Inorganic vitrified microbead thermal insulation mortar with low heat conductivity coefficient, preparation method and equipment
The invention provides a component formula of inorganic vitrified microbead thermal insulation mortar with low heat conductivity coefficient. The inorganic vitrified microbead thermal insulation mortar is prepared from the following raw materials in parts by weight: 45-63% of cement, 20-30% of vitrified micro beads, 5-10% of construction waste micro powder, 0.75-1.2% of renewable latex powder, 0.3-0.5% of cellulose ether and 2.0-2.5% of a starch-grafted anionic-nonionic internal curing agent; and the ratio of the materials to the water is 1.1: 1. The invention also discloses a preparation method and equipment of the inorganic vitrified microbead thermal insulation mortar. The equipment is provided with the scraping plates, materials on the inner wall and the bottom of the stirring tank can be scraped off, stirring blades are designed to be in a vertically-perpendicular long-strip-shaped sheet shape, a certain included angle is formed between the stirring blades and the stirring direction, the materials can be stirred and mixed evenly through the design, the materials can slide along the surfaces of the stirring blades, the stirring blades are prevented from colliding with the materials in the front face, the damage to the spherical closed granular glass beads is reduced, so that the inorganic glass bead thermal insulation mortar with a lower heat conductivity coefficient is obtained.
本发明提供了一种低导热系数的无机玻化微珠保温砂浆的组分配方，由如下重量份原料制成；原料组分及其质量百分比为：水泥45～63％，玻化微珠20～30％，建筑垃圾微粉5～10％；可再生乳胶粉0.75～1.2％，纤维素醚0.3～0.5％，淀粉接枝阴‑非离子型内养护剂2.0～2.5％，物料与水的比例为1.1:1；本发明还公开了无机玻化微珠保温砂浆的制备方法和设备。本发明的设备设计有刮板，能把搅拌罐内壁和底部的物料刮下，搅拌叶片设计成上下垂直的长条片状，并且与搅拌方向呈一定的夹角，这种设计不仅能使物料搅拌混合均匀，还可使物料沿搅拌叶片的表面滑动，避免搅拌叶片跟物料正面撞击，减小对球形封闭颗粒状的玻化微珠的破坏，从而获得较低导热系数的无机玻化微珠保温砂浆。
