Abstract
The invention provides digital carbonless copying paper. Curtain coating is carried out on the carbonless copying paper. A coating comprises the following components in parts by weight: 2-5 parts of light calcium carbonate, 5-9 parts of sodium carboxymethyl cellulose, 4-9 parts of styrene-butadiene emulsion, 5-10 parts of polyamine polyepoxy resin, 10-15 parts of melamino-formaldehyde resin, 11-14 parts of styrene-acrylic copolymer, 10-18 parts of carboxylic butadiene-styrene latex, 1-3 parts of sulphonated castor oil, 7-16 parts of sodium polyacrylate, 12-18 parts of polyvinyl alcohol, 1-5 parts of kaolin, 1-4 parts of corn starch, 1-3 parts of pigment, 4-7 parts of emulation, 3-5 parts of argil, 5-12 parts of titanium dioxide and 4-12 parts of talcum powder. According to the invention, after the technical measures are adopted, as the digital carbonless copying paper parts can be automatically separated and leaves of each paper part are firmly bonded, requirements of clients are satisfied.
Description
Technical field
The present invention relates to the no carbon paper of paper industry made.
Background technology
Before the present invention proposes, because the use of digital carbonless copy paper does not need plate-making as common printed, reduce society to the demand of flexographic, further reduce the demand to oil.Owing to adopted the process of curtain coating chemical coating, in order to keep the continuity of curtain, need to add a certain amount of interfacial agent, to reduce the surface tension of coating, satisfy the continuous operation of coating machine, keep production continue carry out.Simultaneously, the interpolation of interfacial agent, also so that the contact angle of paper reduces, hydrophily strengthens, the infiltration of paper glue will be high than other paper, be used after the separation gel, part with part between separate, become very difficult owing to adhesion strength is too high; And the page or leaf of every part of inside and the adhesion strength between the page or leaf are inadequate, can not bond preferably each other, become on the contrary to separate easily.
Summary of the invention
The technical problem to be solved in the present invention is to overcome deficiency of the prior art, proposes a kind of digital carbonless copy paper.
The present invention is achieved by the following technical measures.
A kind of digital carbonless copy paper, carry out curtain coating in no carbon paper, coating is comprised of following parts by weight of component, precipitated calcium carbonate 2-5 part, sodium carboxymethylcellulose 5-9 part, styrene-butadiene latex 4-9 part, polyamine gathers epoxy resin 5-10 part, melamine resin 10-15 part, styrene-acrylic is pump polymers 11-14 part altogether, carboxylic styrene butadiene latex 10-18 part, sulfated castor oil 1-3 part, Sodium Polyacrylate 7-16 part, polyvinyl alcohol 12-18 part, kaolin 1-5 part, cornstarch 1-4 part, pigment 1-3 part, latex 4-7 part, carclazyte 3-5 part, titanium dioxide 5-12 part, talcum powder 4-12 part.
After the present invention adopts abovementioned technology, the method with curtain coating will be coated on the page of digital carbonless copy paper through the coating of optimization process.Be used separation gel, make to have the printed matter of gathering leaves of a book, part with part between can automatically separate, bonding is firm between the page or leaf of every part of centre and the page or leaf, satisfies client's demand.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
