Abstract

The invention discloses light plastering gypsum taking diatomite waste particles as aggregate and a preparation method thereof, and belongs to the technical field of building materials. The diatomitewaste particles used in the invention have the advantages of simple processing process and low processing cost. And when the diatomite waste is treated, the consumption of sand, vitrified micro bubbles and perlite is reduced. Solid waste is utilized, so that the material cost is reduced while environmental friendliness and energy conservation are achieved. The diatomite waste particles used in theinvention have the advantages of light weight, porous micropore structure, air permeability, strong adsorbability and uniform granularity, and the surface of the particles has hydrophobicity after being fully treated by the organosilicon treatment liquid. The plastering gypsum is used as aggregate to be added into light plastering gypsum, is applied to plastering of interior walls, reduces bearing of buildings, adsorbs toxic and harmful gas such as formaldehyde and VOC, purifies air, adjusts indoor temperature and humidity, is breathable, waterproof, mildew-proof and bacteriostatic, has highadhesion to the walls, has excellent leveling effect, is green, energy-saving, healthy and environment-friendly, and has high cost performance, low volume density and high coating rate.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a lightweight plastering gypsum with algal earth waste particles as aggregates and a preparation method thereof. Background technique [0002] With the mining of sand and gravel resources, the natural mineral resources are gradually reduced. With the strengthening of environmental protection control, the mining requirements are getting higher and higher, costing a lot, and causing environmental damage. Traditional plastering materials mainly use sand as aggregate, and the amount of sand used is relatively high. Therefore, replacing sand with particles such as perlite and vitrified beads as aggregate is the development trend of interior wall plastering materials in recent years. [0003] Perlite and vitrified microbeads are relatively common in the market. The raw materials for production are mainly non-renewable natural mineral perlite and turpentine. The ...
