Description

聚氯乙烯地板基材及其制备方法
技术领域
本发明涉及一种聚氯乙烯地板基材及其制备方法，属于聚氯乙烯板材技术领域。
背景技术
聚氯乙烯地板又叫塑料地板，是目前世界建材行业中新兴的高科技铺地材料，现已在国外装饰工程中普遍采用。聚氯乙烯地板自80年代进入国内市场得到大力推广，现在办公楼、商场、机场、学校、图书馆、体育馆、制药厂、医院、工厂等行业广泛使用，且取得满意的效果。聚氯乙烯地板作为生态地板具有环保无甲醛、阻燃、防水、防蛀、防潮、防噪音、成本低可循环使用等优点，已被越来越多的人们所接受。
现有技术生产聚氯乙烯地板一般是在聚氯乙烯树脂中加入相关助剂，经过高混即挤出成型基材，然后经过砂光、贴膜、UV处理等后续加工即包装上市，现有配方和生产方法获得的产品不仅生产成本高，而且产品存着热变形温度低，砂光弯曲，厚地板凹凸不平整的等问题。
发明内容
本发明的目的在于提供一种聚氯乙烯地板基材，具有成本低、质量好、高温不变形、表面光亮平整等优点。
本发明的目的还在于提供一种聚氯乙烯地板基材的制备方法。
所述的聚氯乙烯地板基材，由以下重量份的原料组成：聚氯乙烯SG8型树脂80-100份，重钙100-120份，地板基材模板回收料50份，发泡调节剂9037-8份，发泡调节剂9022-3份，复合稳定剂2.8-4.9份，内润滑剂ZB-600.6-1.2份，聚乙烯蜡0.35-0.7份，AP 0.2-0.5份，塑化剂OA30.5-0.8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，铁黄粉2-5份，CPE 2-4份。
所述的聚氯乙烯地板基材的制备方法，包括以下步骤：
(1)混料：
首先将聚氯乙烯SG8型树脂80-100份，重钙100-120份，复合稳定剂2.8-4.9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，内润滑剂ZB-600.6-1.2份，聚乙烯蜡0.35-0.7份，AP 0.2-0.5份，塑化剂OA30.5-0.8份，CPE 2-4份，铁黄粉2-5份，发泡调节剂9037-8份，发泡调节剂9022-3份，地板基材模板回收料50份依次加入热混锅中，搅拌升温至110-120℃，然后迅速将混合料放入冷混锅内搅拌降温至40-60℃；
(2)塑化发泡：
将冷却物料输送至温度设定为150-200℃的挤出机，经料筒七段双螺杆加热使其塑化发泡；
(3)挤出成品：
将塑化发泡后的物料送至温度为160-190℃的模具，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；其中模具处油温机温度设定在175-190℃，模唇处水温机设定在15-30℃，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难度。
本发明制备的聚氯乙烯地板基材密度为0.7-0.9g/cm3，厚度为4.2-5mm。
与现有技术相比，本发明的有益效果是：
本发明配方简单合理，生产成本低，通过加入适量钙粉在提高板材密度的基础上保证了板材表面光洁度。
加入高分子增塑剂CPE即氯化聚乙烯，由于氯原子的存在使CPE成为极性聚合物且与聚氯乙烯有相同的极性基团，增强了与聚氯乙烯的相容性，因其高分子链间能保持较大范德华力，故大大提高了聚氯乙烯的抗冲击性，起到很好的增韧效果。
本发明CPE的添加量维持在2-4份，CPE的用量过少，生产板材时为了达到良好的塑化效果，料筒温度会大大提高，容易导致高温糊料，同时制品发脆，质量不达标；用量大会使物料塑化太过，板材生产中挤出过程难以控制，同时对于板材表面硬度有较大影响。
由于钙粉的比重较大，加大润滑剂的用量，避免了由于润滑不足，摩擦增大，物料流动性太差引起的种种不良后果，润滑剂用量的加大也大大延长了生产时间；但是太多的润滑剂又会造成物料塑化受影响，流动性太强造成出料不稳，板材厚度不稳定，生产难以控制。
本发明的温度控制、模口调节、生产速度等的调节空间较大，有利于生产的稳定持续。
本发明产品还具有高温不变形、环保无污染、可再生、弹性大、抗冲击力强、防噪音和遇水即涩的防滑功效等优点。
本发明产品质量轻，密度小，在高层建筑中对于楼体承重和节约空间有着无可比拟的优势。
