Problems solved by technology

[0004] However, in order to obtain sufficient flame retardancy, these non-halogen-based flame retardants must be added in large amounts relative to the polymers used in existing base materials. If the amount necessary to achieve flame retardancy is added, processing Decreased adaptability, causing problems in the stability of the base material over time, etc.

Embodiment 1

[0100] Embodiment 1, comparative example 1

[0101] 150 parts by weight of aluminum hydroxide (Showa Denko Hijilite H21, average particle diameter 25 μm ), 3 parts by weight of foaming agent as other additives (surfactant, anionic), 1.0 parts by weight of dispersant (polyphosphate, sodium tripolyphosphate), 2 parts by weight of thickener [CMC (carboxymethyl fiber prime)], the base material was prepared by mixing in a stand mixer.

[0102] These base materials were foamed by a continuous mechanical foamer, and the amounts shown below were applied with a doctor blade on the inner surface of the nonwoven fabric shown below. After coating, it was dried at 160° C. for 10 minutes, and the resulting carpet was evaluated for flame retardancy test, heat resistance, processing suitability, and stability over time of the base material as described above. It should be noted that the solid content of the base material was adjusted to 50% by weight and the viscosity was adjusted to 5,000 ...

Embodiment 2

[0115] Embodiment 2, comparative example 2

[0116] In addition to using 100 parts by weight of latex A2 (Tg: 30° C.) in Example 1 as latex, and adding 100 parts by weight of flame retardants B1 to B4 and b1 to b2 shown below as flame retardants, the rest according to and Carpets were obtained in the same manner as in Example 1, and evaluated by flame retardancy tests. Furthermore, the stability and processing suitability of the base material were also evaluated. In addition, the solid content of the base material was adjusted to 50% by weight with the thickener and water, and the viscosity was adjusted to 5,000 mPa·s. (Measurement was performed with rotor No. 3).

[0117] The results are shown in Table 2.

[0118] The base materials of Examples 2-3 and 2-4 were poor in stability, but excellent in flame retardancy and processing suitability, thereby achieving the first object of the present invention.

Embodiment 3

[0128]In addition to using 100 parts by weight of latex A2 in Example 1 as latex, add 100 parts by weight of aluminum hydroxide used in Example 1, or add 100 parts by weight of ammonium polyphosphate B2-1 to B2-5 shown below (Average particle diameter: 25 μm) Except for the flame retardant, a carpet was obtained in the same manner as in Example 1, and the same evaluation as in Example 1 was performed. In addition, a water-soluble component means what disperse|distributes in water at 20 degreeC 2weight%. Both the solid content of the base material was adjusted to 50% by weight and the viscosity was adjusted to 5,000 mPa·s with the thickener and water. (Measurement was performed with rotor No. 3).

[0129] The results are shown in Table 3.

[0130] The ammonium polyphosphate used in Examples 3-1 to 3-3 has a water-soluble content of 0.2% by weight or less, is excellent in flame retardancy, processing suitability, and base material stability, and satisfies the first requirement...

Abstract

The present invention provides a non-halogen flame-retardant base material that has flame retardancy, excellent processability and heat resistance, and excellent stability over time of the base material without using a halogen flame retardant. The non-halogen flame-retardant base material of the present invention contains: the following (A) and (B), relative to 100 parts by weight (converted to solid content) (A) vinyl cyanide-acrylic acid copolymer water-based latex, (B ) is 20-500 parts by weight (B-1) of at least one non-halogen flame retardant selected from ammonium polyphosphates, phosphoric acid esters and water-soluble ammonium phosphates and / or 20-500 parts by weight (B-2 ) non-halogen metal hydrate [However, when using (B-1) and (B-2) together, (B-1)+(B-2) = 20 to 500 parts by weight], by The base material is coated on the inner surface of the carpet and dried to obtain a vehicle or aircraft carpet.

Description

technical field [0001] The present invention relates to a non-halogen flame-retardant base material which does not generate halogen gas when burned, and carpets for vehicles (automobiles, railway vehicles) and airplanes using the base material. Background technique [0002] Currently, halogen-based flame-retardant base materials such as chlorine and bromine are used in fiber interior materials such as carpets of vehicles (automobiles and railway vehicles) and aircraft to comply with flame-retardant regulations. This base material corrodes the incinerator when waste is burned, and when a fire occurs, harmful dioxins are generated, which has the disadvantage of being environmentally unfavorable. [0003] On the other hand, as non-halogen flame retardants, non-halogen flame retardants such as ammonium polyphosphate, water-soluble ammonium phosphate and phosphoric acid ester, and non-halogen flame retardants such as aluminum hydroxide and magnesium hydroxide are known. Metalloi...
