Abstract
The invention discloses waterproof heat insulation environment-friendly mortar prepared from the following raw materials in parts by weight: 5-8 parts of silicon carbide, 20-24 parts of aluminum oxide micro powder, 20-30 parts of a polyacrylate emulsion, 20-25 parts of silicon micro powder, 100-130 parts of perlite, 80-100 parts of tourmaline negative ion powder, 2-4 parts of stearic acid, an appropriate amount of water, 20-25 parts of an auxiliary agent and 130-140 parts of cement. The mortar disclosed by the invention is excellent in adhesion, crack resistance, frost resistance, seepage prevention, corrosion protection, chlorine ion penetration resistance, aging resistance and corrosion resistance; by using the tourmaline negative ion powder, the mortar is beneficial for human health, has good heat insulation property, and is suitable for anti-seepage, anticorrosive face protection and repair engineering of steel structures and reinforced concrete structures including industrial terraces, civil buildings and the like. By using the auxiliary agent provided by the invention, the compression resistance and breaking strength of the mortar are improved, and the workability, sagging resistance, thixotropy and sedimentation resistance of the mortar are also improved.
Description
technical field [0001] The invention belongs to the field of building materials, and in particular relates to a waterproof, heat-preserving and environment-friendly 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 ...
