Problems solved by technology

[0004] Except for the slight expansion of the fire retardant package and the good expansion of the organic fireproof board, the other products basically do not have significant expansion properties. It is difficult to achieve effective fire sealing effect for bundled cables and high filling rate cable wells
At present, most of the organic fireproof boards on the market are formed by high-temperature vulcanization and pressing of polyurethane materials. Polyurethane itself is flammable, and the flame retardancy is obtained by adding halogen flame retardants. Halogen materials have good flame-retardant effects, but they will release a lot of smoke. These smoke and acid gases can irritate people's eyes and respiratory system; hinder the fire fighting and rescue work of firefighters and rescuers; and can cause corrosion of electrical system switches and other metal objects that cannot be caused by fire alone

Abstract

The invention provides a room temperature vulcanized fireproof elastomer plate and a preparation method thereof. The room temperature vulcanized fireproof elastomer plate is prepared by the following steps: by using an organic silicon macromolecular material as a binder, adding a crosslinking agent, a coupling agent, a catalyst, a flame retardant, magnetic filler, a ceramic auxiliary and other insulating and heat-insulating packing and carrying out compression moulding; and then vulcanizing under a natural condition to obtain the room temperature vulcanized fireproof elastomer plate. The room temperature vulcanized fireproof elastomer plate can be used for plugging large holes of an electric plate cabinet, a cable shaft, a cable bridge and the like, has the characteristics of being good in expansibility, high in strength of expanded carbonized layer, long in fireproof aging, good in gas tightness of smoke, attractive, fire fighting water impact resistant, easy to dilate, long in fireproof service life and the like and is simple in preparation method and convenient to operate.

Description

Technical field: [0001] The invention relates to a room temperature vulcanized fireproof elastomer plate and a preparation method thereof. Background technique: [0002] In a building fire, fire and toxic smoke gases often spread to adjacent houses or other floors through the holes through which cables, wires and various pipes pass, which expands the fire accident and causes serious consequences. At present, fireproof sealing materials are generally used to block various openings at home and abroad to form a passive fireproof system for buildings to prevent the spread of fire and prevent the spread of toxic gases, control the fire within a certain range, reduce the losses caused by fire, and at the same time Reduce the difficulty of fire fighting. [0003] At present, there are three main types of fireproof sealing materials suitable for electrical panel cabinets, cable shafts and joints, openings or holes in buildings: one is fireproof plaster, organic mud, fireproof bag...
