Embodiment 1

[0023] Example 1, the existing fire doors have achieved the purpose of fire prevention by adding a fire door core board to the door leaf or coating the surface with fire retardant paint, but the sound insulation effect of this fire door is poor, and it is impossible to achieve fire and sound insulation at the same time.

Embodiment 2

[0024] Example 2, the sound-proof and fireproof coating contains the following components and parts by mass: 34 parts of mineral wool, 18 parts of silica powder, 17 parts of acrylic resin, 12 parts of carbonized fiber, 10 parts of polyurethane emulsion, 19 parts of reinforcing fiber, and 13 parts of expanded perlite parts, 4 parts of silane coupling agent, 10 parts of curing agent.

[0025] The preparation method of the sound-insulating fireproof coating comprises the following steps:

[0026] A. Mix the acrylic resin and polyurethane emulsion, stir and disperse for 18min-25min, until the mixture is uniform;

[0027] B. Add silica powder, mineral wool, carbonized fiber, expanded perlite, and silane coupling agent in turn while stirring, and continue stirring for 50-70 minutes after the addition is complete until completely mixed;

[0028] C. Continue to add reinforcing fiber and curing agent successively under the state of stirring, and adjust its viscosity to obtain sound-pr...

Embodiment 3

[0030] Example 3, the sound-proof and fireproof coating contains the following components and parts by mass: 36 parts of mineral wool, 21 parts of silica powder, 25 parts of acrylic resin, 15 parts of carbonized fiber, 14 parts of polyurethane emulsion, 21 parts of reinforcing fiber, and 14 parts of expanded perlite 6 parts, 6 parts of silane coupling agent, 12 parts of curing agent.

[0031] The preparation method of the sound-insulating fireproof coating comprises the following steps:

[0032] A. Mix the acrylic resin and polyurethane emulsion, stir and disperse for 22min-31min, until the mixture is uniform;

[0033] B. While stirring, add silica powder, mineral wool, carbonized fiber, expanded perlite, and silane coupling agent in turn, and continue stirring for 60-85 minutes after the addition is complete until completely mixed;

[0034] C. Continue to add reinforcing fiber and curing agent successively under the state of stirring, and adjust its viscosity to obtain sound...

Abstract

The invention provides a sound-insulating fireproof door comprising a fireproof door core plate and sound-insulating fireproof coating which is coated on the surface of the fireproof door core plate.The sound-insulating fireproof coating comprises the following components and parts by mass: 32-37 parts of mineral wool, 16-24 parts of silica powder, 15-32 parts of acrylic resin, 10-20 parts of carbonized fiber, 8-17 parts of polyurethane emulsion, 18-22 parts of reinforcing fiber, 12-16 parts of expanded perlite, 3-7 parts of silane coupling agent and 8-14 parts of curing agent. The mineral wool is added in the sound-insulating fireproof coating to achieve the effect of heat preservation and insulation, damping and sound insulation and sound absorption and noise reduction; the coating is enabled to have good insulation property, good dielectric property, high heat resistance and weathering resistance by adding the silica powder; the coating is enabled to have good heat insulation and sound absorption effect by adding the polyurethane emulsion; and the sound-insulating fireproof coating is coated on the surface of the fireproof door core plate so as to improve the fire resistance ofthe door and have good sound insulation effect.

Description

technical field [0001] The invention relates to the field of wood production and processing, in particular to a fireproof door, in particular to a soundproof fireproof door. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] Due to its fireproof characteristics, the existing fire doors cannot achieve the effect of sound insulation, which reduces the user experience. [0004] Mineral wool is short, fluffy fibers made from mineral raw materials. It is non-combustible, non-mildew, a...
