Abstract
The invention discloses a production method of pattern synchronously matched 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 0.5 part of a wet strength agent into a glue impregnation trough; step four, paper stretching for achieving an expected value; step five, first drying; step six, second impregnation: adding 30-40 parts of melamino-formaldehyde resin to reach a final precuring rate of 40-70%; step seven, second drying; and step eight, cooling cutting. The wet strength agent can enhance the strength of wetted paper, and usually, under the circumstances with no additive, the strength of wetted paper is only 5%-10% of that of the paper when it is dry. After adding the wet strength agent, the paper can be stretched to reach the expected value.
Description
Technical field
The present invention relates to the impregnated paper production technical field, particularly a kind of synchronously to spending the production method of impregnated paper.Background technology
Synchronously to flower namely in the dipping paper pressing laminate process pattern with the pattern on the facing paper and press adhering form board corresponding, suppress the concavo-convex technology that the decoration panel of third dimension, clean mark is arranged.Enter the 21 century people and pursue material progress and cultural and ideological progress, melamine impregnated paper is because oil resistant, water-fast, durability against pollution is liked by people deeply by force, but the match volume that does not have solid wood, synchronously the flower technology has been remedied this deficiency, yet the moisture absorption profit owing to decorating base paper rises in dipping process, facing paper and press adhering form board are difficult to reach synchronously to flower.
Summary of the invention
The technical issues that need to address of the present invention are that impregnated paper and the press adhering form board that prior art is produced is difficult to reach synchronously to flower.
For solving the problems of the technologies described above, the invention provides a kind of synchronous production method to the flower 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 wet strength agent, 30 parts of melamine resins, Lauxite 20-40 part, 0.5 part of wet strength agent in steeping vat;
Step 4, paper is stretched, to reach the value of expection;
Step 5, dry for the first time;
Step 6, the second time flood, melamine resin 30-40 part, final precuring rate 40-70%;
Step 7, dry for the second time;
Step 8, cooling cutting.
Wherein, described melamine resin prescription is 1200 parts of melamines, formaldehyde 1300-1500 part, 4 parts of water 600-750 part diethylene glycols, 2 parts of caprolactams; The concrete prescription of described Lauxite is 1000 parts in urea, formaldehyde 1800-2000 part, water 400-550 part; Described wet strength agent is cationic wet strength agent.
The present invention adds a certain amount of wet strength agent in the steeping vat that floods for the first time, wet strength agent can increase the intensity of paper after moistening, and generally, when not adding auxiliary agent, when its intensity only be dry after paper was wetted 5%～10% of intensity, paper can be stretched to reach the value of expection behind the interpolation wet strength agent.
The specific embodiment
The below describes the preferred technical solution of the present invention in detail.
Of the present invention synchronously to the production method of flower 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 wet strength agent, 30 parts of melamine resins, Lauxite 20-40 part, 0.5 part of wet strength agent in steeping vat;
Step 4, paper is stretched, to reach the value of expection;
Step 5, dry for the first time;
Step 6, the second time flood, melamine resin 30-40 part, final precuring rate 40-70%;
Step 7, dry for the second time;
Step 8, cooling cutting.
Wherein, described melamine resin prescription is 1200 parts of melamines, formaldehyde 1300-1500 part, 4 parts of water 600-750 part diethylene glycols, 2 parts of caprolactams; The concrete prescription of described Lauxite is 1000 parts in urea, formaldehyde 1800-2000 part, water 400-550 part; Described wet strength agent is cationic wet strength agent.
The present invention adds a certain amount of wet strength agent in the steeping vat that floods for the first time, wet strength agent can increase the intensity of paper after moistening, and generally, when not adding auxiliary agent, when its intensity only be dry after paper was wetted 5%～10% of intensity, paper can be stretched to reach the value of expection behind the interpolation wet strength agent.
For example not flood front width be 1243mm to facing paper, and width can reach the 1252mm width behind the normal dipping, as wants to allow the impregnated paper width reach 1255mm, then according to above-mentioned prescription, behind the dipping paper stretching 3mm carried out drying more for the first time.
