Abstract

The invention provides a method for making colored laser paper and a colored laser paper thereof, the method comprises the following steps: slurry forming, pulping, paper making, applying glue on surface; a formed slurry selects a broad leaf chemical bleaching sulfate slurry, a dispersant B is added in applying glue starch during the process of applying glue on the surface. The colored laser paper is produced by the broad leaf chemical bleaching sulfate slurry, which is characterized in that the ash content is 5%-30%, the water content is 4%-7% and the smoothness is 8 sec/10cc. The colored laser paper is smooth, the phenomena of paper blocking can be avoid, the film forming ability of a surface oil membrane is good, the requirement of high definition quality can be guaranteed during high speed printing.

Description

A kind of coloured silk swashs paper papermaking process and paper

Technical field

The present invention relates to paper technology, especially a kind of coloured silk swashs paper papermaking process and paper.

Background technology

Along with paper technology constantly develops, paper plant develops a series of paper kinds that satisfy particular customer, and its sharp paper of prizing arises at the historic moment; Providing of the grade of living now, people are increasingly high to the printing effect quality requirements.The vividness of common printing paper color, saturation degree and everyway have satisfied not the requirement of modern printer, because color sharp paper all differs from common printing paper, lucuriant in design, the image fidelity of its printing effect in optics rerum natura, surface physical property, intensity rerum natura etc.

Common print paper is generally kept surface strength of paper and certain water repelling property in direct coating surface size-press starch of paper surface and conventional Cypres; Because the appearance of now high article printer; It is just passable that paper is required not only to satisfy these requirements, also requires when high speed, high-quality printing, can cross machine, non-paperboard fast; Printed matter surface oil film film forming will be got well; And stronger in the paper surface bond strength than common paper, could guarantee that like this effect that paper prints is more excellent, let picture and text have kind to appear vividly effect on paper.

Summary of the invention

In order to overcome technical problem of the prior art, the invention provides a kind of coloured silk and swash paper papermaking process and paper, this paper had both satisfied the requirement of water repelling property, satisfied at a high speed the effect during high-quality the printing again.

A kind of coloured silk swashs the paper papermaking process, may further comprise the steps:

Step a: join slurry, select broad-leaved chemical bleaching NBSK for use, add additive A in the slurry process of loosing;

Step b: making beating, manufacture paper with pulp;

Step c: top sizing adds dispersant B in size-press starch.

As preferred version, said additive A is ethyl group acrylates or acrylates.

As preferred version, said additive A is adding in 4-8 hour before manufacturing paper with pulp.

As preferred version, said broad-leaved chemical bleaching NBSK making beating back freedom is 300-500ml.

As preferred version, said dispersant B is the cellulose ether base polymer, CMC, one of PVA.

As preferred version, said size-press starch is 20-50kg/t, and dispersant B is 10-30kg/t.

As preferred version, the resin added of said step c is 3-5gsm.

As preferred version, can also comprise steps d: become the paper whiteness.

A kind of paper is processed by broad-leaved chemical bleaching NBSK, it is characterized in that ash content is that 5%-30%, moisture content are that 4%-7%, smoothness are 80sec/10cc.

As preferred version, add two sulphur OBA in the said paper, the surface is six sulphur OBA.

After implementing above technical scheme, has following technique effect.

1. in diffusing slurry process, add additive A, be used to improve smoothness, make the surface more level and smooth, avoid paperboard, phenomenon such as heavily send to take place, satisfy the requirement of flying print.

2. in the top sizing process, add dispersant B, be used for improving sur-face peeling intensity, and the sea surface oil slick good film-forming property, when flying print, still can guarantee high image quality.

3. in becoming paper whiteness process, in add and adopt two sulphur OBA, surface to adopt six sulphurs, reduce the influence of electric charge to the control system.

The specific embodiment

Be described further below in conjunction with embodiment.

Embodiment one

A. join slurry: select broad-leaved chemical bleaching NBSK 100% (like Eucalyptus, yearning between lovers wood, poplar etc.) for use, in the slurry process of loosing, add the additive A (ethyl group acrylates, acrylates etc.) of 1-5kg/t paper.Because broad-leaved chemical bleaching NBSK cell membrane is thin, roughness is low; Not only even, can also improve smoothness of paper, additive A is used for moistening the fiber that rises; Improve and promote smoothness; The additive A consumption can be done suitably adjustment according to paper quality, preferably before paper machine making 4-8 hour, fully contacts with medicine to satisfy fiber; After the fibre swelling joint of refining energy consumption fallen and system keeps and some keep auxiliary agents joint and fall the influence that positive aspects is all arranged.

B. making beating, manufacture paper with pulp: owing to require the evenness index request higher, preferred broad-leaved chemical bleaching NBSK making beating back freedom is 300～500ml.Owing to adopt leaf wood chemical bleaching NBSK to manufacture paper with pulp, paper strength is actual to change before copying that great changes have taken place, therefore in the process of manufacturing paper with pulp, will suitably control the speed of a motor vehicle; Because smoothness is had relatively high expectations, the control of moisture content control, press polish pressure and the calendering temperature of the process of manufacturing paper with pulp is particularly important.

C. top sizing: in size-press starch; Add dispersant B (cellulose ether base polymer, CMC, PVA) in (cornstarch, tapioca, wheaten starch) and improve sur-face peeling intensity; Size-press starch is used 40-50kg/t paper; Dispersant B adds 20-25kg/t paper, must guarantee that paper surface has the 3-5gsm resin added.

D. become the paper whiteness: become the paper whiteness to have relatively high expectations, in add and adopt two sulphur OBA, surface to adopt six sulphur OBA, come suitable control system electric charge with this, avoid a large amount of uses of fluorescer very big to system's charge affects, can have a negative impact to whole manufacturing paper with pulp.Add two sulphur OBA 4-10kg/t, surperficial six sulphur OBA 4-10kg/t in preferred.

The one-tenth paper ash is divided into 25%-30%, moisture content is that 4%-7%, smoothness are 80sec/10cc.

Embodiment two

The difference of present embodiment and embodiment one is that in the top sizing step, size-press starch is 30-40kg, and dispersant B is a 15-20kg/t paper.

The one-tenth paper ash is divided into 20%-25%, moisture content is that 4%-7%, smoothness are 80sec/10cc.

Embodiment three

The difference of present embodiment and embodiment one is that in the top sizing step, size-press starch is a 20-30kg/t paper, and dispersant B is a 10-15kg/t paper.

The one-tenth paper ash is divided into 15%-20%, moisture content is that 4%-7%, smoothness are 80sec/10cc.

What should explain is; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
