Artificial agglomerated stone imitating natural cracks and production process thereof

Abstract

The invention discloses artificial agglomerated stone imitating natural cracks. The artificial agglomerated stone comprises the following raw materials: calcium carbonate coarse sand, superfine calcium carbonate powder, unsaturated polyester resin, toner, titanium dioxide, methyl ethyl ketone peroxide, cobalt iso-octoate, a coupling agent, styrene, octadecanoic acid, sodium phenylpropionate and glycerol. Octadecanoic acid and sodium benzoate generate composite acid modification, and glycerol and styrene are added according to a ratio, so that the unsaturated acid content in the unsaturated polyester resin is reduced, the impact resistance of the unsaturated polyester resin is improved, the cracking condition of the artificial stone in the production process is reduced, and the defective rate of the artificial stone product is reduced; the base material is spread into the mold paved with the auxiliary material through the material distributing machine, and the auxiliary material and the base material in the mold can be molded into an artificial stone blank with imitated natural cracks through the artificial stone vibration molding machine in a vibration pressing manner, so that different crack patterns are presented on the artificial stone blank, and the appearance diversification of the artificial stone is improved.

Description

technical field [0001] The invention relates to the technical field of artificial stone production, in particular to an artificial granite imitating natural cracks and a production process thereof. Background technique [0002] With the rapid development of society and the improvement of people's living standards, people's appreciation of beauty has also risen to a certain level. Stone is widely used as a high-grade building decoration material. It is used in indoor and outdoor decoration and the production and processing of various handicrafts. The market demand is increasing. Increase; stone is divided into natural stone and artificial stone. Natural stone refers to the general term for materials that are mined from natural rocks and processed into block or plate materials. Because of their clear texture and high strength, they have many Good use and decorative effect. However, natural stone resources are decreasing year by year, mining is not easy, transportation is diff...

AI Technical Summary

Problems solved by technology

However, natural stone resources are decreasing year by year, mining is not easy, transportation is difficult, construction intensity is high, and there is a certain degree of radiation; in recent years, people have begun to study artificial stone, which is made of industrial raw materials through scientific processes. The artificial stone produced by the manufacturing process has a single appearance, and there is a problem of high defective rate of the produced products
