Embodiment 1

[0024] PVB intermediate film with fireproof function, in parts by mass, 0.3 part of antioxidant, 0.1 part of ultraviolet light absorber, 0.03 part of cohesion modifier and 100 parts of PVB resin powder are mixed and stirred, and then, this PVB pre- The mixed material is added to the twin-screw extruder, and at the same time, 40 parts of flame-retardant plasticizer is quantitatively injected into the solid conveying section of the extruder with a metering pump. thick PVB sheet.

Embodiment 2

[0026] Except for increasing the addition amount of the flame retardant plasticizer to 45 parts, the proportioning and processing technology of other components are the same as in Example 1.

Embodiment 3

[0028] Except for increasing the addition amount of the flame retardant plasticizer to 50 parts, the proportioning and processing technology of other components are the same as in Example 1.

Abstract

The invention belongs to the field of plastic molding technology, and more particularly relates to a PVB intermediate film with the fireproof function, which is prepared by substances based on the parts by weight: 50-150 parts of PVB resin with 16-24% of hydroxyl content, 20-75 parts of flame-retardant plasticizer, 0.1-0.5 part of antioxidant, 0.05-0.2 part of ultraviolet absorbent and 0-0.1 part of bonding force adjusting agent. The PVB intermediate film can prevent kettle explosion accident caused by the plasticizer in a high-pressure kettle, the content of which reaches or exceeds explosion limit, thus avoiding loss; the PVB intermediate film has good optical property and mechanical property, realizes UL94 (0.8mm) V-0 level inflaming retarding effect, and is high in safety; and the PVB intermediate film can be widely applied to the field of sandwich glass of a high-rise building, an automobile, aviation, navigation and the like.

Description

Technical field: [0001] The invention belongs to the technical field of plastic modification, in particular to a PVB intermediate film with a fireproof function. Background technique: [0002] PVB laminated glass interlayer film (referred to as PVB interlayer film) is made of polyvinyl butyral (PVB) resin, mixed with plasticizer triethylene glycol diisocaprylate (3G0) or di-n-hexyl adipate (DHA). It is a kind of polymer material formed by extrusion, plasticization and tape casting. It is a kind of soft sheet. The product is widely used in the fields of laminated glass such as high-rise buildings, automobiles, aviation, and navigation. PVB laminated glass has multiple functions such as safety, heat preservation, noise control and UV isolation. [0003] When the PVB interlayer film is used for light-taking ceilings of large buildings and glass curtain walls of high-rise buildings, its main function is not to fall and hurt people when the glass is broken. However, when a fire...
