Machine-sprayed light bottom plastering gypsum and preparation method thereof
The invention discloses machine-sprayed light bottom layer plastering gypsum. The machine-sprayed lightweight bottom plastering gypsum comprises the following components in parts by weight: 1.5-5 parts of a curing agent, 2-5 parts of a retarder, 10-25 parts of a water-retaining agent, 20-40 parts of glass beads, 0.1-0.5 part of pre-gelatinized starch, 400-600 parts of water and optionally, an accelerant based on 100 parts of pretreated phosphogypsum. The invention further provides a preparation method of the machine-sprayed light bottom plastering gypsum. The various mechanical properties of the prepared machine-sprayed light bottom plastering gypsum meet the requirements, and the problem that common plastering gypsum cannot be mechanically constructed is solved; manual plastering is replaced by mechanical plastering, so that the construction efficiency can be greatly improved, and the construction period is shortened; and the construction process is simple.
本申请公开了一种机喷轻质底层抹灰石膏，所述机喷轻质底层抹灰石膏包括：以预处理的磷石膏为100份计，固化剂1.5‑5份，缓凝剂2‑5份，保水剂10‑25份，玻化微珠20‑40份，预糊化淀粉0.1‑0.5份，水400‑600份以及任选地，促进剂。本申请还提供所述机喷轻质底层抹灰石膏的制备方法。制备出的机喷轻质底层抹灰石膏的各项力学性能均满足要求，解决了普通抹灰石膏无法机械化施工的难题；机械化抹灰代替人工抹灰，可以大大提高施工效率，缩短工期；施工工序简单。
