Lightweight internal wallboard additive and preparation method thereof
The invention discloses a light interior wallboard additive and a preparation method thereof. The light interior wallboard additive comprises cellulose ether, calcium oxide and a waterproof agent, the calcium content in calcium oxide is not less than 85%; the cellulose ether is hydroxypropyl methyl cellulose (HPMC); the mass of the cellulose ether accounts for 15-25% of the mass of the light interior wallboard additive; the mass of the calcium oxide accounts for 55-65% of the mass of the light interior wallboard additive; the mass of the waterproof agent accounts for 15-25% of the mass of the light interior wallboard additive; according to the additive for the light inner wallboard, the synergistic effect of the three materials of the cellulose ether, the calcium oxide and the waterproof agent is exerted, the dry shrinkage value of the light inner wallboard can be reduced, the flexibility is obviously improved, and the light inner wallboard does not generate any crack after being installed.
本发明公开了一种轻质内墙板添加剂及其制备方法，轻质内墙板添加剂包括：纤维素醚、氧化钙和防水剂；氧化钙中的钙含量≥85％；纤维素醚为羟丙基甲基纤维素HPMC；纤维素醚的质量占轻质内墙板添加剂的质量百分比为15％‑25％；氧化钙的质量占轻质内墙板添加剂的质量百分比为55％‑65％；防水剂的质量占轻质内墙板添加剂的质量百分比为15％‑25％；本发明的轻质内墙板添加剂发挥纤维素醚、氧化钙和防水剂三种材料的协同作用，可以使轻质内墙板干收缩值减小，柔性明显提高，使轻质内墙板安装后不产生任何裂纹。
