Problems solved by technology

[0003] However, the traditional leveling mortar is only suitable for the renovation, repair and leveling of various cement bases, and the construction process is complicated and cumbersome, requiring closed site→base level inspection→base level treatment→painting self-leveling interface agent→preparing slurry→paving self-leveling A series of processes such as leveling slurry→deflation→maintenance→finished product protection have brought great inconvenience to the construction party. After the leveling mortar construction is completed, waterproof layer construction is required

Abstract

The invention relates to the field of building materials, and specifically discloses a leveling mortar with a waterproof function, which includes the following components: cement, polytetrafluoroethylene micropowder, renewable latex powder, fumed silica, aggregate, metakaolin, powder dispersant Foaming agent, cellulose ether, powder water repellent, wood fiber, water reducer. The invention provides a leveling mortar with a waterproof function. By adding polytetrafluoroethylene micropowder and redispersing rubber powder, it can achieve a reasonable surface hydrophobic effect and at the same time have a leveling function, which solves the problem that the leveling mortar has no waterproof effect It realizes the integration of waterproofing and leveling, eliminating the need for another step of waterproofing after leveling, improving construction efficiency and saving costs.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a leveling mortar with waterproof function. Background technique [0002] Leveling mortar is a dry-mixed powdery material composed of a variety of active ingredients. It can be used directly after mixing with water on site. During construction, it can be spread out with a scraper to obtain a high-level base surface. The leveling mortar has a fast hardening speed, and it can be walked on within 24 hours, or follow-up projects (such as laying wood floors, diamond boards, etc.), and the construction is quick and easy, which is incomparable to traditional manual leveling. [0003] However, the traditional leveling mortar is only suitable for the renovation, repair and leveling of various cement bases, and the construction process is complicated and cumbersome, requiring closed site→base level inspection→base level treatment→painting self-leveling interface agent→preparing slurry→pav...
