Abstract
The flexible high-resistance interlayer stack and preparation method thereof based on thermoplastic elastomer (TPE) that the invention discloses a kind of.The laminated body of invention is a kind of high flexibility being combined by structure sheaf, adhesive layer and thermoplastic elastomer thin film, high gas barrier overlapped material.The thermoplastic elastomer has high gas-obstructing character and high flexibility, effective blocking oxygen or air；Structure sheaf is nylon fabric or dacron fabric or polyurethane fiber fabric, provides composite material higher intensity, by adhesive layer that fabric is integrally welded with thermoplastic elastomer films.Laminated body moulding process of the invention is simple, can be using simple hot pressing or the good fit of roll-in layers and adhesive layer, adhesive layer and thermoplastic elastomer films.
Description
Technical field
The present invention relates to a kind of laminate material with flexibility and high gas-obstructing character.
Background technique
It is very widely used in modern industry to the barrier property of the gases such as oxygen or air, for example, the clothes that keeps out the wind, air bag
Or aerostat etc., in such applications, basic demand, which has, is answered compared with high-air-tightness, and also with other structures or material
It closes, but for many occasions, in addition to exigent barrier properties for gases, also the use characteristic proposition of material is asked, such as soft
Property, it is substantially at present thermoplastic with the high material of high gas-obstructing character, such as polyamide, polyester or polyvinyl alcohol, this
The thermoplastic advantage of a little barrier properties is can be with other layer of body material such as metal or plastics or fiber using hot pressing or rolling
Apply processing, simple process.But have a defect that modulus is higher, especially in fabric sealing layer material, the sealing material of preparation
Expect stiff, feel is poor.Rubber has excellent flexibility, however, rubber material has two big defects for sealing material: first
With the complex forming technology of other layer materials, need further to vulcanize and bond；Second is that barrier property is lower, if applied using latex
Mode is covered, the thickness of coat is shallower, and barrier properties for gases is lower.If increasing the thickness of rubber barrier layer, quality is caused to increase.
Dynamic vulcanization thermoplastic elastomer is a kind of solderable processability with plastics, and has the flexibility of rubber and return
The thermoplastic material of elasticity.
Summary of the invention
1. the purpose of the present invention
The object of the present invention is to provide a kind of soft and have laminated body compared with high gas-obstructing character, the laminated body has structure
Layer, adhesive layer and barrier layer composition.Wherein brombutyl/polyamide that barrier layer is prepared using Technology of Dynamic Vulcanized
Thermoplastic elastomer (TPE), 0.08 ~ 0.15mm of thickness；Structure of the invention layer is nylon fabric or the fibres such as polyester textile or polyurethane loomage
Tie up fabric；Adhesive layer of the invention is polyamide thermoplastic or the hot melt adhesive films such as polyurethane or polyester.The present invention another object is that
The method for preparing the laminated body is provided, structure sheaf, adhesive layer and barrier layer are laminated by hot press forming technology, molding is simple.
2. technical solution
The object of the invention can be achieved through the following technical solutions:
Laminated body of the present invention is mainly made of load-carrying construction layer, adhesive layer and thermoplastic elastomer (TPE) barrier layer, wherein heat
Thermoplastic elastic layer is brombutyl/polyamide dynamic vulcanization thermoplastic elastomer film.
Structure sheaf of the present invention is nylon fabric or the fabrics such as polyester textile or polyurethane loomage.
Barrier layer of the present invention is the brombutyl/polyamide thermoplastic prepared using Technology of Dynamic Vulcanized
Property elastomer.Brombutyl/thermoplastic polyamide elastomer is at a temperature of 210 DEG C ~ 230 DEG C, in double screw extruder
In, brombutyl is dispersed in polyamide continuous phase using dynamic vulcanization technology, elastomer particle is prepared,
Particle is processed into thermoplastic elastomer thin film, 0.06 ~ 0.2mm of film thickness with inflation film manufacturing machine again
Adhesive layer of the invention is polyamide thermoplastic or the hot melt adhesive films such as polyurethane or polyester.
The present invention also provides a kind of preparation methods of laminated body.It include: first by the load-carrying construction layer, hot melt adhesive layers
With barrier layer stackup.It again at 80 DEG C ~ 145 DEG C, according to set temperature and pressure, suppresses, the pressing time is 10 ~ 40s.
3. beneficial effect
(1) laminated body provided by the invention is the flexibility that there is the high barrier of polyamide film to have rubber again, and thick
It spends relatively thin.
(2) stacking preparation process provided by the invention is simple, high-efficient, directlys adopt Thermoplastic hot melt glue film, utilizes
The method of hot pressing suppress.
