Problems solved by technology

However, due to the use of magnesium chloride and chelating agents, the water resistance is greatly reduced. At the same time, heating is required during the processing, which makes the process complicated and not conducive to energy utilization. It is difficult to be widely used in the external decoration market.

Abstract

The invention discloses an artificial moulding stone of cladding cement base in the agricultural technical domain, which comprises the following parts: 25-30% common white silicate cement, 60-65% limestone particle, 5-10% zeolite powder, 1-1.5% resin powder, 0.15-0.18% high-effective dehydragent, 0.15-0.2% defoamer and 0.48-1.12% dye.

Description

technical field [0001] The invention relates to a stone used in the technical field of building materials, in particular to an external cement-based artificial molded stone. Background technique [0002] Stone is the most primitive building material, and the buildings it creates are thick, safe and reliable, so modern people have a strong sense of dependence on stone buildings. Although stone is rarely used as a structural material in buildings today, it is widely used in interior and exterior wall decoration. However, natural stone mining and processing are difficult and have a relatively large proportion, so there are certain defects and deficiencies as external stone materials. In recent years, there have been some artificial stones appearing and applied, the most typical of which are artificial marble countertops. [0003] After searching the literature of the prior art, it is found that Chinese Patent Publication No.: CN1673164A, Patent Name: Manufacturing Method of A...
