Abstract

The invention discloses a bio-based solvent-resistant plasticizer and a preparation method thereof. The bio-based solvent-resistant plasticizer is formed by combining modified isosorbide dioleate, tri (ethyl butyrate) isocyanurate and tetrabutylammonium chloride. The components of the bio-based solvent-resistant plasticizer prepared by the invention cooperate with one another, so that the bio-based solvent-resistant plasticizer not only has a good plasticizing effect, but also can improve the flexibility, tensile strength, extraction resistance and degradability of polyethylene resin and endow polyethylene with good flame retardant property, and meanwhile, the preparation raw materials are green and environment-friendly and have good biocompatibility.

Description

technical field [0001] The invention relates to the technical field of plastic product additives, in particular to a bio-based solvent-resistant plasticizer and a preparation method thereof. Background technique [0002] In the past 60 years, plastic has become an indispensable and widely used new material in the world, which is widely used in food packaging, medical supplies, electronic products, building materials and other fields. The choice of plasticizer plays a crucial role in the performance and safety of plastic products. Several traditional plasticizers have different plasticizing effects for different polymers. When choosing plasticizers, in addition to good biocompatibility with polymer materials, some other characteristics, such as leaching resistance, Flexibility, thermal stability, and resistance to factors such as moisture and light all need to be considered. More than 300 different types of plasticizers are known, of which more than 50 are in commercial use...
