AI Technical Summary
Technical Problem
[0003]现有膨胀密封胶块在车身空腔发泡后很难100％密封所在空腔，存在漏水风险，同时，现有膨胀密封胶块结构为一层骨架加一道发泡胶密封，当仅有的一道发泡胶发泡后存在孔洞时，此截面没有其他措施继续封堵，将会导致密封失效，密封效果差，因此，本发明提出一种用于车辆空腔水密封缝的膨胀密封胶块结构以解决现有技术中存在的问题
Benefits of technology
[0014] The beneficial effects of this invention are as follows: This invention uses two sets of high-density foamed adhesive blocks, combined with hot-flowing molten adhesive blocks, to foam and fill the gaps in the body sheet metal, achieving 100% sealing and filling, which greatly improves the sealing performance of the body cavity and enhances the water tightness of the body. At the same time, the specially made high-density foamed adhesive blocks and hot-flowing molten adhesive blocks effectively enhance the strength and flame retardant properties of the sealant.
