Abstract

The invention discloses a PVB (polyvinyl butyral) glass sandwich layer membrane sheet production line which comprises a material burdening device, an extruding machine, a screen exchanger, a mold head, a cooling water tank, a first traction unit, a drying machine, a second traction unit, a thickness measuring instrument, a first heating and tempering unit, a first cooling unit, a second heating and tempering unit, a second cooling unit, a slitting unit, a membrane coating unit and an automatic coiling machine, wherein the extruding machine is connected with the output end of the burdening device; the screen exchanger is connected with the output end of the extruding machine; the mold head is connected with the screen exchanger through a metering pump; a materia inlet of the cooling water tank is connected with the output end of the mold head; the first traction unit is connected with the material outlet end of the cooling water tank; the drying machine is connected with the output end of the first traction unit; the second traction unit is arranged on the material outlet end of the drying machine; the thickness measuring instrument is arranged between the drying machine and the second traction unit; the first heating and tempering unit, the first cooling unit, the second heating and tempering unit and the second cooling unit are sequentially arranged at the rear end of the second traction unit; the slitting unit is arranged at the material outlet end of the second cooling unit; and the membrane coating unit and the automatic coiling machine are sequentially arranged below the rear side of the slitting unit. The PVB glass sandwich layer membrane sheet production line provided by the invention is rigorous in production line structure, a molecular structure of the membrane can be improved and stabilized well through tempering twice, and the membrane sheet performance is improved.

Description

technical field [0001] The invention relates to a PVB glass interlayer diaphragm production line and a working method thereof. Background technique [0002] PVB glass interlayer film is a polymer material formed by polyvinyl butyral resin, plasticized and extruded by plasticizer DHA. The diaphragm has good adhesion to inorganic glass, and has the characteristics of transparency, heat resistance, cold resistance, humidity resistance, and high mechanical strength. It is mainly used for laminated glass. PVB laminated glass is widely used in construction, automobile and other industries due to its multiple functions such as safety, heat preservation, noise control and UV isolation. [0003] Due to the many defects in the existing production system, the produced PVB film is highly viscous, easy to bond after winding, and has poor durability. It is prone to aging under certain irradiation and loses its effectiveness in a short period of time. , affecting the use effect of lamina...
