NMT-based PBT composition and manufacturing method

Abstract

The invention provides NMT-based PBT plastic composition and manufacturing method, which is prepared from, by weight, 25-80 parts of polybutylene terephthalate, 1-25 parts of polybutylene terephthalate, 5-50 parts of glass fiber, 10-50 parts of thermal conductive additive, 3-20 parts of flexibilizer, 0.1-10 parts of nucleating agent, 0.1-10 parts of flowing modifying agent, 0.1-5 parts of heat stabilizer, 0.1-5 parts of weathering agent, 0.1-5 parts of lubricating agent, and 0.1-3 parts of pigment. It, by different raw materials and ratios, produces thermal plastic PBT compositions of easy molding, high strength, good tenacity, good heat-conducting property, and high adhesive strength with metal, meeting requirements for nanometer molding technology.

Description

technical field [0001] The invention belongs to the technical field of new polymer materials, and in particular relates to a thermoplastic PBT composition which is easy to form, high in strength, good in toughness, good in thermal conductivity and strong in bonding with metals. Background technique [0002] At present, with the rapid development of consumer electronics technologies such as smart phones and tablet computers, more and more new technologies and materials are applied to these fields. On the one hand, consumers have higher and higher requirements for the appearance, touch, size, and weight of these handheld devices, which makes metal materials more and more widely used; on the other hand, as the demand for these handheld devices increases, how to Improving production efficiency, saving costs, and integrating components are also difficult problems faced by various manufacturers. [0003] Generally speaking, the traditional metal middle frame processing usually ad...

Problems solved by technology

[0004] In addition, with the lightweight, thin-walled, miniaturized, integrated, and functionally diversified electronic products, heat dissipation has also become a problem that cannot be ignored. Heat is difficult to quickly transfer to the outside of the device for heat dissipation. On the one hand, the temperature rise of the handheld device will reduce the consumer experience, and on the other hand, it will also have an adverse effect on the internal electronic devices. Therefore, the thermal conductivity of plastics is also particularly important.

[0005] Although there are many patented inventions of NMT technology related to PBT, and there are also many patented inventions of heat conduction related to PBT, but there is no patented invention that combines the two and applies them to electronic equipment.
