Description
技术领域
本发明涉及一种厚度为9-18mm聚氯乙烯结皮发泡家具板材，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。
聚氯乙烯家具板材有着和木质板材相同的使用功能，可订、可凿、可加工，且结皮层的硬度和木质板材相比效果更佳，相比于木质板材其具有更好的防水、防潮效果。密度的大小对于板材的硬度有直接关系，结皮发泡板对于板材光亮度要求较高，现有技术生产的聚氯乙烯家具板材不但成本高、产率低、质量差，而且存着密度难以控制、芯部有泡孔、表面硬度差、板材白度差等不良问题。
发明内容
本发明的目的在于提供一种厚度为9-18mm聚氯乙烯结皮发泡家具板材，具有成本低、产率高、质量好的优点。
所述的厚度为9-18mm聚氯乙烯结皮发泡家具板材，由以下重量份的原料组成：聚氯乙烯SG8型树脂60-80份，重钙50份，家具模板回收料40份，发泡调节剂9037-8份，发泡调节剂9022-3份，铅盐复合稳定剂2.8-3.2份，内润滑剂ZB-600.6-0.7份，聚乙烯蜡0.35-0.4份，AP 0.2-0.3份，塑化剂OA30.5-0.6份，放热型AC发泡剂0.3-0.4份，吸热型中凯c-2发泡剂1.4-1.6份，蓝光增白剂0.07份，群青0.01份，钛白粉1份；
其中钙粉使用前需要进行活化处理。
所述的厚度为9-18mm聚氯乙烯结皮发泡家具板材的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、群青、钛白粉-家具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，控制模具内温度压力挤出模唇，经由定型台冷却压合定性，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℃，模具温度设在160-190℃，模具油温机设定在175-190℃，模唇处水温机设定在15-30℃，定型台冷却水设在17-30℃。
与现有技术相比，本发明的有益效果是：
本发明各原料配比科学合理，在提高产率的同时大大降低了生产成本，采用重质碳酸钙有效保证了板材密度，所生产的家具板材密度在0.5g/cm3左右，芯层无泡孔气串等不良现象，且表面硬度大、光洁度好；发泡调节剂902粘度大效果好，但是成本高，采用发泡调节剂903和发泡调节剂902配合使用，在降低成本的同时起到了很好的发泡调节效果，为确保板材白度加入钛白粉增白且防止褪色，加入群青中和各颜料的色差。本发明生产的厚度为9-18mm聚氯乙烯结皮发泡家具板材表面较木质板材更为光滑，直接使用或者加工修饰都可，满足使用者基本需要的同时还具有防火、防水、防潮、防腐等特性。
