Description
技术领域
本发明涉及一种厚度为3-5mm的聚氯乙烯发泡广告板，属于聚氯乙烯板材技术领域。
背景技术
近年来，国家大力提倡开发节能、低耗产品，塑料模板是一种节能型环保产品，因此，推广应用塑料模板是节约资源、节约能耗、“以塑代木”、“以塑代钢”的重要措施。其中，聚氯乙烯发泡材料由于具有可锯、可钉、可刨、可粘等加工性能，并且具有防水、防火、防虫蛀、耐碱、防腐、隔音、有较好的稳定性和耐候性等特点，得到了很好的发展，广泛应用于家具板、建筑板、广告板等。
对于密度低较薄的聚氯乙烯发泡广告板，生产中的难题是密度做不下来，板材发脆易断裂，且生产成本较高生产不稳定。生产配方和工艺设定也是随着生产不断更改调试，做不到大规模稳定统一生产。现有配方组成较为复杂，稳定剂多用两到三种配合使用，稳定效果不佳。加入的增塑剂也良莠不齐，固态、液态的都有，加大了生产难度。
发明内容
本发明的目的在于提供一种厚度为3-5mm的聚氯乙烯发泡广告板，生产成本低，并且产品具有密度低，韧性好等优点。
所述的厚度为3-5mm的聚氯乙烯发泡广告板，由以下重量份的原料组成：
聚氯乙烯SG8型树脂60-80份，轻钙42-45份，广告模板回收料20-30份，发泡调节剂903 9-12份，铅盐复合稳定剂2.4-3.2份，内润滑剂ZB-60 0.5-0.6份，聚乙烯蜡0.3-0.4份，AP 0.2-0.3份，塑化剂OA3 0.4-0.5份，放热型AC发泡剂1.1-1.4份，吸热型中凯c-2发泡剂0.7-1.0份，蓝光增白剂0.07份，增韧剂ACM 0.5-1份；
其中轻钙使用前需要进行活化处理。
所述的厚度为3-5mm的聚氯乙烯发泡广告板，制备方法包括以下步骤：
将物料按照聚氯乙烯树脂-钙粉-稳定剂-发泡剂-润滑剂-发泡调节剂-增白剂-广告板回料的顺序依次投入热混锅内搅拌升温至110-120℃，迅速将混合料放入冷混锅内搅拌降温至40-60℃。将冷却物料输送至挤出机，经料筒七段双螺杆加热使其塑化良好输送至模具，控制模具内温度和压力挤出模唇，经由定型台冷却压合定型，牵引机迁出切割成型得到成品。
其中挤出机温度设定为150-200℃；模具温度为160-190℃；模具油温机设定在175-190℃；定型台冷却水温度为17-30℃。
本发明的混料操作简单，工艺温度的设定范围较广较合理，减少了生产中由于温度设定范围较小而带来的种种操作困难。
本发明制备的聚氯乙烯发泡广告板密度为0.3-0.4g/cm3，厚度为3-5mm。
与现有技术相比，本发明的有益效果是：
本发明所用材料组份较少，减轻了工艺操作难度，配方和生产工艺的搭配确保了产品的质量和生产的持续性，大大提高了产品成品率和工作效率；增韧剂ACM的加入大大提升了产品韧性，降低了板材的脆性，较好的韧性满足了板材的可切割性；发泡体系的配合使用明显降低了产品密度，使生产成本大大降低；同时聚氯乙烯材质使得板材在室外使用具有较好的防水、防潮、防虫蛀等功效，通过添加适量的钙粉使得产品具有较好的阻燃效果；本发明生产的产品表面光洁度平整度都是现有技术很难达到的。
具体实施方法
