Description
Technical field
The present invention relates to technical field of textile, and in particular to a kind of sodium metasilicate modified silicon polyester nH2O ion slurries
And its preparation technology.
Background technology
Spinning sizing agent is the used natural and artificial synthesized high score with sticky effect in textile department engineering
Sub- polymer.The slurry for commonly using at present is polyvinyl alcohol（PVA）, PVA has its distinctive advantage, and the viscosity of such as slurries is steady
Fixed, the Forming ability of epithelium is big, and adhesion and wearability are strong, the intensity of energy stiffening yarns, again not affected by environment after starching, tool
There is appropriate hygroscopicity etc..But it also deposits weak point simultaneously：One is because the adhesion of PVA is too strong, being wrapped in yarn
On be difficult to leasing, it is necessary to many chemical assistant reaches easy woven effect carrying out decomposition, multipleization is needed in Final finishing
Desizing treatment is learned, but all can not completely clean out the residue of PVA, therefore greatly pollution is produced to environmental protection；The second is PVA is starched
The yarn for going out is also easy to produce electrostatic during woven, affects weaving efficiency, and is usually in the prior art the corona for using
Method processes electrostatic, when corona occurs in addition to having electric light, awns light, also with discharging sound, and produces ozone, aoxidizes
Nitrogen, ozone has strong oxidizing property, and ozone chemistry smog can destroy the immunity function of human body, induce lymphocyte chromosome lesion, cause
The skin of people is wrinkled, blackspot occur, cause pregnant woman's fetal anomaly.As the world is to health environment-friendly requirement more and more higher, it is desirable to
Disapproved containing PVA etc. non-degradable material in Export Textiles kind, to reach ecological ring standard.But in the prior art, not yet
There is a kind of slurry for being capable of substitution for PVA completely.
The content of the invention
For the deficiency that above-mentioned prior art is present, it is an object of the invention to provide a kind of sodium metasilicate modified silicon polyester pulp
And its preparation technology, to replace PVA completely.
To achieve the above object, one of the technical solution adopted by the present invention：A kind of sodium metasilicate modified silicon polyester pulp, it is special
Levy and be, this silicon polyester pulp is after carrying out removing sodium reaction by sodium metasilicate and ion exchange resin, then with binary acid and second two
Prepared by esters monomer of alcohol esterification reaction generation carries out emulsion reaction.
The two of the technical solution adopted by the present invention are a kind of preparation technologies of sodium metasilicate modified silicon polyester pulp, and its feature exists
In comprising the following steps：
The first step, cation exchange reaction：During ion exchange resin delivered into the first reactor, and toward in the first reactor plus
Water soaks, whne water pH value in it is neutral when, during sodium silicate solution put into water, the modulus of sodium silicate solution is 2.0-4.0, and
10-600min is continuously stirred, sodium metasilicate is fully reacted with cation, complete removing sodium, it is neutrality that removing sodium is reacted to solution ph
Untill, ion exchanged soln is obtained, it is standby；
Second step, the sub- hydrated sheath reaction of micelle：Ion exchanged soln that the first step is obtained is added in the second reactor, and toward the
Stabilizer is added in two reactors, starts stirring, and be warming up to 60-300 DEG C, glue particle solution is obtained, standby, wherein stabilizer
It is by weight 0.001-0.05 with ion exchanged soln amount ratio：1；
3rd step, esterification：It is in molar ratio 1-10 by binary acid and ethylene glycol:1 ratio mixing, and add water and be warming up to
60-300 DEG C is reacted, and reaction is until esterification completion, obtains middle esters monomer；
4th step, glue ester emulsion reaction：The esters monomer that the glue particle solution and the 3rd step that second step is obtained are obtained is by 1-10:
1 weight adds catalyst than mixing, and emulsion reaction is carried out at 60-300 DEG C of temperature, finished product, wherein catalyst with
Reaction solution amount ratio, is by weight 0.001-0.05：1.
Na is selected in aforementioned stable agent+Compounds.
Above-mentioned catalyst selects Na+Compounds.
The transparent newborn pasty state of sodium metasilicate modified silicon polyester pulp that the present invention is prepared, viscosity is 6-20s（Examined using No. 3
Grace flow cup is determined）.
The application of sodium metasilicate modified silicon polyester pulp in the present invention in spinning sizing agent.
Above-mentioned spinning sizing agent also includes ative starch, wax disk(-sc), and wherein ative starch refers to not being modified and purity is up to 100%
Starch.
Each raw material dosage is 30-70 parts of sodium metasilicate modified poly ester, ative starch 50-80 parts, wax disk(-sc) 1-5 in above-mentioned spinning sizing agent
Part.
Sodium metasilicate modified silicon polyester pulp of the invention be by sodium metasilicate by the reacted monomer of cation exchange removing sodium,
Combined reaction is carried out with the monomer after binary acid adds glycol reaction and form hydrone glue ionizing particle model.It has
Excellent light scattering effect and electric arteries and veins phenomenon, particle surface is silicone grease alcohol（Silica ions particle adds ethylene glycol with binary acid
The monomer of the water particle of reaction carries out the ionizing particle of combined reaction）.When medium is water, hydrone is then by hydrogen bond action face
It is connected on the silicone grease alcohol of particle surface, forms chemisorbed water layer（Hydrated sheath）.This sodium metasilicate modified silicon polyester pulp
PH value is meta-alkalescence, and the silicone grease alcohol selection of particle surface has adsorbed the OH-of medium and made surface negatively charged, so in the electric field,
This particle is moved to positive energy direction.PH value of the density of particle surface institute on-load with slurry in itself is relevant, with particle size
Unrelated, particle surface is negatively charged because of absorption OH-, and it certainly will adsorb the counter ion in base surrounding medium, such as Na+Deng sun from
Son, so that the ion of particle long face absorption constitutes electric double layer with the counter ion in solution, on the one hand counter ion receives particle surface
The attraction of ion, try hard to it is anti-they pull to particle surface, the warm-up movement of another aspect counter ion in itself makes them leave surface again
Be diffused into solution, both act on result, make the counter ion concentration for being close to particle surface larger, with surface distance
Increase, counter ion is from more to less, finally equal with surrounding medium charge density into disperse state distribution, is close to particle periphery
Counter ion is firm by particle absorption, the copolymerization for often being moved together with particle.
Compared with prior art, the beneficial effects of the invention are as follows：1st, sodium metasilicate modified silicon polyester pulp of the invention can
Uses of the substitution PVA in slashing technique completely, thoroughly avoids producing because of the environmental problem that PVA is brought, and starch finishing effect is also excellent
In PVA；2nd, this sodium metasilicate modified poly ester has excellent light scattering effect and electric arteries and veins phenomenon, not direct merely with silica
Intercept yarn and airflow strikes, it is to avoid produce electrostatic, particular avoid workman by ozone, the nitrogen oxide produced by corona method
Deng direct harm；3rd, adhesion property, permeance property are improved so that slurry yam surface out is smooth, without spot, easily point
Twist, without and head, salubrious clean, opening be clear, intensity is high, on the basis of weave quality and efficiency is ensured, reduce cost, easily
Degraded, has reached the requirement of the disposable desizing of textile industry, and non-environmental-pollution has economic benefit and social benefit higher.
