A kind of manual sandstone board and preparation method thereof

Abstract

The invention discloses a handmade sandstone plate and a preparation method therefor. The sandstone plate comprises a surface layer and a structure layer connected with the surface layer. The preparation method comprises the steps of performing forming processes of stirring, jetting, primary curing, demoulding, secondary curing and the like according to a scientific and reasonable formula, and performing acid washing or sand blasting and waterproof treatment on a demoulded product to finally form the handmade inorganic sandstone plate with excellent performance. The obtained product can be quickly formed, the use cycle of a mould is shortened, and the production efficiency is greatly improved; and the made inorganic sandstone is richer in effect and better in mouldability.

Description

technical field [0001] The invention relates to a decorative board, in particular to a handmade sandstone board and a preparation method thereof. Background technique [0002] Natural sandstone slabs are the most widely used decorative panels at present. Natural sandstone slabs have the following disadvantages: 1. The color and texture of natural sandstone slabs rely too much on natural mineral resources, resulting in single color, simple shape, and large production costs. Mining, Large-scale equipment such as cutting, polishing, engraving, etc., and the product is heavy, which increases the cost of transportation and installation. In addition, some physical properties are poor, such as bending strength, which is easy to break when the product is thin; 2. Organic materials are used as gel The use of materials will have poor anti-ultraviolet light effect, and the product will easily change color after a long time, with poor weather resistance and short life; 3. Inorganic mate...

[0002] Natural sandstone slabs are the most widely used decorative panels at present. Natural sandstone slabs have the following disadvantages: 1. The color and texture of natural sandstone slabs rely too much on natural mineral resources, resulting in single color, simple shape, and large production costs. Mining, Large-scale equipment such as cutting, polishing, engraving, etc., and the product is heavy, which increases the cost of transportation and installation. In addition, some physical properties are poor, such as bending strength, which is easy to break when the product is thin; 2. Organic materials are used as gel The use of materials will have poor anti-ultraviolet light effect, and the product will easily change color after a long time, with poor weather resistance and short life; 3. Inorganic materials are used as cementitious materials, which have a long production cycle and low production efficiency. It takes about 24 hours to complete the production. mold, and the effect of sandstone is not significant, and there are problems such as sand falling off the surface

However, the current artificial sandstone panels have defects such as poor bending resistance, bending resistance, frost resistance, poor plasticity, poor weather resistance, short life, long production cycle, low production efficiency, and insignificant sandstone effects.
