Abstract

The present invention relates to a kraft jackcard white board paper. It is characterized by that it is made up by using box board paper and spool paper as raw material. The box board paper and spool paper are the papers made up by using waste papers through beating and paper-making process. The box board paper and spool paper are fixedly connected into one body by means of adhesive, and the external surface of said spool paper is coated with coating layer. Said invention blongs to a secondary fiber paper-making reutilization technique, so that its cost is low and it can save lots of wood material.

Description

A kind of ox card white board

Technical field

The present invention relates to a kind of ox card white board.

Background technology

Ox card white board is an electronic device carrier paper.At present, the ox card white board that the electronic device manufacturer of China is used all is by U.S.'s import.This kind paper is to be raw pulp with timber, is made as finished paper with the method that is coated with in the machine, promptly directly makes ox card white board in the paper mill with wood pulp, has to consume timber resources, drawback that the expense expenditure is big.

Summary of the invention

The purpose of this invention is to provide the ox card white board that a kind of boxboard that is made into waste paper and cop tube paper are main raw material.

For the purpose that realizes inventing, the ox card white board that is provided, comprise that selecting boxboard and two kinds of finished products of cop tube paper for use is raw material paper, it is characterized in that boxboard and cop tube paper all are with the waste paper latter made paper of pulling an oar, sticking with glue agent on a face of boxboard fixes as one cop tube paper, be coated with dope layer on the outer surface of cop tube paper, described adhesive is that polyvinyl alcohol and starch are added to the water, under stirring condition, in water, feed temperature and be higher than 100 ℃ steam, continue after 150 minutes-180 minutes, make with being not less than the filtration of 100 purposes sieve again, three's proportioning is 10 parts of polyvinyl alcohol by weight, 7 parts-8 parts of starch, 120 parts-130 parts in water, the used coating of dope layer are to be 84 orders-95 purpose china clay with 500 parts of-700 parts of granularities by weight, 0.5-2 parts of bactericide 2-methyl-4-isothiazoline-3-ketone of part or 5-chloro-2-methyl-4-isothiazoline-3-ketone, 4 parts of-5 parts of dispersant Sodium Polyacrylates, 1 part of-2 parts of neutralizer NaOH, 1 part of-1.5 parts of fluorescent whitening agent VBL, 10 parts of-15 parts of adhesive polyethylenes pure and mild 60 parts-90 parts by butadiene, the styrene-butadiene emulsion that styrene is synthetic, 20 parts of-30 parts of lubricant (C that add lustre to ₁₇H ₃₅COO) ₂Ca joins in 300 parts-400 parts the water, feeds temperature and be higher than 100 ℃ steam under stirring condition in water, continues after 120 minutes-140 minutes, makes with being not less than the filtration of 80 purposes sieve again.

Above-mentioned dope layer is that the coating that will make forms through the continuous painting process of twice, the first road painting process is that air knife is coated with, be coating to be coated on the outer surface of cop tube paper for the formed air knife of the air-flow of 9.3Pa with boosting of blowing out of blower fan, coating weight is every square metre 40 gram-50 grams, enter the second road painting process after the oven dry, the second road painting process is that scraper is coated with, be to be under 30 kilograms every square centimeter the condition coating to be coated on being coated with on the face that air knife is coated with at pressure with mechanical doctor, coating weight is every square metre 15 gram-20 grams, oven dry back press polish.

Ox card white board provided by the present invention; owing to be to be main raw material with the finished paper-boxboard and the cop tube paper that are made into after the waste paper making beating with two kinds; belong to the application once more of secondary fiber papermaking; the adhesive of being prepared and the coating of dope layer also all are the industrial chemicals that is easy to get; therefore not only the cost of product is low; and saving timber, help protecting forest resources and ecological environment, not only benefit the nation but also favorable to the people.
