Yellow River sand thermal insulation dry-mixed mortar for interior wall and preparation process thereof
The invention relates to dry-mixed mortar, in particular to Yellow River sand thermal insulation dry-mixed mortar for an inner wall and a preparation process thereof. The invention discloses Yellow River sand heat-insulation dry-mixed mortar for an inner wall and a preparation process thereof. The preparation process comprises the following steps: performing surface modification pretreatment on Yellow River sand; preparing an acrylic acid-urea resin blended emulsion; spraying and wrapping the glass beads with the blended emulsion; coating the modified water-quenched manganese slag with the styrene-acrylic-organic silicon emulsion; enhancing and modifying the polypropylene fiber; and preparing the thermal insulation dry-mixed mortar. The acrylic acid-urea resin blended emulsion is used for spraying and wrapping the glass beads, a thin film with high crosslinking density can be formed on the glass beads, the styrene-acrylic-organic silicon emulsion is used for coating and modifying the water-quenched manganese slag, a water-resistant thin film can be formed on the surface of the water-quenched manganese slag, and the modified water-quenched manganese slag is doped into the thermal insulation mortar, so that the thermal insulation mortar has good thermal insulation performance. Part of space of the glass beads is occupied, the interface area between the glass beads and a cement paste base body is reduced, air holes are reduced, and therefore the compressive strength of the mortar is improved.
本发明涉及干粉砂浆，具体涉及一种内墙用黄河砂保温干粉砂浆及其制备工艺。一种内墙用黄河砂保温干粉砂浆及其制备工艺，包括以下步骤：黄河砂表面修饰预处理；配置丙烯酸‑脲醛树脂共混乳液；共混乳液对玻化微珠的喷涂包裹；苯丙‑有机硅乳液包覆改性水淬锰渣；聚丙烯纤维的增强改性；保温干粉砂浆的配置。本发明使用丙烯酸‑脲醛树脂共混乳液对玻化微珠进行喷涂包裹，能够在玻化微珠形成交联密度高的薄膜，使用苯丙‑有机硅乳液对水淬锰渣进行包覆改性，能够在水淬锰渣表面形成耐水性薄膜，使用改性后的水淬锰渣掺入保温砂浆中，占据玻化微珠的部分空间，减小玻化微珠与水泥浆基体之间的界面面积，减少气孔，从而提高砂浆的抗压强度。
