Gypsum-based high-strength dry-mixed masonry mortar and preparation method thereof
The invention belongs to the field of gypsum-based masonry mortar, and particularly relates to gypsum-based dry-mixed masonry mortar and a preparation method thereof. The ardealite base material is adopted to replace common masonry mortar on the market, most of traditional masonry mortar is cement-based, high in shrinkage rate, large in brittleness, poor in deformation adaptability and prone to hollowing, when the masonry base layer is a gypsum-based material, soluble sulfate in gypsum reacts with components in the cement-based ceramic tile adhesive, and therefore the cement-based ceramic tile adhesive is formed. The problems of hollowing, cracking, brick falling and the like caused by internal volume expansion of the material due to delayed ettringite which is generated in the prior art are solved, and the phenomena are more obvious in case of moisture regain, water seepage and the like. Therefore, the gypsum-based dry-mixed masonry mortar matched with the ardealite base material is developed, and the gypsum-based dry-mixed masonry mortar is high in bonding strength, low in shrinkage rate, free of hollowing and cracking and high in cost performance, and forms a complete industrial chain with an ardealite product system mainly pushed in the market, so that the worry of customers at application ends on selecting ardealite building material products is eliminated.
本发明属于石膏基砌筑砂浆领域，具体涉及一种石膏基干混砌筑砂浆及其制备方法。本发明采用磷石膏基材代替市面上普通砌筑砂浆，传统砌筑砂浆多为水泥基，收缩率高，脆性大，变形适应性差，易空鼓，当砌筑基层为石膏基材料时，石膏中的可溶性硫酸盐与水泥基瓷砖胶粘剂中的成分发生反应，会产生延迟钙矾石导致材料内部体积膨胀，造成空鼓、开裂、掉砖等问题，若遇到返潮、渗水等情况，此现象更为明显。因此，开发出一款与磷石膏基材配套的石膏基干混砌筑砂浆，粘接强度高、收缩率低、不空鼓不开裂、性价比高，与市场上主推的磷石膏产品体系形成完整产业链，从而消除应用端客户选择磷石膏建材产品的顾虑。
