Abstract

The invention belongs to the technical field of building-use waterproof materials and particularly relates to a quick-drying and quick-hardening polymer cement waterproof slurry material and a preparation method thereof. The quick-drying and quick-hardening polymer cement waterproof slurry material includes a liquid material and a powdery material according to a weight ratio of 1:3-4. The liquid material is prepared from following raw materials, by weight: 35-50 parts of a polymer emulsion and 0.05-0.2 parts of a defoaming agent. The powdery material is prepared from following raw materials, by weight: 30-60 parts of sulphate aluminium cement in 42.5 grades, 35-60 parts of quartz sand in 70-200 meshes and 0-10 parts of heavy calcium carbonate in 320 meshes. The slurry material is quick in hardening, is strong in early strength, is good in early water resistant performance, allows an impoundment test to be performed in advance for reducing construction period, is high in adhesive strength with a base material, is green and environmental-protective, and can be used for waterproofing and leakage resistance on various base materials and wall bodies.

Description

(1) Technical field [0001] The invention relates to the technical field of building waterproof materials, and in particular relates to a quick-drying and quick-hardening polymer cement waterproof slurry and a preparation method thereof. (2) Background technology [0002] Polymer cement waterproof slurry has good fluidity, strong coagulation with the base layer, high resistance to osmotic pressure, and good durability. It is a water-based environmental protection material and is usually used in waterproof and moisture-proof projects for buildings. However, the traditional polymer-modified cement-based waterproof slurry cannot meet the requirements of rapid construction. After construction and brushing, it is necessary to wait for the cement to solidify for 3 days before the water storage test can be carried out. After passing the acceptance, the next process can be carried out. Sulphoaluminate cement is used as the main inorganic cementitious material, and cement early streng...
