Flame retardant of epoxy resin coating
Epoxy resin coatings were selected and epoxy resin coatings were prepared. The physical properties and corrosion resistance of epoxy coatings were compared, and the curing conditions of epoxy coatings at different temperatures were investigated.
Phosphate is one of the commonly used flame retardants for epoxy resin coatings, most of which belong to additive type flame retardants. Because of its abundant resources, low price and good compatibility with polymers, the phosphate resin is widely used in flame retardant of epoxy resin coatings.
Phosphate series flame retardant: phosphate is the reaction curve corresponding alcohols or phenols and three phosphorus oxychloride, or by alcohol or phenol and phosphorus trichloride reaction and corresponding chloride hydrolysis. The typical varieties are phosphoric acid three phenyl ester, triphenyl phosphate ester, phosphoric acid three (allyl bromide) ester, phosphoric acid three (beta - Lv Yiji) ester, etc..
Epoxy resin coating has excellent corrosion resistance and resistance to chemicals, coatings with good mechanical properties, excellent adhesion to various substrates, and the matching performance of various coatings, can be composed of supporting system and high performance coatings fluorocarbon coating, polyurethane coating, acrylic paint, a long-term anti-corrosion coating.
As a long-term corrosion protection coatings have been widely used in ships, marine engineering and other fields. Epoxy resin contains two active groups of epoxy group and hydroxyl group, which can be made into many kinds of coatings with polyamine, polyamide resin, phenolic resin, amino resin, multi isocyanate resin and so on.
Epoxy resin coatings can be divided into four types according to the curing temperature, namely, low temperature curing agent, room temperature curing agent, medium temperature curing agent and high temperature curing agent.
At present, there are more kinds of curing agents for curing epoxy coatings at home. Epoxy / polyamide curing system has been widely used in heavy corrosion protection fields, such as ships, bridges, oil pipelines, etc..
But, like the traditional amide, application of polyamide curing agent in low-temperature construction is limited, when the temperature is below 10 DEG C, epoxy resin polyamide curing agent with low molecular weight reactions become very slow, although by two ammonia methyl phenol as curing agent, it is possible to obtain low temperature (7 to 10 DEG C) under the curing rate, but, still can not meet the requirement of the construction in winter.

The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
Therefore, it is imperative to prepare epoxy resin coatings which can be used in low temperature conditions to meet the requirements of steel structure building, port machinery, bridges, ships and other large steel structures in winter construction.
Polyaspartic polyurea coating breaks through the bottleneck of short construction activation period, and the activation period can reach 2-3H. It can be applied to many coating fields, such as heavy duty coatings, just like ordinary coatings;
Polyaspartate polyurea coatings as weathering protective topcoat, and traditional zinc rich epoxy primer (inorganic zinc primer), combined with micaceous iron oxide paint, can make the green environmental protection, long-term heavy anti-corrosion coatings in the life of 30 years. It is very suitable for anti-corrosion coating of steel structure, sea crossing bridge, offshore engineering, offshore drilling platform, as well as marine coatings, wind power blade coating, etc..
Polyurea corrosion resistant coating prepared with new structure of poly (aspartic acid) ester as main resin has the advantages of ultra long UV resistance, excellent wear resistance, high solid and low viscosity, long construction period and so on. With the traditional anticorrosion primer / intermediate paint combination can be environmentally friendly long-life anticorrosive paint.
The colors of nature are changeable, but the most basic ones are red, yellow, blue, and three kinds, which are usually called the three primary colors. Another color in the three primary colors according to the different ratio of mixed together, become a complex color. For example, red + yellow = orange; blue + yellow = green; orange and green color is called complex. Complex color color mosaic, another color in the color circle corresponding to the complementary. For example, yellow and blue into green, the corresponding red is complementary to green.
In the color matching, add white color or color dilution, you can get "saturation" of different colors, adding different components of the black, you can get "Brightness" different colors. This will add color tint, and even become gray or black.
Each color can be determined by 3 parameters, namely the hue, lightness and saturation. Hue is the distinguishing feature of color, which is determined by the chromatographic composition of the light source and the feeling of each wavelength emitted by the object surface. It can distinguish red, yellow, green, blue, purple and other characteristics. Lightness, also known as brightness, is the characteristic value of the brightness of the object surface. By comparing the brightness of various colors, the color has a bright and deep dark. Also known as chroma, saturation, feature representation of object surface color shading value, color is bright and dark don't. Hue, lightness, and saturation make up a solid. With these three scales, we measure color with numbers.
