Problems solved by technology

[0004] Although the prior art uses polyethylene terephthalate-1,4-cyclohexanedimethanol ester to modify PC, its products have poor performance in terms of fluidity, warpage performance, internal stress performance, and mold release performance. , color and other aspects failed to achieve good results, especially as a thin-walled product, the above-mentioned lack of performance is particularly obvious

preparation example Construction

[0104] In embodiment and comparative example, the preparation method of described PC alloy material, comprises the steps:

[0105] 1) Weigh each component according to the formula content, and mix the polycarbonate, polyethylene terephthalate-1,4-cyclohexanedimethylene ester, fibrous filler, and other additives that need to be pre-dried Perform pre-drying treatment at 120°C to 130°C, and set the pre-drying time to 4h to 6h to obtain pre-dried polycarbonate, polyethylene terephthalate-1,4-cyclohexanedimethanol Esters, fibrous fillers, other additives;

[0106] 2) Mix the pre-dried polycarbonate, polyethylene terephthalate-1,4-cyclohexanedimethanol, fibrous fillers, and other additives through a high-speed mixer, and the mixing temperature is 30℃~50℃, the mixing time is set at 5min~15min;

[0107] 3) Mix homogeneously mixed polycarbonate, polyethylene terephthalate-1,4-cyclohexanedimethanol, other additives, aluminum salt or aluminum oxide, copper salt or copper oxide, Zircon...

Embodiment 33

[0116] Embodiment 33: The way of adding glass fibers in 3) is: based on the total weight of glass fibers, the glass fibers accounting for 40% of the total weight of glass fibers are added from the feeding port 1 in the figure, based on the total weight of glass fibers, accounting for 40% of the total weight of glass fibers. The glass fiber of 35% of the total weight of the glass fiber is added from the feed port 2, based on the total weight of the glass fiber, the glass fiber accounting for 25% of the total weight of the glass fiber is added from the feed port 3. In the obtained pellets, glass fibers with a length of 100um to 300um account for 40% by weight of glass fibers; glass fibers with a length greater than 300um but not more than 500um account for 25% by weight of glass fibers.

Embodiment 34

[0117] Example 34: The glass fiber is added in the following manner in 3): based on the total weight of the glass fiber, the glass fiber accounting for 20% of the total weight of the glass fiber is added from the feeding port 1 in the figure, based on the total weight of the glass fiber, accounting for 20% of the total weight of the glass fiber. The glass fiber of 35% of the total weight of the glass fiber is added from the feed port 2, based on the total weight of the glass fiber, the glass fiber accounting for 45% of the total weight of the glass fiber is added from the feed port 3. The glass fibers with a length of 100um to 300um in the obtained pellets account for 60% by weight of the glass fibers; the glass fibers with a length greater than 300um but not more than 500um account for 25% by weight of the glass fibers.

Abstract

The invention discloses a PC (polycarbonate) alloy material. The PC alloy material is prepared from components in parts by weight as follows: 54-91 parts of PC, 4-61 parts of poly(ethylene glycol terephthalate-co-1,4-cylclohexylenedimethylene terephthalate), larger than 0 and not more than 32 parts of fibrous filler and 0-6 parts of other auxiliaries. Polyester is adopted to modify PC alloy, so that the obtained PC alloy material overcomes defects of existing PC alloy materials, has good fluidity, warping property, internal stress, demoulding property and color and is particularly applicable to preparation of thin-wall products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC alloy material and its preparation method and application. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent performance. It has good comprehensive properties, high mechanical strength, good impact toughness, stable size, and good electrical insulation; but PC also has high melt viscosity, poor fluidity, and solvent resistance. Poor resistance, prone to stress cracking and swelling in solvents and alkaline environments, more sensitive to notches, prone to stress cracking during processing, and the processing temperature is higher. It is a relatively effective and convenient modification method to select special polyester to improve the performance of PC and obtain composite materials with excellent comprehensive properties. [0003] Polyethylene terephthalate-1,4-cyclohexanedimethanol has high impact strength, outstanding tr...
