Abstract
The invention discloses special pressure-sensitive self-adhesive glue for confidential letters. The glue comprises components in percentage by weight as follows: 45%-68% of natural rubber, 0.5%-3% of abietate and like substitutes, 0.4%-1.3% of ammonia and like substitutes and 31.1%-50.7% of water. Due to the fact that natural rubber is added to the glue, the special pressure-sensitive self-adhesive glue for the confidential letters has characteristics of no sticking to paper and a printer toner cartridge, and a bonding action can be generated only by exerting a little more pressure when only two adhesive surfaces are contacted; a confidential letter adopting the pressure-sensitive self-adhesive glue can pass a printer successfully and is sealed, convenience is realized, and the confidential letter producing efficiency is increased effectively.
Description
Technical field
The invention relates to the formula of glue, be applicable to the special pressure sensitive self-adhesive of the close letter of one of all kinds of printer, be specially adapted to the special pressure sensitive self-adhesive that secret stamped envelope makes.
Background technology
The special letters of some band security informations all need sealing to transmit, as bank cipher, individual bill etc.And the sealing compound of letters has saliva glue, non-setting adhesive and pressure glue at present, saliva glue, as envelope, needs water just can bond, and non-setting adhesive such as emitting red envelope seals, but saliva glue, non-setting adhesive all can cause serious injury to printer as adopted during printer type information, and make efficiency is extremely low; And although the secret letter of pressure glue can adopt printer type information, need the letter sheet machine of specialty could seal shaping.
Adopt the secret letter of this production that all kinds of printer both can have been adopted to print relevant information, the letter sheet machine press seal again without the need to specialty is shaping, and only the pressing of needs finger just can make secret letters shaping, not only convenient but also quick.
Summary of the invention
The object of this invention is to provide the special pressure sensitive self-adhesive of a kind of close letter, both can reach the effect just can clung with pressure, can ensure again to damage printer.
For achieving the above object, solution of the present invention is:
The special pressure sensitive self-adhesive of a kind of close letter, its component according to weight ratio is: natural rubber 45%-68%, rosin ester and similar generation product 0.5%--3%, ammonia and similar generation product 0.4%--1.3% and water 31.1%-50.7%.
The similar Dai Pinwei petroleum resin emulsion of described rosin ester and mixture.
The similar Dai Pinwei monoethanolamine of described ammonia, diethanolamine, trolamine and mixture.
After adopting such scheme, the close letter pressure sensitive special adhesive prepared owing to adding natural rubber in glue of the present invention, it has not sticky paper and opens the characteristic with printer toner cartridge, and just can produce adhesive effect when only having two glue faces to contact, the letters with pressure sensitive self-adhesive of the present invention so can be made to pass through printer smoothly, seal again, effectively improve the efficiency of close letters producing.
Embodiment
Present invention is disclosed the special pressure sensitive self-adhesive of a kind of close letter, its component according to weight ratio is: natural rubber 45%-68%, rosin ester and similar Dai Pin (as petroleum resin emulsion etc. and mixture): 0.5%--3%, ammonia and similar Dai Pin (as monoethanolamine, diethanolamine, trolamine etc. and mixture) 0.4%--1.3% and water 31.1%-50.7%.
Add the toner cartridge adhesion that this natural rubber can prevent glue and other paper or printer here, only have during two glue face contacts and just produce adhesive effect, the letters with pressure sensitive self-adhesive of the present invention so can be made smoothly by printer, then seal, effectively improve the efficiency of close letters producing.Glue of the present invention is applicable to any printer, and as laser, ink-jet, wire printer, and the seal break-off of paper reaches more than 95%.
