Abstract
The invention relates to microcellular polyurethane elastomers which can be produced by reacting polyisocyanates with compounds having at least two hydrogen atoms which are reactive with isocyanate groups. Said elastomers are characterised in that they contains a combination a) made of ai) an aromatic phosphite having a phosphorus content of between 9,00 - 11,00 wt.- %, and aii) an amine compound. The molar ratio between ai) and aii) is between 0,005 - 4,0.
Description
The integral polyurethane foam usually is known as " microcellular polyurethane elastomer ", and also be called " MPE " hereinafter, and they are known for some time, for example are used to produce sole.They for example are described in Kunststoffhandbuch[plastics handbook], the 7th volume " urethane ", the 3rd edition, 376 pages and subsequently in each page.They are by making polyisocyanates and having at least two compound reactions that isocyanate group is reactive hydrogen atom and prepare.The compound that is used for this reaction usually is polyesterols.This makes material have outstanding use properties such as snappiness, high tensile and tear propagation strength or low abrasion.Simultaneously, this system can be processed with high process reliability.The hydrolytic resistance that is material based on a shortcoming of the microcellular polyurethane elastomer of polyesterols is low.Described low hydrolytic resistance is caused by the tropism that ester group has hydrolytic deterioration.The fracture of ester group causes the decline of polymkeric substance molar mass and causes the deterioration of use properties, may cause the completely destroy of material under extreme case.
Therefore in the past taked various effort to improve the stability to hydrolysis of such material.
The improvement that has proposed is to use special polyesterols based on a kind of method of the stability to hydrolysis of the microcellular polyurethane elastomer of polyesterols.Here should mention for example DE 3 144 968, wherein use, 4-butyleneglycol, 1, the polyesterols of 6-hexylene glycol and neopentyl glycol based on hexanodioic acid, 1.In addition, have more hydrolytic resistance in order to make polyesterols, replacement or the part of having described polyesterols replace.
The another kind of method of improving hydrolytic resistance is for using special additive, and its consumption is less than 10 weight % usually.For example, EP 965 582 has described the use acid anhydrides, and DE 19 710 978 has described the combination of using lactone and carbodiimide.
Yet, can have shortcoming usually by the solution that prior art obtains.In some cases, realize higher hydrolytic resistance really, but before aging, only obtained inadequate use properties simultaneously.In addition, some solution can not realize actually owing to higher raw materials cost.This may for example take place under the situation of the special additive that uses particular polyesters alcohol or higher consumption.Another shortcoming of many solutions that can be obtained by prior art is the decline of component stability in storage.In addition, especially when stability to hydrolysis was had high the requirement, the efficient of many solutions was low excessively.
In microcellular polyurethane elastomer, use phosphorous acid ester normally known and for example be described in Kunststoffhandbuch, the 7th volume, " urethane ", the 3rd edition, the 120th page and subsequently in each page.At this moment, phosphorous acid ester is used as the antioxidant auxiliary.Caused synergistic function with being used in combination of typical antioxidant (as sterically hindered phenol), prevented that simultaneously the efficient of thermal oxidation process is able to remarkable increase.
