Problems solved by technology

However, resin-type artificial stone has pungent odor in the production process, poor high temperature resistance, poor alkali and salt corrosion resistance, poor aging resistance, and easy deformation during use. High cooktops, public places with high fire protection requirements, ultraviolet radiation, outdoor environments with alternating cold and hot, etc.
[0006] Inorganic artificial synthetic stone can effectively improve the shortcomings of resin-based artificial stone. At present, the inorganic artificial synthetic stone that can be seen on the market cannot reach the flexural strength of artificial granite and artificial quartz. The development of high-strength inorganic artificial synthetic stone can not only It can effectively improve the shortcomings of resin-based artificial stone, and has excellent decorative effects. At the same time, it can also achieve the high flexural strength of artificial granite and artificial quartz stone, which will have a wide application prospect

Abstract

The invention discloses a high-strength composite inorganic artificial stone and a preparing method thereof; the inorganic artificial stone comprises the following components by the weight percentage: 30-65% of aggregates, 25-60% of cement, 1-10% of a composite modifying agent, 1-5% of a water reducing agent, 0-1.5% of a retarder, and 8-20% of water, wherein the particle sizes of the aggregates are graded according to the weight of the aggregates. The preparing method of the inorganic artificial stone comprises the steps: successively adding the aggregates with predetermined weight particle size graduation, the cement, the composite modifying agent and the water reducing agent into a stirrer successively, uniformly stirring, adding an appropriate weight of water, then uniformly stirring, distributing the material and pressing under a vacuum state, carrying out wet culture and curing, cutting, and polishing to obtain the product. The inorganic artificial stone has the advantages of high bending strength, environmental-protection production process, lower cost, high yield rate of the product, outstanding performance and the like.

Description

technical field [0001] The invention relates to an inorganic artificial stone, in particular to a high-strength composite inorganic artificial stone and a preparation method thereof. Background technique [0002] Artificial stone is a new type of non-radioactive, non-polluting, reusable, green and environmentally friendly building interior decoration material. As a new strategic health and environmental protection product in line with the country's sustainable development, it was introduced into the domestic market in the 1980s. The artificial stones currently on the market are mainly organic artificial stones with polymer resin materials as adhesives, which are mainly divided into three categories: artificial marble (referred to as artificial granite), artificial quartz stone and acrylic. Although our country started late in the artificial stone industry, after more than 20 years of rapid development, it ranks among the top in the world in terms of market size and applicat...
