A discongests pure wood pulp, pull an oar, and makes concentration and be 3.5% ~ 4.0%, beating degree is the slurry of 18 ~ 20oSR;
Then b discongests the terylene chemical fibre, and it is mixed with slurry that step a obtains, obtains the mixed slurry that concentration is 2 % ~ 2.5%, and the addition of terylene chemical fibre is the 2%-3% of mixed slurry gross mass;
C mixes add wet strength agent and polyethylene glycol oxide in mixed slurry after, and then through oblique net papermaking net part forming, press dewatering, vat be dry, batch, rewind slitting, obtains the papermaking body paper;
The d body paper is the gluing coating behind coating machine dipping, then drying, batch, cutting and rewinding, obtain and the paper self-adhesive tape body paper.
The surface temperature of drier of described vat drying is controlled at 107 ℃ of-113 ℃ of scopes.
The addition of described terylene chemical fibre is 2.5% of mixed slurry gross mass, and the concentration of mixed slurry is 2.5%.
The addition of described wet strength agent is 3.0% ~ 3.2% of mixed slurry gross mass.
It is to bear 27 ℃ latex that vitrification point is adopted in described gluing coating.
Described pure wood pulp is the northern wood pulp of Canada.
The spread of described gluing coating is controlled at 10 ~ 12g/m
2Scope.
The invention has the beneficial effects as follows: the present invention adds polyethylene glycol oxide (PEO) in mixed slurry, has improved the formation of sheet and the pliability that make body paper; In mixed slurry, add the terylene chemical fibre, improve pliability and the tensile strength of body paper; Utilize oblique net paper machine to manufacture paper with pulp, the paper uniformity when having guaranteed coating; Directly rolling behind large cylinder dried declines to a great extent cost in the paper-making process.It is soft as cotton with its paper of paper self-adhesive tape body paper that technique of the present invention obtains, and machine direction tensile strength is greater than 25N/cm, and thickness 0.06 ~ 0.07mm has good water permeability resistance, high-temperature aging resisting performance.
