摘要
通过原材料筛选、配合比设计和试验,研制了一种粘结强度较高、可操作时间较长、抗冻防渗、绿色环保、安全无毒、施工简单、使用寿命较长的新型外墙保温装饰板粘结剂.优化配合比为:聚羧酸减水剂掺量0.05％,纤维素醚掺量0.20％～0.25％,重钙、粉煤灰可替代部分水泥,掺量约7％.生产的粘结剂性能均能满足技术要求和施工需求,且工程应用良好.
Abstract
Through raw material screening,mix ratio design and test,developed a new type of adhesive for exterior wall insulation decorative board with high bond strength,long operational time,anti-freezing and anti-seepage,green environmental protection,safety and non-toxic,simple construction and long service life.The content of polycarboxylic acid superplasticizer is 0.05％,the content of cellulose ether is 0.20％～0.25％,heavy calcium and fly ash can replace part of cement,the content is about 7％.All the performance indexes of the adhesive produced can meet the technical requirements and construction requirements,and the engineering application is good.
