Description of the invention (1) ™ ~ This invention relates to coating a fiber with a coating composition containing two or more mineral pigments Paper base to achieve paper quality improvement. In order to have a high-quality printing effect on fibrous paper materials such as paper or cardboard, it is usually necessary to apply at least one layer on the surface of the material: for example: kaolin, calcium carbonate, calcium sulfate, titanium dioxide, barium sulfate, forging light A coating composed of one or more mineral pigments such as white. Since the application of such coating composition can improve the smoothness, gloss, pure whiteness and milkiness of the surface of the material, it also improves the printing quality. In many cases, in order to have the expected good print quality on the final coating, it is usually necessary to apply two or more pigment-containing coating compositions on the paper surface. In order to maximize the investment cost of the paper coating machine, the operation of the coating machine is set at the highest possible cotton speed. In addition, since the composition of the coating contains pigments, adhesives, or other solid ingredients that may be suspended in water, the water in the composition must be evaporated to keep the coating dry. In order to reduce the energy consumption required for the evaporation process to a minimum, it is most desirable to have the highest solid concentration in the coating composition, but after observation, it was found that when the paper substrate has high water absorption and the coating composition With a high solids concentration, the knife used to remove the excess coating composition and the slip coating will cause scratches and other damage to the final coating. The purpose of the present invention is to provide two or more layers of coating on the fibrous paper substrate; t, and can also obtain a high-quality final coating composition with a high solid concentration at the high cotton speed of the coating machine coating. It is commonplace to add dewatering chemicals to the manufacture of fibrous paper products (please read the precautions on the back before filling in this page). Order 4

The water absorption of paper products can be controlled by the "gluing process". The conventional gluing method has two methods, namely internal gluing and surface _. In the internal gluing process, the fiber pulp is firstly formed before the paper is formed. Mixing the water-removing agent, and starch is usually used as the water-removing agent in the surface sizing process. 1 The cotton paper of the formed paper is subjected to "sizing and pressing", and the process is coated with the water-removing agent, usually gluing the surface In the manufacturing process, a layer of water-removing agent is applied on both sides of the cotton silk. 9 The most widely used sizing agent in the internal sizing process is rosin. When aluminum sulfate is added to the fiber suspension, the rosin will precipitate. However, after this treatment, the acid-base value of the fiber suspension will fall to pH 4 ~ 6, which makes the test filler such as calcium carbonate unsuitable for addition to the suspension. In order to be able to perform sizing operations on fibrous paper materials 1 containing alkaline earth fillers, sizing agents have been developed to have dewatering properties in neutral or alkaline fiber suspensions. These sizing agents include the alkyl ketene dimers disclosed in U.S. Patent No. 2627477 and the alkenyl succinic anhydrides disclosed in U.S. Patent No. 3102064. The present invention relates to an improved method for coating a fibrous paper material that has been previously coated with at least one layer containing an inorganic pigment coating layer and then coating the last layer with an inorganic pigment coating layer.

After the coating instrument is started, the drying curve drawn by the reflective intensity against time is also recorded by the computer. A typical drying curve should have an initial value of near zero reflective intensity when the blade passes through the light and the detector. After that, when the wet coating receives the light source, there will be a rapidly increasing reflective intensity, and As the coating dries, its reflective intensity will begin to decrease and form a certain value after it is completely dried. For each sample, the drying rate is represented by a drying parameter 6, which is derived from the curve drawn by the rate of change of the light intensity versus time, and δ represents when the wet coating is exposed to light for the first time The most known positive intensity gradient of the reflected intensity and the time interval between the maximum negative intensity gradient of the reflected intensity when the wet coating is partially dried and the maximum change rate of the reflected intensity 0 The Ministry of Economic Affairs Central Standards Bureau Printed by the consumer cooperative ---- 1 ---- f Installed ------- ordered (please read the precautions on the back before filling this page) As shown in Figure 1 to Figure 3, there are six The data chart of the drying parameter 5 caused by the samples of the first coating composition under different weights of the second coating.

Each paper sample with the first coating must be coated again as follows Composition of the second coating of the formula: Fine composition of calcium carbonate pigment styrene Diene latex carboxymethyl sodium cellulose optical phosphor weight ratio 100 12 1 0.5 (please read the precautions on the back before filling in this page). The same. Except for the glazing agent, the use of other ingredients is the same as the implementation. For example, the second coating is also applied by using a guide type coating machine with a coating roller and a blade. The blade pressure is kept constant so that the weight of the second coating layer becomes 9 g / m2. Whether there are any scratches on the coating can be detected by the following procedure: a first coating is first used on a paper sample that has been coated with a first coating that does not contain alkyl ethane snapper dimer, This second coating forms a coating weight of 9g / m2 with the maximum solid concentration under the cotton silk speed of 300m / min, and then increases the cotton silk speed to have a scratch on the blade, when the scratch occurs , Replace the paper substrate with a paper substrate that has been coated with a first coating containing an alkyl vinyl dimer, and apply the second coating under the same mechanical operating conditions, if the blade is scored If it doesn't appear again, increase the speed of the silk whisking. 11 This paper standard is suitable for China Associate (CNS) A4 size (210X297 mm)

However, if there are only 0.02 parts of Hyun-based ethylene dimer in the first coating, even if the second coating has a solid concentration of 68% ~ 69%, the reduction of the score is quite obvious . Under the same conditions, if the first coating has only 0_1 parts of alkyl ketene dimer, the printed bag 305800 A7 B7 for the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs The scratches on the coating can be completely eliminated. Example 3 A water-absorbent non-wood paper substrate with a unit weight of 94g / m2 is used and pre-coated with three different formulations of the first coating composition, the formulation of the three compositions is as follows: 1. 100 parts by weight of calcium carbonate pigment A; 15 parts by weight of oxidized corn starch. 2. 100 parts by weight of calcium carbonate pigment B; 15 parts by weight of oxidized corn starch; 0.6 parts by weight of sodium salt of styrene-maleic acid copolymer. 3. 100 parts by weight of calcium carbonate pigment A; 15 parts by weight of oxidized corn starch; 0.25 parts by weight of alkenyl succinic anhydride. &Quot; Calcium carbonate pigment A is the same as the object used in the composition of the first coating * in Example 1. Calcium carbonate pigment B is a natural marble and after crushing it has the same small particle size as pigment A, but its solid concentration in the liquid suspension is low and no dispersant is present. The object of use of the oxidized corn starch is the same as in Example 1. The sodium salt of the styrene-maleic acid copolymer is produced by Atochem; the trade name is SMA 3000. The succinic acid liver is produced by Claymore Chemicals Limited; the trademark is CLAYSIZE PR4. In each experiment, before adding the corn starch solution containing 30% corn starch, the corn starch solution must be heated at 90 ° C for 20 minutes. 13 The paper size is applicable to the Chinese National Standard (CMS) A4 specification (210X 297 ^) ^ Xi Order (please read the precautions on the back before filling in this page) A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5.
