Abstract
The invention relates to a tape, in particular to a self-adhesive tape with improved performance and an improved structure. The cold-pressed self-adhesive tape comprises a PET (polyethylene terephthalate) film layer, a bonding agent layer, a cotton paper layer and an emulsion layer sequentially from top to bottom. The cold-pressed self-adhesive tape which adopts the PET film as a substrate layer and has superior tensile strength and good toughness is provided.
Description
Technical field
The present invention relates to adhesive tape, be specifically related to a kind of single-coated foam that improves performance and structure.
Background technology
The single-coated foam of colding pressing is a kind ofly under less reactive force, just can form more firmly bonding force.The bonding force of single-coated foam is mainly Van der Waals force, and therefore, after bonding plane forms, the structure of gluing of surfaces can be not destroyed.Single-coated foam is to presser sensor, do not need heating, do not need solvent, do not need larger pressure, only need pressurize a little or with pointing once by realizing bonding a kind of adhesive tape.Be characterized in gluing being not difficult, shelling and not damaging of easily, taking off.
But in existing cold-pressed adhesive tape, multiplex kraft paper, as substrate layer, causes the shortcomings such as adhesive tape thickness is thickeied, and it is not strong that adhesive tape has toughness, and tensile strength is poor like this.And be wrapped on a round core when cold-pressed adhesive tape, while being bent to form an adhesive tape disc, because kraft paper thickness is larger, cause entire volume length of tape shorter.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of taking PET film as substrate layer, there is the single-coated foam of colding pressing of good tensile strength, good toughness.
Technical problem to be solved by this invention is achieved by the following technical programs:
The one single-coated foam of colding pressing, is followed successively by PET rete, binder layer, cotton paper layer, emulsion layer from top to bottom.
Further, described binder layer is acrylic pressure sensitive glue-line.
Further, described acrylic pressure sensitive glue-line is made up of the component of following parts by weight:
25 ~ 35 parts of butyl acrylates;
120 ~ 140 parts of Isooctyl acrylate monomers;
15 ~ 23 parts of vinyl acetate between to for plastics;
4 ~ 7 parts of methacrylic acids;
4 ~ 7 parts of Rocryl 410s;
2 ~ 4 parts of glycidyl methacrylate;
1 ~ 3 part of acrylamide;
0.1 ~ 0.3 part of Diisopropyl azodicarboxylate;
0.3 ~ 0.5 part of dibenzoyl peroxide;
65 ~ 90 parts of toluene;
100 ~ 130 parts of ethyl acetate;
1 ~ 5 part of isocyanic ester.
Further, described emulsion layer is genuine milk glue-line.
Further, described genuine milk glue-line is made up of the component of following parts by weight:
80 ~ 120 parts of natural emulsions;
20 ~ 40 parts of rosin milks;
1 ~ 3 part of p-cresol and dicyclopentadiene copolymer.
Further, described PET thicknesses of layers is 20 ~ 30 μ m.
Further, described binder layer thickness is 18 ~ 25 μ m.
Further, described cotton paper layer thickness is 15 ~ 20 μ m.
Further, described emulsion layer thickness is 15 ~ 20 μ m.
Traditional single-coated foam of colding pressing is using kraft paper as substrate layer, and the thickness of single kraft paper is just greater than 100 μ m; And in the present invention, contriver adopts PET film as substrate layer, its thickness is less, but itself and the gluing polar phase of genuine milk are poor large, cause bonding force poor, easily come unstuck.Therefore, contriver increases acrylic pressure sensitive glue-line and cotton paper layer cleverly in the middle of PET rete and genuine milk glue-line.Utilize the effect of acrylate pressure sensitive adhesive that PET film and cotton paper can be connected and composed successively; In addition, natural emulsion can be combined closely with cotton paper layer by rolling technology again, and natural emulsion has obvious infiltration effect on cotton paper, can further strengthen bonding force between the two, strengthens sticking power.Finally form the single-coated foam of colding pressing using PET film as substrate layer.
The present invention has following beneficial effect:
The single-coated foam of colding pressing of the present invention is just sticky little, when use two adhesive tapes to sticky, firm pasting, clinging power >=5N/in, pastes easily, retentivity is good, without cull, good toughness, tension is effective, tensile strength >=150N/in does not have phenomenon of rupture.And the single-coated foam thin thickness of colding pressing of the present invention, entire volume length of tape, up to more than 1000 meters, can greatly be enhanced productivity and reduce production costs.
