Description
Technical field
The utility model is related to a kind of release paper fields, and in particular to a kind of high ventilative release paper.
Background technology
Release paper is also known as barrier paper, separate paper, silicone oil paper.Being one kind preventing prepreg adhesion, and can protect prepreg
Not contaminated separate paper.Release paper is made of the paper for being coated with preventing viscosity substance, and model will be according to material, thickness, elongation, list
Two-sided difference and distinguish.
Release paper gas permeability on the market is bad at present, is unable to meet production the needs with life, and some are to carry
The gas permeability of high release paper and the intensity for reducing release paper.
Invention content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high ventilative release paper, Neng Gou
While ensureing gas permeability, and intensity is also ensured.
In order to realize above-mentioned target, the utility model adopts the following technical scheme：
A kind of high ventilative release paper, including bottom, leaching membrane layer and silicon layer, the leaching membrane layer are located at bottom and silicon layer
Centre, and side is connected with bottom, and the other side is connected with silicon layer, and the bottom, leaching membrane layer and silicon layer are equipped with logical
Hole, the through-hole include the first hole body, the second hole body and third hole body, and are N font structures, first hole body and the
It is parallel between three hole bodies, and mutually stagger, the both ends of second hole body are connected with the first hole body, third hole body respectively, institute
The cross section for stating through-hole is regular hexagon structure or octagon structure, is additionally provided on the bottom, leaching membrane layer and silicon layer
Symmetrical holes, using the vertical line of bottom as axis axisymmetricly structure between the symmetrical holes and through-hole, and symmetrical holes with through-hole not
It contacts with each other, the through-hole collectively constitutes air hole group with symmetrical holes.
Further, bottom, leaching membrane layer and silicon layer are equipped with several air hole groups, and between each air hole group
Distance be equal.
Further, the angle between the second hole body and the first hole body is 90 °.
Further, the angle between the second hole body and the first hole body is 30 ° ~ 60 °.
Further, the cross-sectional area of the first hole body be more than third hole body cross-sectional area, the third hole body it is transversal
Area is more than the cross-sectional area of the second hole body.
The utility model is beneficial in that：
The utility model passes through the design to air hole group so that the gas permeability of release paper greatly improves, and air hole
The shape of group can ensure that intensity is constant when paper is pullled, and N font structures generate subtle when enabling to be pullled
Elastic deformation, to ensure that sheet is not easily damaged, and when receiving extruding, N character form structures also can guarantee that internal there are certain skies
Gas and the deformation for preventing sheet excessive, to proof strength.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
The meaning of reference numeral in figure：
1 it is bottom, 2 be leaching membrane layer, 3 be silicon layer, 4 be through-hole, 5 be the first hole body, 6 be the second hole body, 7 is third hole
Body, 8 are the second hole body.
Specific implementation mode
The utility model is further described and is illustrated with reference to embodiment and attached drawing, but is not limited in any form
The system present invention.
As shown in Figure 1, a kind of high ventilative release paper, including bottom, leaching membrane layer and silicon layer, the leaching membrane layer are located at bottom
Among layer and silicon layer, and side is connected with bottom, and the other side is connected with silicon layer, the bottom, leaching membrane layer and silicone oil
Layer is equipped with through-hole, and the through-hole includes the first hole body, the second hole body and third hole body, and is N font structures, and described the
It is parallel between one hole body and third hole body, and mutually stagger, the both ends of second hole body respectively with the first hole body, third hole
Body is connected, and the cross section of the through-hole is regular hexagon structure or octagon structure, the bottom, leaching membrane layer and silicon layer
On be additionally provided with symmetrical holes, using the vertical line of bottom as axis axisymmetricly structure, and symmetrical holes between the symmetrical holes and through-hole
It does not contact with each other with through-hole, the through-hole collectively constitutes air hole group with symmetrical holes.
Wherein, several air hole groups can be equipped on bottom, leaching membrane layer and silicon layer, and between each air hole group
Distance be equal, the increase of multiple air hole groups can improve the gas permeability of release paper so that air permeability effect is more obvious.
Angle between second hole body and the first hole body can be 90 °, and 90 ° of angle enables to air permeability effect brighter
It is aobvious, and the reduction of intensity is made to influence to minimize.
Angle between second hole body and the first hole body can be 30 °, and 30 ° of angle can be while not losing gas permeability
The maximum elastic deformation for meeting release paper, the intensity of release paper is improved with this.
Another embodiment of the utility model, and above-mentioned difference lies in the folders between the second hole body and the first hole body
Angle is 45 °.
Another embodiment of the utility model, and above-mentioned difference lies in the folders between the second hole body and the first hole body
Angle is 60 °.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
The technical solution obtained, all falls in the scope of protection of the utility model.
