Description

一种丙烯酸粉末涂料配方
技术领域
本发明涉及到一种的配方。
背景技术
粉末涂料是一种新型的不含溶剂100%固体粉末状涂料。具有无溶剂、无污染、可回收、环保、节省能源和资源、减轻劳动强度和涂膜机械强度高等特点。
目前， 热固型粉末涂料是以热固性树脂作为成膜物质，加入起交联反应的固化剂经加热后能形成不溶不熔的质地坚硬涂层，温度再高该涂层也不会像热塑性涂层那样软化，而只能发生分解，由于热固性粉末涂料所采用的树脂为聚合度较低的预聚物，分子量较低，所以涂层的流平性较好，具有较好的装饰性，而且低分子量的预聚物经固化后，能形成网状交联的大分子，因而涂层具有较好防腐性和机械性能，故热固性粉末涂料发展尤为迅速，但是，现有技术中，其粉末涂料由聚酯树脂、封闭型异佛尔铜二异氰酸酯、安息香和二丁基锡二月桂酸酯组成，其缺点为物理学性能差、覆盖效果较差，易产生细泡，无法满足电器喷涂和表层保护。
发明内容
本发明要解决的技术问题是克服上述不足，提供一种覆盖性能好、流平性较好，具有较好的装饰性的复合粉料配方。
为了解决上述技术问题，通过以下技术方案得以实施：
一种丙烯酸粉末涂料配方，所述混合涂料配方为对奔二甲醇1200-1494g，乙二醇130-146g，己二醇360-400g，环己烷二甲醇650-721g，三羟甲基丙烷46-54g，Sb2O3
0.3-0.5g。
所述三羟甲基丙烷中羟值为25-33mgKOH/g。
所述对奔二甲醇、乙二醇、己二醇和环己烷二甲醇在250℃反应，脱去反应水后加入。
所述三羟甲基丙烷和Sb2O3在真空下270℃反应4小时进行解聚。
采用如上技术方案后，其有益效果为：
采取上述配方后，经烘烤即可得到性能优异的涂膜表面，如涂膜的持久性，其中包括：耐磨擦性、冲击性、密着性、韧性、耐蚀性及耐化学药品性能等。而户外用的粉末涂料，除了上述的优点外，更包括了高耐候性及耐污染性。尤其是较厚的涂膜且流平性好，不会象溶剂涂料厚涂时会有滴垂或积滞等现象发生。因粉末涂料使用静电原理喷涂，涂装设备可达到全自动化，无须浪费人力资源，大多以其共聚物为主，以封闭型异氰酸酯作交联剂。
