Abstract
The invention relates to a papermaking sizing starch substitute as well as a preparation method and application thereof. The papermaking sizing starch substitute comprises the following raw materials in parts by weight: 20-40 parts of maltodextrin, 20-40 parts of a compound inorganic mineral fiber, 20-50 parts of ferrous sulfate, 2-5 parts of aluminum sulfate, 2-5 parts of boric acid and 1-3 parts of a thickening agent, wherein the compound inorganic mineral fiber is a combination of at least two of a wollastonite fiber, a sepiolite fiber and a quartz fiber. The substitute disclosed by the invention can completely replace sizing starch for surface sizing, is low in cost and has a good sizing effect; on the premise of completely replacing the sizing starch with the substitute for surface sizing, the water resistance and the annular pressure index of paper can be improved, and the problem that paper gets damp in summer can be effectively solved.
Description
Technical field
The present invention relates to a kind of surface of solids sizing agent and its preparation method and application.
Background technology
Along with the fast development of paper industry, secondary stock has become the main source of China's paper making pulp.This measure can solve the scarcity shortage of paper pulp, but in the secondary stock of recycling, regenerated fiber shortens, and larger for the quality influence of paper, ring crush intensity reduces, and does not reach client's requirement.In recent years, industry was done a lot of technological innovations, comprised that attempt adding PVA etc. plays and increase the effect that ring is pressed in top sizing process, although ring is pressed and improved, the production cost You Rang enterprise exceeding hangs back, and summer, paper Moisture Regain was obvious.Therefore, paper industry is in the urgent need to a kind of with low cost and sizing efficiency good, and can solve the get damp summer novel surface sizing agent product of problem of paper.
So far, all top sizings all need to use a large amount of size-press starch, and along with the impact of external and domestic market, starch price constantly promotes, how to use a kind of cheaply, can substituted starch carrying out top sizing and have good sizing efficiency be an emphasis of paper making additive industry research.
CN 103628355A discloses a kind of paper grade (stock) surface of solids sizing agent, and its component and weight fraction are than as follows: ferrous sulfate 78-90 part; Aluminum sulfate 5-20 part; Maltodextrin 1-5 part; Sodium sulphate 2-8 part.This sizing agent can replace 30% amount of starch, and WATER RESISTANCE is 25g/m
2, ring crush intensity index is 8.0n.m
2/ g.Although the disclosed sizing agent cost of this patent is compared starch, reduce, it only can partly substitute starch, and therefore, paper-making sizing cost is still very high.In addition, after this sizing agent Substitute For Partial starch applying glue, still can not solve the paper problem of getting damp summer.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of size-press starch that can replace completely for the paper-making sizing surface substituting agent of paper and/or paperboard surface applying glue, and this substituting agent is with low cost, and sizing efficiency is good, and can solve the paper problem of getting damp summer.
The present invention provides preparation method and application's method of a kind of paper-making sizing surface substituting agent simultaneously.
For overcoming the above problems, a kind of technical scheme that the present invention takes is as follows:
The agent of paper-making sizing starch in replace, in weight portion, the composition of raw materials of this paper-making sizing starch in replace agent is as follows:
Described composite inorganic mineral fibres is the combination of at least two kinds in wollastonite fibre, sea bag mineral wool and quartz fiber.
Preferably, the composition of raw materials of described paper-making sizing starch in replace agent is as follows:
Particularly, described composite inorganic mineral fibres can be comprised of wollastonite fibre 0～90wt%, sea bag mineral wool 0～90wt% and quartz fiber 0～90wt%.
Preferably, the wollastonite fibre that at least contains 50wt%～70wt% in described composite inorganic mineral fibres.
According to the present invention, described thickener can be for being selected from one or more the combination in polyacrylamide, sodium alginate, polyvinyl alcohol, Sodium Polyacrylate, guar gum and carboxymethyl cellulose.
Preferably, the agent of described paper-making sizing starch in replace makes by the following method: described raw material is added in pulverizer by proportioning, be crushed to all by 60 eye mesh screens, then import agitator and be stirred to white powder and get final product.
The another technical scheme that the present invention takes is: a kind of preparation method of above-mentioned paper-making sizing starch in replace agent, specifically all raw materials are added in pulverizer by proportioning, and be crushed to all by 60 eye mesh screens, then import agitator and be stirred to white powder and get final product.
The invention still further relates to the application of the above-mentioned paper-making sizing starch in replace agent of the present invention in paper and/or cardboard applying glue.
Particularly, application process is as follows: it is 6%～10% solution that the mixture of surface sizing starch substituting agent or itself and size-press starch is mixed with to mass concentration, stirs and is warming up to 85～92 ℃, gelatinization 20～30min, be cooled to 70～80 ℃, paper is carried out to top sizing.
Preferably, do not use size-press starch, the agent of paper-making sizing starch in replace replaces size-press starch completely.
According to a concrete aspect, it is 8% solution that surface sizing starch substituting agent is mixed with to mass concentration, stirs and is warming up to 90 ℃, and gelatinization 25min, is cooled to 75 ℃, and paper is carried out to top sizing.
Further, described paper/cardboard can be corrugated paper/cardboard, cop tube paper etc.
Due to the employing of above technical scheme, the present invention compared with prior art tool has the following advantages:
1. compound method is simple, only each component need be mixed by proportioning machinery;
2. can substitute size-press starch completely and carry out top sizing;
3. with low cost and sizing efficiency good, size-press starch substituting agent cost ratio starch price is cheap, and carry out under the prerequisite of top sizing substituting size-press starch completely, the WATER RESISTANCE of paper and ring crush index all can increase, and the paper problem of getting damp in summer of can also efficient solution determining.
