胶粘剂又称粘结剂或粘合剂,是一种能把两个物体牢固地粘结在一起的物质。它与铆、焊、螺栓等连接方式相比,具有重量轻,应力分散均匀、工艺简单、密封、防锈、能粘结不同材料等优点。 胶粘剂可分成天然和合成两大类。合成胶粘剂又分树脂型、橡胶型和橡胶与树脂的混合型这三种。树脂型有环氧树脂,聚氨脂、丙烯酸脂、酚醛、尿醛、聚醋酸乙烯、不饱和聚脂等胶粘剂;橡胶型有氯丁橡胶、丁苯橡胶、丁腈橡胶、聚硫橡胶、硅橡胶等胶粘剂。混合型 Adhesive, also known as a binder or adhesive, is a substance that binds two objects firmly together. Compared with the riveting, welding, bolts and other connections, it has the advantages of light weight, uniform stress dispersion, simple process, sealing, rust prevention, and bonding of different materials. Adhesives can be divided into two categories of natural and synthetic. Synthetic adhesives are divided into resin type, rubber type and rubber and resin mixture of these three. Resin type Epoxy resin, polyurethane, acrylic, phenolic, urea formaldehyde, polyvinyl acetate, unsaturated polyester and other adhesives; rubber neoprene, styrene butadiene rubber, nitrile rubber, polysulfide rubber, silicon Rubber and other adhesives.
