The utility model hot pressing cushion pad, described surface layer respectively has a medial surface adjacent to described cushion and a lateral surface in contrast to this medial surface, produces a gross thickness between 4 ㎜ to 10 ㎜ between described lateral surface.
The utility model hot pressing cushion pad, the main body of described cushion is silicon rubber foam material.
The utility model hot pressing cushion pad, described surface layer is silicon rubber material.
The utility model hot pressing cushion pad, the staple length of described cushion is between 1 ㎜ to 6 ㎜.
The beneficial effects of the utility model are: this hot pressing cushion pad utilizes this reinforced textile layer to promote withstand voltage mechanical strength, utilize described cushion that elastic buffer can be made to be uniformly distributed, preferably heat biography uniformity can be produced, utilize described surface layer that pressure then can be made average, this hot pressing cushion pad entirety has preferably hot pressing processing characteristics, and can increase the service life.
Accompanying drawing explanation
Fig. 1 is a combination generalized section of the utility model hot pressing cushion pad embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
Consult Fig. 1, an embodiment of the utility model hot pressing cushion pad, comprise a reinforced textile layer 10, two cushion 20 and two surface layers 30.
This reinforced textile layer 10 is formed by several warp-wise yarns and several broadwise yarn weavings, and at least one of them adopts glass fibre for described warp-wise yarn and described broadwise yarn, and has a first surface 11 and a second surface 12 in contrast to this first surface 11.In the present embodiment, described warp-wise yarn and the described broadwise yarn of this reinforced textile layer 10 all adopt glass fibre.
Described cushion 20 is fixedly arranged on this first surface 11 and this second surface 12 respectively, and respectively there is the main body 21 of an employing rubber pange material and several mixed short fiber 22 being contained in this main body 21 inside, described main body 21 respectively has several air chamber 211 be evenly distributed.The length of described short fiber 22 is between 1 ㎜ to 6 ㎜, and material can be carbon fiber, glass fibre, aromatic polyamide fibre, polyester fiber etc.Main body 21 material of the present embodiment is silicon rubber foam material, and described cushion 20 make mode, in silicone rubber material, mix the blowing agent and appropriate short fiber 22 that contain weight portion 3%, above-mentioned constituent is after heating, pressurization, equally distributed described air chamber 211 can be produced in this main body 21 inside, and it is inner to make described short fiber 22 be evenly distributed on this main body 21, the volume frothing percentage of described cushion 20 can reach 50%.
The quality of rubber materials (the present embodiment employing silicon rubber) that described surface layer 30 adopts density to be greater than described cushion 20 extrudes to be made, the outside of described cushion 20 is fixedly arranged on respectively in contrast to this reinforced textile layer 10, and respectively there is a medial surface 31 adjacent to described cushion 20 and a lateral surface 32 in contrast to this medial surface 31, at least one of them is cloudy surface shape to described lateral surface 32.
The mode of making of this hot pressing cushion pad is divided into two benches, first paragraph is continuous extruding, roll the described cushion 20 not yet sulfuration and foaming, and utilize viscose to be sticked in respectively by described cushion 20 first surface 11 of this reinforced textile layer 10 and second surface 12 form the laminate of three layers, again with continous way drum vulcanizer or mould-fixed vulcanizer by above-mentioned laminate hot pressing, make described cushion 20 by the mutual anchor knot of the hole of this reinforced textile layer 10, described cushion 20 itself also can sulfuration (being cross-linked) and foaming produce several air chamber 211 be evenly distributed, and several short fiber 22 is mixed, and to be contained in this main body 21 inner.Second segment is the laminate described surface layer 30 being sticked in formation one five layers outside described cushion 20, again with continous way drum vulcanizer or mould-fixed vulcanizer by above-mentioned laminate hot pressing, after undergoing hot pressing, described surface layer 30 links with described cushion 20 also sulfuration again (being cross-linked), finally can be consolidated into this hot pressing cushion pad.
Again as shown in Figure 1, produce a gross thickness H between 4 ㎜ to 10 ㎜ between the described lateral surface 32 of this hot pressing cushion pad, and the thickness of described cushion 20 is about equal with described surface layer 30.
The structure of this hot pressing cushion pad is utilized to produce following effect:
One, utilize the main body 21 of described cushion 20 inside to produce equally distributed described air chamber 211, then make this hot pressing cushion pad have preferably elasticity distribution and comparatively uniform heat and pass coefficient.
Two, utilize described surface layer 30 to be arranged on outside described cushion 20, this hot pressing cushion pad can be made such as, by laminate (figure does not show, solar cell, printed circuit board (PCB)) institute's applied pressure comparatively average.
Three, utilize main body 21 inside of described cushion 20 mixed containing short fiber 22, and described short fiber 22 adopt the materials such as carbon fiber, glass fibre, aromatic polyamide fibre, polyester fiber, can promote compression strength.When this hot pressing cushion pad is pressed, can produce preferably compression strength, there is better withstand voltage mechanical strength, after release of pressure, rebound degree is high, and then can increase the service life.
Four, warp-wise yarn, the broadwise yarn employing glass fibre of this reinforced textile layer 10, and utilize this reinforced textile layer 10 to be located between described cushion 20, described surface layer 30 is arranged on again the outside of described cushion 20, can promote the structural strength of this hot pressing cushion pad entirety.
In sum, the structure of the utility model hot pressing cushion pad is utilized really can to reach the purpose of this utility model.
