Transparent polyurethane elastomer component material and using method thereof

Abstract

The invention provides a hypergolic transparent urethane elastomer combination material, wherein the polymer component comprises 2000-6000 molecular weight polyether polyol, aromatic diamine MOCA, accelerant and light-stability agent; the prepolymer (NCO%=7%-10%)is made by the mixture of 2000 molecular weight, 2 functionality polyether polyol and more than two-type diisocyanate with toluene diisocyanate at 70-90Deg. C. The weight ratio of prepolymer and polymer is 1:1, the mixing temperature is 25Deg. C-40Deg. C, and the vulcanizing temperature is 60Deg. C-75Deg. C. The elastomer not only guarantees transparency, but also is provided with the good mechanic property, which makes the light transmittance ratio of the product more than 85%, makes the product produce in the lower temperature, and is fit for manufacturing the transparent skating shoe wheel or the slide board wheel.

Description

technical field

[0001] The invention belongs to polyurethane elastomers, in particular to a transparent polyurethane elastomer composite material and its application method. Background technique

[0002] Polyurethane is a polymer synthetic material with properties between rubber and plastic. It is characterized by a wide range of hardness adjustment. It has both the elasticity of rubber and the hardness of plastic, and has good mechanical properties, wear resistance and resilience. . Because of its advantages, it is used to make wheels of roller shoes, but it is difficult for ordinary polyurethane elastomers to be colorless and transparent. Therefore, although it has excellent wear resistance and resilience, it is not beautiful in appearance and is not welcomed by people. . In order to obtain transparent polyurethane elastomers, the mechanical properties, resilience properties and wear resistance properties of the products are often compromised. Like this just lost the ad...
