Preparation method of low-temperature-resistant adhesive for porcelain insulator
The invention discloses a preparation method of a low-temperature-resistant adhesive for a porcelain insulator, and the low-temperature-resistant adhesive comprises the following raw materials in parts by weight: Portland cement of 525 # or above, cemented composite sand, fibers, water, a solid water reducing agent, Jieban metakaolin and an additive. The preparation method comprises the followingsteps: A, sequentially pouring the Portland cement, the cementing composite sand, the fibers and the Jieban metakaolin into a stirrer in proportion, and uniformly mixing and stirring; B, proportionally adding the solid water reducing agent and the additive into a stirrer, gradually adding water, sufficiently stirring, taking out, and immediately molding; C, placing in a curing room for demolding after molding; and D, placing the demoulding test body on a curing frame of a curing room, spraying water three times a day, and covering with breathable curing cloth until the cement adhesive is completely cured. The early strength is rapidly improved, bubbles are reduced, and the low-temperature expansion characteristic of the cement adhesive is inhibited.
本发明公开了一种瓷绝缘子用耐低温胶合剂的制备方法，所述耐低温胶合剂包括以下重量份原料：525#以上的硅酸盐水泥，胶装复合砂，纤维，水，固体减水剂，界牌偏高岭土，外加剂，并按以下步骤制成：A、先将硅酸盐水泥、胶装复合砂、纤维、界牌偏高岭土按比例依次倒入搅拌机内混合搅拌均匀；B、然后按比例将固体减水剂、外加剂加入搅拌机，逐渐加水充分搅拌取出后立即成型；C、成型后置于养护房脱模；D、脱模试体置于在养护房的养护架上，每天喷水三次，并用透气养护布覆盖直至水泥胶合剂完全固化为止。本发明迅速提高了早期强度，减少了气泡，抑制了水泥胶合剂的低温膨胀特性。
