Problems solved by technology

However, although PPE has excellent insulating properties and flame retardant properties, it is difficult for the HWI level of PPE to reach the 0 level specified by UL.
Currently, the flame retardant of PPE materials with 0-level HWI on the market is mainly reinforced and filled materials; because of the introduction of PS to regulate the fluidity of flame-retardant PPE materials, the thermal stability is reduced, the HWI performance is greatly reduced, and rarely can reach 0 level HWI, related patents have no related reports

Embodiment 5

[0053] Comparing Example 1 with Example 5, it can be seen that Example 5 is the same as Example 1 except that the selection of the toughening agent is different, and the toughening agent in Example 1 is styrene-ethylene / butylene-styrene Block copolymer, its flame retardant property, HWI are all better than embodiment 5;

[0054] Comparing Example 1 with Examples 6 to 8, it can be seen that only one of zinc oxide and manganese oxide is contained in Examples 6 to 7, and zinc oxide and manganese oxide are contained in Example 1; the flame retardant in Example 1 The performance and HWI are better than those of Examples 6-7; the metal oxide in Example 8 is magnesium oxide, and the HWIs of Examples 1 and 6-7 are better than those of Example 8.

[0055] Comparing Example 9 with Comparative Examples 1, 2, and 3, it can be seen that Comparative Example 1 does not contain metal oxide and polyoxymethylene, only Metal oxide is contained in Comparative Example 2, and only Polyoxymethylene ...

Abstract

The invention discloses a high-thermal-filament ignition polyphenyl ether composition. The polyphenyl ether composition comprises the following components in parts by weight: 40-90 parts of polyphenylether, 2-40 parts of styrene resin, 1-10 parts of a toughening agent, 5-18 parts of a flame retardant, 0.1-3 parts of polyformaldehyde resin and 0.1-1 part of metal oxide. According to the heat-resistant wire ignition polyphenyl ether material, the quality of a carbon layer is greatly enhanced through the catalytic charring effect of metal oxide and POM in the early stage of ignition, the HWI performance of the material is obviously improved, a good effect on flame retardance is achieved, and the flame-retardant PPE material with the 0-grade HWI can be prepared through the method.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a high-heat wire ignition polyphenylene ether composition and a preparation method and application thereof. Background technique [0002] The hot wire ignition evaluates the difficulty of the material being ignited by the heating wire in the case of electrical short circuit, etc. If the material is easily ignited by the hot wire, it will be ignited quickly and cause a fire when the electrical short circuit occurs. Based on safety considerations, Underwriters Laboratories (UL) even mandates that plastic materials used to insulate live parts (or live parts with insulation thickness less than 0.71mm) must submit hot wire ignition (HWI) test results. [0003] Polyphenylene ether material (referred to as PPE) has been widely used in the field of electrical appliances due to its excellent insulation performance, flame retardancy and heat resistance. However, although PPE ...
