As preferably, the radial distance between described outer thermal expansion pipe and the interior thermal expansion pipe is 10 millimeters to 20 millimeters.Adopting said structure is according to the size design of vehicle side cavity, helps whole gusset cavity cross section complete filling.
As preferably, described outer thermal expansion pipe is the body that is made up of epoxy resin low bulk reinforcing material, and pipe thickness is 1.5 millimeters to 3 millimeters.Adopt this structure mainly to be because the volume expansion ratio of epoxy resin low bulk reinforcing material and cavity size decision, epoxy resin low bulk reinforcing material is at 160 degrees centigrade to 180 degrees centigrade, complete foaming and intumescing after 20 minutes; Volume increases, and after the increase, volume expansion ratio is 0.5 to 3; The hardened material sclerosis strengthens; Mainly to the humidification of cavity panel beating, too thinly can not play humidification to the cavity panel beating, the too thick waste that is prone to cause material.
As preferably, described in the thermal expansion pipe be the body that constitutes by EVA or EPDM foam material, pipe thickness is 1.5 millimeters to 6 millimeters.Adopt this structure mainly to be because the volume expansion ratio of foam material and cavity size determine; EVA or EPDM foam material are at 160 degrees centigrade to 180 degrees centigrade; Complete foaming and intumescing after 20 minutes, volume expansion ratio is 5 to 20, plays the obstruction seals cavity and absorbs the cavity noise.
As preferably, insulator is the V font stake body that is made up of aluminium foil, offers many holes on the aluminium foil, and the porosity ratio of aluminium foil is 50/square centimeter to 100/square centimeter
,Aluminium foil mainly plays heat-blocking action, and inside and outside thermal expansion pipe is convenient in perforate and insulator is integrally formed.
As preferably, the angle of insulator V font stake body is that 30 degree are to 120 degree.This is to determine according to radial distance between the thermal expansion pipe and pipe thickness inside and outside the Sealing, can bring into play the heat-blocking action of insulator more fully.
As preferably, the quantity of alloy skeleton and insulator is 6 to 12.Quantity causes the waste of material too much, and quantity is unfavorable for better playing a supporting role very little.
As preferably, link is the seizing type fixed block.Can be easily Sealing be installed in the vehicle side cavity on the corresponding panel beating through the seizing type fixed block.
The beneficial effect of the utility model is: adopt technique scheme; Through special loop configuration, by the interior thermal expansion tube swelling foaming that EVA or EPDM foam material constitute, the outer thermal expansion tube swelling foaming sclerosis that is made up of epoxy resin low bulk reinforcing material strengthens; Sealing integral body is with applied cavity cross section complete filling; The alloy skeletal structure is adopted in the intermediate portion, and the skeleton resistance to high temperature of being processed by the PPO/PPS plastic alloy is good, and dimensional stability is strong; Not yielding; Increased the insulator that is made up of aluminium foil between the inside and outside thermal expansion pipe, insulator and alloy skeleton are staggered evenly to be arranged between outer thermal expansion pipe and the interior thermal expansion pipe, can effectively play heat-blocking action.Loop configuration through different component coats and filling constitutes makes the performance of every kind of member on various structure, obtain good performance.Whole Sealing has been brought into play comprehensive sound-absorbing, sealing, reinforcement, heat-blocking action in actual application, all can play castering action preferably to the NVH performance and the Safety performance of car load.
