Abstract
The utility model relates to an auto part, in particular to car A post sound insulation expansion glue strip. The utility model discloses a realize above -mentioned mesh, including nylon buckle, EVA foam sheet, EVA foam sheet be the strip, and foam sheet's both ends pass through that the nylon buckle is fixed to constitute a ring -type together, leave one section EVA foam sheet in the ring -type, and the front end of the nylon buckle after fixing stretches out outside the annular EVA foam sheet. The utility model discloses a characteristics are: device location accuracy, simple to operate, the effect that gives sound insulation are obvious, and the density behind the high temperature expansion is very low, is difficult for droing during the product use, safe and reliable.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, particularly a kind of automobile A column sound insulation expansion adhesive tape.
Background technology
Along with the progress of auto manufacturing technology, people more and more pay close attention to the control of manned vehicle internal car noise and vibration, and the level of control of internal car noise has become one of important symbol weighing manned vehicle quality.When galloping, automotive front end A post is ventilation inlet, and produce high velocity air, high velocity air and sheet metal component rub and produce strong roar, have a strong impact on the comfort of driver and passenger.Traditional solution is at materials such as automobile A column filling sponge or expansion films, but these materials are limited for the control effects of noise, and is difficult to fix, and often come off inefficacy, can not effectively reduce the noise produced in running car.Therefore how effectively closed car A post, blocks air-flow and passes through, become a puzzlement automobile design developer's difficult problem.
Summary of the invention
For problems of the prior art, the utility model provides and a kind ofly assembles simple, that good airproof performance, effect of vibration and noise reduction are good automobile A column sound insulation expansion adhesive tape.
The utility model for achieving the above object, the technical scheme adopted is: a kind of automobile A column sound insulation expansion adhesive tape, it is characterized in that: comprise nylon buckle, EVA foam sheet, described EVA foam sheet is strip, the two ends of foam sheet to be fixed together formation ring-type by nylon buckle, in ring-type, leave one section of EVA foam sheet, the front end of the nylon buckle after fixing is stretched out outside the EVA foam sheet of ring-type.
Feature of the present utility model is: device accurate positioning, easy for installation, soundproof effect are obvious, and density after high-temperature expansion is very low, difficult drop-off when product uses, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, structure of the present utility model is described further.
Consult shown in Fig. 1, a kind of automobile A column sound insulation expansion adhesive tape, comprise nylon buckle 1, EVA foam sheet 2, EVA foam sheet 2 is strip, the two ends of EVA foam sheet 2 to be fixed together formation ring-type by nylon buckle 1, in ring-type, leave one section of EVA foam sheet 2, the front end of the nylon buckle 1 after fixing is stretched out outside the EVA foam sheet 2 of ring-type.
During use, by the front end of nylon buckle of stretching out outside the EVA foam sheet of ring-type, be inserted in the auxiliary hole internal fixtion on automobile A column panel beating, automobile is by after the high-temperature baking of Painting Shop electrophoresis operation, EVA foam sheet starts to expand and fills full vehicle body A post cavity, thus intercept air flowing, achieve the object reducing noise.
EVA foam sheet be by EVA resin, foaming agent, crosslinking agent, extending agent through mixing, banburying, extrude, roll, the step such as stamping-out is shaping, at 140 ~ 200 DEG C, 30min is expanded foamed, and expansion ratio is between 6 ~ 30 times.
The size dimension of the size of automobile A column sound insulation expansion adhesive tape, size and automobile A column adapts, and the size dimension according to automobile A column designs.
