9.5；
B, add melamine：It is subsequently added into 35-37 parts of melamine, is gradually heated up, 1.5-2 DEG C of heating rate/min is warming up to
3-5 parts of 64 parts of formaldehyde catching agent and diethylene glycol (DEG) are added at 65 DEG C；
C, cloud and mist point is detected：After there is cloud and mist point, detection water number reaches 1.1-1.2, and caprolactam is added, and formaldehyde catching is added
PH9 .5-9.6 are adjusted in 64 parts of agent, cooling, and cooling is at 40 degree hereinafter, heat preservation is shut down；
3）Body paper uncoiling；
4）It prewets：Pre- wet practice is carried out to fibrous paper in the coiled uncoiling process of body paper；
5）Dipping：First match dipping glue in dipping process, dipping glue is to use step（1）100 parts of urea formaldehyde glue, the bleeding agent of synthesis
1-2 parts of 0.2-0.5 parts, 0.4-0.6 parts of curing agent and formaldehyde catching agent are stirred, and the fibrous paper prewetted is passed through leaching
Stain slot carries out comprehensive dip operation to it, has impregnated metering；
6）Drying, spraying：Spraying glue is prepared before spraying, spraying glue is to use step（2）100 parts of the modification triamine glue of synthesis,
0.15-0.35 parts of curing agent, 25-40 parts of white fused alumina, 0.05 part of coupling agent are stirred, first drying fibrous after having impregnated
Paper is sprayed spraying glue, is sprayed using steam auxiliary in spraying process after drying；
7）Drying, coating：Coating glue is first prepared before coating, coating glue is to use step（2）The modification triamine glue 100 of synthesis
Part, 0.15-0.35 parts of curing agent, 0.08-0.15 parts of releasing agent, 2-3 parts of plasticizer and 1-2 parts of formaldehyde catching agent are stirred
It forms；By drying, being coated, dry again after having sprayed, macromolecule composite abrasion resistance material is formed；
Be coated with leading portion drying temperature be 135-145 DEG C, drying time 3min, coating process using first cool down heat up again by the way of apply
Cloth, 122-135 DEG C, coating duration 4min has been coated with, then 120-140 DEG C of the temperature dried, then drying time 2min；After described
Section dries 135-140 DEG C of high-temperature region temperature, 125-135 DEG C of middle warm area drying temperature, 120-125 DEG C of low-temperature space drying temperature again；
8）It cuts, examine storage.
