Problems solved by technology

[0003] The raw materials of water-based damping slurry usually include liquid and solid materials. In the traditional production process of damping slurry, a large amount of dust will be generated during the transmission of solid powder materials and the process of solid-liquid mixing and stirring. Dust not only pollutes the environment, but also affects the health of operators. Unfavorable, and there will be certain safety hazards if the dust concentration is too high, so the process of producing damping slurry needs to be optimized

Abstract

The invention provides a production technology of waterborne damping slurry. The production technology includes the concrete steps that a liquid-state raw material is conveyed to a mixing machine through liquid conveying equipment, a solid raw material is weighed and put into a dust-free feeding station and conveyed to the mixing machine through a pneumatic conveying system to be mixed with the liquid-state raw material, and the materials are mixed uniformly, then weighed, subpackaged and output through a belt. Integrated design and a control mode of combining with on-site conventional operation are adopted in the production process to form a complete collecting, control and management system. By means of program setting and received in-place signals, feeding, mixing and discharging actions are completed continuously and stably, dust flying is avoided in the production process of feeding, conveying and stirring the powder material, and the production environment is improved.

Description

technical field [0001] The invention belongs to the field of materials and relates to a production process of water-based damping slurry. Background technique [0002] Damping slurry (damping coating) uses the viscoelastic properties of organic polymer materials to convert the mechanical vibration energy of sound waves into heat energy and release it (ie mechanical loss), so as to achieve the purpose of reducing amplitude, reducing vibration and suppressing noise. Water-based damping coating has the advantages of good flame retardancy, high adhesion, corrosion resistance, aging resistance, high damping performance and convenient construction. It is currently being widely used in automobiles, trains, ships, aircraft, construction machinery and other household products. In the field of electrical appliances, it plays the role of sound insulation, sound absorption, shock absorption and heat preservation. [0003] The raw materials of water-based damping slurry usually include ...
