Fireproofing heat-insulating door with porous cement structure and manufacturing method thereof

Abstract

The present invention provides a fireproofing heat-insulating door with a porous cement structure and a manufacturing method thereof. The fireproofing heat-insulating door mainly comprises a first plate layer, a second plate layer and a foaming cement layer. The foaming cement layer is arranged between the first plate layer and the second plate layer, and includes a plurality of chambers. A layer of film is formed on the surface of each chamber, and the interior of each chamber is filled with gas. The manufacturing method of the door includes: mixing a foaming agent, methylcellulose and water to obtain a foaming liquid; mixing raw cement material with water to obtain cement paste; mixing the foaming liquid and the cement paste to obtain foaming cement paste; pouring the foaming cement paste into the space between the first plate layer and the second plate layer; curing the foaming cement plate to form the foaming cement player; and fixing and combining the first plate layer, the second plate layer and the foaming cement layer. According to the present invention, the foaming cement layer includes a plurality of chambers, and all the chambers are filled with gas, so that the foaming cement layer has the light-weight, fireproofing and heat insulating effects, and can effectively blocking flames when a fire breaks out, thereby preventing the fire from spreading rapidly.

Description

technical field [0001] The invention relates to a fire-proof and heat-insulating door with a porous cement structure, in particular to a fire-proof and heat-insulating door with a porous cement structure in which a foamed cement layer is arranged between two board layers. The invention also relates to a manufacturing method for improving the fireproof and insulating door with porous cement structure. Background technique [0002] According to the statistical analysis of the Fire Department of the Ministry of the Interior of Taiwan, China in 2012, the number of fires in 2012 was 1,574, resulting in 142 deaths and property losses as high as 694.409 million yuan, and nearly 80% of the cases came from buildings. It can be seen that the fire protection design of buildings and the purchase of fire protection equipment are closely related to everyone's life and property. How to prevent fires from happening or prevent the rapid growth of fires and effectively improve living safety i...

[0002]According to the statistical analysis of fires in 2012 by the Fire Department of the Ministry of the Interior of Taiwan, China, it was pointed out that the number of fires in 2012 was 1,574, resulting in 142 deaths and property losses as high as 6 94.409 million, and nearly 80% of the cases come from building fires. It can be seen that the fire protection design of buildings and the purchase of fire protection equipment are everywhere related to everyone's life and property. How to prevent fires or Preventing the rapid growth of the fire and effectively improving living safety is a major issue for the construction industry. Generally speaking, when a fire occurs, in order to avoid the rapid spread of the fire and affect the evacuation of the crowd, the doors at the entrance and exit are usually replaced. Fire doors with fireproof effects are used to prevent the fire from spreading, but fire doors usually have disadvantages such as heavy weight and high price, which makes fire doors not accepted by the general public. However, some inventors have improved the weight and materials of fire doors. To design a fire door with light weight and fireproof effect, please refer to China Taiwan Patent No. M448557 "combined structure of fire door panel and inner lining material", which is mainly composed of two door panels and an inner lining material, of which , the lining material includes a heat insulating material (fireproof foam or gypsum board or calcium silicate board), and is pasted and fixed in a storage space in the center of the two door panels with joint glue, so that the door panels have better heat insulation and Good combined strength, although the existing technology can achieve the purpose of light fire doors, but the strength of the heat insulation material is poor, and it may cause structural damage after a period of use. When exposed to a fire source, it may emit toxic substances due to high temperature, which is harmful to human health. Therefore, how to provide high-strength door panels with fire-proof and heat-insulating effects, and avoid the use of joint glue to improve the safety of use is an issue. problem to be solved
