Problems solved by technology

[0005] The Chinese patent with publication number CN 101565536A proposes that adding high GWIT synergistic resin PC and inorganic fillers such as magnesium hydroxide, aluminum hydroxide and zinc borate to the traditional formula of flame retardant reinforced PBT can improve GWIT, but its mechanical properties are generally lower, which limits its application space
[0006] The patent with the publication number CN 101484526A and the patent with the application number US 2009 / 0166576 A1 respectively propose that adding nitrogen compounds and liquid crystal polymers to the traditional flame-retardant reinforced PBT can improve GWIT, but due to the added nitrogen compounds and liquid crystals The higher price of polymers increases the cost, so that polyester products do not show much advantage compared with engineering plastics such as PA66, which has a higher GWIT.

Embodiment Construction

[0060] Further explain the present invention below in conjunction with embodiment, embodiment is only used to further illustrate the present invention, can not be interpreted as the limitation of protection scope of the present invention, those skilled in the art make some non-essential improvements according to the content of the present invention to the present invention And adjustments still belong to the protection scope of the present invention.

[0061] The polyester of embodiment and comparative example is prepared as follows:

[0062] (1) Dry the polyester resin at 100~140°C for more than 3 hours, so that the moisture content does not exceed 0.05% of the weight of the polyester;

[0063] (2) Weigh various raw materials according to the ratio in Table 1;

[0064] (3) The polyester resin is mixed with other components in a high-speed mixer or a rotary premixer to obtain a premix;

[0065] (4) Feed the premix into the twin-screw extruder, under the conveying and shearin...

Abstract

The invention discloses a fame-retardant polyester material with a high glow wire ignition temperature and a preparation method thereof. The flame-retardant polyester material with a high glow wire ignition temperature is composed of the following components in parts by weight: 100 parts of polyester resins, 15-50 parts of bromine-series flame retardant, 5-20 parts of synergistic flame retardant, 0-20 parts of toughening agent, 0-80 parts of carbon forming agent, 5-40 parts of hot oxygen barrier agent, 0-120 parts of fibrous reinforcing agent and 0-10 parts of processing aid. The preparation method of the flame-retardant polyester material with a high glow wire ignition temperature comprises: drying the polyester resins, mixing with other components to obtain a premixed material, then feeding the premixed material into a twin-screw extruder, melting and plasticizing, kneading and mixing, extruding, drawing, cooling, pelletizing, drying and finally packaging. The flame-retardant polyester material with a high glow wire ignition temperature has the advantages of low cost, high glow wire ignition temperature, similar mechanical strength to ordinary flame-retardant polyester and wide application range.

Description

technical field [0001] The invention relates to the field of flame-retardant thermoplastic polymers, in particular to a flame-retardant polyester material with high glow wire ignition temperature and a preparation method thereof. Background technique [0002] Thermoplastic polyester, because of its excellent electrical properties, is widely used in electronic appliances, automobiles and other industries. In order to meet the flame retardant performance requirements of the industry, halogen flame retardants and antimony compounds are usually added to polyester to meet UL-94 flame retardancy. [0003] Unlike the UL-94 standard, the IEC 60695-2 standard of the International Electrotechnical Commission (IEC) specifies requirements for the flame retardancy of plastics used in household appliances. According to this standard, household appliances, especially unsupervised household appliances, should have excellent glow-wire characteristics for connecting parts with a rated curren...
