Description

Technical Field

[0001] The present invention relates to the technical field of composite materials, and in particular to a flame-retardant ABS composite material and a preparation method and application thereof. Background Art

[0002] ABS resin has a polar oxygen index of only 18 to 20, making it a flammable polymer. Therefore, when used in electrical equipment housings requiring both electrical insulation and flame retardancy, it requires flame retardant modification. Adding flame retardants is the simplest and most effective way to achieve flame retardancy in ABS. Commonly used flame retardants are brominated flame retardants, primarily tetrabromobisphenol A, tris(tribromophenoxy)cyanurate, brominated epoxy oligomers, and decabromodiphenylethane. However, the glow-wire ignition temperature of the flame-retardant ABS composites obtained after modification with these brominated flame retardants remains relatively low, at only 650°C, which is still insufficient to meet the requirements for unmanned electrical equipment.

[0003] To further increase the glow-wire ignition temperature of flame-retardant ABS composites, a commonly used method currently involves introducing phosphorus-containing compounds. For example, CN111763401A discloses a flame-retardant ABS composition comprising the following ingredients by weight: 36.2-82.7 parts ABS resin, 12-20 parts brominated flame retardant, 3-10 parts antimony flame retardant, and 0.2-0.8 parts processing aid. This invention increases the glow-wire ignition temperature of the flame-retardant ABS composition by adding MPP. For example, CN107286563A discloses an intumescent flame retardant for ABS electrical switch covers, comprising the following components and contents by weight: 40-80 parts of piperazine pyrophosphate; 20-60 parts of melamine or a melamine derivative; 0-15 parts of a charring agent, but not 0; 0-15 parts of a synergist, but not 0; 0.2-1 parts of an antioxidant; and 0-1 parts of a smoke suppressant, but not 0. By introducing the intumescent flame retardant, the invention can enable the resulting ABS electrical switch cover to achieve a high glow-wire ignition temperature of 750°C.

[0004] Although the above-mentioned existing technical means can effectively increase the glow-wire ignition temperature of the flame-retardant ABS composite material, it will affect the mechanical properties of the obtained flame-retardant ABS composite material, especially causing the toughness of the obtained flame-retardant ABS composite material to decrease, seriously affecting the widespread application of the flame-retardant ABS composite material.

[0005] Therefore, it is of great significance to develop a flame-retardant ABS composite material with high flame retardancy, high glow-wire ignition temperature and high toughness. Summary of the Invention

[0006] In response to the shortcomings of the prior art, the present invention aims to provide a flame-retardant ABS composite material, a preparation method thereof, and applications thereof. The flame-retardant ABS composite material has a high flame retardancy and a high glow-wire ignition temperature, so that products thereof can meet the requirements of unmanned operation. At the same time, it also has excellent mechanical properties, especially high toughness.

[0007] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a flame retardant ABS composite material, wherein the flame retardant ABS composite material comprises the following components in parts by weight:

[0016] Preferably, the melt index of the ABS resin under the test conditions of 220° C. and 10 kg is 1 to 30 g / 10 min, for example, 1 g / 10 min, 2 g / 10 min, 4 g / 10 min, 6 g / 10 min, 8 g / 10 min, 10 g / 10 min, 12 g / 10 min, 14 g / 10 min, 16 g / 10 min, 18 g / 10 min, 20 g / 10 min, 22 g / 10 min, 24 g / 10 min, 26 g / 10 min, 28 g / 10 min or 30 g / 10 min, etc.

If only tris(tribromophenoxy)cyanurate is used as the brominated flame retardant, it is easy to precipitate when added in a high amount, which will affect the appearance of the flame-retardant ABS composite product.

[0091] Table 3

[0092]

[0093]

[0094] According to the data in Table 3, we can see that:
