Problems solved by technology

The performance requirements are getting higher and higher, such as the subways under construction in some large and medium-sized cities, the reconstruction and expansion of airports and stadiums, etc. In these important occasions, the requirements for the fire prevention and warning sectors have increased. For this reason, the country has promulgated a new standard GB12955-2008 "Fire Doors", and stipulates that the use of the old standard is delayed until April 30, 2009. The implementation of the new standard is imperative, and the old standard can no longer meet the existing needs to a certain extent.

Embodiment 1

[0043] As shown above, this example will illustrate the various components in the synthetic silica gel and the cloth-faced perlite composite door core board of the present invention, wherein the fireproof adhesive is required to use polymeric silica gel with a content of free formaldehyde ≤ 1g / kg, so when selecting polymeric silica gel, it is necessary to control the weight parts of its main components to be 50 parts by weight of aluminum phosphate, 50 parts of magnesium silicate, 30 parts of sodium silicate, 30 parts of fireproofing agent and 30 parts of inorganic polymer polymerizer, of which all Select the limit minimum value. When the weight part of any component is less than this value, it will affect the fire-bonding effect of the polymerized silicone gel, and affect its fireproof performance at the same time.

[0044] At the same time, in order to ensure that the strength and fireproof performance of the entire fire door meet the requirements of Q / JLD04-2009 and GB 1295...

Embodiment 2

[0046] This embodiment is similar to Example 1, the difference is that in this example, the maximum value of each component in the polymerized silica gel and the maximum value of the raw material of the cloth-covered perlite composite door core board will be selected, when each component When the value exceeds the maximum value, it will seriously affect the structure of its internal components, thereby affecting its adhesiveness, fire resistance and heat resistance and strength; specifically, the main component of the polymeric silica gel is selected as aluminum phosphate in parts by weight 150 parts, 150 parts of magnesium silicate, 40 parts of sodium silicate, 40 parts of fireproofing agent and 40 parts of inorganic polymer polymerizer; 60 parts of powder, 40 parts of fireproof powder and 40 parts of fireproof curing agent.

Embodiment 3

[0048] Example 3 is similar to Examples 1 and 2, except that the main components of the polymeric silica gel selected in this example are (parts by weight) 100 parts of aluminum phosphate, 100 parts of magnesium silicate, and 35 parts of sodium silicate , 35 parts of fire retardant and 35 parts of inorganic polymer polymerizer. Among the components in the polysilica gel, the aluminum phosphate can be selected in any number of 50-150 parts, the magnesium silicate can be selected in any number of 50-150 parts, and the sodium silicate can be selected in 30 parts. - Any number of parts can be selected from 40 parts, any number of parts can be selected from 30-40 parts of fireproofing agent and any number of parts can be selected from 30-40 parts of inorganic polymer polymerizer.

[0049] Similarly, the raw materials of the cloth-covered perlite composite door core board are 55 parts by weight of expanded perlite powder, 35 parts by weight of fireproof powder and 35 parts by weight...

Abstract

The invention discloses a steel thermal insulation fireproof door and belongs to the technical field of building materials. The steel thermal insulation fireproof door comprises a door frame. A fireproof door panel is hinged to the edge of the door frame. A fireproof rubber layer is laid on the rear door panel of the fireproof door panel. A fireproof expansion seal strip is disposed at the joint of the door frame and the fireproof door panel. The steel thermal insulation fireproof door is simple in structure, simple to operate, convenient to use, low in cost, excellent in fireproof performance and suitable for being popularized, fireproof performance of the fireproof door is increased effectively, the fireproof thermal insulation of the fireproof door is not smaller than 1.5h, the fireproof integrity is not smaller than 1.5h, fire spread can be blocked for a long time, and the Q / JLD04-2009 and GB12955-2008 fireproof door requirements are satisfied.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a steel heat-insulating fire door. Background technique [0002] With the country's large-scale infrastructure construction, the demand for fire doors used in buildings is increasing. The performance requirements are getting higher and higher, such as the subways under construction in some large and medium-sized cities, the reconstruction and expansion of airports and stadiums, etc. In these important occasions, the requirements for the fire prevention and warning sectors have increased. For this reason, the country has promulgated a new standard GB12955-2008 "Fire Doors", and stipulates that the use of the old standard is delayed until April 30, 2009. The implementation of the new standard is imperative, and the old standard cannot meet the existing needs to a certain extent. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentio...
