Description

Reconstructed Quartz Slab

The utility model relates to a novel building decoration material, in particular to a reconstituted quartz stone plate.

The reconstituted stone gets its name because it is made of stone fragments, which are bonded and rebuilt, turning waste into treasure. It is mainly composed of resin and marble fragments. However, this reconstituted stone has shortcomings. The wear resistance is poor; the second is that marble (mainly calcium carbonate) is not acid-resistant, and will react with acid after encountering acid to generate carbon dioxide gas; the third is that after paving and pasting, it is not resistant to wear and the gloss is easy to disappear. What's more frightening is that after encountering acid, due to corrosion, the surface appearance of the reconstituted stone is completely destroyed, which seriously affects the decorative effect of the reconstituted stone.

The purpose of the utility model is to provide a reconstituted quartz stone plate which is acid-resistant, alkali-resistant, super wear-resistant, and can still maintain high gloss after long-term use.

The utility model is composed of an upper layer and a lower layer, the upper layer is a mixture of quartz stone material and resin, and the lower layer is a mixture of marble material and resin. Quartz stone is a mixture of quartz stone grains, quartz ballast, and quartz stone powder. Marble material is a mixture of marble granules, marble ballast and marble powder.

The surface layer of the utility model can reach 60 gloss units after being polished, and since both the quartz stone and the cured anticorrosion resin are resistant to acid and alkali, the surface of the product has the characteristics of acid and alkali resistance. More than 90% of the upper layer of the product is composed of quartz stone. The Mohs hardness of quartz stone reaches 7 grades, which is much higher than that of marble 3 grades, so that the surface of the product has a high degree of wear resistance and can still be maintained after long-term use. high gloss. The lower layer is a mixture of marble material and resin, which has the following advantages: (1) Because the Mohs hardness of marble is much lower than that of quartz, it makes the rough grinding on the back of the product easier, improves production efficiency and saves costs; (2) Marble and quartz Compared with stone, the adhesion with cement is much higher than that of quartz stone. When paving, ordinary cement can be easily bonded firmly, avoiding the use of expensive stone-specific adhesives, which facilitates the promotion and mass use of products (3) The market price of marble is far lower than that of quartz stone, and the use of this double-layer compound can greatly reduce the cost of raw materials; The number is the same, so the shrinkage coefficients of the upper and lower layers of the product are basically the same, and there will be no deformation, which effectively guarantees the quality of the product. The utility model makes full use of leftovers of natural ore resources, comprehensively utilizes resources, has the characteristics of low cost, high production efficiency, stable product performance, etc., and is widely applicable to buildings, halls, and indoor and outdoor decoration of families.

Below in conjunction with embodiment, the utility model is described further.

Fig. 1 is the structural representation of the utility model.

Embodiment 1 (taking the reconstituted quartz stone plate of 600mm * 600mm * 16mm as an example)

1. Mixing of resin and quartz stone

Take 0.54kg of resin, add appropriate amount of curing agent (formyl peroxide) and appropriate amount of coupling agent, and mix well first. Take 4.5kg of 5-mesh quartz stone grains, 1.98kg of 40-mesh quartz stone ballast, and 1.98kg of 200-mesh quartz stone powder. Put the above raw materials into the first mixer and stir for 5 minutes to make them evenly stirred.

2. Mix and stir resin and marble.

Take 0.54kg of resin, add an appropriate amount of curing agent (formyl peroxide), and mix well first. Get 4.5kg of 5 order marble grains, 1.98kg of 40 order marble ballast, 1.98kg of 200 order marble powder, put the above-mentioned raw materials into the second mixer and stir for 5 minutes to make it evenly stirred.

3. Smoothing, oscillation, compounding

Put the quartz stone and resin mixture of the first mixer into a simple mold made of cardboard on the vibration table. a container. Smooth it first, then vibrate for 3 minutes to vibrate and discharge air bubbles, then spread the marble material and resin mixture of the second mixer on the vibrated quartz stone and resin mixture, and continue to vibrate for 3 minutes to make it The upper and lower layers are connected to each other, and air bubbles are discharged, and then, a piece of kraft paper with a specification of 602mm×602mm is covered on the mixture.

4. Heating and high pressure molding

The compounded and oscillated double-layer mixture is supported by the hard paper mold and sent to the molding machine through the conveyor belt. A set of molds (the inner space of the mold is 604mm×604mm×18mm) is installed in the molding machine, which is divided into an upper mold and a lower mold. When the upper and lower molds are opened, the maximum distance is 0.5 meters. The upper and lower molds are equipped with thermocouples and electric heating tubes. The temperature of the upper and lower molds is 145°C. And the double-layer mixture is sent into the lower mold.

The molding machine generates high pressure to close the upper and lower molds. At this time, the pressure is 20MPa. After 5 minutes of heating and high pressure, the upper mold is opened. At this time, the mixture in the mold has solidified and formed. Because there is a hard paper mold around and below the mixture, and a layer of kraft paper on it, it will not stick to the mold. Three automatic square thimbles eject the formed product and put it into the drying room for 24 hours of heating and aging treatment.

5. Rough grinding on the back and polishing on the front

The mixture of quartz stone and resin is defined as the front side, the mixture of marble material and resin is defined as the back side, and the back side is rough ground with a diamond grinding disc to grind off the surface adhesive layer, so that the product can be firmly adhered to the cement mortar when laying, and ensure For the flatness of the back, when the back is ground flat and becomes rough, and the stone rice is completely exposed (about 1.5mm thickness is worn away), the product is turned from the back up to the front side by the automatic turning device for front polishing. Polishing wears about 0.5mm thickness, and the product thickness after polishing is about 16mm.

6. Cutting

Put the polished product on the cutting machine for trimming and cutting, cut into the specifications of 600mm×600mm×16mm, and leave the factory after classification, inspection and packaging.

In this way, the upper layer of the manufactured quartz stone plate is a mixture 1 of quartz stone material and resin, and the lower layer is a mixture 2 of marble material and resin.

Claims (3)

1, a kind of reproduced quartzite slate is characterized in that being made of the upper and lower, and the upper strata is the mixture (1) of quartzy building stones and resin, and lower floor is the mixture (2) of Dali building stones and resin.
