Embodiment 1( Embodiment 1-1～1-4 and comparative example 1-1～1-3

[0055] Put 50 parts by weight of piperazine pyrophosphate (the molar ratio of piperazine and pyrophosphoric acid is 1:1) and 50 parts by weight of melamine pyrophosphate (the molar ratio of melamine and pyrophosphoric acid is 2:1) into the jet mill (manufactured by Seishin Co., Ltd.: Co-JET System α-mkIII), and pulverized at room temperature at a nozzle pressure of 0.8 mPA and a supply rate of 500 g / hour to obtain a flame retardant powder. The obtained powder and 1 part by weight of the surface treatment agent (see Table 1) were stirred at 120° C. at 2800 rpm for 10 minutes using a Henschel mixer (manufactured by Mitsui Seizan Co., Ltd.: FM20C / I) to obtain a silicone oil-coated flame retardant .

[0056] The obtained powder was subjected to ultrasonic treatment with a methanol solvent, and the average particle diameter was measured using a particle diameter measuring device (manufactured by Shimadzu Corporation: SALD-2100), which was used as the primary particle diameter. In ...

Embodiment 2

[0073] Example 2 (Silicone oil combined effect) (Examples 2-1 to 2-7)

[0074] 50 parts by weight of piperazine pyrophosphate and 50 parts by weight of melamine pyrophosphate used in Example 1 were charged into a jet mill (manufactured by Seishin Enterprise Co., Ltd.: Co-JET System α-mkIII), and the nozzle pressure was 0.8 at room temperature. The pulverization was carried out at mPa and a supply rate of 500 g / hour to obtain a flame retardant powder. The obtained powder and 1 part by weight of the surface treatment agent (see Table 2) were stirred in a nitrogen atmosphere at 2800 rpm at 150° C. for 10 minutes using a Henschel mixer (manufactured by Mitsui Seizan Co., Ltd.: FM20C / I) to obtain a silicone oil Coated flame retardant.

[0075] The obtained silicone oil coated flame retardant is dispersed in methanol (concentration is 0.3g / 100ml methanol), after ultrasonic treatment (bench type manufactured by Branson Company, treated at room temperature for 10 minutes), particle s...

Embodiment 3

[0082] Embodiment 3 (modified silicone oil) (embodiment 3-1~3-5)

[0083] 50 parts by weight of piperazine pyrophosphate and 50 parts by weight of melamine pyrophosphate used in Example 1 were charged into a jet mill (manufactured by Seishin Enterprise Co., Ltd.: Co-JET System α-mkIII), and the nozzle pressure was 0.8 at room temperature. The pulverization was carried out at mPa and a supply rate of 500 g / hour to obtain a flame retardant powder. The obtained powder and 1 part by weight of the surface treatment agent (refer to Table 3) were stirred in a nitrogen atmosphere at 150° C. at 2800 rpm for 10 minutes using a Henschel mixer (manufactured by Mitsui Seizan Co., Ltd.: FM20C / I) to obtain a silicone oil Coated flame retardant.

[0084] The obtained powder was evaluated in the same manner as in Example 2.

[0085] The results are shown in Table 3.

Abstract

The invention provides a flame retardant composition comprising 1-99 weight parts of a salt of piperazine and an inorganic compound selected from among piperazine phosphate, piperazine pyrophosphate and piperazine polyphosphate, or a mixture of two or more of these piperazine salts (ingredient (A)), 99-1 weight parts of a salt of melamine and an inorganic compound selected from among melamine phosphate, melamine pyrophosphate and melamine polyphosphate, or a mixture of two or more of these melamine salts (ingredient (B)) (wherein, the sum of ingredient (A) and ingredient (B) is 100 weight parts), 0-50 weight parts of an arbitrary ingredient (ingredient (C)), and 0.01-20 weight parts of a silicone oil having a viscosity at 25 DEG C of 5000mm 2 / s (ingredient (D)) which is added thereto. This flame retardant not only has superior flame retarding properties, but also has enhanced powder properties and anti-hygroscopic properties, and when it is added to a resin, there is little change of electrical resistance.

Description

technical field [0001] The present invention relates to a silicone oil-treated flame retardant composition consisting of a (poly / pyro)phosphate compound of piperazine and melamine, and more specifically, to a silicone oil treatment with less secondary agglomeration, An inorganic phosphorus-based flame retardant with excellent powder properties, water resistance, and excellent dispersibility to resins. Background technique [0002] Conventionally, synthetic resins have been widely used in construction materials, automobile parts, packaging materials, agricultural materials, body materials of home appliances, and toys due to their excellent chemical and mechanical properties. However, most synthetic resins are combustible, and must be made flame-retardant depending on the application. Therefore, as a flame retardant method, generally known are halogen flame retardants alone or in combination, inorganic phosphorus flame retardants composed of polyphosphoric acid flame retardan...
