Embodiment 1
[0029] After preparing the materials, calculate according to the weight ratio: add 35 parts of softwood pulp fiber, 35 parts of hardwood pulp fiber, 5 parts of polyester fiber (1.67D, 6mm), control the online concentration at 0.3%, the beating degree: 30, and the amount is 82.5 g / m 2 .
[0030] Adopt Fourdrinier paper machine, one time coating (thermoplastic resin, 10kg) 16.5g / m 2 . Glue formulation: acrylic latex (SJ-2): acrylic latex (SJ-5) = 3:1, sizing amount is 10%;
[0031] After the glue is dried in an oven, use Fourdrinier paper machine to second glue 11g / m 2 , The sizing amount is 6%. Gluing liquid formula: LN-F1 type oil repellent: modified AKD neutral glue: modified dispersed rosin glue = 3:2:1.
[0032] Calender with a soft calender; roll paper rewind packaging.
[0033] The paper index is as follows:
[0034] Quantitative 110g / m 2 , Thickness 14S, longitudinal dry tension 177N, transverse dry tension 150N, transverse expansion rate: 0.8%.
Embodiment 2
[0036] After preparing the materials, calculate according to the weight ratio: add 35 parts of softwood pulp fiber, 32 parts of hardwood pulp fiber, 10 parts of polyester fiber (1.67D, 6mm), control the online concentration at 0.3%, and the quantitative 92g / m 2 .
[0037] One time coating inside the machine (modified thermoplastic resin) 14g / m 2 . Glue formulation: acrylic latex (SJ-2): acrylic latex (SJ-5) = 3:1;
[0038] 14g / m for the second glue coating inside the machine 2 . Gluing liquid formula: LN-F1 type oil repellent: modified AKD neutral glue: modified dispersed rosin glue = 3:2:1.
[0039] The paper index is as follows:
[0040] Quantitative 120g / m 2 , Thickness 15S, longitudinal dry tension 185N, transverse dry tension 153N, transverse expansion rate: 0.85%.
[0041] Finally, the high-grade water-resistant sandpaper made of water-resistant sandpaper base paper has good water resistance, flexibility, solvent resistance (resistance to adhesives in sandpaper production), dime...
