随着溶剂型涂料对环境的不友好性加剧，作为替代型竞品，越来越多不同类型的粉末涂料由于无VOC且易回收的优点正逐渐取代溶剂型涂料，以纯聚酯型、环氧/聚酯型为代表的粉末涂料也在家居、工业等领域中占据越来越重要的位置。As solvent-based coatings become more unfriendly to the environment, as alternative competing products, more and more different types of powder coatings are gradually replacing solvent-based coatings due to their VOC-free and easy-to-recycle advantages. Powder coatings represented by polyester type are also occupying an increasingly important position in the fields of household and industry.
然而，与传统的溶剂型涂料相同，即便是粉末涂料，也面临着在某些场景下容易被损坏、被腐蚀、寿命较短的使用隐患，从而危及到内层材料甚至是关键机动部位的正常运行。不同领域的应用都对粉末涂料的耐候性和耐腐蚀性提出了较高的要求，越来越多的人也在尝试添加填料、改进粉料结构、使用生物基材料(如竹、麦秆、麻、椰壳纤维等)制备复合聚酯材料等方法来增强材料的功能性，然而这些方法或多或少地都会以牺牲材料本身的强度、冲击性能等为代价。However, like traditional solvent-based coatings, even powder coatings face hidden dangers of being easily damaged, corroded, and short-lived in certain scenarios, thus jeopardizing the inner layer materials and even the normal operation of key motorized parts. run. Applications in different fields have put forward higher requirements for the weather resistance and corrosion resistance of powder coatings. More and more people are also trying to add fillers, improve the powder structure, and use bio-based materials (such as bamboo, wheat straw, However, these methods will more or less sacrifice the strength and impact performance of the material itself.
本发明利用多种类且价格低廉的饱和/不饱和聚酯固化的网络结构，辅以少量丙烯酸树脂“冷拼”，再利用高纯玻璃纤维粉和云母、蒙脱土、高岭土等黏土矿物填料来赋予聚酯型粉末涂料更健全持久的性能，在低成本、加工简便的基础上使涂料兼具包括高强度、自修复功能等多种性能，在保证涂层强度的基础上避免聚酯等粉末涂料“一撞就裂”的尴尬场景。The present invention utilizes a variety of low-cost saturated/unsaturated polyester-cured network structures, supplemented by a small amount of acrylic resin "cold blending", and then utilizes high-purity glass fiber powder and clay mineral fillers such as mica, montmorillonite, kaolin, etc. Endows polyester powder coatings with more robust and lasting performance, and enables the coatings to have multiple properties including high strength and self-healing functions on the basis of low cost and easy processing, and avoids polyester and other powders on the basis of ensuring coating strength. The embarrassing scene where the paint "cracks as soon as it hits".

有益效果：Beneficial effects:
本发明解决一般粉末涂料板面耐候性、防腐蚀性不佳的问题主要从两个角度：The invention solves the problems of poor weather resistance and corrosion resistance of general powder coating panels mainly from two angles:
首先，通过R型二氧化钛的紫外线屏蔽作用、蒙脱土的气体阻隔作用及尺寸稳定性等物理层面隔绝外界条件的干扰；再加上少量高岭土的加入，其扁平性质可以有效阻隔水分或者酸碱液的渗透，使得涂膜耐洗刷性和抗污染性得到改善，除此之外，高岭土的化学惰性较强，晶体光轴角小，晶体排列的有序度较高，也会屏蔽部分紫外线。以上填料的加入都降低了材料板面与外界可能导致腐蚀的条件接触的机会，某种程度上也提升了板面的耐腐蚀性；另外，从材料本身而言，饱和/不饱和聚酯/少量丙烯酸酯之间的交联结构使涂料形成了很致密的三维网络结构，且不饱和聚酯的存在以及增强材料玻纤的存在会使得涂层体系强度高、耐热性好、具有优异的耐化学腐蚀性能及电性能，外界强酸碱环境或强烈日照也难以渗透。少量丙烯酸酯的存在也使得涂层和被涂物表面接触地更加紧密，不易出现局部剥离、脱落等现象。First of all, through the ultraviolet shielding effect of R-type titanium dioxide, the gas barrier effect of montmorillonite, and the dimensional stability and other physical aspects to isolate the interference of external conditions; coupled with the addition of a small amount of kaolin, its flat nature can effectively block moisture or acid and alkali liquids In addition, the chemical inertness of kaolin is strong, the crystal optical axis angle is small, the crystal arrangement has a high degree of order, and it also shields some ultraviolet rays. The addition of the above fillers reduces the chance of contact between the material surface and the external conditions that may cause corrosion, and also improves the corrosion resistance of the surface to a certain extent; in addition, from the material itself, saturated/unsaturated polyester/ The cross-linked structure between a small amount of acrylates makes the coating form a very dense three-dimensional network structure, and the existence of unsaturated polyester and the existence of reinforcing material glass fiber will make the coating system have high strength, good heat resistance, and excellent performance. Chemical corrosion resistance and electrical properties, it is difficult to penetrate the external strong acid and alkali environment or strong sunlight. The presence of a small amount of acrylate also makes the coating and the surface to be coated more closely contacted, and local peeling and falling off are not easy to occur.
再由于体系内存在较多的聚乙烯蜡及有助于流平作用的具有扁平性质的高岭土等成分的存在，加上涂层内部含有大量的酯基基团，伴随着催化剂如乙酰丙酮锌等的始终存在，可逆的酯基交换反应也有相当的概率能够发生，当板面发生局部损伤时，即便是微量的蜡成分及高岭土向凹痕处循序渐进的滑移在一段时间后也可以获得一定的修复效果，并且这种现象在给予加热条件的时候会变得尤为明显，包括流平过程及可逆的键交换反应，二者均能获得一定的修复效果。In addition, due to the presence of more polyethylene wax and kaolin clay with flat properties in the system, and the presence of a large number of ester groups in the coating, accompanied by catalysts such as zinc acetylacetonate, etc. It always exists, and the reversible transesterification reaction also has a considerable probability to occur. When local damage occurs on the board surface, even a small amount of wax components and kaolin slip gradually to the dent can obtain a certain amount of time after a period of time. Repair effect, and this phenomenon will become especially obvious when heating conditions are given, including leveling process and reversible bond exchange reaction, both of which can achieve a certain repair effect.
综上，通过交联结构的复杂化和多种填料的加入有效改进了该聚酯粉末涂料的耐候、抗腐蚀能力。To sum up, the weather resistance and corrosion resistance of the polyester powder coating are effectively improved through the complication of the cross-linked structure and the addition of various fillers.
