More Information
Summary:The invention discloses a high-strength fireproof sealant and a preparation method thereof, and the high-strength fireproof sealant comprises the following components in parts by mass: 350-600 parts of alpha, omega-dihydroxy polydimethylsiloxane; 50 to 200 parts of 201 silicone oil; 300 to 600 parts of a composite flame retardant; 300 to 600 parts of a composite fireproof filling material; 100 to 300 parts of a composite inorganic filler; 10 to 15 parts of glass fiber; 10 to 40 parts of a composite cross-linking agent; 10-20 parts of a first coupling agent; 10-20 parts of a second coupling agent; 5-10 parts of a first gas generating agent; 5-10 parts of a second gas generating agent; and 0.5-2 parts of a catalyst. The fireproof sealant has excellent fireproof performance and excellent structural strength, can effectively guarantee the process of ceramization, prevents fire from spreading and smoke from diffusing, and overcomes the defects that a traditional fireproof sealant is prone to collapse and softening
