卷材涂料用水性丙烯酸树脂的制备及其性能研究 总被引:1,自引:0,他引:1
采用溶剂法,以BPO为引发剂,单体滴加的方式合成了一系列水性丙烯酸树脂。通过FTIR、DSC和GPC测试表明:所合成树脂的化学结构与预期结构相一致,反应温度对树脂相对分子质量及其分布影响很大,同时影响E10的接枝方式。用所合成的水性丙烯酸树脂制备的水性丙烯酸卷材涂料与普通溶剂型卷材涂料的常规性能相当。 相似文献

聚合方法对水性羟基丙烯酸树脂及相应2K-WPU性能的影响 总被引:1,自引:0,他引:1
分别通过溶液聚合、乳液聚合和两步聚合法制备了3种水性羟基丙烯酸树脂(PAS、PAE、PAT),采用傅里叶变换红外光谱(FT-IR)、动态光散射(DLS)和示差扫描量热法(DSC)对所合成树脂进行了表征。在无催化剂存在的条件下,分别将3种水性树脂与异氰酸酯固化剂Bayhydur XP 2655以及助剂混合得到双组分水性聚氨酯清漆,通过红外光谱对固化后清漆结构进行了表征,并对3种水性清漆的性能进行了研究。实验结果表明基于PAT的水性清漆综合性能较优。 相似文献

UV curable glycidyl carbamate based resins 总被引:1,自引:0,他引:1
The synthesis and characterization of UV curable resins based on glycidyl carbamate chemistry have been explored. Glycidyl carbamate (GC) functional resins have been used to obtain crosslinked coatings with a wide range of properties using several crosslinking techniques such as epoxy-amine, self-crosslinking, and sol-gel. GC resin technology was further expanded to UV curable coatings by reacting polyfunctional GC resins with acrylic acid to yield acrylated glycidyl carbamate (AGC) resins. Alcohol-modified UV curable GC resins were also prepared to obtain lower viscosity. Commonly used reactive diluents were used to prepare a UV curable GC coating formulations. The coatings were cured in air using a Fusion LC6B Benchtop Conveyer with an F300 UV lamp. The degree of conversion of acrylic double bonds during UV curing was determined using real time FTIR and showed that the resins had fast cure rates and high extents of conversion of acrylate groups. Coating properties such as hardness, impact strength, methyl ethyl ketone double rubs, flexibility, and adhesion were studied. Dynamic mechanical analysis was used to determine crosslink density of the coatings. Differential scanning calorimetry and thermogravimetric analysis were used to study the thermal properties of the coatings. The type of polyisocyanates and the extent of modification in GC resins influenced the degree of conversion, crosslink density, and coating performance. 相似文献
