Artificial quartz stone checkered plate and process thereof

Abstract

The invention relates to an artificial quartz stone checkered plate and a manufacturing process thereof, in particular to an artificial quartz stone with stone patterns and colours and a manufacturing process thereof. The artificial quartz stone comprises backing material and pattern material, wherein the backing material comprises the following components in weight proportion: 50-75% of 0.18-1.18mm quartz particles, 20-35% of 0.005-0.18mm quartz powder, 0.01-10% of pigment, 0.1-1% of silane coupling agent, 8-18% of unsaturated polyester resin and 0.8-2% of peroxided (2-ethylhexoic acid) tertiary butyl ester; and the pattern material comprises the following components in weight proportion: 60-90% of 0.18-1.18mm quartz particles, 0-10% of 0.005-0.18mm quartz particles, 0.01-20% of pigment, 0.1-1% of silane coupling agent, 4-13% of unsaturated polyester resin and 0.4-1.5% of peroxided (2-ethylhexoic acid) tertiary butyl ester. Thus, the appearance of the artificial quartz stone checkered plate is close to natural stone, total specific area of the quartz particles is increased, namely contact area of the quartz particles and the unsaturated polyester resin is increased, number of chemical bonds inside the quartz is increased, bending strength of the artificial quartz stone checkered plate reaches up to more than 60MPa, compression strength reaches up to more than 200MPa, and physical properties of the artificial quartz stone are greatly enhanced.

Description

technical field [0001] The invention relates to an artificial quartz stone and its manufacturing process, in particular to an artificial quartz stone with stone pattern and color and its manufacturing process. Background technique [0002] Natural marble has rich, beautiful and natural patterns, and is a good decorative material, but because its main component is calcium carbonate, which has low hardness and is easy to scratch, it is not suitable for flooring. Although artificial quartz stone has high hardness, 5-7 Mohs hardness, it is difficult to scratch, so it is a good material for flooring. However, due to the lack of natural texture and color of stone, the grade of artificial quartz stone cannot be greatly improved. The patterned quartz stone produced abroad is in the shape of bean curd flower, the color is unnatural, and there is no texture of natural natural stone. Because artificial quartz stone is a new type of stone artificially synthesized by more than 85% quar...

Problems solved by technology

[0003] Domestic conventional quartz stone products are mainly monochrome at first. With the development of the market, monochrome quartz stone can no longer meet the constantly updated aesthetic requirements of the market. In the past two years, there have been complex-color plates imitating natural granite, but the color is relatively dull. , no natural texture

In addition, the granules in the conventional product formula mostly use 0.2mm-4mm quartz granules in a graded ratio. The granules above 1mm are prone to defects and affect the strength of the product. The bending strength of this type of product is 30-50Mpa, and the compressive strength is 130-180Mpa.
