摘要
为研究酚醛树脂对玻纤的浸润性能,更好地指导实际生产,考察了两种酚醛树脂和三种玻璃纤维。通过添加稀释剂和分散剂改变树脂体系的表面张力、粘度和树脂对玻纤的动态接触角,采用靶环试验测试了多种树脂体系对三种玻纤的浸润速率,筛选出浸润性能最好的树脂体系和玻璃纤维。研究表明,表面张力越低,粘度越小,树脂与玻纤的动态接触角越小,越有利于提高树脂对玻纤的浸润效果。
In order to study the wettability of phenolic resin to glass fiber and better guide the actual produc- tion, two kinds of phenolic resin and three kinds of glass fiber were investigated in this paper. The best resin and glass fiber was confirmed selected considering the surface tension, viscosity and dynamic contact angle through in- troducing diluents and dispersants, and combining the target test that determined the wetting rate of resin penetrating into glass fiber, respectively. The results show that the lower the surface tension was, the smaller the viscosity was, the smaller the dynamic contact angle between resin and glass fiber was, and the better the effect of the resin to glass fiber.
