Novel cement adhesive for electrical porcelain
The invention discloses a novel cement adhesive for electric porcelain, and belongs to the technical field of electric porcelain. The invention relates to a novel cement adhesive for electrical porcelain, which comprises the following raw materials by weight: 40-55% of Portland cement; 35-45% of quartz sand; 0.4 to 0.6 percent of a modified polycarboxylic acid water reducing agent; 0.1%-0.3% of a defoaming agent; and 9-15% of water. The modified polycarboxylate superplasticizer prepared in the invention has excellent dispersion performance, and the adsorption capacity with the surfaces of cement particles is greatly improved; and the prepared cement adhesive has the advantages of relatively high early strength and sufficient later strength, and also has very high breaking strength and compressive strength.
本发明公开了一种电瓷新型水泥胶合剂，属于电瓷技术领域。一种电瓷新型水泥胶合剂，按重量百分比计，包括如下原料：硅酸盐水泥：40‑55％；石英砂：35‑45％；改性聚羧酸减水剂：0.4‑0.6％；消泡剂：0.1‑0.3％；水：9‑15％。其中本发明中所制备的改性聚羧酸减水剂，分散性能优异，并且大幅度提高与水泥颗粒表面的吸附量；增强了水泥胶合剂的耐久性能，且制备出的水泥胶合剂具有前期强度较高，后期强度充足的优点，同时具有很高的抗折强度和抗压强度。
