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 ...

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.

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 surface in the folded interlayer so that the adjacent folding surfaces will not stick during vulcanization.

[0033] 3. One-time vulcanization molding

[0034] The double layer after folding and isolation is simultaneously formed and vulcanized by a flat vulcanizer. The soft section 4 at the corner where adjacent layers meet is not vulcanized, and the remaining two vulcanized layers form two dams 1 .

[0035] 4. Flatten

[0036] The dam bag after forming and vulcanization is taken out of the flat vulcanizer. Since the soft section 4 at the corner is not vulcanized, each corner is used as the axis and each layer is stretched sequentially to form a rubber dam bag.

[0037] The release agent is emulsified silicone rubber.

Example Embodiment

[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.

[0045] 3. One-time vulcanization molding

[0046] The five layers after folding and isolation are simultaneously formed and vulcanized by a flat vulcanizer. The soft section 4 at the corner where adjacent layers meet is not vulcanized, while the remaining five vulcanized layers form five dams 1 .

[0047] 4. Flatten

[0048] Take out the dam bag after forming and vulcanization from the flat vulcanizer. Since the soft section 4 at the corner of each layer is not vulcanized, each layer is stretched out in turn with each corner as the axis to form a rubber dam bag .

[0049] The release agent is emulsified silicone rubber.

Example Embodiment

[0050] Example 3

[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.

[0057] 3. One-time vulcanization molding

[0058] The 10 layers after folding and isolation are simultaneously formed and vulcanized by a flat vulcanizer. The soft section 4 at the corner where adjacent layers meet is not vulcanized, and the remaining 10 vulcanized layers form 10 dams 1 .

[0059] 4. Flatten

[0060] Take out the dam bag after forming and vulcanization from the flat vulcanizer. Since the soft section 4 at the corner of each layer is not vulcanized, each layer is stretched out in turn with each corner as the axis to form a rubber dam bag .

[0061] The release agent is emulsified silicon standard glue.

[0062] The above embodiments have the following positive effects:

[0063] 1) The double-layer or multi-layer dam body is simultaneously formed and vulcanized to realize the increase of the single width of the dam bag. The overall seam of the dam bag is reduced by 70%-75%, and the appearance quality of the dam bag is improved, and the safety factor of the dam bag is also improved.

[0064] 2). Since the single width of the dam bag can reach 10 meters, rubber dams with a dam height of less than 2 meters can be made into non-overlap dam bags.

[0065] 3). Due to the simultaneous molding and vulcanization process of double or multi-layer dam bags, the production efficiency of molding and vulcanization is increased by 1.6 times.
