Abstract

The invention discloses a fireproof silicone foam material and a preparation method of the fireproof silicone foam material. The fireproof silicone foam material is composed of a component A and a component B, wherein the component A and the component B are mixed according to volume ratio of 1: 1 to generate foams after being cured at 15-40 DEG C; the component A is composed of hydroxyl-terminated polysiloxane, dyhydroxyl-terminated polysiloxane, amino-polysiloxane, dimethyl polysiloxane, hydrosilicone oil, reinforcing filler and fire retardant according to a certain proportion; the component B is composed of hydroxyl-terminated polysiloxane, dyhydroxyl-terminated polysiloxane, amino-polysiloxane, dimethyl polysiloxane, platinum group catalyst, fire retardant and black pigment according to a certain proportion. The fireproof silicone foam material not only has good flame retardation, but also has good mechanical property such as tensibility and compression elasticity, does not produce toxic gas when meeting fire, can be widely applied to plugging structures with high fireproof requirements such as mechanical pipes, cables and the like.

Description

technical field [0001] The invention relates to a fireproof silicone foam material and a preparation method thereof, belonging to the technical field of polymer fireproof materials. Background technique [0002] Most of the existing fireproofing blockages use organic fireproofing materials and fireproofing plaster. Organic fireproof blockage will volatilize toxic gas in case of fire; while fireproof plaster is non-toxic, but it forms a hard block after curing, has no stretching and compression elasticity, and cannot compensate for mechanical displacement caused by mechanical pipeline vibration and building settlement , and it is extremely inconvenient for maintenance and replacement of wall-penetrating objects such as pipes and cables. Contents of the invention [0003] In view of the above-mentioned problems and demands in the prior art, the object of the present invention is to provide a fireproof silicone foam material and its preparation method, which will not produce...
