Description
本發明涉及一種止水隔熱複合粉體，特別是一種摻混玻璃粉的環保型止水隔熱複合粉體。 The invention relates to a water-stop heat insulation composite powder, in particular to an environment-friendly water-stopping heat insulation composite powder mixed with glass powder.
為了達到隔熱效果，目前的建築物大都是在建築物的頂樓或樓板舖設隔熱磚、發泡水泥及保麗龍等隔熱材料，但，這些隔熱材料只具備隔熱效果，對於阻止水流滲入建築物的防漏止水效果則不佳。 In order to achieve the heat insulation effect, most of the current buildings are insulated with insulating bricks, foamed cement and styrofoam on the top floor or floor of the building. However, these insulating materials only have insulation effect, The leakage prevention effect of water flowing into the building is not good.
為解決同時兼具止水及隔熱的問題，另一種建築物的防水隔熱結構，如圖1所示，是在建築物的頂樓或樓板10上，依序由下而上舖設上一止水隔熱粉層20、一PE發泡板層30及一混凝土層40，且所述混凝土層40內埋一點焊鋼絲網層50加強其結構強度。 In order to solve the problem of both water stop and heat insulation, the waterproof and heat insulation structure of another building, as shown in Figure 1, is placed on the top floor or floor 10 of the building, sequentially laying down from the bottom to the top. The water heat insulation powder layer 20, a PE foam board layer 30 and a concrete layer 40, and a layer of the welded steel mesh layer 50 embedded in the concrete layer 40 enhances the structural strength thereof.
其中，所述止水隔熱粉層20是選用粉狀天然礦石為材料，兼具防水及隔熱的效果；尤其是，建築物的頂樓或樓板10借助止水隔熱粉層20的舖設，建築物的頂樓或樓板10確實收到兼具防水及隔熱的效果。除此之外，當建築物的頂樓或樓板10遇到出現裂縫時，所述止水隔熱粉層20的粉狀天然礦石，還具備適時自動填補裂縫特性，可適時發揮防漏效果阻止水流從建築物的裂縫滲入。 Wherein, the water-stopping heat-insulating powder layer 20 is made of powdered natural ore as a material, and has the effects of waterproofing and heat insulation; in particular, the top floor or the floor slab 10 of the building is laid by the water-stop heat insulating powder layer 20, The top floor or floor slab 10 of the building does receive both waterproof and thermal insulation. In addition, when the top floor or floor slab 10 of the building encounters cracks, the powdery natural ore of the water-stopping heat-insulating powder layer 20 has the characteristics of automatically filling the crack at the right time, and can timely prevent the water flow by preventing leakage. Infiltrated from cracks in the building.
所述止水隔熱粉層20的天然礦石原料，是取自從礦場或採石場用機械方法直接粉碎的天然方解石、石灰石、白堊或貝殼等，再經過 加工製成品質穩定的粉狀碳酸鈣石粉，具無毒、耐燃、不熱脹冷縮、環保、可回收及無公害特性。 The natural ore raw material of the water-stop heat insulating powder layer 20 is obtained from natural calcite, limestone, chalk or shell directly crushed by a mechanical method from a mine or a quarry. It is processed into powdered calcium carbonate powder with stable quality, which is non-toxic, flame-resistant, non-thermal expansion and contraction, environmentally friendly, recyclable and pollution-free.
然而，大量使用粉狀天然石材的後果，是會造成地球礦石資源快速枯竭。基於珍惜地球資源的責任，實有節約使用地球天然礦石資源的必要。 However, the consequences of the extensive use of powdered natural stone are responsible for the rapid depletion of earth ore resources. Based on the responsibility of cherishing the earth's resources, it is necessary to save the use of the earth's natural ore resources.
而另一種可回收再以原用途持續循環使用的玻璃材料，也具備天然石材的阻水效果，也同樣無法為生物所分解。尤其是，玻璃製品一旦廢棄而未經回收處理，不僅造成掩埋場沉重負荷，又不為生物所分解，如進入焚化爐處理，又可能造成爐體損壞。 Another glass material that can be recycled and reused for the original use also has the water-blocking effect of natural stone, and it cannot be decomposed by organisms. In particular, once the glass product is discarded and not recycled, it not only causes heavy load on the landfill, but also does not decompose by the organism. If it enters the incinerator, it may cause damage to the furnace body.
因此，如圖1所示，建築物的防水隔熱結構中的止水隔熱粉層20，如果是以再生玻璃粉末與天然石礦粉末依比例調合而成，不但符合相關單位提倡節能減碳及綠建築的宗旨，並且也實現節約使用天然礦石資源的目的、和一併解決回收處理廢棄玻璃製品的問題。 Therefore, as shown in Fig. 1, the water-stopping and heat-insulating powder layer 20 in the waterproof and heat-insulating structure of the building is formed by blending the recycled glass powder with the natural stone ore powder, and not only conforms to the relevant units to promote energy saving and carbon reduction.

圖2為本發明的止水隔熱複合粉體具備核殼結構的放大說明圖。 Fig. 2 is an enlarged explanatory view showing a core-shell structure of the water-stop heat-insulating composite powder of the present invention.
如圖2所示，本發明的止水隔熱複合粉體60，是由下列兩種成分依重量比均勻混合而成，具備防水及隔熱特性：1.改質碳酸鈣防水粉61占40%~80%，平均粒徑介於5~10微米(μm)；及2.玻璃粉65占60%~20%，平均粒徑介於10~20微米(μm)。 As shown in FIG. 2, the water-stopping heat-insulating composite powder 60 of the present invention is formed by uniformly mixing the following two components according to the weight ratio, and has waterproof and heat-insulating properties: 1. The modified calcium carbonate waterproof powder 61 accounts for 40%. %~80%, the average particle size is between 5 and 10 microns (μm); and 2. The glass powder is 65% to 20%, and the average particle size is between 10 and 20 microns (μm).
其中，所述改質碳酸鈣防水粉61的用量，如果高達80%以上，則達不到節約使用天然礦石資源的目的；如果低於40%以下，則本發明的止水隔熱複合粉體60達不到止水防漏效果。 Wherein, if the amount of the modified calcium carbonate waterproof powder 61 is as high as 80% or more, the purpose of saving natural ore resources is not achieved; if it is less than 40%, the water-stopping heat-insulating composite powder of the invention 60 can not reach the water and leakage prevention effect.
本發明的止水隔熱複合粉體60，限定所述改質碳酸鈣防水粉61的用量占40%~80%的關鍵性技術，是在於所述改質碳酸鈣防水粉61經過改質成為具備核殼結構的粉體，包括：1.一碳酸鈣石粉62，構成所述改質碳酸鈣防水粉61的核結構；及2.一硬脂酸表層63，構成所述改質碳酸鈣防水粉61的殼結構，且披覆在所述碳酸鈣石粉62的表面；所述硬脂酸表層63的被覆量，占所述改質碳酸鈣防水粉61總重量的0.1~7.0%，優選為占0.5~5.0%，更優選為占1~3%。 The water-stopping heat-insulating composite powder 60 of the present invention defines a key technology for the amount of the modified calcium carbonate waterproof powder 61 to account for 40% to 80%, because the modified calcium carbonate waterproof powder 61 has been modified to become The powder having a core-shell structure comprises: 1. a calcium carbonate powder 62, which constitutes a core structure of the modified calcium carbonate waterproof powder 61; and 2. a stearic acid surface layer 63, which constitutes the modified calcium carbonate waterproof The shell structure of the powder 61 is coated on the surface of the calcium carbonate powder 62; the coating amount of the stearic acid surface layer 63 is 0.1 to 7.0% of the total weight of the modified calcium carbonate waterproof powder 61, preferably It accounts for 0.5 to 5.0%, more preferably 1 to 3%.
其中，所述碳酸鈣石粉62的成分中，依重量比，碳酸鈣含量介於95~98.5%，其餘成分為氧化鐵、二氧化矽及氧化鎂等，介於1.5~5%之間。 Wherein, the composition of the calcium carbonate powder 62 has a calcium carbonate content of 95 to 98.5% by weight ratio, and the remaining components are iron oxide, cerium oxide and magnesium oxide, and are between 1.5 and 5%.
所述硬脂酸表層63是以噴霧造粒技術而披覆在所述碳酸鈣 石粉62的表面；在噴霧造粒的披覆過程中，所述硬脂酸表層63是不與所述碳酸鈣石粉62的表面發生任何化學反應，也就是，所述硬脂酸表層63是以物理性吸附方式而披覆在所述碳酸鈣石粉62的表面。 The stearic acid skin layer 63 is coated with the calcium carbonate by a spray granulation technique. The surface of the stone powder 62; during the coating of the spray granulation, the stearic acid surface layer 63 does not undergo any chemical reaction with the surface of the calcium carbonate powder 62, that is, the stearic acid surface layer 63 is The surface of the calcium carbonate powder 62 is coated by a physical adsorption method.
因為，硬脂酸的化學結構，是一端為親水性的結構，另一端為疏水性的結構；在噴霧造粒的披覆過程中，硬脂酸具親水性的一端，以物理性吸附方式披覆了整顆碳酸鈣石粉62的表面，而硬脂酸具疏水性的另一端，則形成披覆了整顆碳酸鈣石粉62的外披覆表面，使得整顆碳酸鈣石粉62的表面獲得改質，從原本為親水性變成疏水性。也就是，所述改質碳酸鈣防水粉61為疏水性粉體，適合與所述玻璃粉65依比例調合成本發明的止水隔熱複合粉體60。 Because the chemical structure of stearic acid is a structure with one end being hydrophilic and the other end being hydrophobic; in the process of spray granulation, the hydrophilic end of stearic acid is draped by physical adsorption. The surface of the entire calcium carbonate powder 62 is covered, and the other end of the stearic acid having hydrophobicity forms an outer cladding surface coated with the entire calcium carbonate powder 62, so that the surface of the entire calcium carbonate powder 62 is modified. The quality is from hydrophilic to hydrophobic. That is, the modified calcium carbonate waterproof powder 61 is a hydrophobic powder, and is suitable for synthesizing the water-stop heat-insulating composite powder 60 of the present invention in proportion to the glass powder 65.
如圖1及圖2所示，本發明的止水隔熱複合粉體60，是符合節能減碳的綠建築環保材料，其使用用途，適用於構成建築物的防水隔熱結構中的止水隔熱粉層20，從而建築物將獲得防水、防漏、隔熱及降低室內溫度的效果。除此之外，台灣位於地震頻繁地帶，如果因為地震頻繁造成建築物的頂樓或樓板10產生裂縫的時候，舖設在建築物的頂樓或樓板10上面的本發明止水隔熱複合粉體60，由材料本身特性使然，將自動填補發生裂縫處，以阻止水流從裂縫處滲透入及適時發揮防漏效果。 As shown in FIG. 1 and FIG. 2, the water-stop heat-insulating composite powder 60 of the present invention is a green building environmentally-friendly material that is energy-conserving and carbon-reducing, and is suitable for use in water-proof and heat-insulating structures constituting a building. The thermal insulation powder layer 20, so that the building will obtain waterproof, leakproof, heat insulation and reduce the indoor temperature. In addition, Taiwan is located in a frequent earthquake zone. If the roof of the building or the floor slab 10 is cracked due to frequent earthquakes, the water-stopping and heat-insulating composite powder 60 of the present invention is laid on the top floor of the building or on the floor 10, Due to the nature of the material itself, the crack will be automatically filled to prevent the water from penetrating into the crack and to prevent leakage.
