Production technology of nature-imitated stone material cast stone

Abstract

The invention discloses a production technology of a nature-imitated stone material cast stone. The technology comprises the following steps: 1, making a die; 2, raw material mixture, water addition and stirring: uniformly mixing raw materials, adding water, and uniformly stirring to obtain a slurry; 3, carrying out pouring molding; 4, maintaining: 5, shot blasting: carrying out shot blasting on the above obtained maintained semi-finished product to make aggregates exposed and make the appearance have the qualitative sense of a natural stone material; 6, carrying out secondary maintenance; and 7, trimming: trimming the above obtained product to make the obtained finished product have orderly and smooth edges and unified specifications. The aggregates of the nature-imitated stone material cast stone produced by using the above technical scheme are exposed, so the unvarnished and rough qualitative sense of the natural stone material is presented; the regular and smooth edges and the unified specifications of the finished product make the product have a beautiful edge joint and can completely replace the natural stone material in order to reduce the excess exploitation of natural resources; and the nature-imitated stone material cast stone can substitute a GRC + coating decoration system in order to eliminate the hidden safety troubles caused by GRC cracking, chapping and the like and reduce the later stage maintenance cost.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a production process for imitating natural stone casting stone. Background technique [0002] At present, in the field of building materials, a large amount of stone decoration is required for indoor and outdoor buildings, walls and floors, garden landscapes and decorations. However, natural stone is expensive and has limited resources, and a large amount of natural stone will destroy a large number of vegetation and destroy the ecological environment. Therefore, people are actively seeking alternatives to natural stone. At present, the main alternatives to natural stone are: GRC (glass fiber reinforced concrete) + coating; cast-in-place concrete + coating. [0003] First of all, the decorative effect of using GRC+ paint to replace natural stone cannot be compared with natural stone, and lacks the texture of natural stone; secondly, the main components of GRC are sulphoalumina...

AI Technical Summary

Problems solved by technology

[0003] First of all, the decorative effect of using GRC+ paint to replace natural stone cannot be compared with natural stone, and lacks the texture of natural stone; secondly, the main components of GRC are sulphoaluminate cement, yellow sand, glass fiber, etc. The disadvantages of GRC are: It is easy to crack and fall off, seriously affecting the appearance of the building and causing safety hazards. The reasons are: the main component has no flexibility, and the strength of the sulfoaluminate cement will decrease with time after hydration; in addition, GRC itself There is no decoration, and it can only be used as a structural material, not directly as a decorative material. Therefore, a layer of paint is added to the outer surface of the GRC for decoration. The combination of the decorative layer of the paint and the GRC has low durability. Therefore, if GRC+ coating is used to replace natural stone, the building needs to be maintained every few years, and the later maintenance costs are higher

[0004] The method of replacing natural stone with cast-in-place concrete + paint cannot compare with natural stone in terms of decorative effect; at the same time, cast-in-place concrete requires on-site formwork, with limited types of shapes, poor precision, high difficulty, and slow construction progress; and it will increase a lot The weight of the building provides the construction cost; the surface of the cast-in-place concrete also needs to be decorated with paint. Also because of the combination and durability of the paint layer, the building needs to be re-maintained every few years, increasing the maintenance cost in the later period
