Manufacturing method and process of environment-friendly heat-insulating fire-proof clean door
The invention belongs to the technical field of construction equipment, and specifically relates to a manufacturing method of an environmentally friendly heat-insulating fireproof clean door. In order to meet the needs of the current construction market and improve the thermal insulation (fire door) requirements of fire protection products in public places, combined with the long-term use of fire doors commonly used in the market, the materials are all energy-based, which does not meet the rationality of the national protection of ecological resources, and the fire protection time, grade and completion cannot continuously meet the national fire protection requirements. Moreover, the existing fire doors still have the following shortcomings: the materials are wood, steel and mineral materials, they are all energy-based materials and cannot be regenerated; chemical raw materials are used for spraying and gluing, and odor, dust, and mist increase atmospheric environmental pressure; high costs, increased national investment, and rising housing prices.

The invention belongs to the technical field of construction equipment, and specifically relates to a manufacturing method of an environmentally friendly heat-insulating fireproof clean door. In order to meet the needs of the current construction market and improve the thermal insulation (fire door) requirements of fire protection products in public places, combined with the long-term use of fire doors commonly used in the market, the materials are all energy-based, which does not meet the rationality of the national protection of ecological resources, and the fire protection time, grade and completion cannot continuously meet the national fire protection requirements. Moreover, the existing fire doors still have the following shortcomings: the materials are wood, steel and mineral materials, they are all energy-based materials and cannot be regenerated; chemical raw materials are used for spraying and gluing, and odor, dust, and mist increase atmospheric environmental pressure; high costs, increased national investment, and rising housing prices.
In view of the defects of the prior art, the fire door manufactured by the manufacturing method of the environmentally friendly heat-insulating fire-proof clean door of the present invention has the requirements of low cost, environmental protection, waste utilization, non-toxicity, fire prevention and the like. In line with the national production requirements for the protection of ecological resources, fire prevention time, grade and after completion can meet the national fire protection requirements; The plates used in the heat-insulated fire-proof clean door are recyclable and pollution-free construction waste, renewable, sprayed and glued with environmental protection materials, free of atmospheric environmental protection pressure of smell, dust and fog, low cost, and reduced national investment and rising house prices. In order to solve the above technical problems, the technical solution adopted by the present invention is: a manufacturing method of an environmentally friendly heat-insulating fireproof clean door, including the following steps:
1. Make the heat-insulated and fireproof clean door frame. The manufacturing process of the door frame is as follows:
(1) Peeling: mainly using multiple saws to cut the wood into door frame strips, door frame strips, and fire protection strips;
(2) Flame-retardant drying: Soak the door frame strips, door frame strips, and fireproof slats in the flame-retardant machine for a certain period of time, take them out of the flame-retardant machine after meeting the process requirements, and then dry them;
(3) Forming: Use a polishing machine to polish the door frame strip, door frame strip and fireproof strip;
(4) Roll frame: use the roll frame machine to roll the door frame strip, door frame strip and fire-proof strip out of the door;
(5) Punching: Punching holes at predetermined positions for easy installation;
(6) combination: door frame strip, door frame strip and fire-proof strip are assembled and formed;
(7) Precision cutting code: use a table saw to accurately process the size of the door frame, and use a coding machine to mark the identification code;
(8) Quality inspection and storage: quality inspection of the produced door frame, quality inspection after qualified storage, unqualified door frame repair after quality inspection again after qualified storage;
2. The process of making thermal insulation and fireproof clean door leaves is as follows:
(1) Assemble the door frame: use a cold press to assemble the metal door frame together to form a door leaf;
(2) pouring: cement and fly ash are mixed with a mixer according to a certain proportion and then poured in the door leaf;
(3) Maintenance: The mixture of cement and fly ash poured into the door leaf is dried with a hot air dryer;
(4) Grinding: sanding the door leaf after casting and drying with a sanding machine to ensure that the surface of the door leaf is smooth and free of burrs;
(5) Covering: Cover the door leaf with environmentally friendly materials;(6) Fine cutting and edge sealing: use a table saw to accurately process the size of the door leaf, and use an edge banding machine to seal the four sides of the door leaf;
(7) Quality inspection and warehousing: quality inspection shall be carried out on the made door leaves, and the door leaves shall be put into storage after passing the quality inspection, and the unqualified door leaves shall be put into storage after passing the quality inspection again after being repaired;
3. The process of making thermal insulation and fireproof clean door frame plate is as follows:
(1) Paving: Use a glue roll machine to spread phenolic glue on the board, and then alternately lay a layer of board until the board reaches the specified thickness, and then use a pre-press to form;
(2) Hot-pressing curing: the pre-pressed door frame plate is molded with a hot press, and the phenolic adhesive is cured;
(3) Fine sand: Use a table saw to accurately process the size of the door frame plate, and then use a sanding machine to polish the door frame plate to ensure that the door frame plate is smooth and free of burrs;
(4) Coating: Use a hot press to coat the melamine plate on the door frame plate;
4. Assembling heat-insulated fire-proof clean door: assemble the door frame, door leaf and door frame plate into fire-proof door.
By adopting the above technical scheme, the heat-insulated fire-proof clean door has the following beneficial effects: the fire-proof door manufactured by the manufacturing method of the environment-friendly heat-insulated fire-proof clean door of the present invention has the requirements of low cost, environmental protection, waste utilization, non-toxicity, fire prevention and the like. It meets the production requirements of the national protection of ecological resources, and the fire prevention time, grade and completion can continuously meet the national fire protection requirements; the board used in the present invention is recyclable and pollution-free construction waste, which is renewable; environmentally friendly materials are used for spraying and gluing, and there is no smell, The atmospheric environmental protection pressure of dust and fog is low in cost, thereby reducing national investment and rising housing prices.
