Abstract
The invention relates to a non-pressure heat vulcanization bonding type high-performance rubber damping fin material which is simple and feasible and low in cost, can be industrially reproduced and can be stuck on a metal surface of a vehicle body through non-pressure heat vulcanization. The non-pressure heat vulcanization bonding type high-performance rubber damping fin material mainly takes a butyl rubber and maleic anhydride grafted ethylene-vinyl acetate copolymer (EVA) commixing system as a matrix, inorganic filling as a main filling reinforcing agent, epoxy resin as a tackifier and sulfur as a vulcanization system; the problems of high damping and high temperature range of a rubber damping fin and a non-pressure heat vulcanization bonding process and the like in a process of mounting the damping fin are solved. In a preparation process, the butyl rubber, the maleic anhydride grafted EVA and the like are added into an internal mixer at 100 DEG C to 130 DEG C, and are mixed to be sufficiently dispersed into the polymer matrix; then the epoxy resin and the vulcanization system on an open mill are added into rubber master batch and are mixed to form mixed rubber; the mixed rubber is molded into a damping rubber plate by adopting a high-pressure extruder; then the damping rubber plate is cut into a rubber damping fin with a qualified size according to a design shape of an automobile damping plate.
Description
technical field [0001] The invention relates to a pressureless hot vulcanization adhesive high-performance rubber damping sheet material which is simple, easy to operate, low in cost, can be reproduced industrially and can be pasted on the metal surface of a vehicle body without pressure hot vulcanization, and belongs to the field of rubber damping sheet material manufacturing. . Background technique [0002] The damping film is pasted on the surface of the vibrating parts, which can effectively reduce the mechanical noise and reduce the mechanical vibration and resonance. It is widely used in various mechanical equipment, especially in 8 to 12 parts such as the front panel, door, roof, floor, trunk, etc. 2 , the weight is about 8 to 15 kilograms, and the market economic benefit scale exceeds 10 billion yuan. [0003] Traditional hot-melt damping materials use asphalt as the main base material and are supplemented by damping pads made of inorganic fillers. It is well know...
