A kind of maceration extract and its transparency paper of preparation and the method for quickly preparing transparency paper
Technical field
The invention belongs to transparency paper technical field, more particularly to a kind of maceration extract and its transparency paper of preparation with it is quick
The method for preparing transparency paper.
Background technology
Cellophane paper is a kind of speciality paper with excellent transparency, the common imitation parchment of in the market, glassine paper, tracing
Paper, Ge Laxin paper belong to cellophane paper.Cellophane paper with low-carbon environment-friendly, can be rolled up as a kind of emerging high-performance substrate
It is bent, can be the advantages of processing temperature be high, printability is good.Because having sustainable development, raw material to be easy to get and copy paper convenience, bio-compatible
Property and degradability, beneficial to volume to volume print the advantages, extensive use such as making, excellent optics, mechanics and barrier property
In fields such as packaging for foodstuff, map, peelable label paper, high-grade packaging, mountings.
The preparation method of current transparency paper mainly has following several:(1)Manufactured paper with pulp using the natural fiber of high beating degree and
Into.More than this method in the production of translucent drawing paper, the conventional method of current domestic production translucent drawing paper is the sulfate by bleaching
Wood pulp, is beaten by high viscosity, is then glued, then manufactures paper with pulp and form on long mesh paper making machine;(2)By the way that paper is impregnated into tree
In fat, mineral oil, varnish, natural gum and its mixture, and then the hole filled inside page makes paper become transparent;(3)Using
Chemical reagent dissolves the cellulosic sections of paper surface, and fiberfill fibers internal voids obtain transparency paper;(4)Using cellulose
Cellulose is completely dissolved, regenerated into transparent membrane by solvent;(5)Using scattered nanofibrils cellulose as base stock system
Standby cellophane paper.First method be applied to cellophane paper preparation of industrialization, but fiber height mashing and superpressure processing energy consumption compared with
It is high so that the cost of preparation is higher.And cellophane paper is prepared using infusion process, the method is simple and easy to apply, beneficial to large-scale production, research
Persons have also been made many research to this.For example:Li Hong et al. uses emulsion polymerization acrylic acid synthesizing resinae paper clarifier
Cellophane paper is prepared, but is directed to polymerisation, required raw material type is more, and the reaction time is longer, and it is prepared transparent
Paper transparency is relatively low, it is impossible to meet actual demand(The flat addition styrene of Li Hong, Li Xin is to synthesis Paper
Influence [J] Shaanxi Tech Univ's journals (natural science edition) of clarifier, 2007,25 (4): 1-5.).Ma Xiao widely collects use
Homemade clarifier prepares cellophane paper, but the transparent paper transparency prepared by him is relatively low, and after dipping under the bursting strength of paper
Drop is more, is unfavorable for application in practice(Ma Xiaobo GWT paper clarifier and its application study [D] Tianjin science and technology are big
Learn, 2013.).Foreign scholar Petrosky Linda M are using maleate, vinyl monomer and allyl compound composition
Clarifier prepares cellophane paper, but required dip time is longer, and needs to solidify in the presence of ultraviolet, and reaction condition is severe
Carve, be unfavorable for industrialized production(Petrosky L M. Transparentized medium and process for
making same: U.S. Patent 5,849,398[P]. 1998-12-15.).Meanwhile, researchers are to transparency paper
Other preparation methods have also carried out some researchs:Such as using cellulose solvent, homogeneous cellulose solution and ionic liquid system
Standby cellophane paper.But the technical process involved by above method is complex, and cost is higher, is unfavorable for large-scale production.
Therefore, a kind of transparency paper and its fast preparation method are developed, work is prepared for solving to exist in the prior art
Skill and program are relative complex, and preparation cost is higher, is difficult to realize industrialized technological deficiency, as those skilled in the art urgently
