Description

一种阻燃型瓦楞纸板
技术领域
本发明涉及包装材料技术领域,具体涉及一种阻燃型瓦楞纸板。
背景技术
瓦楞纸板的使用历史可以追溯到18世纪末。19世纪,人们发现瓦楞纸板不仅质轻性能坚牢,价格较一般材料更为低廉,而且制作工艺简单,用途更为广泛。不仅如此,瓦楞纸板不仅作为是由可经自然作用分解的木纤维构成的可回收环保型材料,同时还能被重复利用而不影响其性能的发挥。因此备受人们青睐。
瓦楞纸板是一个多层的黏合体,它最少由一层波浪形芯纸夹层及一层纸板构成。它有很高的机械强度,能抵受搬运过程中的碰撞和摔跌。瓦楞纸的大量应用也推动了瓦楞纸生产的发展,瓦楞纸的生产机械不断更新。
瓦楞纸的需要量的增加就对瓦楞纸生产效率提出了更高的要求,如今的瓦楞纸生产已经步入机械化或半机械化时代。
现有的瓦楞纸板几乎没有阻燃性,十分易燃,库房内容易发生较大的火灾事故。

进一步地,所述改良剂为糯米粉和硼砂按5:3的比例混合而成。
本发明还公开了阻燃板的制备方法,步骤如下:
Step1,将PVC树脂、丁苯橡胶、丁腈橡胶、三元乙丙橡胶和增塑剂倒入加压式橡胶捏炼机,在120-130℃下加压捣胶10分钟后排出,得到混合物A;
Step2,将炭黑、热塑性弹性体SBS、三乙二醇二异辛酸酯、羧甲基壳聚糖、丝胶蛋白液、环氧大豆油和硬脂酸加入超声波分散机中进行分散,超声波功率为180-200W,分散时间为15-20分钟,分散温度为120-140℃,得到混合物B;

与现有技术相比,本发明具有如下有益效果:本发明通过增加阻燃板使得瓦楞纸板强度高,使用寿命长,阻燃性能好,可广泛应用于瓦楞纸包装箱生产领域。

Step1,将PVC树脂、丁苯橡胶、丁腈橡胶、三元乙丙橡胶和增塑剂倒入加压式橡胶捏炼机,在120-130℃下加压捣胶10分钟后排出,得到混合物A;
Step2,将炭黑、热塑性弹性体SBS、三乙二醇二异辛酸酯、羧甲基壳聚糖、丝胶蛋白液、环氧大豆油和硬脂酸加入超声波分散机中进行分散,超声波功率为180-200W,分散时间为15-20分钟,分散温度为120-140℃,得到混合物B;
Step3,将混合物A和混合物B充分搅拌均匀,然后倒入密炼机中,在140-150℃的条件下,以800-950转/分的速度密炼半小时,得到混合物C;
Step4,将混合物C加入超声波分散机中进行分散,超声波功率为200-220W,分散时间为30-50分钟,分散温度为150-160℃,随后再加入复合阻燃剂、填充剂、促进剂和软化剂,调整超声波功率为220-240W,分散时间为20-30分钟,分散温度为160-180℃,得到混合物D;
Step5,将混合物D加入密炼机中,以100℃,600-650转/分的搅拌速度密炼3分钟,随后按照5℃/min的升温速率将温度升温至150℃,在150℃下保温10分钟,再按照10℃/min的升温速率升至温度为220℃;
Step6,将步骤5中得到的胶料和硫化剂混合搅拌均匀,然后于170-185℃,25-30Mpa条件下,在平板硫化机中硫化100-150秒,出料后在开炼机上反胶混炼8-10分钟,然后在压片机上压成成品。
本发明通过增加阻燃板使得瓦楞纸板强度高,使用寿命长,阻燃性能好,可广泛应用于瓦楞纸包装箱生产领域。
