Abstract
The invention relates to adhesive tapes, specifically to a hot-pressed masking tape. The hot-pressed masking tape comprises, from top to bottom, a crepe paper layer 1, a polyurethane binder layer 2 and a hot melt adhesive layer 3. The hot-pressed masking tape provided by the invention has the advantages of good retentivity, no residual adhesive, good toughness, good tensile effect and high tensile strength, and is free of the phenomenon of fracture.
Description
Technical field
The present invention relates to adhesive tape, be specifically related to a kind of U.S. stricture of vagina paper hot pressing adhesive tape.
Background technology
Hot pressing adhesive tape is also known as Hot melt adhesive tape.It is different from pressure sensitive adhesive tape, and it is when room temperature, and hot pressing adhesive tape does not show pressure sensitive adhesion, and has resistance to blocking；But through the high temperature hot pressing of moment, just produce the cohesive force of 10 times of pressure sensitive adhesive tapes.But in the adhesive tape of the high thickness of existing needs, multiplex U.S. stricture of vagina paper is as substrate layer, but this substrate layer pastes poor performance with hot melt adhesive layer, it is easy to degumming.
Summary of the invention
It is good that the technical problem to be solved is to provide a kind of bonding force, not easily a kind of U.S. stricture of vagina paper hot pressing adhesive tape of degumming.
The technical problem to be solved is achieved by the following technical programs:
A kind of U.S. stricture of vagina paper hot pressing adhesive tape, is followed successively by U.S. stricture of vagina ply of paper 1, polyurethane binder layer 2, hot melt adhesive layer 3 from top to bottom.
Further, described polyurethane binder layer is made up of the component of following parts by weight:
PEPA 350 ~ 400 parts；20 ~ 30 parts of sulfamic acid sodium；Dibutyl tin laurate 1 ~ 3 part；Isocyanates 80 ~ 130 parts；Ethylenediamine 10 ~ 25 parts；500 ~ 880 parts of water.
Further, described hot melt adhesive layer is made up of the component of following parts by weight:
Ethylene ~ acetate ethylene copolymer 180 ~ 320 parts；Petropols 20 ~ 50 parts；0.2 ~ 4 part of age resistor.
Further, the VAM content of described ethylene ~ acetate ethylene copolymer is 20%, and MI value is 350.
Further, described U.S. stricture of vagina ply of paper thickness is 80 ~ 120 μm.
Further, described polyurethane binder layer thickness is 5 ~ 8 μm.
Further, described hot melt adhesive layer thickness is 10 ~ 15 μm.
In the present invention, U.S. stricture of vagina ply of paper is big with hot melt adhesive layer polarity spectrum, causes that adhesion is poor, it is easy to degumming.Therefore, inventor increases an adhesive for polyurethane layer at U.S. stricture of vagina ply of paper and hot melt adhesive layer cleverly and solves polarity spectrum greatly, and adhesion is poor, it is easy to the problem of degumming.
And in hot melt adhesive layer, the characteristic according to adhesive for polyurethane layer, so that both polarity are similar, it has on adhesive for polyurethane layer and significantly penetrates into effect, it is possible to strengthen adhesion between the two further, strengthens adhesive force.In the ethylene ~ acetate ethylene copolymer selected, VAM content is 20%, and MI value is 350, and the PUR intensity of preparation is high, improves adhesive strength.
And age resistor used in inventing is the age resistor that the art is conventional, it is preferred to four (3,5-di-t-butyl-4-hydroxyl) benzenpropanoic acid pentaerythritol ester.
There is advantages that
The U.S. stricture of vagina paper hot pressing adhesive tape retentivity of the present invention is good, and without cull, good toughness, tension is effective, and tensile strength is high, does not have phenomenon of rupture.
