Polymer concrete gravel regulator and preparation method thereof
The invention relates to the technical field of building materials, in particular to a polymer concrete gravel regulator and a preparation method thereof. The polymer concrete gravel regulator comprises 40-70 parts of a polyurethane emulsion, 3-5 parts of polyvinyl alcohol, 1-3 parts of polycarboxylic acid cellulose, 3-8 parts of calcium silicate, 1-4 parts of limestone powder and 40-80 parts of water. The preparation method comprises the following steps: adding the polycarboxylic acid cellulose, the calcium silicate and the limestone powder into water, and uniformly stirring to obtain a mixed solution; adding polyvinyl alcohol into the mixed solution, heating to 95-98 DEG C, and cooling to room temperature after the polyvinyl alcohol is completely dissolved to obtain an intermediate solution; and adding the polyurethane emulsion into the intermediate solution, and uniformly mixing to obtain the polymer concrete gravel regulator. Under the condition of reducing the sand rate of the concrete, the compressive strength of the concrete can be enhanced, so that the use amount of sand in the concrete can be reduced.
本发明涉及建筑材料的技术领域，尤其是涉及一种聚合物类混凝土砂石调节剂及其制备方法。聚合物类混凝土砂石调节剂包括：聚氨酯乳液40‑70份，聚乙烯醇3‑5份，聚羧酸纤维素1‑3份，硅酸钙3‑8份，石灰岩粉1‑4份，水40‑80份。其制备方法包括：将聚羧酸纤维素、硅酸钙和石灰岩粉加入水中，搅拌均匀后，得到混合液；再将聚乙烯醇加入混合液中，加热至95‑98℃，待聚乙烯醇完全溶解后，降温至室温，得到中间液；再将聚氨酯乳液加入中间液中，混合均匀后，得到聚合物类混凝土砂石调节剂。本申请可以在减小混凝土砂率的情况下，还可以增强混凝土的抗压强度，从而可以减少混凝土中砂子的用量。
