Large-grain artificial quartzite plate and preparation method thereof

Abstract

The invention discloses a large-grain artificial quartzite plate, which is prepared from the following raw materials: 4 to 6 meshes of quartz sand, 6 to 8 meshes of quartzite, 8 to 16 meshes of quartz sand, 10 to 16 meshes of quartz sand, 16 to 26 meshes of quartz sand, 16 to 30 meshes of quartz sand, 40 to 70 meshes of quartz sand, 70 to 100 meshes of quartz sand, 325 meshes of quartz flour, 1,250 meshes of quartz flour, a silane coupling agent, a curing agent, an adhesive and a colored pigment. A preparation method comprises the following steps of (1), weighing and taking each component according to a formula; (2), agitation: premixing the weighed and taken quartz sand and silane coupling agent; mixing the curing agent, the decorative colored pigment and unsaturated polyester resin, and then adding the quartz flour into an obtained first mixture to carry out mixing; (3), further scattering a well mixed material, carrying out material distribution, afterwards, sending the material into a plate making mold, and carrying out molding; (4), curing a molded plate, and carrying out thickness determination and polishing deep processing treatment on the molded plate after the curing is finished. The large-grain artificial quartzite plate has the advantages of low resin proportion, bright color, good impact resistance, high compression performance, high bending strength, low possibility of crack, resistance to scratch, good compactness, and the like.

Description

technical field [0001] The invention belongs to the technical field of artificial quartz stone plates, and in particular relates to a large-grain artificial quartz stone plate 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 has rich and natural patterns, and has been widely used because of its natural decorative effect and texture. However, due to limited resources, large-scale paving has problems such as color difference and varying degrees of radioactivity exceeding the standard, low hardness, and easy scratches. , which limits its all-round development to a certain extent. [0003] Artificial quartz stone is a new type of stone material that is made of quartz sand powder as the main filler and unsaturated polyester resin as the binder. Environmental protection...

AI Technical Summary

Problems solved by technology

[0004] Although artificial quartz stone is rich in color, non-radiation, wear-resistant, pressure-resistant, scratch-resistant, corrosion-resistant, anti-aging, and impermeable, it does not have the natural texture and color of marble, so the grade of artificial quartz stone cannot be obtained. improve

At present, there are pattern plates imitating natural marble at home and abroad, but the color is relatively dull and the texture is unnatural

At the same time, due to the complex process and low production efficiency of the pattern type artificial quartz stone plate, and the color of the plate is easy to penetrate each other during the pressing process, the defect rate is high, resulting in less supply and high price.
