Problems solved by technology

Through the optimization and improvement of the raw material formula, the mutual cooperation of different raw materials, and the improvement of the preparation method, the invention effectively improves the mechanical properties such as hardness and toughness of the artificial quartz slab, and has strong antibacterial power and long-lasting antibacterial effect. The comprehensive performance of artificial quartz slabs, but in use, it is found that during long-term use, the color of artificial quartz stones is easy to fade under the condition of large changes in light or temperature, resulting in a decrease in the aesthetics of the product

Abstract

The invention belongs to the technical field of building materials, and specifically relates to a two-color artificial quartz stone and a preparation method thereof. The two-color artificial quartz stone includes the following raw materials and their mass fractions: 20%-30% of quartz, 20-30% of artificial quartz particles, Ultra-white glass particles 25-56%, pigment 0.01-0.5%, curing agent 0.01-0.2%, coupling agent 0.01-0.2%, light-transmitting material 0.1-5%, antibacterial agent 0.01-1%, and modified resin 3- 10%. In this invention, by modifying the resin, the prepared quartz stone has high hardness, compressive strength and bending strength, and has no cracks, cracks or blisters on the surface in the heat resistance test, no color change, and excellent performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a double-color artificial quartz stone and a preparation method thereof. Background technique [0002] In the field of architectural decoration, stone has become one of the main decorative materials due to its beautiful, elegant, and strong decorative characteristics. For a long time, natural marble patterns are rich and natural, and have been widely used because of their natural decorative effects and textures. However, due to limited resources, large-scale mining and use will cause shortage of resources, and large-scale paving has color difference and different radioactivity exceeds the standard. Low hardness, easy to scratch and other problems, the wide application of natural marble in the field of architectural decoration is neither scientific nor environmentally friendly. [0003] Artificial quartz stone is a kind of synthetic stone made by man-made m...
