Problems solved by technology

[0006] In view of the problems raised by the background technology, the purpose of the present invention is to propose a synthetic quartz stone preparation process imitating the three-dimensional texture of natural stone. The pattern texture of the prepared synthetic quartz stone has a strong sense of three-dimensionality, rich colors, and a texture comparable to natural stone texture. It has the advantages of corrosion resistance, high strength, flatness, not easy to deform, and no delamination, which solves the problems of poor texture, poor strength and corrosion resistance of existing synthetic quartz stones

preparation example Construction

[0054] (1) In the existing preparation process of synthetic quartz stone, the adhesive used is unsaturated polyester resin, and styrene is added as diluent and crosslinking agent in the existing unsaturated polyester resin. On the one hand, styrene will volatilize into the production workshop during the production process, which is not conducive to the health of employees; on the other hand, styrene and the iron filings mixed in the quartz ore during the crushing process will have a miscible reaction, and the gray-black color will affect the whiteness of the board surface. In order to improve the whiteness of the board surface, titanium dioxide needs to be added. The shading effect of titanium dioxide affects the transparency of the surface layer, making it difficult for the surface layer to present an ideal three-dimensional texture effect. The fabric of the present invention adopts epoxy resin without styrene, which reduces the volatilization of styrene in the production work...

Embodiment 1

[0115] A preparation process of synthetic quartz stone imitating the three-dimensional texture of natural stone, comprising the following steps:

[0116] a1. Pattern texture scanning: Send the natural stone slab to a high-resolution scanner, scan the texture on the surface of the natural stone slab and form a graphic file;

[0117] a2. male mold making: the graphics file is input into the engraving machine (the depth of the natural stone pattern texture color in the graphics file corresponds to the depth of the engraved knife), and engraving is carried out on the male mold material (being specifically an aluminum alloy plate) to obtain a material with For a three-dimensional concave-convex textured male mold, the surface of the male mold is coated with a release agent (specifically polyvinyl alcohol solution);

[0118] a3. Master mold making: On a flat and clean platform, use a level to check and adjust the platform feet until it is completely level. The male mold is placed o...

Abstract

The invention discloses a preparation process of synthetic quartzite imitating three-dimensional textures of natural stone. The preparation process comprises the following steps: a, manufacturing a mold, specifically, scanning textures on the surface of a natural stone plate and forming a graphic file; manufacturing a male die and a female die with three-dimensional concave-convex textures according to the graphic file; b, preparing a backing material, specifically, uniformly stirring raw materials of the backing material, wherein the raw materials of the backing material comprise resin, and the resin is unsaturated polyester resin; and c, pressing the backing material, specifically, uniformly spreading the backing material on the female die, strickling, vacuumizing, and carrying out vibration pressing. According to the preparation process of the synthetic quartzite imitating the three-dimensional textures of the natural stone, the prepared synthetic quartzite is strong in pattern texture three-dimensional sense, rich in color and comparable with the textures of the natural stone, and has the advantages of corrosion resistance, high strength, smoothness, difficulty in deformation and no delamination, and the problems that existing synthetic quartzite is poor in texture, strength and corrosion resistance are solved..

Description

technical field [0001] The invention relates to the technical field of quartz stone production, in particular to a preparation process of synthetic quartz stone imitating the three-dimensional texture of natural stone. Background technique [0002] Synthetic quartz stone is a kind of synthetic stone. It is made of quartz particles or a certain amount of glass particles as aggregate, with quartz powder as filler and unsaturated polyester resin as binder. After vacuuming, vibration compaction, The synthetic stone processed by curing and other steps has a hard texture and a dense structure, and has characteristics such as wear resistance, pressure resistance, high temperature resistance, corrosion resistance, and penetration resistance that other decorative materials cannot match. Quartz stone is widely used in public buildings such as hotels, restaurants and banks, as well as home decoration such as kitchen countertops, washstands and kitchen and bathroom walls. [0003] Natu...
