Problems solved by technology

However, although macromolecular polyester plasticizers can reduce the mobility of plasticizers, the effect on plasticization (such as flexibility) is significantly reduced, and the hardness of the product is significantly higher than that of polyvinyl chloride containing small molecular plasticizers.

Abstract

The invention provides a toughening and plasticizer migration-resisting polyvinyl chloride material as well as a preparation method and application thereof and relates to the technical field of macromolecular materials. The preparation method of the toughening and plasticizer migration-resisting polyvinyl chloride material comprises the following steps: preparing laminar di-hydroxyl metal oxide through a high-temperature hydrothermal method; carrying out surface modification on the laminar di-hydroxyl metal oxide by utilizing dopamine, dopamine hydrochloride or a dopamine derivative, so as to obtain polydopamine modified laminar di-hydroxyl metal oxide; finally, mixing polyvinyl chloride, a plasticizer, a stabilizer and the polydopamine modified laminar di-hydroxyl metal oxide to obtain modified polyvinyl chloride. The prepared material has the advantages of relatively remarkable toughening and plasticizer migration-resisting properties and the like, and the compatibility of inorganic nanoparticles and the polyvinyl chloride is improved; furthermore, polydopamine can be used for preventing a polymer matrix from being degraded in an UV (Ultraviolet) illumination process, the performance stability of the polyvinyl chloride material is improved and the service life of the polyvinyl chloride material is prolonged.

Description

technical field [0001] The invention relates to the field of polymer materials, and in particular to a toughened plasticizer migration-resistant polyvinyl chloride material and a preparation method and application thereof. Background technique [0002] Since the industrialization of polyvinyl chloride (PVC) in the 1930s, it has been widely used in various fields of production and life due to its good comprehensive properties (good physical and mechanical properties, dielectric properties and flame retardant properties, etc.) . In order to improve the performance of polyvinyl chloride, especially for soft polyvinyl chloride, a large amount of plasticizer will be added in actual production, and the content can reach 30% to 80% or more, so as to reduce the molecular weight of polyvinyl chloride. The force, improve plasticity, elasticity, flexibility and low temperature resistance and other properties. However, in the actual use of plasticizers, such as common phthalic acid sm...
