Problems solved by technology

However, this scheme uses a large amount of organic solvents, which is not friendly to the environment
As for the research on water-based protective agents, it is generally applied to the exterior walls of buildings and the surfaces of various substrates to have a good hydrophobic effect, but little is involved in the permeability of products.

Embodiment Construction

[0050] Below by embodiment the present invention will be further described:

[0051] Table 1 The raw material composition mass percentage of silicone emulsion in the embodiment

[0052]

[0053] Preparation:

[0054] According to the ratio of raw materials in Table 1, firstly add stabilizer and surfactant into water, mix well to obtain solution A; then add polysiloxane, nano silicon dioxide, penetration enhancer to alkoxysilane, mix well Obtain B solution;

[0055] Under high-speed dispersion conditions, add solution A dropwise into solution B; maintain high-speed dispersion during the dropping process. During high-speed dispersion, the dispersion speed of solution A is 2000rpm, and the dropping speed of solution A is 5-15g / min·kg. After completion, a white milky liquid with stable performance is formed, which is the stock solution of penetrating silicone protective agent.

[0056] Brush the above emulsion on the surface of fly ash masonry, 95 blue bricks and C30 concret...

Abstract

The invention discloses a permeation type organosilicone emulsion for the surface of a building and a preparation method of the permeation type organosilicone emulsion. The permeation type organosilicone emulsion consists of the following ingredients in percentages by mass: 30.0-45.0 parts of alkoxy silane, 10.0-15.0 parts of polyorganosiloxane, 2.0-5.0 parts of fluoroalkyl silane, 0.5-1.0 part of a permeation enhancer, 3.0-6.0 parts of a surfactant, 1.0-2.0 parts of a stabilizer and 20.0-45.0 parts of deionized water. The waterborne organosilicone emulsion disclosed by the invention has good permeation depth on fly ash masonry, 95 black bricks and C30 concrete structures, water absorbing amount of concrete is reduced effectively, and alkali resistance and ultraviolet light resistance are excellent. The permeation type organosilicone emulsion for the surface of the building is convenient to prepare, stable in storage, environmentally friendly, convenient to use and high in durability.

Description

technical field [0001] The invention relates to a building material, in particular to a penetrating organic silicon protective agent for building surfaces and a preparation method for the protective agent. Background technique [0002] Compared with other coating waterproof materials, organic silicon protective agent materials for building surfaces have many advantages such as excellent aging resistance, obvious hydrophobic effect, and excellent air permeability. They have been widely used in building materials, bricks, mortars, ceramic tiles, etc. base material surface. [0003] There are many kinds of decorative materials for interior and exterior walls of buildings. These materials use cement, lime calcium, gypsum, etc. as the skeleton to gel other components, and form functional materials with different properties under the combined action of various additives. These materials have different properties and have been widely used in interior and exterior wall decoration, ...
