Abstract

The invention provides a fireproof adhesive, which is prepared from the following raw materials: liquid sodium silicate, silica sol, polyvinyl alcohol, a defoaming agent, heat absorption powder, expansion powder, a dispersing agent, a wetting agent and fibers. The inorganic-organic composite fireproof adhesive provided by the invention can be used for well bonding a metal foil surface and inorganic core materials, has relatively strong bonding force, remarkably reduces the content of organic matters in the whole product, has the performance of releasing crystal water to reduce space temperature and thermal expansion, and can greatly improve the comprehensive fireproof capability of the product. The fireproof adhesive provided by the invention not only can be applied to fire prevention in the power industry, but also can be applied to fireproof materials needing to be covered with metal foils in other industries, and has a wide application range. The invention also provides a preparation method of the fireproof adhesive.

Description

technical field

[0001] The invention belongs to the technical field of fireproof materials, and in particular relates to a fireproof glue and a preparation method thereof. Background technique

[0002] Key fire protection parts of the power grid: fire prevention and explosion protection at the intermediate joints of cable trenches and cable tunnels, and fire protection of cable trenches and cable tunnel firewalls. The explosion of the cable intermediate joints caused a fire accident and accounted for a large proportion of cable fires. Cable joints have series ductility after explosion and fire, and the fire consequences are serious. Especially in high-risk places in production areas such as nuclear power, thermal power generation, power transmission and transformation, and petroleum and petrochemical industries, the fire protection of some important circuits and cable intermediate joints is highly protected. Pay attention to.

[0003] At present, developed countries genera...
