Deep-layer active micro-powder masterbatch for moisture-proof building ground floor

Abstract

The invention discloses a deep-layer active micropowder masterbatch for dampproofing the ground floor of a building. The micropowder masterbatch comprises the following components in parts by weight: 2 to 6 parts of acrylic polysiloxane, 2 to 6 parts of active silicone zirconium, 2 to 8 parts of calcium magnesium carbonate, 1 to 5 parts of methyl cellulose, 60 to 90 parts of silicon micropowder, 0.3 to 1 part of sodium silicate, 0.5 to 1 part of expansion agent, 0.3 to 0.6 parts of water reducer, defoamer 0.3 to 0.8 parts, the present invention has the effect of preventing ground tide, making the interior of the room comfortable and dry, moisture-proof and mildew-proof of articles, thereby prolonging the service life.

Description

technical field [0001] The invention relates to the field of building moisture-proof materials, in particular to a deep active micropowder masterbatch for building ground floor moisture-proof. Background technique [0002] Moisture return on the ground is a common problem in living on the first floor or in the basement at home. Especially in the south and south winds, the moisture return on the ground and walls is particularly serious. , breeds a lot of bacteria. Moisture on the ground in factories and other places will cause foaming and cracking of the floor, which will deteriorate the product. At present, for moisture-proof phenomenon, people generally take corresponding moisture-proof treatment. But people tend to confuse the concepts of moisture-proof and waterproof, and often use waterproof materials and construction methods to deal with moisture-proof problems. This will not only fail to obtain a good moisture-proof effect, but will eventually cause irreparable cons...

Problems solved by technology

However, people tend to confuse the concepts of moisture-proof and waterproof, and often use waterproof materials and construction methods to deal with moisture-proof problems

This will not only fail to get a good moisture-proof effect, but will eventually cause irreparable consequences; this is because the moisture-proof solution is to prevent moisture or water vapor from entering the room, and the waterproof solution is to prevent liquid water from penetrating into the room. Waterproof The molecular density of the layer is difficult to prevent the passage of water vapor

[0003] A Chinese invention patent with the publication number CN107119728A discloses a basement construction process and a three-proof microcrystalline additive powder for the basement, including the following components by weight: 2-4 parts of meteorological silica, expansion agent 5-7 parts, 0.1-0.5 parts of calcium formate, 1-3 parts of sodium sulfate, 0.1-0.5 parts of water-reducing agent and 0.1-0.3 parts of water-retaining agent, effectively keeping the basement dry and avoiding damp, leakage and mildew in the basement phenomenon, but the conditions of use are limited, and the problem of ground tide infiltration and upward movement on the ground floor of existing old houses and new residential buildings still cannot be well solved
