Description
Technical field
The present invention relates to a kind of preparation method of polyurethane Protection glue band, more precisely it is related to and is coated with polyacrylate
The preparation method of the polyurethane elastomer Protection glue band of pressure sensitive adhesive.
Background technology
Protection glue band is exactly the diaphragm for being coated with pressure sensitive adhesive, with its protection materials surface, prevents from scratching, pollutes.One
As be made with polyester film, polyethylene film, be coated with pressure-sensitive acrylate water, generally with less peeling force.
Recently as Protection glue band Enlargement, there is resistant to elevated temperatures polyimides pressure sensitive adhesive tape, aerospace purposes
Polyurethane elastomer pressure sensitive adhesive tape etc..
Polyurethane elastomer Protection glue band mainly utilizes the high tensile strength of polyurethane elastomer, mechanical resistant abrasion and table
Surface wear is moderate, and tear-resistant function admirable, hardness is high and oxytolerant, the features such as ozone performance is excellent.It is coated with polyacrylic resin
The polyurethane elastomer Protection glue of pressure sensitive adhesive is with puncture-resistant, tear, abrasion and corrosion and ultraviolet resistance, suitable for protection height
In warm alternation operation or static body surface, protected object body surface face is prevented to be subjected to corrosion, wear and small impact damage.
Presently commercially available polyurethane Protection glue band, it is usually that acrylic resin pressure sensitive adhesive is applied in a particular embodiment
Cloth covers PET film (high temperature resistance polyester film) or polypropylene paper or general on elastic polyurethane body thin film above glue
Peeling paper for users to use.To not being restricted from the residue peeled by protection surface.On this point in aerospace industry
Application aspect just be special requirement, it is desirable to by protection surface there is no the residue of acrylic resin pressure sensitive adhesive.For up to this
Purpose must make in-depth study.
The content of the invention
The present inventors do not allow acrylic resin pressure to allow polyurethane Protection glue band to be stripped down from by protection surface
Quick glue residua on the protected surface, has made a large amount of investigation, carries out process modification, recipe determination work, it is proposed that below
Complete technical scheme.
A kind of preparation method of polyurethane Protection glue band, the polyurethane Protection glue band is successively by 0.3~0.5mm of thickness hydroxyl
Base blocked polyurethane elastic film, 3 μm of primers of thickness and 0.07~0.09mm of thickness polyacrylate pressure-sensitives and anti-sticking stripping
Formed from paper；Preparation process is：Releasing agent is removed with solvent scouring hydroxyl terminated polyurethane elastic film, increase pressure sensitive adhesive is with gathering
Cohesive force between urethane elastic film, after solvent volatilizees 1~2min, bottom is coated with hydroxyl terminated polyurethane elastic film
Glue, hydroxyl terminated polyurethane elastic film have the poly- of anti-sticking peeling paper of the one side of primer with being coated with polyacrylate pressure-sensitive
The multiple patch of acrylate pressure-sensitive adhesive one side, then winds, for users to use；Anti-sticking peeling paper is peelled off during construction, the anti-sticking stripping peeled
From there is no polyacrylate pressure-sensitive residue on paper；Polyurethane Protection glue band peels from protected face, is equally being protected
Also without the residue of polyacrylate pressure-sensitive on mask；Polyurethane Protection glue band has 180 ° of 350~720N/ of peel strength
m；30~60 DEG C, 95% hydrothermal aging of relative humidity one week are arised from adherend one, and at -20~+20 DEG C, relative humidity exists
95%, under the conditions of temperature alternating aging for a week, also without the residue of polyacrylate pressure-sensitive on adherend surface.
Heretofore described hydroxyl terminated polyurethane elastic film, its NCO:OH=0.98~1.04, molecular weight 30000
~50000, the width and length of hydroxyl terminated polyurethane elastic film are not restricted, and require to prepare according to user.
Heretofore described polyacrylate pressure-sensitive composition includes：The weight % of methyl acrylate 80~85, acrylic acid
The weight % of butyl ester 7~10, Isooctyl acrylate monomer 4~5 weight %, the weight % of azodiisobutyronitrile 0.4~0.6 and with acrylate
The weight summation of all acrylate is 100 parts by weight meters in pressure sensitive adhesive composition, 10 parts by weight tackifying resins；Described polypropylene
The solid content of acid esters pressure sensitive adhesive is 30 weight %, and viscosity is 3000~5000 centipoises.
Heretofore described tackifying resin is chosen any one kind of them from terpene resin, coumarone indene resin or rosin resin.
Heretofore described solvent is to be chosen any one kind of them from acetone, butanone, cyclohexanone or two kinds of mixture.
Heretofore described primer be Shanghai Xiong Ye Industrial Co., Ltd.s provide the primer of product designation 5168, concentration
For 1 weight %.
Heretofore described primer be Shanghai Xiong Ye Industrial Co., Ltd.s provide the primer of product designation 5168, concentration
For 1 weight %.
Anti-sticking peeling paper used in patent of the present invention is directly commercially.
The present inventors once tested to search out the primer of the suitable present invention it may be said that making strenuous efforts and use epoxy
Resin adhesive, polyurethane water-based pressure-sensitive adhesive etc. all without preferable effect is obtained, was selected, selected several from the market again later
Kind adhesive is all undesirable, just selectes the glue of product designation 5168 by lot of experiments and screening, this glue possesses selected
Two conditions, it can increase the cohesive force of acrylate pressure-sensitive adhesive with elastic polyurethane film strong bond, and can, that is, reduce
Peel strength, cause to strip down from adherend body surface face, also without cull on adherend body surface face.So 5168 primers
It is preferable primer.
The elastic polyurethane film Protection glue band for implementing to prepare according to the present invention, has 180 ° of 350~720N/ of peel strength
M, after 30~60 DEG C, 95% hydrothermal aging of relative humidity one week, and at -20~+20 DEG C, relative humidity is 95%, temperature
Under the conditions of alternation aging for a week etc., stripped down from adherend surface, there is no the residue of glue on adherend surface.
