建筑、建材 黑(白)色阻燃玛蹄脂

        本建筑、建材类产品：建筑、建材 黑(白)色阻燃玛蹄脂，由浙江嘉兴市供应商浙江振阳绝热科技有限公司供应，详细信息如下：
玛蹄脂是采用沥青或改性环氧为基料，添以矿物填料，并加入适量的阻燃剂制成的防潮隔汽材料，即防水阻燃玛蹄脂。分为黑色玛蹄脂和白色玛蹄脂，具有气密性、防水性、防冻性、防腐性、不易老化开裂、常温下可以冷施工、干燥后具有阻燃性等特点。它是石油化工等行业中与泡沫玻璃、聚异氰脲酸酯及聚氨酯等绝热材料配套保冷、防火、防潮的理想保冷涂料。除此之外，玛蹄脂还被广泛应用于建筑领域的屋面防水、沟渠填缝等防水工程。
　　　 Flame-retardant mastic, also calLED vapor barrier mastic, is a kind of vapor barrier material, made of asphalt or epoxy resin, added with mineral and adequate flame retardant. It is divided into two kinds of white mastic and black mastic with following features: air-tightness, water impermeability, cold resistance, corrosion protection, and not easy to deteriorate or crack. It has flame retardant after dried and could be used under normal temperature. It is a kind of ideal coating material for cold conservation, fire proofing and moisture resistance together with insulation material, such as cellular glass, PIR-polyisocyanurate and PUR-polyurethane in petrochemical industry. In addition, mastic is widely used as waterproofing material in construction sector.
