Embodiment 1

[0033] Plasticize and melt 60kg of ABS resin at a temperature of 190-210°C to obtain an ABS resin melt; 10kg of continuous PA66 fibers are impregnated with the melt of ABS resin to completely infiltrate the PA66 fibers. Among them, the continuous PA66 fiber is drawn out from the creel, the tension is adjusted by the tension roller, and then enters the melt impregnation die, where the dispersion and infiltration of the fibers are realized in the die, the fiber content is controlled through the fiber outlet of the die, cooled and solidified, and passed through the die. The pelletizer cuts to a fixed length (eg 8mm, 12mm, etc.). The obtained pellets are batch-mixed with the halogen-free flame-retardant masterbatch at a ratio of 2:1 to obtain the product.

Embodiment 2

[0035] Plasticize and melt 40kg of PP resin at a temperature of 170-190°C to obtain a PP resin melt; 20kg of continuous PET fibers and 20kg of continuous glass fibers are simultaneously impregnated by the melt of PP resin, so that the PET fibers and glass fibers are completely infiltrated . Among them, the continuous PET fiber and glass fiber are drawn out from the creel, the tension is adjusted by the tension roller, and then enter the melt impregnation die, and the dispersion and infiltration of the fibers are realized in the die, and the fiber content is controlled through the fiber outlet of the die, and the cooling Solidified, cut into fixed length (such as 8mm, 12mm, etc.) by pelletizer. The obtained pellets are batch-mixed with the halogen-free flame-retardant masterbatch at a ratio of 5:2 to obtain the product.

Embodiment 3

[0041] A method for manufacturing a thermoplastic resin composite material for a notebook computer casing, comprising the following steps:

[0042] (1) Prepare materials according to the following components and contents: 50kg of thermoplastic resin, 10kg of organic fiber, 10kg of inorganic fiber, 5kg of other additives, 25kg of halogen-free flame retardant masterbatch, among which, the thermoplastic resin is ABS resin, and the organic fiber is nylon 9T fiber , its melting point is higher than that of ABS resin, the inorganic fiber is carbon fiber, and other additives are color masterbatch;

[0043] (2) Control the temperature to 210°C, melt the ABS resin to obtain a melt, and then lead out the nylon 9T fiber and carbon fiber from the creel, adjust the tension through the tension roller, enter the melt impregnation die, fully impregnate the ABS resin melt, and Add the color masterbatch to it, then cool and cut into pellets of fiber-reinforced thermoplastic resin, and finally m...

Abstract

The invention relates to a thermoplastic resin composite material for laptop shells and a manufacturing method thereof. The composite material comprises the following components in percentage by weight: 40 to 60 parts of thermoplastic resin, 10 to 20 parts of organic fibers, 0 to 20 parts of inorganic fibers, 0 to 10 parts of other aids, and 20 to 40 parts of halogen-free flame-retarding master batch. The manufacturing method comprises: melting thermoplastic resin to obtain melt, immersing fibers into the melt of the thermoplastic resin, adding other aids into the melt, cooling the melt, and making fiber reinforced thermoplastic resin granules; and mixing the granules and the halogen-free flame-retarding master batch in batch to obtain the composite material. Compared with the prior art, the composite material manufactured by the method has high toughness, high strength and high rigidity, and has the characteristics of environment-friendliness, flame retardance, high thermostability, and low-temperature toughness. The thermoplastic resin composite material is an ideal novel laptop shell material.

Description

technical field [0001] The invention relates to a resin composite material and a manufacturing method thereof, in particular to a thermoplastic resin composite material used for a notebook computer shell and a manufacturing method thereof. Background technique [0002] With the rapid development of the notebook computer industry, the notebook computer casing is also developing in the direction of high strength, high rigidity and light weight. At present, most of the plastic casing notebook computers on the market are made of PC / ABS engineering plastic alloy. This material not only has the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, but also has the excellent processing fluidity of ABS resin. However, with the development of notebook computers, the comprehensive mechanical properties of PC / ABS alloys are not ideal due to factors such as protecting fragile electronic components and strengthening the strength of the overall s...
