Special binder for microcrystalline glass
The invention relates to the field of building materials, in particular to a special binder for microcrystalline glass. The special binder for the microcrystalline glass comprises alpha-type high-strength gypsum, tailing sand and a volume stabilizer, wherein the alpha-type high-strength gypsum is prepared by dissolving and recrystallizing industrial byproduct gypsum in a saturated steam medium; the volume stabilizer is a mixture of a swelling reducing agent and a shrinkage reducing agent; the swelling reducing agent is tartaric acid; the shrinkage reducing agent is II type anhydrous anhydrite;the mass ratio of the alpha-type high-strength gypsum to the tailing sand to the volume stabilizer is (30-50):(50-70):(1-3). The special binder for the microcrystalline glass is neutral in pH value,has good compatibility with the microcrystalline glass, and is particularly suitable for masonry and bonding of the microcrystalline glass. Compared with binders in the prior art, the special binder is high in strength development speed, high in construction efficiency, high in bonding strength, not prone to falling off, good in size stability and not prone to hollowing. The cost is lower.
本发明涉及建筑材料领域，尤其涉及一种微晶玻璃专用粘结剂；所述微晶玻璃专用粘结剂包括α型高强石膏、尾矿砂、体积稳定剂；其中，α型高强石膏由工业副产石膏在饱和水蒸气介质中经溶解和重结晶制得；所述体积稳定剂为减膨剂和减缩剂的混合物；所述减膨剂为酒石酸；所述减缩剂为Ⅱ型无水硬石膏；所述α型高强石膏、所述尾矿砂与所述体积稳定剂的质量比为30～50：50～70：1～3。本发明的微晶玻璃专用粘结剂的pH值呈中性，与微晶玻璃具有很好的相容性，尤其适用于微晶玻璃的砌筑和粘结；所述微晶玻璃专用粘结剂相对于现有技术中的粘结剂强度发展速度快、施工效率高，粘结强度高、不易脱落，尺寸稳定性好、不易产生空鼓；并且成本较低。
