Problems solved by technology

[0005] However, the fluidity of this semi-aromatic nylon itself cannot meet the needs of thin-walled, especially thin-walled and long-process products in SMT technology. Especially, engineering plastics for electronic and electrical components need to be reinforced or flame-retardant modified. Adding flame retardants , glass fiber or carbon fiber, etc.,...

Embodiment 1～10

[0086] In the examples, the rheological properties, mechanical properties, and heat resistance properties of the fast-flowing high-temperature-resistant nylon composite material provided by the present invention are tested according to the following methods.

[0087] Rheological properties

[0088] On the RL-11B type melting rate flow meter that Shanghai Scientist Instrument Co., Ltd. produces, measure composite material at 325 ℃, under the pressure of 2.16kg, flow through a certain diameter (used diameter among the present invention is 2.09mm) in 10 minutes ) of the capillary weight. This weight in grams is referred to as the melt flow rate (MFR).

[0089] mechanical properties

[0090] Tensile test is carried out according to the standard ISO 527-1, 2-1993, and the bending test is tested according to ISO 178-2003 on the electronic universal testing machine produced by Shenzhen Xinsansi.

[0091] Heat resistance

[0092] The heat distortion temperature is tested on the XW...

Abstract

The present invention provides composite material used for preparing fast flowing high-temperature resistant nylon, which comprises the following components: 20 to 84.9 weight portions of high-temperature resistant nylon resin and 0.1 to 10 weight portions of flowing modifier, wherein, the high-temperature resistant nylon resin is selected from the semi-aromatic nylon with the self melting point between 290 DEG C to 330 DEG C; the semi-aromatic nylon is obtained by the copolymerization of terephthalic acid or isophthalic acid, the diamine with 4 to 12 carbon atoms and the aliphatic nylon with 6 to 24 carbon atoms. The fast flowing high-temperature resistant nylon of the present invention has good heat resistance and fluidity and good chemical performance, exact formability and size stability and is mainly used for the production of thin-wall product in the electronic appliance field.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a fast-flowing high-temperature-resistant nylon and a preparation method thereof. Background technique [0002] With the development of electronic and electrical components to small, thin-walled, precise, heat-resistant and other high-performance aspects, high-temperature-resistant materials such as nylon 46, nylon 9T, polyphenylene sulfide (PPS), and liquid crystal polymers continue to appear in the field of engineering plastics. They have been widely used rapidly with the development of surface mount technology (SMT). SMT technology has high requirements on the heat resistance, precision molding and dimensional stability of the resin, and the above materials have many shortcomings in performance, formability and price when used in the SMT process, such as PPS molding It is easy to corrode the mold; the joint strength of LCP parts is insufficient;...
