Special cement-based self-leveling mortar for indoor floor heating and preparation method thereof
The invention relates to special cement-based self-leveling mortar for indoor floor heating and a preparation method thereof. The special cement-based self-leveling mortar is prepared by mixing powder and water according to the mass ratio of 1:(0.22-0.25), wherein the powder is prepared from the following components in parts by weight: cement, anhydrite, alpha semi-hydrated gypsum, 40-70-mesh heat-conducting filler, 70-140-mesh heat-conducting filler, 200-mesh heat-conducting filler, 500-mesh heat-conducting filler, heat-conducting soft metal wires with the length of 6mm, redispersible rubber powder, cellulose ether and the like. The invention overcomes the defects that: cement-based self-leveling needs to be used for leveling when the existing indoor floor heating is laid, however, no cement-based self-leveling special for floor heating exists in the market at present, common cement-based self-leveling is mostly used, the heat conductivity coefficient is low, the heat conduction rate is slow, the heat loss amount is large and the like. The method is based on special cement and Portland cement which cooperate with the heat-conducting filler with higher heat conductivity coefficient, the heat-conducting soft metal wire and other preferable additives, so that the mortar has the advantages of high heat conductivity coefficient, high heat-conducting rate and low heat-conducting loss.
本发明涉及一种室内地暖专用水泥基自流平砂浆及其制备方法，由粉料与水按照质量比1:0.22‑0.25的比例混合制备而成；其中，粉料由以下组分按照以下重量份数比制备而成：水泥、无水石膏、α半水石膏、40‑70目的导热填料、70‑140目导热填料、200目的导热填料、500目的导热填料、长度6mm的导热软金属丝、可再分散胶粉、纤维素醚等。该发明克服了现有室内地暖铺设时找平需要使用水泥基自流平，然而现有市面上没有地暖专用的水泥基自流平，多使用普通的水泥基自流平，存在导热系数低、导热速率慢、热损耗量大等缺点，以特种水泥、硅酸盐水泥为基础，配合导热系数较高的导热填料、导热软金属丝以及优选的其他添加剂，具有导热系数高、导热速率快、导热损耗量低的优点。
