Embodiment 1

[0022] This embodiment provides a sponge pad, comprising two sandwich layers, a central layer arranged between the two sandwich layers, and an outer layer arranged on the surfaces of the two sandwich layers, and the sandwich layer is fixedly connected to the central layer , the outer layer is fixedly connected with the sandwich layer. The material of the sandwich layer is an elastic material, and the elastic material includes sponge, but is not limited thereto. Preferably, the material of the central layer includes high-density polyester cloth, and the material of the outer layer includes knitted polyester cloth.

[0023] Further, a method for preparing a sponge pad is provided, which includes setting a central layer in the middle of the sandwich layer, setting outer layers on both sides of the sandwich layer, and combining the center layer, the sandwich layer and the outer layer through flame compounding.

[0024] Further, the application of the sponge cloth in the productio...

Abstract

The invention discloses a sponge laying cloth and a preparation method and applications thereof. The sponge laying cloth comprises two sandwich layers; a middle layer, which is arranged between the sandwich layers; and two external layers, which are arranged on the surfaces of two sandwich layers. The sandwich layers are fixedly connected to the middle layer. The external layers are fixedly connected to the sandwich layers. By setting two sandwich layers, the middle layer arranged between two sandwich layers, and external layers arranged on the surfaces of two sandwich layers, solved are the problems that in tire production, the force applied on a tire is not uniform, and the fresh keeping performance is bad. The middle layer is made of high density polyurethane cloth, the stiffness is largely improved, during the rolling process, the force on a sheet is uniform, and deformation is maximally avoided. The sandwich layers are made of sponge, the external layers are made of woven polyester fabrics, through the cooperation between the sandwich layers and the external layers, the fresh keeping performance and the wet absorbing performance are good; the sponge laying cloth has dual protection functions, and the peeling of layers due to long term contact with a rubber sheet is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of tire manufacturing, in particular to a sponge pad and its preparation method and application. Background technique [0002] With the rise and vigorous development of the automobile industry, people have higher and higher requirements for the quality of rubber tires. During the tire manufacturing process, pads are often used to separate the rubber compound placed in rolls. However, due to the heavy weight of the rubber, there is a high requirement for the performance of the pad. Only when the performance of the pad is high, can rubber products such as carcass be prevented from being deformed when placed in rolls. When tire factories initially produced tires, they used snakeskin bags to separate and curl the rubber. However, during the curling, the film is unevenly stressed, and the freshness preservation performance is poor, which greatly affects the quality of the rubber, resul...
