With the development of market economy, commodity competition is becoming increasingly fierce. While improving product quality, enterprises increase the ancillary functions of products and strive for product innovation, novelty and beauty. It has become a new direction of product competition. Aromatic plastic products are one of them.
It is to add flavouring agent in the process of product molding and processing, so that plastic and other products can emit aromatic smell when in use, give people a fresh, comfortable and fresh feeling, and cover up the peculiar smell inherent in the resin or generated in the processing process. Increasing the use value of plastic products can stimulate customers' desire to buy, so as to achieve the purpose of winning by surprise in the fierce market competition.
Aromatic masterbatch is a mixture with high concentration of aromatic chemicals uniformly dispersed in thermoplastic resin base material. High efficiency directional plastics are mainly composed of carrier resin, flavor enhancer and additive. Through certain formula and processing technology, the flavor is evenly dispersed in specific carrier plastics. Plastics are high molecular polymers with large molecular weight and wide molecular spacing. In the molecular structure of plastics, there are crystal regions with regular arrangement of molecules, amorphous regions with disorderly arrangement, and some also contain polar groups, which is conducive to infiltrating the effective components of flavor enhancers into plastic molecules by physical or chemical methods to form a multiphase with close structure between flavor enhancers and polymers. Due to the permeability and volatility of low molecular substances, And compatibility, so that the flavouring agent in the plastic continuously diffuses from high concentration to low concentration, and then volatilizes from the surface to the environment, emitting aromatic smell, so as to achieve the purpose of long-term fragrance dispersion.
flavouring agent is the main component of aromatic plastic masterbatch. It is an aromatic substance used to increase or improve the aroma of materials. According to its structure, it can be roughly divided into esters, alcohols, aldehydes and carboxylic acids. Due to different varieties, the heat resistance and compatibility with resin are also different. The processing and molding temperature of common resins is above 150 ° C. Therefore, it must be selected with good temperature resistance, not easy to react with resins and other additives, less dosage, no toxicity, and certain compatibility with base resin.
