Problems solved by technology

However, at present, PVDC as a packaging material often has relatively poor thermal stability, and its thermal decomposition temperature is 100-120°C. When it is heated or placed at room temperature for a long time, it will produce double bond conjugation, escape hydrogen chloride, and create cavities between molecules. , Barrier failure, leading to the need to add preservatives and other additives to the food to increase the storage time, often have a certain degree of harm to the human body

Abstract

The invention relates to copolymerized REPVDC alloy solid resin as well as a preparation method and application thereof. The copolymerized REPVDC alloy solid resin is prepared from the following components: a mixed monomer and a dispersing agent thereof, a mixed monomer initiator, a terminator, a neutralizing agent, a defoaming agent and deionized water. The distorted crystalline structure of a side chain of polyvinylidene chloride (PVDC) can be changed into an orderly arranged side chain crystalline structure by adding a functional monomer for realizing copolymerization with vinylidene chloride, so that the strength, toughness and barrier property of the original PVDC are greatly improved, the mechanical properties and heat resistance of a new material are respectively increased by 0.3-3times and 20-60% on the original basis, and the new material is endowed with memorability. The copolymerized REPVDC alloy solid resin is simple in preparation technology and low in cost, thus having good application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a copolymerized REPVDC alloy solid resin and its preparation method and application. Background technique [0002] As a packaging material with good comprehensive barrier properties, polyvinylidene chloride (PVDC) polymer material is safe and non-toxic, and has a wide range of applications in the field of food packaging. However, at present, PVDC as a packaging material often has relatively poor thermal stability, and its thermal decomposition temperature is 100-120°C. When it is heated or placed at room temperature for a long time, it will produce double bond conjugation, escape hydrogen chloride, and create cavities between molecules. , Barrier failure, leading to the need to add preservatives and other additives to food to increase storage time, often have a certain degree of harm to the human body. Contents of the invention [0003] The technical problem to be solved by th...
