Polymer repairing mortar for rapidly repairing pavement and preparation method thereof
The invention discloses polymer repair mortar for quickly repairing a pavement and a preparation method thereof, and particularly relates to the field of pavement repair, the mortar is prepared from the following raw material components in parts by mass: 500 parts of cement, 1700 parts of sand, 20 parts of resin, 100 parts of water, 150 parts of curing agent, 90 parts of diluent and 20 parts of accelerant, and the index of the resin is that the appearance is colorless transparent viscous liquid; the epoxy value eq/100g is 0.48 to 0.53; the inorganic chlorine value eq/100g is 0.03; the organic chlorine value eq/100g is 0.01; volatile matter% < = 1; the color number is not more than 2; the viscosity of 40 DEG C mPa.s is less than or equal to 2500, and the cement index is early strength Portland cement of grade 42.5; wherein the fineness modulus mu of the sand in the cement is 0.3. According to the polymer repair mortar added with the active resin diluent and the polyamide curing agent, the adhesive force of epoxy resin is fully utilized, so that the bonding strength of the polymer repair mortar and old concrete is 9-10 times higher than that of ordinary cement mortar, and the polymer repair mortar has good toughness.
本发明公开了一种快速修复路面的聚合物修补砂浆及其制备方法，具体涉及路面修复领域，包括该砂浆的制备原料组分及质量配合比为：水泥500份，砂1700份，树脂20份，水100份，固化剂150份，稀释剂90份，促进剂20份，树脂指标为：外观为无色透明粘稠液体；环氧值eq/100g为0.48‑0.53；无机氯值eq/100g为0.03；有机氯值eq/100g为0.01；挥发物％≤1；色泽号≤2；粘度40℃mPa·s≤2500，水泥的指标为：42.5级的早强硅酸盐水泥；其中水泥中砂的细度模数μ＝0.3。添加活性树脂稀释剂和聚酰胺类固化剂的聚合物修补砂浆，这种配方充分利用了环氧树脂的粘结力，使得其与老混凝土的粘结强度高于普通水泥砂浆9～10倍，并且具有良好的韧性。
