Problems solved by technology

Starting from other properties, the pH regulator used in this patent is a very weak Lewis acid, which is added in a large amount and is likely to affect other properties (such as impact strength and stress cracking properties)
Triphenyl phosphite, sodium dihydrogen phosphate, and sodium dihydrogen phosphite are in the form of solid powder or fine particles. Due to the small amount, it is difficult to disperse evenly in the alloy, which brings difficulties to processing

Embodiment Construction

[0045] The present invention is further illustrated by the following examples, but the present invention is not limited by the following examples.

[0046] The sources of the raw materials used in the present invention are as follows, but are not limited by the following raw materials.

[0047] Source of silver ions: silver ion antibacterial agent, IKM50G, Japan Jieermei;

[0048] Liquid acid: phosphoric acid;

[0049] Flame retardant A: phenoxyphosphazene;

[0050] Flame retardant B: bisphenol A bis (diphenyl phosphate);

[0051] Flame retardant C: melamine polyphosphate;

[0052] Lubricant: stearate lubricant, PETS;

[0053] Example Preparation method of polycarbonate alloy: According to the proportion, add polycarbonate, ABS resin, silver ion antibacterial agent, porous foamed polycarbonate with liquid acid or porous foamed ABS, and flame retardant into high-speed mixing. Mix evenly in a feeder, then add it to a twin-screw extruder, melt and mix at a temperature of 230...

Abstract

The invention discloses a polycarbonate alloy, which is characterized in that, in parts by weight, it comprises the following components: 70 parts of polycarbonate; 1-60 parts of ABS resin; the pH value of the polycarbonate alloy is 6.3-6.9, pH is adjusted by liquid acid. By adjusting the pH value of the polycarbonate alloy, the present invention ensures that the polycarbonate alloy of the present invention has the advantages of better damp-heat stability, wider processing window and the like.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a polycarbonate alloy and a preparation method thereof. Background technique [0002] At present, polycarbonate (PC) is widely used in the production of various industrial and civil parts (such as various transparent parts, lamp shades, instrument panels, etc.). With the improvement of living standards, people pay more and more attention to health. In order to avoid the reproduction of bacteria in plastic parts and improve the safety of products, the requirements for plastics to inhibit bacterial reproduction are becoming more and more stringent. [0003] In PC / ABS alloy, the polymerization residual impurities caused by raw materials cannot be avoided, and the residual impurities will greatly deteriorate the stability of the alloy. This is because the emulsifier added in the production process will remain in the ABS resin and cause cracking of the system. eff...
