High-shock-resistance artificial quartz stone sheet material and preparation method thereof

Abstract

A high-shock-resistance artificial quartz stone sheet material comprises the following raw materials: 16-100 mesh quartz sand, 300-1000 mesh quartz powder, an adhesive and a pigment. A preparation method of the high-shock-resistance artificial quartz stone sheet material comprises the following steps: (1) adding quartz sand into a mixer and uniformly stirring at a low speed, then adding quartz powder and stirring at a low speed for 15-25 s, and then performing high-speed stirring for 30-40 s to obtain a mixture; (2) doping the pigment and an auxiliary agent into the adhesive, stirring, pouring into the mixture obtained in the step (1), and performing high-speed stirring for 50-60 s; (3) further dispersing the mixed material through beating, metering and sending to a material distributor for material distribution, and then sending to a plating die, sending the plating die into a molding press and molding under the conditions of vacuum, shaking and pressurization; and (4) curing the molded sheet material, and after curing is finished, performing thickness setting and polishing deep processing. The high-shock-resistance artificial quartz stone sheet material has the advantages of brilliant color, good shock resistance, high compressibility, high bending strength, uneasiness to 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 high-impact artificial quartz stone plate and a preparation method thereof. Background technique [0002] 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. It is formed under high pressure under vacuum and shaped under high temperature. Environmental protection, green new building materials and decorative materials. [0003] At present, the development direction of quartz stone products is mainly in kitchen countertops, bathroom countertops, bar counters, coffee tables, floors and interior and exterior walls, etc. Due to its rich colors and rich product designs, it can replace natural stone, high-grade ceramics, wood and metal decorations. Material. However, artificial quartz stone generally has some physical defects such as uneven dens...

AI Technical Summary

Problems solved by technology

However, artificial quartz stones generally have some physical defects such as uneven density, poor impact resistance, easy breakage, and easy cracking, which greatly limit the large-scale promotion of quartz stones and the durability of products. Quartz stone is the common wish of many countertop processors and cabinet manufacturers
