The invention discloses a noise reduction damping fin for a vehicle and a using method, and relates to the technical field of noise reduction damping fins, firstly, the noise reduction damping fin is placed for 7 days at the temperature of 5-35 DEG C and the relative humidity of 50% or below, and the bonding surface needs to be kept clean during bonding, and then the noise reduction damping fin is placed on the surface of the noise reduction damping fin; if the bonding surface is not cleaned, a cloth without fiber falling can be dipped in 50% alcohol, isopropanol or acetone solution to clean the bonding surface, after cleaning is completed, the noise reduction damping fin is attached to the correct position, it is ensured that the noise reduction damping fin and the metal plate surface have enough attaching area, it is ensured that the adhesive surface makes full contact and is wetted, and the bonding surface is pressed; butyl rubber, natural rubber, carbon black, aluminum hydroxide, resin, polyethylene, calcium carbonate and a flame retardant are combined for use, the high damping property of the butyl rubber, the high shock absorption property of the natural rubber and the flame retardant effect of the flame retardant can be utilized, and the butyl rubber, the natural rubber, the carbon black, the aluminum hydroxide, the resin, the polyethylene, the calcium carbonate and the flame retardant are mixed according to a certain proportion; and the effects of isolating and absorbing noise can be effectively achieved.
本发明公开了一种车用降噪阻尼片及使用方法,涉及降噪阻尼片技术领域,首先将降噪阻尼片在5~35摄氏度50%以下相对湿度中放置7天,在进行粘贴的时候先需要保证粘结面清洁,如果不清洁可以用无纤维脱落的布蘸50%浓度的酒精、异丙醇或丙酮溶液对粘结面进行清洁,清洁完成后将降噪阻尼片贴附在正确的位置,确保与钣金面有足够的贴附面积,保证胶面的充分接触和浸润,并按压粘贴表面,确保降噪阻尼片与钣金粘贴固定,通过丁基橡胶、天然胶、炭黑、氢氧化铝、树脂、聚乙烯、碳酸钙、阻燃剂组合使用,可以利用丁基橡胶的高阻尼性,天然胶的高减震性、阻燃剂的阻燃作用,并对其进行按照一定的比例经过混合,可以有效的达到对噪音进行隔绝和吸收的效果。
