Benefits of technology

[0027]1. The invention employs cullet, calcium carbonate, and resin as the main raw materials to prepare an artificial stone plate; no natural quartz is used, and hence the raw material cost is low. A reasonable ratio of cullet to calcium carbonate reduces the use of resin, which further reduces the raw material cost.
[0028]2. Through a reasonable combination of different particle sizes of cullet, calcium carbonate, and resin, the composite plate of the present invention ha...

Problems solved by technology

The preparation of the sintered type is similar to the preparation of ceramic bricks, that is, it is obtained by firing at a high temperature; the cost of the stone plates obtained this way is high.
Although artificial granite is inexpensive, it has poor chemical resistance, thus its application is limited.
However, due to the gradual depletion of natural high-quality quartz, some researchers have introduced glass into the formula to replace part of the quartz.
However, due to the amorphous nature of glass, the pulverization of the glass results in a material that has a lot of corners and edges and has a large specific surface area, resulting in poor fluidity, thus more resin is required compared with using quartz.
In the aforementioned patent, the amount of resin is 8%-16%, which increases the cost of the artificial stone.
The excessively high resin content ...

Abstract

A composite plate is mainly made from the following raw materials in percentage by weight: 35% to 45% of calcium carbonate, 45% to 55% of cullet, 5% to 15% of unsaturated polyester resin, 0.1% to 1% of a curing agent, 0.1% to 1% of an auxiliary agent, wherein a ratio of an amount of the calcium carbonate to an amount of the cullet is 0.75%. The invention employs cullet, calcium carbonate, and resin as the main raw materials to prepare an artificial stone plate; no natural quartz is used, and hence the raw material cost is low. A reasonable ratio of cullet to calcium carbonate reduces the use of resin, which further reduces the raw material cost. Through a reasonable combination of different raw materials, the composite plate of the invention has physical and chemical properties and decorative abilities that are similar to those of traditional artificial quartz stone.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of Chinese Patent Application No. 201910607431.7 filed on Jul. 8, 2019, the contents of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to the technical field of construction materials, in particular to a composition plate and a preparation method thereof.BACKGROUND OF THE INVENTION[0003]With the continuous improvement of living standards, people pursue a higher quality of life, and various artificial stones are being widely used. In terms of preparation methods, existing artificial stones can be divided into three types: a sintered type, a heat-curing type, and a low-temperature curing type. The preparation of the sintered type is similar to the preparation of ceramic bricks, that is, it is obtained by firing at a high temperature; the cost of the stone plates obtained this way is high. The plate obtained by low-temperature c...
