Description

(54) A METHOD FOR MAKING A COOLING MIXTURE for processing, and to have a reduced solubility as a result of the reaction of all or some of the residual hydroxyl groups with agents that cause crosslinking. As such agents, dimethylol urea formaldehyde resins, melamine formaldehyde resins and other substances in amounts up to 5%, preferably from 0.001 to 0.500% of the total weight of the composition can be used. It is also possible to use organic salts, halide compounds having two or trivalent ions, such as iron or aluminum, to form crosslinks. For the preparation of the mixture, non-toxic substances are used as fillers, having a minimum particle size of from about 0.2 µm to 0.1 mm, preferably from 0.20 µm to 0.05 mm. Preferred fillers are materials having a coefficient of thermal conductivity at 800 ° C of more than 6-10 cal cm / sec ° C cm, for example, carbonates, oxides, silicates, aluminosilicates, alkali and alkaline earth metal aluminates, and aluminum hydroxide. Inorganic compounds in a natural state are suitable, for example, dolomite limestone, infusorial earth, magnesite, perlite, vermiculite, etc., as well as elements such as coal, zinc, magnesium, titap, aluminum, iron. Fillers can be either granulated or fibrous. As the latter, fiberglass, mica, asbestos, metal, metal oxide and metal carbide in fibrous form, such as aluminum chips, are used. The length of the fibrous material is from 0.1 to 5 mm. These nanofillers are displaced with a combustible product in a ratio of 15:85 to 85:15, most preferably a ratio of 25: 75 to 75:25. By displacing these components and water, a product has a smoldering rate comparable to that of tobacco smoldering. under similar conditions, i.e. about 5-10 mm / min, in the form of an ordinary cigarette. This rate of smoldering corresponds to 12–5 puffs of smoke when smoking a cigarette at a 60-second cycle. The smoking mixture obtained according to the described method can be used to replace tobacco in whole or in part. In this case, the ratio of tobacco and smoking mixture is most often in the range from 95: 5 to 25: 75. The products obtained by the proposed method produce smoke that does not have odor and taste. To make a mixture of smoking, taste and smell, tobacco extracts, fruit extracts, synthetic substances that give aroma, natural gums, sugars, as well as in controlled amounts nicotine and other alkaloids can be added. Example 1. 140 ml of deionized water at 80 ° C and 12.6 g of rutile (high grade titanium dioxide) are introduced into the mixer. To the resulting dispersion was added 8.4 g of sodium carboxymethyl cellulose with an average degree of substitution of 0.7. After 5-10 minutes, the film is cast on a Teflon-coated fabric, dried in an air oven at 125 ° C. Then, after drying and conditioning, the film is stretched to an average width of 0.9 mm and an average length of 1.0 mm. The cigarettes are made of cigarettes with a diameter of 8 mm and a length of 85 m, which are “smoked on the apparatus. The results in comparison with those obtained when smoking tobacco are given in table. 1. Table 1 As can be seen from the data table. 1, when the abacus is replaced by a smoking mixture, the amount of tar is reduced. Example 2. The preparation of the film are about example 1, except that as carboxymeloxyethyl cellulose and infusorial earth are used as ingredients. The data obtained are given in Table. 2. Table 2 Example 3. The film is prepared from three components: carboxymethylcellulose, dolomic limestone, and titanium dioxide. Cigarettes were prepared analogously to Example 1. The data are listed in Table. 3

Example 4. A film is prepared consisting of 37% carboxymethyl cellulose, 37% dolomite limestone, 10% coal and 16% wetting eeuJtecTBa, plasticizer and coloring agents. Take a mixture of tobacco and film (50:: 50), a mixture of tobacco and powdered synthetic material (50: 50). The amount of organic components in the gas phase is determined by gas chromatography. In tab. 4 shows the results, expressed in μg / club smoke.

In addition, the content of hydrogen cyanide, phenol, oxycarbon, and benzopyrene is determined for film, film, and tobacco, as well as for tobacco. The results are shown in Table. five.

Table 5 Example 5. Samples A - E are prepared. Their composition is given in Table. 6, and the indicators of the content of wet and dry resin obtained in the test carried out according to the method

The data obtained for the organic components of the gas phase (in µg / smoke) is given in table. eight.

Table 8

45 Indicators of the organic gas phase obtained when testing mixtures containing two components in combination with tobacco are significantly lower than the indicators for tobacco. When combined use of the combustible component, filler and tobacco, they are lower than when using only the combustible component and tobacco or filler and tobacco. In addition, the values obtained with the use of film and tobacco fibers in the form of a mixture (sample E) are lower than when tobacco was introduced into the film (sample E).
