Abstract
The invention discloses a fireproof flame-retardant rigid polyurethane foam plugging material which consists of a component A and a component B, wherein the component A comprises 20-40 parts of rigid foam polyether polyol, 25-55 parts of a composite flame retardant, 0.1-1 part of a catalyst, 0.1-2 parts of a foam stabilizer, 0.05-1.2 parts of a foaming agent and 5 parts of a dye; the component B is 25-50 parts of polyisocyanate, the component A and the component B are mixed during construction, the rigid polyurethane foam plugging material with the fireproof and flame-retardant functions is provided, the high temperature resistance of the polyurethane fireproof plugging material is improved by adding ceramic fiber powder, and the framework supporting effect is achieved after combustion, so that combustion products are not easy to collapse, toxic gas and smoke are effectively blocked, the flame retardant effect of the polyurethane fireproof plugging material is further improved by the synergistic effect of the composite flame retardant, and open flame combustion is not easy to occur; the addition of the ceramic fiber powder can reduce the heat conductivity coefficient of the polyurethane fireproof plugging material, and the plugging material with better heat insulation performance is obtained.
Description
Technical Field
The invention belongs to the field of building chemical materials, and particularly relates to a fireproof flame-retardant rigid polyurethane foam plugging material.
Background
In recent years, fire disasters caused by construction sites and building materials tend to be frequent in China, and extra-large fire disasters in many areas are related to the building materials, so that great loss is caused, and the fire prevention of the building materials is particularly important. The building fire protection system is divided into an active fire protection system and a passive fire protection system, wherein the active fire protection system consists of automatic (manual) control alarm, spraying, fire protection electricity utilization, water supply and other equipment systems; the passive fire protection system is composed of fire-resistant or non-combustible decoration materials, such as fire-resistant doors, fire-resistant suspended ceilings, and fire-resistant plugging materials such as cables, pipelines and the like which penetrate through holes formed in walls and floors and building gaps.
The fireproof plugging material generally refers to a material which is used for a cable bridge, a conduit, various pipelines and the like to penetrate through a hole formed in a wall or a floor slab or gaps and the like caused by some reasons in the process of building construction and has the functions of heat insulation, fire prevention, flame retardance and smoke prevention. The fireproof plugging material is widely applied, and almost all buildings are made of the fireproof plugging material, in particular to buildings and important public buildings in the industries of electric power, petrifaction, transportation, metallurgy, communication and the like.
At present, domestic fireproof plugging materials mainly comprise a fire retardant bag, inorganic plugging materials and organic plugging materials, but the materials have some defects and drawbacks. The fire retardant package can not achieve the smoke-tight effect, the air tightness requirement can not be met in some special industries, and the construction is difficult to control; the inorganic blocking material is easy to crack and inconvenient to construct; the organic blocking material can corrode a matrix after long-term use, and fire hazard is easily formed. Therefore, in order to overcome the defects of the fireproof plugging material, a novel material is urgently needed to replace the fireproof plugging material, and the polyurethane fireproof plugging material is convenient to apply. The invention patent CN101003611A provides a novel high-efficiency fireproof plugging material, a bi-component foaming system and a product thereof, which have good flame retardant effect; the invention patent CN105255153A utilizes polyurethane, polyether glycol, microlite and the like to prepare an anticorrosion fireproof polyurethane foam joint filling material, and the material has a plurality of components and excellent anticorrosion and fireproof performances; the invention patent CN103183806B discloses a bi-component high-flame-retardant rigid polyurethane foam material, which has excellent mechanical property, high flame-retardant property and durable storage property and is suitable for buildings with higher fireproof level. The invention patent CN101298515A discloses a preparation and application method of a polyurethane fireproof blocking material, wherein the polyurethane fireproof blocking material is prepared by carrying out chemical reaction on polyisocyanate containing a flame retardant and polyether polyol.
