Definitions
- the present invention relates to a rubber odor and protein remover having the following effects and a method for removing the same. That is, the rubber odor contained in natural rubber, that is, disulfide carbon is removed by a diagonal reaction. It also removes proteins that cause allergies.
- Rubber includes natural rubber and synthetic rubber containing, for example, urethane resin as a main material. Natural rubber is cheaper than synthetic rubber.
- the physical properties of natural rubber and synthetic rubber (mainly made of urethane resin) are as follows!
- natural rubber contains protein because it is natural rubber. This protein causes allergies by contact with the skin. Allergies due to natural rubber proteins are specifically referred to as “latex allergies”. A “latex allergy” can be fatal to some people.
- products using natural rubber are required to indicate this fact.
- surgical gloves and condoms are subjected to a deproteinization treatment for reducing the content of the above-mentioned protein.
- deproteinization treatments for reducing the protein contained in natural rubber.
- Natural rubber products also have a unique odor, a so-called rubber odor. It is known that the cause of this rubber odor is disulfide carbon. Since disulfide carbon is perceived as a very intense off-flavor, it may cause discomfort or harm the user. In addition, disulfide carbon is very dangerous depending on the usage environment because of its high flammability. Therefore, the working environment of the natural rubber processing sector is in a poor state with discomfort and danger.
- Patent Document 1 for a method capable of simultaneously performing the above-described deproteinization treatment and removal of rubber odor!
- Patent Document 1 Japanese Unexamined Patent Publication No. 2003-24653
- Patent Document 1 describes that rubber odor and protein are eliminated as much as possible without impairing the properties of natural rubber. That is, Patent Document 1 removes proteins to 0.1% or less, expressed as the nitrogen content (N%) in the solid content.
- Patent Document 1 As a specific method in Patent Document 1, the following two methods are employed. 1) Decompose proteins with bacteria, enzymes and alkalis during the natural rubber latex production stage. After that, the decomposed and suspended proteins are removed with a surfactant. 2) Before the product is completed, immerse it in a solution of nocteria, enzymes and alkali to decompose the protein. Then, the decomposed and suspended proteins are removed with a surfactant.
- natural rubber is not suitable for applications that directly contact human sensitive parts such as medical gloves and condoms while pressing.
- the condition is not satisfied at about 700-900 ppm, and it is always desired to reduce it to about 50 ppm.
- Patent Document 1 discloses that the protein is reduced to 700 to 900 ppm or less regardless of the means. Patent Document 1 describes that removal of protein can remove rubber odor. In practice, however, reducing protein and removing rubber odor are separate tasks. That is, the cause of the rubber odor is disulfide carbon (described later). Therefore, even if the protein is reduced to 0.1% or less in terms of the nitrogen content (N%) in the solid content as in Patent Document 1, the rubber odor is not always removed. Regarding this point, Patent Document 1 does not clearly describe.
- a well-known masking method can reduce the odor to a level that can be tolerated.
- the molecular structure of disulfide carbon is a strong bonding state in which two carbon atoms are double-bonded to one carbon atom. Carbon disulfide is extremely chemically stable at room temperature, and is unlikely to react with ordinary oxidizing and reducing agents. In addition, disulfide carbon emits an offensive odor even at a very small concentration, so it is difficult to deodorize by a method such as masking.
- the removing material of the present invention is characterized in that the primary amine and the secondary amine simultaneously contain a malodorous and flammable disulfide carbon and a protein that causes allergy by a chemical reaction. Can be decomposed. Therefore, the removing agent of the present invention can surely remove protein and carbon dioxide (rubber odor). In addition, the removal method of the present invention can remove tanno and disulfide carbon by immersing for a predetermined time. Therefore, the removal method of the present invention can surely and simultaneously remove the protein and rubber odor very easily.
- the present invention is characterized in that a primary amine or a secondary amine conjugate is used as a main component.
- the removal of rubber odor is removed by the following principle.
- the main cause substance of the off-flavor of natural rubber products is sulfur conjugate. Among them, it is known that the contribution of carbon dioxide is large. Disulfide carbon is a very stable substance. Therefore, it is difficult to remove off-flavors caused by disulfide carbon using a conventionally known deodorant derived from a natural product, a general oxidizing agent or a reducing agent. In addition, the use of powerful chemicals in oxidizing and reducing agents is also difficult to remove easily because of safety restrictions.
- Patent Document 1 discloses that an “amine salt” is used.
- the “amine salt” in Patent Document 1 is used as a “surfactant” for decomposing proteins with nocteria, enzymes, and alkalis, and then removing decomposed and suspended proteins. And different.
- anionic surfactants are generally Is represented by the following structural formula (Formula 1).
- ammonia and amines are used instead of Na, and those having the following structural formulas (Chemical Formulas 2 and 3) are referred to as amine salts.
- the primary amine and the secondary amine have the following structural formulas (Chemical Formulas 4 and 5).
- the present invention uses a primary amine or a secondary amine as a main component of the removing agent.
- the primary amine or the secondary amine is a very natural reaction with disulfide carbon, that is, both react rapidly without any special treatment at room temperature. Further, the dithiol rubbamate produced in the above reaction is easily dissolved in water. Therefore, the equipment is not large-scale, and as will be described later, the rubber odor can be removed simply by immersing the natural rubber product immediately before completion for a predetermined time.
- the primary amine or the secondary amine is preferable by adopting the following.
- the aliphatic primary amines are butylamine, amylamine, hexylamine, heptylamine and octylamine.
- secondary amines dipropylamine, diisopropylamine, dibutylamine.
- Water-soluble monoethanolamine, diethanolamine, arylamine, diarylamine, alicyclic primary amine, alicyclic secondary amine, aromatic primary amine, and aromatic secondary amine can also be used. .
- triamines may be used. These triamines exhibit extremely high deodorizing ability at low concentrations. Further, the triamines can be present together with the polyhydric alcohols described below without causing unnecessary reactions or offsetting of the action.
- the removing agent of the present invention can surely remove the rubber odor simultaneously with the protein.
- the removing agent of the present invention for example, natural rubber gloves for operation, natural rubber condoms and the like can reliably remove rubber odor and protein. Can be removed.
- the removal method of the present invention is performed as follows in detail according to the product. For example, a solution of a primary amine or a secondary amine having a concentration of 0.01-5.0% and a polyhydric alcohol having a concentration of 0.05-0.5% is prepared. Keep the solution at 30-40 ° C and immerse it for 30-60 minutes To do. Then wash with running water at 30-40 ° C. Then dry at 40-60 ° C for 6-8 hours.
- the reason for setting the primary amine or the secondary amine conjugate in the solution to 0.01% to 5.0% is as follows. That is, if the concentration is lower than 0.01%, deodorization and deproteinization become insufficient. If the concentration is higher than 5.0%, extra time is required in the cleaning step. If the concentration is higher than 5.0%, unnecessary costs may increase. The same applies to the case where the concentration of polyhydric alcohols is set at 0.05-0.5%.
- the reason for setting the temperature of the solution of the removing agent to 30 to 40 ° C. is as follows. That is, if the temperature is lower than 30 ° C, the efficiency of deodorization and deproteinization decreases.
- the temperature may be set to a high temperature within a range where natural rubber does not deteriorate.
- the upper limit was set to 40 ° C in consideration of work safety. The same applies to the case where the temperature of the cleaning liquid is set to 30 to 40 ° C.
- the reason for immersing the natural rubber product in the above-mentioned remover for 30 to 60 minutes is as follows. That is, if the time is shorter than 30 minutes, deodorization and deproteinization become insufficient. Also, if the time is longer than 60 minutes, unnecessary costs may increase. The same is true for the cleaning time.
- the reason for drying at 40-60 ° C. for 6-8 hours is as follows. That is, if the temperature is lower than 40 ° C., the drying efficiency is poor and a long time is required. If the temperature is higher than 60 ° C, the material of natural rubber may be deteriorated. And if it is in this temperature range, the drying time is 6-8 hours, which is necessary and sufficient.
- the timing of immersion may be at any stage in the product manufacturing process using natural rubber, which is desirable immediately after purification in the latex refining process, for example. It is desirable to carry out in the step.
- the removing agent of the present invention used in the experiment is as follows.
- Example 1 Three types of condoms (Example 1, Example 2, Example 3) having a wall thickness of 43 ⁇ , 44 ⁇ m, and 45 ⁇ m using the above-described removing agent and the removing method, and the removal of the present invention No condensing agent (and removal method) was adopted. 4) was compared.
- Comparative Example 3 smelled or smelled easily, while Example 3 could detect (what odor) or not. However, rubber odor (and the odor generated from natural rubber products as a whole) could be removed to some extent.
- the present invention can remove a very small amount of the protein contained in natural rubber, which does not significantly impair the properties possessed by natural rubber itself.
- the odor was removed to such an extent that it was odorless.
