Gypsum-based heat-conducting self-leveling mortar as well as preparation method and application thereof
The invention discloses gypsum-based heat-conducting self-leveling mortar as well as a preparation method and application thereof. Raw materials for preparing the gypsum-based heat-conducting self-leveling mortar comprises phosphogypsum, papermaking white mud and a heat-conducting material, and does not comprise cement. The preparation method comprises the following steps of: mixing the phosphogypsum with the papermaking white mud, performing calcining and ball-milling; and mixing the ball-milled phosphogypsum and papermaking white mud with the heat conducting material, aggregate, a retarder,a defoaming agent, a water retaining agent, a water reducing agent and redispersible latex powder. The gypsum-based heat-conducting self-leveling mortar provided by the invention has good fluidity andheat conductivity, can be used for gap filling and upper-layer covering of floor heating pipelines, greatly saves the raw material cost of a floor heating system, and realizes resource reutilizationof two solid wastes, i.e., the phosphogypsum and papermaking white mud.
一种石膏基导热自流平砂浆及其制备方法和应用。所述石膏基导热自流平砂浆的制备原料包括磷石膏、造纸白泥和导热材料，并且不包括水泥。所述制备方法包括：将所述磷石膏与所述造纸白泥混合，煅烧，球磨；以及将球磨后的磷石膏与造纸白泥与导热材料、骨料、缓凝剂、消泡剂、保水剂、减水剂和可再分散性乳胶粉混合。本申请石膏基导热自流平砂浆具有良好的流动性及导热性，能够用于地暖管道间隙填充及上层覆面，而且极大地节省了地暖系统的原料成本，实现了磷石膏和造纸白泥这两种固体废弃物的资源再利用。
