Embodiment 1

[0022]

[0023] A natural anhydrite-based light-weight interior wall plastering gypsum material composed of this formula has moderate setting time, fast setting and hardening, and high strength. It has good stability, water retention and sagging during construction; strong bonding performance and good affinity, which greatly improves the adhesion between the product and the substrate; the plastering area is large and has micro-expansion, which eliminates the cracking phenomenon.

Embodiment 2

[0025]

[0026] A natural anhydrite-based light-weight interior wall plastering gypsum material composed of this formula has a relatively fast setting time and fast setting and hardening, which is conducive to mechanized construction. About MPa, it has good stability and water retention for the plastering of concrete walls, aerated blocks or other light wall materials; strong bonding performance, good affinity, good sagging, and shrinkage resistance , with micro-expansion, to prevent cracking.

Abstract

The invention discloses a natural anhydrite based lightweight interior wall plastering gypsum material used in the field of construction, and a preparation method thereof. The natural anhydrite based lightweight interior wall plastering gypsum material is prepared from the following components in percentage by weight: 75-85% of natural gypsum powder, 5-10% of alkali activator, 5-10% of lightweight aggregate, 0.5-2.0% of acidic activator, 0.3-0.5% of water-retaining agent and 0.50-1.0% of cement powder. The preparation method of the natural anhydrite based lightweight interior wall plastering gypsum material comprises the following steps: weighing well-ground gypsum powder based on the weight percentage according to claim 1; uniformly mixing the gypsum powder in a mixer to obtain the natural anhydrite based lightweight interior wall plastering gypsum material. The natural anhydrite based lightweight interior wall plastering gypsum material disclosed by the invention has the advantages of good stability, water-retaining capacity, sagging capacity, large unit plastering area, light weight, heat preservation, good adhesive performance, firm adhesiveness, slight expansibility, convenience for construction, and capabilities of greatly enhancing the adhesiveness between the product and a base material, avoiding undesirable effects such as cracks and realizing both manual construction and mechanized construction.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a natural anhydrite-based lightweight interior wall plastering gypsum material and a preparation method thereof; it is mainly used for interior wall plastering, and can be used for renovation of old houses, concrete walls, various types of plastering Interior plastering of blocks, gypsum blocks or other lightweight wall materials. It has a wide range of applications and has become an indispensable supporting material for construction projects. Background technique [0002] In recent years, there have been common reports on the development of various plastering plasters for interior walls, but they are mainly focused on the development of hemihydrate gypsum, building gypsum, desulfurized gypsum, etc. as base materials. There is still no one to develop light-weight interior wall plastering gypsum materials with my country's abundant reserves and good-grade natural anhyd...
