Fire doors are mainly divided into five types in terms of materials: steel, steel-wood structure, stainless steel, aluminum alloy and copper. Youxing Shark focuses on the innovative research and development of environmentally friendly flame-retardant materials for fire doors. The products have strong bonding performance and can bond aluminum silicate wool, rock wool, perlite fireproof board, vermiculite fireproof board, and metal , Ceramics and other materials and steel plates and other metals; if sprayed and heated, it will not affect the strength of the adhesive layer.

Fireproof board is also called refractory board, and its scientific name is thermosetting resin impregnated paper high pressure laminated board. The English abbreviation is HPL (Decorative High-pressure Laminate). It is a refractory building material for surface decoration. It has rich surface colors, textures and special physical properties. Fireproof boards are widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. The fireproof board is a refractory building material for surface decoration. The fireproof board is made of base paper (titanium powder paper, kraft paper) through the melamine and phenolic resin impregnation process and high temperature and high pressure environment.

1. Mineral wool board and glass wool board:

mainly use mineral wool and glass wool as heat insulation materials. It is non-combustible, good in high temperature resistance, and light in weight, but its shortcomings are:

① short fibers can cause harm to the human respiratory system;

② poor strength of the board;

③ poor barrier performance of the board to the spread of fire smoke;

④ poor decoration.

⑤ The installation and construction workload is large.

Therefore, most of this kind of board has evolved into a board with inorganic bonding material as the base material and mineral wool and glass wool as the reinforcing material.

2. Cement board:

Cement board has high strength and a wide range of sources. In the past, it was often used as a fireproof ceiling and partition wall, but its fire resistance performance was poor, and it was easy to burst and perforate in the fire field and lose its protective effect, which limited its application. Cement concrete components have good heat insulation and sound insulation performance, and can be used as partition walls and roof panels. Improved varieties such as fiber-reinforced cement boards have appeared in the building materials market one after another, which have the advantages of high strength and good fire resistance, but poor toughness, high alkalinity, and poor decorative effects.

3. Perlite board, floating bead board, vermiculite board:

a hollow board made of low-alkalinity cement as the base material, perlite, glass beads, and vermiculite as aerated filling materials, and adding some additives to compound. . It has the characteristics of light weight, high strength, good toughness, fire protection and heat insulation, and convenient construction. It can be widely used in non-load-bearing parts such as sub-rooms, households, bathrooms, kitchens, and communication pipes of high-rise frame buildings.

4. Fireproof gypsum board:

Since the fireproof performance of gypsum has been widely accepted, the fireproof board with gypsum as the base material has developed rapidly. The main components of the board are non-combustible and contain crystal water, and have good fire resistance. It can be used as partition walls, suspended ceilings and roof panels. The material source of the board is abundant, which is convenient for the factory-shaped production. In use, it has a lighter self-weight, which can reduce the load-bearing capacity of the building, is easy to process, can be sawed and planed, is easy to construct, and has good decorative properties, but its flexural performance is poor. There are many factors that affect the fire resistance of gypsum board, such as composition, board type, keel type, board thickness, whether there is filler in the air layer, and the assembly method. In recent years, new varieties such as silica-calcium gypsum fiberboard and double-sided sticker gypsum fireproof board have appeared.

5. Calcium silicate fiberboard:

It is a building board with lime, silicate and inorganic fiber reinforced materials as the main raw materials. It has the characteristics of light weight, high strength, heat insulation, good durability, excellent processing performance and construction performance, etc. It is mainly used to make ceilings, partition walls, and as fire protection materials for steel columns and steel beams. However, the strength and bending performance of the sheet need to be improved.

6. Magnesium oxychloride fireproof board:

It belongs to magnesium oxychloride cement products. It is composited with magnesia cementing material as the main body, glass fiber cloth as the reinforcing material, and light insulation material as the filler, which can meet the non-combustibility requirements. A new type of environmentally friendly board.

Product Features


High bonding

The unit bonding surface bears high bonding force, and the cohesive strength of the adhesive layer and the bonding strength between the adhesive layer and the bonded surface are high. It can ensure that the board will not crack and degummed after bonding.


Can bond a variety of
fireproof materials

It is suitable for the sandwich compound of inorganic board, rock wool, polystyrene board, metal and other materials, with stable quality.


Excellent filling

It has a certain filling effect on core materials with poor porosity and low flatness.


High temperature
baking varnish

Can withstand the temperature of 180-230 degrees Celsius, high-temperature baking paint 25-60 minutes without degumming, suitable for high-temperature drying room and automatic line baking paint.

Operation Specification

STEP 01 The surface of substrate should be flat and clean.

Flatness standard: +0.1mm surface must be clean, oil-free, dry and water-free.

STEP 02 The ratio of adhesive is critical.

The supporting roles of the main agent (off-white) and curing agent (dark brown) are executed in corresponding proportions, such as 100:25, 100:20

STEP 03 Stir the glue evenly

After mixing the main agent and the curing agent, stir evenly quickly, and use a stirrer to repeatedly pick up the gel 3-5 times without silky brown liquid. The mixed glue will be used up within 20 minutes in summer and 35 minutes in winter

STEP 04 Standard of the amount

(1) 200-350 grams (materials with smooth interlayer: such as inorganic boards, foam boards, etc.)

(2) 300-500 grams for delivery (materials with interlayer porous: such as rock wool, honeycomb and other materials)

STEP 05 Sufficient pressurization time

The glued board should be compounded within 5-8 minutes and pressurized within 40-60 minutes. The pressurization time is 4-6 hours in summer and 6-10 hours in winter. Before the pressure is relieved, the adhesive should be basically cured

STEP 06 Sufficient compression strength

Pressure requirement: 80-150kg/m², the pressure must be balanced.

STEP 07 Set aside for a while after decompression

The curing temperature is above 20℃, and it can be processed lightly after 24 hours, and can be processed deeply after 72 hours.

STEP 08 Gluing equipment should be washed frequently

After the glue is used up every day, please clean it with dichloromethane, acetone, thinner and other solvents to avoid clogging of the glued teeth and affect the amount of glue and the uniformity of the glue.
