Embodiment 1

[0032] In the present embodiment, the TPU film is prepared from the following raw materials:

[0033]

[0034] The preparation method is as follows:

[0035] The perlite is pulverized to 150 mesh, and each raw material component is pre-dried at 75 ° C for 3 hours, mixed evenly, and extruded through a 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 filter screen The temperature of the elbow is 180°C; the temperature of the connection is 190°C; the temperature of the die head is 190°C, and the TPU film is obtained.

Embodiment 2

Abstract

The invention provides a heat insulation, sound absorption and noise reduction TPU film and a production method thereof. The TPU film is produced from, by weight, 50-60 parts of polyester TPU particles, 10-20 parts of polycarbodiimide, 30-40 parts of epoxy resin, 5-10 parts of polycarbonate, 5-10 parts of mica, 2-5 parts of ceramic particles and 1-3 parts of an antioxidant. The sound absorption coefficient of the TPU film is 0.96-0.99, so the TPU film has good sound absorption and noise reduction performances; the heat conduction coefficient is 0.03-0.05 W / m.k, so the TPU film has very good heat insulation property; and the tensile strength of the TPU film is 62-68 MPa, the elongation at break is 598-632%, and the tear strength is 140-145 MPa, so the TPU film has good mechanical performances. The TPU film produced in the invention is a heat insulation, sound absorption and noise reduction TPU film with good comprehensive performances, and has wide application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a thermal insulation, sound absorption and noise reduction TPU film and a preparation method thereof. Background technique [0002] With the development of industrial production, transportation, urban construction, as well as the increase of population density, the increase of household facilities (audio, air conditioner, TV, etc.), the 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 adversely affects people's cardiovascular system, nervous system, and endocrine system. Therefore, the demand for sound absorption and noise reduction, thermal insulation materials has greatly increased. [0003] Thermoplastic polyurethane elastomer (TPU) has been widely used in various industries due to its unique and excellent characteristics. With the development of te...
