Abstract

A self-healing environment-friendly penetrating type polymer modified cement-based waterproofing slurry is composed of a liquid material and a powdered material. The liquid material is prepared from, by weight, 550-750 parts of acrylic emulsion, 3-8 parts of defoaming agent, 5-10 parts of dispersing agent, 0.1-3 parts of sterilizing agent and 20-100 parts of deionized water; the powdered material is prepared from, by weight, 200-500 parts of 42.5 grey cement, 100-200 parts of quartz sand of 60 meshes to 120 meshes, 100-300 parts of quartz powder of 200 meshes, 1-5 parts of naphthalene water reducer, 0.5-2 parts of early strength agent, 1-5 parts of rubber powder, 30-70 parts of TC master batches and 8-20 parts of super water absorber. When the waterproofing slurry is used, the liquid material and the powdered material are stirred to be uniform according to the weight ratio of 10:(15-25), and the waterproofing slurry is obtained. According to the self-healing environment-friendly penetrating type polymer modified cement-based waterproofing slurry, the purposes of reaching self healing and environmental friendliness of the waterproofing slurry are achieved mainly by adding the immersing-crystallizing material TC master batches and the super water absorber in the powdered material and introducing the acrylic emulsion with low glass transition temperature into the liquid material; preparation is easy, the cost is low, environmental friendliness and no pollution are achieved, and mass production can be achieved.

Description

technical field [0001] The invention relates to a polymer-modified cement-based waterproof slurry, in particular to a self-healing, environment-friendly and permeable polymer-modified cement-based waterproof slurry. Background technique [0002] The two-component polymer modified cement-based waterproof slurry is a waterproof material with waterproof function formed by the mutual mixing of emulsion, cement and admixture. Its waterproof mechanism is mainly formed through the volatilization of emulsion water and the hydration reaction of cement powder High-strength and tough waterproof coating film, which plays an insulating role between moisture and building structure. Cement-based permeable crystalline waterproof material is a product made of Portland cement or ordinary Portland cement, quartz sand, etc., mixed with active chemical substances. It is a new type of rigid waterproof material. Its mechanism of action is that after it interacts with water, the active chemical su...
