AI Technical Summary

Problems solved by technology

At present, there are many kinds of light-weight wall panels manufactured and used in the known technology, including round-hole GRC slats and square-hole GRC slabs, but the main material is cement mortar, which still cannot effectively reduce the bulk density, and the thermal insulation function is not good. Obvious, susceptible to moisture and deformation after drying

Abstract

A polybenzene sandwich building material with light weight is prepared from magnesium oxide, plant ash, powdered coal ash, assistant (efficient water-decreasing agent NB, penetrant OS15, emulsifier OP-10 and melamine), and solution of magnesium chloride (or sulfate). Its advantages are light weight, and low cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to an energy-saving building wall material, in particular to a polyphenylene sandwich lightweight building material and a production method thereof. Background technique [0002] At present, the application of building panels at home and abroad In the early 1990s, Japan used wall panels to build houses, accounting for 64% of the total wall materials; the United States accounted for 47%, Germany accounted for 41%, Poland accounted for 41.7%, and Southeast Asia accounted for 30%. In the 21st century, The application of building boards in various countries has an upward trend, especially the building boards in Eastern Europe and Southeast Asian countries have shown a strong momentum. Domestic sheet metal production situation in recent years, in 1999 the total amount of sheet metal production was 240 million m 2 , accounting for 1.8% of the total wall materials in China, the r...
