Description

technical field [0001] The invention relates to a single-component silane-modified polyether sealant and a preparation method thereof. This sealant can be used in industrial fields such as automobile manufacturing, railway transportation, container manufacturing, equipment manufacturing, air conditioning and ventilation devices. Background technique [0002] The three types of high-grade elastic sealants (polysulfide type, polyurethane type and silicone type) that were developed early and have been widely used in various industrial fields have played an important role in promoting the development of various fields. However, they all have certain weaknesses, such as poor durability and deformation resistance of polysulfide sealant; silicone sealant is easy to pollute adjacent parts, and the surface finish is poor; polyurethane sealant has pungent smell and is easy to produce bubbles, etc. . These conditions have affected them in varying degrees in expanding applications, wh...
