Description
Technical field
The present invention relates to the fine ring in a kind of inorganic ore deposit for papermaking and press enhancing Cypres and preparation method thereof.
Background technology
At present domestic paper industry is for reducing production costs, and large multiplex waste paper is produced high-strength corrugated paper, but the severeest problem that faces is that ring crush intensity is low, does not reach client's requirement.For seeking solution, most of enterprise that produces high-strength corrugated paper has adopted the technology of the top sizing from external introduction in 2004 to solving this difficult problem.But present result is barely satisfactory.In recent years, industry was done a lot of technological innovations, comprised that attempting adding PVA etc. plays and increase the effect that ring is pressed in the top sizing process, although ring is pressed with certain raising, the production cost that exceeds allows again enterprise hang back.Thereby a kind ofly can improve ring crush intensity in the urgent need to finding in industry, and the technology that reduces production costs again or product.
Summary of the invention
The present invention, by adopting a part of surface sizing starch of the fine replacement in inorganic ore deposit, has not only improved the ring crush intensity of corrugated paper, has also reduced the papermaking cost.
The invention provides the fine ring in a kind of inorganic ore deposit for papermaking and press the enhancing Cypres, described sizing agent is comprised of surface sizing starch and inorganic ore deposit fibre, described inorganic ore deposit fibre is a kind of in grandidierite fibre, modified grammite, wollastonite, and the percentage that described inorganic ore deposit fibre accounts for the sizing agent quality is 5～40%;
Described grandidierite fibre is comprised of following component in mass ratio:
Described modified grammite is that its activation index is greater than 85% with silane coupler or stearic acid modified wollastonite.
The modifying process of the above-mentioned modified grammite of the present invention, for wollastonite is joined in high-speed mixer, adds modifier while stirring, mixes 20min, and described wollastonite and modifier mass ratio are 100:1.2, and described modifier is silane coupler or stearic acid.
To jiggle greatly to modified grammite moistening in order modified grammite is joined in distilled water in the ratio of 1g/25ml for the above-mentioned activation index assay method of the present invention, and ultrasonic 3～5min, after standing 24h filter the modified grammite of sedimentation, and drying, weigh; Deduct sedimentation modified grammite quality with the modified grammite gross mass and obtain floating modified grammite quality, according to formula (1), calculate activation index:
H=m
f/m
o×100% （1）
In formula (1): H is activation index (%), and mf is floating modified grammite quality (g), and mo is modified grammite gross mass (g).
The present invention adopts a part of surface sizing starch of the fine replacement in inorganic ore deposit, makes the ring crush intensity of corrugated paper improve 73.2～98.7%; Make the tensile index of art paper improve 1.9～8.5%, make the folding strength of art paper improve 4.3～45.3%, the papermaking cost has also reduced at least 10 yuan/tons.
The mass percent that inorganic ore deposit of the present invention fibre accounts for sizing agent is preferably 20～30%.
The present invention's purpose on the other hand is to provide a kind of preparation method of sizing agent, described preparation method is for to be made into mass concentration after mixing with surface sizing starch be 7～9% the aqueous solution with inorganic ore deposit is fine, be warming up to 80～100 ℃ after stirring, gelatinization 27～33min, be cooled to 55～65 ℃;
The mass percent that described inorganic ore deposit fibre accounts for sizing agent is 5～40%.
The purpose of another aspect of the invention is to provide the fine ring pressure in the described inorganic ore deposit of the invention described above to strengthen the application of Cypres in papermaking, presses the enhancing Cypres to be coated on body paper on the fine ring in inorganic ore deposit, and the control coating weight is 5.5～6.5g/m
