Embodiment 1

[0015] See figure 1 , figure 2 , image 3 ( figure 1 , figure 2 It is a product cross-sectional view). The composite crystallite slab of the present invention has a substrate layer 2 on which the crystallite decorative layer 1 is compounded. The composite of the substrate layer and the decorative layer adopts conventional technology. The substrate layer is provided with a plurality of longitudinal convex ridges 4 and a plurality of transverse convex ridges 5, the substrate layer is composed of fiber cloth or non-woven fabric and unsaturated resin, and the crystal stone decoration layer is composed of quartz sand and The resin is mixed and solidified, and a metal frame 3 is arranged at the periphery of the crystal stone slab. In this embodiment, the thickness of the substrate layer may be 2-5 mm, and the thickness of the granite decoration layer may be 0.5-2 mm (excluding the size of the bump). The arrangement of the longitudinal convex ridge and the transverse convex ridge can ...

Embodiment 2

[0018] This embodiment is an improvement on the basis of the above embodiments. In this embodiment, the composite of the substrate layer and the decorative layer adopts conventional techniques, including batching, mixing, mold, curing, grinding, and polishing steps. The resins and curing agents used adopt conventional products and technologies, and the surface treatment of crystal stone slabs adopts conventional technologies, which will not be described in detail here.

[0019] In order to produce composite granite slabs closer to the granite pattern, the granite decorative layer of this embodiment includes the following raw materials, and the weight percentage of the raw materials is:

[0020] Resin 30%

[0021] Quartz coarse sand 20%

[0022] Quartz fine sand 30%

[0023] Glass particles 4%

[0024] Silica 1%

[0025] Alumina 1%

[0026] Titanium dioxide 0.1%

[0027] The rest are fillers. The filler can be made of 320 mesh fine stone powder; among them, the proportion of resin ...

Abstract

The present invention relates to a composite crystal granite slab, which has a substrate layer. The key point is that: the substrate layer is compounded with a crystal granite decorative layer, and the substrate layer is provided with a plurality of longitudinal ridges and a plurality of transverse ridges. The substrate layer is composed of fiber cloth or non-woven fabric and unsaturated resin, the crystal granite decorative layer is formed by mixing and curing quartz sand and resin, and a metal frame is set on the periphery of the crystal granite plate. The invention has beautiful appearance, waterproof and acid and alkali resistance, and can be used for decoration of walls, ceilings, floors and furniture.

Description

Technical field [0001] The invention relates to a composite crystal stone slab. The crystal stone slab is a composite crystal stone decorative layer on a substrate layer. A plurality of longitudinal convex ridges and a plurality of lateral convex ridges are arranged on the substrate layer. Set the metal frame. Background technique [0002] Chinese Patent 01107481.7 discloses a method for manufacturing an artificial stone slab, the artificial stone slab adopts a double-layer structure. The upper layer is a mixture of resin and transparent glass particles or fine transparent quartz particles, and the lower layer is a mixture of color materials, stone materials and resin. Due to the principle of light reflection and refraction, the product has high gloss, transparency and deep feeling. The color of marble or granite is very obvious, and it feels very gorgeous. The invention makes full use of leftovers from the natural stone industry or leftovers from other industries for production....
