一种环保型耐水洗防水剂及其制备方法
摘要：
本发明提供了一种环保型耐水洗防水剂及其制备方法，其特征在于所述防水剂包含一种超支化聚酯改性物，其分子式为：，其中A‑OH为三羟甲基丙烷与2,2‑二羟甲基丙酸反应制备的超支化聚酯，x+y≤A的羟基数，所述制备方法包括超支化聚酯制备、半加成产物LDI‑HEA制备、超支化聚酯的改性。本发明提供一种环保型耐水洗防水剂及其制备方法，其特有的多活性基团与网状结构，使该防水剂具有优异的防水效果与耐水洗性。
摘要（英）：

The invention provides an environment-friendly water washing resistant waterproof agent and a preparation method thereof. The waterproof agent is characterized by comprising a hyperbranched polyestermodified compound, and has the molecular formula as shown in the description, A-OH is a hyperbranched polyester prepared from trimethylolpropane and 2,2-dimethylolpropionic acid through reactions, andx+y is less than or equal to the hydroxyl number of A. The preparation method comprises the following steps: preparing the hyperbranched polyester, preparing a half-addition product LDI-HEA, and performing modification on the hyperbranched polyester. The invention provides the environment-friendly water washing resistant waterproof agent and the preparation method thereof, and due to specific multi-active groups and a net-shaped structure of the waterproof agent, the waterproof agent is excellent in waterproof effect and water washing resistance.
