Abstract

The invention provides a spot welding sealing foaming rubber pad for a vehicle and belongs to the technical field of vehicle spot welding. The spot welding sealing foaming rubber pad is prepared fromthe following raw materials in parts by weight: butyl rubber 20-30%; 10-20% of paraffin oil; 3-5% of hydrogenated C5 petroleum resin; 5-10% of conductive carbon black; 10-20% of a flame retardant; 10-30% of mica powder; 10-30% of vermiculite powder; 1-2% of zinc oxide; 0.5-1% of stearic acid; 0.5-1% of sulfur; 1.0-3.0% of a crosslinking aid; 1-3% of a foaming agent; and 1-1.8% of an anti-aging agent. The preparation method of the product is simple; the mica powder and vermiculite powder are added, so that noise reduction and shock absorption functions are increased; the prepared rubber pad product can be foamed at high temperature; in the process that an automobile passes through a coating workshop, the foaming filling of the rubber pad in a metal plate can be synchronously achieved on a coating line, and the effects of damping, noise reduction, sound insulation and flame retardance are achieved. The rubber pad can be widely applied to the filling and sealing of gaps of the automobilemetal plate without avoiding welding spots.
