Glass Wool Scattering Agent

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass wool scattering inhibitor, and more particularly, to a glass wool scattering inhibitor used when molding glass wool into a sound absorbing heat insulating material.

In buildings such as houses and buildings, body bodies such as cars and trucks, and equipment such as ducts and piping, materials formed by firing glass wool, which is a very thin fiber, are used for the purpose of insulation and insulation. .

Glass wool is extremely thin and easily scattered around during processing. Therefore, in the manufacturing process of the sound absorbing heat insulating material, glass wool is mixed with an anti-scattering agent, and then a binder is added and then fired and molded. As the anti-scattering agent used herein, since it is easy to handle and excellent in permeability to glass wool, conventionally, surfactants such as petroleum sulfonate and polyoxyethylene alkylphenyl ether have been added to the oil component as it is or as it is. It is generally used to add water to make an emulsion.

However, if the sound-absorbing insulating material installed inside the wall of the building or inside the body of the body absorbs moisture, it is important that the sound-absorbing insulating material does not absorb moisture because it causes mold or rust.

Glass wool is inherently non-hygroscopic, but the conventional anti-scattering agent mixed therewith contains a hygroscopic surfactant, which is completely decomposed even at a firing temperature of 170 to 250 ° C. at the time of manufacturing the sound-absorbing insulation. It is customary to remain in the sound absorbing insulation afterwards. Therefore, in the case of using a conventional anti-scattering agent, it is necessary to apply or impregnate a water repellent such as wax, silicone oil, tetrafluoroethylene oligomer, etc. to the sound absorbing insulation material after firing and molding.

The inventors of the present invention overcame the above problems of conventional anti-scattering agents, and have been researched to develop a glass wool antiscattering agent that does not require the use of a water repellent. The wool shatterproof agent is found to be capable of imparting high water repellency to the glass wool molded material obtained even when it is fired at a low temperature of about 170 ° C by using it or adding water to make an emulsion. It came to the following.

An object of the present invention is to provide a glass wool shatterproof agent that can impart high water repellency to a glass wool molded material alone, and thus does not require the application of a water repellent to the molded material after firing and molding.

The glass wool scattering agent of the present invention is a mineral oil having a kinematic viscosity at 40 ° C. of 5 to 1000 mm 2 / s and / or a synthetic oil as a base oil, and a fatty acid having 6 to 24 carbon atoms and 1 to 3 molecules thereof. A salt of a C1-C44 amine having two nitrogen atoms is prepared by compounding 0.2 to 30% by weight based on the total amount of the composition.

The kind of mineral oil and / or synthetic oil is not specified, and it can be used irrespective of mineral oil type and synthetic type as long as it is normally used as a base oil of a solvent and lubricating oil.

As mineral oil base oil, for example, refining treatment such as solvent extraction, solvent extraction, hydrocracking, solvent fugitive removal, catalytic fugitive dehydrogenation, hydrorefining, sulfuric acid washing, and clay treatment may be carried out. Paraffin-based, naphthenic-based or aromatic-based residual components purified by appropriate combination can be used.

Salts obtained are salts obtained by reacting 1 to 3 moles of fatty acid with 1 mole of triamine having three nitrogen atoms in one molecule.

Although the shatterproof agent of the present invention is generally prepared by combining such a salt with a base oil, the scattering inhibitor of the present invention can be prepared even when a salt is formed in the base oil by separately combining a fatty acid and an amine.

The compounding quantity of a salt is 0.2-30 weight% on the basis of the total amount of a base oil and salt, Preferably it exists in the range of 1-10 weight%. If the blending amount is lower than this range, when water is added to the scattering agent to form an emulsion, the emulsion may have a lack of stability. Conversely, if the blending amount exceeds this range, the water-repellent imparting ability of the scattering agent decreases. Because, in each case it is not good at all.

To the scattering agent of the present invention, one or two or more well-known additives such as an antifoaming agent, a corrosion inhibitor, an anti-corruption agent, an antioxidant, and the like can be added, if necessary. The inhibitor usually contains about 0.001 to 2% by weight of each additive.

Although the glass wool scattering inhibitor which concerns on this invention can mix this with glass wool, it is preferable to disperse | distribute this to water and to use it in the form of an aqueous emulsion. When it is made of an aqueous emulsion, the mixing ratio of the anti-scattering agent and water can be arbitrarily selected, but is usually in the range of 50 to 5000 parts by weight of water, preferably 100 to 2000 parts by weight, relative to 100 parts by weight of the antiscattering agent.

In addition, instead of the salts of the fatty acids and amines of the present invention for comparison, an anti-scattering agent was used by using an anionic surfactant (Comparative Example 1), a non-ionic surfactant (Comparative Example 2) and a metal soap (Comparative Example 3), respectively. The water repellency evaluation test was carried out in the same manner using the preparations. The result was written together in Table 1. Furthermore, Comparative Example 4 is an example of impregnating wax after drying the glass wool treated with the agent of Comparative Example 1.

(Water repellency test)

An uncured glass wool having a bulk density of 16 kg / m 2 (shape: width 20 m × length 50 mm × thickness 50 mm) was placed in a glass bottle with a stopper, and contained 10% by weight of the anti-scattering agent shown in Table 1. 100 ml of an aqueous emulsion was added, the cap was sealed, shaken well, the mixture was well colored with an aqueous emulsion, and the glass was dried at 170 ° C. for 90 minutes. After that, 1 ml of distilled water was dropped onto the dried glass wool surface with a dropper, and the time until the water droplets formed on the glass wool surface were completely absorbed into the glass wool was measured, and this was used as a determination of water repellency ability. The longer this time, the better the scattering agent is in terms of water repellency.
