Containing a concentration of 80wt%~95wt% wood pulps and the ultrashort terylene fibers of a concentration of 5wt%~20wt%, slurry concentration 2.0wt%
~2.5wt%；
C) add in paper wet strength agent and softening agent into slurry, mixing, through inclined wire papermaking wet end former it is wet-formed →
Squeezing and suction box dehydration → and through carrying roller enter vat preliminary drying → two cylinder drying → soft calendaring press polish → volume → rewind slitting, it obtains
Body paper；
2) dip coated and release：
The coated machine dip coated of body paper, spread are controlled in 12g/m2~14g/m2In the range of, through bridge drying tunnel prebake
First of painting process is completed in → drying cylinder optical press roll press polish → cylinder dried → cooling cylinder cooling；After first of painting process and then
Reverse side surface coating is carried out, reverse side of paper carries out applying mould release release treatment, and release dosage control is in 2.5g/m2~3.5g/m2,
Through drying, → cooling cylinder cools down → batches → cutting and rewinding, obtains transfering tape and impregnates release paper product.
A kind of optimization for the present invention, with the oven dry stock gauge of pure wood pulp, the dosage of softening agent for paper for 0.1wt%~
0.3wt%, the dosage of wet strength agent is 0.4wt%~0.6wt%.
For a kind of optimization of the invention, the surface temperature of drier of vat preliminary drying is controlled at 67 DEG C -73 DEG C in step c), greatly
The water content control for obtaining semi-finished product body paper of cylinder preliminary drying is in 12%-18%, then by calender press polish.
A kind of optimization for the present invention, step 2) is middle to use glass transition temperature to be coated for -40 DEG C of latex.
A kind of optimization for the present invention, the pure wood pulp are the wooden wood pulp in Canada north.
A kind of optimization for the present invention, wet strength agent is Polyamide Polyamine Epichlorohydrin Resin.
A kind of optimization for the present invention, softening agent for paper is cationic surface active agent.
The present invention impregnates release paper compared with background technology, by transfering tape made from this technique, and paper is longitudinally anti-
Zhang Qiangdu up to reaches more than 8.35% to 40N/cm, cross direction elongation, and flexibility is good, vertically and horizontally pulling force compares than small, paper
Difference smaller paper in two sides is bright and clean uniformly, glue good attachment, solves the problems, such as that the domestic transfering tape that can not produce impregnates release paper.
