Yellowing-resistant permanent antistatic breathable film as well as preparation method and application thereof

Abstract

The invention discloses a yellowing-resistant permanent antistatic breathable film as well as a preparation method and application thereof. The breathable film comprises the following components in parts by weight: 35-55 parts of polyolefin resin; 40-60 parts of heavy calcium carbonate; 10-30 parts of a permanent antistatic agent; 0.5-2 parts of a yellowing inhibitor; 0.5 to 2 parts of an antioxidant; and 0.5-2 parts of a processing aid. The surface resistivity of the breathable film is within 1 * 10 < 9 > omega. M, the yellowing degree delta b is less than or equal to 0.4, and the moisture permeability is greater than or equal to 2159 g / m < 2 >. 24h; and the hydrostatic pressure is greater than or equal to 819 mmH2O. The breathable film can be applied to protective clothing, paper diapers and sanitary napkins.

Description

technical field

[0001] The invention relates to the technical field of modified plastics, in particular to a yellowing-resistant permanent antistatic breathable film and a preparation method and application thereof. Background technique

[0002] Static electricity in textiles and clothing is mainly generated by the friction and induction of fabrics. After static electricity is generated, it will absorb dust, particles, and pathogenic bacteria with opposite charges to the surface of clothing. In extreme cases, the discharge phenomenon will cause safety accidents. The following protective clothing application scenarios have strict antistatic requirements: (1) Hospitals, operating rooms and other places with high risk of infection; (2) Microelectronic components processing and operating occasions to prevent breakdown caused by discharge phenomena; (3) Mine, volatile solvents, dust processing and other occasions where there is a risk of explosion.
