Open The Ideal Door To A Clean Area
The preparation method and process of the anti-mold insulation fire-proof clean door.
Fire door refers to a door that can meet the requirements of fire stability, integrity and heat insulation within a certain period of time. It is a kind of fire-resistant partition wall, which is located in the fire zone, evacuation staircase, shaft and so on. Fire doors not only have the function of ordinary doors, but also have the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of people.

Fire door refers to a door that can meet the requirements of fire stability, integrity and heat insulation within a certain period of time. It is a kind of fire-resistant partition wall, which is located in the fire zone, evacuation staircase, shaft and so on. Fire doors not only have the function of ordinary doors, but also have the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of people. The fire door ensures the safety performance of the home, but the existing fire door structure is simple. Existing fire doors are mainly divided into steel fire doors and wooden fire doors. After long-term use, the wooden fire door is easy to mold due to moisture, which greatly reduces the practicality of the fire door.
The purpose of the skilled person is to provide a mildew-proof, heat-insulating and fireproof clean door and a preparation method thereof, so as to solve the problems raised in the above background art. In order to achieve the above purpose, technicians adopt the following technical scheme: a mildew-proof and heat-insulating fire-proof clean door, including a door core board, polyurethane foam board and mildew-proof coating; The heat-insulating and fire-proof clean door core board includes the following components by mass percentage: 30-40 parts of polyvinyl alcohol, 100-120 parts of sulphoaluminate cement, 3-8 parts of phenolic resin, 5-10 parts of short glass fiber, 15-25 parts of polypropylene fabric and 20 parts of high alumina cement foaming agent; both sides of the surface of the core plate of the heat-insulating fire-proof clean door are bonded with polyurethane foam board through adhesive, and the surface of the polyurethane foam board is coated with mildew-proof coating; the heat-insulating fire-proof clean door mildew-proof coating includes the following components by mass: 50-60 parts of acrylic emulsion, 30-40 parts of water-soluble amino-modified alkyd resin, 30-40 parts of modified diatomite, 10-20 parts of silica powder, 5-20 parts of antibacterial agent, 5-5-5-8-8-8-8. Mildew proofHeat insulation fireproof clean door, including door core board, polyurethane foam board and anti-mold coating; The door core board includes the following components by mass: 32-37 parts of polyvinyl alcohol, 105-115 parts of sulphoaluminate cement, 4-6 parts of phenolic resin, 7-9 parts of short glass fiber, 18-22 parts of polypropylene fabric and 22-26 parts of high alumina cement foaming agent; Both sides of the surface of the heat-insulating fire-proof clean door core board are bonded with polyurethane foam board, and the surface coated with anti-mold coating; the heat-insulating fireproof clean door core board includes the following components by mass percentage: 35 parts of polyvinyl alcohol, 110 parts of sulphoaluminate cement, 5 parts of phenolic resin, 8 parts of short glass fiber yarn, 20 parts of polypropylene fabric and 25 parts of high alumina cement foaming agent; Both sides of the surface of the door core board are bonded with adhesive to polyurethane foam board, and the surface of the polyurethane foam board is coated with mildew-proof coating.
Compared with the existing technology, the above-mentioned insulation fire-resistant clean door has the advantages of strong function, heat insulation and flame retardant, greatly improves the practicality of the fire door and.Heat insulation fireproof clean doorThe anti-mildew coating on the surface has hydrophobic properties, effectively avoids the occurrence of water droplets hanging on the wall, has anti-mildew function, and is easy to use.
