Description

一种纯环氧无光粉末涂料及其生产工艺
技术领域
本发明涉及粉末涂料及其生产工艺,特别是纯环氧无光粉末涂料及其生产工艺。
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。粉末涂料具有以下特性:
(1)不含毒性,不含溶剂和不含挥发有毒性的物质,故无中毒、无火灾、无“三废”的排放等公害的问题,完全符合国家环保法的要求。
   (2)原材料利用率高,一些知名品牌的粉末供应商生产的粉末,其过喷的粉末可回收利用,最高的利用率甚至能达99%以上。
   (3)一次性施工,无需底涂,即可得到足够厚度的涂膜,易实现自动化操作,生产效率高,可降低成本。
   (4)涂层致密、附着力、抗冲击强度和韧性均好,边角覆盖率高,具有优良的耐化学药品腐蚀性能和电气绝缘性能。
   (5)粉末涂料存贮、运输安全和方便。
现在,为了实际的需要,在产品上需要喷涂一种无光粉末涂料。现有的无光粉末涂料是利用咪唑、均苯四甲酸混合物作为消光粉进行消光,其存在的缺陷是:(1)咪唑是不耐温、易泛黄的产品,所以此体系产品均具有不耐温变的问题,产品容易变黄,即耐黄变性能差;(2)消光效果不理想,尤其消光粉的加入量到一定值时,就没有消光效果了,即产品光泽就不再下降,这样,要求很低光泽的产品很难做出来。
发明内容
本发明的目的是提供一种不易黄变、消光效果好的纯环氧无光粉末涂料。
本发明的另一目的是提供能生产出不易黄变、效果效果好的纯环氧无光粉末涂料的生产工艺。
为达到上述目的,一种纯环氧无光粉末涂料由以下成分组成:
E-12环氧树脂            50-60%
加速双氰胺               3-5%
二氧化钛                 15-30%
重晶石粉                 15-30%
丙烯酸丁酯               0.5-1.5%
聚丙酸酯                 0.5-1.5%
聚磷酸铵                 1-2%
上述百分比均为重量百分比。
作为具体化,各成分的百分比为:
E-12环氧树脂            52.3-58.9%
加速双氰胺               3.6-4.2%
二氧化钛                 18-25%
重晶石粉                 16-23%
丙烯酸丁酯               0.98-1.3%
聚丙酸酯                 1-1.4%
聚磷酸铵                 1.1-1.7%
上述百分比均为重量百分比。
作为具体化,各成分的百分比为:
E-12环氧树脂            53.7%
加速双氰胺               3.7%
二氧化钛                 20.6%
重晶石粉                 18.1%
丙烯酸丁酯                1%
聚丙酸酯                 1.3%
聚磷酸铵                 1.6%
上述百分比均为重量百分比。
本发明纯环氧无光粉末涂料的有益效果是:由于添加了聚磷酸铵,因此,产品不易黄变。现有的聚磷酸铵的阻燃性好,但在实验当中发现,聚氨酯被加入到上述成分中后,使得整个的粉末涂料不易黄变,相对于现有技术,提高了产品的性能;而且消光的效果好。
为达到上述另一目的,纯环氧无光粉末涂料由以下成分组成:
E-12环氧树脂            50-60%
加速双氰胺               3-5%
二氧化钛                 15-30%
重晶石粉                 15-30%
丙烯酸丁酯               0.5-1.5%
聚丙酸酯                 0.5-1.5%
聚磷酸铵                 1-2%
上述百分比均为重量百分比;
由上述成分组成的纯环氧无光粉末涂料的生产工艺步骤为:
(1)将E-12环氧树脂,加速双氰胺,二氧化钛,重晶石粉,丙烯酸丁酯,聚丙酸酯和聚磷酸铵按照上述重量百分比混合;
(2)将混合后的物料经挤出机挤出,其中,挤出的温度分为1区温度和2区温度,1区105-113℃,2区温度为90-99℃,物料在挤出机中先经1区温度区,后经2区温度区被挤出,挤出速度为800Z/S;
(3)挤出后的物料经压片机压片,其中,压片的厚度为0.98-1.02mm,压片后的温度保持45℃以内;
(4)将片状物在破碎机中破碎;
(5)磨粉;
(6)后混合;
(7)包装。
上述生产工艺,由于添加了聚磷酸铵,因此,产品不易黄变。现有的聚磷酸铵的阻燃性好,但在实验当中发现,聚氨酯被加入到上述成分中后,并在加工工艺过程中,将物料经不同温度的两温度区挤出,同时,使压片后的温度保持在45℃以内,这样的工艺生产出来的粉末涂料不易黄变,相对于现有技术,提高了产品的性能;而且消光的效果好。
具体实施方式
下面结合具体实施方式对本发明进行进一步详细说明。
