Description

双面网格芳纶氟橡胶布Double-sided mesh aramid fluororubber cloth 技术领域technical field
本实用新型涉及胶布技术领域，具体为双面网格芳纶氟橡胶布。The utility model relates to the technical field of adhesive cloth, in particular to a double-sided grid aramid fluororubber cloth.
背景技术Background technique
现有的氟橡胶布传统工艺通常先将氟橡胶加温软切块，加入溶剂丙酮稀释氟橡胶块用搅拌机搅拌成胶浆。在涂布机上涂覆，涂覆时涂布机烘箱通道加热，溶剂丙酮挥发，吸收器回收不完全。若防护不佳，人体吸收还会对身上造成伤害。丙酮气体进入大气中也会造成对大气生态环境的污染。安全方面：一旦涂覆氟橡胶的胶浆桶中挥发的丙酮气体浓度超标后，若在生产中产生静电火花，会引起烘箱管道起火、甚至爆炸伤人、形成火灾，并且胶布柔软性不好、会起泡、粘合力弱、拉伸强度小。In the existing traditional process of fluororubber cloth, the fluororubber is usually heated and softly cut into pieces, and then the fluororubber block is diluted with solvent acetone and stirred with a mixer to form a mortar. When coating on a coating machine, the oven channel of the coating machine is heated, the solvent acetone is volatilized, and the absorber recovery is incomplete. If the protection is not good, the human body will absorb it and cause harm to the body. Acetone gas entering the atmosphere will also cause pollution to the atmospheric ecological environment. Safety: Once the concentration of volatilized acetone gas in the fluorine rubber-coated mortar barrel exceeds the standard, if static sparks are generated during production, it will cause the oven pipeline to catch fire, or even explode and hurt people, resulting in fire, and the adhesive tape is not soft enough. Foaming, weak adhesion and low tensile strength.
