Basalt-toughened color-altered durable polyurethane concrete and preparation process thereof
The invention provides basalt-toughened color-altered durable polyurethane concrete, which is prepared from the following components in parts by mass: 400 parts of isocyanate, 500 parts of combined polyether polyol, 6000 parts of graded quartz sand, 1500 parts of 4 white cement, 500 parts of fly ash, 500 parts of ferric oxide color material, 150 parts of basalt fiber, 1 part of catalyst and 20 parts of molecular sieve. The preparation process of the durable polyurethane concrete toughened and modified in color by utilizing basalt comprises the following steps: S1, drying part of raw materials to an anhydrous state, and uniformly stirring; s2, adding a catalyst into the dried combined polyether polyol, stirring and mixing, adding the mixture into the aggregate mixture obtained in the S1, and adding the dried basalt fibers in the stirring process; and S3, adding isocyanate, uniformly stirring, pouring into a mold, standing for 24 hours, and demolding to obtain the toughened color-modified durable polyurethane concrete. The structure has the advantages of being high in stability and durability and low in cost.
本专利提供了本发明一种利用玄武岩增韧改色耐久型聚氨酯混凝土，按照质量份数包括以下组分，异氰酸酯400份、组合聚醚多元醇500份等级配石英砂6000份、4白水泥1500份、粉煤灰500份、氧化铁系颜色材料500份、玄武岩纤维150份、催化剂1份和分子筛20份；一种利用玄武岩增韧改色耐久型聚氨酯混凝土的制备工艺，包括以下步骤：S1、将部分原料烘干至无水状态，搅拌均匀；S2、将催化剂加入到烘干后组合聚醚多元醇中，搅拌混合，将其加入S1所得的骨料混合物中，在搅拌过程中加入烘干后的玄武岩纤维；S3、加入异氰酸酯，搅拌均匀，倒入模具中，静置24h脱模，得到增韧改色耐久型聚氨酯混凝土；其优点在于：结构的稳定性和耐久性强，成本低。
