More Information
Summary:The invention belongs to the technical field of materials, and relates to a room temperature vulcanized dual-component polythioether sealant, a preparation method and application method thereof. The sealant is characterized by being composed of a component (A) and a component (B) according to a weight ratio of 8:1-10:1. The preparation method comprises the following steps: processing a low-density filling material, preparing the component (A), and preparing the component (B). The invention provides a room temperature vulcanized dual-component polythioether sealant, a preparation method and application method thereof. The density of the sealant is lower than 1.30 g/cm3. At the same time, the mechanical properties, anti-aging performance, and heatproof performance of the sealant are all improved. The requirement on the service life of sealant in airplane sealing is met.
