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, in particular to a plastering mortar and a preparation method thereof. Background technique [0002] Mortar is a common material for construction and is an essential material in construction. According to performance, mortar can be divided into many types, such as combined mortar, caulking mortar, thermal insulation 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 mortar include the workability, fluidity, water retention of freshly mixed mortar, and the strength of hardened mortar. New mortars need to be researched to have excellent construction and processability, sag resistance, thixotropy, anti-settling properties, storage stability, improved pumpability and shear thinning, and new materials need to be found , in order to improve its performance and strength, and reduce th...
