Embodiment 1

[0035] Step 1): First take five steel plates with a thickness of 1cm, and weld them into a cuboid-shaped cavity, leaving one side open, and the internal height of the cavity is 2.5cm;

[0036] Step 2): Use a grinder to grind the inner wall of the cavity to a rough surface with a roughness of 1.4 μm;

[0037] Step 3): Put a layer of waterproof glue on the inner wall of the cavity, and stick glass wool with a thickness of 2.5mm to the inner wall of the cavity to form an insulation layer;

[0038] Step 4): Take another 1cm thick steel plate that can seal the opening of the cavity and perform the same operation from step 2) to step 3);

[0039] Step 5): Prepare the fireproof and heat insulation layer: take 15 parts of black mud powder, 8 parts of polytetrafluoroethylene, 3 parts of compound animal protein foaming agent, 12 parts of phenolic resin, 5 parts of carboxylated nitrile rubber and 1 part of tea soap Put the element into the mixer and stir well to make it evenly mixed to ...

Abstract

The invention discloses a fireproof insulated door and a manufacturing method thereof. The door comprises a metal housing, a fireproof thermal insulated layer in the metal housing, and a thermal insulating layer between the housing and the fireproof thermal insulated layer. The housing is made of steel plates or aluminum alloy boards, and thickness is 1.0 cm to 1.5 cm. The thermal insulating layeris a glass wool layer with thickness of 2.5-3.5 mm. The fireproof thermal insulated layer is formed by uniformly mixing 15-20 parts of black clay powders or slag powders, 8-12 parts of polytetrafluoroethylene, 3-5 parts of compound type animal protein foaming agent, 12-15 parts of phenolic resin, 5-8 parts of flexibilizer, and 1-1.5 parts of tea saponin, and then spontaneous curing. The flexibilizer is one selected from carboxylic acrylonitrile butadiene rubber, liquid nitrile rubber, and polyvinyl butyral. The manufactured fireproof insulated door has good fireproof property from the door housing and the internal materials, and is provided with the thermal insulating layer and a thermal insulating material in the fireproof thermal insulated layer is added, having good thermal insulationeffect. Thus, the fireproof insulated door made by the manufacturing method has good fireproof thermal insulation effect.

Description

technical field [0001] The invention belongs to the field of fire doors, and relates to a fire and heat insulation door and a manufacturing method thereof. Background technique [0002] Due to the continuous improvement of people's safety awareness and fire prevention awareness, various fire protection products emerge in an endless stream in building materials, such as fireproof boards, fireproof doors and windows, etc. are also various. In addition to the function of ordinary doors, fire doors should also have the function of preventing the spread and spread of fire. However, the existing fire doors are unsatisfactory, and there are problems such as high price and poor fireproof effect. [0003] Chinese patent, application number: 201410029043.2 discloses a fire door, including a door panel, and the door panel is filled with inorganic heat-absorbing materials, wherein the inorganic heat-absorbing materials are inorganic materials that can absorb heat and release water vapo...
