Embodiment 1

[0018] Embodiment one: refer to figure 1 , the production process of the rubber lateral stopper is carried out according to the following steps:

[0019] A: Select a 100T plate vulcanizing machine, set the temperature of the upper plate to 175°C, and set the temperature of the lower plate to 165°C. Then the production mold is placed on the flat vulcanizer, the pressure of the flat vulcanizer is set to 18MPa, and it is guaranteed that the mold is preheated for 3 hours.

[0020] B: The bottom plate of the rubber stop is put into the steel shot blasting machine for 15 minutes; the hard stop is put into the quartz sand blasting machine for 12 minutes.

[0021] C: Use the glue protection tool to protect the bottom plate and hard stop processed in the B process, and then paint the primer and surface glue. The coating thickness of primer is 18μm, the drying temperature is 70℃, and the drying time is 30min. The coating thickness of the surface adhesive is 60 μm, the drying temperat...

Abstract

The invention discloses a high-temperature short vulcanization process for a transverse rubber backstop, relating to an improvement on the conventional vulcanization process for the transverse backstop. The transverse backstop is produced according to the following steps and process parameters: A, setting the plate temperature of a vulcanizing press to ensure that the temperature of a mold cavity in a mould is 100-170 DEG C; B, recycling a rubber material to enable the rubber material to be rolled to be round after being recycled so as to be conveniently placed into a rubber injection cylinder; C, setting the pressure of the vulcanizing press to ensure that the pressure inside the mould is 5-15MPa; D, setting the vulcanizing time to be 10-15minutes; E, placing a lower bottom plate of the backstop into a steel shot sand blasting machine to blast shots for 8-20minutes, and placing a hard backstop into a quartz sand blasting machine to blast sand for 10-30minutes; and F, placing the formed rubber material into the rubber injection cylinder of the mould to pressurize and vulcanize. The high-temperature short vulcanization process can be used for forming the transverse rubber backstop through high-temperature short vulcanization and ensuring that a product with the rubber layer thickness of 20-50mm is vulcanized to be matured. By using the high-temperature short vulcanization process, the vertical rigidity of the product can meet the requirement of an index when the product is compressed to 10-22mm under the condition of a vertical loading force.

Description

technical field [0001] The invention discloses a novel rubber transverse stop vulcanization process, which relates to the improvement of the existing production process of the rubber transverse stop. Background technique [0002] At present, the production of rubber lateral stoppers takes a long time to vulcanize, and the production efficiency is low. Moreover, when the product is in the working state, the vertical stiffness curve rises rapidly, resulting in a compression of 10mm~22mm, the vertical stiffness cannot meet the index requirements, which seriously affects the product. Play the role of stop gear. Therefore, the existing processing technology has the problems of poor comprehensive performance such as long time consumption and substandard performance. Contents of the invention [0003] The purpose of the present invention is to provide a production process for rubber transverse stops. The present invention solves the problems of substandard product performance, l...
