Abstract
The invention discloses a kind of preparation methods of lower shrinkage secondary stock neutral sizing.The preparation method of lower shrinkage secondary stock neutral sizing of the present invention is by using unique making raw material proportioning, slurry when paper machine pulping method, to solve the problems, such as existing do not have good lamination or gluing function by the neutral sizing of primary raw material of waste paper, the method of the present invention can improve the shrinkage of paper, smoothness and intensity, the lower shrinkage secondary stock neutral sizing shrinkage produced reaches within 3mm, reach 40S or more at paper positive and negative smoothness, paper tensile strength MD >=2.8KN/M, paper tensile strength CD >=1.3KN/M, and have good lamination or gluing function, it is suitble to promote and apply.
Description
Technical field
The present invention relates to paper technologies, and in particular to a kind of preparation method of lower shrinkage secondary stock neutral sizing.
Technical background
At present in regenerated papermaking industry, do not have good lamination generally using the neutral sizing that waste paper is main material production
Or gluing function, purposes range is smaller, while the domestic lower shrinkage secondary stock neutral sizing production based on wastepaper as raw material
Enterprise can not provide lamination or product that gluing effect is stablized is to packaging due to immature etc. in production Technology
Printing enterprise causes the lower shrinkage neutral sizing product of Packaging and Printing Enterprises demand to rely primarily on whole wood pulp product or import production
Product improve cost.
Invention content
It is good it is an object of the invention to solve not having generally using waste paper as the neutral sizing of main material production at present
The problem of lamination or gluing function, provides a kind of lower shrinkage secondary stock neutral sizing having good lamination or gluing function
Preparation method.
Above-mentioned purpose of the present invention is achieved by the following technical programs：
A kind of preparation method of lower shrinkage secondary stock neutral sizing includes the following steps：
（1）Raw material is the high whiteness high-cleanness, high Deinking Pulp that Mixed Office WasteMOW is produced；Mixed Office WasteMOW raw material line
Adapted 30%37# U.S.s are useless, 20% Japan's 3# waste paper and 50% state give up high-quality little Hua and great Hua；
（2）Paper machine is manufactured paper with pulp wet end furnish：15% sulphate chemical bleaching mixing wood pulp, 75% deinking of MOW slurry and
10% waste stuff；Wherein, the sulphate chemical bleaching mixing wood pulp is the long fine wood pulp of 50% sulphate chemical bleaching and 50% chemistry
Bleach the mixing of thermomechanical wood pulp；
（3）Paper machine pulping method：Screen cloth jet-wire ratio is less than 65 meters, and product moisture norm controlling is 5.0 in production process
±0.5%。
Above-mentioned steps are the step of present invention improves, remaining preparation process is the prior art, is repeated no more.
Compared with prior art, the present invention has the advantages that：
（1）In common secondary stock wood-free paper raw material proportioning, 37# U.S.s give up and the proportional quantity of Japan 3# is within 40%, this hair
Bright raw material proportioning and traditional difference, the useless proportioning with Japan 3# of 37# U.S.s is improved, can improve the contraction of paper in this way
Property, flatness and smoothness；
（2）Common secondary stock wood-free paper does not use sulphate chemical bleached wood pulp, only the change of simple addition 5 ~ 10%
Bleaching thermomechanical wood pulp is learned, is not furnished with the long fine wood pulp of sulphate chemical bleaching, the present invention is long fine using sulphate chemical bleaching
The obtained mixing wood pulp of wood pulp and the short fine mix and match of machinery, contributes to the intensity and smoothness that improve paper；
（3）Common secondary stock wood-free paper screen cloth jet-wire ratio is 70 meters or more, and the present invention is by net Transmission Ratio Control 65
Rice is hereinafter, can improve the shrinkage after paper making；
（4）Common secondary stock wood-free paper product moisture is 6.0 ± 1.0%, and the present invention controls moisture 5.0 ± 0.5%,
It may insure the intensity and deflection of paper；
（5）The method of the present invention can improve the shrinkage, smoothness and intensity of paper, the lower shrinkage secondary stock produced
Neutral sizing shrinkage reaches within 3mm, reaches 40S or more, paper tensile strength MD >=2.8KN/ at paper positive and negative smoothness
M, paper tensile strength CD >=1.3KN/M, and have good lamination or gluing function.
Specific implementation mode
With reference to embodiment, the present invention is further elaborated.But embodiment is not the present invention any type of
It limits.
