Abstract
The present invention discloses a magnesium oxychloride cement material capable of maximally reducing its defect and invigorating its properties, and at the same time, adopts a simple production process to produce an extensively-used more perfect decorative board instead of polywood to save timber.
Description
The present invention summarizes the magnesia oxychloride cement matrix material of a kind of improvement of saying so.
Magnesia oxychloride cement is the Sorel initiative, with MgO-MgCl
2-H
2O is the air hardening cementitious materials of essentially consist system.Be characterized in can be under normal temperature and pressure setting and harden.The fast intensity height of initial set, nontoxic fire-retardant and low from the anharmonic ratio Portland cement.Yet it also exists, and volume stability is poor, poor water resistance, easily scum, distortion, dry and cracked, so that falls strong and shortened work-ing life.How to improve above-mentioned shortcoming, reinforcing property and improvement making method have become continuous three general objectives of exploring of Chinese scholars for many years.
Among many modification methods, more representationally be:
(1) in prescription, adds phosphoric acid and phosphoric acid salt and so on (as United States Patent (USP): 4141744; 4185066; German Patent: 2732577) or carbonate, silicate and so on or the like.
(2) filler such as quartz sand, white cement or the like in prescription, have been added (as patent: 91102424.7).
(3) in prescription, add tensio-active agent, water-resisting agents such as resin or organosilicon etc.
Temperature when improving the slurry stirring in addition in addition or heat up curing or extrusion forming etc., though these inventions have improved the water tolerance of magnesia oxychloride cement, increasing aspect such as volume stability has tremendous development, but still has some effects not show or strengthen cost or fall strong or delay time of coagulation or unsatisfactory consequence such as attend to one thing and lose sight of another.
The objective of the invention is to provide a kind of and can at utmost reduce its shortcoming, strengthen the magnesia oxychloride cement material of its performance, adopt comparatively easy production technique simultaneously, thereby produce a kind of can widespread use, more perfect decorative plate need fall trees and produced wooden plywood in a large number to substitute.
Its prescription of magnesia oxychloride cement material of the present invention is as follows:
With active oxidation Mg content in the magnesium oxychloride is foundation, and the mol ratio of magnesium oxide and magnesium chloride is under the prerequisite of 5-9, and its composition and weight ratio are:
Magnesium oxychloride, its active oxidation Mg content are 50% above 35.59-42.15%
Enriched bittern cake, its content of magnesium chloride 45% 16.5-16.57%
Benzene emulsion, its solid content 46% 1.11-1.32%
Ferrous sulfate 0.44-0.53%
Tertiary sodium phosphate 0.23-0.24%
NNO 0.13-0.16％
Flyash or fineness are not more than 180 purpose blast-furnace slag or fineness
Be not more than 180 purpose boiling furnace slag 9.18-9.22%
Talcum powder 5.15-10.76%
Wood chip, its fineness are not more than 40 order 3.2-4.33%
Water 21.58-21.65%
Below for three embodiment:
Example one: magnesium oxychloride 35.59%, enriched bittern cake 16.57%, benzene emulsion 1.11%, ferrous sulfate 0.44%, tertiary sodium phosphate 0.24%, NNO 0.13%, flyash 9.18%, talcum powder 10.76%, wood chip 4.33%, water 21.65%.
Example two: magnesium oxychloride 38.75%, enriched bittern cake 16.54%, benzene emulsion 1.21%, ferrous sulfate 0.48%, tertiary sodium phosphate 0.24%, NNO 0.15%, flyash 9.22%, talcum powder 7.97%, wood chip 3.82%, water 21.62%.
Example three: magnesium oxychloride 42.15%, benzene emulsion 1.32%, enriched bittern cake 16.5%, ferrous sulfate 0.53%, tertiary sodium phosphate 0.23%, NNO 0.16%, flyash 9.18%, talcum powder 5.15%, wood chip 3.2%, water 21.58%.
The manufacture craft of above-mentioned example 1-3 is all described by claim 2-3.
In addition, the manufacture craft of this material is finished under normal pressure and temperature (being preferably 18 ℃).
Magnesia oxychloride cement material of the present invention is on the basis of containing magnesium oxide, magnesium chloride and water composition, adopts strong point in many ways, in additive with the made a concerted effort modifying function of antiseepage frost prevention counnter attack halogen of ferrous sulfate, tertiary sodium phosphate and benzene emulsion.Share with flyash, talcum powder, three kinds of stopping composition of wood chip activity, inertia and cellulosic advantage are comprehensively brought into play, on the stability of improving material and water tolerance, further improve.Just because of the density of middle mutually binding site of chlorine magnesium double salt aquation and pore structure all is enhanced, the intensity of material has also strengthened with regard to corresponding.
In addition, NNO then increases the slip flowability, has cooperated the reasonable arrangement of unique blanking order, makes hydration reaction more all even complete.
Unique is with material of the present invention as being pressed into the decorative plate of different size, and the above and below respectively adds the last layer alkali-free glass fiber cloth when compacting, and the plate flatness and the glossiness that are pressed into are higher, and intensity also is higher than MCP standard among the JC/T568-94, is called moral treasured plate.
As follows with its physical and chemical performance of decorative plate (the precious plate of moral) that this material is pressed into:
| Mass area ratio (KG/m 2) 9.2-7.2 water ratio (%) 9 ± 4.0 water-intake rates (%) that dispatch from the factory are not more than 15.0 quiet intensity in the wrong (mpa) and are not less than 20 | The oar degree (mm) that makes moist is not more than that 2.8 scum tests does not have or slight glossiness (gloss unit) is not less than 60 fire resistances and does not fire body |
