依據內政部消防署發佈之統計結果顯示，民國96至100年間最常發生火災的地點以建築物居冠，其次為車輛；且其統計結果依據不同建築物的性質分類又以住宅區的次數最多；且民國100年因火災而造成的財物損失更高達5.5億。 According to the statistics released by the Fire Department of the Ministry of the Interior, the most common fires occurred in the Republic of China in the period of 96 to 100 years, with buildings ranking the second, followed by vehicles; and the statistical results were classified according to the nature of different buildings and the number of residential areas; Moreover, the property damage caused by the fire in the Republic of China in the 100 years was as high as 550 million.
是以，如何發展一種良好的防火塗料，並利用此防火塗料保護建築物表面，藉此有效降低火勢蔓延的速度及火災造成的傷亡嚴重性，甚而減少火災發生的次數便成為目前十分重要之課題。 Therefore, how to develop a good fireproof coating and use this fireproof coating to protect the surface of the building, thereby effectively reducing the speed of fire spread and the seriousness of fire and death caused by fire, and even reducing the number of fires has become an important issue at present. .
市面上常見的防火塗料為有機防火塗料或有機/無機防火塗料，其防火塗料中多半以有機黏結劑(如：聚氨酯、有機矽氧烷、環氧樹脂、酚醛樹脂等)為基底，另添加有機難燃劑、有機分散劑、顏料等助劑，利用防火塗料受熱燃燒後所生成的氧化物作為隔絕層，以提供所需之防火與阻燃效果。 The common fireproof coatings on the market are organic fireproof coatings or organic/inorganic fireproof coatings. Most of the fireproof coatings are based on organic binders (such as polyurethane, organic siloxane, epoxy resin, phenolic resin, etc.). Auxiliary agents such as flame retardants, organic dispersants, pigments, etc., use the oxides formed by the fire-retardant coatings to be used as insulation layers to provide the desired fire and flame retardant effects.
然而，以傳統有機防火塗料為例，其因含有一定含量以上之有機物質而具有下列幾項缺點：(1)有機物質有助於黴菌滋生，而使基板(如：牆壁)發霉；(2)有機物質(如：甲醛、甲苯、苯酚等)受熱燃燒後易釋放毒性氣體，並且產生大量濃煙；(3)易老化問題。 However, traditional organic fireproof coatings, for example, contain a certain amount of organic substances and have the following disadvantages: (1) organic substances contribute to mold growth, and substrates (such as walls) are mildewed; (2) Organic substances (such as: formaldehyde, toluene, phenol, etc.) are susceptible to release of toxic gases after combustion by heat, and produce a large amount of smoke; (3) aging problems.

依據本發明，所述之無機矽酸鹽防火塗料主要是於空氣中透過碳化反應使矽膠含量增加，再藉由自由水分子的蒸發和矽膠脫水成固體二氧化矽，而凝結硬化，藉以形成透明性無機矽酸鹽防火保護層，其碳化反應式係如下所示：M2O‧nSiO2+CO2+mH2O → M2CO3+nSiO2‧mH2O According to the present invention, the inorganic bismuth fire retardant coating mainly increases the content of tannin by carbonization reaction in the air, and then dehydrates into solid cerium oxide by evaporation of free water molecules, thereby coagulating and hardening, thereby forming a transparent inorganic silicate fire protection layer, based carbonization reaction formula as follows: M 2 O‧nSiO 2 + CO 2 + mH 2 O → M 2 CO 3 + nSiO 2 ‧mH 2 O
於此，由於空氣中所含之二氧化碳濃度低，使無機矽酸鹽防火塗料進行碳化反應及凝結固化反應之過程緩慢，故能有利於搭配進行其他加工處理。 Herein, since the concentration of carbon dioxide contained in the air is low, the process of carbonization reaction and coagulation and solidification reaction of the inorganic antimonate fireproof coating is slow, so that it can be favorably matched with other processing.
較佳的，當無機矽酸鹽防火塗料之金屬氧化物(M2O)為一氧化二鈉(Na2O)，即，無機矽酸鹽防火塗料之主成分為Na2O‧nSiO2時，形成於基板上之無機矽酸鹽防火保護層包含碳酸鈉(Na2CO3)及SiO2‧H2O。 Preferably, when the metal oxide (M 2 O) of the inorganic bismuth fire retardant coating is sodium oxynitride (Na 2 O), that is, the main component of the inorganic bismuth fire retardant coating is Na 2 O‧nSiO 2 The inorganic antimonate fireproof protective layer formed on the substrate comprises sodium carbonate (Na 2 CO 3 ) and SiO 2 ‧ H 2 O.

依據本發明之一實施態樣，當形成在基板上的無機矽酸鹽防火保護層受熱時，其結晶水與OH基脫水產生水氣，使外層交聯的矽酸鈉、矽酸鉀或矽酸鋰受熱後膨脹產生空氣簾。所述之空氣簾係由複數個白色密閉氣室所組 成，由於各個密閉氣室皆係處於半真空狀態，故本發明之無機矽酸鹽防火保護層可藉由該等密閉氣室阻止氧氣傳遞(即，避免可燃物與空氣接觸)，藉此達到良好的防火與阻燃效果。 According to an embodiment of the present invention, when the inorganic bismuth fire-retardant protective layer formed on the substrate is heated, the crystallization water and the OH group are dehydrated to generate moisture, and the outer layer is cross-linked with sodium citrate, potassium citrate or strontium.

Therefore, since each of the sealed gas chambers is in a semi-vacuum state, the inorganic tantalate fireproof protective layer of the present invention can prevent oxygen transmission (ie, avoid contact of combustibles with air) by the closed air chambers. Good fire and flame retardant effect.
此外，由於本發明之無機矽酸鹽防火保護層受熱後會瞬間膨脹為原有體積之數十倍至數百倍，故所形成之空氣簾更能阻絕火災發生時熱傳導的連鎖反應，避免熱源由無機矽酸鹽防火保護層傳導至基板，甚而避免熱源傳導至基板相對於無機矽酸鹽防火保護層的另一表面，藉此達到良好的防火與阻燃效果。 In addition, since the inorganic bismuth fire-retardant protective layer of the present invention instantaneously expands to tens to hundreds of times the original volume after being heated, the formed air curtain can further block the chain reaction of heat conduction at the time of fire and avoid the heat source. Conducted by the inorganic bismuth silicate fire protection layer to the substrate, and even the heat source is prevented from being conducted to the other surface of the substrate relative to the inorganic bismuth silicate protective layer, thereby achieving good fire and flame retardant effects.
