Description
Technical field
It is a kind of starch composites the invention belongs to corn deep processing technology application field, the alternative starch of said composition
For in papermaking, improving the quality of paper product, production cost is reduced.
Background technology
Paper industry is the conventional industries of light industry, and the consumption and the level of production because of paper also represent a country and ground
Area's development of economic and culture is horizontal, and synchronized development situation is presented with national economy in paper industry.According to《Chinese paper chemicals industry city
Field research and investment forecasting analysis report》Data show, China's paper and production amount increase to from 30,500,000 tons of 2000
86,400,000 tons in 2010, increased between 10 years nearly twice, it has also become the big producer of world's papermaking first；Chinese paper product
Total quantity consumed is also increased with 18% speed, turns into second-biggest-in-the-world paper product country of consumption.As China's papermaking chemical product is in papermaking
Constantly being lifted using proportion in industry, it is contemplated that following papermaking chemical product average growth rate per annum is up to 9% or so；Made by 2018
Paper chemicals market scale will be more than 60,000,000,000.
Starch for paper-making accounts for the 3rd of papermaking chemical product.Global paper industry year uses about 5,000,000 tons of starch, accounts for paper
With the 1.5% of cardboard total amount.Analyzed from raw material mix, the 67% of world's starch for paper-making raw material is cornstarch, is secondly
Cassava and farina.U.S.'s paper industry starch, 95% is cornstarch, and more uses modified starch, and state
Interior major part cornstarch and tapioca, modified starch dosage is less than 35%.
Cornstarch wide material sources, price is low, but its viscosity is low, and additional proportion is high；Cassava and farina viscosity are high,
Dosage can be reduced, but its price is high；Converted starch is mostly wet production, and production technology length, investment is high, therefore cost price is more
Height, it is used for high-end paper.Domestic paper industry is all matched somebody with somebody to reduce cost in the market price with various starch to convert use
Side, Replacement procedure, difficulty is brought to production control.
Paper industry is also one and closely bound up important industry is built with social civilization, with attention of the country to environmental protection
With increasing law enforcement dynamics, paper industry the biggest problem is environmental issue, wherein paper waste caused by slurrying, and pollution is the tightest
Weight, it is in dark brown that waste water is discharged during pulp washing, and pollutant concentration is very high, and BOD is up to 5-40g/L, containing a large amount of fibers, inorganic salts and
Pigment；The waste water of bleaching process discharge contains substantial amounts of acid-base material；The waste water of paper machine discharge, containing a large amount of fibers and in life
The filler and sizing material added during production.
The market prospects that to sum up paper chemicals industry develops at home are optimistic, how to reduce production cost, improve product
Quality, it will be current each main brainstorm subject of paper industry to reduce pollution.
Sodium tripolyphosphate and starch molecule at temperature and alkalescence condition can hair esterification, urea plays catalysis and makees
With the hydrogen on the hydroxyl of starch chain is substituted by phosphate groups, i.e., small group is substituted by macoradical, produces steric hindrance, hinders
Intermolecular adhesion, while space increases, crystal region is destroyed, and water is easier to penetrate into starch molecule, starch is existed
Certain temperature and the lower easily gelatinization of water effect.And reaction efficiency is higher when pH value is 7.5 or so, while the growing amount of carbonyl
Relatively more, carboxyl is stronger to the adhesion of fiber substance, and carboxyl is in the basic conditions anionic property, can also be adsorbed
Paper pulp cationic.
Polyvinyl alcohol, which is dissolved in after water, forms water-polyvinyl alcohol complex absorption on starch particle surface, by small of starch
Grain shielding is got up, and plays buffer action the hydroxyl starch granules, assigns dispersion stability, polyvinyl alcohol can also with it is straight
Chain Starch formation helical form compound, plays stabilization.
The content of the invention
The present invention provides a kind of starch composites being used in paper industry, it is therefore an objective to provides a kind of viscosity height, gelatinization temperature
The excellent product of low, paste liquid excellent transparency, adhesive performance is spent, for substituting starch in paper industry, raw material usage amount can be reduced,
Steam consumption is reduced, paper product quality is improved, mitigates blowdown, so as to reduce production cost, environmental protection.
The present invention adopts the technical scheme that, made of the raw material of following parts by weight：
96 parts of cornstarch, 4 parts of waxy corn starch are made into blending starch, so that starch is blended as radix, sodium tripolyphosphate
Account for blending starch 4.0-6.0%, urea accounts for that 4.0-5.0%, sodium carbonate 1.0 ‰, complexing agent account for 3.0-5.0 ‰, stabilizer accounts for
0.8-1.0%.
Above-mentioned raw materials are well mixed at room temperature, as starch composites.
The method have the advantages that gelatinization point is low, reduce steam consumption, increase speed, improve production efficiency；Reaction control is high
Dosage can be reduced to substitute cornstarch or substitute tapioca completely, reduce production cost, it is same to enter also reduce because of Poor cohesion
The scrappage of cardboard is caused, improves the yield rate of cardboard；Paste liquid stability is good, and viscosity is unchanged in storing process, production technology
It is stable；It is good to fiber adhesive performance, good with other auxiliary agent compatibilities, reduce blowdown, environmental protection.
