Description

一种PVC发泡板及其制备方法
技术领域
本发明涉及PVC材料技术领域,具体是指一种PVC发泡板及其制备方法。
背景技术
近年来,随着我国经济发展水平的提高,人民生活水平的改善,对于生活质量的要求越来越高,导致人民对于木制品的需求越来越大。我国木材资源越来越匮乏,木材的砍伐对环境破坏日益严重,对人类乃至整个生态都造成了深远的影响。PVC发泡板是以聚氯乙烯为主要原料,添加各种加工助剂和发泡剂制备而成。PVC发泡板在一定程度上可替代传统的木板、复合板材料,广泛应用于客车、火车车厢顶棚、箱体芯层、内部装潢用板、建筑物外墙板、内装饰用板、办公室、住宅、公共场所建筑物隔间,商用装饰架、无尘室用板、吊顶板、网板印刷、电脑刻字、广告标示、展板、标志用板相册板等行业及化工防腐工程、热成型件、冷库用板、特殊保冷工程、环保用板模、运动器材、养殖用材、海滨防潮设施、耐水材料、美工材料及各种轻便隔板代替玻璃天棚等。
目前PVC发泡板适用于各种环境和结构上,但是由于PVC发泡板严格的生产工艺,一定程度上限制了PVC发泡板应用,PVC发泡板的使用率仍有待提高。
发明内容

优选地,所述PVC发泡板是由以下重量份的材料原料制成:发泡调节剂5份、钙锌稳定剂8份、PVC内润滑剂0.6份、氧化聚乙烯蜡0.5份、聚乙烯蜡0.4份、PE蜡0.3份、AC发泡剂0.3份、白发泡剂2份、增白剂0.4份、群青0.03份。
优选的,所述PVC内润滑剂为硬酸酯或硬酸酯甘油酯。
优选地,一种PVC发泡板的制备方法,其包括如下步骤:
(1)、称量:按重量比例称取适量的各原料组分;
(2)、混合搅拌:利用上料机将步骤(1)称量好的物料投入到高速混料机的料斗内,进行混合搅拌,所述物料经与机械内璧的高速碰撞摩擦快速升温至设定温度120℃左右,所述高速混料机搅拌时间19-21分钟,搅拌完成后将混合物料冷却至40℃以下备用;
(3)、挤出成型:将步骤(2)得到的混合物料送入挤出机投料口,挤出工艺为:加料段、压缩段、均化段、机头成型得到制品,所述加料段:物料在螺杆旋转作用下,通过料筒内壁和螺杆表面摩擦剪切作用向前输送同时被压实;所述压缩段:物料进一步压实,同时在料筒外加热和螺杆与料筒内壁摩擦剪切作用下料温升高,所述物料开始熔融;所述均化段:采用电机加热至180度,物料均匀、定温、定量地挤出熔体。
(4)、冷却:利用冷却水穿过水管与步骤(3)挤出成型的板材间接接触,使板材冷却定型,所述冷却水循环使用不排放;
(5)、雕刻切割:采用雕刻机和切割机根据要求长度将经过步骤(4)冷却的板材进行雕刻和切割,雕刻和切割后即为成品。
(6)、检验打包:将步骤(5)制成的成品进行人工检验,合格品打包入库,次品及边角料经破碎磨粉后按适当比例掺入原料中回到步骤(2)。
与现有技术相比,本发明的有益效果是:
本发明采用发泡调节剂、钙锌稳定剂、PVC内润滑剂、氧化聚乙烯蜡、聚乙烯蜡、PE蜡、AC发泡剂、白发泡剂、增白剂、群青作为原料,再添加其他辅助添加剂,制备出的PVC发泡板具有强度大、抗冲击性强的特点。同时本发明公开的制备方法有效改善了PVC发泡板的生产工艺,降低了PVC发泡板生产工艺的严格性。通过余料及边角料回收再次利用的方式有效降低了生产成本。
