Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of artificial stones, in particular to a microcrystalline stone composite quartz stone plate. Background Art
[0002] Microcrystalline stone is a new type of green and environmentally friendly high-end building decoration material made of natural tailings materials and high-temperature sintering. It has a flat and clean board surface, uniform color, clear and elegant texture, soft and crystal luster, brilliant colors, hard and delicate texture, non-absorbent and anti-pollution, acid and alkali resistance and weathering resistance, green and environmental protection, no radioactive poisoning, etc. Because microcrystalline stone does not contain resin, it will not turn yellow or age when used on outdoor countertops or walls. Quartz stone is made of unsaturated polyester resin, quartz sand powder filler, pigment, a small amount of initiator, and is made through pressing, shaping, sintering and other processing procedures. It has high flexural strength, environmentally friendly waste utilization, low energy consumption and green energy saving. The advantages of microcrystalline stone are good weather resistance and no discoloration. The disadvantages are that the thick microcrystalline stone has a high firing cost and low yield, and the thin microcrystalline stone is not strong enough to be directly used for countertops. Quartz stone is a high-flexural and high-strength board that is cured by low-temperature heating at 80-100 degrees. It is low-cost, environmentally friendly and energy-saving, but the disadvantage is that the resin is easy to yellow and cannot be directly used for outdoor countertops. Therefore, a board material is needed that is both weather-resistant and anti-yellowing and has high strength so that it can be directly used as an outdoor desktop board or dry hanging.
