Description of the invention: [Technical field to which the invention pertains], the system: a mixture of a polyisocyanine mixture, a mixture thereof, and a specific mixture of polyether polyols containing IL, and the like Use for the preparation of a polyaminolated isocyanate component. Materials [Prior Art], and other materials and their preparation belong to the prior art and are described in the literature in many cases. For example, a prepolymer comprising an isocyanate group and, among other things, a binder as a binder for the formation of moisture, is an important group of the material. If such a closed container towel is not stored under the absolute exclusion of moisture, it is equal to the loss of the isocyanate group during the course of the reaction via the reaction with moisture from the atmosphere. Exposure to heat is important to facilitate such procedures. This reaction proceeds rapidly on the surface, but it can take a long time to diffuse into the interior of a layer such as a formed article, a foam or an adhesive or a sealant. As long as such a reaction occurs, the molecular weight or crosslink density is continuously increased, and the physical properties of the material change over time. "Specially. In the field of adhesives" on the one hand, the free L-isoate group of the prepolymer and the fastest possible moisture from the atmosphere are all good, and can be used just now. In other respects, the very good storage stability required for the prepolymer or the adhesive formulation comprising such 'represents a contradiction itself, as it is not always possible to completely remove the moisture from 2010 201058. Depending on the storage conditions, some amount of moisture can even penetrate through the walls of closed cylinders or other forms of containers. To speed up the curing process, external catalysts are often added to the formulation, such as, for example, organotin compounds (dibutyltin dilaurate). Or an aromatic accelerator (bis(N-fosino)diethyl ether). However, exposure of such catalysts to heat may negatively affect storage stability (especially in the case of reactive aromatic isocyanates) Based on the nature of the prepolymer, and the nature of the adhesive. Therefore, there is no shortage of attempts to provide a prepolymer containing isocyanate. The prepolymer has high reactivity with respect to moisture without the addition of an external catalyst. Such prepolymers are often based on polyether polyols or polyester polyols containing nitrogen atoms. These products are preferably used. In the use of a single component which is moisture-cured, the European Patent No. 0 002 768 describes, for example, a single component foam comprising a prepolymer comprising an isocyanate group as a starting product. Via a polyol mixture comprising from 90 to 100% by weight of an aminopolyether alcohol and/or a polyesterol with an organic polyisocyanate and further additives such as, for example, a blowing agent, in a pressurized container such as, for example, an aerosol can Obtained by the reaction. After being released to atmospheric pressure with the assistance of, for example, a valve, the mixture is foamed and rapidly solidified under the influence of moisture from the atmosphere to produce a dimensionally stable closed urethane. Foams. However, these products are not suitable for the formulation of a moisture-curing adhesive. German Patent No. 4 417 93 8 describes the preparation of organic polyisocyanates and polyols. The isocyanate group-containing prepolymer, and some of these polyols 201006858 are based on an aromatic amine based polyether polyol. These prepolymers show, in particular, a tendency to lower the crystallization effect and are suitable for Preparation of porous or compact polyamino phthalate plastics. These products are not suitable for the preparation of adhesives. The ginseng European patent _A i 471 088 describes polyisocyanates and aromatics having at least one NH2 or NHR group and / or an aliphatic starter ether polyol based polyurethane (PU) formulation which, after mixing the polyol component with the polyisocyanate, results in good or immediate compatibility, resulting in Compared with the prior art system, the mixing time can be shortened. This good compatibility is good, and it is said to be in the preparation of the polyaminomethacrylate plastic tree or plastic composition for forming articles. The articles are produced by curing in a mold prepared with a release agent. German Patent No. A 1 922 626 describes a process for the preparation of a single-component system based on the stability of ureido formic acid, which has been rapidly dried from atmospheric moisture. According to this disclosure, a suitable amount of the paint solvent (6 〇% by weight of the solvent supply) can be obtained by this method. 40 weight polymer) (such as Lai, noodle, TL, t can be used as a binder in a single-component paint system. The method can not be prepared to be suitable for the absence of _, low viscosity single component world Zhizhi _ _ _ (4) 95 / ig555 is a moisture-curing adhesive composition comprising - m vinegar-reactive components of isocyanic acid and a reaction product for isocyanate, which is reactive with isocyanate 5 201006858 The composition comprises at least one aliphatic starting with an amine having an ethylene oxide content of at least 1%. For moisture, the isocyanate-containing prepolymer having an ethylene oxide unit based on the polyether has a particularly high Affinity. This can result in increased bubble formation during the curing of the adhesive. Such bubble formation is a disadvantage for adhesive bonding. German Patent No. A 10 237 649 describes a type comprising at least one polygas. A 1-C polyurethane vinegar adhesive of a vinegar prepolymer and at least one amino polyether polyol, wherein the ether group in the amino ether polyol is from 7 to 30. In the adhesive according to the invention, the oxime content of the aminopolyether polyol is very low and is only 0.2 to 4.0% by weight. When the beech wood is glued, the bis(N-folininyl) diethyl group Under ether catalysis, this low content has resulted in a halving of the pressurization time. However, the open time, ie the treatment time, has been significantly shortened by this small amount of aminopolyether. German Patent No. 1,304,153 describes a polyamino phthalate prepolymer which has a symmetrical isocyanate group as a filler component and has an asymmetry a mixture of isocyanate-based polyisocyanates and a mixture of a polyether having a functionality of <2.5 and a polyether having a functionality of > 2.5, having a polyisocyanate group Compared with polyisocyanate with asymmetric isocyanate vinegar The value of the invention of the application is alleged to be that the prepolymer of the claimed patent interest is particularly light in color. This state of affairs is highly suspicious because the depth of the color of the prepolymer is not dependent on the polyisoacid Depending on the composition of the isomer, it does not depend on the functionality of the polyol component. In the grant of the patent European Patent _B 1 490 418, the equivalent of 4' at least the polyether component The molecular weight is strictly limited. European Patent No. 1 072 620 claims a patent benefit of a low-solvent adhesive composition comprising up to 99.999% by weight of a prepolymer comprising an isocyanide-containing group, 〇 Up to 20% by weight of the additive and auxiliary substance and 0.001 to 10% by weight of at least one of the orbolin derivative as an activator. • The composition of the pre-polymer that claims patent rights is broadly chosen, and _ therefore there is no specific property characteristic of the resulting adhesive composition. In addition, a formicin derivative is absolutely necessary, with an increased need for blending and a negative effect on storage stability. European Patent No. 1 072 621 describes a fiber-containing adhesive composition based on an adhesive composition of the European Patent _A 1 〇 72 620 and 0.1 to 20% by weight of a filler comprising at least one fiber, having an absolute The necessity is not the difference between the forint derivative and the fiber-containing sputum. © [Summary of the Invention] As a basis of the present invention, there is provided a polyisocyanate mixture for use in an adhesive without any disadvantages of the prior art. They should have low viscosity 'very good storage stability without separate activator additions, fast film formation time and the shortest possible film drying time, high initial strength and shortest possible after a short gel time High final strength after full cure time. It has been possible to achieve this by providing a polyisocyanate mixture according to the invention. 7 201006858 The present invention thus provides a diphenylmethane comprising 15 to 75% by weight of a mixture of 2 aromatic disperse acids B) 0 to 3 〇 y 氘 氘 ester mixture 2 to 30% by weight of a polymer having 3 or more aromatic cyclophenylmethane diisocyanate and 5 coats, 2 C) 40 to 85% by weight of isocyanate _ functional polyglytic
