Epoxy resin with low linear thermal expansion coefficient, preparation method thereof and epoxy mortar
The invention provides epoxy resin with a low linear thermal expansion coefficient, a preparation method of the epoxy resin and epoxy mortar. The epoxy resin with the low linear thermal expansion coefficient is prepared from the following raw materials in parts by weight: 80-100 parts of epoxy resin, 8-20 parts of a reactive diluent, 0.1-0.5 part of a defoaming agent, 10-25 parts of a curing agent, 0-5 parts of an accelerant and 5-15 parts of modified aromatic oxadiazole resin. The epoxy resin with the low linear thermal expansion coefficient has relatively high crosslinking density, rigidity and polarity, so that the cured epoxy resin is relatively low in linear thermal expansion coefficient, also has relatively low initial viscosity and is convenient to construct. By adopting the epoxy mortar prepared by the invention, the problems of hollowing, falling, cracking and the like caused by temperature change can be effectively reduced.
本发明提供了一种低线性热膨胀系数环氧树脂及其制备方法、环氧砂浆，该低线性热膨胀系数环氧树脂的制备原料包括按重量份计的以下成分：环氧树脂80‑100份、活性稀释剂8‑20份、消泡剂0.1‑0.5份、固化剂10‑25份、促进剂0‑5份，改性聚芳噁二唑树脂5‑15份。本发明的低线性热膨胀系数环氧树脂具有较高的交联密度、刚性和极性，使固化后环氧树脂线性热膨胀系数较低，还具有较低的初始粘度，施工方便。采用本发明制备的环氧砂浆可以有效减少因温度变化引起的空鼓、脱落和开裂等问题。
