Polyamide type epoxy resin coatings crosslinking agent
2017-4-1 15:14:23
Polyamide type epoxy resin coatings crosslinking agent, by the reaction of tung oil acid and multiple amine tung oil acid dimers multivariate amine, due to the structure containing long carbon chain fatty acid and amino, can make the crosslinking products with high elasticity and sticky relay and water resistance.
Polyamide type epoxy coatings cross-linking agent construction performance is good, ingredient proportion is wide, small toxicity, basic no volatile matter, can in the damp of the surface of the metal and concrete construction, the disadvantage is that crosslinking slower, low heat resistance, low thermal deformation temperature, gasoline, hydrocarbon solvent resistance is poor.
Polyamide is a main chain macromolecules unit the floorboard of the polymer containing amide groups. Polyamide acid amine can be from inside the ring opening polymerization system, and also can be obtained by diamine and dibasic acid polycondensation. In the 1950 s the development and production of injection molding products, to replace the metal to meet lightweight downstream industrial products and reduce cost.
Polyamide has good comprehensive performance, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and low friction coefficient, have certain flame retardant, easy processing, suitable for reinforced with glass fiber and other packing, improve performance and expand the application range.
The variety of color change is endless, gorgeous, but all sorts of color and there exists a certain internal relation between coating color is also. In addition to the protective coating anticorrosive and some special functions such as such as mildew, conductive, noise reduction, the main function is the home decorated with colorful life breath.
Due to the nature of each color has a alone, it for people's visual and psychological, physiological and so on all have a strong sense of different effects, let's meet some basic knowledge of the coating color and how to mix colors.
Each color can be used to determine the three parameters, namely the hue, lightness and saturation. Tone is characteristic of color difference between each other, determine the guang-yuan yu of chromatography and the wavelengths emitted by an object's surface to the human eye feeling, can be the difference between red, yellow, green, blue, purple etc. Characteristics. Lightness, also known as the brightness, it is said the eigenvalues of the objects on the surface of light and shade degree change, by comparing the brightness of all sorts of color, color is bright and dark. Saturation, also known as chroma, it is said the surface color shades of characteristic value, the colour with bright and dark. Hue, lightness and saturation constitute a three-dimensional, with the three established scale, we will use a number to measure color.
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
A kaleidoscope of colors in nature, but the most basic is red, yellow, blue, and three, often referred to as trichromatic color. In the three primary colors according to the different proportion mixing mixture of another color, complex color. For example, red + yellow = orange; Blue + yellow = green; Called orange and green color. Three primary colors of the complex color, its corresponding in the color ring another color for compensation. For example, green, yellow and blue Mosaic of red is the color of green.
In color, add white color or multicolor dilute, "saturation" are available on different color, adding different amount of black, "lightness" different kinds of color can be obtained. Complementary color add to the complex color can make to a dark, even into a gray or black.
For aromatic amine or aromatic amine, primary, secondary and tertiary amine electronic effect, space effect, the influence of the solvation effect of these three aspects result is unified. Such as: aniline, diphenylamine, three benzene
Amine, alkaline pecking order for:
NH3 > NH2 > () 2 nh > (3) n
Three aniline using hot concentrated hydrochloric acid can generate salt, it has almost neutral.
Therefore, considering the same kind of amine (fatty amines, aromatic amine) of primary, secondary and tertiary amine in aqueous alkali strength, must take the solvation effect, electronic effect and space effect.
