Abstract
The invention provides a fire-resistant silicone blocking material, which relates to a fire-resistant blocking material for seams when pipelines pass walls. The fire-resistant blocking material contains no toxic component, is fire resistant, of stretching and compression elasticity, can compensate the displacement caused by vibration in mechanical pipelines and settlement of buildings, and are easy for maintaining pipelines and cables. The invention uses silicon oil, silica gel, color additive, reinforcing agent, structure controlling agent, retardant, catalyst and solvent, and is characterized in that the substrate gel is synthesized by silica gel, silicone oil, reinforcing agent, structure controlling agent and solvent. At using, a black even thick gel that is prepared by synthesizing the substrate gel, silicone oil and color agent is mixed at 1:1 proportion with a white even thick gel that is prepared by synthesizing the substrate gel, silicone oil, retardant, catalyst and solvent, then they are vulcanized and foamed to form an elastic foam body. The invention is for blocking in a fire resistant way the seams when pipes, cables, vent tubes pass walls.
Description
Technical field:
The present invention relates to be used for the inner pipeline through walls of slit through walls fireproof blocking, especially nuclear power factory building, ships, the cable of all kinds of pipelines, the slit through walls fireproof blocking of ventilator trunk.
Background technology:
Existing fireproof blocking adopts organic fire prevention calking and inorganic fire cement mostly.Organic putty bans use of in some occasions to the environmental requirement strictness owing to contain toxic volatile matter; Though inorganic fire cement nontoxicity, but become hard block at the shutoff after fixing that finishes, do not have and uphold and the elasticity of compression, can't compensate the mechanical shift that mechanical pipeline vibrations and building settlement cause, and object through walls such as pipeline and cable needs with gravity plug is pounded out when maintenance and replacing, very easily damage peripheral body of wall, the maintenance of pipeline and cable is inconvenience very.
Summary of the invention:
The technical issues that need to address of the present invention provide a kind of poisonous oxious component that do not contain, and fire resistance is arranged, the extension and the elasticity of compression are arranged, can compensate mechanical pipeline vibrations and building settlement and the displacement that causes, the fire prevention calking of being convenient to pipeline or cable maintenance.
The present invention includes and adopt silicone oil, silica gel, color additives, strengthening agent, constitution controller, fire retardant, catalyzer, solvent, it is characterized in that by the synthetic basic glue of silica gel, silicone oil, strengthening agent, constitution controller and solvent; To form elastic foamed body with uniform mixing postcure in 1: 1 foaming by the thick body glue of basic glue, silicone oil and color additives synthetic black even and by basic glue, silicone oil, fire retardant, catalyzer, the even thick body glue of solvent synthetic white during use.
Fire prevention calking foams inclusion-free of the present invention, flawless, no obvious gross porosity, it is good to uphold performance, the elasticity of compression, toughness, watertightness resistance to air loss, has heat insulation, fire-resistant oxygenizement, can compensate the mechanical shift that mechanical pipeline vibrations and building settlement cause, sealing characteristics is good, and multiple metal and non-gold copper-base alloy are all had good adhesiveproperties, and non-corrosiveness, do not contain poisonous oxious component, toxigenicity gas not is to personnel safety.
