Description
技术领域
本发明涉及涂料领域，具体涉及一种复合板材用装饰涂层浆料及其制备方法。
背景技术
随着工业化进程的加快以及对环境保护的重视，我国粉煤灰的综合利用在广度和深度上都得到了快速发展。其中，粉煤灰/树脂保温复合板材的开法应用研 究也逐渐得到认可。但由于粉煤灰自身存在颜色遮蔽困难、耐化学腐蚀性较差的不足，树脂也有硬度低、易燃等缺点，使得粉煤灰/树脂保温复合板材的各项性能难以平衡，或导致其开发成本较高。通过增加涂层的办法，可以将粉煤灰/树脂保温复合板材分成基体板材和表面涂层两个部分。在制备基体板材时，确保其具有足够强度的情况下，可以大幅度提高粉煤灰的用量，从而有效降低其成本。而复合板材的表面装饰性、耐环境性、耐划伤性以及阻燃性，主要由表面涂层来保障。通过 “基体板材+表面涂层”的方式，是开发出粉煤灰利用率高、成本低廉且集保温性与装饰性于一体的粉煤灰 /树脂保温装饰复合板材的有效途径。
发明内容
本发明目的在于，提供一种附着力好，阻燃性高，综合性能佳的复合板材用装饰涂层浆料，本发明采用的技术方案如下：
一种复合板材用装饰涂层浆料，其特征在于，由以下组分按重量百分比混合制备而成：
环氧树脂 35-65份
丙酮 5-10份
乙二胺 3-8份
颜料 2-5份
粉煤灰 10-20份
聚四氟乙烯 2-5份
氢氧化铝 20-50份。
作为优选方案之一，所述的环氧树脂是由E-44环氧树脂与E-51环氧树脂按照重量份为1:1混合组成。
作为优选方案之一，所述的粉煤灰是经过硅烷偶联剂表面改性。
作为优选方案之一，所述的粉煤灰为200目。
其中，制备上述的复合板材用装饰涂层浆料的步骤如下：
（1）按照配方称取一定量的环氧树脂，丙酮，加热使环氧树脂充分溶解，冷却至室温后加入乙二胺并搅拌均匀；
（2）往步骤（1）中加入改性后的粉煤灰，聚四氟乙烯，氢氧化铝，颜料等充分搅拌均匀；
（3）加入适量丙酮，调节到合适的黏度，即得涂层浆料。
本发明相对于现有技术的有益效果是：本发明通过科学选材，合理搭配，选用两种不同的环氧树脂混合搭配使用，有效保证涂层与基体板材的附着力。通过添加氢氧化铝与粉煤灰，有效降低了涂层的成本以及提高涂层的阻燃性。添加聚四氟乙烯进一步提高涂层的阻燃性和耐腐蚀性，使得涂层综合性能达到最佳。
