Abstract
The invention relates to a high-strength laminated glass manufacturing method. The high-strength laminated glass manufacturing method comprises the following steps that firstly, sheet combination is performed; EVA rubber sheets are flatly laid between two layers of tempered glass or more layers of tempered glass to carry out sheet combination; secondly, forming is performed in a composite mode; the glass undergoes sheet combination is preheated at a low temperature, and then heated at a high temperature; thirdly, cooling is performed; the glass heated at the high temperature is cooled and extracted; laminated glass is obtained. The high-strength laminated glass manufacturing method is simple in manufacturing technology and high in production efficiency. The obtained laminated glass has good weather resistance, is applicable to moisture and water-contact environments, high in anti-impact capability and transparency and can be widely applied to bath rooms, safety furniture, indoor partition plates, sightseeing elevator channels, glass guard bars and the like. A manufacturing device is simple, bubbles are not prone to occurring and glue disengagement and other phenomena are avoided.
Description
Technical field

Close in the sheet process and require that toughened glass keeps flat, the tiling of EVA film;
The thickness of described toughened glass is 5-12mm; Preferred 6-8mm;
Described EVA film is the commercially available film that can realize the object of the invention understood by one of ordinary skill in the art.
The thickness of described film is 0.38-0.76mm, preferably 0.38mm;
In order to obtain high strength, strong shock resistance, can control again the proportion of laminated glass simultaneously in certain tolerance range, described toughened glass layer is no more than 4 layers;
2) composite molding
By the first low-temperature prewarming of glass closed after sheet, then heat;
3) cooling
By the glass cools after heat, take out, obtain laminated glass.
In above-mentioned preparation method, in step 1), the described sheet condition of closing is: vacuum tightness 0.08-0.095MPa, 25 ℃ of temperature, humidity<30%;
In step 2) in, described low-temperature prewarming step is at 40-60 ℃ of lower preheating 10-40min; Described heat step for heating 80-120min under 100-110 ℃;
In step 3), described cooling temperature is 40-60 ℃, preferably 50 ℃;
The preparation technology of high-strength laminated glass of the present invention is simple, production efficiency is high, the laminated glass obtained, there is good weathering resistance, be applicable to environment moist and that contact with water, the phenomenons such as strong shock resistance, transparency is high, production unit is simple, be difficult for producing bubble, come unstuck, can be widely used in shower room, safe furniture, indoor partition, sightseeing elevator passage, glass guardrail etc.
