Color-adjustable graded polyurethane concrete rapid repairing material for bridge deck repairing
The invention provides a color-adjustable polyurethane concrete rapid repair material for bridge deck repair. The color-adjustable polyurethane concrete rapid repair material comprises the following components in parts by mass: 1-3 parts of a catalyst, 1000 parts of a component A, 20 parts of a molecular sieve, 6000 parts of graded quartz sand, 2000 parts of a color matching material and 400 parts of a component B, the invention relates to a preparation method of a color-adjustable polyurethane concrete rapid repairing material for bridge deck repairing. The preparation method comprises the following steps: S1, drying all materials to an anhydrous state; s2, 1000 parts of the component A and 1-3 parts of a tertiary amine catalyst are mixed; s3, 20 parts of molecular sieves, 6000 parts of graded quartz sand, 1000 parts of sand and 2000 parts of color matching materials are mixed and stirred; s4, mixing and stirring the mixture of the component A and the catalyst with the dry material mixture obtained in S3; and S5, adding 400 parts of a component B into the mixture obtained in S4, fully stirring, and pouring into a mold. The method has the advantages that the problem of color difference between a repaired part and an original bridge floor can be solved, and the method has various good performance indexes adapting to heavy load and is economical and practical.
本专利提供了一种桥面修补可调色聚氨酯混凝土快速修补材料，按照质量份数包括以下组分：催化剂1‑3份，A组分1000份，分子筛20份，等级配石英砂6000份，调色材料2000份，B组分400份；一种桥面修补可调色聚氨酯混凝土快速修补材料的制备方法，包括以下步骤：S1、将所有材料烘干至无水状态；S2、将A组分1000份和叔胺类催化剂1‑3份进行混合；S3、将分子筛20份，等级配石英砂6000份、沙子1000份，调色材料2000份进行混合并搅拌；S4、将A组分和催化剂的混合物与S3得到的干料混合物混合搅拌；S5、向S4所得混合物中加入B组分400份，充分搅拌之后倒入模具中。其优点在于：可以解决修补部分与原桥面的颜色差异问题，兼具适应重载的各项良好性能指标且经济实用。
