preparation example Construction

[0014] The preparation method of the polycarbonate composition with antibacterial function comprises the following steps:

[0015] (1) After weighing each constituent raw material according to the formula ratio, place it separately;

[0016] (2) Preheat the polycarbonate to 90°C and set aside;

[0017] (3) Cedar wood oil, nano-silver oxide, Cathone, triethanolamine, isothiazolinone, 2-hydroxyethylamine, pentachlorophenol, omethoate, imidacloprid, cypermethrin, 8-hydroxyquinoline copper, asphalt horseshoe Grease, 4-dipalmitoylproline, cyanoacrylate, crotonaldehyde, copper sulfate pentahydrate, Thiobacterium copper, oxazolidinones, bis-imidazolidinyl urea were put into the mixer, at a temperature of 102 ℃ After stirring at a speed of 90r / min for 50min, then put the plasticizer and antistatic agent into the mixer, and at a temperature of 105°C, stir at a speed of 85r / min for 60min and set aside;

[0018] (4) Put the materials of steps (2) and (3) together into a twin-screw extr...

Abstract

The invention provides a polycarbonate composition with an antibacterial function and relates to the technical field of high polymer materials. The polycarbonate composition is prepared from the following raw materials: 95 to 110 parts of polycarbonate, 25 to 30 parts of cedarwood oil, 10 to 15 parts of nano silver oxide, 15 to 20 parts of 5-chloro-2-methyl-4-isothiazolin-3-one, 14 to 22 parts of triethanolamine, 8 to 15 parts of isothiazolinone, 9 to 17 parts of 2-hydroxyethylamine, 3 to 7 parts of pentachlorophenol, 2 to 8 parts of omethoate, 1 to 4 parts of imidacloprid, 14 to 19 parts of cypermethrin, 11 to 20 parts of copper 8-hydroxyquinoline, 5 to 12 parts of asphalt mastic, 8 to 14 parts of 4-dipalmitoyl hydroxyproline, 14 to 19 parts of cyanoacrylate, 20 to 25 parts of crotonaldehyde and 15 to 23 parts of copper sulfate pentahydrate. The polycarbonate composition provided by the invention has the beneficial effects that the raw materials are low in price, and a preparation process is simple; the prepared polycarbonate composition has the functions of inhibiting and killing bacteria.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polycarbonate composition with antibacterial function. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Polycarbonate resin is known for its excellent impact resistance, dielectric properties, high heat resistance, high dimensional stability, high transparency, high flame retardancy, UV radiation resistance, coloring properties, FDA compliance, easy reinforcement and The physical modification potential of chemical modification has rapidly formed a global commodity, and its production scale is also increasing. It has become the second largest engineering plastic after polyamide (PA), and is widely used in electronics, electrical appliances, and automo...
