Embodiment 1

[0023] Prepare 100 kg of flavor masterbatch for plastics

[0024] 1. The weight percentage of each component is:

[0025] EVA 50 parts

[0026] Flavor 20 parts

[0027] SEBS 30 parts

[0028] 2. Preparation method:

[0029] Weigh the flavoring agent and flavoring absorbent according to the formula ratio, put the weighed flavoring agent and flavoring absorbent into the mixer and stir, the flavoring agent is completely absorbed and stirred to a uniform state, and then weigh it according to the weight ratio. Take the EVA carrier resin and add it to the hopper of the twin-screw extruder together with the above-mentioned uniformly mixed flavor-enhancing absorbent, melt and extrude, and granulate to prepare flavor masterbatches. The extrusion temperature is 100°C and the screw speed is 120r / min.

Abstract

The invention provides a preparation method of a high-concentration essence master batch, relates to a master batch capable of continuously releasing fragrance, in particular to a preparation method of a high-concentration essence master batch, and belongs to the field of high polymer material processing. The perfume is prepared from the following raw materials in parts by weight: 50-70 parts of carrier resin, 10-20 parts of a flavor enhancer and 20-30 parts of a flavor enhancing absorbent. The essence master batch prepared by the invention can be applied to various thermoplastic resin carriers; compatibility with substrate, the preparation method is simple, the mechanical property of the material is not influenced, the prepared material has lasting pure fragrance and is environmentally friendly and non-toxic, the service life of a fragrant plastic product is prolonged, the process steps in the prior art are simplified under the condition that the quality is not influenced, meanwhile,the process flow in the prior art is optimized, the perfuming effect is better, and the fragrance preservation time is long.

Description

technical field [0001] The invention relates to a masterbatch capable of continuously releasing fragrance, in particular to a method for preparing a high-concentration essence masterbatch, and belongs to the field of polymer material processing. Background technique [0002] Most plastic products emit some unpleasant irritating odors, which not only affect the environment of the job site during the manufacturing process, but also reduce people's use experience. With the continuous improvement of people's living standards, the need to use flavoring agents in daily life is becoming more and more common. Adding flavoring agents during the molding process of plastic products can not only cover up the inherent or produced in the resin. The peculiar smell can also make the product emit a fragrant smell when it is used, giving people a fresh, comfortable and fresh feeling, and adding the additional function of plastic products. The special fragrance can cover up the unpleasant sme...
