Coating classification: vehicle sound absorption and noise reduction coating

Core tips: Introduction: vehicle noise absorption and noise reduction coatings consist of core shell acrylic IPN emulsion, damping pigments, fillers, flame retardants, auxiliaries, etc the damping composite mechanism is composed of low modulus bottom layer and high modulus surface layer Sound insulation coating is generally damping coating with viscoelasticity When the sound insulation coating is applied on the surface of the object, it will form a high polymer When the external mechanical vibration acts on the polymer, part of the energy will exist in the form of energy storage, while the other part of the energy will be dissipated in the form of heat energy, so as to play a certain role in sound insulation and noise reduction Vehicle sound absorption and noise reduction coating is a high-tech technology Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: Introduction: vehicle noise absorption and noise reduction coating consists of core shell structure acrylic IPN emulsion, damping pigments, fillers, flame retardants, auxiliaries, etc., composed of low modulus of the bottom and high modulus of the surface of the damping composite mechanism Sound insulation coating is generally damping coating with viscoelasticity When the sound insulation coating is applied on the surface of the object, it will form a high polymer When the external mechanical vibration acts on the polymer, part of the energy will exist in the form of energy storage, while the other part of the energy will be dissipated in the form of heat energy, so as to play a certain role in sound insulation and noise reduction Vehicle sound absorption and noise reduction coating is a new type of coating product made by high technology Features: the characteristics of vehicle sound absorption and noise reduction coating are as follows: ① vehicle sound absorption and noise reduction coating is a new type of environmental protection coating with water as solvent, non-toxic, non peculiar smell, non combustion, non pollution, safe and convenient construction; ② the damping performance of vehicle sound absorption and noise reduction coating is good, which can play the role of vibration reduction, noise reduction, noise reduction and sound insulation in a wide temperature / frequency range; ③ The sound absorption and noise reduction coating for vehicles has high solid content and low shrinkage during drying; ④ the sound absorption and noise reduction coating for vehicles can be applied in thick layers with high construction efficiency; ⑤ the dry film of the sound absorption and noise reduction coating for vehicles has good flame retardancy and can withstand gas cutting and welding operations; ⑥ the sound absorption and noise reduction coating for vehicles is firmly attached to steel, aluminum and other base surfaces with good mechanical properties; ⑦ The vehicle sound absorption and noise reduction coating can be applied at the dry wet interface Technical index: the technical index of the project: the coating appearance is easy to mix, no crusting and hard bottom consistency / cm ≤ 10 drying time / h ≤ 48 flexibility / mm ≤ 50 impact resistance / cm ≥ 50 adhesion (grid method) / grade ≤ 2 oil resistance (15d), no over softening, no foaming, no peeling salt water resistance (3% NaCl solution, 15d), no peeling heat resistance (100 ± 2 ℃, 4 h) No sagging, no foaming, no wrinkling, no cracking, low temperature impact resistance (- 40 ± 2 ℃, 4h), no delamination, no cracking, cold heat resistance alternative test (5 cycles), no blistering, no cracking, no falling off 45 ° angle combustion test, fire-resistant grade point / ℃≥ 33 construction performance can be scratched or airless spraying, wet film 3 mm, no sagging composite loss factor 10 ℃ ≥ 0.255, 20 ℃ ≥ 0.139 50 ℃≥ 0.171 80 ℃≥ 0.106 purpose: vehicle sound absorption and noise reduction coating is mainly used for vibration reduction and noise reduction of railway locomotives, buses, automobiles, ships, household appliances, fans, etc it has excellent damping and noise reduction effect at high temperature (- 10 ℃ ~ + 100 ℃) Storage and transportation: the vehicle sound-absorbing and noise reducing coating shall be stored in a cool, ventilated and dry warehouse It is strictly prohibited to rain, sun, isolate the fire source and keep away from the heat source The storage temperature shall be 5-30 ℃ Without opening the original packaging, the storage period of vehicle sound-absorbing and noise reducing coating is 12 months from the date of production If the storage period exceeds, it can be inspected according to regulations If it meets the technical requirements, it can still be used The vehicle sound-absorbing and noise reducing coating shall be transported according to the non dangerous goods specification During transportation, it is strictly prohibited to be exposed to the sun and rain, and shall comply with the relevant regulations of the transportation department 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,
