Abstract
The invention relates to a pressure-sensitive adhesive and a pressure-sensitive adhesive tape, and a preparation method thereof. The pressure-sensitive adhesive provided by the invention comprises natural rubber, styrene-butadiene rubber, nitrile-butadiene rubber, acrylate rubber, terpene resin, C5 resin, phenol formaldehyde resin and isocyanate. The preparation method comprises the following steps: after mixing and plasticizing the four rubbers, dissolving in an organic solvent, adding the other components, and stirring for 20-30 hours to obtain the pressure-sensitive adhesive; and evenly coating the pressure-sensitive adhesive onto a PET (polyethylene terephthalate) film, and drying at 100 DEG C for 1-5 minutes to obtain the pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape provided by the invention has the advantages of low cost, favorable matte effect, high stripping force, no adhesive residue after stripping, high viscosity and the like, and is applicable to packaging LED (light-emitting diode) digital tubes and dot matrix modules.
Description
Technical field
The present invention relates to a kind of pressure sensitive adhesive and Pressuresensitive Tape, refer in particular to a kind of rubber pressure-sensitive adhesive and Pressuresensitive Tape.
Background technology
At present, the Pressuresensitive Tape that is used for the encapsulation of LED charactron and lattice module mostly is the organosilicon type, the main raw material that is pressure sensitive adhesive is silicon rubber and silicone resin, the Pressuresensitive Tape cost that utilizes this pressure sensitive adhesive to make is high, atomized surface effect is not good, and peeling force is low, in use easily produces the glue phenomenon of overflowing.
Summary of the invention
The object of the present invention is to provide a kind of pressure sensitive adhesive that addresses the above problem and Pressuresensitive Tape, enable to reduce costs, the Pressuresensitive Tape atomized surface effect that obtains is good, peeling force is high and peel off after do not stay cull.
The objective of the invention is to be achieved through the following technical solutions:
Pressure sensitive adhesive of the present invention comprises the raw material of following weight part: 40～75 parts of natural rubbers, 10～30 parts, styrene-butadiene rubber(SBR), 5～10 parts of paracrils, 10～20 parts of acrylic elastomers, 20～50 parts of terpine resins, 10～30 parts of carbon five resins, 10～30 parts, resol, 0.1～1 part of isocyanic ester.
The preparation process of pressure sensitive adhesive is as follows:
(1) take in proportion natural rubber, styrene-butadiene rubber(SBR), paracril, acrylic elastomer, plasticate after mixing;
(2) mixture after plasticating is dissolved in organic solvent fully;
(3) add remaining raw material in proportion in organic solvent, after stirring 20～30h, and get final product.
Organic solvent described in step (2) is toluene or dimethylbenzene.
In the preparation method of pressure sensitive adhesive of the present invention, plasticating is an operation of Rubber processing well known in the art, refers to adopt the method for machinery or chemistry, reduces rubber molecular weight and viscosity improving its plasticity-, and obtains suitable mobility.
The preparation method of Pressuresensitive Tape: above-mentioned pressure sensitive adhesive is coated on the PET film equably, toast 1～5min in the time of 100 ℃ after, and be get final product.
Pressuresensitive Tape of the present invention is applicable to the encapsulation of LED charactron and lattice module, the suitable environment temperature is-10～100 ℃, compare with organosilicon type Pressuresensitive Tape, reduced cost, and have that atomized surface effect is good, peeling force is high and peel off after do not stay the advantages such as cull, viscosity be strong.
