Example Embodiment

[0023] Example 1:

[0024] Take the formed EPS insulation board on the market as the substrate. First, according to the size of the required board, a cavity mold of the corresponding size is made of stainless steel or hard plastic, and the formed EPS insulation board is cut into a certain size. Of plates. Then put the cut EPS board into the mold, and evenly spread the aluminum hydroxide gel flame retardant 2 times its weight on the surface of the EPS insulation board. The aluminum hydroxide gel flame retardant is commercially available. It is gelatinous, so there is no need to re-modulate. Use a vacuum press with a vacuum pressure of 0-0.1Mpa to uniformize the aluminum hydroxide gel flame retardant. Suck into the insulation board and wrap the insulation board. After 12 hours of curing at room temperature, then drying at 50-60 degrees Celsius. After drying, the fire protection rating shall be tested according to GB8624-2006 "Classification of Building Materials and Products' Co...

Example Embodiment

[0033] Example 2:

[0034] Using the EPS insulation board that has been formed on the market as the base plate, the EPS board is perforated with a perforation rate of 100 holes / decimeter square, a hole drill with a diameter of 3mm, and a perforation depth to penetrate the board.

[0035] Mix talc with tris(2-chloroethyl) phosphate and stir for 20 minutes to obtain a paste flame retardant material, wherein the weight of talc is 0.9 times the weight of the substrate, and the weight of tris(2-chloroethyl) phosphate is 1.8 times the weight of the substrate. Fill the prepared paste-like flame-retardant material into the punched holes. Because the flame-retardant is paste-like, the flame-retardant material will not be lost. Then after 12 hours of natural curing at room temperature, and then enter the 50-60 ℃ environment for drying. Then according to GB8624-2006 "Combustion performance classification of building materials and products", the fire protection level project is tested, and t...

[0044] Example 3:

[0045] Take the formed XPS insulation board on the market as the substrate, and cut the board into the required size according to the requirements in advance. The magnesium hydroxide flame retardant is mixed with water and stirred for 20 minutes to obtain a paste flame retardant material, wherein the amount of magnesium hydroxide is twice the weight of the substrate, and the amount of water is the same as the weight of the substrate.

[0046] Use a syringe to suck up the paste-like magnesium hydroxide flame-retardant material to inject the XPS insulation board. The injection frequency is 100 eyes / decimeter square and the needle diameter is 5 mm. After the injection is completed, it will undergo natural curing for 12 hours at room temperature, and then dry it at a temperature of 50-60℃. Then according to GB 8624-2006 "Combustion performance classification of building materials and products", the fire protection rating items are tested, and the requirements are m...

Abstract

The invention discloses a production process of an A2-grade fireproof thermal insulation board. The production process is characterized in that a formed insulation board is used as a substrate, and then a flame retardant material is uniformly sucked into or filled into or injected into the insulation board to obtain the A2-grade fireproof insulation board. According to the production process, an original non-flame-retardant insulation board is converted into an EPS board which can achieve the A2-grade fireproof effect. The using performance of the insulation board is improved to a great extent, and meanwhile, the problem of the presence of the non-flame-retardant insulation boards on the market is solved, so that the insulation board can be better applied to the building field. The production process has relatively wide process applicability and a good flame retardant effect and can meet the A2-grade fireproof grade requirements.

Description

technical field [0001] The invention belongs to a production process of an A2 grade fireproof heat preservation board and belongs to the field of building energy-saving materials. Background technique [0002] Building energy conservation is an important part of energy conservation. With the rapid development of my country's economy, the demand for thermal insulation materials is increasing, especially in the construction field. The demand is immeasurable. At the same time, the requirements for fire protection grades are also getting higher and higher. Non-combustible insulation boards can be applied to various important industries such as construction, petroleum, electric power, metallurgy, textiles, transportation, etc., but only in construction, according to the figures released by the National Bureau of Statistics, the annual investment in real estate development in my country reaches trillions, Non-combustible thermal insulation materials are one of the important buildi...
