Particles capable of lowering temperature of smoke of cigarettes and preparation method and application of particles

Abstract

The invention belongs to the technical field of cigarette auxiliary materials and relates to particles capable of lowering the temperature of the mainstream smoke of cigarettes and a preparation method and application of the particles. The particles are inactive particles, active particles with outer film layers or inactive particles with outer film layers. The thickness of the outer film layers of the inactive particles is 0-0.2 mm, and the outer film layers account for 0-50% of the total particle mass; the thickness of the outer film layers of the active particles is 001-0.2 mm, and the outer film layers account for 0.001-50% of the total particle mass. The inactive particles are particles which adsorb 3.0 mg / cm<3> or less of nicotine in smoke aerosol; the inactive particles include inorganic particles or organic particles. The preparation method is simple, industrialization is convenient, and the particles are easily added into cigarette filter rods. The surfaces of the particles are dense and have no leakage, and by adding the particles into the cigarette filter rods, the temperature of the smoke of the cigarettes can be greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of cigarette auxiliary materials, and relates to a particle capable of reducing the temperature of cigarette mainstream smoke, a preparation method and application thereof. Background technique [0002] Cigarette is a special consumer product, and its consumption form is to enjoy its smoke by burning and smoking. Cigarette smoke refers to the highly concentrated and constantly changing aerosol system produced by the shredded tobacco in the lit cigarette through a complex combustion process. There are two forms of cigarette combustion: one is the combustion during smoking, which is called burning and smoking; the other is the burning in the suction gap, which is called smoldering (also known as static burning). [0003] The smoke drawn from the filter end of the cigarette during smoking is called the mainstream smoke (Main-stream Smoke, referred to as MS), and the smoke released from the burning end and diff...

Problems solved by technology

However, the problem is that when polylactic acid undergoes glass transition, it will melt or melt and bond. Therefore, the polymer material at the end of the most cooled end that first contacts the smoke will immediately undergo serious adhesion and collapse, blocking the pores and making the smoke Air cannot flow smoothly through the pleated polymer interior, reducing the cooling surface area and resulting in excessively high flue gas temperatures
