Abstract

The invention discloses lightweight sandstone. The lightweight sandstone is characterized by comprising the following components in percentage by weight: 70-90% of silica sand, 8-21% of organic adhesive and 6-16% of inorganic flame-retardant powder. A production method of the lightweight sandstone is further provided, and comprises the following steps: (1) weighing the components, mixing the weighed inorganic flame-retardant powder and the weighed organic adhesive in a container, and stirring the weighed inorganic flame-retardant powder and the weighed organic adhesive evenly; (2) then addinga catalyst and a curing agent for even stirring; (3) after the silica sand is weighed and is ground to be 30-60 meshes, adding ground silica sand into a mixture in the step (1), and conducting stirring for 10-20 minutes; (4) pouring an obtained mixture into a mould, and conducting compaction and smoothing; and (5) after the mould is placed in a drying tunnel for drying, conducting demoulding. No waste or harmful gas is generated in the production process, no pollution is generated, and waste is turned into wealth; the average sound reduction index of a lightweight sandstone slab is above 30 dB, a sound absorption and reduction coefficient is larger than 0.7, both the average sound reduction index and the sound absorption and reduction coefficient exceed the national standard, and the mechanical performance is good, so that the lightweight sandstone slab is an ideal outdoor acoustic sound absorption material; and the fireproof performance reaches an A grade.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a light sandstone and a manufacturing process thereof. Background technique [0002] Sandstone, as the name implies, is a kind of stone that can be used as a building material when sand is aggregated. Its main component is SiO 2 , Al 2 o 3 , in nature, it is formed through sea-oriented and continental deposition in geological changes, after covering up the original terrain with a large accumulation of sand layers, and then heating and pressurizing in the process of geological changes. This year, with the development of architectural decoration in pursuit of environmental protection and health, and advocating the new concept of natural consumption, sandstone with colorful textures, which is healthy, environmentally friendly and decorative, has become highly sought after among decorative stones. [0003] Sandstone is a high-quality natural stone without li...
