Description
The present invention relates to high temperature resistant pressure sensitive adhesive band and preparation method thereof.
Before the present invention makes, many reports were arranged about high temperature resistant pressure sensitive adhesive band and preparation method thereof." preparation method of high temperature polyurethane contact adhesive band " (U.S.Pat.3,756,848 1973) introduced the high temperature resistant polyurethane contact adhesive band that the elastomeric reactant crosslinking curing of natural pale crepe or synthetic rubber and polymeric polyisocyanate and hydroxyl makes, energy heat-resisting 150 ℃, 30 minutes or 163 ℃, 17 minutes, the peelable cull that do not stay.It is serious that natural rubber surpasses 150 ℃ of degradeds, is difficult to using more than 150 ℃ with its pressure sensitive adhesive that is raw material is made, and solidifies by urethane crosslinks and can improve its thermotolerance.Present method technology is comparatively complicated, makes the also high temperature of ability more than 170 ℃ not of adhesive tape.Introduce the Pressuresensitive Tape made from the polyacrylic ester copolymer emulsion in " strippable Pressuresensitive Tape " (U.S.Pat.4,645,711 1987), have rippability,, peel off and do not stay cull in using below 150 ℃.The polyacrylate(s) high molecular polymer, when at high temperature holding under tension or compression, stress relaxation and metamorphism are remarkable, show the thermal ageing behavior of hardening after the first deliquescing, so difficulty is applied to surpass 150 ℃ of high temperature and loading is arranged and need localized occasion.If use method of modifying to improve its thermotolerance, will significantly increase the complicacy of preparation again and cost is risen.As " the high temperature resistant band that covers " (U.S.Pat.5,385,783 1995) introduce a kind of by (A) with the impregnated paper substrate of carboxylated synthetic rubber, (B) barrier coat, (C) contain the silane coupling agent and (D) Pressuresensitive Tape made of the pressure sensitive adhesive formed of natural rubber and acrylic rubber emulsion mixture, antioxidant and tackifier of mixture, natural rubber latex and the acrylic latex of carboxyl SBR latex, can not ftracture in anti-180 ℃, 20 minutes, do not stay cull.Its manufacturing process is comparatively complicated, needs to use multiple latex composite crosslinking, and manufacturing cost also will raise.Introduce JD-22 for the 380th page in " gluing application manual---splicing design and tackiness agent " (in March, 1994, the Electronic Industry Press published) book, the JD-24 Pressuresensitive Tape, be that a kind of organic silicone adhesive agent material is coated on the woven fiber glass of viton, its Good Heat-resistance, can below normal temperature to 200 ℃, use, but, be difficult to use in a large number as fixation adhesive tape because price is higher.
The purpose of this invention is to provide a kind of new high temperature resistant pressure sensitive adhesive band and preparation method thereof.The adhesive tape fine heat-resisting performance can anti-170 ℃, 30 minutes, and the peelable cull that do not stay is of many uses, and the preparation method is simple, production cost is low.
High temperature resistant pressure sensitive adhesive band of the present invention is by containing 100 parts of (weight parts, chlorinated butyl rubber down together), 1～6 part of linking agent zinc oxide, 2.5～20 parts of reactive alkyl phenolic resins of linking agent, 1～5 part of activator stearic acid, 2～10 parts of activator zinc resinates, 10～50 parts of tackifying resins such as terpine resin or petroleum resin, 6～40 parts of tenderizers such as straight chain saturation alkane or liquid terpine resin component, and be coated in the Pressuresensitive Tape of making on the heatproof goffered paper through the pressure sensitive adhesive after the crosslinking reaction.The heatproof goffered paper back side can scribble separant.
Its preparation method is:
1, with 100 parts of chlorinated butyl rubbers that are cut into small pieces, 1～6 part of linking agent zinc oxide, 2.5～20 parts of reactive alkyl phenolic resins of linking agent, 1～5 part of activator stearic acid and 2～10 parts of activator zinc resinates, 10～50 parts of tackifying resins such as terpine resin or petroleum resin, 6～40 parts of tenderizers such as straight chain saturation alkane or liquid terpine resin are dissolved in organic solvent such as stable hydrocarbon or the aromatic hydrocarbons, also can add a small amount of anti-aging agent, rising temperature for dissolving, carried out crosslinking reaction 1～6 hour in 60～100 ℃, make the even heavy-gravity pressure sensitive adhesive solution of khaki color, its viscosity is 1000～3000mpas, and it is 20～30% that the add-on of solvent makes the glue solid content that is made into.
2, on heatproof goffered paper, directly be coated with above-mentioned pressure sensitive adhesive solution, can carry on the back on the heatproof goffered paper and scribble separant.Can use industrial general solvent-borne type coating machine to be coated with, at 100～160 ℃, dry 1～5 minute, further crosslinking reaction made the high temperature resistant pressure sensitive adhesive band, then through rolling, cut and obtain high temperature resistant pressure sensitive adhesive band finished product.
Because having two on the major ingredient chlorinated butyl rubber molecular structure of the present invention can
(B) there is the chlorine of replacement atom to exist on the position, two keys of carbon atom on (A) position are activated, therefore, can select to use two kinds of different linking agents to form two kinds of cross-linking systems, control different crosslinked conditions, thereby obtain required resistance toheat.
The present invention is a kind of new high temperature resistant pressure sensitive adhesive band, and it just glues 〉=3
#Ball; 180 ° of stripping strength 〉=8N/25mm; hold sticking 〉=30min/12.5mm for 0 °, oven test (adhesive tape 12.5mm * 12.5mm, loading 100 gram) reaches 170 ℃, 30min and does not come off; peel off and do not stay cull; 230 ℃ of heat-resistant limit tests, 15min do not come off, and peel off and do not stay cull, can be suitable for the anchor leg as electronic components such as electrical condenser, resistors; braid is produced, and also can be used for the purposes of covering protection and the high temperature resistant stickup of other needs of printed-wiring board (PWB) welding.Preparation method of the present invention compared with prior art, technology is simple, easy to operate, the reaction times is short, constant product quality, production cost is lower, is easy to realize suitability for industrialized production.
Most preferred embodiment of the present invention:
