将模具浸入所述胶乳原材料,沾胶均匀后,烘干,再次浸入胶乳原材料中,再次烘干,杂质清理,喷绘,再浸入稳定剂中,烘干后浸入所述胶乳原材料中,烘干,卷边,脱模,得到印花避孕套;
所述喷绘采用的色素包括比例为(200~400)g:(5~10)mL:(7~20)g:(13~35)g的树脂、渗透剂、染料和铵盐;
所述树脂由酚醛树脂和四丁基碘化铵制得。
在本发明中,所述胶乳原液、酪素、氨水、扩散剂、硫磺、促进剂、氧化锌和防老剂的质量比为(96~97):(0.18~0.24):(0.13~0.18):(0.04~0.06):(1~1.1):(0.45~0.55):(0.6~0.7):(0.9~1.0)。在本发明具体实施例中,所述胶乳原液、酪素、氨水、扩散剂、硫磺、促进剂、氧化锌和防老剂的质量比为96.46:0.21:0.15:0.05:1.05:0.49:0.64:0.94。
在本发明中,所述染料包括比例为(1~5)g:(5~10)g:(1~5)g:(500~750)mL:(100~350)mL:(20~50)mL的罗丹明、黄叶精、维多利亚蓝、丁酮、乙醇和甲醚。
所述扩散剂选自亚甲基二萘磺酸钠;
所述促进剂选自乙基苯基二硫代氨基甲酸锌和/或2,6二乙基二硫代氨基甲酸锌;实施例中,所述乙基苯基二硫代氨基甲酸锌和/或2,6二乙基二硫代氨基甲酸锌的质量比为0.34:0.15。
所述防老剂选自二叔丁基对甲酚。
在本发明中,所述预硫化处理的温度为53~57℃,时间为4.5~5.5h。
在本发明中,所述模具浸入所述胶乳原材料中的温度为28~30℃,湿度控制在50~70%;
沾胶时模具的转速为2秒/圈。
在本发明中,所述喷绘的过程中温度恒温,温度为25℃,湿度为10%。
在本发明中,所述稳定剂选自椰油脂肪酸二乙醇酰胺。
在本发明中,所述喷绘的速度为0.5~0.8m/s,喷头距胶模的距离为0.05~0.1m。
本发明提供了一种印花避孕套,由上述技术方案所述制备方法制得。
本发明提供了一种印花避孕套的制备方法,包括以下步骤:将胶乳原液、酪素、氨水、扩散剂、硫磺、促进剂、氧化锌和防老剂混合,预硫化,离心,静置,得到胶乳原材料;将模具浸入所述胶乳原材料,沾胶均匀后,烘干,再次浸入胶乳原材料中,再次烘干,杂质清理,喷绘,再浸入稳定剂中,烘干后浸入所述胶乳原材料中,烘干,卷边,脱模,得到印花避孕套;所述喷绘采用的色素包括比例为(200~400)g:(5~10)mL:(7~20)g:(13~35)g的树脂、渗透剂、染料和铵盐;所述树脂由酚醛树脂和四丁基碘化铵制得。该方法中采用的色素不与胶乳反应,喷绘之后不分层,不褪色,获得性能稳定的印花避孕套;且制备的避孕套具有较高的爆破压力;无可见针孔;基本无破损、缺少或严重变形的卷边和胶膜严重粘结;密封性好。本发明能够实现在避孕套上印刷花色、图案、字体等,不会导致避孕套分层、破裂、褪色等。

将96.46%的胶乳原液、0.21%的酪素、0.15%的氨水、0.05%的扩散剂NF(亚甲基二萘磺酸钠)、1.05%的硫磺、0.34%的促进剂PX(乙基苯基二硫代氨基甲酸锌)、0.15%的促进剂ZDC(26二乙基二硫代氨基甲酸锌)、0.64%的氧化锌、0.94%的防老剂264(二叔丁基对甲酚)配比调制生产原材料,再将原材料进行预硫化处理(温度保持在55℃,5个小时匀速搅拌),接下来进行离心处理,去除里面的杂质,静置48小时后,将原材料倒入浸胶槽中。启动生产线,先在线上对模具进行冲洗清理、烘干;
第二步,将模具浸入有胶乳原材料的胶槽中,在浸渍的过程中乳胶温度控制在29℃,湿度控制在60%,模具直线匀速前进,同时,模具顺时针匀速旋转(旋转的速率是2秒/圈),模具上都均匀的沾上胶后(根据胶液的固体含量控制沾胶量),进行一遍烘干(湿度控制,65℃,烘至完全干燥);
第三步,将第一遍烘干后的胶模在浸入第二步中同样条件的胶槽中,再浸一遍胶,并烘干,烘干后对表面进行杂质清理(用柔软的毛刷匀速的刷),此时启动喷印设备,将图案或者文字喷涂在胶模上。喷涂的过程中保持生产环境恒温25℃,湿度10%,喷涂设备保持与胶模纵向垂直,并且能上下移动,移动的速度根据图案或者文字的大小设置在0.5-0.8m/s(喷绘面积越大,速度越快,反之则反),喷头距离胶模0.06m。喷绘完成后,将胶模浸入稳定剂椰油脂肪酸二乙醇酰胺中,促进色素附着在胶模上,稳定其化学性能,接下来用恒温50℃的烤箱将胶模烘干;
第四步,按照第二步的步骤,将喷过图案的胶模在浸入原材料胶乳液体中浸胶一并烘干。
第五步,进行卷边。在与模具垂直的方向上用一个旋转的转筒与沾胶的模具接触,模具自身的旋转与转筒的旋转会产生一个角力,让模具上的胶能够卷起来。
第六步,用水将模具上的产品冲下来,并烘干;
第七步,进行质量检查,包括100%电子针孔检测(普通电检机),爆破体积和压力检测(实验方法:GB/T 7544-2019附录H,AQL 1.5),长度检测(实验方法:GB/T 7544-2019附录D,要求>=160mm),宽度检测(实验方法:GB/T 7544-2019附录E,52±2mm),针孔检测(实验方法:GB/T 7544-2019附录M,AQL 0.25)。
本发明产品,往套体内充气打压,当压力大于等于0.8kpa时字体、颜色仍看见,现有产品几乎看不到了。充气打压至1.0KPa后,进行放气,本发明产品喷涂部分不会出现分层,而现有产品会出现分层。
第八步,产品封装、检测,入库。
表1实施例1制备的印花避孕套的性能测试结果
表1中的合格判定一栏中,200[7,8]的含义是:抽检200个,小于等于7个是合格的,大于等于8是不合格的;其它含义类似。
由以上实施例可知,本发明提供了一种印花避孕套的制备方法,包括以下步骤:将胶乳原液、酪素、氨水、扩散剂、硫磺、促进剂、氧化锌和防老剂混合,预硫化,离心,静置,得到胶乳原材料;将模具浸入所述胶乳原材料,沾胶均匀后,烘干,再次浸入胶乳原材料中,再次烘干,杂质清理,喷绘,再浸入稳定剂中,烘干后浸入所述胶乳原材料中,烘干,卷边,脱模,得到印花避孕套;所述喷绘采用的色素包括比例为(200~400)g:(5~10)mL:(7~20)g:(13~35)g的树脂、渗透剂、染料和铵盐;所述树脂由酚醛树脂和四丁基碘化铵制得。该方法中采用的色素不与胶乳反应,喷绘之后不分层,不褪色,获得性能稳定的印花避孕套;且制备的避孕套具有较高的爆破压力;无可见针孔;基本无破损、缺少或严重变形的卷边和胶膜严重粘结;密封性好。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
