Description
Technical Field
The invention relates to the technical field of plastic processing, in particular to an embossing device applied to an organic polymer intermediate film for laminated glass.
Background
After the laminated glass is used as safety glass and is crushed by impact, sharp fragments generated after the common glass is crushed cannot hurt people due to the bonding effect of the middle film of the common glass. Laminated glass is expected to play a great role in the safe use of glass. One or more layers of organic polymer intermediate films are sandwiched between two or more pieces of glass, and after special high-temperature prepressing exhaust (or vacuumizing exhaust) and high-temperature high-pressure process treatment, the glass and the intermediate films are permanently bonded into an integral composite glass product.
Commonly used organic polymer interlayer films for laminated glass are: PVB, SGP, EVA, PU, and the like.
The problems of interlayer adhesion and insufficient air discharge between the interlayer and glass always exist in the laminated glass manufacturing industry. Blocking means that polymers are mutually bonded together in the process of processing, storing, transporting and using the intermediate film, so that polymer sheets are deformed in subsequent use, the processing efficiency is reduced, and even the intermediate film cannot be used. The air removal means that air present on the surfaces of the glass plate and the intermediate film is removed. The most common methods of roll evacuation and vacuum evacuation, however, both of these methods may result in insufficient evacuation, resulting in bubbling of the glass out of the autoclave or in subsequent use, which is unacceptable for laminated glass. The two problems described above are particularly likely to occur when the surface pattern of the intermediate film is inappropriate.
In order to reduce the risk of adhesion and improve the exhaust effect, fine and uniform patterns must be arranged on the surface of the intermediate film. Patent CN105102223, embossed polymer sheet, describes the appearance, STR, RPC, mottle value of an embossed PVB interlayer and the anti-blocking and air-release effects of the PVB interlayer. The method adopted is in accordance with patent CN 103379999A. Patent CN103379999A, system, method and apparatus for direct embossing of polymer melt sheets, directly embossing high temperature melts see fig. 1, although partly solving the above problems, there are 4 problems: 1. due to the fact that two steel rollers are adopted for pressing, the thickness difference exists in the transverse direction of the sheet material from the die head no matter how the sheet material is adjusted, and the pattern depth is not consistent in the embossing process. 2. In order to prevent the high-temperature intermediate film from sticking to the pattern roller during the embossing process, a lubricant must be applied to the surface of the pattern roller. 3. The lubricant portion is transferred to the intermediate film surface and the lubricant will soon be transferred off, resulting in the need to re-apply the lubricant, resulting in a production that is not continuous. 4. Although continuous production is possible by means of continuous application of the lubricant, the problem of contamination of the intermediate film by the lubricant is unavoidable.
