Problems solved by technology

However, in order to impart flame retardancy to a material using the additive-type flame retardant, a large amount of the flame retardant is used, causing some defects such as changes in properties of the base material and deterioration of transparency
Therefore, additive flame retardants are not suitable for products requiring high transparency

Embodiment 1

[0064] A 2 mm thick base film sample was prepared by injection molding using polymethyl methacrylate (PMMA) as the main component. Next, the sample was dipped into a tank filled with a coating solution containing 5 wt% perhydropolysilazane in xylene solvent to form a flame retardant coating on the surface of the base film. . With the surface of the sample fully wetted with the solution, the sample was removed from the solution and placed in a convection oven at 60°C for 10 minutes to evaporate residual solvent from the sample. Next, after placing the sample in a thermo-hygrostat and curing it at a temperature of 60° C. and 90% RH for 24 hours, a flame retardant transparent film including a flame retardant coating was prepared.

Embodiment 2

[0066] A flame retardant transparent film was prepared in the same manner as in Example 1, except that a polymer resin including polyethylene terephthalate (PETG) was used as a main component and a base film sample was prepared by injection molding.

Embodiment 3

[0068] A flame retardant transparent film was prepared in the same manner as in Example 1, except that a polymer resin including polycarbonate (PC) was used as a main component and a base film sample was prepared by injection molding.

Abstract

Disclosed is a method for manufacturing a flame resistant and transparent film having a high transparency after imparting flame resistance through flame resistance treatment. The method for manufacturing the flame resistant and transparent film according to the present invention comprises the steps of: (a) preparing a transparent base film; (b) forming a flame resistant coating layer by coating a flame resistant material comprising a polysilazane onto at least one surface of the base film; (c) drying the flame-resistant coating layer so as to remove residual solvents in the flame-resistant coating layer; and (d) curing the flame-resistant coating layer under a humid environment. The present invention is characterized by the flame-resistant coating layer and a laminated body of the base film having an optical property in which a measured haze value is less than 0.3.

Description

technical field [0001] The present invention relates to a method for manufacturing a flame retardant transparent film, and a flame retardant transparent film manufactured by the method, and more particularly, to a method for manufacturing a flame retardant film exhibiting outstanding flame retardancy and transparency. The method of agent transparent film. Background technique [0002] Flame retardants refer to materials that exhibit the property of delaying combustion when exposed to high temperature or flame. The flame retardants are widely used to delay ignition and prevent the spread of combustion by improving the physical and chemical properties of flammable polymer materials. [0003] With the increase in the application of polymer materials in the fields of building construction, automobiles, electronics, and aerospace industries, for fire safety, there is an increasing need for polymer materials with flame retardancy, and the demand for flame retardants is also grow...
