[0031] Composition and preparation of extruded resin sheet

[0032] The mixtures or compositions described herein can each be prepared in extruded resin form by a number of methods including mixing the various materials and passing the components through an extruder (eg, a twin-screw extruder). The extruder may include an injection mechanism, and may include a mechanism for adding a dye during or after the extrusion process in order to color the resulting resin material. The injection mechanism can also be used to add a translucent impact modifier, such as a translucent rubber material, during (or at the beginning of) extrusion. For example, in one embodiment, by infusing a flame retardant material (eg, RDP, BAPP, etc.) into the polymer resin after it has passed through the reactor but before it enters the tablet press, the manufacturer can ensure thorough mixing. In one embodiment, the use of an injection-based extruder allows the production of extruded resin sheets at a low...

Embodiment 1

[0046] A fire resistant polyester composition according to the present invention is prepared by mixing the ingredients in the amounts listed below. Percentages are percent by weight:

[0047] 1) 0% RDP 100% PETG

[0048] 2) 5% RDP 95% PETG

[0049] 3) 10% RDP 90% PETG

[0050] 4) 20% RDP 80% PETG

[0051] 5) 5% BAPP 95% PETG

[0052] 6) 10% BAPP 90% PETG

[0053] 7) 20% BAPP 80% PETG

[0054] The polyester resin compositions were then tested for fire resistance, as indicated herein.

[0055] Table 1 (test result of polyester resin composition)

[0056]

[0057] The above-identified polyester resin compositions 2-7 exhibited excellent properties regarding ignition resistance and tendency to burn compared to the control group (Composition 1). Specifically, adding a certain flame retardant to the polyester resin material makes the polyester resin material have excellent fire resistance. Furthermore, many polyester resin compositions are within at least one generally a...

Embodiment 2

[0060] A number of polyester compositions were further prepared with and without polyvinyl chloride ("PVC") and polyvinylidene fluoride ("PVDF") coatings. Horizontal burn tests on these samples showed that covering could further improve fire resistance. Specifically, covering reduces burn length, improves the time for a given resin composition to self-extinguish, and improves the degree of dripping (and formation of burning droplets). In at least some embodiments, coverings comprising PVDF may provide somewhat better fire resistance than coverings comprising PVC.

Abstract

A synthetic fire-resistant resin comprising one or more polycarbonate resin materials and / or polyester resin materials mixed with a flame retardant such as bis-diphenyl diphosphate, a flame retardant. Alternatively, a mixture of polycarbonate resin material mixed with polyester resin material may be covered with a fire-resistant film. The resin sheet can be made to a thickness such that the resin sheet can be used structurally as a conventional building material. In addition, the resin sheet may be made transparent, translucent or colored as required for architectural purposes. Furthermore, the Vicat temperature of the resin sheet makes the extruded resin sheet easy to process using conventional manufacturing techniques and robust enough to be used in a wide range of indoor and outdoor environments. In one embodiment, a fire resistant resin sheet can be combined with a decorative graphic layer to form a decorative panel that can be used in a Class A architectural environment.

Description

technical field [0001] The present invention relates to methods and compositions of refractory resinous materials that can be used in architectural design applications. Background technique [0002] Architectural design in recent years has focused on synthetic polymer resins, which can be used as windows, partitions, walls, etc. in offices and homes. Specifically, decorative polymeric resin materials (or "resins") are now particularly popular compared to decorative cast or laminated glazing materials because decorative resins can be made more flexible and compatible with cast or laminated glass materials. Glass has the same clear, translucent or tinted appearance, but at a lower cost. Decorative resins further offer greater flexibility in color, texture, gauge and impact resistance compared to glass. In addition, since decorative resins of various artistic colors and images can be formed, it has a fairly wide range of applications. This flexibility applies at the manufact...
