Inflaming retarding flame-repellent foam core compound light partition wall

Abstract

The invention discloses an inflaming retarding flame-repellent foam core compound light partition wall which comprises an outer wall panel and an inner wall core. The outer wall panel comprises 34 to 60 wt.% of cement, 2 to 16 wt.% of saw dust, 2 to 24 wt.% of rice husk, 4 to 40 wt.% of coal ash, 1 to 4 wt.% of low alkali fireproof gridding cloth, 1 to 4 wt.% of galvanizing wire netting, 0.6 to 2wt.% of water reducer, 2 to 12 wt.% of bentonite, 2 to 8 wt.% of acrylate copolymer emulsion and 15 to 40 wt.% of water. The inner wall core comprises 18 to 30 wt.% of polystyrene particle, 1 to 3 wt.% of hydroxypropyl methyl cellulose, 40 to 60 wt.% of cement, 6 to 13 wt.% of acrylate copolymer emulsion, 1 to 2 wt.% of low alkali fireproof gridding cloth and 10 to 23 wt.% of water. The partitionwall of the invention has the advantages of flame retardant, flame repellent, smog free, light weight, sound insulation, and the like. Furthermore, the invention has creativity, utility model and wide application values.

Description

technical field [0001] The invention relates to a building wall body, in particular to a flame-retardant and fire-resistant foam sandwich composite lightweight partition wall. Background technique [0002] At present, the known sandwich composite wall panels include magnesium oxychloride cement sandwich composite partition wall panels; its panel structure principle: [0003] (1) The formation of magnesium oxychloride cement is mainly based on the reaction of active magnesium oxide in magnesium oxide and chloride ions in magnesium chloride to generate magnesium oxychloride cement. The first is to return halogen to alkali. If the active magnesium oxide in magnesium oxide is less than 60%, the concentration of magnesium chloride is higher than 28% (when the molar ratio of magnesite products is 7:1), the chlorine in magnesium chloride cannot be fully When the ion reaction is complete, excess free chlorine will be formed. In humid climate, the excess free chlorine will return to...
