Abstract

The invention relates to a one-component silicyl polyether sealing adhesive and a preparation method thereof, belonging to the technical field of one-component silicyl polyether sealing adhesive; the one-component silicyl polyether sealing adhesive mainly solves the problems that the existing silicyl-terminated polyether sealing adhesive has low tensile strength, and the tensile strength is only 0.5-3.5MPa and affects the application range; the one-component silicyl polyether sealing adhesive comprises the following ingredients: 20-40 parts of silicyl-terminated polyether, 5-20 parts of plasticizers, 30-50 parts of incremental fillers, 4-10 parts of reinforcing fillers, 0-20 parts of coloring agents, 0.1-5 parts of thixotropic agent, 0.01-1 part of ultraviolet absorber, 0.01-1 part of radical scavenger, 0.1-3 parts of moisture content scavenger, 0.1-5 parts of adhering accelerator and 0.1-3 parts of catalysts; the one-component silicyl polyether sealing adhesive has high tensile strength, the tensile strength can reach 5.12MPa, and the one-component silicyl polyether sealing adhesive is used for sealing adhesive of various materials and splicing, thereby having wide application on automobile making industry, railway transportation industry, container manufacturing industry, metal and nonmetallic processing industry, equipment manufacturing, air conditioner and ventilator devices.

Description

Technical field [0001] The invention belongs to the technical field of single-component silyl-terminated polyether sealing adhesives, and specifically relates to a high-strength single-component silyl-terminated polyether sealing adhesive and a preparation method thereof. Background technique [0002] Silane-terminated polyether sealant is also known as silicone modified polyether sealant, modified silicone sealant and MS sealant. The silyl-terminated polyether sealant inherits the advantages of silicone sealant and polyurethane sealant, showing excellent weather resistance, durability, high resistance to deformation and displacement, good adhesion, coating, environmental friendliness, The advantages of low staining, low viscosity and excellent workability. It has been promoted and applied in the automobile manufacturing industry, railway transportation industry, container manufacturing, metal and non-metal processing industry, equipment manufacturing, air conditioning and venti...
