Silicon rubber sealing strip low-temperature bonding device and process method

Abstract

The invention provides a silicon rubber sealing strip low-temperature bonding device and a process method. The silicon rubber sealing strip low-temperature bonding device comprise a PC base plate anda PC cover plate, wherein a first cavity strip frame is arranged on the top surface of the PC base plate, a plurality of stainless steel screws are arranged in the middle of the top surface of the PCbase plate, a second cavity strip frame is arranged on the bottom surface of the PC cover plate, a plurality of positioning through holes corresponding to the stainless steel screws are formed in themiddle of the PC cover plate, and the stainless steel screws penetrate through the positioning through hole and are connected with stainless steel nuts. The process method comprises the following steps of inspection; placement; re-inspection; cold bonding; and taking out. An oven is adopted to carry out 70 DEG C low-temperature bonding treatment, the bonding time can be reduced, and sealing stripscannot be deformed. A special low-temperature bonding device is designed, and the silicon rubber sealing strips can be conveniently placed and transferred. The PC plates and single-component liquid silica gel are adopted and are not bonded with each other. The first cavity strip frame and the second cavity strip frame are designed into full-size outlines, the product size can be verified, and thelater inspection process is saved.

Description

【Technical field】 [0001] The invention relates to the technical field of silicone rubber product processing, in particular to a low-temperature bonding device and process method for silicone rubber sealing strips. 【Background technique】 [0002] Silicone rubber sealing strip has excellent high temperature resistance and low temperature resistance, good physiological stability, excellent small back deformation, ozone resistance and ultraviolet resistance, and is widely used in medical diversion, electronics, lighter tubes, and ignition guns Pipes, wires and cables... processed into sealing strips and flange rings have good performance in drying equipment, especially on the door of drying machines, which are more than three times the service life of ordinary rubber seals. [0003] In the prior art, high-temperature bonding or low-temperature bonding is used for the bonding of silicone rubber sealing strips. The high-temperature bonding method easily deforms the silicone rubber...
