Sandwich type under-plate elastic backing plate and preparation process thereof
The invention provides a sandwich type under-plate elastic backing plate and a preparation process thereof, the sandwich type under-plate elastic backing plate comprises upper layer rubber, lower layer rubber and a middle micropore elastic layer, the upper layer rubber is provided with an upper layer groove, the lower layer rubber is provided with a lower layer groove, the middle micropore elastic layer is located between the upper layer rubber and the lower layer rubber, and the layers are connected in a bonding mode. The bonding strength of the cushion plate needs to be guaranteed to exceed the tensile strength of the cushion plate material, during bonding, the upper-layer grooves face upwards, the lower-layer grooves face downwards, and the middle microporous elastic layer is made of fully-foamed polyurethane or rubber materials, is of a microporous structure and is low in density. According to the invention, the rigidity of the base plate is reduced while the material consumption is reduced, and the vibration damping performance of the fastener is improved.
本发明提供一种夹心式板下弹性垫板及其制备工艺，包括上层橡胶、下层橡胶、中间微孔弹性层，上层橡胶开有上层沟槽，下层橡胶开有下层沟槽，所述中间微孔弹性层位于上层橡胶和下层橡胶之间，层间进行粘接连接，并需保证其粘接强度超过垫板材料的拉伸强度，粘接时，上层沟槽朝上，下层沟槽朝下，中间微孔弹性层采用充分发泡聚氨酯或橡胶材料，为微孔结构，密度低。本发明在减少用料的同时，降低了垫板的刚度，提升了扣件的减振性能。
