form magnesium chloride solution, then magnesia and volume stability outer permeation are mixed, at last magnesium chloride solution and above-mentioned doing are mixed the thing mixing and stirring, be shaped to 4 * 4 * 16Cm standard specimen, at 30 ± 3 ℃, relative humidity is maintenance under 75～85% environment, surveys respectively to make the phase become deflection.
Test result as shown in Figure 1.
As seen from Figure 1, mix the volume stability outer permeation after, not only respectively make phase volumetric expansion amount absolute value reduce greatly.And deflection is tended towards stability.In addition, mix the volume stability outer permeation after its compression strength value descend to some extent.But still kept the chloro-magnesium cement fast solidifying, do not needed advantages such as thermal curing.Intensity level is as shown in table 1.
