The tyre cord fabric dipping glue comprises polyisocyanate, acrylic ester and ether monomers, wherein the polyisocyanate is selected from one or more compositions of polyisocyanate containing more than two isocyanate groups; the preparation method comprises the following steps: putting the polyisocyanate, the acrylic ester and the ether monomers together, and then stirring for 25 to 40 minutes at 35 to 50 DEG C, wherein the dipped tyre cord fabric is formed by being dipped in tyre cord fabric dipping glue. Compared with the prior art, the tyre cord fabric dipping glue, the preparation method and the dipped tyre cord fabric have the benefits of simple processing equipment, energy conservation, high energy utilization, no solvent emission, high safeness and no pollution, high curing speed, high production efficiency, and superior adhesive property of produced cord fabric and rubber.
Description
Technical field
The invention belongs to tire manufacturing techniques field, relate to a kind of cord fabric impregnated resin, particularly a kind of polyamide cord fabric impregnated resin, preparation method and impregnation polyamide cord fabric.
Background technology
Cord fabric: make warp with powerful strand, with in, ramuscule single thread makes latitude, knits the tire skeleton fabric of system.Closely, weft yarn arrangement is sparse for the arrangement of its middle longitude, and shape is like curtain, and hence obtain one's name cord fabric.
Cord fabric is used as the skeleton of the rubber such as tire, makes it bear immense pressure, impact load and sharp pounding.Can find out that cord fabric is the important materials affecting tyre performance and life-span.Its middle longitude (also known as cord fabric thread) bears load, and weft yarn is fixing through line position.To the requirement of cord fabric thread be: 1. intensity and initial modulus high; 2. heat-resisting; 3. endurance; 4. Stability Analysis of Structures; 5. can and rubber adhesion.
Cord fabric is of a great variety, and with regard to polyamide cord fabric, master operation is production and the impregnation of fiber, and both directly have influence on the performance of product.
With regard to impregnation aspect, prepare with RFL(RFL impregnated resin in the market: resorcinol and formaldehyde are pre-configured to RF solution; Also will by butadiene, styrene, 2-vinylpyridine by emulsion polymerisation synthesis VP glue; Finally RF solution and VP latex are mixed into RFL) impregnated resin dipping polyamide cord fabric.This RF solution preparation is that resorcinol and formaldehyde polycondensation under the catalytic action of NaOH form for 7 hours, needs to consume the plenty of time, and curing mode is hot baking and curing in addition, consumes mass energy.
Summary of the invention
The object of the present invention is to provide a kind of polyamide cord fabric impregnated resin, preparation method and impregnation polyamide cord fabric, use irradiation to be cured drying, have and prepare advantage that is simple, gum dipping process efficient energy-saving.
In order to achieve the above object, the invention provides a kind of polyamide cord fabric impregnated resin, be made up of polyisocyanates, acrylate and alkene ether type monomer, described polyisocyanates is selected from the composition of one or more in the isocyanates containing two or more isocyanate group.More preferably, described polyisocyanates is selected from the composition of one or more in methyl diphenylene diisocyanate, 4,4', 4''-triphenylmethane triisocyanates, 2,2'-dimethyl-3,3', 5,5'-triphenyl methane tetraisocyanates.
The present invention is based on following theory:
Polyisocyanates and acrylate reactions, be prepared into a polyisocyanates and acrylate addition product solution,-NH-the group of residual-NCO group and polyamide cord fabric is utilized in addition product solution to play cross-linking reaction, glue is attached on polyamide cord fabric in chemical bond mode, then makes the double bond in addition product solution produce radical polymerization with the curing mode of irradiation and solidify.
Further explain, polyisocyanates and acrylate combine, and obtain an intermediate product simultaneously containing-NCO group and carbon-carbon double bond.This intermediate product-NCO group and polyamide fibre in-NH-radical reaction, be connected on polyamide fibre; Carbon-carbon double bond in the carbon-carbon double bond of this intermediate product and alkene ether type monomer is opened, and polymerization, finally solidifies.
Wherein, the isocyanate group sum in impregnated resin is in excess in the method for the hydroxyl in acrylate, and right and wrong are usually shown in for those skilled in the art.
Preferably, described acrylate is monohydroxy acrylate.More preferably, described acrylate is selected from the composition of one or more in hydroxyethyl methylacrylate, hydroxy-ethyl acrylate, hydroxy propyl methacrylate, hydroxypropyl acrylate, 4-hydroxybutyl acrylate or 3-hydroxyl-1-adamantyl methacrylate.
Preferably, described alkene ether type monomer is selected from the composition of one or more in propenyl ether, vinyl-n-butyl ether or propenyl benzyl oxide.
Preferably, polyamide cord fabric impregnated resin of the present invention, with parts by weight, is made up of the polyisocyanates of 100 ~ 300 parts, the acrylate of 70 ~ 240 parts and 10 ~ 40 parts of alkene ether type monomer.
Present invention also offers a kind of preparation method of described polyamide cord fabric impregnated resin, together with polyisocyanates, acrylate are placed in alkene ether type monomer, stir 25 ~ 40 minutes at 35 ~ 50 DEG C.
The present invention additionally provides a kind of impregnation polyamide cord fabric simultaneously, is flooded form by described polyamide cord fabric impregnated resin.
In order to more comparatively visual interpretation inventive principle, be illustrated below by way of chemical reaction:
For the polyisocyanates of three-functionality-degree and monohydroxy acrylate reactions,
The first step, the generation of impregnated resin:
Add alkene ether type monomer and regulate impregnated resin viscosity.
Second step, the cross-linking reaction of impregnated resin and polyamide fibre:
3rd step, electron beam radiation curable impregnated resin:
1≤n≤1000；1 ≤m≤1000
Compared with prior art, beneficial effect of the present invention:
Process equipment is simple; Save the energy, capacity usage ratio is high; Solvent-free discharge, safety non-pollution; Curing rate is fast, and production efficiency is high; The cord fabric produced and rubber bound superior performance.
