Abstract

The invention relates to the field of film technology, in particular to a multifunctional sound-insulating, heat-insulating, heat-insulating, and anti-static polyester film and its preparation process, including: a sound-absorbing layer, a PET base film layer, an adhesive layer, a sound-insulating layer, and a first heat-insulating and heat-insulating layer layer, a core layer, a second heat insulation layer, and an antistatic layer, the core layer is located between the first heat insulation layer and the second heat insulation layer. The invention has the ability to block more than 99% of ultraviolet absorption and more than 85% of infrared absorption, and has an excellent anti-static effect, and can effectively prevent dust and impurities from being adsorbed, and solves the problem that the prior art has no sound insulation function and heat insulation function , heat preservation function, antistatic function and the technical problem of using a film with good effect.

Description

Technical field[0001]The present invention relates to the field of thin film technology, and in particular, to a multi-functional sound-insulating thermal thermostatic polyester film and a preparation process thereof.Background technique[0002]The film has good mechanical properties, rigidity, hardness, toughness, very widely used in production and life, and often requires the protection of articles by films in the field of food, medicine, chemicals. The use of films has brought great convenience to people.[0003]For the use of the film, sometimes it is necessary to reduce the noise of the item, prevent noise from being propagated to the outside, which is harmful to the outside world; it may also need to block the external noise by the film to prevent external noise to protect the film protection of the film. Effect; or It is necessary to prevent thermal burns of the article by thin film, or to ensure that the temperature generated by the item will not be lost immediately; it may also...
