Embodiment Construction

[0030] Preparation method: mix each component in a twin-screw extruder (twin-screw diameter is 75mm, aspect ratio is 38), mix at a temperature of 200-300°C, discharge as strands and cool to a temperature capable of granulation Granulate. After the pellets are dried (usually at 80°C in a vacuum oven for 2 days), the resulting dried pellets are processed at a temperature of 245°C-300°C into standard samples for UL94V tests, and are also made according to GB1040, GB9341 , the standard spline specified in GB1843.

Abstract

The invention discloses a halogen-free antiflaming polyester molding compound composite and a preparation method thereof. The halogen-free antiflaming polyester molding compound composite is composed of the following components in weight percent: 10-60% of polyester, 10-50% of filling intensifier, 5-35% of complex flame retardant and 0.1-8.0% of other auxiliary agents. The antiflaming reinforced polyester composite prepared by the invention greatly improves the antiflaming performance of the PET molding compound composite, in particular to the antiflaming performance of thin-wall products. The molding compound composite can be processed by traditional methods, such as injection molding and extrusion molding. In addition, the antiflaming reinforced polyester composite of the invention does not contain halogen, thus protecting environment.

Description

technical field [0001] The invention relates to a flame-retardant polyester composition and its preparation technology. Background technique [0002] Polyethylene terephthalate (PET) is a semi-crystalline thermoplastic resin with good solubility resistance, high heat resistance, good ductility, high strength and modulus, and is widely used in electronics, Communications equipment, computers, televisions, kitchen and home appliances, industrial equipment, lighting systems, garden and agricultural equipment, pumps, medical devices, food handling systems, handles, power and hand tools, bobbins and spindles, and automotive interior and exterior parts. [0003] When PET resin is used in electronics, communication equipment and lighting systems, etc., the material needs to have certain flame retardant properties. In order to make PET resin flame retardant, organic and inorganic flame retardants are generally added to improve the flame retardant grade of the material. Commonly us...
