Description
Technical field
The present invention relates to foaming air bag bodies, and field is made, and in particular to be a kind of surface skining foaming air bag body at
Type technique, have the characteristics that damping performance is good and utricule in gas retention times it is permanent.
Background technique
A kind of specific manifestation form of the air cushion as damping indsole field, is enlivened many years on the market, tradition
Air cushion be to use air as buffer layer to promote the comfortable effect of human body dress, but most of air cushion is often only in the market
The problems such as being the decorative effect for playing appearance, being easy to gas leakage due to it, practical damping effect is not good enough；In addition traditional air cushion base
This is all to have transparent plastics to constitute, and the structure of its own is relatively hard, also affects people to a certain extent and wears shoes
Real experiences effect.
In view of this, the applicant furthers investigate regarding to the issue above, there is this case generation then.
Summary of the invention
The main purpose of the present invention is to provide a kind of moulding process of surface skining foaming air bag body, use elastic hair
Side wall of the foam material as air bag, and also solve simultaneously and the easy gas leakage of air cushion exists in the prior art and can not play and subtract for a long time
The problem of shock stability.
In order to achieve the above objectives, solution of the invention is:
A kind of moulding process of surface skining foaming air bag body, wherein include the following steps:
1. molding plastic capsules, the plastic capsules have side wall and the air bag in side wall；
It is impregnated 2. plastic capsules are put into high-pressure fluid, infiltrates into high-pressure fluid in the side wall of plastic capsules, through rising
Make the side wall high pressure fluid release of plastic capsules carry out foaming with the side wall to plastic capsules after temperature to handle to obtain foaming air bag
Body, the temperature after the heating reach 100-160 DEG C；
3. at 80-140 DEG C, under conditions of pressure 10MPa-20MPa, to foaming air bag body be inflated, allow foaming air bag
Body sticks out；
4. the foaming air bag body on surface forms fine and close skinning cortex after contacting with atmosphere quickly after die sinking.
Further, the step 2. in high-pressure fluid be nitrogen, the pressure of nitrogen is 15MPa-60MPa, temperature 80-
140℃；3. gas that the step is filled is carbon dioxide.
Further, the material that the plastic capsules use is TPU, PP, PE, TPEE, PET, EVA, PEBAX, PBT or PA
One of.
Further, 1. the step uses blow molding process to form and obtains plastic capsules after sealing.
After adopting the above structure, the present invention relates to a kind of moulding process of surface skining foaming air bag body, at least have
It is following the utility model has the advantages that
One, the present invention first molds plastic capsules, then carries out supercritical foaming processing to plastic capsules again to form hair
Air bag body is steeped, so that the side wall of entire air cushion all has high resiliency, the dress for not only considerably increasing it as sole is relaxed
Appropriateness, and it is also greatly reduced the quality of entire product, allow entire sole to seem lighter.
Two, the step of passing through the step of inflating again and quickly die sinking of the invention, first make inside foaming air bag body
Gas can be more sufficient, second by quickly die sinking cooling, the outer surface of entire foaming air bag body is allowed to form one layer of densification
Skinning cortex, this skinning cortex is for stopping gas in air bag exposed, to greatly prolong the service life of entire foaming air bag body.
Three, the present invention utilizes the opportunity of the non-skinning in outer surface in the air bag body that foams rigid foaming, using penetrability pole
Strong carbon dioxide has been inflated to be inflated to foaming air bag body and has just carried out quickly being opened cooling skinning later, so that it is guaranteed that
Tolerance recombination in air bag body substantially increases the integrated quality of entire foaming air bag body.
Detailed description of the invention
Fig. 1 is that the present invention relates to a kind of flow charts of the moulding process of surface skining foaming air bag body.
Fig. 2 is that a kind of foaming air bag body of the present invention applies the structural schematic diagram in midsole.
In figure:
Foam air bag body -1.
Specific embodiment
In order to further explain the technical solution of the present invention, being explained in detail below by specific embodiment the present invention
It states.
As shown in Figure 1, including the following steps: the present invention relates to a kind of moulding process of surface skining foaming air bag body
1. molding plastic capsules, the plastic capsules have side wall and the air bag in side wall；As a kind of excellent
Embodiment is selected, 1. the step uses blow molding process to form and obtains plastic capsules after sealing, naturally it is also possible to use other
Technique is made plastic capsules, is not specifically limited again.
It is impregnated 2. plastic capsules are put into high-pressure fluid, infiltrates into high-pressure fluid in the side wall of plastic capsules, through rising
Make the side wall high pressure fluid release of plastic capsules carry out foaming with the side wall to plastic capsules after temperature to handle to obtain foaming air bag
Body, the temperature after the heating reach 100-160 DEG C；Preferably, the step 2. in high-pressure fluid be nitrogen, the pressure of nitrogen
Power is 15MPa-60MPa, and temperature is 80-140 DEG C；
3. at 80-140 DEG C, under conditions of pressure 10MPa-20MPa, to foaming air bag body be inflated, allow foaming air bag
Body sticks out；Preferably, the gas that 3. is step is filled carbon dioxide, and take full advantage of carbon dioxide gas penetrates energy
Power；
4. the foaming air bag body on surface forms fine and close skinning cortex after contacting with atmosphere quickly after die sinking.
In this way, at least having following beneficial to effect the present invention relates to a kind of moulding process of surface skining foaming air bag body
Fruit:
One, the present invention first molds plastic capsules, then carries out supercritical foaming processing to plastic capsules again to form hair
Air bag body is steeped, so that the side wall of entire air cushion all has high resiliency, the dress for not only considerably increasing it as sole is relaxed
