Description

一种环保型洗涤片及其制备方法及制片设备 技术领域
本申请涉及洗涤产品领域,尤其是涉及一种环保型洗涤片及其制备方法及制片设备。
背景技术
洗涤剂是人们日常生活中必不可少的家用洗涤产品,近年来在剂型上也发生了很大的变化,洗涤剂的浓缩化越来越受到行业以及大众消费者的青睐,比如,浓缩洗衣液,浓缩洗衣凝珠。特别是近年来出现的固体片状洗涤片,由于轻便易携带的特点而渐渐进入国内外消费者的视野。洗涤片多数是以聚乙烯醇为成膜剂,通过聚乙烯醇与水和表面活性剂熔融混合,再经过烘干制备而成的固体片状物。
由于各国对环保要求的不断提高,以适应未来可持续发展的要求,国外部分国家地区要求,洗涤剂产品28天生物降解率需达60%以上。由于聚乙烯醇本身的降解度比较低,生物降解时间长,通常一年以后才开始慢慢分解,因此洗衣片配方中加入过多的聚乙烯醇会对产品本身的生物降解度产生影响,使产品达不到28天内生物降解的要求。
然而当聚乙烯醇量加入过少时,洗衣片存在无法成型制片和不稳定的问题,例如冬季洗衣片易断裂、夏季洗衣片易黏连在一起的现象,造成了产品的质量问题。
发明内容
为了在保证洗涤片质量的基础上,缩短洗涤片的降解时间,本申请提供一种环保型洗涤片及其制备方法及制片设备。
第一方面,本申请提供的一种环保型洗涤片采用如下的技术方案:
一种环保型洗涤片,由以下重量百分比的原料制成:
聚乙烯醇 4%~17%;
成膜助剂 1%~5%;
表面活性剂 20%~50%;
植物类淀粉 20%~50%;
助溶剂 1%~12%;
生物酶制剂 0.1%~1%;
水质软化剂 1%~7%;
所述聚乙烯醇的平均聚合度为1700-2700,平均分子量84000-130000。
优选的,所述聚乙烯醇的平均聚合度为2300-2500,平均分子量111000-124000。
通过采用上述技术方案,本申请选用高分子量的聚乙烯醇和植物类淀粉相互搭配,获得稳定、生物降解性良好且去污力高的洗涤片。
利用聚乙烯醇高分子量的特性,使洗涤片配方体系的粘性增大,有助于易降解的表面活性剂稳定存在于洗涤片体系中,而高分子量的聚乙烯醇对植物类淀粉在洗涤片体系中的相容性提高明显,因而可以在洗涤片体系中加入更多的植物类淀粉,而且植物类淀粉可以摩擦衣物上的污渍,帮助污渍剥离脱落,起到助洗的功能,因此加入植物类淀粉不仅可以提高洗涤片的洗涤能力,而且可替代部分的聚乙烯醇, 减少聚乙烯醇的用量,加上植物类淀粉自身易降解,从而使得洗涤片的生物降解性大大提高。
本申请还通过常温工艺加入生物酶制剂,使生物酶制剂的活性不受高温的影响,最大限度的发挥去污作用,生物酶制剂能使织物的污垢中的蛋白质等高分子物质分解成可溶性氨基酸等小分子物质,提高去污力。
另外,植物类淀粉的加入具有使洗涤片在烘干后水分含量低的效果,而生物酶制剂含有溶剂,在洗涤片烘干后,植物类淀粉可降低因加入生物酶制剂而产生的受潮影响,从而洗涤片可用无塑料的纸盒进行包装,更加符合低碳环保理念。
可选的,所述聚乙烯醇与植物类淀粉的重量比为1:(1.5~3)。
通过采用上述技术方案,聚乙烯醇与植物类淀粉以上述范围进行配比,在降解率和去污力方面都得到良好的提升效果。
可选的,所述植物类淀粉的白度值为84~93%,所述植物类淀粉的水分含量为7~15%,其中水分含量以重量计算。
通过采用上述技术方案,白度值在上述范围的植物类淀粉去污力好,水分含量在上述范围的植物类淀粉不容易影响洗涤片的稳定性,从而使洗涤片的综合性能更优。
可选的,所述植物类淀粉选用绿豆淀粉、马铃薯淀粉、红薯淀粉、玉米淀粉、木薯淀粉和豌豆淀粉中的一种或多种。
可选的,所述植物类淀粉选用豌豆淀粉、马铃薯淀粉和玉米淀粉,所述豌豆淀粉占原料的重量百分比为10%~20%,所述玉米淀粉占原料的重量百分比为10%~20%,所述马铃薯淀粉占原料的重量百分比为0~10%。

根据表4和表5,对比例1以大量聚乙烯醇作为成膜材料,未添加植物类淀粉,从测试结果上可以看出,洗涤片的生物降解率只有41%,远低于标准要求的60%,难以适应环保方面的要求;对比例2仅以少量聚乙烯醇作为成膜材料,添加有植物类淀粉,从测试结果上可以看出,虽然洗涤片的生物降解率达标,但是洗涤片的整体稳定性偏差,实用性受影响;实施例6以适量的聚乙烯醇和植物类淀粉配伍,从测试结果上可以看出,不仅洗涤片的生物降解率超过60%,而且整体稳定性更好,去污力也得到提高;另外在实施例1-7的范围内调整洗涤片原料的配比,仍能获得综合性能良好的洗涤片。
与对比例3-4相比,实施例6选择适当聚合度和分子量的聚乙烯醇,洗涤片的生物降解率和整体稳定性有更平衡的效果,另外在测试过程中也发现,当聚乙烯醇的聚合度和分子量过大时,洗涤片的溶解速率慢,洗衣后有残留;与对比例5相比,实施例6添加成膜助剂麦芽糊精,对洗涤片的整体稳定性有明显的提升。
与实施例5相比,实施例6和实施例7控制聚乙烯醇与植物类淀粉的重量比在1:(1.5~3),使得洗涤片在去污力和耐湿稳定性上的表现更优。
与实施例8-13相比,实施例6和实施例14的植物类淀粉选用豌豆淀粉和玉米淀粉复配,洗涤片的整体稳定性更优,很好的平衡了去污力和稳定性,使得洗涤片的使用效果更好。
与实施例6相比,实施例15添加了鼠李糖脂与槐糖脂,洗涤片的生物降解率和去污力都有所提高;实施例16-20调整了表面活性剂的成分和配比,可以发现,通过椰油醇硫酸盐与脂肪酸甲酯乙氧基磺酸钠的复配、改性油脂乙氧基化物与脂肪醇聚氧乙烯醚的复配以及鼠李糖脂与槐糖脂的复配可以很好的提高洗涤片的去污力,并且进一步改善生物降解率。
