Example Embodiment

[0018] Example 1: Reference figure 1 , The production process of rubber lateral stop is carried out according to the following steps:

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

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

[0021] C: Protect the bottom plate and hard stop that has been processed in the B process with a glue protection tool, and then apply the primer and surface glue. The primer coating thickness is 18μm, the drying temperature is 70°C, and the drying time is 30min. The coating thickness of the top glue is 60μm, the drying temperature is 85℃, and the drying ti...

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...
