Description
Technical field
The present invention relates to pulp technology for making paper, particularly relate to a kind of dustless protective paper paper technology of liquid-crystalline glasses with high-antistatic performance.
Background technology
Liquid-crystalline glasses is widely used in electronic enterprises as base material, owing to liquid-crystalline glasses surface is fragile, is easily scratched, easily by static interference, therefore liquid-crystalline glasses must be packed and protect in production operation and transportation. Current people are used mostly dust-free paper, and liquid-crystalline glasses is spaced apart, to play protection and to eliminate the effect of electrostatic. The dustless protective paper of traditional liquid crystal glass mainly adopts the method for spraying antistatic additive to give its antistatic behaviour, and antistatic property is poor and can not be lasting.
The increasingly high-end precise treatment of liquid crystal glass substrate, more sensitive to electrostatic in recent years, simultaneously when production operation, owing to electrostatic interaction firmly holds between paper, has a strong impact on production, and this is also the difficult problem always perplexing manufacturer. Therefore a kind of dust-free paper with higher antistatic performance of urgent needs. If utilizing the method increasing antistatic additive consumption to improve paper antistatic property, then influencing whether other performance indications of paper, as flexibility and bulkiness reduce, paper loses intensity.
How when not damaging paper performance index, the antistatic property promoting the dustless protective paper of liquid-crystalline glasses is the important topic of the dustless protective paper research field of liquid-crystalline glasses.
Summary of the invention
The invention provides a kind of simple, method of being effectively improved dust-free paper antistatic property.
The present invention is achieved by the following technical solution.
First at Time of Fluff Slurry a certain amount of antistatic additive of pulpboard surface spraying, antistatic additive consumption controls at the relative oven dry stock of 0.1%-0.5%() in scope, then pulverizer is utilized to be pulverized by pulpboard, fiber disperser is utilized to be disperseed by fiber, scattered be mixed into the relative oven dry stock of 0.8%-1.5%(simultaneously) carbon fiber, carbon fiber length is 3-6mm, resistivity is 103-105�� cm, after mix homogeneously, utilize air jet system, at the ply of paper that antistatic polyester carbon web forming is thin, after 135-145 DEG C and 175-185 DEG C of two sections of pre-hot pressing, paper web is respectively fed to upper and lower spraying colloid system and dries, glue spraying concentration controls within the scope of 11%-13%, then being delivered in curing box by paper web again and latex is carried out ripening, curing temperature controls at 175-185 DEG C, finally paper web is carried out ornamenting, press polish, batches, rewinding, cuts and pack.
In the technique of the present invention, by using the 100% needle leaved wood napped pulp fibres of pure sulphite, reach to improve slurry purity, strengthen paper strength, reduce the purpose of powder amount.
In the technique of the present invention, by spray antistatic additive, it is prevented that in production process fiber due to electrostatic floc sedimentation, it is ensured that paper-forming evenness;Wherein, the antistatic additive adopted is a kind of alkyl phosphoric acid esters antistatic additive.
In the technique of the present invention, by strictly controlling length and the addition of the carbon fiber of different resistivity, when not affecting other indexs, it is greatly improved antistatic effect and permanent effective.
In the technique of the present invention, by two sections of hot pressing, making paper web tightness increase, fiber bonds increases, and has certain initial strength.
In the technique of the present invention, by using dust-free paper special-purpose latex EN-429, and strictly controlling upper gum concentration, make page not stratified, simultaneously because be mixed with a small amount of drying strengthening agent, wet strength agent, penetrating agent, dust-free paper has good dry and wet intensity.
The invention has the beneficial effects as follows: one, due to the fact that and be mixed into a certain amount of carbon fiber, decrease the electrostatic owing to fibre frictoin produces, alleviate fiber and unite phenomenon, improve formation of sheet. Two, when other performance indications are not affected by affecting, substantially increase into the antistatic property of paper, carbon fiber belongs to permanent antistatic agent simultaneously, it is to avoid the situation that traditional dust-free paper in use antistatic property gradually loses.
