Embodiment 1

[0021] The coniferous pulp and broad-leaved pulp with a total mass of 1000kg are crushed into the pulp pool according to the mass ratio of 1:3, and after mixing 20% ​​liquid red pigment and 2% liquid yellow pigment relative to the dry pulp mass, dilute 10 times with water, Filter into the pulp with a 100-mesh mesh, stir thoroughly for 5 minutes, then filter a 15% titanium dioxide solution relative to the dry pulp mass into the pulp with a 50-mesh mesh, fully stir for 10 minutes, and then refine the pulp. Refining adopts deflagging machine and double-disk mill in series, first deflaking and then cutting, the degree of refining is controlled at 38-40°SR, after pulping, put the pulp into the filling tank for filling, and then add PAE in turn 、AL 2 (SO 4 ) 3 And silicone defoamer, the amount of PAE added is 5% of the mass of the milled pulp, AL 2 (SO 4 ) 3 The addition amount is 0.5% of the mass of the milled pulp, and the addition amount of the silicone defoamer is 0.3% of t...

Embodiment 2

[0023] Crumble the coniferous pulp and broadleaf pulp with a total mass of 1000kg into the pulp pool at a mass ratio of 1:4, mix 10% liquid green pigment and 7% liquid yellow pigment relative to the dry pulp mass, and dilute 15 times with water , filter into the slurry with a 200-mesh mesh, take 0.3% of the powdered yellow pigment relative to the quality of the dry pulp, filter it into the slurry with a 200-mesh mesh, stir for 10 minutes, and then put 20% of the mass of the dry pulp The titanium dioxide solution was filtered into the slurry with a 100-mesh mesh, fully stirred for 8 minutes, and then refined. Refining adopts deflagging machine and double-disk mill in series, first deflaking and then cutting, the degree of refining is controlled at 38-40°SR, after pulping, put the pulp into the filling tank for filling, and then add PAE in turn 、AL 2 (SO 4 ) 3 And silicone defoamer, the amount of PAE added is 10% of the quality of the milled pulp, AL 2 (SO 4 ) 3 The additi...

Embodiment 3

[0025] The coniferous pulp and broad-leaved pulp with a total mass of 1000kg are crushed into the pulp pool according to the mass ratio of 1:3.5. After mixing 25% liquid red pigment and 4% liquid yellow pigment relative to the dry pulp mass, dilute it with water 12 times. Filter into the pulp with a 150-mesh mesh, fully stir for 8 minutes, then filter 40% of the titanium dioxide solution relative to the dry pulp mass into the pulp with a 80-mesh mesh, fully stir for 5 minutes, and then refine the pulp. Refining adopts deflagging machine plus double disc mill in series, first deflaking and then cutting, the debonding degree of pulping is controlled at 38-42°SR, after pulping, put the pulp into the filling tank for filling, and then add PAE in turn 、AL 2 (SO 4 ) 3 And silicone defoamer, the amount of PAE added is 8% of the mass of the milled pulp, AL 2 (SO 4 ) 3 The addition amount is 0.6% of the mass of the milled pulp, and the addition amount of the silicone defoamer is 0...

Abstract

The invention belongs to the field of a papermaking technology and specifically relates to a method for raising color fastness and brilliance of plain-colored decorative base paper. The method comprises the following steps: smashing softwood pulp and hardwood pulp into a pulp chest; selecting a pigment, diluting 10-15 times by adding water, filtering the pigment with a meshed of 100-200 meshes and putting the filtered pigment into a repulping tank, stirring for 5-10 min until the pigment is fully adhered to fiber; pumping stirred titanium dioxide into the repulping tank and stirring for 5-10 min, and grinding, wherein a fluffer and a double disc refiner are connected in series for grinding, the mode of cutting before defibering is adopted, and beating degree of grinding is 38-42 degrees SR; beating pulp into a filling tank for filling after grinding and successively filling PAE, a retention agent and an antifoaming agent; and finally adjusting concentration and pH value, and beating pulp into a machine chest to prepare for papermaking. By the method, use amount of the pigment is minimized, and production cost is reduced. Pigment cost accounts for a high proportion in dark plain-colored paper cost. Thus, the method is beneficial to cleaning of the meshed and coarse cotton cloth, and service life of the meshed and coarse cotton cloth is prolonged; the method is beneficial to treatment of sewage; and the processed plain-colored decorative base paper is bright in color and satisfies customers.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a method for improving the color fastness and vividness of plain decorative base paper. Background technique [0002] Plain decorative base paper refers to the decorative base paper that is pressed directly after impregnation. It has the characteristics of many varieties and bright colors. However, in the traditional production process, there are many disadvantages such as large loss of pigments, large consumption, serious water pollution, high production costs, and not bright colors. With the continuous competition in the market and the enhancement of environmental protection awareness, enterprises have proposed the concept of energy saving and consumption reduction, and zero discharge of sewage. Standards, to improve the production process in response to this phenomenon. Contents of the invention [0003] The purpose of the present invention is to provide a m...
