Crosslinking agent for building coatings
Building waterproof materials is an important component of building materials, belongs to the functional materials, buildings and structures to use waterproof material, its main purpose is to moisture, seepage control and leakage protection. China's investment in construction engineering waterproof material is increasing every year.
The annual usage of waterproofing paint in China accounts for about 10% of the total amount of waterproof material, and some areas (for example, the amount of waterproof coating in xiamen) account for about 50% of the total amount of waterproof material. Although the investment in waterproof engineering is very big, but the waterproof effect is not ideal, the leakage rate of the new project is around 10%.
The key is whether the waterproof material has good performance. In recent years, waterproof material research in China has made great progress, has developed the ointment, coil, solvent type viscous fluid, water-based emulsion powder formulations and waterproof material, and has been widely used.
Waterproofing paint for buildings. Waterproof coating is a kind of building waterproof material. Will paint alone or with tire body reinforced material compound, layered coating or coating on the surface of the base that need to be waterproof processing, can be formed under the condition of the continuous seamless whole and has a certain thickness of coating membrane, which can satisfy the industrial and civil architecture roofing, basement, toilet and waterproof impermeability requirements in areas such as the exterior walls.
Waterproof coating is generally composed of asphalt, synthetic polymers, synthetic polymer and asphalt, synthetic polymer and cement or inorganic composite materials as the main film-forming material, mixed with the right amount of pigments, additives, solvents and other processing and made of solvent, the other type or a type of reaction, no fixed shape shape of viscous liquid at room temperature or can be liquefied state of solid powder composite materials containing polymer composite materials.
Waterproof coating, according to its membrane can be divided into asphalt and polymer modified asphalt (also called rubber asphalt class), synthetic polymer class (also can be divided into synthetic resin, synthetic rubber), inorganic and polymer cement and other five categories. According to its state and form, it can be divided into three categories: solvent, reactive and emulsion.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Solvent waterproof coating as the main film-forming material of high polymer material is dissolved in organic solvents (in molecular state exists in) in the formation of the solution as basic material, adding fillers, additives preparation. It depends on the chemical reaction of the volatile or coating components of the solvent, so the construction is basically free from the temperature and can be constructed at lower temperatures. The film structure is compact, high strength and elastic. The waterproof property is superior to the waterproof coating.
However, in the construction and use, there are a lot of inflammable, explosive and toxic organic solvents, which have great harm to the human body and environment, so the application has been gradually restricted in recent years. The main varieties of solvent - based waterproof coatings include solvent - based chloroprene rubber asphalt waterproof coatings, solvent - based chloroprene rubber waterproof coatings, solvent - based chlorosulfonated polyethylene waterproof coatings, etc.
Reactive waterproofing paint as the main polymer material is in the liquid form of prepolymer. Reactive waterproofing coating is a kind of coating which is formed by chemical reaction of liquid polymer prepolymer and corresponding material.
Reactive waterproofing coatings are usually in the category of solvent-based waterproofing coatings, but they are classified as a category because of their particularity. Reactive waterproofing coatings are usually packaged in two components, one of which is divided into mainly membrane-forming substances and the other is generally cross-linking agent. When the two components are mixed, the brush can be painted.
In the process of film forming, membrane material and crosslinking agent react and cross into film. Reactive waterproofing paint is almost free of solvents, and its film resistance, elasticity and aging resistance are generally good, and the waterproof property is also the best of all waterproof coatings. The main varieties of reactive waterproof coatings are polyurethane waterproof coatings and epoxy resin waterproof coatings.
The waterproof coating of epoxy resin is good, but the coating is more brittle, and it is improved with carboxyl butyronitrile rubber, but the price is more expensive and the aging resistance is not as good as polyurethane waterproof coating. The comprehensive performance of reactive polyurethane waterproof coating is one of the best varieties of waterproof coating in China.
