Production process of polyurethane anti-flaming waterproof coiled material

The invention discloses a production process of a polyurethane anti-flaming waterproof coiled material. The production process comprises the following steps of (1) material mixing; (2) primary dust removal; (3) primary drying; (4) coloring; (5) secondary drying; (6) waterproof layer coating; (7) third drying; (8) material coating; (9) fourth drying; (10) spinning; and (11) winding and packaging. According to the production process, the problem that the waterproof layer and a polyurethane anti-flaming layer are prone to falling off in the process of using of the waterproof coiled material is solved, and meanwhile when impurities appear on the surface of cloth during coating of the cloth, the solving of the problem of uniformity of a coating can be affected. 本发明公开了一种聚氨酯阻燃防水卷材生产工艺，包括以下步骤：（1）混合材料；（2）一次除尘；（3）一次烘干；（4）上色；（5）二次烘干；（6）涂抹防水层；（7）三次烘干；（8）涂抹材料；（9）四次烘干；（10）纺织；（11）收卷包装，通过以上步骤，解决了防水卷材在使用的过程中，容易出现防水层与聚氨酯阻燃层出现脱落的现象的问题，同时对在对布料进行涂料时，当布料表面出现杂质时，会影响到涂层的均匀度的问题进行解决。
