High-performance gypsum self-leveling for floor heating backfilling
The invention discloses a high-performance gypsum self-leveling material for floor heating backfilling. The heat-conducting gypsum mortar is prepared from the following components in parts by weight: 10-16 parts of gypsum powder, 2-10 parts of heat-conducting filler, 7-8 parts of aggregate, 1-2 parts of a defoaming agent, 3-5 parts of a reinforcing agent, 4-6 parts of a water reducing agent, 2-3 parts of a retarder, 5-10 parts of functional fibers, 4-8 parts of rubber powder, 4-8 parts of a dispersing agent, 5-14 parts of sand and 3-8 parts of hydroxypropyl methyl cellulose. Through the arrangement of the heat-conducting mortar layer and the cement self-leveling mortar layer, the self-leveling performance of gypsum can be improved, the heat-conducting mortar layer and the cement self-leveling mortar layer are combined through an interface agent, the binding force is high, the self characteristics are kept, the hollowing effect is not prone to occurring, the laying structure of the cement self-leveling mortar layer is changed to avoid cracks, functional resin is added, and the heat-conducting mortar layer and the cement self-leveling mortar layer are not prone to cracking. Resin with different functions can be blended according to the condition of a laying site, so that the subsequent gypsum self-leveling performance is improved, and the condition of mildewing during subsequent gypsum self-leveling is also avoided due to the arrangement of the mildew preventive.
本发明公开了一种用于地暖回填的高性能石膏自流平，本发明包括其按重量份计由如下组份制成石膏粉10‑16份、导热填料2‑10份、骨料7‑8份、消泡剂1‑2份、增强剂3‑5份、减水剂4‑6份、缓凝剂2‑3份、功能纤维5‑10份、胶粉4‑8份、分散剂4‑8份、砂5‑14份、羟丙基甲基纤维素3‑8份。本发明通过导热砂浆层和水泥自流平砂浆层的设置可以在提高石膏自流平的性能，两者用界面剂结合，结合力高，保持自身的特性，并且不易发生空鼓效果，改变水泥自流平砂浆层的铺设结构来避免产生裂缝，并且增加有功能树脂，可以根据铺设地点的情况对进行调配不同功能树脂，进而提高了后续石膏自流平的性能，而防霉剂的设置也避免了后续石膏自流平出现发霉的情况发生。
