Embodiment Construction

[0009] In order to improve the flame retardancy and heat resistance of plastics, the embodiments of the present invention provide a plastic, a manufacturing method thereof, and a housing. In the technical solution of the present invention, the plastic contains a flame retardant system and an oxidation-resistant additive synergistic with the flame retardant system, which can improve the flame retardant grade of the plastic to 5VB, and the heat resistance of the plastic is also greatly improved, which is expressed as Vicat softening temperature Above 100°C, the casing made of the plastic can meet the requirements of safety regulations for information technology equipment. In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by taking non-limiting examples as examples below.

[0010] Embodiments of the present invention firstly provide a plastic, including:

Abstract

The invention relates to the technical field of a material, and particularly relates to a plastic as well as a production method and a shell thereof, which can be used for improving the flame-retardance performance and heat resistance performance of the plastic. The plastic comprises the following raw materials in parts by weight: 45-55 parts of acrylonitrile-butadiene-styrene copolymer, 28-35 parts of styrene-acrylonitrile copolymer, 15-20 parts of flame-retardant system, 3-5 parts of anti-oxidization auxiliaries, and 1-2 parts of compatibilizer, wherein the flame-retardant system comprises a main flame retardant and a compound flame retardant at the weight ratio of (1.8-3.0):1, and the anti-oxidization auxiliaries comprise tetra(2,4-ditertbutylphenyl)-4,4'-biphenyl bisphosphite and hindered phenol antioxidants at the weight ratio of (0.5-2.5):1.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a plastic, a manufacturing method thereof and a casing. Background technique [0002] With the continuous upgrading of science and technology, the functions of electronic equipment are becoming more and more abundant, so the function of the circuit board of electronic equipment is required to be more integrated, which will inevitably require the circuit board to be more complex and carry more computing tasks, so the circuit The calorific value of the board is increasing, so the heat resistance requirements for the housing materials of electronic equipment are gradually increasing. The International Electrotechnical Commission has issued safety standards for audio and video information communication equipment. For large-scale information technology equipment (such as monitors) or computer), it needs to meet the flame retardant grade of 5VB, and the Vicat softening temperature sh...
