Lightweight artificial quartz stone and production process thereof

Abstract

The invention aims to provide a lightweight artificial quartz stone and a production process thereof. The lightweight artificial quartz stone is jointly formed by a prefabricated material of an artificial board and a prefabricated material of a lightweight layer. The prefabricated material of the artificial board is prepared from the following components in parts by weight: 100 to 150 parts of white cement, 20 to 90 parts of silica powder, 200 to 300 parts of quartz chips, 50 to 100 parts of stone aggregate, 30 to 36 parts of water, 1.5 to 3 parts of a water reducing agent, 70 to 80 parts of resin, 5 to 10 parts of color paste and 0.1 to 0.2 part of a curing agent. The prefabricated material of the lightweight layer is prepared from the following components in parts by weight: 6 to 10 parts of hollow glass microspheres, 20 to 60 parts of silica powder and 30 to 70 parts of resin. The production process for the artificial quartz stone comprises the following step: S1, preparation of the prefabricated material of the artificial board: weighing raw materials consisting of 100-150 parts of the white cement, 20-90 parts of the silica powder, 200-300 parts of the quartz chips, 50-100 parts of the stone aggregate, 30-36 parts of the water, 1.5-3 parts of the water reducing agent, 70-80 parts of the resin, 5-10 parts of the color paste and 0.1-0.2 part of the curing agent, adding the raw materials into mixing equipment for mixing at normal temperature so as to obtain the prefabricated material of the artificial board for later use.

Description

technical field [0001] The invention relates to the field of artificial quartz stones, in particular to a lightweight artificial quartz stone and a production process thereof. Background technique [0002] With the development of the modern architectural decoration industry, people's requirements for environmental decoration have become more extensive. However, many precious products on the earth are being crazily mined and plundered, and a large number of non-renewable materials are facing depletion and disappearance. The birth of colored artificial stone as a renewable material is the product of the environmental beautification trend of this era. Especially because the product is rich in color, diverse in shape, durable, simple in processing, low in price, and at the same time has the characteristics of green energy saving and environmental protection, it can fully meet the contemporary high standards and requirements of various material effects for architectural decorati...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in order to solve the problem of uneven grain distribution and poor appearance of traditional artificial stone products, some artificial stone formulas will add light materials such as wood powder, vermiculite powder, and perlite powder to the artificial stone formula, but In the actual process of product preparation, due to the poor compatibility between such particles and the slurry, the light-weight slurry will be suspended in the upper layer of the slurry after mixing, resulting in the lower density of the upper layer and the lower density of the artificial quartz stone. Defects with high density, that is, uneven distribution of lightweight slurry, resulting in poor stone stability
