Abstract
The invention discloses a production method of impregnated paper. The method comprises: step one, glue making; step two, glue preparation; step three, first impregnation: adding 30 parts of melamino-formaldehyde resin, 20-40 parts of urea-formaldehyde resin, and 1 part of an organic pigment into a glue impregnation trough; step four, first drying; step five, second impregnation: adding 30-40 parts of melamino-formaldehyde resin to reach a final procuring rate of 40-70%; and step six, second drying; step seven, cooling clipping. The organic pigment has the characteristics of bright color, strong tinting strength, small density, no toxicity, certain light fastness, heat resistance, solvent resistance and mobility resistance. During resin impregnation of plain-color paper, especially light-color paper, the adding of an organic pigment can blend the color of impregnated decorative paper, enhance paper plumpness, brightness, increase paper cover rate, and improve the aging resistance and the like of impregnated paper.
Description
Technical field
The present invention relates to the facing paper production field, particularly a kind of production method of impregnated paper.
Background technology
Enter the 21 century people and pursue material progress and cultural and ideological progress, melamine impregnated paper is because of oil resistant, and water-fast, durability against pollution is liked by people deeply by force.But facing paper is carried out behind the impregnation effect that sometimes color, paper hiding rare, plumpness and the vividness of paper do not reach demand.
Summary of the invention
The technical issues that need to address of the present invention are that the color of paper, paper hiding rare, plumpness and vividness do not reach the effect of demand sometimes after facing paper is carried out impregnation in the prior art.
For solving the problems of the technologies described above, the invention provides a kind of production method of impregnated paper, may further comprise the steps:
Step 1, glue, preparation dipping be with melamine resin and Lauxite, melamine resin pH value=8.5-9.2 wherein, solids content 51%, Lauxite pH value=8.5-9.2, solids content 49%;
Step 2, join glue;
Step 3, the first time flood, and add a certain amount of organic pigment, 30 parts of melamine resins, Lauxite 20-40 part, 1 part of organic pigment in steeping vat;
Step 4, dry for the first time;
Step 5, the second time flood, melamine resin 30-40 part, final precuring rate 40-70%;
Step 6, dry for the second time;
Step 7, cooling cutting.
As the preferred technical solution of the present invention, described melamine resin prescription is 1200 parts of melamines, formaldehyde 1300-1500 part, water 700-800 part, 4 parts of diethylene glycols, 2 parts of caprolactams; The concrete prescription of described Lauxite is 1000 parts in urea, formaldehyde 1800-2200 part, water 450-550 part.
The paper color that wherein changes according to hope, described organic pigment can be azo pigment, bisazo amide-type pigment yellow or pyroles paratonere.In the steeping vat that floods for the first time, add a certain amount of azo pigment, can improve facing paper outward appearance and performance; As want to allow the paper flavescence can add bisazo amide-type pigment yellow; As want to allow paper redden and to add the pyroles paratonere.
The present invention adds a certain amount of organic pigment in the steeping vat of dipping for the first time, organic pigment in bright gay color, and strong coloring force, density is little, and avirulence has certain fast light, heat-resisting, anti-solvent and resistance to migration.In the impregnating resin process to the especially light paper of plain color paper, add organic pigment, the color that can allocate dipping decorative paper also can improve the plumpness of paper, vividness, the hiding rare of increase paper improves impregnated paper ageing-resistant performance etc.
The specific embodiment
The below describes the preferred technical solution of the present invention in detail.
The production method of impregnated paper of the present invention may further comprise the steps:
Step 1, glue, preparation dipping be with melamine resin and Lauxite, melamine resin pH value=8.5-9.2 wherein, solids content 51%, Lauxite pH value=8.5-9.2, solids content 49%;
Step 2, join glue;
Step 3, the first time flood, and add a certain amount of organic pigment, 30 parts of melamine resins, Lauxite 20-40 part, 1 part of organic pigment in steeping vat;
Step 4, dry for the first time;
Step 5, the second time flood, melamine resin 30-40 part, final precuring rate 40-70%;
Step 6, dry for the second time;
Step 7, cooling cutting.
Wherein, described melamine resin prescription is 1200 parts of melamines, formaldehyde 1300-1500 part, water 700-800 part, 4 parts of diethylene glycols, 2 parts of caprolactams; The concrete prescription of described Lauxite is 1000 parts in urea, formaldehyde 1800-2200 part, water 450-550 part.
The paper color that wherein changes according to hope, described organic pigment can be azo pigment, bisazo amide-type pigment yellow or pyroles paratonere.In the steeping vat that floods for the first time, add a certain amount of azo pigment, can improve facing paper outward appearance and performance; As want to allow the paper flavescence can add bisazo amide-type pigment yellow; As want to allow paper redden and to add the pyroles paratonere.
The present invention adds a certain amount of organic pigment in the steeping vat of dipping for the first time, organic pigment in bright gay color, and strong coloring force, density is little, and avirulence has certain fast light, heat-resisting, anti-solvent and resistance to migration.In the impregnating resin process to the especially light paper of plain color paper, add organic pigment, the color that can allocate dipping decorative paper also can improve the plumpness of paper, vividness, the hiding rare of increase paper improves impregnated paper ageing-resistant performance etc.
