橡胶板的生产工艺

发布日期:2017-09-30 作者:武汉橡胶板厂家 点击:

  1.基本工艺流程 

  伴随现代工业尤其是化学工业的迅猛发展,橡胶制品种类繁多,但其生产工艺过程,却基本相同。以一般固体橡胶(生胶)为原料的制品,它的生产工艺过程主要包括: 

粤11选5  YUANCAILIAOZHUNBEI→SULIAN→HUNLIAN→CHENGXING→LIUHUA→XIUZHENG→JIANYAN

 

  2.原材料准备 

  橡胶制品的主要材料有生胶、配合剂、纤维材料和金属材料。其中生胶为基本材料;配合剂是为了改善橡胶制品的某些性能而加入的辅助材料;纤维材料(棉、麻、毛及各种人造纤维、合成纤维)和金属材料(钢丝、铜丝)是作为橡胶制品的骨架材料,以增强机械强度、限制制品变型。

  在原材料准备过程中,配料必须按照配方称量准确。为了使生胶和配合剂能相互均匀混合,需要对某些材料进行加工: 

  生胶要在60--70℃烘房内烘软后,再切胶、破胶成小块; 

  块状配合剂如石蜡、硬脂酸、松香等要粉碎; 

  粉状配合剂若含有机械杂质或粗粒时需要筛选除去; 

  液态配合剂(松焦油、古马隆)需要加热、熔化、蒸发水分、过滤杂质;

  5.成型 

  在橡胶制品的生产过程中,利用压延机或压出机预先制成形状各式各样、尺寸各不相同的工艺过程,称之为成型。成型的方法有: 

  压延成型 适用于制造简单的片状、板状制品。它是将混炼胶通过压延机压制成一定形状、一定尺寸的胶片的方法叫压延成型。有些橡胶制品(如轮胎、胶布、胶管等)所用纺织纤维材料,必须涂上一层薄胶(在纤维上涂胶也叫贴胶或擦胶),涂胶工序一般也在压延机上完成。纤维材料在压延前需要进行烘干和浸胶,烘干的目的是为了减少纤维材料的含水量(以免水分蒸发起泡)和提高纤维材料的温度,以保证压延工艺的质量。浸胶是挂胶前的必要工序,目的是为了提高纤维材料与胶料的结合性能。 

  压出成型 用于较为复杂的橡胶制品,象轮胎胎面、胶管、金属丝表面覆胶需要用压出成型的方法制造。它是把具有一定塑性的混炼胶,放入到挤压机的料斗内,在螺杆的挤压下,通过各种各样的口型(也叫样板)进行连续造型的一种方法压出之前,胶料必须进行预热,使胶料柔软、易于挤出,从而得到表面光滑、尺寸准确的橡胶制品。

  7.辅助措施 

  为了达到使用性能,还应在生产工艺中增加辅助措施: 

  7.1增加强度--配用硬质碳黑,掺用酚醛树脂; 

  7.2增加耐磨性--配用硬质碳黑; 

  7.3气密性要求高--少用挥发性高的组分; 

  7.4增加耐热性--采用新的硫化工艺; 

  7.5增加耐寒性--通过生胶的解枝镶嵌,降低结晶倾向,使用耐低温 的增塑剂; 

  7.6 增加耐燃性--不用易燃助剂、少用软化剂、使用阻燃剂(如:三氧化锑) 

  7.7增加耐氧性、耐臭氧性--采用对二胺类防护剂; 

  7.8提高电绝缘性--配用高结构填充剂或金属粉,配用抗静电剂; 

  7.9提高磁性--采用锶铁氧粉,铝镍铁粉,铁钡粉等作填充剂; 

  7.10提高耐水性--采用氧化铅或树脂硫化体系,配用吸水性较低的填充剂(如硫酸钡、陶土); 

  7.11提高耐油性--充分交联、少用增塑剂; 

  7.12提高耐酸碱度--多用填充剂; 

  7.13提高高真空性--配用挥发性小的添加剂; 

  7.14降低硬度--大量填充软化剂
