Definitions
- the present invention relates to a silicone rubber composition that can be colored in various colors and has excellent flame retardancy and fire resistance.
- Silicone rubber has a strong basic structure of polymer chains even at high temperatures of 300°C or higher, so unlike carbon-based polymers, it does not thermally decompose, so it is flexible and has excellent thermal stability and flame retardancy, so it is used in transportation, aviation, space, architecture, civil engineering, electricity, textiles, and cosmetics. It is widely used in many application industries such as In addition, since this characteristic of silicone rubber remains as silica not containing crystalline SiO 2 even under conditions of 1000° C. or higher, such as fire, silicone rubber is used as a basic binder for fireproof materials. However, since silicone rubber is brittle after digestion despite its excellent thermal stability, it is common to use an inorganic filler capable of improving fire resistance.
- conventional fireproof compositions containing silicone rubber generally include silicon rubber, graphite and vermiculite as fireproofing agents, iron oxide as fireproofing aids, and inorganic fibers as fireproofing agents.
- Korean Patent Registration No. 1896898 discloses a silicone rubber composition containing silicone rubber, a curing agent, a fire retardant made of natural minerals and non-combustible materials, a flame retardant and a fire retardant auxiliary.
- the conventional refractory composition such as Patent Document 1 has a problem in that it contains graphite as a refractory agent and thus lacks color toning or mechanical properties of a cured product produced due to a large amount of filler.

- the elongation of the refractory silicone rubber was measured according to the method described in ASTM D412. Specifically, after manufacturing a 2mm-thick ASTM D412 Type C specimen, the Universal Testing Machine was used as a measuring instrument to measure the length increase of the final elongated specimen when the specimen was broken. measured. Afterwards, the increase in length was determined as an elongation by calculating a percentage for the initial horizontal length of 2 cm of the specimen.
- a sheet-like specimen with a thickness of 2 mm is mounted on a stand that can be fixed, and then, using a butane gas torch (gas consumption 80 g / h, 960 kcal), one side is burned with a flame length of 10 cm for 10 minutes. After adding, the silicone rubber was removed from the cradle, and the appearance was checked, and it was judged as poor when a hole was drilled or burnt out, normal when cracks occurred, and good when the appearance was good.
- gas consumption 80 g / h, 960 kcal gas consumption 80 g / h, 960 kcal
- Comparative Example 1 without quartz had poor tensile strength, elongation and flame retardancy, and Comparative Example 2 without wollastonite had poor flame retardancy and fire resistance.
- Comparative Examples 3 and 4 containing no cerium oxide and titanium dioxide had poor fire resistance
