Technical field
The present invention relates to cement products technical field for building, especially a kind of cement products is fine with polyvinyl alcohol Dimension spinning oil.
Background technology
Cement products polyvinyl alcohol (PVA) fiber is high strength high modulus PVA fiber, and manufacture method has six kinds: Wet method adds boron spinning, dry-wet spinning, gel spinning, phase separation spinning, crosslinking spinning, polyvinyl acetate Alcoholysis direct spinning, current China is to use first method.
It is that addition boric acid, as cross-linking agent, forms cross-linked gel with PVA in PVA solution that wet method adds boron spinning Structure, reduces macromolecular entanglements and is beneficial to super drawing, form highly oriented and highly crystalline high strength high modulus PVA Fiber, typical process is as follows:
PVA powder → washing → dissolving → deaeration → spinning (alkalescence coagulating bath) → damp and hot stretching → acid neutralization → wet Hot-stretch → wash → oil → xeothermic stretching → xeothermic stretching (220～240 DEG C) → oil → cut off → become Product.
Whole technical process oils the most at twice, and oiling for the first time needs oil preparation to have good permeability, for Tens thousand of fiber ectonexines are all provided that suitable smooth and coherent, eliminate electrostatic, to ensure to be dried and dry Adhesion in hot-stretching step；Further, since the drawing by high temperature of 220～240 DEG C, also require that oil preparation must have Good thermostability.Second time oil main antistatic behaviour when fibre cutting is provided, short fine laxity and Dispersibility in cement.
At present, the document of the domestic relevant oil preparation aspect research delivered is less, and the main literature retrieved is as follows:
Patent No. ZL 201210079631.8, discloses a kind of vinal for civil engineering with spinning Silk oiling agent, component composition: antistatic additive poly-cellulose quaternary ammonium salt, 16～30 parts；Emulsifying agent list glycerol Fatty acid (C8～C12) ester, 12～28 parts；Smooth agent amino-modified silicone oil, 32～55 parts；Modifying agent Nano grade inorganic silicon dioxide, 1～5 part.
Patent No. ZL 201210078776.6, discloses a kind of polyvinyl alcohol for toughness reinforcing cement concrete fine Wesy's spinning oil, component composition: antistatic additive fatty alkyl acyl hydramine, 16～30 parts；Smooth agent C18～C22 ω-3 or ω-6 unsaturated fatty acid, 12～28 parts；Stabilizer alkyl polyoxyethylene ether, 32～ 55 parts；Additive isobutyl group or n-octytriethoxysilane, trifluoro propyl or trifluoro hexyl trimethoxy Silane etc., 3～10 parts.
In these two kinds of oil preparationes, due to the composition containing molecular weight more (＞ 12%), xeothermic draw at 220 DEG C In stretching process, the amount of being fuming is bigger.
It addition, these two patents are respectively provided with the oil preparation surface modification function to fiber.Patent No. ZL Containing " poly-cellulose quaternary ammonium salt " and " nano grade inorganic titanium dioxide in oil preparation disclosed in 201210079631.8 Silicon " composition of polar group, product easily and after hydrated cementitious and vinal surface great amount of hydroxy group it Between formed hydrogen bond, cohesive force polyvinyl alcohol and cement concrete matrix between is greatly improved.
The apolar substance that oil preparation disclosed in patent No. ZL 201210078776.6 contains: alkyl alkoxy silicon Alkane or haloalkylalkoxysilan, it is possible to the polar group on vinal surface is played certain " screen Cover effect ", it is to avoid form stress with basal body interface and concentrate, improve the toughness of cement concrete.
Fiber effect in cement matrix composite, is mainly manifested in: toughness reinforcing, strengthen, hinder and split, multiple Condensation material only can produce elongation strain hardening characteristics and can be only achieved the purpose of activeness and quietness.Fiber and cement The active force character of basal body interface comprises the steps that fiber and the chemical adhesion at cement matrix interface, fiber slippage Time friction cohesive force and few fibers sliding hardening when extracting.
Research shows, the hydroxyl of PVA fiber surface, can form hydrogen with the hydrated cement product in composite Key, also exists chemical binding layer between fiber and cement, makes tensile strength and elastic modelling quantity high water outlet respectively Cement mortar Radix Achyranthis Bidentatae, the high-module high-strength PVA fiber of ten times, can effectively strengthen cement matrix composite.
But, general undressed PVA fiber surface is distributed substantial amounts of hydroxyl, makes a large amount of hydrated cement Product accumulation and tightly be bonded in fiber surface, make fiber and cement concrete matrix form the strongest change Learning cohesive force, cause stress to concentrate, when tension, fiber is not drawn out easily, and majority is pulled off, and causes toughness reinforcing Limited.
As far back as calendar year 2001, fiber surface is processed by existing foreign scholar with moderate lubrication oil, reduces fibre Dimension and the chemical adhesion of cement matrix, make few fibers continue in crack when of development and be not pulled off, But extract from cement matrix, and during extracting, have stronger sliding hardening characteristics, thus make PVA composite single shaft limit tensile strain under the conditions of low fibers content (2%) reaches 4%～8%.
In the case of oil preparation disclosed in patent No. ZL 201210078776.6, smooth agent two dodecahexaene The ω-3 of acid, gamma-Linolenic acid etc. or ω-6 unsaturated fatty acid, additive isobutyl group or n-octyl three second The silane couplers etc. such as TMOS, trifluoro propyl or trifluoro hexyl trimethoxy silane, the two combination, real Now shielding to fiber surface hydroxyl in spinning process, reaches toughness reinforcing purpose, it should be that one is preferably selected Select, but these two kinds of cost of material are higher, affect oil preparation economy.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, and the present invention provides a kind of cement products to use Vinal spinning oil, adds boron spin processes for wet method and prepares high strength high modulus PVA fiber spinning, this Invention uses the oil preparation of two kinds of different constituents, meets fiber drawing process and fibre cutting and use respectively The requirement of process, it is ensured that the spinnability of fiber and raising fiber serviceability, reduces environmental pollution, improves work Make environment.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of cement products polyethylene Alcohol fibre spinning oil preparation, adds boron spin processes for wet method and prepares high strength high modulus polyvinyl alcohol fiber spinning, uses Two kinds of oil preparationes complete spinning overall process, and its composition is as follows:
Spinning oil: consist of the following composition by weight percentage:
Polyglycereol double acid ester 40～50%；
The double polyoxyethylene ether 25～35% of tetramethylolmethane double acid ester；
Aliphatic acid polyethenoxy ether 15～25%；

Described polyglycereol di fatty acid ester, glycerol polymerization degree is polyglycereol oleic acid, the stearic acid or hard of 4～6 The double acid ester of fat acid/Palmic acid nitration mixture, it is provided that good flatness；The double fat of described tetramethylolmethane The double polyoxyethylene ether of acid esters, the Polyethylene Glycol total molecular weight of every molecular is 1200～1600, it is provided that good Good convergence；Described aliphatic acid polyethenoxy ether, polyethers averagely son amount 1600～2500, it is provided that good Good antistatic behaviour and coherent.
The construction features that the fatty acid ester of these three kinds of materials, nonionic, molecular weight are big, polarity is bigger, certainly Determine it and there is hypotoxicity, low volatility, low excitatory.
This hydrophobic group feedstock portions used by three kinds of surfactants is both from vegetable oil, and the first is with second Planting the esterification process in prepared by the first step and only have water discharge environment, latter two is at second step ethyleneoxide addition During substantially without the three wastes produce.Main material is renewable, production process low stain, the less harmful of use process Property, belong to green chemical.
Described perfluoroalkyl ethanol polyoxyethylene ether, the surface tension of 0.001% concentration of aqueous solution≤ 23dyn/cm, provides good moistening, permeability for oil preparation working solution.
The position that oils first that wet method adds in boron PVA spinning technique is being washed between xeothermic stretching process, The working solution that oils in oil groove is for containing oil preparation effective ingredient 0.8～1% aqueous solution.The tow of several ten thousand fibers, needs In seconds complete to oil, it is desirable to working solution must have good wetting permeability, guarantee tow table In the oil applying rate of fiber basically identical.
If using conventional class wetting and penetrating agent, isomerous tridecanol polyoxyethylene (3～9) as less in volatility instead Ether, if being maintained at 1% aqueous solution have relatively low surface tension, such as≤32dyn/cm, at least needs concentration of wetting agent >=0.1%, say, that at least need to account for the wetting and penetrating agent of the small-molecular-weight of oil preparation total amount more than 10%.Such Penetrating agent molecular weight is little, volatility is big, be easily generated more smog, excitatory greatly.
This oil preparation composition uses molecules surfactant and the fluorocarbon surfactant of 0.1% of more than 99% Combination, solves the contradiction of high volatility and rapid osmotic.
