Abstract
The invention relates to a thin magnesite powder coal ash decorative plate and a preparation method thereof. Raw materials of the thin magnesite powder coal ash decorative plate consist of the following components in parts by weight: 20 to 35 parts of magnesia, 10 to 20 parts of superfine coal ash, 15 to 25 parts of silicon dioxide hydrosol with percentage concentration by weight of 10 to 15 percent, 20 to 30 parts of a magnesium chloride liquid with specific gravity of 1.2 to 1.5, and 0.5 to 2 parts of phosphoric acid with specific gravity of 1.0 to 1.3. The thin magnesite powder coal ash decorative plate has a thickness up to 3 to 5 mm, high strength, compressive strength not smaller than 20MPa, greatly reduced water absorption not greater than 3 percent, strong fireproof performance, stable plate stability, a wrapping rate smaller than 1 percent after the bottom surface is soaked in water for 3 days, good wear resistance and strong durability.
Description
Technical field
the present invention relates to material field, particularly relate to a kind of magnesite pulverized fuel ash decorating plate and preparation method thereof.
Background technology
The magnesite decorative being pressed into 5 mm thick in prior art often has intensity difference, the shortcoming that water-intake rate is high, and therefore, research and develop a kind of intensity high, the magnesite decorative that water-intake rate is low has very high actual value.
Summary of the invention
The object of the present invention is to provide a kind of can with magnesia and microfine fly ash for main raw material make slim magnesite pulverized fuel ash decorating plate and preparation method thereof,
the technical scheme that the present invention solves the employing of its technical problem is as follows:
A kind of slim magnesite pulverized fuel ash decorating plate, raw material is made up of the component of following weight part:
Magnesia 20-35 part
Microfine fly ash 10-20 part
Silica hydrosol weight percent concentration is 10-15% 15-25 part
Magnesium chloride liquid proportion 1.2-1.5 20-30 part
Phosphoric acid proportion 1.0-1.3 0.5-2 part
The preparation method of described a kind of slim magnesite pulverized fuel ash decorating plate, concrete steps are as follows:
1) magnesia and microfine fly ash are fully mixed; 2) add magnesium chloride liquid again, phosphoric acid mixes; 3) finally silica hydrosol is added; 4) in injection molding machine; 5) thin plate is pressed into 5-8Mpa; 6) maintenance 10-15 hour, the demoulding; 7) spraying and decorating plate surface layer, dries.
Advantage of the present invention: slim magnesite pulverized fuel ash decorating plate thickness of the present invention can reach 3-5mm; Intensity is high, and ultimate compression strength is not less than 20Mpa; Water-intake rate reduces greatly, is not more than 3%; Fire resistance is strong; Sheet material stability is strong, and bottom surface 3 days warpage rates of soaking are less than 1%; Wear resistance is good, and weather resistance is strong.
