Description
Technical field
The present invention relates to a kind of preparation method of urethane protective tapes, more precisely relate to the preparation method of the polyurethane elastomer protective tapes being coated with polyacrylate pressure-sensitive.
Background technology
Protective tapes is exactly the protective membrane being coated with pressure sensitive adhesive, with its protecting materials surface, prevents from scratching, pollution etc.General utilization polyester film, polyethylene film are made, and coating pressure-sensitive acrylate water, has less peeling force usually.
In recent years along with protective tapes Enlargement, there is resistant to elevated temperatures polyimide Pressuresensitive Tape, the polyurethane elastomer Pressuresensitive Tape etc. of aerospace purposes.
Polyurethane elastomer protective tapes mainly utilize the high tensile strength of polyurethane elastomer, mechanical resistant to wear away and surface abrasion moderate, the high and feature such as oxytolerant, ozone excellent property of tear-resistant excellent property, hardness.Be coated with the polyurethane elastomer protective tapes puncture of polyacrylic resin pressure sensitive adhesive, tear, abrasion and corrosion and ultraviolet resistance; be applicable to protect high/low temperature alternation to run or on static body surface, prevent protected object surface from standing burn into wearing and tearing and little impact damage.
Urethane protective tapes commercially available at present; in a particular embodiment; be generally that acrylic resin pressure sensitive adhesive is coated on elastic polyurethane body thin film, on glue, cover PET film (high temperature resistance polyester film) or polypropylene paper or general interleaving paper for user.The residue peeled from protected surface is not restricted.About the application aspect of this point in space industry be just special requirement, require the residue not having acrylic resin pressure sensitive adhesive on protected surface.Deep research must be done for reaching this object.
Summary of the invention
The present inventors strip down from protected surface to allow urethane protective tapes; do not allow acrylic resin pressure sensitive adhesive residual on the protected surface, done a large amount of investigation, carried out process modification; recipe determination works, the technical scheme that existing proposition is complete below.
A preparation method for urethane protective tapes, this urethane protective tapes is made up of the hydroxyl terminated polyurethane Elastic Film of thickness 0.3 ~ 0.5mm, thickness 3 μm of primers and thickness 0.07 ~ 0.09mm polyacrylate pressure-sensitive and antiseized interleaving paper successively; Preparation process is: with solvent scouring hydroxyl terminated polyurethane Elastic Film removing releasing agent, increase the cohesive force between pressure sensitive adhesive and elastic polyurethane film, after solvent evaporates 1 ~ 2min, hydroxyl terminated polyurethane Elastic Film is coated with primer, hydroxyl terminated polyurethane Elastic Film has the one side of primer to paste with the polyacrylate pressure-sensitive one side of the antiseized interleaving paper being coated with polyacrylate pressure-sensitive is multiple, then rolling, for user; Peel off antiseized interleaving paper during construction, the antiseized interleaving paper peeled does not have polyacrylate pressure-sensitive residue; Urethane protective tapes peels from protected, does not also have the residue of polyacrylate pressure-sensitive equally on protected; Urethane protective tapes has 180 ° of stripping strength 350 ~ 720N/m; Arise from 30 ~ 60 DEG C, relative humidity 95% hydrothermal aging one week with adherend one, and at-20 ~+20 DEG C, relative humidity is 95%, and under temperature alternating aging one week condition, adherend does not have the residue of polyacrylate pressure-sensitive on the surface yet.
Hydroxyl terminated polyurethane Elastic Film described in the present invention, its NCO:OH=0.98 ~ 1.04, molecular weight 30000 ~ 50000, width and the length of hydroxyl terminated polyurethane Elastic Film are not restricted, and require preparation according to user.
Polyacrylate pressure-sensitive composition described in the present invention comprises: methyl acrylate 80 ~ 85 % by weight, butyl acrylate 7 ~ 10 % by weight, Isooctyl acrylate monomer 4 ~ 5 % by weight, Diisopropyl azodicarboxylate 0.4 ~ 0.6 % by weight and be 100 parts by weight with the weight summation of all acrylate in acrylate pressure-sensitive adhesive composition, 10 weight part tackifying resins; The solid content of described polyacrylate pressure-sensitive is 30 % by weight, and viscosity is 3000 ~ 5000 centipoises.
Tackifying resin described in the present invention is chosen any one kind of them from terpine resin, coumarone indene resin or Gum Rosin.
Solvent described in the present invention is chosen any one kind of them from acetone, butanone, pimelinketone or the mixture of two kinds.
Primer described in the present invention is the trade names that Shanghai Xiong Ye Industrial Co., Ltd. provides is 5168 primers, and concentration is 1 % by weight.
Primer described in the present invention is the trade names that Shanghai Xiong Ye Industrial Co., Ltd. provides is 5168 primers, and concentration is 1 % by weight.
The antiseized interleaving paper that patent of the present invention uses is directly commercially.
The present inventors make strenuous efforts in order to the primer searching out applicable the present invention, once tested with epoxyn, urethane water-based pressure-sensitive adhesive etc. does not all obtain desirable effect, selected from the market again afterwards, select good several tackiness agent all undesirable, just selecting trade names through lot of experiments and screening is 5168 glue, this glue has possessed two selected conditions, can with elastic polyurethane film strong bond, the force of cohesion of acrylate pressure-sensitive adhesive can be made again to increase, namely stripping strength is reduced, cause and strip down from adherend surface, cull is not had on adherend surface yet.So 5168 primers are desirable primers.
The elastic polyurethane film protective tapes prepared according to the invention process; there are 180 ° of stripping strength 350 ~ 720N/m; in 30 ~ 60 DEG C, relative humidity 95% hydrothermal aging is after one week; and at-20 ~+20 DEG C; relative humidity is 95%; under the conditions such as aging one week of temperature alternating, strip down on the surface from adherend, adherend does not have the residue of glue on the surface.
