Problems solved by technology

The main problems of fire retardant coatings are poor durability and fire resistance, weak adhesion and easy to fall off, poor ability to resist mechanical shock, collision and wear, and difficult maintenance and management.
The currently used fireproof boards include hard silicon calcium boards, magnesium oxychloride fireproof boards, fireproof gypsum boards and other boards with fireproof and heat-resistant properties. The disadvantages are that they are heavy, and the fire resistance needs to be further improved.

preparation example Construction

[0030] In the preparation process of the above laminated composite fireproof protection board, the substrate, the flame retardant sealing strip and the decorative board are first assembled into a cavity, and then the fireproof glue is filled in the cavity. After curing, the fireproof glue is combined with the substrate and the decorative board Bonded into one body to form a laminated composite fire protection board. The curing temperature is 20-100° C., and the time is 1-24 hours. More specifically, the curing temperature is 30-80° C., and the time is 2-18 hours.

[0031] This application provides a laminated composite fireproof protection board, which uses fireproof glue, a substrate with fireproof function, a decorative board and a flame-retardant sealing strip to construct a laminated composite fireproof board, which is not only a further improvement on the basis of traditional fireproof boards The fire-resistant and heat-resistant performance is improved, and the quality p...

Embodiment 1

[0036] First, assemble the hard calcium silicate board, the flame retardant sealing strip and the decorative metal aluminum board into a cavity;

[0037]Add glycerin and polyethylene glycol to the silica sol containing aluminum and magnesium salts with a water content of 30%, with a mass ratio of 15:2:2, stir at a temperature of 40°C at a speed of 10r / s for 20min; then add epoxy Propane (the mass ratio of propylene oxide to glycerin is 1:1), stirred at 40°C for 50 minutes; then the above mixed solution was lowered to room temperature, and the obtained liquid was fireproof glue;

[0038] Fill the fireproof glue into the cavity assembled by hard calcium silicate board, flame retardant sealing strip and metal aluminum plate with decorative effect; the thickness of the selected hard calcium silicate board is 8mm, the thickness of fireproof glue is 5mm, and the flame retardant sealing strip The rubber material is dense rubber, the cross section of the flame retardant sealing strip ...

Embodiment 2

[0042] First, assemble the hard calcium silicate fireproof board, flame-retardant sealing strip and metal aluminum plate with decorative effect into a cavity;

[0043] The fireproof glue prepared in Example 1 is poured into the cavity assembled by hard calcium silicate fireproof board, flame retardant sealing strip and metal aluminum plate with decorative effect; wherein the thickness of hard calcium silicate board is 10mm, and the thickness of the flame retardant sealing strip is The rubber material is dense rubber, the section of the flame-retardant sealing rubber strip is sheet-shaped, the thickness of the fire-resistant rubber is 6mm, and the thickness of the galvanized plate is 1mm.

[0044] For the multi-layer fire protection board prepared in Example 2 of the present invention, after the fire resistance test, the fire resistance time of the product is 4h; the surface density is about 16.9Kg / m 2 .

Abstract

The invention provides a laminated composite fireproof protection plate. The laminated composite fireproof protection plate consists of a base plate, a decorative plate, a flame-retardant sealing rubber strip and fireproof glue, wherein the base plate, the decorative plate and the flame-retardant sealing rubber strip are assembled to form a cavity, and the cavity is filled with anti-skid glue. According to the laminated composite fireproof protection plate, the fireproof glue, the base plate, the decorative plate and the flame-retardant sealing rubber strip are used to construct the laminated composite fireproof plate; the fire resistance and heat resistance are further improved on the basis of a traditional fireproof plate; and in addition, the mass of the fireproof plate in unit area is reduced. The novel laminated composite fireproof plate also overcomes the common defects of poor durability and heat resistance, easy falling, and poor mechanical shock, collision and abrasion resistance capability of the traditional fireproof coating, and can provide fireproof protection for building load-bearing members.

Description

technical field [0001] The invention relates to the technical field of fire prevention and heat insulation, in particular to a laminated composite fire protection board. Background technique [0002] In the event of a fire, the economic loss caused by building damage is often the first, and some even account for more than 80% of the entire fire economic loss. Modern buildings mostly adopt concrete structure, brick-concrete structure and steel structure. Due to the advantages of small size, light weight, convenient construction and fast construction period, the use of steel structures in some long-span buildings and high-rise buildings is on the rise. In order to reduce the economic loss of fire, it is very necessary to protect buildings from fire. The load-bearing structure in a building is the key to maintaining the existence of the building. If the structure is damaged in a fire, it will lead to the collapse and destruction of the building, causing casualties of firefigh...
