Novel gypsum-based leveling material

Abstract

The invention discloses a novel gypsum-based leveling material, which is prepared from the following raw materials in percentage by weight: a mixed cementing material, mineral filler, a thickening time control agent, a rheology modifier, latex powder, cellulose ether, slaked lime, a reinforcing material and water, wherein the proportion of the mixed cementing material is 25%-40%, the proportion of the mineral filler is 35%-68%, the proportion of the thickening time control agent is 4%-6%, the proportion of the rheology modifier is 0.4%-0.6%, and the proportion of the latex powder is 1.4%-1.6%. According to the novel gypsum-based leveling material, the mixed cementing material serves as a base material, the mineral filler, the thickening time control agent, the rheology modifier and the reinforcing material are added respectively and stirred, the leveling material is high in forming speed and has high water binding capacity and shrinkage supplementing capacity, by using the leveling material, hollowing and cracking phenomena caused by different materials among different working procedures are avoided, the binding property between the material and other materials is good, and the construction process is simple.

Description

Technical field [0001] The present invention relates to the field of finding a flat material, and more particularly to a new type of gypsyl group to find a flat material. Background technique [0002] Finding is a ground construction process. Finding is the horizontal control line on the wall column and the flat pier is a sign, check the flatness, high shovel, recess the level, shackled with horizontal screw, then surface with wooden If you have a slope requirement, it should be done according to the slope of design requirements. The floor construction process of the decorative decoration project is routinely uses fine stone concrete backfill, cement sander. With the continuous development of science and technology, people's manufacturing technology for finding the materials The requirements are also getting higher and higher. [0003] The existing finding material has a certain drawback, the construction resin self-level or cement composite mortar self-leveling surface, the prob...

Problems solved by technology

[0003] Existing leveling materials have certain disadvantages when used. The construction resin self-leveling or cement composite mortar self-leveling ground, the problem is that there are many construction processes, and different processes may produce hollowing and cracking due to different materials, and Self-leveling materials produce harmful gases such as formaldehyde, benzene, ammonia, etc., which are not conducive to people's use, and have brought certain adverse effects to people's use process. Therefore, we propose a new type of gypsum-based leveling material
