Description

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 and quickly The method for preparing transparency paper.
Background technique
Cellophane paper is a kind of speciality paper with excellent transparency, in the market common imitation parchment, glassine paper, tracing Paper, Ge Laxin paper belong to cellophane paper.Cellophane paper has low-carbon environment-friendly, can roll up as a kind of emerging high-performance substrate The advantages that bent, processable temperature is high, printability is good.Because having sustainable development, raw material to be easy to get and copy paper convenience, bio-compatible Property and degradability, conducive to the advantages such as roll-to-roll printing production, excellent optics, mechanics and barrier property, be widely applied In fields such as food packaging, map, peelable label paper, high-grade packaging, mountings.
At present transparency paper preparation method mainly include the following types: (1) using high beating degree natural fiber manufacture paper with pulp and At.This method is mostly used in the production of translucent drawing paper, and the conventional method of domestic production translucent drawing paper at present is the sulfate by bleaching Wood pulp is beaten by high viscosity, is then glued, then is manufactured paper with pulp on long mesh paper making machine；(2) by the way that paper is impregnated into tree In rouge, mineral oil, varnish, natural gum and its mixture, and then the hole filled inside page makes paper become transparent；(3) it uses Chemical reagent dissolves the cellulosic sections of paper surface, and fiberfill fibers internal voids obtain transparency paper；(4) cellulose is used Cellulose is completely dissolved, regenerates into transparent membrane by solvent；(5) using the nanofibrils cellulose of dispersion 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 Height, so that the higher cost of preparation.And cellophane paper is prepared using infusion process, the method is simple and easy, is conducive to large-scale production, research Persons this have also been made many researchs.Such as: Li Hong et al. uses emulsion polymerization acrylic acid synthesizing resinae paper clarifier Cellophane paper is prepared, but is directed to polymerization reaction, required raw material type is more, and the reaction time is longer, and prepared transparent Paper transparency is lower, and being unable to satisfy actual demand, (Li Hong, Li Xinping add styrene to synthesis Paper Influence [J] Shaanxi Tech Univ's journal (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 lower, and after dipping under the bursting strength of paper Drop more, (Ma Xiaobo GWT paper clarifier and its Tianjin application study [D] science and technology are big for the application for being unfavorable in practice It learns, 2013.).Foreign scholar Petrosky Linda M is using maleate, vinyl monomer and allyl compound composition Clarifier prepares cellophane paper, but required dip time is longer, and needs to solidify under the action of ultraviolet light, and reaction condition is severe It carves, is unfavorable for industrialized production (Petrosky L M. Transparentized medium and process for 5,849,398 [P] 1998-12-15. of making same:U.S. Patent).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 technical process involved in above method is complex, and higher cost is unfavorable for large-scale production.
Therefore, a kind of transparency paper and its fast preparation method are developed, preparation work exists in the prior art for solving Skill and program are relative complex, and preparation cost is higher, are not easy to realize industrialized technological deficiency, become those skilled in the art urgently It solves the problems, such as.
