Abstract
The utility model belongs to the rubber dam technique field and discloses a rubber dam bag body. The technical proposal of the rubber dam bag body is as follows: the rubber dam bag body comprises a plurality of rubber sheets in a way of lapping and combining which comprise an external cover glue layer, an internal cover glue layer, at least two layers of skeleton layers and a middle rubber layer clamped between the skeleton layers. Lapping strips which are composed of the skeleton layers and the rubber layers are adhered to lapping crossbedding positions formed on two sides. The lapping strips adhered to the lapping crossbedding positions of the rubber dam bag body are composed of the skeleton layers and the rubber layers. The mechanical strength of the lapping strips is improved, the strength of the lapping crossbedding positions is improved, and the service life of the rubber dam bag body is prolonged. And the skeleton layers in the lapping strips can reduce the fluidness of the hot pressing process and overcome the happening of deviation phenomena, thereby improving the yield of products.
Description
Technical field
The utility model belongs to the part for rubber dam technical field, relates in particular to a kind of part for rubber dam bag.
Background technology
The part for rubber dam bag constitutes Bag Material by the some mesoglea that include outer covering glue layer, interior covering glue layer, two-layer at least casing play and be sandwiched between casing play, and bonding bonding jumper sealing forms by overlap joint and at overlap joint staggered floor position in its end.At present, employed bonding jumper is made for the gum material at overlap joint staggered floor position, and have a common boundary bar in hot pressing by what the gum material was made, because the flowability when high temperature is big, as easy as rolling off a log generation skew dislocation, make employed bonding jumper can not just in time be bonded in the overlap joint staggered floor place of rubber dam bag Bag Material end, thereby reduce the overall performance of part for rubber dam bag; The bonding jumper of gum material also exists easily aging and causes bonding layer place defective easy to crack in addition.
The utility model content
The purpose of this utility model just provides the part for rubber dam bag of good, anti-aging intensity height of a kind of overall performance and long service life.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of part for rubber dam bag, include outer covering glue layer, interior covering glue layer, two-layer at least casing play and be sandwiched in the sheet rubber overlap joint that the mesoglea between casing play constitutes by some and be bonded, overlap joint staggered floor place in two-sided formation is bonded with bonding jumper, and described bonding jumper is by one deck casing play and rubber layer constitute at least.
In addition, described casing play is served as reasons and is arranged warp and the sparse parallel formation cord fabric structure of arrangement closely.
Part for rubber dam bag provided by the utility model compared with prior art, have the following advantages: constitute by casing play and rubber layer owing to constitute the bonding bonding jumper in part for rubber dam bag overlap joint staggered floor position, improved the mechanical strength of bonding jumper, thereby make the intensity at overlap joint staggered floor place improve, prolonged the application life of part for rubber dam bag; Owing to contain the casing play structure in the bonding jumper, in the hot pressing process of this bonding jumper, reduced the flowability in the pressing, overcome the generation of shift phenomenon, thereby can improve the yield rate and the overall performance of product.
Description of drawings
The structural representation of the part for rubber dam bag that Fig. 1 provides for the utility model.
The specific embodiment
The structure of the part for rubber dam bag that the utility model is provided below in conjunction with accompanying drawing is described in further details.
As shown in Figure 1, be the structural representation of part for rubber dam bag.Being the rubber dam bag, overlap joint is bonding constitutes by sheet rubber 1,2, wherein sheet rubber includes outer covering glue layer 3 and interior covering glue layer 4, between this inside and outside covering glue layer, accompany and use first, second hole pattern skeleton 6,7 that the hole pattern that formed by the braiding of warp and parallel constitutes and be sandwiched in mesoglea 5 between skeleton, be bonded with the bonding jumper that the upper and lower rubber layer 9 and 10 of the casing play 8 that formed by cloth and both sides applying constitutes at the two-sided overlap joint staggered floor place that sheet rubber 1,2 overlap joints form.
In order to improve the tearing toughness of bonding jumper, warp constitutes the cord fabric structure with the sparse parallel of arrangement to employed skeleton by arranging closely, and the rubber layer that promptly fits in the cord fabric both sides can be into a single integrated structure by mesh shape.
In above-mentioned bonding jumper structure, casing play 8 can be provided with multilayer as required, and such as the two-layer cage construction that can be arranged to as sheet rubber, the intensity of the bonding jumper of formation can be higher.
Claims (2)
1, a kind of part for rubber dam bag, include outer covering glue layer, interior covering glue layer, two-layer at least casing play and be sandwiched in the sheet rubber overlap joint that the mesoglea between casing play constitutes by some and be bonded, overlap joint staggered floor place in two-sided formation is bonded with bonding jumper, it is characterized in that: the upper and lower rubber layer of fitting in casing play that described bonding jumper is formed by cloth and both sides constitutes.
2, a kind of part for rubber dam bag according to claim 1 is characterized in that: described casing play is served as reasons and is arranged warp and the sparse parallel formation cord fabric structure of arrangement closely.
