單組份聚氨酯密封膠（高彈性！高粘接力） 聚氨酯密封膠的優點和用途。聚氨酯膠屬于工業膠粘劑，主要有粘接、密封和表面處理，聚氨酯的優點是非常多的，所以在建筑、交通、電子等行業都有廣泛的應用，這里我們為大家介紹聚氨酯膠中的一種聚氨酯密封膠，下面所介紹的就是聚氨酯密封膠的一些優點和用途。 The advantages and uses of polyurethane sealants. The polyurethane adhesive belongs to industrial adhesives, mainly bonding, sealing and surface treatment, polyurethane has the advantages of very much, so it is widely used in construction, transportation, electronics and other industries, here we introduce a kind of polyurethane sealant polyurethane rubber, some advantages and uses the surface is polyurethane sealant the.
The advantages of polyurethane sealant: 1、單組份、室溫濕氣固化，低揮發性氣味。 1, one component, moisture curing at room temperature, low volatile. 2、高觸變性，立面和頂部施工不流淌。 2, high touch denaturation, the elevation and the top construction do not flow. 3、具有高的拉伸強度、優良的彈性。 3. It has high tensile strength and excellent elasticity. 4、耐磨性、耐寒性，耐水性。 4, wear resistance, cold resistance, water resistance. 5、抗老化和風化，對基材無腐蝕、無滲透污染。 5, anti aging and weathering, no corrosion to the base material, no seepage pollution. 6、耐候性好，耐油性能優良，耐生物老化，價格適中。 6, good weather resistance, good oil resistance, biological aging, moderate price. 7、表面可噴漆，可打磨。 7, the surface can be painted, can be grind. 8、可粘結多種材料，經批準可接觸食品。 8, can be bonded with a variety of materials, approved to contact food. 9、低溫柔軟性，性能可調節范圍較廣，機械強度大。 9, low soft and soft, the performance can be adjusted wide and the mechanical strength is big. 10、粘接性好、復原性好，可適合于動態接縫。  10, good adhesion, good resilience, and suitable for dynamic joint. 11、使用壽命可達15~20年。 11. The service life can be up to 15~20 years. 12、固化后膠層為彈性體，有良好的抗冷熱變化、抗應力變化等性能。 12, the solidified rubber layer is elastic body, and has good resistance to cold and heat change, resistance to stress change and so on. 13、對各種基材有廣泛的附著力。 13. It has extensive adhesion to various substrates. 聚氨酯密封膠的用途： Use of polyurethane sealant: 聚氨酯密封膠主要用于客車空調、焊縫、行李箱等部位密封，船舶、機車、建筑、涂裝等行業密封及低強度粘接。客車內飾、機車、集裝箱、冷庫、船舶等接縫填縫。船舶內飾、甲板、焊縫及管道、建筑防水、防塵填縫密封。聚氨酯密封膠還可用于電纜(如地下電纜)的柔性接頭、電子元器件的灌封，以防塵抗震;用于隔熱體系如冷藏車、冷庫保溫層及低溫容器的粘接密封等。 Polyurethane sealants are mainly used for sealing of buses, air conditioners, welding seams and trunk, etc. the sealing and low strength bonding of ships, locomotives, buildings, coatings and other industries are also carried out. Seams and seams for passenger car interior, locomotive, container, cold storage, ship and so on. Ship interior, deck, weld and pipe, building waterproof, dustproof sealant seal. Polyurethane sealant can also be used for flexible joints of cables (such as underground cables) and electronic components for dust proof and aseismic. It is used for bonding and sealing of insulation systems, such as refrigerated trucks, cold storage insulation and cryogenic vessels. 聚氨酯密封膠的缺點： Defects of polyurethane sealant: 1、不能長期耐熱。 1. It can't be heat-resistant for a long time. 2、淺色配方容易受紫外光老化。 2, the light color formula is easy to suffer from ultraviolet light aging. 3、單組份膠貯存穩定性受包裝及外界影響較大，通常固化較慢。 3, one component storage stability by large packaging and outside influence, usually curing slower. 4、高溫環境下可能產生氣泡和裂紋。 4. Bubbles and cracks may be produced in high temperature environment. 5、許多場合需要底涂。 5. Many occasions require a bottom coating. 6、同時聚氨酯密封膠耐水性也較差，特別是耐堿水性欠佳。 6. At the same time, the water resistance of the polyurethane sealant is also poor, especially the alkali water resistance is not good. |
