Problems solved by technology

[0004] However, the artificial stone in the prior art also has its inherent disadvantages, such as the low strength of the processed stone, and it is prone to breakage or cracks when exposed to the sun or impacted by utensils during use. Large and easy to consume more manpower and material resources, and because the existing artificial stone has a high density and consumes a lot of raw materials, the manufacturing cost is too high

Abstract

A low-density high-strength imitation stone composite material comprises the following raw materials by weight: 60 to 85 percent of an inorganic raw material, 8 to 20 percent of unsaturated resin, 1 to 4 percent of silicone rubber, 0.5 to 15 percent of bagasse fiber, 0.5 to 2 percent of a coupling agent, 0 to 2 percent of a coloring agent, and 0.5 to 3 percent of a cross-linking agent. As high-strength vegetable fiber--bagasse fiber is applied to preparation of imitation stone, and the other raw materials are added through tests, the strength, the weatherability and the photostability of the imitation stone composite material are improved, the weight of the imitation stone composite material is remarkably reduced, the obtained imitation stone composite material is low in density, and convenience is brought for energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of artificial stone materials, in particular to a low-density and high-strength imitation stone composite material and a preparation process for the imitation stone. Background technique [0002] Stone mining brings more than 70% of the waste rock materials, and the disposal of these waste rock materials or occupation of land for stacking or landfill damages a lot of valuable land, making stone resources a major public hazard that endangers the environment. These waste rocks are selected except for the production of a part of colored stone sand, handicrafts, and some light and heavy calcium carbonate produced from high whiteness marble waste, and there is no effective and economically valuable method to utilize them. Everywhere in various mining areas, various colored rocks and slag blocks can be seen forming mountains and ridges, filling the ravines, and the damaged environment is prone to form mudslides to...
