Description
Technical field
The utility model is related to double faced adhesive tape technical field, specially a kind of novel no base material double faced adhesive tape.
Background technology
No base material double faced adhesive tape is exactly that glue is not coated on above any base material, a kind of glue being coated directly onto in release paper
Band has excellent water resistance, and processability is good, temperature tolerance is good, and dimensional stability, thermal stability, chemical stability are good, just viscous
Property and hold viscosity it is good the features such as, by electronics industry extensive use, since the capacity of heat transmission of existing no base material double faced adhesive tape is bad, lead
Cause electronic product heat radiation energy force difference, the lost of life, meanwhile, existing adhesive tape is used primarily in electronic component, electronic component
Often being in the working condition of high temperature can cause electronic component excessively high because of local heating when the heat dissipation performance of adhesive tape is bad
And fail, damage, and adhesive tape in the prior art often only serves sealing and fixed function, not only cannot heat conduction well, also
Because its thermal insulation is more unfavorable for radiating, simultaneously because the heat generated in the electronic product course of work, for a long time to colloid
It is heated so that colloid heated denaturalization influences its normally viscous stickiness.
Invention content
In order to overcome the shortcomings of that prior art, the utility model provide a kind of novel no base material double faced adhesive tape, realize
Good viscous gluing contacting surface, the adaptive expanded with heat and contract with cold, more preferably heat conduction and heat radiation.
Technical solution adopted by the utility model to solve its technical problems is：A kind of novel no base material double faced adhesive tape, packet
Acrylic glue, fibrous layer, silica gel composite layer are included, the fibrous layer is arranged between silica gel composite layer and acrylic glue, the silicon
Glue composite layer is coated with envelope crystal layer, and the silica gel composite layer is internally provided with sodium bicarbonate particle, and the silica gel is compound
It is provided with side among the both sides of layer and connects inseam.
As a kind of technical solution having choosing of the utility model, acrylic glue surface is attached with release film.
As a kind of technical solution having choosing of the utility model, acrylic glue surface is in cancave cambered surface.
As a kind of technical solution having choosing of the utility model, the fibrous layer uses Modified Activated Carbon fibrous material, and described
Fibrous layer and silica gel composite layer weave in, and pass through envelope crystal layer.
As a kind of technical solution having choosing of the utility model, the silica gel composite layer upper and lower surface is in concave arc planar.
Compared with prior art, the utility model has the beneficial effects that：
1）In structure, the acrylic glue of the cancave cambered surface of the utility model realizes that the elasticity of contact surface glues stickiness, matches simultaneously
Cambered surface of dashing forward in closing keeps the ability of its double faced adhesive tape deformation, the intertexture guarantee of silica gel composite layer and fibrous layer when realizing that strength is viscous glutinous
The integral strength of double faced adhesive tape connects seam in the side of silica gel composite layer both sides and provides and adaptability of the double faced adhesive tape in deformation；
2）In thermal conductivity, the heat of sticky surface is carried out quickly by internal silica gel composite layer and sodium bicarbonate particle
Heat is transmitted, and when being transferred to envelope crystal layer, by the one-way of crystal heat conduction, is radiated to double faced adhesive tape both sides, avoiding will be excessive
Heat transfer to another sticky surface acrylic glue, reduce acrylic glue long-time heated denaturalization.
