Problems solved by technology

However, the toughening agent itself is usually flammable, and more flame retardants are needed after its addition to obtain a modified plastic with better flame retardant effect, so the production cost remains high

Abstract

The invention discloses a toughening agent with a flame-retardant effect as well as a synthesis method and application thereof, and solves the problems of high consumption of a flame retardant and high production cost in the preparation process of modified plastics in the prior art. According to the synthesis method, borate and a silane coupling agent containing acrylate groups are used as raw materials to synthesize seeds with acrylate groups, then acrylate rubber is used for coating the seeds, and finally styrene-acrylonitrile is grafted. The toughening agent prepared by the synthesis methoddisclosed by the invention is applied to preparation of modified plastics. According to the invention, hybrid Si-O-Si, B-O-Si and B-O-B structural units are creatively grafted on an ASA grafted copolymer skeleton, so that the hybrid Si-O-Si, B-O-Si and B-O-B structural units have a synergistic effect with benzene rings and N of an ASA grafted copolymer shell layer, and the flame retardant property of the toughening agent is effectively improved. When the flame retardant is applied to the field of modified plastics, the relative dosage of a flame retardant can be reduced and the cost is reduced. The toughening agent disclosed by the invention does not contain halogen and phosphorus elements and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a toughening agent with a flame-retardant effect, a synthesis method and an application. Background technique [0002] ASA combines the advantages of high gloss and processability of polystyrene resin, the mechanical properties and corrosion resistance of acrylonitrile resin, and the impact resistance and compatibility of acrylic rubber, and at the same time makes up for the toughening properties of ABS. It has a very broad application prospect due to the lack of weather resistance of the agent. [0003] ASA is widely used as a toughening agent in the field of modified plastics. Generally speaking, modified plastics need to have flame retardancy, impact resistance, high toughness, and easy processing, which makes it necessary to add flame retardants, tougheners, etc. during the preparation process. The toughening agent itself is usually flammable, and more...
