Problems solved by technology

Due to the poor flatness of the surface of the dam bag, it is necessary to add a flat sheet at the part where the two dam bags are connected to each other. Since the flat sheet is made of rubber material, it has high fluidity during high temperature hot pressing and is easy to Offset and dislocation occur, so that the used flat sheet cannot be

Example Embodiment

[0026] Example 1

[0027] A rubber dam bag and its processing technology reference attachment figure 2 A rubber dam bag includes a dam body 1 connected in sequence. Two adjacent dam bodies 1 are connected by an unvulcanized soft section 4. The dam body 1 and the soft section 4 are an integral structure. The number of bodies 1 is equal to 2, and the soft section 4 is rubber soft.

[0028] The processing technology of the rubber dam bag of this embodiment includes the following processing steps:

[0029] 1. Fold

[0030] Measure a length of the starting end of the dam bag and place it outside the width of the single-width vulcanizer, and then lay the dam body 1 of the dam bag on the surface of the single-width vulcanizer with the width of the single-width vulcanizer, and fold it upward once to form a fold The mezzanine, the folding route is S-shaped.

[0031] 2. Isolation

[0032] Lay a non-woven fabric layer 2 containing a release agent with a size matching the area of ​​the folding s...

[0038] Example 2

[0039] Reference Attachment for a rubber dam bag and its production method of this embodiment figure 2 The difference from Embodiment 1 is that the number of dams 1 is five.

[0040] The method for producing a rubber dam bag in this embodiment includes the following processing steps:

[0041] 1. Fold

[0042] Measure a length of the starting end of the dam bag and place it outside the width of the single-width vulcanizer, and then lay the dam body 1 of the dam bag on the surface of the single-width vulcanizer with the width of the single-width vulcanizer, and fold upwards in turn to form a folded interlayer. Fold up 4 times, the folding route takes a 2-shape.

[0043] 2. Isolation

[0044] Lay a non-woven fabric layer 2 containing a release agent with a size matching the area of ​​the folding surface in the folded interlayer so that the adjacent folding surfaces will not stick during vulcanization.

[0051] Reference attachment of a rubber dam bag and its production method in this embodiment figure 2 , The difference from Embodiment 1 is that the number of dams 1 is 10.

[0052] The method for producing a rubber dam bag in this embodiment includes the following processing steps:

[0053] 1. Fold

[0054] Measure a length of the starting end of the dam bag and place it outside the width of the single-width vulcanizer, and then lay the dam body 1 of the dam bag on the surface of the single-width vulcanizer with the width of the single-width vulcanizer, and fold upwards in turn to form a folded interlayer. Fold upward 9 times, the folding route is S-shaped.

[0055] 2. Isolation

[0056] Lay a non-woven fabric layer 2 containing a release agent with a size matching the area of ​​the folded surface in the folded interlayer so that adjacent folded surfaces will not stick during vulcanization.

Abstract

The invention relates to a dam bag of a rubber dam and a processing technology thereof, belonging to the technical fields of dam bags of the rubber dam and a production method thereof. The dam bag of the rubber dam comprises successively-connected dam bodies, a unvulcanized rheid section is used for connecting adjacent dam bodies, the dam bodies and the rheid sections are in an integral structure, the number of the dam bodies 1 is more than or equal to 2, ranging from 2 to 10, and the rheid section 4 is a rubber rheid. The processing technology comprises the following steps: 1) folding; 2) separating; 3) vulcanizing and shaping at one time; and 4) flattening. As for the dam bag of the rubber dam and the production method thereof provided by the invention, the dam is long in service life, convenient in processing and high in safety coefficient, and the breadth of the dam bag is as much as 10m.

Description

technical field [0001] The invention relates to a rubber dam bag and a processing technology thereof, and belongs to the technical field of rubber dam bags and production methods thereof. Background technique [0002] At present, when producing rubber dam bags, single-width vulcanization with a flat vulcanizer is generally used, and the width of the dam bags produced is only less than 1.1 meters. Due to the short width and length, several dam bags need to be connected to each other in actual use Tower joints are used to increase the width, so there is a tower joint within less than one meter along the length of the dam. Due to the poor flatness of the surface of the dam bag, it is necessary to add a flat sheet at the part where the two dam bags are connected to each other. Since the flat sheet is made of rubber material, it has high fluidity during high temperature hot pressing and is easy to Offset and dislocation occur, so that the used flat sheet cannot be glued to the s...
