Embodiment example 1

[0023]

[0024] tributylmethyl ammonium dibutyl phosphate

[0025] 3% tributylmethyl dibutylammonium phosphate and TPU pellets were melt blended with an extruder. The extruder is also equipped with a liquid feeder, and the extrusion temperature is slightly lower than the processing temperature of pure TPU resin. Then the injection molding machine prepared the samples and tested the flame retardancy.

Embodiment example 2

[0027]

[0028] The processing and testing process of the above implementation case 2 is similar to that of case 1 and will not be repeated here. Wherein, the compound is 1-ethyl-3-methylimidazolium diethylphosphate compound.

Abstract

The invention discloses a novel flame-retardant thermoplastic polyurethane plastic (flame-retardant TPU), and components, preparation and application thereof. Specifically, the flame-retardant TPU disclosed by the invention comprises polyether type TPU and polyester type TPU, the TPU flame retardant disclosed by the invention comprises an ionic liquid component, and the ionic liquid can be a single ionic liquid component, can be shared by several ionic liquids, and can also be a mixture of the ionic liquid and a traditional flame retardant. The flame-retardant TPU plastic plate disclosed by the invention can be applied to the fields of automobiles, buildings, national defense, aviation and the like.

Description

technical field [0001] The invention relates to a novel flame-retardant TPU plastic. Specifically, the patent of the present invention discloses a new type of flame retardant based on ionic liquid structure and its application in TPU plastics, which belongs to the technical field of polymers and flame retardants. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) is a polymer synthetic material with flexible segments and hard segments. According to the type of polyol, it is divided into polyether TPU and polyester TPU. The ability and easy rotation make it have better flexibility at low temperature and excellent hydrolysis resistance; while polyester TPU is more excellent in tensile strength, tear strength, wear resistance and bacteria resistance. . TPU is widely used in many fields of the national economy, such as shoe materials, automobiles, construction, pipes and other industries, and its output is increasing year by year. [0003] However, TPU i...
