Problems solved by technology

However, the lack of skeleton support after foaming leads to poor structural stability after foaming and easy deformation and damage
At the same time, due to the addition of other raw materials, the composition is relatively complex, which has buried hidden dangers for the phenomenon of frost and halogen

Embodiment 1

[0049] Such as figure 1 with figure 2 As shown, the new inorganic fire door consists of an upper panel layer 1, a lower panel layer 2 and an intermediate sandwich layer 3 sandwiched between the upper panel layer 1 and the lower panel layer 2. The intermediate sandwich layer 3 includes a square frame-shaped The wooden frame 31 and the filling material 32 filled in the middle gap of the wooden frame 31.

[0050] Both the upper panel layer 1 and the lower panel layer 2 are formed by alternate bonding of multiple layers of non-alkali glass fiber mesh cloth 4 and magnesite mixed slurry 5, and the alkali-free glass fiber mesh cloth 4 in the lower panel layer 2 The edge is extended around and rolled upwards, and the frame part of the wooden frame 31 is rolled up to form the cladding layer 4a, and the packing material 32 is tightly filled to tightly squeeze the cladding layer 4a located inside the frame on the frame.

[0051] The manufacture method of above-mentioned novel inorgani...

Embodiment 2

[0066] The structure of the fire door to be prepared in this embodiment is the same as that in Embodiment 1.

[0067] The manufacture method of above-mentioned novel inorganic fireproof door comprises the steps:

[0068] Step 1, prepare the magnesium chloride aqueous solution of 22 degrees Baume;

[0069] Step 2, preparing magnesium chloride cement slurry: uniformly mixing magnesium oxide and magnesium chloride aqueous solution, the weight-number ratio of magnesium oxide and magnesium chloride aqueous solution is 0.5:1;

[0070] Step 3, preparation of modifying agent, modifying agent is made up of following composition and proportion (parts by weight): barium silicate 2, sodium silicate 3.5, polymer waterproof rubber powder 20, construction gypsum 311.5, bentonite 140, mica powder 60, lithium silicate 2.5, polyvinyl alcohol 8, flocculant 2.5, talcum powder 150, pozzolan 300;

[0071] Step 4, prepare mixed slurry: add modifier to the magnesium chloride cement slurry, stir unt...

Abstract

The invention provides a novel inorganic fireproof door and a manufacturing method thereof, belonging to the technical field of magnesite products and solving the problems of poor structural stability and easiness of frost and halogenation return phenomena of the traditional inorganic fireproof doors. The novel inorganic fireproof door comprises an upper plate layer, a lower plate layer and a middle sandwich layer, wherein the middle sandwich layer comprises a wood frame and a filler filled in a gap of the wood frame. The fireproof door can be manufactured through the following steps of: (1) preparing a magnesium chloride aqueous solution; (2) preparing magnesium-chloride cement slurry; (3) preparing a modifying agent; (4) preparing mixed slurry; (5) preparing the filler; (6) manufacturing the lower plate layer; (7) placing the wood frame; (8) rolling rims; (9) filling; (10) manufacturing the upper plate layer; (11) closing molds; (12) pressing dies; and (13) curing and then demolding. The fireproof door and the manufacturing method thereof which are disclosed by the invention can be used for saving a large quantity of natural wood and are beneficial to protecting the natural environment, and the product has the advantages of aging resistance, high firmness and difficult deformation.

Description

technical field [0001] The invention belongs to the technical field of magnesite products, and relates to a novel inorganic fireproof door and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, residential and office doors are becoming more and more exquisite, and the taste is constantly improving. However, the price of luxury solid wood doors and oak doors is too high. Real wood doors consume too much wood. Extensive use will cause the depletion of forest resources and the deterioration of the ecological environment, which does not conform to the national industrial policy. The disadvantages of easy moth and short service life. [0003] For this reason, a new type of composite door with magnesite as raw material came into being. The door uses magnesium oxide and magnesium chloride as the main raw materials, and after adding ingredients and modifiers, i...
