preparation example Construction

[0030] The preparation method of the above-mentioned osmotic crystalline waterproof coating mainly includes: using a planetary mortar mixer, wiping the mixing blade and the mixing bucket with a clean damp cloth before mixing, first mixing the modified siloxane, calcium ion balancer, Add water reducer and water into the mixing tank, then add ordinary portland cement, silica fume, water glass, redispersible latex powder, granulated blast furnace slag, make the mixer rotate at a speed of 57~67r / min, and stir for 20 ~40s; add quartz sand evenly into the mixing tank and continue stirring for 20-40s; stop stirring for 90s, adjust the speed of the mixer to 115-135r / min, scrape the slurry to the middle of the mixing tank, and continue stirring for 50 ~70s, the waterproof coating is obtained.

[0031] The existing cement-based osmotic crystalline waterproof material mainly uses the osmotic crystallization effect of active chemical substances in its composition to achieve the purpose of...

Embodiment 1

[0038] The percentage by weight of each component of the infiltration crystalline waterproof material obtained in the present embodiment is as follows: 56% of ordinary Portland cement, 2% of modified siloxane, 6.2% of quartz sand, 2.2% of silica fume, 3% of water glass, The modulus is 0.5, the redispersible latex powder is 10%, the calcium ion balancer is 0.2%, the water reducer is 0.4%, and the granulated blast furnace slag is 20%.

Abstract

The invention discloses a cement-based capillary crystalline waterproof coating and a preparation method thereof, and belongs to the technical field of building waterproof materials. The cement-basedcapillary crystalline waterproof coating is composed of, by weight, 35%-60% of ordinary Portland cement; 1%-3% of a modified siloxane, 5%-20% of quartz sand, 1.4%-2.4% of silica fume, 1%-5% of water glass, 6.3%-10.8% of redispersible latex powder, 0.2%-1.2% of a calcium ion balancing agent, 0.4%-1.6% of a water reducing agent and 20%-30% of granulated blast furnace slag. By adopting the technicalscheme, the anti-permeability and waterproof performance, the bonding performance and the flexural and compressive strength of the obtained cement-based capillary crystalline waterproof coating can beeffectively improved, the anti-permeability and waterproof effects can be further improved when the cement-based capillary crystalline waterproof coating is applied to the surface of concrete, and therefore the service life of the concrete can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and more specifically relates to a cement-based permeable crystalline waterproof coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the construction industry and the increasing number of underground projects, people have put forward higher requirements for the waterproofing of buildings and the moisture-proof and anti-corrosion materials of underground projects. Building waterproof material is an important part of construction engineering, and its performance directly affects the use function and service life of the building. [0003] Waterproof coatings on the existing market can generally be divided into two categories: rigid waterproof materials and flexible waterproof materials. Among them, the working principle of the flexible waterproof material is: by brushing a certain thickness of waterproof materi...
