Embodiment 1

[0033] In this embodiment, the TPU film is prepared from the following raw materials:

[0034]

[0035] The preparation method is as follows:

[0036] Grind the perlite to 150 mesh, dry each raw material at 75°C for 3 hours in advance, mix them evenly, and extrude through the casting machine. The temperature of each section of the casting machine is set as follows: the temperature of the barrel is 150°C; The temperature of the elbow is 160°C; the temperature of the elbow is 180°C; the temperature of the connection is 190°C; the temperature of the die is 190°C to obtain a TPU film.

Embodiment 2

[0038] In this embodiment, the TPU film is prepared from the following raw materials:

[0039]

[0040]

[0041] The preparation method is as follows:

[0042] Crush the perlite to 200 mesh, dry each raw material at 80°C for 1 hour in advance, mix them evenly, and extrude them through a casting machine. The temperature of each section of the casting machine is set as follows: the temperature of the barrel is 210°C; The temperature of the elbow is 190°C; the temperature of the elbow is 220°C; the temperature of the connection is 210°C; the temperature of the die is 230°C to obtain a TPU film.

Embodiment 3

[0044] In this embodiment, the TPU film is prepared from the following raw materials:

[0045]

[0046] The preparation method is as follows:

[0047] Grind the perlite to 180 mesh, dry each raw material at 75°C for 2 hours in advance, mix them evenly, and extrude through the casting machine. The temperature of each section of the casting machine is set as follows: the barrel temperature is 190°C; The temperature of the elbow is 150°C; the temperature of the elbow is 200°C; the temperature of the connection is 180°C; the temperature of the die is 220°C to obtain a TPU film.

Abstract

The invention provides a TPU (thermoplastic polyurethane) film with thermal insulation, sound insulation and noise reduction properties and a preparation method of the TPU film. The TPU film is prepared from, in parts by weight, 70-80 parts of TPU particles, 10-20 parts of polycarbodiimide, 20-30 parts of epoxy resin, 10-20 parts of polycarbonate, 10-15 parts of mica, 5-10 parts of ceramic particles and 1-5 parts of an antioxidant. The TPU film has good thermal insulation, sound insulation and noise reduction properties and good mechanical properties and has very broad application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a TPU film for thermal insulation, sound absorption and noise reduction and a preparation method thereof. Background technique [0002] With the development of industrial production, transportation, urban construction, and the increase of population density, the increase of household facilities (audio, air conditioner, television, etc.), environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Noise not only affects hearing, but also has adverse effects on the human cardiovascular system, nervous system, and endocrine system. Therefore, the demand for sound-absorbing and noise-reducing, heat-insulating and heat-insulating materials has greatly increased. [0003] Thermoplastic polyurethane elastomer (TPU) has been widely used in various industries due to its unique and excellent properties. With the ...
