Description
本創作係有關於一種具太陽輻射阻隔與防火功能之氣凝膠酚醛發泡板,尤指一種在酚醛發泡板內佈設有複數個氣凝膠顆粒之板材,不僅具有較佳隔熱特性,並具有防火耐燃特性。 The present invention relates to an aerogel phenolic foaming board with solar radiation barrier and fireproof function, in particular to a sheet material in which a plurality of aerogel particles are arranged in a phenolic foaming board, which not only has better heat insulating properties, And has fire and flame resistance.
現有用於建築外殼的隔熱手法大多是於建築外殼表面塗上隔熱塗料,然而此種方法容易因為空氣中的懸浮微粒沉降在屋頂表面,以及屋頂塗料受太陽輻射影響而造成性能劣化,導致屋頂的隔熱效果隨著使用壽命增加而降低。 The existing thermal insulation methods for building outer casings are mostly coated with thermal insulation coating on the surface of the building envelope. However, this method is easy to cause performance degradation due to the deposition of suspended particles in the air on the roof surface and the influence of solar radiation on the roof coating. The insulation effect of the roof decreases as the service life increases.
另外,將隔熱材料放置於屋頂或外牆的內部亦為常見的隔熱方法。舉例而言,中華民國專利公告第M541491號即揭示一種「隔熱屋頂」,主要包括有樓板結構體、排水隔熱層、纖維層,及透水覆蓋層,其中,排水隔熱層包括至少一排水板,以界定出一隔熱空間;所述透水覆蓋層可避免太陽直接照射樓板結構體,隔熱空間內的空氣則能阻隔大部分的熱能傳導至樓板結構體。上述結構雖能達到隔熱效果,但其結構較為複雜。 In addition, placing the insulating material on the inside of the roof or exterior wall is also a common method of insulation. For example, the Republic of China Patent Publication No. M541491 discloses an "insulated roof" comprising a floor structure, a drainage insulation layer, a fiber layer, and a water permeable cover layer, wherein the drainage insulation layer comprises at least one drainage The plate defines a heat insulating space; the water permeable cover layer prevents the sun from directly illuminating the floor structure, and the air in the heat insulating space can block most of the heat energy from being transmitted to the floor structure. Although the above structure can achieve the heat insulation effect, the structure is relatively complicated.
常用的隔熱材料有聚氨酯(Polyurethane,PU)發泡板或是岩棉,例如中華民國專利公告第M453698號之「建物用隔熱板」,即揭示其隔熱板含有利用聚氨酯硬質發泡材製成的一矩形本體。中華民國專利公告第 M301910號之「隔熱材結構改良」,即揭示一種使用於屋頂、牆板上之具組裝施工方便的隔熱材結構,主要由上、下兩鋼板之間設有岩棉材質之隔熱防火層,藉以岩棉及鋼板之特性,及較少之層數的結構,達到隔熱、質輕及節省成本等優點。然而,PU發泡板雖然具有優異的隔熱性能,但是PU發泡板是一種易燃材料。至於岩棉雖然屬於不燃材料,但是其隔熱性能較PU發泡板不佳,且岩棉在實際使用階段,會因為吸收水分而使得隔熱效能變得更差。 Commonly used heat insulating materials are polyurethane (PU) foamed sheets or rock wool. For example, the "insulation board for building construction" of the Republic of China Patent No. M453698, which discloses that the heat insulating board contains polyurethane hard foaming material. A rectangular body made. Republic of China Patent Notice M301910 "Improvement of Heat Insulation Structure" reveals a heat-insulating material structure that is easy to assemble and use on roofs and wall panels. It is mainly composed of rock wool material between the upper and lower steel plates. The layer, by virtue of the characteristics of rock wool and steel plate, and the structure of a small number of layers, achieves the advantages of heat insulation, light weight and cost saving. However, although PU foamed sheets have excellent heat insulating properties, PU foamed sheets are a flammable material. Although rock wool is a non-combustible material, its thermal insulation performance is inferior to that of PU foaming board, and in the actual use stage, rock wool will make the heat insulation performance worse due to moisture absorption.
習知的酚醛發泡板為一種耐燃材料,例如中華民國專利公告第I468293號即揭示一種「具有蜂窩結構之酚醛發泡板」,其係以簡化的製備過程製成內部具有蜂窩平板體的內部中空,使整體板的密度顯著降低,並提昇絕熱性能及耐火性能。然而,一般市面上的酚醛發泡材料大多為耐燃三級或耐燃二級,若是需要提升酚醛發泡板的耐燃特性通常需要另外填加阻燃劑。 A conventional phenolic foamed sheet is a flame-resistant material. For example, the Republic of China Patent Publication No. I468293 discloses a "phenolic foamed sheet having a honeycomb structure" which is formed into a honeycomb interior having a honeycomb body by a simplified preparation process. Hollow, the density of the whole board is significantly reduced, and the thermal insulation performance and fire resistance are improved. However, the general phenolic foaming materials on the market are mostly three-grade flame-resistant or fire-resistant secondary. If it is necessary to improve the flame resistance of the phenolic foamed board, it is usually necessary to additionally add a flame retardant.
緣是,創作人有鑑於現有之隔熱與防火耐燃板於實際實施時產生多處缺失,秉持多年該相關行業之豐富設計開發及實際製作經驗,改良創作一具太陽輻射阻隔與防火功能之氣凝膠酚醛發泡板,其目的在於提供一種具有隔絕太陽輻射功能與耐燃性能之板材;藉此,本創作不僅具有極佳隔熱效用,並具有防火耐燃一級之效用。 The reason is that the creators have created a number of defects in the actual implementation of the existing insulation and fire-resistant flame retardant panels. Based on years of rich experience in design and development and actual production of the relevant industries, the creators have improved the creation of a solar radiation barrier and fire prevention function. The gel phenolic foaming board is intended to provide a sheet material having the function of insulating solar radiation and fire resistance; thereby, the creation not only has excellent heat insulating effect, but also has the effect of fireproof and flameproof first stage.
為了達到上述實施目的,本創作人提出一種具太陽輻射阻隔與防火功能之氣凝膠酚醛發泡板,係包括一本體層,其包括於一酚醛發泡板內佈設有複數個氣凝膠顆粒;以及至少一鋁箔層以包覆於本體層之至少 一表面。 In order to achieve the above-mentioned implementation purposes, the present author proposes an aerogel phenolic foamed board having solar radiation barrier and fireproof function, comprising a body layer comprising a plurality of aerogel particles disposed in a phenolic foamed sheet. And at least one aluminum foil layer to cover at least the body layer a surface.

於本創作之一實施例中,本體層係於上、下兩表面各包覆有一鋁箔層,以提高整體表面的反射率及輻射率特性,達到隔絕太陽輻射之功能。 In one embodiment of the present invention, the body layer is coated with an aluminum foil layer on both the upper and lower surfaces to improve the reflectivity and emissivity characteristics of the entire surface to achieve the function of isolating solar radiation.
藉此,本創作不僅能有效阻絕太陽輻射以提升隔熱效用,並具有防火耐燃一級之效用。 In this way, the creation can not only effectively block the solar radiation to enhance the heat insulation effect, but also has the effect of fireproof and flameproof first class.
