Abstract
The invention relates to a dyeing process of an olive-green insulating paperboard. The dyeing process adopts the following raw material prescriptions: (a) raw material: 1,000kg of 100 percent softwood pulp board accounted by dry pulp; (b) dye: 0.50+/-0.01 percent: 1.2kg/1,000kg pulp+/-0.0025 percent of direct turquoise blue and 3.8kg/1,000kg pulp+/-0.0075 percent of alkaline bright yellow; and (c) a fixing agent: 20kg/1,000kg pulp of aluminum sulfate.
Description
Technical field
The present invention relates to a kind of insulation industry with the dyeing in the production process, belong to the dyeing technical field.
Background technology
The industrial insulating board production process of existing dyeing mostly is pulping and adds dyestuff later on, and contains the alkaline bright yellow of easy oxidation in the dye formulation, and the cardboard color homogeneity of manufacturing paper with pulp out like this is poor, and surface oxidation-resistant is poor, with the passing of time fugitive color.And the client requires relatively strictness to the cardboard color, and stable for guaranteeing product color, colour-fast nondiscolouring must be chosen stain, reserves prescription, formulates optimised process.
Summary of the invention
The objective of the invention is to select chemical staining reagent for use at the wood pulp plant cellulose, find out rational Recipe, the alkaline bright yellow that fades at easy oxidation adds the aluminum sulfate that can play tint retention, and coloring agent is added in in the paper pulp before the slurry process, by with the mixing of paper pulp, grinding, fixation, produce the cardboard that meets customer demand.
The object of the present invention is achieved like this: after earlier the raw material wood-pulp board being added water to the hydrabrusher size degradation, dewater to former stock tank through decker, the dyestuff that has mixed up is added former stock tank, stir with slurry, send into paste mill grinding with stock pump again, the slurry that mill is good enters machine chest, again the aluminum sulfate color-fixing agent that mixes up is joined machine chest with slurry stirs, for the paper machine use of next procedure.
Dye formulation:
A, paper pulp raw material: wood pulp cellulose
B, dye dosage:
Direct bright blue 1.2kg/1000kg slurry ± 0.025 ‰
Alkaline bright yellow 3.8kg/1000kg slurry ± 0.075 ‰
C, color-fixing agent consumption: aluminum sulfate 20 ± 1 ‰
The cardboard color even that the present invention produces, colour-fast for a long time under high temperature and sunlight, this dye technology retention height, permeability waste water strong, that discharge be limpid, can handle with paper waste, realizes qualified discharge, the purpose that dye dosage is few, simple to operate.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Its products' realization process is: as shown in Figure 1, after earlier the raw material wood-pulp board being added water to the hydrabrusher size degradation, to former stock tank, the dyestuff that has mixed up is added former stock tank through the decker dehydration, stir a period of time with slurry, mix, send into three tandem double disc refiner defibrinations with stock pump again, the slurry that mill is good enters machine chest, color-fixing agent aluminum sulfate is suitably dissolved again, reach colour fixation, for the paper machine use of next procedure.
The composition of raw materials of this technology is (by the 1000kg oven dry stock):
A, raw material: 100% needlebush pulpboard 1000kg (oven dry stock meter)
B, dye dosage: 5.0 ± 0.1 ‰
Direct bright blue 1.2kg/1000kg slurry ± 0.025 ‰
Alkaline bright yellow 3.8kg/1000kg slurry ± 0.075 ‰
C, color-fixing agent consumption: aluminum sulfate 20kg/1000kg slurry.
Claims (1)
1. the dyeing of an olive-green insulating paperboard, it is characterized in that: the composition of raw materials of this technology is:
A, raw material: 100% needlebush pulpboard 1000kg, by oven dry stock;
B, dye dosage: 5.0 ± 0.1 ‰;
Direct bright blue 1.2kg/1000kg slurry ± 0.025 ‰;
Alkaline bright yellow 3.8kg/1000kg slurry ± 0.075 ‰;
C, color-fixing agent consumption: aluminum sulfate 20kg/1000kg slurry.
