Description
Technical field
The present invention relates to a kind of White Board.
Background technology
Business rotary press has the fast characteristic of print speed, per hour prints 35000 ~ 110000, is 6 ~ 20 times of common offset machine. Mode of printing, certainly will require that printing can rapid drying so fast. When paper passes through the baking oven of rotary press, paper surface temperature reaches about 120 ~ 200 DEG C, and the moisture content of paper inside is expanded by heating under this high bake, shows as paper bubbling phenomenon, and this seriously have impact on the efficiency of rotary printing.
For the paper temperature tolerance of rotary printing usually more than 180 DEG C, and common White Board heatproof is generally at 150 ~ 160 DEG C. In order to meet the heatproof requirement of rotary printing paper using, paper temperature tolerance is promoted in the industry at present mainly through improving the methods such as body paper fiber consumption, employing high porosity pigment, control moisture content, aforesaid method not only increases paper production cost and reduces the utilization ratio of timber, neither energy-conservation also not environmentally.
Summary of the invention
In view of this, it is necessary to providing a kind of White Board, its temperature tolerance well can avoid bubble problem during rotary printing.
A kind of White Board, it at least one coating layer comprising body paper, forming the glue application layer on body paper surface and form glue application layer surface, the body paper of this White Board, glue application layer, at least one coating layer have at least one containing calcined kaolin, 70% ~ 95%, the ISO whiteness accounting for calcined kaolin total mass that wherein this calcined kaolin particle diameter is less than or equal to 2 ��m is more than or equal to 85%; The addition manner of this calcined kaolin in body paper adds as papermaking filler for replacing part papermaking filler, and wherein the addition of calcined kaolin is the 10% ~ 40% of over dry stock quality; The addition manner of this calcined kaolin in glue application layer for add calcined kaolin in table glue liquid, and the addition of calcined kaolin is the 20% ~ 70% of table glue liquid quality; The addition manner of this calcined kaolin in coating layer adds as coating pigment for part replaces coating pigment, and its addition is the 10% ~ 90% of coating pigment quality.
The barrier property that the present invention utilizes calcined kaolin high temperature resistant and outstanding, substantially improving common rotary printing paper using temperature tolerance not enough, the phenomenons such as rotary printing foaming, make full use of the pigment crystalline form of calcined kaolin simultaneously, improve top coat covering performance, improve the smooth property of paper. When maintaining identical rotary printing, greatly reduce production cost, high speed business rotary printing industry is brought far-reaching influence.
Embodiment
The White Board of the present invention is used for rotary printing, it at least one coating layer comprising body paper, forming the glue application layer on body paper surface and form glue application layer surface.
The slurry that the preparation of this body paper adopts is the combination of one or more in vitriol bleach chemical pulp, Alkaline Peroxide Mechanical Pulp or pulp from decoloured waste paper, and wherein in slurry, the mass ratio of vitriol bleach chemical pulp, Alkaline Peroxide Mechanical Pulp, pulp from decoloured waste paper is (60 ~ 100): (0 ~ 30): (0 ~ 10). Slurry is through the obtained body paper of paper technology step of routine, the paper technology step of this routine specifically comprise successively making beating, with slurry, in add, upper net forming, squeezing drying and other steps, add the material that step adds in wherein and include papermaking filler and other chemical agent various. Reach conventional beating degree through each slurry kind of making beating process, it is specially: vitriol bleach chemical pulp 30 ~ 45 �� of SR; Alkaline Peroxide Mechanical Pulp 20 ~ 30 �� of SR; Pulp from decoloured waste paper 40 ~ 50 �� of SR.
The body paper of this White Board, glue application layer, coating layer have at least one containing a certain amount of calcined kaolin.
The performance of calcined kaolin, it is worth far away higher than common kaolin, has greatly widened the range of application of kaolin. The main purpose calcined by kaolin is: (1) sloughs organic carbon with other impure minerals to improve whiteness; (2) slough kaolin contained humidity, hydroxyl to improve void volume and the chemical reactivity of calcination product, improve physical and chemical performance, meet various application demand. Kaolin through calcination process is stripped of structure or crystal water, carbonaceous and other volatile matter thereof, becomes hard kaolinite, trade name " calcined kaolin ". Calcined kaolin has that whiteness height, unit weight are little, specific surface area and pore volume big, oil absorbency, opacifying property and wear resistance good, the characteristics such as insulativity and thermostability height.
The calcined kaolin of the present invention has certain effect of heat insulation. This calcined kaolin is characterized as 70% ~ 95%, ISO whiteness >=85% that particle diameter��2 ��m account for quality, and oil-absorption(number) is 60 ~ 70g(Viscotrol C)/100g(calcined kaolin), 325 order screenings��0.008%, pH=6.0 ~ 8.0, moisture content��1.5%. Wherein particle diameter and ISO whiteness are important to the influential effect of the present invention. The calcined kaolin size distribution with this particle diameter and ISO whiteness is narrower, specific surface area is big, there is excellent optical property and covering ability, pigment structure is loosened and porous, be conducive to moisture content Quick diffusing in paper, thus avoid when paper is dried owing to dispelling the heat inequality and causing great Mo district to print foaming phenomena.
The addition manner of this calcined kaolin in body paper is: the papermaking filler [such as water-ground limestone (GCC), light calcium carbonate (PCC)] replacing part conventional adds as papermaking filler, and wherein the addition of calcined kaolin is the 10% ~ 40% of over dry stock quality. The interpolation quality of filler in paper making pulp is convention amount.
The addition manner of this calcined kaolin in glue application layer is: add calcined kaolin in the table glue liquid of routine, and its addition is the 20% ~ 70% of table glue liquid quality, and the solid content of the table glue liquid being mixed with is 10% ~ 40%.
The addition manner of this calcined kaolin in coating layer is: part replaces conventional coating pigment (such as GCC, PCC, Clay) and adds as coating pigment, its addition is the 10% ~ 90% of coating pigment quality, and add other coatings additive(s)s conventional etc., being mixed with coating solids is 50% ~ 70%.
The coating that at least one coating layer forming body paper surface uses contains coating pigment 100 mass parts (comprising calcined kaolin), cationic starch 10 ~ 50 mass parts, latex 0 ~ 20 mass parts, white dyes 0 ~ 2 mass parts, Wet Strength Resin 0 ~ 0.5 mass parts, other auxiliary agent 0 ~ 0.5 mass parts and suitable quantity of water. Wherein above-mentioned each component is the formula of coating routine, does not describe in detail in this patent.
The coating process parameter of coating is specially: total glue spread is 15 ~ 60g/m2, calendering temperature 50 ~ 150 DEG C, line pressure 80 ~ 300KN, the speed of a motor vehicle 500 ~ 1500m/min.
This White Board be quantitatively 50 ~ 150g/m2, water content is 2.5 ~ 6.0%, whiteness >=88%, temperature tolerance >=180 DEG C, and paper smoothness is greater than 800s, through rotary printing without foaming phenomena.
The barrier property that the present invention utilizes calcined kaolin high temperature resistant and outstanding, substantially improving common rotary printing paper using temperature tolerance not enough, the phenomenons such as rotary printing foaming, make full use of the pigment crystalline form of calcined kaolin simultaneously, improve top coat covering performance, improve the smooth property of paper. When maintaining identical rotary printing, greatly reduce production cost, high speed business rotary printing industry is brought far-reaching influence.
