Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides incense sticks and mosquito coils which are made by adding salts, sugar alcohols or phosphates to improve the viscoelasticity and stringiness of the water-soluble polysaccharide and the water-soluble polysaccharide solution. The present invention relates to a binder composition.

Traditionally, tab powder, cedar powder, wood flour, pine resin, etc. have been used as binders for incense sticks and mosquito coils, and depending on the manufacturing conditions, shofu paste, starch, and carboxymethyl cellulose (CMC) may be used as supplements. It is blended.

Among these binders, tab powder is the most important in the production of incense sticks.

Tab powder is a powder obtained by collecting and drying the bark and leaves of the tab tree, which is an evergreen tree of the family Tab, which grows naturally in temperate climate regions such as western Japan and Southeast Asia.

When this tab powder is made into an aqueous solution, it has very high viscoelasticity.
It has excellent stringability.

The viscoelasticity and stringiness of this tab powder performs extremely important functions in the kneading and molding processes of incense stick manufacturing.

If the viscoelasticity of the binder used to manufacture incense sticks is low, the dough after cross-crossing will lack strength, making it difficult to mold, and making it impossible to obtain incense sticks with a uniform linear or spiral shape.

Furthermore, if the binder has low stringability, the fabric after being mixed will be hard and brittle, making it difficult to form the fabric.

Especially in the case of incense sticks, they are manufactured by extruding or pulling them into a linear shape, so if they lack stringiness, the wires will break during production.
This will reduce manufacturing efficiency.

The unique viscoelasticity and spinnability of tab powder are essential in the production of incense sticks, and even today, when modern chemical industry has produced various water-soluble binders, it is still widely used as an excellent binder for incense sticks.

However, the viscoelasticity and stringiness of tab powder are greatly affected by the growing conditions of the tab tree, the growing region, drying and powder manufacturing methods, and it is extremely difficult to constantly obtain powder of constant quality.

The unstable quality of tab powder makes it difficult to produce incense sticks of consistent quality.

Furthermore, an aqueous solution of tab powder is unstable, and its viscoelasticity and stringiness tend to decrease over time.

In particular, it is unstable to changes in conditions such as mechanical shearing and temperature in the process of manufacturing incense sticks, and under these conditions, the viscoelasticity and spinnability of the tab powder solution are significantly reduced.

Therefore, in the manufacture of incense sticks, skilled engineers select and adjust conditions such as mixing time, kneading temperature, mixing speed, etc. based on their experience and knowledge while observing the properties of tab powder.

If you do not have enough experience and knowledge about the properties of tab flour, you may accidentally lengthen the kneading time or increase the kneading temperature.
If the kneading speed is increased, the viscoelasticity and spinnability of tab powder will be destroyed, making it extremely difficult to manufacture incense sticks.

Furthermore, if the kneading speed is too low, uniform mixing cannot be achieved, resulting in poor molding performance and roughness on the surface of the product.

The properties of tab powder also reduce the manufacturing efficiency of incense sticks, making it difficult to manufacture incense sticks of a certain quality.

Tab flour itself is inexpensive, but because of its unstable quality and properties, there has been a strong desire for a stable water-soluble binder of constant quality to replace Tab flour for manufacturing purposes.

Generally, water-soluble binders used in the industrial field include synthetic polymers and polysaccharides.

Examples of water-soluble synthetic polymers include polyvinyl alcohol sodium polyacrylate, polyacrylamide, polyethylene oxide, polyvinylpyrrolidone, carboxyvinyl polymer, polypropylene oxide, vinyl acetate, and styrene maleic acid copolymer.

Among these synthetic polymers, polysodium acrylate, polyethylene oxide, carboxyl vinyl polymer, etc.
．． When the aqueous solution concentration is 5% or more, it exhibits viscoelasticity and stringiness similar to an aqueous solution of tab flour, but like tab flour, it is unstable to mechanical shearing force and has poor viscoelasticity and stringiness. descend.

Furthermore, it was found that it is unsuitable as a binder for incense sticks because it gives off a bad odor or strange odor when burned.

Additionally, if 30% or more of a water-soluble polymer such as polyethylene oxide, which has excellent spinnability and viscoelasticity, is added alone to the incense stick raw material, it will become sticky after molding, and the incense sticks will re-stick before drying. There is a drawback.

Water-soluble polysaccharides include anionic and nonionic gum arabic, yam mucilage, Malapa chestnut mucilage, arabinogalactan, tragacanth gum, almond gum, carrageenan, sodium alginate, potassium alginate, propylene glycol alginate, alginate mallow, and alginic acid. Soda and calcium mixture, xanthan gum, pullulan, gum fins seed gum, laminarin, hectin, succinoglucan, xanflorifer cerelan, curdlan, carboxymethyl cellulose, carboxymethyl starch, carboxymethyl galactomannan, phosphorylated galacto Mannan, sodium cellulose sulfate, starch, agar, guar gum, locust bean gum, konjac, tamarind, scleroglucan, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxyethyl starch, hydroxypropyl galactomannan, carboxymethyl hydroxyprobyl These include galactomannan, starch phosphate, and tara gum, as well as cationic chitin, chitozan, hydroxytriammonium alkylgalactomannan, hydroxyethyltriammonium alkylcellulose, amine alginate, and black yeast-produced polysaccharide.

These water-soluble polysaccharides are stable to mechanical shear;
The viscoelastic properties and stringability of the solution are hardly reduced by stirring or cross-mixing.

However, when cationic water-soluble polysaccharides are burned,
Similar to water-soluble synthetic polymers, incense sticks are unsuitable for use as binders because they generate off-taste or bad odors originating from the amines in their chemical structures.

Anionic or nonionic water-soluble polysaccharides do not emit any off-odor when incense sticks are burned, and depending on the type, the solution has relatively high viscoelasticity or stringability.

For example, sodium alginate, quinseed gum, spider, etc. have excellent stringiness, but their stringiness is inferior to tab flour, and they are also inferior in viscoelasticity.

Xanthan gum, agar, konjac, carrageenan, etc. are highly viscoelastic, but are inferior to tab flour and lack stringiness.

Therefore, when these water-soluble polysaccharides are used alone, the viscoelasticity and stringiness that can be substituted for tab flour are not observed.

Although it was found that the combination of water-soluble polysaccharides improves viscoelasticity and stringiness, it is not possible to replace tab flour.

For example, the viscoelasticity was improved by blending xanthan gum and locust bean gum, and the stringiness was synergistically improved by adding quince seeds to this, but both the viscoelasticity and stringability matched the performance of tab flour. It wasn't something.

Furthermore, even if the combination of xanthan gum, hydroxypropyl galactomannan, carrageenan, ash, and quince seed synergistically improved viscoelasticity and stringiness, it did not completely replace the performance of tab flour. .

If a large amount of the mixture of these polysaccharides is added to the incense stick raw material, the viscoelasticity and stringiness will be similar to that of tab powder, but the problem of stiffness will arise as with synthetic polymers.

The present inventors conducted various studies in order to impart stringiness and viscoelasticity to these water-soluble polysaccharides. As a result, by using salts and sugar alcohols or phosphates in combination, viscoelasticity equivalent to the properties of tab flour was obtained. It was found that good stringability and stringability could be obtained.

We have found that combining salts with water-soluble polysaccharides improves the viscoelasticity, especially the elasticity, of the solution.

We have found that adding sugar alcohols or phosphates to polysaccharides improves the stringiness of the solution.

Among various salts, those that are effective as viscoelasticity improvers for polysaccharide solutions include potassium, magnesium, calcium, barium, manganese, iron, nickel, copper, zinc, boron,
These are inorganic or organic salts containing aluminum and/or silicon, and these salts can be used alone or in combination of two or more.

Examples of these salts include calcium carbonate, calcium phosphate, calcium pyrophosphate, calcium sulfate, calcium metasilicate, sodium metasilicate, barium sulfate,
Magnesium carbonate, manganese carbonate, aluminum oxide,
Iron oxalate, iron carbonate, nickel carbonate, ferric phosphate, zinc borate, calcium borate, sodium borate, methyl borate, ethyl borate, nickel borate, barium borate,
Examples include magnesium borate, boric acid, silver borate, manganese borate, lithium borate, calcium salicylate, calcium gluconate, calcium citrate, calcium dimaleate, calcium succinate, calcium tartrate, and calcium lactate.

Sugar alcohols that improve the stringiness of water-soluble polysaccharides include glycerin, erythritol, arabitol, ribitol,
These include xylit, sorbit, mannit, trait, hexit, ijit, and talit.

In addition, as phosphates that improve the stringiness of water-soluble polysaccharides like sugar alcohols, inorganic phosphoric acids such as sodium hexametaphosphate, sodium tripolyphosphate, sodium tetrapolyphosphate, potassium tetrapolyphosphate, potassium pyrophosphate, and sodium pyrophosphate can be used. There are salts, and these salts can be used alone or in combination of two or more.

The amount of salts added that improves the viscoelasticity of the water-soluble polysaccharide is 0.001 to 50% based on the weight of the water-soluble polysaccharide, and the amount of sugar alcohol or phosphate that improves the stringiness is also the same <0. A range of 0.001 to 50% is suitable.

The amounts added vary depending on the combination of two or more types of salts, the combination of two or more types of sugar alcohols or phosphates, and the combination of sugar alcohols and phosphates.

Examples of combinations of water-soluble polysaccharides, salts as viscoelasticity improvers, and sugar alcohols or phosphates as stringability improvers will be shown below based on the spirit of the present invention.

Table 1 shows the fluidity, elasticity, spinnability, viscosity stability against shearing, viscosity stability against temperature, and odor during film combustion of tab powder, various water-soluble synthetic polymers, and various water-soluble polysaccharides. This is a comparison of the following.

These results show that tab flour lacks viscosity stability against shear force and temperature.

Synthetic polymers such as polyethylene oxide lack viscosity stability against shearing forces, and also produce an off-odor when burned.

Cationic water-soluble polysaccharides such as chitosan are stable against shear forces, but an off-flavor was observed when burned.

Water-soluble polysaccharides such as pectin are stable against shear forces, and do not lose viscosity due to hydrolysis even when heated.
Although no unusual odor was observed during combustion, it was inferior to tab powder in terms of elasticity and stringiness.

Next, salts as an elasticity improver and sugar alcohols or/and phosphates as a stringability improver were added to the water-soluble polysaccharide for which no off-odor was observed during combustion in Table 1, and the same as in Table 1 was added. compared.

The following is a summary.

This is shown in Table 2. As a result, all items have the same viscoelasticity and stringiness as tab flour due to the selection and combination of water-soluble polysaccharides and the combination with salts and sugar alcohols or phosphates. A binder composition with excellent mechanical shear stability and temperature stability, which were disadvantageous, was obtained.

Even if salts, sugar alcohols, or phosphates are added to water-soluble polysaccharides individually, they do not provide the viscoelasticity and stringiness of tab flour, but by using them together, the performance of tab flour can be improved through a synergistic effect. I have something to show.

When this binder composition was actually blended into incense sticks, the incense sticks were always of uniform quality, and there was no difference at all from incense sticks containing Tab powder, which were produced with great care.

In addition, incense sticks could be manufactured with a lower additive amount than tab flour.

Next, Table 3 shows the conventional formulation and the binder compositions of Examples 1 and 2 of the present invention, and A and B are the conventional formulations.

In addition, Table 4 shows comparative tests of incense sticks obtained by adding 50 kg** of water to the compositions of each of these formulations, kneading them, extruding them into linear shapes using an extruder, and drying them in the sun. .

The results show that the binder composition of the present invention had a binder effect in a smaller amount than tuff flour, and the properties of the product were the same as those of conventional products.

Similarly, Table 5 compares the binder composition of the conventional mosquito coil formulation C1D and the mosquito coil of the present invention (shown in Examples 3 and 4).

After adding 100 kg of water to each of the above-mentioned compositions and kneading them, they were extruded into a belt shape using a punching machine, punched out into a spiral shape, dried in the sun, and used for comparative tests.

The results of the comparative test were the same as in Table 4 above (equivalent to the conventional product).
