Abstract

The invention discloses a glass PVB film with sound insulation and ultraviolet insulation functions and a preparation method thereof, and belongs to the field of PVB films. The glass PVB film with the sound insulation and ultraviolet insulation functions comprises a middle layer and PVB layers arranged on the two sides of the middle layer respectively, wherein the middle layer and the PVB layers are subjected to hot press molding at 130-140 DEG C to form the glass PVB film, and the middle layer is obtained by adding grafted shell powder into a polymer emulsion, then adding a melt blend of modified bentonite and PA6, finally adding EVA resin, and after stirring is finished, co-extruding or roll-forming. According to the glass PVB film, the two PVB layers are subjected to hot press molding on the two sides of the middle layer to obtain the glass PVB film, the middle layer is made of the polymer emulsion, the grafted shell powder and the melt blend of the modified bentonite and the PA6, the lamellar spacing of the modified bentonite is increased so as to prevent external media from entering the glass PVB film, the toughness of the PVB film is stabilized through the PA6 by matching with the PA6, and the grafted shell powder is also matched, so that the sound insulation and ultraviolet insulation performance of the product is enhanced.

Description

technical field [0001] The invention relates to the field of PVB films, and more specifically relates to a glass PVB film with sound-insulating and ultraviolet-proof functions and a preparation method thereof. Background technique [0002] PVB interlayer film is a translucent film. PVB interlayer film is mainly used for laminated glass. It is a special glass made by inserting a layer of PVB film between two pieces of glass, compounding and heating under high pressure. PVB laminated glass is widely used in construction, automobile, photovoltaic and other industries due to its multiple functions such as safety, heat preservation, noise control and ultraviolet isolation. The PVB intermediate film produced with special formula is also widely used in aerospace, military and high-tech industries, such as aircraft, aerospace products, military instruments, solar cells and solar receivers. [0003] The existing glass PVB film has poor sound insulation and UV insulation functions, w...
