Anti-cracking gypsum-based light material
The invention relates to an anti-cracking gypsum-based light material. The anti-cracking gypsum-based light material comprises, by mass, 100 parts of building gypsum, 75 to 95 parts of water, 45 to 65parts of glass beads, 0.3 to 0.6 part of polyvinyl alcohol fibers, 8 to 15 parts of rubber particles, 0.2 to 0.6 part of a silane coupling agent, 0.2 to 0.6 part of an adhesive, 0.2 to 0.6 part of awater retaining agent, 0.2 to 0.6 part of a water reducing agent and 0.2 to 0.6 part of a retarder. The rubber particles with different particle sizes, the glass beads, the gypsum cementing material and the like are filled step by step according to a certain mass ratio, and besides grading optimization among multiple phases, in-phase particle grading optimization is further increased to improve the compatibility among the multiple phases in a matching manner. The gypsum-based light material which is low in dry density, excellent in deformation damage resistance and good in heat preservation and heat insulation performance is obtained by further combining the interaction of other auxiliary components.
本发明涉及一种抗裂型石膏基轻质材料，其原材料按质量份数计，包括以下组分：建筑石膏100份，水75‑95份，玻化微珠45‑65份，聚乙烯醇纤维0.3‑0.6份，橡胶颗粒8‑15份，硅烷偶联剂0.2‑0.6份，胶粘剂0.2‑0.6份，保水剂0.2‑0.6份，减水剂0.2‑0.6份和缓凝剂0.2‑0.6份。本发明以不同粒径大小的橡胶颗粒、玻化微珠以及石膏胶凝材料等按一定质量比例进行逐级填充，除了多相之间的级配优化，更增加了同相的颗粒级配优化以配合提高多相之间相容性。进一步结合其他助剂成分相互作用，得到干密度小，具有优异的抵抗变形破坏能力和良好的保温隔热性能的石膏基轻质材料。
