Abstract
The invention discloses a method for producing laminated glass in a rolling process, which comprises the following steps of: firstly preparing a glass lamination film, then heating the glass lamination film at the temperature higher than the fusion point of a thermoplastic material, tightly pressing upper and lower-layer glass by using the pressure of a roller to extrude air bubbles in middle-layer plastic, and after combining the three layer together, performing cooling formation to form the laminated glass. According to the method, the upper and lower-layer glass and the middle-layer plastic can be synchronously fed so that the laminated glass can be continueously produced, and therefore, the method has the advantages of short time consumption, high production efficiency and safe and reliable operation.
Description
Technical field
The present invention relates to a kind of method that adopts rolling process to produce doubling glass.
Background technology
Produce at present the doubling glass method and be film is placed in the middle of two layers of sheet glass, put into the autoclave pressurization and be adjacent to, by heating film is melted again, removal of bubbles in crack and the glue, after being adjacent to again decompression find time, extract out in vacuum and melt in glue cooling forming behind the microbubble.This production method relates to pressurization, decompression process, and flow process is complicated, time-consuming, can only produce in the gap, and efficient is low, processing safety is poor.
Summary of the invention
The invention provides a kind of method that adopts rolling process to produce doubling glass, it can make levels glass and middle doubling be synchronized to into, can produce continuously like this, not only weak point consuming time, production efficiency are high, and operational safety is reliable.
The present invention has adopted following technical scheme: a kind of method that adopts rolling process to produce doubling glass, it may further comprise the steps: at first prepare the glass sandwich film, then the glass sandwich film is heated and be higher than under the thermoplastic material melting temperature, compress levels glass by roller pressure, extrude the bubble in the plastic cement of middle layer, make three laminatedly to be integrated rear cooling forming and to form doubling glass.
Described glass sandwich film is polyvinyl alcohol, and the Heating temperature of polyvinyl alcohol is 150 ℃-180 ℃.Described glass sandwich film is thermally melting urethane, and the Heating temperature of thermally melting urethane is 190 ℃-220 ℃.Described glass sandwich film is polystyrene, and the Heating temperature of thermally melting urethane is 170 ℃-200 ℃.The described method that the glass sandwich film is heated is warm air beating, electrically heated, radiation heating or steam indirect heating.Pressure was 2.4kg/ square centimeter-5kg/ square centimeter when described pair of rollers glass carried out roll extrusion.
The present invention has following beneficial effect: the present invention is being higher than under these thermoplastic material melting temperatures, compress levels glass by roller pressure, extrude the bubble in the plastic cement of middle layer, make three laminatedly to be integrated rear cooling forming, the method of heating can warm air beating, electrically heated, radiation heating or steam indirect heating, can make like this levels glass and middle doubling be synchronized to into, can produce continuously, weak point consuming time, production efficiency are high, operational safety is reliable.
