Problems solved by technology

But they all face the same problem: in some semi-crystalline high polymers, the above-mentioned plasticizers will gradually migrate and ooze out after a period of time due to the slow crystallization of the amorphous part of the polymer, so that related products Become brittle, harden, lose original performance
However, it is hoped that the hydrophenanthrene ring of abietate, which has a huge steric hindrance effect, will act as an "anchor" to "fix" the polyether (or polyester) in the plastic matrix, thereby preparing a migration-resistant, Anti-bleeding rosin-based plasticizers, so far not reported

Abstract

The invention discloses a rosinyl plasticizer and a preparation method thereof. The rosinyl plasticizer is a compound with a structure shown in a formula I, wherein R1 is a polyether chain segment or a polyester chain segment of which the number average molecular weight is between 200 and 4,000; and R2 may be direct-chain alkyl, branched chain alkyl or inorganic metal ions. The preparation methodfor the rosinyl plasticizer comprises the following steps of: performing a series of reactions by taking maleopimaric acid anhydride and polyether of which the end group is amino or polyester of which the end group is the amino as raw materials to obtain the rosinyl plasticizer. When the rosinyl plasticizer is used, a hydrogen phenanthrene ring structure plays an 'anchoring' role by utilizing a huge space three-dimensional steric effect of the hydrogen phenanthrene ring structure in abietic acid, and the polyether or the polyester for plastification is fixed in a plastic matrix to prevent thepolyether or the polyester for the plastification from moving and seeping in the plastic matrix effectively; and the preparation method is easy and convenient to operate and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of plasticizers and their preparation, in particular to a rosin-based plasticizer and a preparation method thereof, belonging to the field of chemistry and chemical engineering. Background technique [0002] With the rapid development of plastics, printing and dyeing, textile and other industries, the annual production capacity of plasticizers in the world has exceeded 9 million tons, becoming one of the plastic additives with the largest output and sales volume. According to the types, plasticizers can be mainly divided into phthalate plasticizers (DOP plasticizers), polyester plasticizers, trimellitate plasticizers and epoxy compounds. several plasticizers. Among them, DOP plasticizers account for more than 85% of the total production and use of plasticizers. They are currently the most important general-purpose plasticizers and have been widely used in food packaging, children's toys, daily necessities, medical hy...
