Coating knowledge: understand acrylic polyurethane paint and mechanical paint

Core tip: acrylic polyurethane paint is prepared by waterborne acrylic polyurethane antirust functional emulsion, nano functional materials, rust preventive pigments, inhibitors and auxiliaries It contains no organic solvents, no mercury, lead and other heavy metal anticorrosive pigment with high content Acrylic polyurethane paint combines the advantages of coal tar pitch and epoxy resin, and obtains a good coating with acid resistance, alkali resistance, water resistance, solvent resistance, oil resistance and adhesion, color retention, thermal stability and electrical insulation Mechanical paint, also known as mechanical coating, refers to the coating on the mechanical surface and various machine parts Mainly used in machine tools, equipment, automobiles, hardware, glass Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Coatings home: acrylic polyurethane paint is made of waterborne acrylic polyurethane antirust functional emulsion, nano functional material, rust preventive pigment, corrosion inhibitor and auxiliaries It contains no organic solvents, no mercury, lead and other heavy metal anticorrosive pigment Acrylic polyurethane paint combines the advantages of coal tar pitch and epoxy resin, and obtains a good coating with acid resistance, alkali resistance, water resistance, solvent resistance, oil resistance and adhesion, color retention, thermal stability and electrical insulation Mechanical paint, also known as mechanical coating, refers to the coating on the mechanical surface and various machine parts Mainly used in machine tools, equipment, automobile, hardware, fiberglass and other surface decoration protection acrylic polyurethane paint and mechanical paint common point 1, are two-component industrial paint, including the main paint, curing agent two components, mechanical paint is 2:1 ratio, acrylic polyurethane paint is 4:1 ratio 2 They are very suitable for the use of outdoor machine tools and equipment, that is, they have good weather resistance, good resistance to fading, pulverization and light loss caused by ultraviolet rays, and can adapt to various climatic conditions such as wind, rain, snow, frost, cloudy, sunny, cold and warm 3 The construction method of mechanical paint is basically the same, brush or spray can be used, roll coating is not recommended, and the construction procedures are: paint preparation, curing, viscosity adjustment, construction, inspection, drying, finished product inspection and other steps The aging time and drying time are similar 4 It is used for outdoor steel facility structure, all of which need matching primer and intermediate paint The classic anticorrosive coating is: epoxy zinc rich primer, epoxy micaceous iron intermediate paint and corresponding finish The differences between acrylic polyurethane paint and mechanical paint: 1 Apparent effect For some bright paint effects, mechanical paint is difficult to achieve, while acrylic polyurethane paint is easy to achieve That is, the gloss range of acrylic polyurethane paint is 10-95 °, while that of mechanical paint is about 10-80 ° 2 The difference of outdoor weather resistance, in the same outdoor environment, the use of mechanical paint matching coating, appearance maintenance and rust prevention and corrosion prevention for a longer period of time The anticorrosion period of acrylic polyurethane paint is 7-8 years, while that of mechanical paint is 10-15 years 3 The difference of surface characteristics, mechanical paint has self-cleaning, dust, oil, etc., which is not easy to adhere and clean on the surface of mechanical paint, while acrylic polyurethane paint has no such characteristics Therefore, in haze prone cities, mechanical paint has more advantages Summary: mechanical paint and acrylic polyurethane paint are two kinds of outdoor weather resistant finish paint The difference between them lies in the service life and surface effect In terms of application, acrylic polyurethane paint is widely used in mechanical equipment, engineering vehicles, etc., while mechanical paint is widely used in important, long-term and high decorative steel structure buildings of steel structures, towers and bridges 。 Mechanical paint is widely used in more and more metal coating fields as a kind of high-end industrial paint Industrial paint acrylic series metallic paint is widely used in the surface decoration and protection of various vehicles, various machine tools, plastic machinery, grain machinery, textile machinery, gear reducer, water pump, motor, anti-theft door and other high-demand products Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
