Problems solved by technology

[0004] However, judging from the literature reports, there are two major problems in the prior art: first, a method for increasing the GWIT temperature is only effective for a small number of specific polymer substrates or formulation systems, and technical personnel in the industry need to use new polymer substrates or When formulating the system, it is necessary to spend a lot of time and energy to develop new methods of improvement; secondly, most of these synergistic additives used to increase the GWIT temperature are used in large amounts, and high additions will affect the mechanical properties and processing properties of the original formula materials. Increases the cost and limits the design space of materials and products for technical personnel in the industry

Abstract

The invention belongs to the field of macromolecule additives, and in particular relates to a composition for improving the ignition temperature of a plastic glowing filament as well as a preparation method and application thereof. The composition comprises a compound of four elements, namely, magnesium, aluminum, silicon and phosphorus, and oxygen, and is prepared by randomly and irregularly mixing an aluminum-phosphorus-oxygen compound A, a magnesium-oxygen compound B and a silicon-oxygen compound C, or respectively wrapping the aluminum-phosphorus-oxygen compound A and the magnesium-oxygen compound B by use of the silicon-oxygen compound C, and further randomly mixing the obtained wrappage. When plastic with the composition is contacted with the glowing filament, a plurality of dense partitioning layers can be rapidly formed at a contact interface, and heat and substance exchange between two sides of the contact interface is effectively prevented, so that the ignition temperature and combustible index of the glowing filament made of a material can be respectively improved to be 800 DEG C and greater than 900 DEG C. The composition provided by the invention is suitable for being used as an assistant additive of modified plastic of various flame retarding systems, and the modified plastic prepared from the composition is applicable to the field of electric component manufacturing.

Description

technical field [0001] The invention belongs to the field of polymer additives, and in particular relates to a composition for increasing the ignition temperature of plastic glow wires, a preparation method and application thereof. Background technique [0002] Since the beginning of the 21st century, electronic and electrical equipment has accelerated towards automation, intelligence and integration, bringing great convenience to people's production, office and life. However, more than 40% of the weight of electronic and electrical equipment is composed of flammable polymer insulating materials (most of which are plastics), which poses a huge fire hazard to people's lives and forces the safety regulations of countries around the world to impose strict regulations on electronic and electrical equipment. The flame retardant requirements of plastics used in electrical appliances are becoming more and more stringent. For many years, the electronic and electrical equipment indu...
