Waterproof coating is used crosslinking agent
Along with the progress of science and technology and the development of chemical building materials industry, waterproof coating has gained rapid development, so far, a patent for invention mainly about waterproof coating is two components and one-component polyurethane waterproof coating, (modified) modified polyacrylate waterproof coating, waste material is waterproof coating, neoprene waterproof coating and polymer cement waterproof coating and polymer modified asphalt waterproof coating and inorganic waterproof coating, etc., to form the chemical crosslinking reaction and the solvent (including water) volatile drying performance, such as different, different forms of multi-type, many varieties of pattern.
Emulsion waterproofing paint is a single - component water - emulsion waterproofing paint. Paint is brushed on the building, as the water evaporates into the film. The emulsion type waterproofing paint is mainly made of membrane material, which is suspended in water by extremely small particles and becomes a emulsion coating.
Simple and convenient construction technology for the coating, film is accomplished by moisture volatilize and emulsion particles merge, no organic solvent escape, no pollution, no combustion, construction safety, its price is cheaper, waterproof performance can basically meet the needs of construction projects, is the developing direction of the waterproof coating.
There are many kinds of emulsion waterproof coatings, mainly including: water emulsion type cationic neoprene rubber asphalt waterproof coating; Waterproofing paint for water-emulsion regenerated rubber asphalt; Polyacrylate emulsion waterproofing paint; EVA (ethylene - vinyl acetate copolymer) emulsion waterproofing paint; High water emulsion polyurethane waterproof coating; The organic silicon modified polypropylene ester emulsion waterproof coating etc.
According to the composition of waterproofing paint, it can be divided into two categories: one-component waterproof coating and two-component waterproof coating. The one-component waterproof coating is different in liquid form, in general, there are two types of solvent and water emulsion. The two-component waterproof coating is mainly reactive type.
The building waterproof coating is different according to its use on the building, can be divided into roofing waterproof coating, facade waterproof coating, waterproof coating of underground engineering and other kinds.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
Waterproof coating variety, but its waterproof mechanism can be divided into two categories, one is the coating type, the second is hydrophobic type.
Coating waterproofing paint is waterproof by forming a complete coating to block the water through or through the infiltration of water molecules. Many molecules and molecules of polymer film, there is always some gap between its width is about several nanometers, arguably, is fully capable of through a single water molecule, but the nature of water usually is in a state of association, dozens of due to the effect of hydrogen bonding between water molecules to form a group of large molecules, so is, in fact, it is difficult to by polymer clearance, this is the main reason for the waterproof coating film has the function of waterproof.
Because some polymer molecules contain hydrophilic groups, the complete continuous coating formed by polymer does not guarantee that all polymer coatings have good waterproof properties. If the polymer itself with hydrophobic properties, fundamental incompatibility between water molecules and the coating, it can fundamentally solve the problem of the water molecules through, polysiloxane waterproof coating is designed according to this principle.
Development of polymer modified asphalt waterproof coating and synthetic polymer waterproof coating, and development of inorganic powder of permeable crystallization type waterproof coating and other varieties, and is developing towards environmental protection is waterproof coating.
Acrylic polymer and vinyl polymer hydroemulsion waterproofing paint, in which the emulsion contains at least 40 % of acrylic and vinyl polymers, and the volume concentration of titanium dioxide is no more than 10%. The waterproof coating is mainly used for the waterproofing of roofing and exterior walls. The coating is highly elastic. The waterproof coating is a durable waterproof coating, which can be used for at least 10 years.
