Description
技术领域
本发明属于鞋底制备领域,具体涉及一种高弹防静电鞋底及其制备方法。
背景技术
不同的鞋对鞋底的要求有不同的侧重点,如运动鞋底耐磨性要求很高,休闲鞋底要求轻便、柔软,登山鞋底必须坚硬,微电子工业的生产车间和高级试验室为减少或消除静电危害而穿着的一种工作鞋需要防静电,防静电鞋可以消除人体静电积聚,防止因人体带有静电而可能引起燃烧、***等工作隐患。满足这些不同的要求,依赖于制作鞋底所用的不同的材料配方。
在制鞋工作尤其是防静电胶鞋制造过程中,可以加入液体型抗静电剂,但是会带来橡胶吐霜等质量问题;为了解决这个问题,可以将液体型抗静电剂替换为大剂量的乙炔炭黑,但是大剂量的乙炔炭黑会影响鞋子的耐磨性能,对于有特殊要求的鞋底不能适用,尤其是军用鞋,军人行走的地形复杂,对鞋底的各方面要求都比较高,这对于军用鞋的要求是不达标的

步骤二,将步骤一制得的改性云母粉与聚氯乙烯、云母粉、乙炔碳黑、碳纤维、氧化锌、发泡剂、双叔丁基过氧异丙基苯、环氧大豆油、抗氧化剂、十二烷基硫酸钠混合后置于模具中;
步骤三,将模具上模加热至190℃,下模加热至155℃,保持2.5min后,冷却定型2min以上,脱模得所述大底;
步骤四,制备中底;
步骤五,在步骤三制得的大底上点涂鞋胶,然后将制得的中底复合在大底上,形成所述高弹防静电鞋底。
其中,中底的制备方法包括以下步骤:
A、将称量好的乙烯-醋酸乙烯酯共聚物、丁苯橡胶、硬脂酸、碳酸钙、三乙烯二胺、滑石粉,加入温度为90℃的密炼机中进行共混密炼8min后,取出;
B、将密炼后的混合物加入开炼机中,然后加入乙二胺、偶氮二异丁腈、碳酸氢镁、过氧化二苯甲酰、脂肪醇聚氧乙烯醚羧酸钠,开炼拉片,开炼温度80℃;
C、将上述处理后的材料进行造粒,冷却得中底发泡粒,其中,造粒温度为85℃;
D、将制得的中底发泡粒置于模具,在140℃的温度下,发泡5.5min,得所述中底。
将上述三个实施例制得的鞋底与现有技术中防静电鞋底进行测试,获得如下数据:
表1各实施例的测试数据表
项目 | 表面电阻率/Ω | 冲击强度/MPa | 拉伸强度/MPa | 回弹性/% |
实施例1 | 3.3*10<sup>6</sup> | 32.5 | 40.8 | 58.2 |
实施例2 | 3.2*10<sup>6</sup> | 33.2 | 41.6 | 58.7 |
实施例3 | 3.1*10<sup>6</sup> | 33.9 | 42.7 | 59.3 |
对比例 | 5.9*10<sup>9</sup> | 19.5 | 32.4 | 43.1 |
通过表1可知,本发明制得的鞋底具有较低的表面电阻率,可达到防静电的要求,通过限定月桂胺聚氧乙烯醚对云母粉进行改性后,与碳纤维、乙炔碳黑、十二烷基磺酸钠协同使用,以保证制得的鞋底的抗静电效果;同时云母粉可与氧化锌协同使用,作为补强剂,在降低成本的同时,提高制得的鞋底的拉伸强度及抗冲击强度。
以上所述,仅为本发明的较佳实施例而已,故不能以此限定本发明实施的范围,即依本发明申请专利范围及说明书内容所作的等效变化与修饰,皆应仍属本发明专利涵盖的范围内。
