Embodiment 1

[0069] (1) Preparation of flame retardant toughening agent

[0070] S1: Under the protection of nitrogen, the reaction pressure is controlled at 1MPa, and 210g H 12 MDA was reacted with 104 g of styrene under reflux of 200 g of ethanol at 100°C for 12 hours, and the ethanol was removed by rotary evaporation to obtain the reaction intermediate M. The characterization results of intermediate M are shown in the appendix figure 1 .

[0071] S2: Under the protection of nitrogen, 314g of intermediate M and 178g of diethyl allyl phosphate were catalyzed by 1.2g of phosphoric acid in 400g of ethanol, and reacted at 100°C for 12h, and the ethanol was removed by rotary evaporation to obtain the target toughening agent. The characterization results of the target product toughener are shown in the attached figure 2 .

Abstract

The invention provides a flame-retardant toughening agent used for a seam beauty agent, a preparation method of the toughening agent, an epoxy curing agent containing the toughening agent and an epoxyresin composition. The curing agent can meet the requirements of rapid curing and rapid cleaning of the seam beauty agent at room temperature; the introduced special toughening agent can meet the requirement for toughness without glue breakage in the cleaning process of the seam beauty agent and the requirement for flame retardancy; and the epoxy composition using the special toughening agent issuitable for requirements of a seam beauty agent in the field of building decoration.

Description

technical field [0001] The invention belongs to the field of epoxy resins, and in particular relates to a flame-retardant toughening agent, an epoxy curing agent prepared therefrom, and an epoxy resin composition used as a beautifying agent. Background technique [0002] Since 2015, the beauty joint agent in the field of architectural decoration has shown a double growth. The beauty joint agent has become an important material in the decoration industry. Compared with the white cement, glass glue, and sealant products used in the past, the beauty joint agent product has Mildewproof, waterproof, easy to scrub, rich in color and other advantages, are accepted by more and more people. [0003] The beautifying agent industry is a market dominated by builders. The considerable cost of materials determines that it must have good construction performance. It is required that there will be no glue breakage during the shovel cleaning process. Therefore, the toughness of the cured adh...
