PVB (polyvinyl butyral) glass sandwich layer membrane sheet production line and operating method thereof

Abstract

A PVB glass interlayer film production line, comprising: a batching device, an extruder connected to the output end of the batching device, a screen changer connected to the output end of the extruder, a die head connected to the screen changer through a metering pump, The cooling water tank connected to the output end of the die head at the feed port, the first traction unit connected to the discharge end of the cooling water tank, and the dryer connected to the output end of the first traction unit, located at the discharge end of the dryer The second traction unit at the end, the thickness gauge between the dryer and the second traction unit, the first heating and tempering unit, the first cooling unit, and the second heating and tempering unit at the rear end of the second traction unit in turn And the second cooling unit, the slitting unit arranged at the discharge end of the second cooling unit, the laminating unit and the automatic winding machine arranged at the rear side of the slitting unit in turn. The PVB glass interlayer diaphragm production line of the present invention has a rigorous structure, and the molecular structure of the film can be better improved and stabilized by twice tempering, so as to improve the performance of the diaphragm.

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...
