Abstract

Plastering mortar is prepared from the following raw materials in parts by weight: 13-17 parts of ethylene-vinyl acetate powder, 30-40 parts of lime, 7-9 parts of lignin fiber, 130-140 parts of cement, 180-200 parts of sand, 20-30 parts of desulphurization ash, 18-23 parts of polypropylene fiber, 10-17 parts of diatomite, 10-14 parts of calcium hydroxide, 13-18 parts of bentonite, 23-28 parts of alumina silicate fiber, 3-5 parts of pine oil, 4-6 parts of sodium metasilicate, proper amount of water, 20-25 parts of an auxiliary agent, and 16-19 parts of redispersable latex powder. The mortar is reasonable in formula, good in compactness, high in bonding strength, small in dry shrinkage deformation, good in cracking resistance, good in workability and water retention, relatively high in adhesive force with a wall material or other base materials after being hardened, and good in endurance. By using the auxiliary agent, the mortar is improved in compression-resistant and rupture-resistant strength and improved in workability, sagging resistance, thixotropy and anti-settlement property.

Description

Technical field [0001] The invention belongs to the field of building materials, and particularly relates to a plaster mortar and a preparation method thereof. Background technique [0002] Mortar is a common material used in construction and is an essential material in construction. According to the performance classification, there are many kinds of mortar, including combined mortar, caulking mortar, thermal insulation mortar, etc.; according to the purpose, it is divided into masonry mortar, plastering mortar (including decorative mortar, waterproof mortar), bonding mortar, etc. [0003] At present, the performance and quality of mortar are different, which affects the use. Specifically, the factors that affect the performance of the mortar include the workability, fluidity, water retention of the fresh mortar, and the strength of the hardened mortar. It is necessary to study new mortars with excellent workability and processability, anti-sagging properties, thixotropy, anti-s...
