Abstract
The present invention relates to the prefabricated building material technology. The technological scheme is that light-burnt magnesia, flyash, sawdust, hemp cut and improver in certain proportion are mixed in a stirrer; mixing with water solution of magnesium chloride while stirring; extruding the mixture to form light magnesia cement wall board. The present invention has the advantages of simple production process, high performance and low cost.
Description
Technical field: the present invention relates to the pre-formed technical field of constructional materials, is a kind of magnesium cement (magnesia oxychloride cement) production process of light wall board more specifically.
Background technology: the cement class wallboard that uses need foam for reaching lightweight at present, and this just causes intensity and toughness all bad, is prone to wall body slit, and the price height has influenced its penetration and promotion.
Summary of the invention:, the objective of the invention is to invent a kind of production process of light wall board of magnesia cement for overcoming above-mentioned shortcoming.Its technical scheme is: earlier light calcined magnesia, flyash, saw foam bits, hemp cut and modifier are carried out batching, pour mixer then into and do mixing; Be metered into magnesium chloride brine again and stir, the slip that stirs is sent into single lead screw ex truding briquetting machine and is carried out extrusion modling and make light wall board of magnesia cement.Their proportioning is: light calcined magnesia is 100 weight portions, and magnesium chloride brine is 160～240 weight portions, and modifier is that calcium superphosphate and calcium lignosulfonate are 3～7 weight portions, and flyash is 20～60 weight portions, and saw foam bits are 100～140 weight portions.Advantage of the present invention is: manufacturing process is simple, the light wall board intensity height of making, and hardness is good, local toughness and to hold poly-power good.As the main body filler sheet material is reached with a large amount of saw foam bits and be lightweight, kept intensity and toughness again, add the distinctive viscosity of magnesium cement and make wallboard outstanding especially on the seam effect of installing.Not foaming with magnesium cement does not need cement slurry to wipe one's face on the surface of body of wall after the wall board made becomes wall again, has promptly improved efficiency of construction, has saved flat cost again.And this board cost reduces greatly and is easy to penetration and promotion.
The specific embodiment: get light calcined magnesia (wherein content of magnesia 70～90%) 100 weight portions, inserts saw foam bits (wheat straw, straw, Chinese sorghum, seeding corn and other crops straw pulverize after all can) 100～140 weight portions, flyash is 20～60 weight portions, some and the modifying agent of hemp cut be calcium superphosphate and lignin sulfonic acid ca proportion be 3: 1 be that 3～7 weight portions are prepared burden, pour mixer then into and do mixing; Adding magnesium chloride brine (proportion is 1.16～1.25) again stirs for 160～240 parts, the slip that stirs is sent into single lead screw ex truding briquetting machine and is carried out extrusion modling, natural curing at normal temperatures 2～3 days, plate is played in size cutting back on request, the check warehouse entry and piling, light wall board of magnesia cement was made in natural curing in 20～25 days again.
