Abstract
The invention provides a clay coated kraft back material and a preparation method of a clay coated kraft back. The clay coated kraft back material comprises 3%-50% of paper pulp and 50%-97% of a kraft material. The clay coated kraft back provided by the invention has the beneficial effect of low papermaking cost, is capable of keeping good printability of a white manila board, and is also capable of providing paper grades, which are relatively high in strength indexes (burst index and ring crush index), and of which the value is between the value of the white manila board and the value of the coated kraft by adjusting a core prime paper pulp material, so as to adapt to the requirements of groups with a relatively large range and special use.
Description
Technical field
The present invention relates to the technical field of papermaking, refer more particularly to a kind of coating ox coated duplex board with white back raw material and coating ox coated duplex board with white back preparation method.
Background technology
The boundary between coated duplex board with grey back and coating ox card has clearly been divided in traditional coated board classification, coated duplex board with grey back is more prone to middle and high end printing packaging material, be mainly used in embodying the good printability of paper to provide perfect printed matter, coated craft paper is then mainly used in boxboard vermicelli, and the physical index therefore for paper requires harsher.But on the segmenting market, vacuum vacancy is then belonged to for high printability and higher building reason intensity coating paperboard.Therefore study and a kind ofly can either meet good print adaptive and have the paper kind that can provide certain physical strength imperative with the demand meeting terminal client.
Summary of the invention
The object of this invention is to provide a kind of coating ox coated duplex board with white back raw material, to solve the above-mentioned deficiency of prior art.
The object of the invention is to be achieved through the following technical solutions:
The invention provides a kind of coating ox coated duplex board with white back raw material, this coating ox coated duplex board with white back raw material comprises: the paper pulp of 3% ~ 50% and 50% ~ 97% N of card raw material.
Preferably, described paper pulp comprises core layer raw material and bottom raw material.
Preferably, described core layer raw material comprise 10% No. 2 imported from America waste paper or No. 3 European imported waste papers, 40% No. 4 European imported waste papers or No. 5 European imported waste papers, 10% C level domestic waste paper or state's Waste Commission goods, and the domestic category-A boxboard corrugated paper domestic waste paper of 40% or domestic category-B boxboard corrugated paper domestic waste paper.
Preferably, described bottom raw material is No. 8 imported from America waste paper or domestic category-B boxboard corrugated paper domestic waste paper.
Present invention also offers a kind of preparation method being coated with ox coated duplex board with white back, the method comprises the following steps:
The paper pulp of 3% ~ 50% and 50% ~ 97% N of card raw material are passed through press section press;
Drying is carried out to the paper pulp after squeezing;
By sizing applicator, applying glue is carried out to dried paper pulp;
Drying is carried out to the paper pulp after applying glue and forms coating ox coated duplex board with white back.
Preferably, describedly by sizing applicator, applying glue is carried out to dried paper pulp and is specially:
Be 1.1 ± 0.3g/m at front surface resin added
2, back side resin added is 1.5 ± 0.3g/m
2, back of the body painting amount is 0.9 ± 0.3g/m
2.
Beneficial effect of the present invention is: coating ox coated duplex board with white back provided by the invention causes low, the printability that coated duplex board with grey back is good can either be kept, higher intensity index (resistance to broken, ring pressure) can be provided again by adjustment core prime cement raw material, be worth the paper kind between coated duplex board with grey back and coating ox card, thus to adapt to demand that is wider and Special use colony.
Detailed description of the invention
In order to reduce the energy resource consumption of coating ox coated duplex board with white back raw material, embodiments provide a kind of coating ox coated duplex board with white back raw material.In the inventive solutions, by adopting paper pulp and Niu Ka raw material to make coating ox coated duplex board with white back, thus reaching the object improving coating ox coated duplex board with white back applicability, with specific embodiment, technical scheme of the present invention being described below.
Embodiments provide a kind of coating ox coated duplex board with white back raw material, this coating ox coated duplex board with white back raw material comprises paper pulp and 50% ~ 97% N of card raw material of 3% ~ 50%.
Preferably, described paper pulp comprises core layer raw material and bottom raw material.
Preferably, described core layer raw material comprise 10% No. 2 imported from America waste paper or No. 3 European imported waste papers, 40% No. 4 European imported waste papers or No. 5 European imported waste papers, 10% C level domestic waste paper or state's Waste Commission goods, and the domestic category-A boxboard corrugated paper domestic waste paper of 40% or domestic category-B boxboard corrugated paper domestic waste paper.
Preferably, described bottom raw material is No. 8 imported from America waste paper or domestic category-B boxboard corrugated paper domestic waste paper.
With specific embodiment, the present invention will be described below:
Embodiment 1
This coating ox coated duplex board with white back raw material comprises the paper pulp of 50% and the ox card raw material of 50%.The coating ox coated duplex board with white back produced can either keep the printability that coated duplex board with grey back is good, can provide higher intensity index (resistance to broken, ring pressure) again by adjustment core prime cement raw material.
Embodiment 2
This coating ox coated duplex board with white back raw material comprises the paper pulp of 30% and the ox card raw material of 70%.The coating ox coated duplex board with white back produced can either keep the printability that coated duplex board with grey back is good, can provide higher intensity index (resistance to broken, ring pressure) again by adjustment core prime cement raw material.
Embodiment 3
This coating ox coated duplex board with white back raw material comprises the paper pulp of 20% and the ox card raw material of 80%.The coating ox coated duplex board with white back produced can either keep the printability that coated duplex board with grey back is good, can provide higher intensity index (resistance to broken, ring pressure) again by adjustment core prime cement raw material.
