Description
Technical field
The present invention relates to a kind of dipping solution, especially relate to a kind of polyester cord dipping solution.
Background technology
Along with the raising of car tire " meridianization " rate, obtained to develop rapidly as the polyester cord of one of desirable framework material of radial-ply tyre.The main feature of polyester cord is that modulus height, elongation are few, thereby the DIMENSIONAL STABILITY of tire is good, and deformation is little, and these performances are more than the polyamide fibre excellence.After polyester cord is made into cloth, must handle just with practical value through impregnation.Because the polarity of polyester molecule is lower, the crystallinity height, the chemical property torpescence, thus poor to rubber adhesion, so the bond properties of polyester cord and rubber is a long-standing critical problem always.
Polyester cord is because chemical constitution polarity is low, be difficult for forming hydrogen bond, crystal property maceration extract preferably is difficult for permeating, therefore that polyester cord and rubber interface are formed is well bonding in traditional RFL surface treatment, main at present pre-impregnation and carry out method raising composite material interface bonding strength such as surface modification with plasma when adopting epoxy or isocyanates preliminary treatment, spinning.But these preprocess methods have the defective of himself, and isocyanate ester compound is a high toxic material, and the harmful and contaminated environment of bottom organic solvent.In order to improve the impregnation effect, U.S. Pat 3307966 has been invented the technology of two-step method impregnation, the product of the better performances that hope obtains, but test by the H odd test and found that, in the composite material interface binding system, bonding broken ring mainly occurs between rubber matrix and the glue-line, illustrates that bonding between dipping solution glue-line and the rubber matrix still is not very firm.At present, the modification maceration extract complex process of domestic use, operation is many, efficient is low, price is high and interfacial adhesion is undesirable, and particularly high temperature (normal working temperature of tire) bonding strength conservation rate is little.
Summary of the invention
The objective of the invention is to overcome technical problems such as bonding force between existing in prior technology immersing glue process complexity, glue-line and the rubber matrix is strong inadequately, environmental pollution is serious, provide a kind of immersing glue process simple, the dipping solution prescription that the dipping solution performance is good.
The prescription of cord fabric thread dipping solution of the present invention is: calculate with mass fraction
The mixture of phenolic resins: 24.8～27.6 parts of butadiene-vinylpyridine copylymer latex: 33.0～34.0 parts
Styrene-butadiene latex: 15.5～16.5 parts of water: 22.1～24.8 parts
Ammoniacal liquor: 0.17～0.20 part of peregal: 0.03～0.05 part
Modified carbon black: 0.4～0.5 part
In the cord fabric thread dipping solution of the present invention, the prescription of described phenolic resins mixture is:
Resorcinol: 5.4～6.1wt% formaldehyde: 4.1～5.14wt%
NaOH: 0.1～0.16wt% surplus is that water (accounts for 88.6～90.4wt%)
Prepare by the following method at dipping solution of the present invention:
A, elder generation are dissolved in NaOH in the water by 1: 4～6, are cooled to room temperature; Resorcinol is dissolved in the remaining water then, put into reactor, be stirred to evenly, add formaldehyde again and stir the NaOH that adds dissolving after 15～20 minutes, stirred 1 hour, reaction got the phenolic resins mixture in 12～24 hours when temperature is 40～60 ℃;
B, peregal is dissolved in the water by 1: 3～5, peregal after will dissolving then and ammoniacal liquor add in the butadiene-vinylpyridine copylymer latex, add remaining water, stir;
C, styrene-butadiene latex and modified carbon black are added mixer, add the phenolic resins mixture that the A step obtains then, stir;
D, B, C two steps products obtained therefrom is mixed, stir at normal temperatures and obtained needed dipping solution in 60～100 minutes.The dipping solution of gained imports steeping vat after cyclone hydraulic separators is removed air, polyester cord rolls steeping vat impregnation 40～50 seconds through importing, obtains high performance rubberized cord then after super-dry, drafting forming.
In the present invention, resorcinol and formaldehyde react the phenolic resin type adhesive that generates solubility under the effect of base metal catalysts NaOH, this adhesive has very strong bonding force to rubber, but the curtain cotton rope still can well engage with rubber matrix under high load capacity.Butadiene-vinylpyridine copylymer latex and styrene-butadiene latex are the good adhesives of synthetic fiber and rubber, are widely used in tire cord, high strength driving belt, high-voltage tube with in the dipping solution of framework material.
The inside of the modified carbon black among the present invention is the condensed-nuclei aromatics structure, on its surface many oxygen-containing functional groups is arranged, and they mainly are carboxyl, lactone group, phenolic hydroxyl group and quinonyl.These oxy radicals can form hydrogen bond action with the latex molecule in the dipping solution on the one hand, carbon black particle can adsorb the rubber matrix strand on the other hand, produce stronger active force, so just strengthened the bonding force between cord fabric thread rubber shoe latex layer and the rubber matrix greatly, thereby the bond properties of cord fabric thread and rubber is improved.Carbon black is the very big material of a kind of specific area, can adsorb the moisture in the glue, makes it and becomes inactive bound water, is seeped in the cord fabric thread thereby reduced moisture, makes the elongation at specified load of cord fabric thread reduce greatly.The carbon blacksurface of oxidation modification is acid in addition, can delay sulfuration like this, makes sizing material have adequate time to flow and infiltrates the contact surface that the framework material gap increases framework material and rubber, the cohesiveness of raising framework material and rubber.Simultaneously, peregal is the addition product of fatty alcohol and oxirane, and is nontoxic, non-stimulated, and emulsibility, dispersiveness, water-soluble, soil release characteristics are preferably arranged, and is a kind of important surfactant, can guarantee the dispersion stabilization of dipping solution.
Beneficial effect
It is easy that the present invention has immersing glue process, characteristics such as dipping solution better performances, and the product of gained has not only improved with the bonding force of rubber matrix, and has intensity and elongation at specified load preferably, and the cloth cover color spot is few, and color is more even.
