Abstract
The invention discloses a preparation method for a recycled paper stickies control agent. The recycled paper stickies control agent is obtained by carrying out graft copolymerization on Bentonite type attapulgite clay (Al2, Mg3) [Si4O10][OH]2.nH2, talcum powder Mg3(Si4O10) and polyacrylamide under a progressive action of an initiator and a cross-linking agent. The preparation method disclosed by the invention is simple in process, easy to prepare, low in cost and the quality of papers is promoted, the cost of paper products is reduced, and the environment is protected.
Description
Technical field
The present invention relates to regeneration paper stock stickies control agent is and in particular to a kind of preparation of regeneration paper stock stickies control agent
Method.
Background technology
In recent years, China's Paper Industry Development quickly, especially recycled writing paper oneself account for as many as paper products half of the country.But from waste paper
Import volume change on be not difficult to find out sicker be restriction recycled writing paper expanding production obstacle.Imported waste paper 30,070,000 in 2012
Ton, 29,230,000 tons of imported waste paper in 2013,1141.3 ten thousand tons of first half of the year imported waste paper in 2014, and price is descending, valency in 2014
Lattice drop 5.2% compared with the same period of last year.Lay the blame on its main cause: one is the impact paper machine operation of recycled writing paper sicker, forming net, scraper plate,
Paper industry is caused to break end as a result, fault power time is many on felt, pressure roller and drying section dryer scraper, production is affected；Two
It is due to Stickies deposit in the product, causes product spottiness, hole, drop bottom physical strength, affect product quality.
Content of the invention
The purpose of the present invention is: provides a kind of preparation method of regeneration paper stock stickies control agent, using this preparation method
The regeneration paper stock stickies control agent obtaining is used for recycled writing paper and produces, and improves into paper ash and divides, and improves keeping of wet end of machine system
Rate, also contributes to control, reduce sicker output, the quality of lifting paper simultaneously, reduces the cost of paper product, environmental protection, have
Manufacturing paper with pulp beneficial to page.
The technical solution of the present invention is: with bentonite type attapulgite clay ((al2, mg3) [si4o10] [oh] 2
Nh2o), Pulvis Talci and PAM gradually follow in initiator and cross-linking agent and are grafted under effect altogether suddenly, obtain stickies control agent；
It is characterized in that the preparation method of this stickies control agent comprises the following steps:
(1) preparation of bentonite type attapulgite clay liquid: press its quality in 1000g bentonite type attapulgite clay
20% adds sulphuric acid, expects 24h again；380 DEG C of temperature -- 400 DEG C of drying 1h；Be watered mass concentration 30% serosity；Serosity is placed in sand milling
It is ground to 1000--1250 mesh namely 10-13 μm in machine, obtain bentonite type attapulgite clay liquid, stand-by；
(2) preparation of Pulvis Talci mixed liquor: take Pulvis Talci 1000--1250 mesh 200g, plus PAM 6g, use quality
In concentration 5-40%naoh solution with become 50% serosity；While in and stirring while add initiator octadecanoid acid 1.5g and cross-linking agent n, n
Methylene bisacrylamide acyl ammonium, is heated up to 70 DEG C and stirs 1.5 hours, obtain Pulvis Talci mixed liquor, stand-by；Wherein, cross-linking agent n, n is sub-
The double acryloyl ammonium of methyl is the 1%---10% of PAM quality；
(3) regenerate the preparation of paper stock stickies control agent: take bentonite type attapulgite clay liquid after step (1) sand milling
50ml, takes step (2) Pulvis Talci mixed liquor 10ml, adds the br3cr of 3g aluminum sulfate and 1g, 10000 revs/min of mixed at high speed 7
Minute, paper stock stickies control agent must be regenerated.
The invention has the advantage that process is simple, prepare easily, with low cost, using PAM, octadecanoid acid in alkali
During catalytic polymerization, reaction generates the continuous items of insoluble polymer and the dispersion phase of bentonite type attapulgite clay, when with water
During mixing, continuous dependence stably adsorbs on electronegative Plant fiber c6h1005 by c00 and c00h group hydrophilic chromium atom,
(c18h36o) root of hydrophobic is made to form a water-resistance surface, thus producing water repelling property；Work in paper stock stickies control agent
With under, sicker is catalyzed, is controlled, and realizes sicker and is improved in paper stock production process, lifting paper quality, reduce
The cost of paper product, environmental protection, be conducive to manufacturing paper with pulp of page.
