Abstract

The invention provides flame-retardant and antifungal thermoplastic polyurethane (TPU) for a cable and a preparation method of the flame-retardant and antifungal TPU, relates to antifungal and flame-retardant TPU which can be used for the cable and a preparation method of the antifungal and flame-retardant TPU, and belongs to the field of high-polymer materials. The flame-retardant and antifungalTPU is prepared from the raw materials in parts by weight: 50-70 parts of TPU, 10-15 parts of a matt agent, 10-30 parts of a halogen-free flame retardant, 0.05-0.5 part of an antioxidant, 2-10 parts of a lubricant, 1-5 parts of a compatibilizer and 0.02-1 part of an antifungal agent. The antifungal grade of the TPU cable prepared from the flame-retardant and antifungal TPU reaches the zero grade,the problem that an existing cable is prone to getting mildew and generating bacteria in a humid environment is solved, the service life of the cable is prolonged, in addition, the flame-retardant performance of the TPU is further improved, and the flame-retardant performance reaches the V0 grade. The invention further provides the preparation method of the flame-retardant and antifungal TPU, themethod is simple in preparation process, the quality is stable, the production efficiency is high, and large-scale production can be achieved.

Description

technical field [0001] The invention relates to the modification of a polyurethane elastomer, in particular to a flame-retardant and anti-mold thermoplastic polyurethane (TPU) elastomer for cables and a preparation method thereof, belonging to the field of polymer material processing. Background technique [0002] At present, there are mainly two types of coating materials for cables. One is an elastomer material based on polyvinyl chloride (PVC), which can basically meet the basic requirements of cables and is low in price. However, the amount of smoke generated during combustion Large, and produce toxic and harmful gases, do not meet the requirements of environmental protection, which greatly limits its scope of application; the other is an elastic material based on thermoplastic elastomer, which is easy to process, has a wide range of hardness, excellent performance, and is in line with environmental protection. Therefore, it is widely used in cables and becomes a researc...
