Abstract

The invention belongs to the technical field of glass film production, and particularly relates to a production method of a transparent sound-proof film. The production method comprises the following steps: (1) copolymerizing polystyrene and butyl acrylate so as to synthesize styrene-acrylic resin, wherein the glass transition temperature of the formed styrene-acrylic resin is 15-30 DEG C, and the damping coefficient of the formed styrene-acrylic resin is greater than 0.3; (2) adopting a hot-melting coating machine for coating so as to form a thin film with the thickness of 0.05-1.0mm; and (3) compounding common glass films at the two sides of the styrene-acrylic resin thin film in a thermal compounding manner. The production method of the glass film with excellent sound-proof performance index, provided by the invention, has the advantages that the styrene-acrylic resin thin film with a large damping coefficient is compounded between two layers of common glass films, so that the glass film formed in the end has soundproof property, the selectivity of laminated glass production is improved, and the whole production process is concise, clear and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of glass film production, and in particular relates to a production method of a transparent sound-insulating film. Background technique [0002] In the field of architectural decoration, laminated glass has been more and more widely used due to its excellent characteristics such as beauty and firmness. Laminated glass includes a glass film layer in the center and glass on both sides. The existing laminated glass (glass film) generally focuses on the aesthetic effect of decoration, and invests in research and development of color, pattern, etc., but pays less attention to other performance indicators, such as sound insulation performance. As people pay more attention to the comprehensive performance of laminated glass products, the above-mentioned sound insulation performance indicators have gradually attracted attention. Contents of the invention [0003] The invention provides a production method of a tr...
