Problems solved by technology

However, these use toxic halogen flame retardants and antimony oxide compounds, which are not preferred in terms of environment and health.
[0006] In short, the current situation is that there is no development of ordinary resins that do not damage the original characteristics of the resin, and do not have environmental and health problems at all, and whose flame retardancy can reach V-0 or V-1 of the UL94 standard. flame retardant

Embodiment

[0096] Hereinafter, synthetic examples, examples and comparative examples are exemplified, and the flame-retardant resin composition compounded with the nanoplatelet layered titanic acid of the present invention and its production method are more specifically described, but the present invention is not limited to These Synthetic Examples and Examples. % and parts shown below are based on weight unless otherwise specified.

[0097]

Synthetic example 1

[0099]27.64 g of potassium carbonate, 4.91 g of lithium carbonate, 69.23 g of titanium dioxide, and 74.56 g of potassium chloride were dry-milled and mixed to obtain a raw material, which was fired at 1100° C. for 4 hours. The fired sample was immersed in 10 kg of pure water, stirred for 20 hours, separated and washed with water, and then dried at 110°C. The obtained white powder is layered titanate K 0.8 Li 0.27 Ti 1.73 o 4 , the average major diameter is 44 μm, and the interplanar spacing (unit thickness) a is 0.778 nm.

Synthetic example 2

[0101] 79.2 liters of 10.9% water slurry of layered titanate obtained in Synthesis Example 1 was prepared, 4.7 kg of 10% sulfuric acid aqueous solution was added, stirred for 2 hours, and the pH of the slurry was adjusted to 7.0. What separated and washed with water was dried at 110° C., and then baked at 600° C. for 12 hours. The obtained white powder is layered titanate K 0.6 Li 0.27 Ti 1.73 o 3.9 , the average major diameter is 44 μm, and the interplanar spacing (unit thickness) a is 0.776 nm.

Abstract

A flame-retardant, characterized in that it comprises a layered titanic acid in the form of a nano sheet which is formed by a method comprising treating a layered titanic acid salt with an acid or warm water and then reacting the resultant mixture with an organic basic compound, or carrying out the step of treating a layered titanic acid salt with an acid or warm water and the step of reacting with an organic basic compound, in one pot, to thereby swell or separate the layers; and a flame-retardant resin composition, characterized in that it comprises 100 parts by weight of a resin and 0.5 to 50 parts by weight of the above layered titanic acid in the form of a nano sheet.

Description

technical field [0001] The invention relates to a flame retardant and a flame retardant resin composition. Background technique [0002] Generally, resins such as polyethylene, polypropylene, polyester, polyurethane, polymethacrylate, and epoxy resin are used because of their electrical insulation, strength, light weight, heat resistance, water resistance, and chemical resistance. It is widely used such as sealing materials for electrical products, building materials, fibers, daily groceries, etc. However, since these common resins are mainly composed of carbon, hydrogen and / or oxygen, they are easily ignited and combusted to generate a large amount of flame, heat, toxic smoke, etc., so their applications are significantly limited. Therefore, various flame retardants have been developed. As organic flame retardants, halogen-based flame retardants and phosphorus-based flame retardants are known; as inorganic flame retardants, antimony oxide compounds, magnesium hydroxide, an...
