Abstract

The invention discloses a flame-retardant and smoke-suppressing PTT polyester composite material and a preparation method thereof, relates to the field of polyester preparation, and comprises the following raw materials in parts by mass: 100 parts of PTT polyester, 5-80 parts of modified polyester, glass fiber 5-50 parts, 10-30 parts of nanocomposite flame retardant containing hydroxide, 5-30 parts of carbon forming agent, 1-30 parts of toughening agent, 1-30 parts of coupling agent, 0.1-1 parts of antioxidant Parts, 0.01-4 parts of nucleating agent. In the present invention, the carbon forming agent and the nanocomposite flame retardant containing hydroxide are used in combination, which not only can prevent flames, but also reduces the generation of toxic smoke, and has the effect of suppressing smoke. While polluting the environment, it takes away a lot of heat.

Description

technical field [0001] The invention relates to the field of polyester preparation, in particular to a flame-retardant and smoke-suppressing PTT polyester composite material and a preparation method thereof. Background technique [0002] PTT (polytrimethylene terephthalate) is a new type of polyester with excellent performance in the polyester family. Its special "odd carbon effect" makes it have a unique helical structure and very good elasticity. At the same time With the softness of nylon, the bulkiness of acrylic fiber and the anti-fouling and antistatic properties of polyester, it is widely used in the fields of textile industry, decoration and engineering plastics. In recent years, with the continuous development of blending technology, PTT polymer alloy products have attracted more and more attention, and are widely used in electronics, electrical industries, auto parts industries, manufacturing industries, etc. Usually, electronic and electrical products are resistan...
