Problems solved by technology

[0011] This example can indeed exhibit a certain degree of flame retardancy and dripping suppression effect, but due to the low heat resistance, there is a problem of low flame retardancy, and the current situation is that dripping suppression has not been established yet, and flame retardancy can be fully exerted Technology

preparation example Construction

[0165] As a manufacturing method of a fibrous structure, the method of manufacturing using a melt spinning machine is mentioned, for example.

[0166] For example, the resin composition obtained by the above method can be cut into small pieces of 3 mm square, and then the small pieces are put into the hopper of a melt spinning machine, and melt spinning is carried out at a temperature above the melting temperature of the matrix resin, thereby A fibrous structure is obtained.

[0167] In addition, a method of imparting a compound containing a flame-retardant element to a fibrous structure in post-processing will be described.

[0168] For example, the compound containing the flame retardant element can be imparted to the fiber structure by processing in a bath, rolling-drying-baking method, rolling-steaming-baking method and the like.

[0169] Specifically, a case where fibers containing polyethylene terephthalate and a polysiloxane compound are prepared by melt spinning, and a ...

[0196] As the matrix resin, polyethylene terephthalate having an intrinsic viscosity (IV) of 0.65 was used. Use polysiloxane compounds 1-12 shown in Table 1, as shown in Table 2, make the compounding ratio of polyethylene terephthalate and polysiloxane compound be 95wt%: 5wt%, obtain A resin composition containing polyethylene terephthalate and a polysiloxane compound. Kneading was performed using a twin-screw extruder under the conditions of a kneading temperature of 275° C., an L / D of 30, and a screw rotation speed of 300 rpm.

[0197] Then, according to the above-mentioned conditions in the dripping property evaluation method of the resin composition and the oxygen index evaluation method, the obtained resin composition was molded, and the dripping property evaluation and the measurement of the oxygen index (LOI value) as an index of flame retardancy were carried out. .

[0198] In addition, since Comparative Example 1 does not contain a polysiloxane-based compound, it wa...

Embodiment 9～16、 comparative example 6～10

[0203] The resin compositions of polyethylene terephthalate and polysiloxane compounds obtained in Examples 1 to 8 and Comparative Examples 1 to 5 were cut into small pieces of 3 mm square. The obtained pellets were dried in a vacuum dryer at 150°C, 12 hours, and 2 Torr, and then dried at a spinning temperature of 290°C, a spinning speed of 1500m / min, a die diameter of 0.23mm-24H (hole), and a discharge volume of 40g. Spinning was carried out under the condition of 1 / min to obtain an undrawn yarn in which the composition ratio of polyethylene terephthalate and polysiloxane compound was 95% by weight: 5% by weight. Next, the undrawn yarn is drawn using a drawing machine. Under the conditions of a processing speed of 400m / min, a stretching temperature of 90°C, and a setting temperature of 130°C, stretching is carried out at a draw ratio such that the fineness of the obtained drawn yarn becomes 85dtex-24 single filaments, thereby obtaining a drawn Silk.

[0204] Then, the drawn...

Abstract

To provide a resin composition and fiber structure that are free from material drip at combustion and excel in flame retardant performance in usages as a flame retardant material, in particular, fiber products, film products, resin molding products, etc. [MEANS FOR SOLVING PROBLEMS] There is provided a polyester resin composition containing a polyester resin and a silicone compound wherein the silicone compound comprises a silicone compound containing at least a structural unit of the formula RSiO1.5 (R: organic group), and wherein the weight ratio of silanol groups of the silicone compound is in the range of 2 to 10% based on the total weight of the silicone compound, and wherein the blending ratio of silicone compound to polyester resin in terms of weight ratio is =100:0.1 but <100:10.

Description

technical field [0001] The present invention relates to a flame retardant material, in particular to a flame retardant material capable of exhibiting flame retardancy without dripping (melt dripping) when a thermoplastic material is burned. Background technique [0002] At present, many materials containing halogen-based flame retardants such as chlorine-containing flame retardants and bromine-containing flame retardants have been proposed as flame-retardant methods for materials such as flammable resins and flammable fibers. Flame retardant and antimony flame retardant materials. However, although these materials are excellent in flame retardancy, there is a problem that halogen-based flame retardants may generate halogenated gas when burned, and many studies have been made to solve the above-mentioned problems. [0003] For example, many materials containing phosphorus-based flame retardants using phosphorus compounds free of halogen and antimony elements have been propos...
