Abstract

The invention discloses waterproof caulking mortar prepared from the following raw materials in parts by weight: 30-40 parts of talc powder, 30-40 parts of tremolite, 5-6 parts of liquid wax, 50-60 parts of fly ash, 30-40 parts of waste diatomite, 3-5 parts of borax, 3-4 parts of ferrous sulfate, 4-6 parts of calcium ammonium nitrate, 2-4 parts of sodium tetraborate, 4-7 parts of used oil, an appropriate amount of water, 20-30 parts of an auxiliary agent, 130-150 parts of cement, 20-25 parts of beta-semi-hydrated gypsum and 170-190 parts of quartz sand. The mortar disclosed by the invention is good in thixotropy, good in leveling property, easy in crack pouring, high in condensation rate, high in bonding strength, non-cracking and good in waterproof property; and 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, in particular to a waterproof caulking 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 ...
