A flame retardant module and a preparing method thereof

Abstract

The invention discloses a flame retardant module and a preparing method thereof, and relates to the field of fire-proof sealing materials. Raw materials of the module include modified vermiculite powder, silicon carbide powder, flame retardant resin, bauxitic rock, light-burned magnesia, aluminum silicate fibers, ethyltrimethoxysilane, N-hydroxymethyl acrylamide, acrylic acid, a calcium oxide expanding agent, a flame retardant, a foaming agent and a foam stabilizer. The preparing method includes fully mixing the raw materials and casting the mixtures into the mold in stages, pressing, naturally airing, and molding. The module is simple and convenient to prepare and is high in molding and drying speeds. A finished product of the module has characteristics of high compressive strength and a high fire-proof flame retardant degree, has greatly prolonged service lifetime, and is suitable for large-scale production and application.

Description

technical field [0001] The invention relates to the field of fireproof sealing materials, in particular to a fireproof module and a preparation method thereof. Background technique [0002] The fire-blocking module is a kind of fire-proof sealing material, which is mainly used for the sealing of holes such as wires and cables passing through walls and floors, and the use of cable trenches as fire-blocking partitions. The fire retardant module can effectively prevent wires and cables from spreading to adjacent spaces through holes due to heat and fire, endangering connected electrical equipment and causing greater losses. [0003] At present, in the prior art, there are three problems in using fire-blocking modules to seal holes and fire-blocking cable trenches: 1) Large volumetric weight: fire-blocking modules with large volumetric weights will increase the load on the hole building; 2. ) Insufficient heat insulation and refractory performance: the heat insulation and refra...

Problems solved by technology

[0003] At present, in the prior art, there are three problems in the use of fire-blocking modules to block holes and fire-blocking cable trenches: 1) large bulk density: a fire-blocking module with a large bulk density will increase the load on the hole building; 2. ) Insufficient heat insulation and fire resistance performance: the heat insulation and fire resistance performance of the fire retardant module is the key to reflecting its application value. Therefore, the selection of raw materials for heat insulation and refractory preparation is particularly important; 3) Poor processing and shaping: this situation will lead to fire resistance Module production is difficult, and processing is time-consuming and labor-intensive
