Description

一种斑纹效果的美术型粉末涂料及其制备方法
技术领域
本发明属于粉末涂料的制备领域，具体涉及一种斑纹效果的美术型粉末涂料及其制备方法。
背景技术
美术型粉末涂料是粉末涂料的重要品种之一，目前美术型粉末涂料主要有砂皱、橘纹、锤纹、浮花、闪光、金属色等种类，其中斑纹粉末涂料则以优选的外观视感、突出的凹凸触感、优异的物理机械性能以及良好的遮盖效果不断获得人们的青睐。
然而在斑纹粉末涂料的应用中发现，斑纹涂膜还存在明显的抹擦掉色现象，这是由于纹理颜料与基料树脂润湿先天不足造成的，即使是采用热混工艺生产的产品也无法消除。
发明内容
本发明的目的在于针对现有技术的不足，提供一种斑纹效果的美术型粉末涂料及其制备方法。该粉末涂料由以环氧树脂/端羧基聚酯树脂为主要原料的A组分以及以端羟基聚酯树脂为主要原料的B组分通过热粘合工艺制成，对原料之间的配比进行了优选，提高了原料之间的分散性，耐候性好，附着力明显提高，明显降低了涂层擦拭时的颜料颗粒脱落现象，产品质量品质得到全面提升。
为实现上述目的，本发明采用如下技术方案：
一种斑纹效果的美术型粉末涂料，由A粉、B粉和珠光粉按重量比90:5:5混合制得；
所述的A粉由以下原料组成：环氧树脂40wt%，端羧基聚酯树脂40wt%，沉淀硫酸钡5wt%，醋酸丁酸纤维素0.2wt%，钛白粉14wt%，炭黑0.8wt%；
所述的B粉由以下原料组成：端羟基聚酯树脂90wt%，颜料5wt%，聚醚聚合物5wt%。
所述聚醚聚合物为聚氧化丙烯二醇或聚氧乙烯中的一种。
一种制备如上所述的斑纹效果的美术型粉末涂料的方法，包括以下步骤：
1）将环氧树脂、端羧基聚酯树脂、沉淀硫酸钡、醋酸丁酸纤维素、钛白粉和炭黑经混合、挤出、压片破碎、磨粉筛分，制得A粉；
2）将端羟基聚酯树脂、颜料和聚醚聚合物经混合、挤出、压片破碎、磨粉筛分，制得B粉；
3）将A粉、B粉和珠光粉按重量比加入混合机中，进行干混、热粘合（55℃）处理，当粘结过程完成时，经高速混合均匀后立即出料、筛分。
本发明的有益效果在于：
1）该粉末涂料由以环氧树脂/端羧基聚酯树脂为主要原料的A组分以及以端羟基聚酯树脂为主要原料的B组分通过热粘合工艺制成，提高了原料之间的分散性，耐候性好，附着力明显提高，明显降低了涂层擦拭时的颜料颗粒脱落现象，产品质量品质得到全面提升；
2）本发明对该粉末涂料原料的配方进行了反复研究，最终确定了最佳配比，在该配比上，粉末涂料在应用时，凹凸触感突出，耐候性好，附着力明显比其他配比时高，经擦拭测试时完全没有抹擦掉色现象；而当改变配比时，均有一定程度的少量抹擦掉色现象。
具体实施方式
本发明用下列实施例来进一步说明本发明，但本发明的保护范围并不限于下列实施例。
