Abstract
The utility model discloses a pressure-bearing leakage stoppage glue stick. The pressure-bearing leakage stoppage glue stick is composed of an elastic body and a soft surface layer, wherein the elastic body is made of imported graphite and fiber polymer nanomaterials in mixing mode, and the fiber polymer nanomaterials are made by DuPont in the United States. The soft surface layer is mounted on the surface of the elastic body in bonding mode through an adhesive, and the soft surface layer is made of ethylene-vinyl acetate (EVA). The pressure-bearing leakage stoppage glue stick can withstand high temperatures, can be used to seal any medium, and has great anti-corrosion and sealing effect.
Description
Technical field
The utility model belongs to a kind of sealing material, relates in particular to a kind of sealing glue stick that is made of composite material.
Background technique
Existing sealing glue stick can only bear more than 400 the medium of degree, and the sealing glue stick media-resistant that this material is made is limited, and it is deposited, and long-lasting aspect of construction and anti-corrosion protection is aobvious to spill obvious deficiency.At present, domestic the viscoelastic body product has been launched research.Yet viscoelastic body glue is as anticorrosive coat, its shear strength is less, and it is relatively poor to resist extraneous mechanical forces, especially under the environment of some high temperature, common viscoelastic body dope product can be because of the reason of extraneous mechanical force but anticorrosive coat to heavy damage, affect the corrosion proof and leakproof effect.
Summary of the invention
The utility model is according to defective of the prior art, provides a kind of heatproof degree high, and any medium can seal and the pressure leakage-stopping glue rod of preserving and sealing better effects if.
Pressure leakage-stopping glue rod of the present utility model is comprised of elastomer and soft top layer.Wherein elastomer is that import graphite and Dupont fiber polymer nanometer material mix, and utilizes the bonding soft top layer of adhesive on elastomeric surface, and wherein soft top layer is EVA.
Preferably, pressure leakage-stopping glue rod temperature applicable range is-195 ℃-800 ℃.
The utility model compared with prior art has the following advantages: owing to utilize preferably elastic material and sticking and its surperficial top layer to make the pressure leakage-stopping glue rod, compare with original rubber seal glue rod, good seal performance, corrosion proof and leakproof is effective, can also be suitable for any chemical mediator.
Description of drawings
The structural representation of Fig. 1 the utility model pressure leakage-stopping glue rod.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model pressure leakage-stopping glue rod is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, pressure leakage-stopping glue rod of the present utility model is comprised of elastomer 1 and soft top layer 2.Wherein elastomer 1 is for import graphite and Dupont fiber polymer nanometer material mix, and elastomer 1 plays sealing and buffering;
Utilize the bonding soft top layer 2 of adhesive on elastomeric surface, top layer 2 is used for sealing and the high-temperature capability that improves whole sealing glue stick, and wherein soft top layer is EVA.
More than described preferred embodiment of the present utility model, but it will be understood by those skilled in the art that under the prerequisite that does not break away from the utility model design philosophy, its various modification or combination are all included in the protection domain of claim of the present utility model.
