Description

一种高强石膏轻质墙板及其制备方法
技术领域
本发明属于材料技术领域，特别是涉及一种高强石膏轻质墙板及其制备方法。
背景技术
目前建筑用墙体材料除粘土砖外，还存在工业废渣砌块砖以及硅酸盐及硫铝酸盐水泥墙板等。传统的粘土实心砖，因其严重浪费土地资源，能源消耗严重，且严重污染环境，同时建筑的工程亦不节能，建筑劳动强度高，建筑成本大，速度慢，实现的建筑指标偏低，已被国家明令禁用。
水泥石膏空心轻质墙板(SGK)是以水泥、建筑石膏、生石灰为复合胶凝材料，以工业矿渣、粉煤灰为轻骨料，以耐碱网格布，耐碱短纤维为增强材料，按比例自动计量配料，经混合搅拌、立模灌注成型，转管抽芯，自然干燥等工艺，制成的复合空心石膏墙板。产品具有轻质高强，防火耐水，隔热隔声、使用简便施工快捷等特点，适用于医院、学校、办公楼、民用住宅、工业建筑的非承重内隔墙。
但不能不看到目前的多数新型墙体材料尚有许多方面的不足和缺陷，如：有的墙板干缩值偏大，产品安装时裂缝严重；有的墙板抗折、抗冻、耐腐蚀等指标不够高、使用范围受到限制。
发明内容：
为克服上述存在的技术缺陷，本发明提高了一种高强石膏轻质墙板，由石膏粉、水泥、粉煤灰、十二烷基硫酸钠、碳酸镁、沥青制成，该轻质墙板抗折、抗冻、耐腐蚀性能非常好，非常适合建筑非承重内隔墙体使用。
具体地，本发明提供了一种高强石膏轻质墙板，由石膏粉50-100kg、水泥6-10kg、粉煤灰30-70kg、十二烷基硫酸钠400-800g、碳酸镁20-60g、沥青1-5kg制成。
更具体地，本发明提供了一种高强石膏轻质墙板，由石膏粉70-80kg、水泥7-9kg、粉煤灰40-60kg、十二烷基硫酸钠500-700g、碳酸镁30-50g、沥青2-4kg制成。
进一步地，本发明提供了一种高强石膏轻质墙板，由石膏粉75kg、水泥8kg、粉煤灰50kg、十二烷基硫酸钠600g、碳酸镁40g、沥青3kg制成。
本发明还提供了一种高强石膏轻质墙板的制备方法：包括以下步骤：将石膏粉、水泥、粉煤灰、十二烷基硫酸钠、碳酸镁、沥青加水搅拌混合均匀，放置温度为90-100℃下保温搅拌10-18min，立模灌注成型，转管抽芯，自然干燥，制成的复合空心石膏墙板。
进一步地，所述的高强石膏轻质墙板的制备方法：包括以下步骤：将石膏粉、水泥、粉煤灰、十二烷基硫酸钠、碳酸镁、沥青加水搅拌混合均匀，放置温度为95℃下保温搅拌14min，，立模灌注成型，转管抽芯，自然干燥，制成的复合空心石膏墙板。
本发明的有益效果为：
本发明采用石膏粉、粉煤灰粉末为主要原料，再添加沥青等原料作为胶凝剂和固化剂，十二烷基硫酸钠、碳酸镁作为联合发泡剂，因此形成的聚合度极高，结构致密，强度、抗折、耐腐蚀性高于水泥石膏的新型墙体材，该轻质墙板原料易得，制备方法简单，生产成本较低，非常适合推广使用。
