Problems solved by technology

[0004] In order to obtain materials that can emit fragrance, the traditional method is to make the fragrance adhere to the surface of the plastic product by spraying or soaking, or to mix the fragrance before injection molding, and the plastic used is generally a general-purpose plastic with low processing temperature and low performance. Satisfies demanding uses and does not have a long-lasting fragrance

Embodiment 1

[0032] Mix 2% essence by weight and 1% white oil in a plastic container to dilute the essence, then put PC 59.8%, ABS 26%, PC / ABS compatibilizer 3% and the diluted essence into the mixer and stir , so that the essence is evenly attached to the surface of the plastic particles, and then put B3388%, 1010 0.1%, and 168 0.1% into the mixer, and continue to mix at room temperature for 4 minutes. Afterwards, the mixed materials are put into the hopper of the twin-screw extruder, melted and blended, extruded and granulated to form a composite material. Among them, the temperature settings of each heating zone of the screw are as follows: zone 1 temperature: 220°C, zone 2: 230°C, zone 3: 230°C, zone 4: 220°C, head: 225°C, residence time <1min, pressure is 15MPa. The material sample has been placed for more than a year, and the fragrance is still unabated

Embodiment 2

[0034] Mix 0.5% essence by weight and 1% white oil in a plastic container evenly to dilute the essence, then put PC 92.3% and the diluted essence into the mixer and stir to make the essence evenly adhere to the surface of the plastic particles, and then put Put C223A 6%, 1010 0.1%, and 168 0.1% into the mixer, and continue mixing at room temperature for 4 minutes. Afterwards, the mixed materials are put into the hopper of the twin-screw extruder, melted and blended, extruded and granulated to form a composite material. Among them, the temperature settings of each heating zone of the screw are: zone 1 temperature: 235°C, zone 2: 240°C, zone 3: 240°C, zone 4: 230°C, head: 235°C, residence time <1min, pressure 15MPa. The obtained particles have a certain fragrance.

Embodiment 3

[0036] Mix 3% essence by weight and 1% white oil in a plastic container evenly to dilute the essence, then put PC 89.8% and the diluted essence into the mixer and stir to make the essence evenly adhere to the surface of the plastic particles, and then put Put C223A 6%, 1010 0.1%, and 168 0.1% into the mixer, and continue mixing at room temperature for 4 minutes. Afterwards, the mixed materials are put into the hopper of the twin-screw extruder, melted and blended, extruded and granulated to form a composite material. Among them, the temperature settings of each heating zone of the screw are: zone 1 temperature: 235°C, zone 2: 240°C, zone 3: 240°C, zone 4: 230°C, head: 235°C, residence time <1min, pressure 15MPa. The obtained particles have a strong and long-lasting fragrance.

Abstract

The invention discloses an engineering plastic capable of generating fragrant smells as well as process for preparation, wherein the constituents include (by weight ratio) engineering plastic 62-92%, flavoring agents 0.5-20%, toughening agent 6-10%, anti-oxidant 0.1-1%, white oil 0.5-2%, other auxiliary agents 0.1-5%.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a fragrance-emitting engineering plastic and a preparation method thereof. Background technique [0002] PC (polycarbonate) is a kind of polymer containing carbonate in the molecular chain. It is one of the five general-purpose engineering plastics. Its output and consumption are second only to nylon engineering plastics, ranking second. PC / ABS (polycarbonate / acrylonitrile-styrene-butadiene copolymer) alloy is the main variety of PC alloy and an important engineering plastic alloy. PC / ABS alloy is the world's largest commercial polymer alloy. Modified PC has excellent comprehensive performance and is widely used in the fields of automobile industry, electronic and electrical industry, machinery industry and so on. [0003] However, although PC materials and their alloys have a wide range of applications, because these materials themselves have no taste, and some may e...
