Ceramsite expansion auxiliary agent and preparation method thereof
The invention relates to the technical field of ceramsite expansion aids, and discloses a ceramsite expansion aid. The ceramsite expansion aid is prepared from the following components in parts by weight: 10-20 parts of purified water, 0.3-0.5 part of industrial salt, 0.3-0.5 part of an emulsifier, 0.3-0.5 part of a plasticizer, 0.3-0.5 part of a water reducing agent and 78-88 parts of diluted asphalt. The industrial salt is composed of calcium carbonate, sodium carbonate and sodium bicarbonate, the plasticizer is prepared from acrylamide and carboxymethyl cellulose through graft copolymerization, and the water reducer is prepared from sodium methallyl sulfonate, 2-acrylamide-2-methylpropanesulfonic acid, methacrylic acid and methoxy polyethylene glycol through esterification reaction and polymerization reaction. The ceramsite prepared by the invention has the characteristics of small apparent density, good thermal insulation performance and low water absorption; the sound-absorbing and supporting brick is good in anti-permeability, high in compressive strength, small in strength loss, long in fire-resistant time and good in durability and freezing resistance in a high-temperature environment, and meanwhile has good sound-absorbing performance and supporting strength.
本发明涉及陶粒膨胀助剂技术领域，公开了一种陶粒膨胀助剂按重量份组成如下：10～20份净化水、0.3～0.5份工业盐、0.3～0.5份乳化剂、0.3～0.5份塑化剂、0.3～0.5份减水剂和78～88份稀释沥青。本发明中的工业盐由碳酸钙、碳酸钠和碳酸氢钠组成，塑化剂由丙烯酰胺和羧甲基纤维素进行接枝共聚反应制得，减水剂由甲基丙烯磺酸钠、2‑丙烯酰胺‑2‑甲基丙磺酸、甲基丙烯酸和甲氧基聚乙二醇通过酯化反应和聚合反应制得，由本发明制备的陶粒具有表观密度小，保温隔热性能好，吸水率低的特性；且抗渗性好，抗压强度高，在高温环境下，其强度损失较小，耐火时间长，耐久抗冻性好，同时具有良好的吸音性能和支撑强度。
