一种用于风力叶片的耐候型弹性聚氨酯腻子的配制方法
摘要：
本发明涉及一种用于风力叶片的耐候型弹性聚氨酯腻子的配制方法，主要包括首先将能与异氰酸根反应的高柔韧性的无溶剂树脂10～50份，以及能与异氰酸根反应的高硬度的无溶剂树脂3～30份共同在搅拌缸中混合均匀，然后在30℃～70℃温度下反应0.5～5小时；在反应完毕后依次加入金红石型钛白粉取10～50份、无机填料10～50份、分散剂0.2～1.5份、消泡剂0.1～0.5份、流变助剂0.1～1.5份，分散研磨至100微米以下，再用色浆调色包装；取固化剂与催化剂与制剂混合。本发明有益效果为：具有良好的耐候性、干燥时间可调整性、弹性较佳等特点；此外，还具有防止低温开裂的特点。
摘要（英）：

The invention relates to a preparation method of weather-resistant elastic polyurethane putty for a wind blade, mainly comprising the following steps: firstly, uniformly mixing 10-50 parts of high-flexibility solvent-free resin capable of reacting with isocyanato and 3-30 parts of high-hardness solvent-free resin capable of reacting with the isocyanato in a stirring tank, and then reacting at the temperature of 30-70 DEG C for 0.5-5 hours; after the reaction is finished, sequentially adding 10-50 parts of rutile titanium white powder, 10-50 parts of inorganic filler, 0.2-1.5 parts of dispersing agent, 0.1-0.5 parts of defoaming agent and 0.1-1.5 parts of rheological agent, dispersing and grinding to be smaller than 100 micrometers, and then mixing the color by using color paste; and mixing curing agent, catalyst and preparation. The preparation method has the beneficial effects that the weather-resistant elastic polyurethane putty has the characteristics of favorable weather resistance, adjustable drying time, better elasticity and the like; and in addition, the weather-resistant elastic polyurethane putty has the characteristic of preventing cracking at low temperature.
