[0024]

[0025] Above-mentioned embodiment and comparative example all adopt following method preparation:

[0026] A kind of preparation method of the high weather resistance halogen-free flame-retardant PC / ABS alloy material of the present invention, comprises the following steps:

[0027] After mixing the raw materials evenly, put them into the twin-screw extruder to extrude and granulate. The temperature of the twin-screw extruder from the feeding section to the head is respectively: 160°C±10°C, 200°C±10°C, 260°C± 10℃, 260℃±10℃, 255℃±10℃, 250℃±10℃, 250℃±10℃, 250℃±10℃, 250℃±10℃, die head: 260℃±10℃;

[0028] Then, through water cooling, dicing and drying, a high weather-resistant halogen-free flame-retardant PC / ABS alloy material specially used for outdoor telecommunication boxes is obtained.

[0029] The special materials for outdoor telecommunication boxes must have good...

Abstract

The invention discloses a high weather resistant, halogen-free and flame retardant PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) alloy material special for an outdoor telecommunication box and a preparation method thereof. The PC / ABS alloy material is prepared from the following raw materials by weight percentage: 60%-80% of polycarbonate resin; 0.1%-10% of acrylonitrile-butadiene-styrene resin; 0.1%-5% of a compatibilizer; 2%-10% of triphenyl phosphate; 2%-10% of resorcinol (diphenyl phosphate); 0.1%-1% of an anti-dripping agent; 0.1%-2% of a light stabilizer; and 0.1%-2% of assistants. According to the invention, the PC and ABS resin with good weather resistance are adopted as the matrix, and through synergy of the compatilizer, the halogen-free flame retardants and the light stabilizer, the halogen-free and flame retardant PC / ABS alloy material with high heat resistance and high performance can be obtained, and can be widely used in the communications industry, the automobile industry, building materials, decoration materials, cables and the electrical industry. The preparation method of the alloy material adopts existing equipment, is simple to operate, and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of chemistry, and in particular relates to an alloy material, in particular to a highly weather-resistant, halogen-free and flame-retardant PC / ABS alloy material for outdoor telecommunication boxes and a preparation method thereof. Background technique [0002] Blending polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS) in a certain proportion to make PC / ABS alloy is the earliest industrial production, currently the most mature, the most widely used and the largest output A PC modified product, this type of alloy can combine the excellent properties of the two: on the one hand, it can improve the heat resistance, impact resistance and tensile properties of ABS, and replace ABS in high-performance fields; on the other hand, it can reduce the PC It is a polymer alloy with comprehensive performance by reducing the cost and melt viscosity, improving its processing performance, and reducing the sensitiv...
