Abstract

The invention discloses a high-transparency PBAT material, which comprises the following components in parts by weight: 100 parts of PBAT resin; 20-50 parts of transparent modified resin; 3-5 parts of a stiffening agent; 5-10 parts of a filler; 0.1-2 parts of a lubricant, wherein the transparent modified resin is obtained by blending a degradable polyester elastomer and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) according to a weight ratio of 2:8 to 5:5. The transparent modified resin prepared by blending the degradable polyester elastomer and the poly(3-hydroxybutyrate-co-4-hydroxybutyrate) according to a specific ratio is added, so that the transparency and rigidity of the PBAT material can be remarkably improved, and the prepared high-transparency PBAT material can be used for preparing a PBAT film with high light transmittance, good puncture resistance and excellent mechanical properties, the use requirement of the packaging field on film materials can be met, and the application of the PBAT material is further widened.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a highly transparent PBAT material and its preparation method and application. Background technique [0002] High molecular polymers have been widely used in various fields related to human life, but since most polymers are derived from petroleum and cracking products, their wastes cannot be degraded into the carbon cycle in the natural environment. The huge amount of non-degradable plastics used by human beings has caused serious pollution to the natural environment, bringing immeasurable pressure on the environment and resources. In order to deal with environmental pollution problems, research and development of degradable alternative materials with high physical properties has become a hot topic. [0003] In recent years, with the development of degradable polymers such as polylactic acid (PLA), poly(adipate-terephthalate)butylene (PBAT), polycaprolactone (PCL), a...
