Chemical hardwood pulp, fibrous raw material used in sandwich layer are the bleached chemical needles that weight ratio is respectively 5-25%, 40-80%, 15-35%
Wood pulp, bleached chemical hardwood pulp, chemical bleaching thermomechanical pulp；
B. by sizing mixing, screening, purified face, core, three layers of bottom slurry upper net forming respectively；In forming process of surfing the Internet, veil, core
Net, spacer screen are respectively equipped with spraying device, and the over dry substance of sprayed auxiliary agent is starch, sodium phosphate and disodium edta,
Its group of dispensed weight number are as follows: 80-90 parts of starch, 10-20 parts of sodium phosphate, 0.5-2.0 parts of disodium edta；Forming net
The additive amount that portion is sprayed over dry substance is 20-50 kg/ton of paper；
C. three layers of face, core, bottom slurry are compound by composite roll after wet end removing partial moisture molding, bond using squeezing
Together；
D. the paper after compound carries out top sizing by dry, soft calendaring before top sizing, in which:
The adjuvant used middle over dry material composition of top sizing is starch, collagen, copolymer in cinnamic acrylic ester and chlorination
Sodium, each component parts by weight are respectively as follows: 60-80 parts of starch, 10-20 parts of collagen, copolymer in cinnamic acrylic ester
10-20 parts, 2-5 parts of sodium chloride；Surface-sizing station over dry substance additive amount is 30-60 kg/ton of paper；
The collagen is made for gelatin hydrolysis, relative molecular mass 3000-6000；
E. finally after top sizing drying, press polish, batch paper be made into.
Preferably, the quantification of 20g/ ㎡ -40g/ ㎡ of the surface layer, the quantification of 40g/ ㎡ -80g/ ㎡ of sandwich layer, bottom are quantification of
20g/㎡-40g/㎡。
Preferably, with slurry that wet reinforcing agent Polyamide Epoxy, cationic starch, wet reinforcing agent polyamide are added in the process
Epoxy resin additive amount is 0.05-0.50 kg/ton of paper, and cationic starch additive amount is 5-25 kg/ton of paper.
