Abstract
The invention discloses paper tube base paper which is prepared with fiber pulp through a paper making method; the tightness of the paper tube base paper is 0.8g/cm<3> to 0.88g/cm<3>. The invention also discloses a method for preparing paper tube base paper with fiber pulp serving as the raw material, which comprises the following steps: pulping, auxiliary material adding, mesh adding and dewatering, compression, drying and press finishing; the dry step comprises a semi-wet glazing sub-step; the semi-wet glazing sub-step is a step of pressing wet paper pages before the water content of the wet paper pages reaches the water content required by finished paper pages. The method not only has small pulping pollution load, low cost, high tightness of base paper and high fiber bonding strength; and the produced paper tube is applicable under the conditions of high speed and high strength or high speed and high pressure resistance.
Description
Technical field
The present invention relates to the paper tube base paper technical field, the invention still further relates to the manufacture method of paper tube base paper.
Background technology
Along with China's rapid economy development, refill, paper tube product are low with its cost, light weight, easily reclaim, advantage such as nuisanceless, already obtained widespread usage at paper-making industry, packing business, textile chemical fiber.It both can be used as the inner core of various roll webs and cardboard, also can be used as used textile bobbins such as synthetic thread, terylene, polypropylene fibre, spandex, progressively replaced conic bobbin in particular for the paper tube of textile industry.When people paid attention to refill, paper tube quality, also great changes will take place to the theory of its used body paper specification requirement.
Textile bobbin normally uses under high-speed high-strength or the high measuring body condition of high speed, therefore concerning the body paper of making textile bobbin, just has higher requirement.The paper tightness is the important indicator that influences paper performance, and the factor that influences the paper tightness has a lot, and for example the rugosity of fiber it has been generally acknowledged that, the rugosity of fiber is big more, and the tightness of paper is more little; For another example, manufacture paper with pulp squeezing and press polish in the process.But existing paper tube base paper under the condition of general fibre coarseness, is optimum with the condition setting of the influential tightness of institute of the process of manufacturing paper with pulp, and its tightness also can only be at 0.78g/cm
3Below, and owing to amplified the condition that influences tightness, it is inhomogeneous to make body paper inhale glue in becoming the pipe process, is easy to generate flounce problem and booster problem.
On the other hand, on production technology, external joining according to sufficient KP commercial wood pulp usually copies, add step, online dehydration, squeezing step, drying steps and press polish step by making beating step, auxiliary material, make paper tube base paper, not only cost height, and slurrying pollutional load is big, and the environmental protection policy of the energy-saving and emission-reduction of carrying out with China is incompatible.
Summary of the invention
Technical problem to be solved by this invention is: a kind of paper tube base paper is provided, and this paper tube base paper tightness height, fiber bond strength height, the paper tube of making are adapted at using under high-speed high-strength or the high measuring body condition of high speed.
Another technical problem to be solved by this invention is: a kind of method of making paper tube base paper is provided, not only the slurrying pollutional load is little for this method, cost is low, and the tightness height of body paper, fiber bond strength height, the paper tube of producing thus are adapted at using under high-speed high-strength or the high measuring body condition of high speed.
For solving the problems of the technologies described above, technical scheme of the present invention is: paper tube base paper, form through copying the manufacturing of paper method with fibre stuff, and the tightness of this paper tube base paper is 0.8～0.88g/cm
3
Make the method for paper tube base paper, with the fibre stuff is raw material, comprise that making beating step, auxiliary material add step, online dehydration, squeezing step, drying steps and press polish step, in described drying steps, comprise one and half moist calenderings step by step, described half moist calendering is step by step before the moisture content of l Water Paper page or leaf reaches the desired moisture content of finished product page, the step that the l Water Paper page or leaf is exerted pressure.
Wherein, described half moist calendering is step by step when the moisture content of l Water Paper page or leaf reaches 20～25wt%, the l Water Paper page or leaf is applied the step of 30～80Kg/cm linear pressure.
Wherein, described fibre stuff is the secondary stock slurry.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: generally, exerting pressure of wet page or leaf paper generally all carried out in squeezing step and press polish step, the main effect of exerting pressure in the squeezing step is the moisture content of removing in the l Water Paper page or leaf, improves mass dryness fraction; And the effect of exerting pressure in the press polish step is smoothness, glossiness and the thickness evenness that improves paper.After the squeezing step, still contain the moisture content of 50～60wt% in the l Water Paper page or leaf, the effect of drying steps is exactly with the water evaporates in the l Water Paper page or leaf, and moisture content is reduced to about 7wt%.Because the present invention also comprises one and half moist calenderings step by step in described drying steps, by implementing such step, moisture content at the l Water Paper page or leaf reaches under the condition of 20～25wt%, the l Water Paper page or leaf is exerted pressure, its line pressure is 30～80kg/cm, and then proceed drying steps, reach the regulation requirement until moisture content.With respect to the press polish behind the drying steps, it not only can successfully finish applying glue, and can just can obtain bigger tightness by less linear pressure, has improved the fiber bond strength, and the banner thickness difference further dwindles.And before the present invention, for the person of ordinary skill of the art, in order to obtain high tightness, general by improving the raw material beating degree, or improve the commercial wood pulp ratio, or strengthen the press section linear pressure, can't imagine step by step and in drying steps, increase by one and half moist calenderings.Test data shows that by implementing the present invention, the tightness of paper tube base paper can reach 0.8～0.88g/cm
3, improved the performance of paper tube base paper greatly.
Because when making paper tube base paper, the fibre stuff of use is the secondary stock slurry, the slurrying pollutional load is little, the whitewater closure circulation, and no chlorine is nontoxic, does not contain brightening agent, after using up, recycles fully paper tube base paper, and be a kind of environment-friendly products.By implementing such method, can reduce production costs greatly, reduce environmental pollution, improve competitiveness of product.
