Problems solved by technology

People have also tried to add some anti-adhesive agents in the film formula, such as patent documents CN02825306, CN200480011069, CN200680008950, although also slightly effective, these anti-adhesive agents are all dissolved or dispersed evenly in the entire PVB film, resulting in PVB film The anti-adhesive agent on the surface layer is too small to achieve the anti-adhesive effect that can prevent it from being protected by the isolation film. However, when enough anti-adhesive agents are added to the formula, it will affect the haze, light transmittance, and Adverse effects such as adhesion

Abstract

The invention discloses an anti-blocking PVB (Polyvinyl Butyral) rubber sheet with long-term isolating membrane-free protection at an environmental temperature greater than 10 DEG C and a preparationmethod thereof. Some anti-blocking agents capable of modifying PVB hydroxyls into other groups or increasing steric hindrance among the PVB hydroxyls are screened out, and mainly distributed on the PVB surface by virtue of a novel manufacturing method before, during and after molding of the PVB rubber sheet, intermolecular hydrogen bonding on the surface of the PVB rubber sheet is weakened on a micro level, and mutual adhesion of the PVB rubber sheet is inhibited. Therefore, the anti-blocking PVB rubber sheet has anti-blocking property and can avoid isolating membrane protection at the environmental temperature greater than 10 DEG C. The PVB rubber sheet comprises the following overall components in parts by weight: 0.0001-10 parts of an anti-blocking agent, 0.0001-10 parts of other typesof assistants, 0.0001-2 parts of water, 3-50 parts of a plasticizer and 28-96.9997 parts of resin powder.

Description

technical field [0001] The invention relates to an anti-adhesion PVB film without isolation film protection for a long time when the temperature is higher than 10°C and a preparation method thereof, which belongs to the field of polymer materials. Background technique [0002] PVB is the abbreviation of polyvinyl butyral, which is a polymer resin material, and its Chinese name is polyvinyl butyral. [0003] PVB film is usually made of PVB resin powder and plasticizer as the main raw materials, and is thermoplastically extruded by an extruder. [0004] PVB film is a solid adhesive film widely used in automotive laminated glass, architectural laminated glass, photovoltaic double-glass laminated components and other fields. PVB films currently on the market are divided into single-layer PVB films, three-layer PVB films, multi-layer PVB films, PET film composite PVB films, PU film composite PVB films, etc. according to their structures; Thermal PVB film, PVB film for sound ins...
