Application And Development Of Environmental Hot Melt Damping Material

Damping damping products,is a polymer material,can reduce the mechanical equipment in the process of running the noise generated.In the introduction,the damping mechanism of viscoelastic materials is mainly started,and the effect is analyzed.Viscoelastic material damping effect occurs because of its external force in the effect of a certain lag phenomenon,the loss of force;In general,the damping effect of the measurement,the main use of the loss factor to judge.The viscoelastic material of this index is much higher than other materials,it is often used to produce damping materials.In this paper,the commonly used damping materials are studied in detail by discussing the hot-melt damping pads.In this paper,the preparation of non-asphalt hot-melt damping pad was carried out in industrial design,In the preparation of damping materials,the appropriate viscoelastic material butyl rubber was determined,and the butyl rubber was used as the main material for the formulation design and the matching agent,Through the continuous testing of the formula to improve,and no asphalt green thermal damping pad design a series of performance requirements and a detailed test.And finally determine the most appropriate program,The final formula is the main material is butyl rubber,ingredients are some match agent.The main process of preparation is the preparation of butyl hot melt damping compound,extrusion,extension,cooling and standing operation,and finally through the blanking to obtain the final product.In this paper,the production of non-asphalt hot-melt car damping pad has been designed in detail and has been industrialized.The production of non-asphalt green damping materials has a more practical significance.No asphalt hot-melt damping board,is a use of butyl rubber materials made of damping materials,with environmentally friendly,good quality advantages.
