Vacuum stone provided with patterns and preparation technology

Abstract

The invention discloses a vacuum stone provided with patterns and a preparation technology. The technology comprises the following steps that filling unit bodies are prepared; materials are mixed; material distributing is performed, specifically, concave-convex structures are formed on the top surface and / or the bottom surface of a rubber mould, and mixed materials are horizontally paved in the rubber mould, so that the rubber mould wraps the mixed materials; forming is performed, specifically, particle aggregate moves towards one another for filling under the resultant action of vacuum forceand heavy hammer impacting force, gaps of the particle aggregate are filled with the filling unit bodies, a vacuum closed body is formed, and concave-convex grains are formed on the surface of the vacuum closed body; solidifying is performed; filling is performed, specifically, small-diameter solid particles, a toner and an adhesive are made into ingredients, the concave-convex grains of the vacuum closed body taken from solidifying equipment are filled with the ingredients, and waste heat of the vacuum closed body is utilized for solidifying the ingredients, so that the patterns are formed; and grinding is performed, and therefore, the vacuum stone provided with the patterns is obtained.

Description

technical field [0001] The invention relates to a preparation process for making a vacuum stone, and at the same time relates to a vacuum stone made by the preparation process. Background technique [0002] As an important part of building materials, natural stone has been widely used since ancient times because of its diverse colors and easy development. However, with the excessive increase of its mining volume and low mining utilization rate, the mining of natural stone is gradually restricted, especially in European countries, which have banned the mining of natural stone. Moreover, the products in each mining area have unique designs and varieties, which further increases the difficulty in their use. People have been looking for alternatives to it. With the development of the economy, building decoration materials are changing with each passing day. As a new type of decoration material, synthetic stone has great opportunities for development. However, the synthetic st...

Problems solved by technology

However, this bonding method is limited by the bonding strength, and it is difficult to improve the strength of synthetic stone.

In addition, in order to be able to bond all the aggregates together, more resin needs to be used, which increases the amount of resin used. The increase in resin usage not only reduces the strength of synthetic stone, but also brings environmental problems

There is no vacuum stone with a concave-convex structure in the prior art, and the preparation process for preparing the vacuum stone
