The Rsearch Of Modifying Paper-tube Adhesive By Fillers

With the development of science and technology,The speed of making paper-tube is becoming more faster,Which puts forward new demands for paper-tube adhesive performance.But paper-tube adhesive exists evident shortcomings such as intial adhesive time long and rate of drying slow ,New it constrains the development of the paper-tube industry.It becomes necessary for the markets competition how to make high-qulity paper-tube adhesive in low cost ways,so this topic has great practical significance.This text has a foothold on the foundation of the modified paper-tube adhesive corpus resin,Broadly draw lessons from the relevant knowledge that the filler modifys gum, and carried on the beneficial trial, first, apply the general fillers modify paper-tube adhesive,and get a more reasonable formulation, then, and carry on improveing the place of the key filler shortage, then further modifying paper-tube adhesive with the property modification filler,adopt experiment and get the more ideal formulation.The experiments the enunciation.(1)The tentative experiment with general filler modifying paper-tube adhesive shows that: 38 of the modified polyvinylemuision(28.5%), 62 of the oxidized starch glue(20%) by the hydrogen peroxide,20 of aqueous bentonite solution (25%),10of polyacrylamide(10%), make the function conform to standard of the high-speed paper-tube adhesive and the cost of the gum will consumedly lower.But the function of the starch glue is not enough good, and will influence the quantity of mixture;The bentonite joins the modified polyvinylemuision to mix with the starch glue in the system, the stability is not enough ideal; while having the pressure to glue to connect the paper tube, the gum may leak ,It need the improvement.(2) The study of modification filler modifying the paper-tube adhesive show that: Improve the function of starch, can increase the quanlity of starch glue used in paper tube gum and further lowered the cost;adding a littile of functional filler in case of gum leaking and shortening intial adhesive time;adding the beetle,making it mixed with bentonites to form pipelines for water to permeate toward paper throug filler, Quicken the rate of dry as well as futher exaltation of stability;The best formulation:34 of the modified polyvinylemuision(28.5%),66 of the compound modified starch glue(20%),10 of functional filler(30%),25 of bentonite(25%), the pH adjusts to 8.50, joining just the right amount of assistance reagents; Its economic costs is 1330Yuan/t;Its index sign:The pH is 8.50,Non-volatile matter content idexs is...
