Problems solved by technology

[0003] At present, car sound insulation pads are mainly made of recycled fiber felt and PU foam material. However, due to the limitation of sound insulation material performance improvement technology, in order to obtain the expected sound insulation effect, it is often necessary to increase the thickness of the material itself. On the one hand, increase The material cost is reduced, on the other hand, it also takes up a lot of space inside the equipment, and the compactness is poor

Abstract

The invention discloses a preparation process of a flame-retardant sound-insulation rubber pad, and relates to the technical field of sound-insulation material processing. The flame-retardant sound-insulation rubber pad comprises a sound-insulation layer, a flame-retardant layer and a waterproof layer which are sequentially arranged from bottom to top; wherein the preparation process of the flame-retardant and sound-insulation rubber pad comprises the steps of preparation of the sound-insulation layer, steam pumping, heating drying, gluing, cold die forming, cutting, quality inspection, packaging, warehousing and the like. The invention further discloses a drying and gluing integrated machine for drying and gluing treatment. The rubber pad can hold a good sound insulation effect on the premise that the thickness is not increased, the rubber pad is fluffy through cooperation with the production process suitable for the rubber pad, that is, steam at certain steam pressure, temperature and time is pumped, heating, drying, gluing and die assembly forming under certain pressure are achieved through the drying and gluing all-in-one machine, and tehrefore, the rubber pad product has excellent sound insulation and shock absorption effects.

Description
