本発明は、無機質繊維用とくに不燃性に優れた、ガラス
短繊維用のバインダーに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a binder for inorganic fibers, particularly for short glass fibers, which has excellent nonflammability.
ガラス繊維等の無機質繊維断熱材は、その優れた吸音性

広く使用されている。無機質繊維例えばガラス繊維を用
いて断熱材を製造するにあたっては、ガラスを繊維化し
た直後に、未硬化のバインダーを噴霧したマットを加熱
炉内を通過させつつ硬化させることにより製造される。Inorganic fiber insulation materials such as glass fibers are widely used as constituent materials for various buildings and vehicles due to their excellent sound absorption and heat insulation properties. When producing a heat insulating material using inorganic fibers such as glass fibers, immediately after the glass is made into fibers, a mat sprayed with an uncured binder is passed through a heating furnace and cured.
従来から用いられてきた一般的なバインダーとしては、

Aqueous binders made by adding or reacting urea to resol type phenolic resins are widely used. The use of urea in binders for inorganic fiber insulation is known in the art and is widely used as commercially acceptable.

量剤としての効用もある。The reason is that urea acts as a filler and easily reacts with free formaldehyde in resol type phenolic resin under weak alkaline or neutral pH conditions to form methylol urea, which is used in the inorganic fiber insulation manufacturing process. This is because it easily polymerizes to form a urea-formaldehyde resin binder at the curing temperature, and the role of urea is to reduce the free formaldehyde content in the resol-type phenolic resin, thereby reducing formaldehyde release from the resol-type phenolic resin. and also greatly reduce the emission of other volatile components. This reduction in volatile components increases the amount of binder deposited on the glass fibers at high temperatures during use and during the curing process, improving binder efficiency. Furthermore, since urea is currently approximately one-fifth the price of resol-type phenolic resins, it also has utility as an economical filler.

あった。When an inorganic fiber insulation material is created using the above binder, the nonflammability of the insulation material manufactured from this material decreases as the amount of binder attached increases and becomes a high-density, high-strength product, although the inorganic fiber itself is nonflammable. It's coming. That is, although the base material test of the noncombustible material test according to Ministry of Construction Notification No. 1828 passes, it approaches the criterion value. That is, in the base material test, when the heating furnace temperature was 750±IG°C and the temperature rise in the furnace after inserting the test specimen was below the criterion value of 50°C, it was 44 to 49°C, approaching the criterion. Therefore, there is only a margin of 5° C. with respect to the criterion value. Therefore, in order to improve the nonflammability, we increased the ratio of urea, which has higher flame retardancy than phenol resin and contains nitrogen in its molecular structure, and has traditionally been used for its mitigation effect. Although it improved, the ratio of urea resin contained in the cured binder increased, resulting in a defect that deteriorated water resistance.
従って、本発明はかかる欠陥のない、すなわち不燃性に
優れ且つ耐水性も良好なガラス繊維用バインダーを提供
しようとするものである。Therefore, the present invention aims to provide a binder for glass fibers that is free from such defects, that is, has excellent nonflammability and water resistance.

Now you can. The binder in which urea is added to or reacted with a resol-type phenolic resin, which has been used in the past, has a higher flame retardant property. In addition to providing flammability, the combined use of guanidine salts that can be copolymerized with urea or urea resins made it possible to improve the moisture resistance and water resistance defects of urea/formaldehyde resins.

たバインダーである。As detailed above, the nonflammable inorganic fiber insulation material made using the binder of the present invention can improve the grade of noncombustibility in addition to superior sound absorption and heat insulation properties compared to conventional ones. Conventional and commonly used inorganic fiber insulation materials that have a resol-type phenolic resin or urea-modified phenolic resin as the main component and use a binder to which urea has been added or reacted have only a margin of 5°C relative to the criteria. However, the inorganic fiber insulation material made using the binder of the present invention has a temperature margin of 10 to 30°C, making it possible to produce a high-quality, nonflammable inorganic fiber insulation material. Furthermore, this binder is an excellent binder that can be applied to all binders conventionally used for glass insulation materials.
