Detailed description of the invention
In order to more clearly explain the technical solutions in the embodiments of the present application, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, the drawings in the following description are only some examples of the present application, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.Wherein:
Fig. 1 is a kind of flow diagram of one embodiment of preparation method of carbonless copying paper microcapsule of the application.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, rather than whole embodiments.Based on this
Embodiment in application, those of ordinary skill in the art are obtained every other under the premise of not making creative labor
Embodiment shall fall in the protection scope of this application.
Carbonless paper is a kind of procrypsis carbon paper, has the function of directly making carbon copies, directly develop the color.Its colour developing is main
It is: under external force, the quick pigment of the power in microcapsules (i.e. leuco dye) and oil solution (i.e. solvent naphtha) is made to overflow and develop the color
Staining reaction occurs after agent contact, to play the role of manifolding.It is mainly used for multiple part form, bill, continuous wealth ticket, general industry
Business wealth ticket etc..There are two types of coating in carbonless paper: the CF layer (code name CF, i.e. Coated Front) containing color developing agent and containing
There is the CB layer (code name CB, i.e. Coated Back) of colour former.Colour former is a kind of special leuco dye, is dissolved in non-volatile
Solvent naphtha in, it is microencapsulated by 3-7 μm.The surge firmly write and printed can crush microcapsules, make
Leuco dye solution outflow is contacted with color developing agent, chemical reaction occurs, colored graph text is presented, to achieve the purpose that manifolding.With three
For the carbonless paper receipt of connection, paper, middle paper, lower paper can be divided into.Upper paper is also known as carried on the back and applies paper (code name CB), the back side of paper
It is coated with the microcapsules of the quick pigment oil containing power；Middle paper is also known as positive and negative double paintings paper (code name CFB, i.e. Coated Frontand Back),
Recto is coated with color developing agent, and the back side is coated with the microcapsules of the quick pigment oil containing power；Lower paper is also known as face and applies paper (code name CF), and paper is only
It is coated with color developing agent.
Microcapsules are the important components of carbonless paper, largely control the quality of carbonless paper.
The preparation method of microcapsules is usually using natural or synthetic macromolecule filming material finely dispersed solid particle, liquid
Or gas coats to form minute solid particles.Wherein, it is wrapped in the substance inside microcapsules and is known as core material, the packet outside microcapsules
Overlay film is known as wall material.
Wherein, core material is leuco dye and solvent naphtha, and leuco dye is dissolved in solvent naphtha.Write or printing when generate compared with
Big pressure, microcapsules are crushed, and so that the solvent naphtha containing leuco dye is flowed out and is absorbed by the coating on lower layer's paper, in turn
It is contacted with color developing agent, chromogenic reaction occurs, to achieve the purpose that manifolding.
In current techniques, carbonless paper microcapsules generally use melamine resin and polyurethane resin as wall
Material, the two contain formaldehyde and isocyanates respectively, there is different degrees of pollution, and the latter's higher cost to environment.Therefore, exist
Domestic 95% or more carbonless paper uses melamine resin.Present inventor is in long-term R&D process, discovery
Melamine resin is because of only one carbon body paper connection between melamine rings, and rigidity is larger, and the brittleness of wall shell is big, is transporting
It is easily broken during defeated, is easy to produce paper pollution problem.Meanwhile preparing melamine resin using formaldehyde as raw material,
Therefore, production process and not environmentally, and the microcapsules produced may contain residues of formaldehyde object, to mucocutaneous irritating
Effect.
In view of the above-mentioned problems, the application provides a kind of carbonless paper environmental-friendly microcapsule, it is based on parts by weight, carbon-free multiple
