preparation example Construction

[0058] The preparation method of the fully degradable cooling firmware of the present invention comprises the following steps:

[0059] (1) Obtain a variety of fully degradable materials and mix them, and add a solubilizer during the mixing process to obtain raw materials for granulation.

[0060] (2) Extrude and granulate the raw materials used for granulation by extrusion and granulation process to obtain fully degradable cooling masterbatch.

[0061] In a specific embodiment, drying a variety of fully degradable materials can effectively remove moisture and prevent the hydrolysis and cracking of raw materials during subsequent heating and melting. Wherein, the drying temperature is 60-80 degrees Celsius. The drying time is 2 to 4 hours.

[0062] In a specific embodiment, hot air is used to dry a variety of fully degradable materials, which is simple and efficient, and has a good drying effect.

[0063] In a specific embodiment, the raw materials are extruded and granulat...

Embodiment 1

[0114] Example 1: Preparation of Cooling Masterbatch

[0115] Select polylactic acid, polycaprolactone, thermoplastic polyester elastomer, copolymer of butylene adipate and butylene terephthalate, polybutylene succinate, polypropylene and polyethylene 2 to 4 kinds to obtain a variety of fully degradable materials. It is blended according to a certain proportion and dried. During the mixing process, PR023-7, ADR, 115C, isopropanol, maleic anhydride, and epoxy compatibilizers are added with a mass fraction of 0.3% to 1.5%. Agent, polyethylene glycol, polycaprolactone as a solubilizer to form raw materials for granulation. The raw materials are placed inside the twin-screw extruder for melt plasticization and extrusion to form a cooled masterbatch parison. Use the air-cooled conveyor belt to transfer the cooled masterbatch parison to the granulator for pelletizing.

[0116] Further, the drying temperature is 60-80 degrees Celsius.

[0117] Further, a high-level mixer is used ...

Embodiment 2

[0127] Embodiment two: the preparation of cooling tube

[0128] The cooling tube is prepared by polylactic acid (E-1300), a copolymer of butylene adipate and butylene terephthalate, including the following steps: purchase vacuum-packed biodegradable plastics, which can be used directly after opening the package, If it is not used up after opening the package, it should be sealed again for storage. The biodegradable plastic is prepared into a cooling masterbatch, and the cooling masterbatch is placed in the extruder 3 for melting, plasticizing and extruding to form a cooling tube parison. Wherein, the temperature of the material delivery part in the extruder 3 is kept at 140 degrees Celsius, the temperature of the material melting part in the extruder 3 is kept at 150 degrees Celsius, and the temperature of the melt delivery part in the extruder 3 is kept at 160 degrees Celsius. The temperature of the homogenizing conveying part in the machine 3 is kept at 165 degrees Celsius,...

Abstract

The invention discloses a fully-degradable cooling firmware and a preparation method and application thereof. The fully-degradable cooling firmware comprises a cooling master batch which is used for reducing the temperature of flue gas and can be fully degraded. The cooling master batch is prepared from a plurality of fully degradable materials and a solubilizer. The preparation method of the fully-degradable cooling firmware comprises the following steps of: obtaining and mixing the various fully-degradable materials, and adding the solubilizer in the mixing process to obtain a raw material for granulation; and carrying out extrusion and granulation treatment on the raw material by adopting an extrusion and granulation process to obtain the fully-degradable cooling master batch. The invention discloses application of the fully-degradable cooling firmware in a cooling filter stick for a heat-not-burn cigarette. The application comprises the application of the cooling master batch in the cooling filter stick; and / or an application of a cooling pipe in the cooling filter stick. The temperature of smoke at the inlet end of a heat-not-burn cigarette can be effectively reduced, and meanwhile the suction resistance and the filtering efficiency of the cooling filter stick are not affected.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a fully degradable cooling firmware and a preparation method and application thereof. Background technique [0002] When smoking HNB (heat not burn) products, the smoke in the filter rod is in the state of aerosol (aerosol particles in the state of tiny liquid droplets). Since the size and composition of aerosol particles are directly affected by the temperature of the smoke, the harmful components of the smoke and the sensory quality of HNB cigarettes will also be affected by the temperature of the smoke. After the tobacco component in the heat-not-burn cigarette is heated by a heating device at about 250-350° C. (Celsius), nicotine and some aromatic substances will be fully released. However, due to the short length of cigarettes and poor heat exchange efficiency of heat-not-burn cigarettes, the temperature of the smoke at the inlet is usually relatively high, and ...
