Problems solved by technology

[0004] At present, many fire-resistant adhesive products use halogen-based, phosphorus-based and other flame-retardant fillers, but this type of fire-resistant adhesive will release toxic and harmful substances during the flame-retardant process, which will affect human health and the environment.
In addition, some fireproof adhesives use environmentally friendly aluminum-magnesium flame-retardant fillers mainly based on aluminum hydroxide and magnesium hydroxide, but a relatively high addition ratio is required to exert the flame-retardant effect. Composite index requirements for performance and aging resistance

Abstract

The invention relates to a phthalimide modified room temperature vulcanized fireproof silicone rubber and a preparation method thereof. The modified room temperature vulcanized fireproof silicone rubber is modified by a specific proportion of phthalimide to It is prepared from alkane polymers, flame retardant fillers, reinforcing fillers, plasticizers, colorants, flame retardant accelerators, crosslinking agents, composite silane coupling agents, and catalysts. The phthalimide-modified fireproof silicone adhesive can meet the requirements of various types of doors, windows, curtain walls, sealing and fireproofing. The introduction of N element in dicarboximide-modified hydroxyl-terminated polysiloxane polymer and the addition of environmentally friendly flame-retardant fillers and flame-retardant accelerators in the formula make the product's flame-retardant grade reach FV0 through the synergy of the three.

Description

[0001] Technology neighborhood [0002] The invention relates to the field of fireproof glue, in particular to a phthalimide modified room temperature vulcanization fireproof silicone rubber and a preparation method thereof. Background technique [0003] With the rapid development of urbanization and construction industry in China, more and more high-rise complex buildings have been widely constructed. Safety is the primary factor to be considered in architectural design, and fire protection of high-rise buildings has become the top priority. Once a fire occurs, it is very important to prevent the fire from spreading and make the material have a certain fireproof time. Fire blocking is the most effective fire prevention and smoke isolation method in architectural design at present, and is widely used in door and window systems and various pipes. Sealants are often used in door and window systems and various pipes. Therefore, more requirements are put forward for the sealant,...
