Description
Technical field
The present invention relates to a kind of fiber carried out surface modification to improve itself and the method that strengthens the object bond strength, also relate to this through the fiber of surface modification and strengthening rubber for example or plastic products in purposes.
Background technology
Because the intensity of rubber itself for example can not satisfy the requirement as purposes such as doughnut, transport tape, driving belts, so need in rubber, introduce fortifying fibre as framework material usually.Known fortifying fibre has for example cellulose fibre, fatty polyamide, polyester, aramid fibre etc.The shortcoming of this fortifying fibre is that the quantity of its surface functional group is low, in some occasions, is difficult to combine with rubber well with the performance humidification.
In order to improve the adhesion of fiber and rubber, the method that prior art is employed in fiber surface application of adhesive coating usually make it the surface have can with the interactional functional group of rubber.
For example; In order to improve the adhesion between adhesive coating and the fortifying fibre; The artificial Japanese Mitsubishi Rayon that assigns, the United States Patent (USP) 3,855 of Ltd; 168 disclose a kind of adhesive-dipping liquid that is used for fortifying fibre, and it comprises a kind of water-borne dispersions that contains halogenated phenols compound, thermosetting resin and rubber latex.During use with this adhesive-dipping liquid dipping Polyester Fibers, drying, 200-260 ℃ of heat treated, be bonded in the rubber it and sulfuration through hot pressing.The inventor of this United States Patent (USP) thinks why this adhesive can obtain good strengthening the property is because can easily infiltrate polyester fiber inside at the compound of halogenated phenols described in the heat treatment process.Because the polar interaction between the phenyl ring that the solubility parameter of halogenated phenols compound has more strengthened adhesive near the solubility parameter and the substituted halogen atom of polyester than conventional adhesive component in the said maceration extract and the phenyl ring of polyester, thereby improved the adhesive force of adhesive composition on polyester fiber.
Though reaching, the fortifying fibre of above-mentioned prior art strengthens the for example purpose of rubber; But since adhesive coating through immersion coating to fiber, so be to mutually combine between this adhesive coating and the fiber itself through physical force (for example the engagement between hydrogen bond, Van der Waals force, the interface etc.).This adhesion strength also is not enough to form high-quality rubber sometimes.
In order to improve the bond strength between fiber and the elastomer, the method for the people that assigns a kind of manufacturing fortifying fibre based on chemical bonding for the United States Patent (USP) 3,307,966 of E.I.du Pont de Nemoursand Company discloses.It is based on the water solution system of epoxide and blocked isocyanate.The advantage of this fiber reinforcement method is that it is eco-friendly that the fiber thread rope of wherethrough reason has improved bond properties and its water-based system with rubber, but the rigidity of the modified fibre cotton rope of finding in producing to make in this way still can not satisfy in the production needs of high-end products such as V-type band.
In order further to improve the good cohesiveness of the rigidity of the fiber thread rope of handling and maintenance simultaneously and rubber, generally adopt maceration extract system in the industry now based on organic solvent such as toluene.It has been generally acknowledged that under the effect of organic solvent the material that isocyanates etc. are active can be diffused into the inside of fiber preferably and react, and produces strong bonding effect.Although use this method for modifying fibers can improve the bond strength of fiber thread rope and rubber simultaneously and the modified fibre cotton rope of acquisition has gratifying rigidity; But because this maceration extract use is organic solvent; Not only solvent cost is high in the production process, and causes environmental pollution and employment security harm easily.Severe day by day along with environmental regulation is badly in need of seeking a kind of method of modifying of fiber thread rope of the maceration extract system that substitutes this organic solvent type.
Henk A A van Aalten has proposed a kind of isocyanates water-based dipping system (Ionothane
) based on end-blocking in the report of 148 rubber branches of American Chemical Society.But this impregnate layer material can discharge acid gas in subsequent reaction activation process, thereby operator and machine are had harm.
Consideration based on above multiple factor; The dipping system that needs a kind of aqueous solution type of exploitation; Thereby not only have between adhesive phase and the fiber in the modified fibre that makes with this dipping system strong chemical bonding can with strengthen object and take place strong bonding; And the modified fibre that dipping back forms has gratifying rigidity, and is all in the production needs of high-end products such as V-type band to satisfy.
The content of invention
Goal of the invention of the present invention provides a kind of fibre, between its outer adhesive covering and the fiber bodies mainly through chemical force but not physical force combine, thereby have good adhesion strength.
Another goal of the invention of the present invention provides a kind of method of modifying of said fiber surface modification, and this method is not used contaminated environment and had the organic solvent of occupational hazards, and the material of being safe from harm property produces in the process of producing.
A further object of the present invention provides the purposes of a kind of fibre of the present invention aspect raising rubber (for example doughnut, aero tyre, transport tape, driving belt etc.) intensity.
Therefore, one aspect of the present invention provides a kind of fibre, and it comprises fiber bodies and is grafted on the adhesive phase on the said fiber bodies outer surface.
Another aspect of the present invention provides a kind of manufacturing approach of said fibre, and it comprises the steps:
Fiber bodies is provided;
A kind of water-based steeping fluid composition that is used to form adhesive phase is provided, and it comprises monomer, initator and other optional additive; With
