CN101100554A - Technique for using polymerization straw to replacing wood - Google Patents

Abstract

A technology for substituting wood with polymerized straw is carried out by taking heavy magnesium oxide 100 proportion, magnesium chloride solution 100-120 proportion, phosphoric acid 5-8 proportion, active silicon dioxide 1-3 proportion and straw powder 1-2 proportion as raw materials, weighing raw materials, preparing proportionally, adding heavy magnesium oxide, straw powder, phosphoric acid active silicon dioxide into magnesium chloride solution 70%, agitating, adding into residual magnesium chloride solution 30%, agitating, loading into mould, adjusting and maintaining. It has excellent substituting strength and fire-resisting performances. It can be used for polymerized artificial fireproof door.
