Fireproof Sandwich Panel.jpg

The fire door is made of fire retardant material with fire resistance stability, integrity and heat insulation. It is mainly used for firewall opening of building fire partition, stairwell entrance, evacuation walkway, pipe wellhead, etc. Personnel pass through to prevent the spread of flame and prevent the flow of combustion fumes in the event of a fire, and to seal when the air supply system is working. In today's increasingly mature fire-fighting technology, buildings with fire protection requirements have fire-proof doors. At present, most fire protection design codes in China clearly require fire doors. The development, development and production of fire door products have played a positive role in ensuring the safety of people's lives and property. The existing fireproof materials are mainly perlite plates. Although the fireproof performance is good, the strength is very poor. And the damage rate during installation is more than 30%, which not only increases the cost of use, but also its fragile defects affect the fireproof, thermal insulation and sound insulation effects of the board.

 

 

Technical realization elements:

It is an object of the present invention to provide a fire door sandwich panel material that addresses the above technical deficiencies.

To achieve the above object, the present invention provides the following technical solutions:

The utility model relates to a fire door sandwich board material, which is composed of the following raw materials according to the weight: 30-40 parts of perlite, 26-30 parts of magnesium oxychloride cement, 3-5 parts of lithium tetraborate, 14-22 parts of bentonite, and 10-. 14 parts, 30-45 parts of calamine, 10-15 parts of calcite, 3-4 parts of basalt fiber and 10-20 parts of polypropylene fiber.

The above fire door sandwich panel material is composed of the following raw materials according to the weight: 30-38 parts of perlite, 26-30 parts of magnesium oxychloride cement, 3-5 parts of lithium tetraborate, 14-20 parts of bentonite, magnesium sulfate 10 - 13 parts, 30-43 parts of calamine, 10-14 parts of calcite, 3-4 parts of basalt fiber and 10-18 parts of polypropylene fiber.

The above fire door sandwich panel material is composed of the following raw materials in parts by weight: 35 parts of perlite, 28 parts of magnesium oxychloride cement, 4 parts of lithium tetraborate, 18 parts of bentonite, 12 parts of magnesium sulfate, 38 parts of calamine, 13 calcite, 3 parts of basalt fiber and 15 parts of polypropylene fiber.

Compared with the prior art, the beneficial effects of the present invention are:

The material of the fire door core board made of the fire door sandwich board material has good performance indexes such as compression resistance, bending resistance and fire resistance, and does not decompose and expand after contact with water, thereby greatly improving the fire prevention. The performance of the door widens its range of use.

Detailed ways

The technical solutions of the present patent are further described in detail below in conjunction with specific embodiments.

Example 1
