Description
Technical field
The invention belongs to organic pressure-sensitive gel technical fields, and in particular to a kind of water of fire-resistant isinglass belt silicone adhesive
Property lotion and preparation method thereof.
Background technique
Fire-resistant isinglass belt silicone adhesive is developed based on organic pressure-sensitive gel.Organic pressure-sensitive gel be by
The synthetic product of MQ silicone resin and hydroxy-terminated polysiloxane, it not only have good adhesion strength necessary to pressure sensitive adhesive and
Tack, there are many more unique performances, and the spy less than other pressure-sensitive adhesives is especially shown in terms of low temperature and high temperature
Property.Apply the silicone adhesive on fireproof mica band in addition to having the advantages of common pressure sensitive adhesive, it is also necessary to higher cohesion
Intensity, peel strength, viscosity and solid content and low tack are provided simultaneously with the characteristics of burning does not carbonize, Mica Tape Adhesive master
It to be primary raw material by MQ silicone resin and high-viscosity 107 glue, by the related process such as catalytic polymerization and adjustment raw material proportioning, with suitable
Answer different requirements.In conclusion fire-resistant isinglass belt silicone adhesive is synthesized on the Process ba- sis of organic pressure-sensitive gel
Quick-drying, high adhesion firmness silicone adhesive suitable for mica tape bonding.
Fire-resistant isinglass belt adhesive needs very low viscosity when in use, usually 70-100mpas, and common solvent has
Toluene, dimethylbenzene, dichlorotoleune, petroleum ether, cyclohexanone and its mixture.These solvent type fire-resistant isinglass belt silicone adhesives
Toluene or dimethylbenzene used in agent etc. is all the stronger diluent of toxicity, pollutes environment, can also bring when in use to human body
Injury.For the environmental issue for solving fire-resistant isinglass belt adhesive, Chinese patent CN201310188544.0 discloses a kind of environmental protection
Type high-temperature resistant silicone pressure-sensitive adhesive, component include 30-50 parts of organic silicon rubber, 50-70 parts of MQ organic siliconresin, are catalyzed
0.01-0.1 parts of agent, 60-70 parts of solvent, the solvent is the lipid of low molecular weight, not only transparent but also environment-protecting and non-poisonous, is used
Be all low molecular weight or more low-boiling solvent, it is poor to the dissolubility of organic pressure-sensitive gel, in adhesive tape production after gluing
The non-volatile gradient of solidification process volatilization, the pressure sensitive adhesive tape being made into are easy to produce surface blemish, and transparency is bad, and are easy residue glue.
Chinese patent CN106398636A uses the environmentally friendly solvents such as PMA, DBE, EGDA and acetate butyl, nontoxic to the human body, avoids ring
Border pollution, in addition, arranging in pairs or groups to form high low-boiling solvent combination by PMA, DBE, EGDA and butyl acetate, so as to organosilicon
The dissolubility of pressure sensitive adhesive is more preferable, and in adhesive tape production, gluing post cure processes solvent forms suitable volatilization gradient, manufactured Asia
Sensitive tape surface is more smooth, transparency.Both silicone adhesives above mainly directly use the rouge of low molecular weight
Class or part use the lipid of low molecular weight, to dissolve the silicone adhesive of macromolecule, although environment-protecting and non-poisonous, all
Certain stimulation taste, and it is not easy infiltration and quick-drying rapidly.
