Description
Technical field
The present invention relates to composite paper sizing agents, and in particular to a kind of preparation method of silk gum paper sizing agent.
Background technique
Silk gum is normally used as waste and discharges with waste water in silk process.China is silk big country, several
Over thousand, silk is only used to always filature knit silk fabric, production clothes, and silk gum is not utilized always.Annual production raw silk
About 60,000-8 ten thousand tons, the several hundred million rice of silk broadcloth, meet people clothing need while, have 30,000 tons or so of sericine with
It produces waste water to be lost, the content of organics such as silk gum in silk production waste water is caused to severely exceed, a large amount of dissolved oxygens consumed in water,
Make water eutrophication, lose self-purification capacity, not only pollute environment, but also wastes precious sericine resource.Shell is poly-
Sugar is the natural high molecular substance that content is only second to cellulose in nature, resourceful, nontoxic, tasteless, antithrombotic, resist it is quiet
Electric, alkaline-resisting, film forming and biocompatibility are good.Chitosan class Cypres are improving wood as a kind of biopolymer
Apparent advantage is all shown in terms of the intensity and printing performance of material fibre paper.This research is poly- based on natural organic matter shell
Sugar, silk gum and the excellent film forming of the two are mixed applied to top sizing with silk gum using degradation chitosan, reach silk waste water
Effective recycling of middle sericine, brings great economic benefit to silk industry.
Summary of the invention
Technical problems to be solved：The object of the present invention is to provide a kind of silk gum paper sizing agent, make full use of discarded money
Source prepares a kind of paper surface sizing agent haveing excellent performance.
Technical solution：A kind of preparation method of silk gum paper sizing agent, includes the following steps：
S1. reeling mill is discarded into degumming liquid filtering, solution is placed in 60-70 DEG C of water-bath, is concentrated in vacuo；
S2. concentrate is put into bag filter, and dialysis is removed to metal ion, obtains silk gum aqueous solution, then that silk gum is water-soluble
Silk gum is obtained by filtration in liquid；
S3. the dehydrated alcohol of 3-6 times of parts by weight is added in the silk gum prepared by step S2, filters 12h at 4 DEG C, must crystallize,
It is washed with ethyl alcohol and is filtered again twice again, it is dry under the conditions of 60-70 DEG C, obtain silk gum crystallization；
S4. silk gum is slowly dissolve into water, configures silk gum aqueous solution, the mass fraction for obtaining silk gum aqueous solution is 4-8%；
S5. by chitosan stirring and dissolving in 0.2 mol/L acetic acid solution, the mass fraction for obtaining chitosan solution is 1.5-
5%；
S6. silk gum aqueous solution is mixed with chitosan solution by 10: 0.05-0.3 mass ratio, and is added 1,2,3,4-
Silk gum and chitosan blending surface is made in butane tetracarboxylic acid, sodium lauryl sulfate, catalyst, phytosterol, oxidizing glucose aldehyde
Sizing agent is stirred and is kept the temperature at 60-70 DEG C spare.
Further, the molecule interception of bag filter is 10000-36000D in the step S2.
Further, the molecular weight of chitosan is 9 × 10 in the step S54-5×105。
Further, 1,2,3,4- butane tetracarboxylic acid in the step S6, sodium lauryl sulfate, phytosterol aoxidize Portugal
The additional amount of grape alditol and catalyst is respectively 1.5-3%, 0.1-0.6%, 0.5-1%, 1-2% and the 0.5-1% of solution quality.
Further, the step S6 catalyst is the mixture of trisodium citrate and sodium tartrate, mass ratio 1:2.
1. further, acetic acid solution concentration is 0.2 mol/L in the step S5.
Beneficial effect：Sizing agent of the invention has the following advantages that：
The moderate silk gum mixing of the chitosan and molecular weight that the present invention selects molecular weight moderate, because of the higher chitosan stream of molecular weight
Dynamic property is poor, and the lower chitosan molecule of molecular weight is penetrated into after being glued in the interfiber pore of paper, and interfiber pore is more, fine
Dimension table face film forming is poor, and silk gum will appear the irregular situation of sizing in Process of Applying Glue, therefore cooperation is made with phytosterol
Sizing uniformly, while using crosslinking agent that glue and paper are bonded, and obtains the good sizing agent of sizability.
