Problems solved by technology

[0003] As a substitute for natural marble, it is difficult for the granite prepared by the existing technology to have the natural texture (grain) of natural marble, and it is unnatural. In the choice of some high-end decorative materials, more people tend to choose natural marble, which cannot realize the natural texture of natural marble. Reasonable resources

Embodiment 1

[0025] A method for preparing natural reticulated stone includes the following steps:

[0026] (1) Weigh the raw materials according to the mass percentage, and the total mass is 100%. Weigh 46.524% of white dolomite 90 mesh sand, 46.618% of modified calcium carbonate powder, 6.32% of unsaturated polyester resin, 0.45% of mixed pigment, curing Agent 0.08%, accelerator 0.008%; the mixed pigment is composed of Bayerlo’s iron-based pigment and DuPont’s titanium dioxide (R706);

[0027] (2) Add the accelerator to the unsaturated polyester resin and mix for more than 5 minutes, and then set aside; transport the weighed dolomite 90 mesh sand and modified calcium carbonate powder to the mixer through the conveyor belt, and transfer the weighed mixed pigment Put these three materials into the mixer, mix and stir for 5 minutes, then add the mixture of unsaturated polyester resin and accelerator and curing agent into the mixer at the same time and mix at high speed for 18 minutes, the freque...

Embodiment 2

[0031] (1) Weigh the raw materials according to the mass percentage, and the total mass is 100%. Weigh 45.277% of white dolomite 90 mesh sand, 47.725% of modified calcium carbonate powder, 6.46% of unsaturated polyester resin, 0.45% of mixed pigment, and solidification Agent 0.08%, accelerator 0.008%; the mixed pigment is composed of Bayerlo’s iron-based pigment and DuPont’s titanium dioxide (R706);

[0032] (2) Add the accelerator to the unsaturated polyester resin and mix for more than 5 minutes, and then set aside; transport the weighed dolomite 90 mesh sand and modified calcium carbonate powder to the mixer through the conveyor belt, and transfer the weighed mixed pigment Put these three materials into a mixer, mix and stir for 5 minutes, then add the mixture of unsaturated polyester resin and accelerator and curing agent into the mixer at the same time, mix and stir at high speed for 18 minutes, the frequency of high-speed stirring is 65Hz, the process of stirring In, observ...

Embodiment 3

[0035] (1) Weigh the raw materials according to the mass percentage, and the total mass is 100%. Weigh 44.817% of white dolomite 90 mesh sand, 48.15% of modified calcium carbonate powder, 6.52% of unsaturated polyester resin, 0.45% of mixed pigment, and solidification Agent 0.08%, accelerator 0.008%; the mixed pigment is composed of Bayerlo’s iron-based pigment and DuPont’s titanium dioxide (R706);

[0036] (2) Add the accelerator to the unsaturated polyester resin and mix for more than 5 minutes, and then set aside; transfer the weighed dolomite 90 mesh sand and modified calcium carbonate powder to the mixer through the conveyor belt, and manually weigh it. Pour the mixed pigments into the mixer, mix and stir these three materials for 5 minutes, then add the mixture of unsaturated polyester resin and accelerator and curing agent to the mixer at the same time and mix at high speed for 18 minutes, the frequency of high-speed stirring is 65Hz, stirring During the process, observe w...

Abstract

The invention discloses natural-cross-texture engineered stone and a preparation method thereof. When the total mass of the natural-cross-texture engineered stone is counted as 100%, the raw materialsof the natural-cross-texture engineered stone comprise, 44-47% of dolomite 90-mesh sand, 46-49% of modified calcium carbonate powder, 6.3-6.6% of unsaturated polyester resin, 0.45-0.49% of mixed pigment, 0.08-0.1% of a curing agent and 0.008-0.01% of an accelerator. The preparation method comprises the steps: dividing pressed square materials into a plurality of blocks of different sizes, performing slurry spraying or other coloring modes on the surface, then putting the processed blocks back into moulds, and performing secondary press so as to obtain the engineered stone variety with cross textures close to natural textures. The quality of the engineered stone is ensured through optimization of process parameters of two pressing, and the varieties of engineered stone patterns are enriched greatly.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a natural reticulated stone and a preparation method thereof. Background technique [0002] Granite is also called artificial stone, synthetic stone, reconstituted stone, and engineered stone. It uses natural marble scraps and stone powder as the main raw materials, and can also add mosaics, shells, glass and other materials as embellishments. It uses organic resin as a cementing agent. It is vacuum stirred and high-pressure shock to make square materials, and then cured at room temperature (curing) It takes more than 7 days), sawing, grinding, polishing and other processes to make plates. Granite is often used as interior decoration material. [0003] As a substitute for natural marble, it is difficult for the granite prepared by the prior art to have the natural texture (texture) of natural marble, and it is unnatural. In the choice of some high-end decorative ...
