Problems solved by technology
[0007] Although the existing technology has given some solutions to the lightweight of polyurethane elastomers, most of them are aimed at the application of shoe sole materials
However, there are no relevant reports on the application of various line cables such as automotive application cables and optical fiber cables. Due to different application scenarios, polyurethane elastomers used in automotive application cables, optical fiber cables, etc. need better mechanical properties. , and at the same time need to take into account a certain flame retardant performance and lightweight

Embodiment and
[0067] The preparation method of embodiment and comparative example polyurethane elastomer:
[0068] 1) At 40°C, mix and stir the isocyanate component A and the isocyanate-reactive component B respectively for further use;
[0069] 2) At 40°C, the isocyanate component A and the isocyanate-reactive component B are uniformly mixed by a high-speed mixer, and then poured into a mold at 140°C. After reaction curing molding, demoulding, and aging, light weight can be obtained Quantification of polyurethane elastomers. The raw materials used in Examples and Comparative Examples are listed in Table 1.

Abstract
The invention provides a light-weight polyurethane elastomer as well as a manufacturing process and application thereof. The polyurethane elastomer is obtained by reacting an isocyanate component and an isocyanate reactive component, the isocyanate reactive component comprises polyether polyol 1, polyether polyol 2, a chain extender, a cross-linking agent, a catalyst, white phosphorus calcium stone, a dispersing agent and hollow microspheres. On the basis of low density and light weight, the polyurethane elastomer disclosed by the invention also has excellent mechanical property and flame retardant property, and can be used for various line cables such as automobile application cables, optical fiber cables and the like.
Description
technical field [0001] The invention relates to the field of polyurethane materials, in particular to a lightweight polyurethane elastomer and its manufacturing method and application. Background technique [0002] Polyurethane elastomer has a unique structure of soft and hard block copolymers. This structure makes polyurethane elastomers have high strength, high elasticity, good wear resistance, oil resistance, low temperature softness, high elongation, and good corrosion resistance. Excellent performance. At the same time, it has both the high elasticity of rubber and the ease of processing of plastics. It has been widely used in shoe materials, plates, pipes, films, cables, auto parts, medical treatment, sports and leisure and other fields. In recent years, due to the growing demand for lightweight materials, the development of lightweight polyurethane elastomers has become a current research hotspot. [0003] Patent CN102660113B discloses a thermoplastic polyurethane m...
