The disclosure relates to the technical field of cigarette filters, and particularly to a harm-reducing cigarette filter, and its preparation method and application.
It is universally known that smoking is harmful to health. In order to reduce the harm of smoking to health, many scientists are trying to find ways and design thousands of cigarette additives, filter cotton, filters and other products. Through filtering, adsorption and other intervention measures, these products can indeed reduce some of tar, nicotine and other harmful substances, but the disadvantage is that the serious carcinogens in cigarettes cannot be completely filtered out. On the basis of the prior art, developing a cigarette additive and a cigarette filter which can not only filter most of the tar, nicotine, phenol and crotonaldehyde, but also decompose and convert benzopyrene, nitrosamine, carbon monoxide, hydrogen cyanide, ammonia and other carcinogens and gases, and at the same time have the functions of space antibacterial, inactivating virus, preventing cold, pharyngitis, pneumonia, rhinitis, oral inflammation, purifying air, reducing the harm of smoking to human body and reducing the harm of second-hand smoke to other people, has a broad market space and creates huge economic value.
Based on the above reasons, the applicant obtained a new cigarette filter after several creative efforts. The cigarette filter includes six layers from outside to inside: a first layer includes filter cotton with an activated carbon, a second layer includes a five-hole glue, a third layer includes filter cotton, a fourth layer includes filter particles, a fifth layer includes filter cotton with filter fluid, and a sixth layer includes a silica gel cover. The cigarette filter is injection molded by utilizing non-toxic polycarbonate (PC) or polymethylmethacrylate (PMMA). The experimental research shows that the cigarette filter of the disclosure has good adsorption effect on tar and nicotine, and reduces smoking people to absorb harmful substances.
The PC is a strong and tough thermoplastic resin with the characteristics of colorless transparency, heat resistance, impact resistance, flame retardancy, high refractive index, and good processing performance.
The PMMA is a kind of high molecular polymer and also known as acrylic or plexiglass. The PMMA has the advantages of high transparency, low price, easy machining, and is often used as a substitute for glass.
The disclosure is implemented through the following technical solutions.

An adsorption effect of the cigarette filter on tar and nicotine in cigarettes.
An experimental method is as follows: commercial Zhongnanhai (soft boutique) cigarettes (tar content 10 milligrams per cigarette abbreviated as mg/cig, nicotine content 0.9 mg/cig) are bought and divided into different experimental groups:
The cigarettes with the cigarette filters of different groups are put into Borgwaldt KC RM200A smoking machine in turn and burned. After the burning, the tar content and nicotine content in each cigarette filter is detected and an average value is calculated. As shown in Table 1 for the experiment results.
Experimental conclusion: the above experiment shows that the cigarette filter of the disclosure has a good adsorption effect on tar and nicotine in cigarettes. Compared with commercially available cigarette filters and cigarette filters of comparative embodiments, the cigarette filter of the disclosure can significantly decrease the tar and nicotine content in the mouth of smokers and adsorb more than 80% of tar and nicotine in cigarettes. This fully demonstrates that the cigarette filter of the disclosure has scientific significance.
