High-viscosity polyurethane cement mortar and preparation method thereof
The invention discloses high-viscosity polyurethane cement mortar and a preparation method thereof. The high-viscosity polyurethane cement mortar comprises a part A and a part B, the part A comprises the following components: cement, silica fume, sand, a functional additive and fibers, and the part B comprises the following components: waterborne polyurethane and water. And the strength grade of the polyurethane cement mortar is 52.5. The preparation method of the mortar comprises the following steps: preparing the materials, weighing the components according to the proportion, putting the components into a stirrer, uniformly stirring to obtain the part A and the part B respectively, and uniformly stirring the part A and the part B according to the proportion to obtain the high-viscosity polyurethane cement mortar. The obtained polyurethane cement mortar has the characteristics of high bonding strength, good toughness, easiness in operation, excellent curing performance, low cost and the like, and is matched with a carbon fiber grid reinforcing system for use, so that the interface shear force between the mortar and a carbon fiber grid is remarkably improved.
本发明公开了一种高粘度聚氨酯水泥砂浆及其制备方法。高粘度聚氨酯水泥砂浆，包括A和B两个部分。A部分包括以下组分：水泥、硅灰、砂、功能性添加剂、纤维，B部分包括以下组分：水性聚氨酯、水。所述聚氨酯水泥砂浆的强度等级为52.5。该砂浆的制备方法为：准备材料，按比例称取各组分，将各组分放到搅拌器中搅拌均匀，分别得到A部分和B部分，将A部分和B部分按照比例搅拌均匀，即可得到高粘度聚氨酯水泥砂浆。本发明得到的聚氨酯水泥砂浆具有粘结强度高、韧性好、易操作、固化性能优异、成本低廉等特点，与碳纤维网格加固系统配套使用，显著提高砂浆与碳纤维网格之间的界面剪切力。
