Abstract

The invention discloses a preparation method of rosin and its derivative resin interpenetrating network polymer emulsion, comprising the following steps: step (1): preparing rosin and its derivative resin into rosin and its derivative resin emulsion; step ( 2): Using the interpenetrating network polymer emulsion synthesis technology, polymerizing the rosin and its derivative resin emulsion with the pre-emulsion containing the network I monomer to obtain the network I polymer; step (3): combining the network I polymer with the network II monomer polymerization, that is. The invention also includes the rosin interpenetrating network polymer emulsion prepared by the preparation method and its application. The invention uses rosin and its derivative resins as raw materials to participate in the interpenetrating network polymerization reaction. The interpenetrating network polymer emulsion of rosin and its derivative resins broadens the damping temperature range, improves the damping temperature range, damping composite loss factor and material damping performance, And has good cohesiveness and adhesion.

Description

Technical field: [0001] The invention relates to the field of coating materials, in particular to a resin interpenetrating network polymer emulsion of rosin and its derivatives. Background technique: [0002] Water-based damping coatings are widely used in the rail transit industry, shipbuilding industry, machinery industry and the field of life because of their advantages such as high flame retardancy, high adhesion, corrosion resistance, aging resistance, high damping performance and convenient construction. It plays the role of sound insulation, sound absorption, vibration reduction and heat preservation. The sound insulation and anticorrosion performance of water-based damping coatings mainly depends on the performance of the damping emulsion used to manufacture the coating, including the adhesion, adhesion, flexibility, impact resistance, weather resistance and acid resistance of the water-based sound insulation and anticorrosion emulsion to the substrate. Alkali corro...
