Abstract
The invention discloses a method for making environmental-friendly low-quantification high-endurability coated duplex boards with grey backs. The method for making the environmental-friendly low-quantification high-endurability coated duplex boards with grey backs adopts a unique raw material ratio, a slurry ratio and a paper making method by a paper machine, so as to solve the contradiction between low-quantification and high-endurability of coated duplex boards with grey backs made from waste paper, the bursting strength of the produced environmental-friendly low-quantification high-endurability coated duplex boards with grey backs is larger than 460 Kpa, and the bursting index reaches up to more than 2.2 Kpa*m2/g, at the same time, the quantification of the coated duplex boards with grey backs is within the range from 193 to 207 g, and the thickness is within the range from 220 to 240 [mu]m. The method for making the environmental-friendly low-quantification high-endurability coated duplex boards with grey backs is great breakthrough and improvement of production of environmental friendly paper in the paper industry, and the method is suitable for popularization and application.
Description
Technical field
The present invention relates to paper technology, be specifically related to the preparation method of the high resistance to broken coated duplex board with grey back of a kind of environment-friendly type light basis weight.
Technical background
At present, along with printing and the development of packaging industry, the requirement of market to speciality paper is more and more higher, is particularly the enterprises in pulp and paper industry of raw material with waste paper, low grammes per square metre and high bursting strength become coated duplex board with grey back produce in a great problem.
Summary of the invention
The object of the invention is to solve is at present the problem that the low grammes per square metre that exists in the making coated duplex board with grey back technology of raw material and high bursting strength cannot get both with waste paper, provides the preparation method of the high resistance to broken coated duplex board with grey back of a kind of environment-friendly type light basis weight.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
The preparation method of the high resistance to broken coated duplex board with grey back of a kind of environment-friendly type light basis weight comprises the steps:
(1) pulp furnish: starch adhesive is the high whiteness high-cleanness, high Deinking Pulp that Mixed Office WasteMOW is produced; Lining is that this type of wastepaper as raw material bulk is good, and air permeability is high, can improve the bulk of lining waste paper pulp with mechanical pulp raw material for leading the Japanese 3# of 40% old and useless newspaper and 60% of manufacturing paper with pulp, U.S. useless 37#; Sandwich layer is the waste and old corrugation boxboard of 60% mixed waste paper and 40%, can improve the bursting strength of sandwich layer waste paper pulp; Bottom is the mixed waste paper fluff pulp of 50% old and useless newspaper and 50%;
(2) paper machine is manufactured paper with pulp wet end furnish: surface layer is 70% leaf wood bleached kraft pulp and 30% Mixed Office WasteMOW slurry; Lining is 100% Deinking Pulp; Sandwich layer is 100% mixed waste pulp, and wherein fluff pulp and long fine slurry respectively account for half; Bottom is 50% Deinking Pulp and 50% mixed waste paper fluff pulp;
(3) paper machine pulping method: screen cloth slurry network speed respectively faster than surface layer flow rate of slurry, lining flow rate of slurry, base pastes flow velocity/slow 3 ~ 5 meters; Screen cloth slurry faster/slow than center stock flow velocity 1 ~ 3 meter of network speed; Hard press polish linear pressure is 50 ~ 80KN/m; Soft calendaring linear pressure is 10 ~ 50KN/m; Lining hanging amount is 22 ± 2g/m
2; The hanging amount of surface layer slurry and the summation of surface layer coating layer hanging amount are 50 ~ 54g/m
2;
(4) coating method adopts road, front three coating method, and total coating weight is 31g/m
2.
Above-mentioned steps is the step that the present invention improves, and all the other preparation process are prior art, repeat no more.
Compared with prior art, the present invention has following beneficial effect:
(1) lining of the present invention is that this type of wastepaper as raw material bulk is good, and air permeability is high, can improve the bulk of lining waste paper pulp with mechanical pulp raw material for main 40% old and useless newspaper of manufacturing paper with pulp; Sandwich layer is the waste and old corrugation boxboard of 60% mixed waste paper and 40%, can improve the bursting strength of sandwich layer waste paper pulp;
(2) the present invention is by adjustment wet end furnish, the long fibre of sandwich layer and prime cement is carried out to the making beating of appropriateness, on the basis ensureing light basis weight, improves the bursting strength of paper;
(3) raw materials used wide material sources in environment-friendly type cationic starch flocculant preparation process of the present invention, cheap, and its product by complete biodegradable, can be formed benign cycle, can be used as environmental protection flocculant of new generation and apply.
