所述的AS树脂的重均分子量为3～10W，AN含量为20～35％，所述耐化学品改性剂为含氟类添加剂。The weight-average molecular weight of the AS resin is 3-10W, the AN content is 20-35%, and the chemical resistance modifier is a fluorine-containing additive.
其中，所述耐化学品改性剂为全氟烷基的丙烯酸系添加剂。Wherein, the chemical resistance modifier is a perfluoroalkyl acrylic additive.
其中，所述的光稳定剂为水杨酸酯、二苯甲酮、三嗪类、苯并三唑类的UV吸收剂以及受阻胺类自由基捕捉剂中的一种或多种混合物。Wherein, the light stabilizer is one or more mixtures of salicylates, benzophenones, triazines, benzotriazoles UV absorbers and hindered amine free radical scavengers.
其中，所述的红外反射二氧化钛粒径为1000nm-1300nm，TiO2含量为80％-90％，表面包覆层SiO2与Al2O3的含量为10-20％。Wherein, the particle size of the infrared reflective titanium dioxide is 1000nm-1300nm, the content of TiO 2 is 80%-90%, and the content of SiO 2 and Al 2 O 3 in the surface coating layer is 10-20%.
其中，所述的导热填料为氧化镁、氧化锌、氢氧化铝、氮化硼、氮化铝按质量比3∶2∶1∶3∶1混合所得，所述导热填料的粒径在0.5um-2.0um，纯度大于98％。Wherein, the thermally conductive filler is obtained by mixing magnesium oxide, zinc oxide, aluminum hydroxide, boron nitride, and aluminum nitride in a mass ratio of 3:2:1:3:1, and the particle size of the thermally conductive filler is 0.5um -2.0um, the purity is greater than 98%.
其中，所述热稳定剂为N-苯基马来酰亚胺的共聚物或α-甲基苯乙烯的共聚物。Wherein, the heat stabilizer is a copolymer of N-phenylmaleimide or a copolymer of α-methylstyrene.
其中，所述促进剂为二异丁基二硫代氨基甲酸锌和二丁基二硫代氨基甲酸按质量比2∶5混合所得。Wherein, the accelerator is obtained by mixing zinc diisobutyl dithiocarbamate and dibutyl dithiocarbamate at a mass ratio of 2:5.
其中，所述偶联剂为硅烷偶联剂。Wherein, the coupling agent is a silane coupling agent.
其中，所述其他助剂为亚磷酸酯类抗氧剂、乙撑双硬脂酸酰胺、分散剂、消泡剂、防冻剂和阻燃剂中的至少两种的混合物。Wherein, the other additives are a mixture of at least two of phosphite antioxidants, ethylene bisstearic acid amide, dispersants, defoamers, antifreeze agents and flame retardants.
本发明具有以下有益效果：The present invention has the following beneficial effects:
通过选用超低分子量的AS树脂，提高了流动性，降低了颜料干燥过程中产生的内应力，同时引入全氟烷基的丙烯酸系添加剂作为耐化学品改性剂，该添加剂的迁移效率极高，在制备过程中即可完全迁移到表面形成一种保护膜，这层保护膜和水不相容且具有较强的耐酸碱的性能，可以极大减少开裂情况，提高喷涂良率；通过偶联剂和促进剂的添加，可以使制备的颜料达到速干的性能；通过羧甲基纤维素、碳酸钙的添加，可以使颜料更加的细腻；选用硅烷偶联剂，可以使制备颜料的颜色保持更持久，不易褪色。采用红外反射钛白粉，可以大幅度反射太阳光的可见光和红外部分能量，加之导热填料的热释放的协同贡献，可以使较大幅度地降低涂料的表面温度。经实验发现，通过该方案提高涂料长期耐候性的效果是非常显著地，与预期是具有非常大的差距。By selecting ultra-low molecular weight AS resin, the fluidity is improved, and the internal stress generated during the drying process of the pigment is reduced. At the same time, a perfluoroalkyl acrylic additive is introduced as a chemical resistance modifier, and the migration efficiency of the additive is extremely high. , which can completely migrate to the surface to form a protective film during the preparation process. This protective film is incompatible with water and has strong acid and alkali resistance, which can greatly reduce cracking and improve spraying yield; through The addition of coupling agent and accelerator can make the prepared pigment achieve quick-drying performance; the addition of carboxymethyl cellulose and calcium carbonate can make the pigment more delicate; the selection of silane coupling agent can make the prepared pigment Color stays longer and doesn't fade easily. The use of infrared reflective titanium dioxide can greatly reflect the visible light and infrared energy of sunlight, and the synergistic contribution of heat release from thermal conductive fillers can greatly reduce the surface temperature of the coating. It has been found through experiments that the effect of improving the long-term weather resistance of coatings through this scheme is very significant, and there is a very large gap with expectations.
