Reproduced stone and preparing method thereof

Abstract

The invention belongs to a building material product and a preparation method thereof, in particular to a reconstituted stone and a preparation method thereof. The structure of the reconstituted stone sequentially comprises: a colored sand decorative layer, a structural reinforcement layer and a support layer; A structural reinforcement layer is laid on the inner side of the decorative layer, and the structural reinforcement layer is used to reinforce the reconstituted stone sheet; the support layer is arranged in the structural reinforcement layer, and the support member is used for integrally fixing the reconstituted stone sheet . The invention solves the shortcomings of the traditional method, such as heavy weight, high temperature and other conditions, rough texture, single color, deformation and load-bearing, etc. specialty.

Description

Technical field: [0001] The invention belongs to a building material product and a preparation method thereof, in particular to a reconstituted stone used for urban sculpture and other landscape constructions and a preparation method thereof. Background technique: [0002] With the continuous improvement of environmental beautification and environmental protection requirements, more and more various decorative materials are used in urban sculpture, landscape and architectural decoration, such as natural stone, sandstone, reconstituted stone and so on. These decorative materials should not only consider the richness of shape and color and the texture as close as possible to natural stone products, but more importantly, they should combine the characteristics of corrosion resistance, pollution-free and make full use of external recycling resources. [0003] In the existing reconstituted stone technology, the main technical problems are: [0004] 1. The existing technology use...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing technology uses benzene board to make the model; cement is used as the adhesive. Due to the characteristics of the cement itself, the curing time of the product increases, which prolongs the production cycle of the product

[0005] 2. The content of resin used in the raw materials of the existing reconstituted stone decorative layer is low, often below 20, because the low content of resin often leads to poor toughness and firmness of the product, brittle and not firm, poor adhesion, and low impact resistance , and often the products are very thick and heavy, which is very difficult to carry and increases the burden on the building foundation

[0006] 3. The stone powder used for the existing reconstituted stone has a large particle size, and 20-60 mesh stone powder is mostly used, which directly causes an increase in the gap between the color and texture and the natural stone.

[0007] 4. In the production of the decorative layer, the existing technology uses monochromatic stone powder to make the finished product and then color it or add color paste or natural stone powder to the resin for dyeing, which also makes the color and texture of the reconstituted stone hard, and it is formed with natural stone. certain difference

[0008] 5. In the surface treatment of reconstituted stone, the existing technology often uses grinding for surface treatment, which is time-consuming and inefficient, and the texture and color are uneven

[0009] 6. In the production of products, other reconstituted stones often have requirements for temperature. Generally, there is a process of steaming and curing, which has certain requirements for production, and the construction conditions are high.

[0010] 7. The quality of the product is heavy. Since the thickness of the existing reconstituted stone products is generally more than 20mm to 50mm, the weight is heavy, which increases the burden on the building and the burden on the building foundation.
