DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a glass fiber binder, particularly a glass fiber binder prepared by adding iron or a colloid of an iron compound or a water-soluble iron compound to an aqueous binder, and The present invention relates to a glass fiber mat obtained by using this.

(Prior Art) Conventionally, a glass fiber mat or felt used as a heat insulating material or a sound absorbing material is heat treated after a thermosetting resin such as phenol resin or urea-modified phenol resin is attached to cotton-like glass fiber. It is manufactured by curing the resin.

The glass fiber mat produced in this way is a so-called product that has properties such as heat insulation, sound absorption, weather resistance, and water resistance, as well as excellent elasticity, good texture, and favorable color tone. Performance is also required, and these are influenced not only by the shape of the glass fiber but also by the adhesion state of the binder and the chemical composition of the binder.

(Problems to be Solved by the Invention) That is, when the binder adheres to the surface of the glass fiber, the glass fiber mat is inferior in elasticity and texture because a network structure is not formed, and is coated with a thermosetting resin. As a result, not only the glass fiber becomes hard and brittle and loses its elasticity, but also the fiber easily breaks, causing inconvenience in handling and deteriorating the working environment. In order to eliminate these disadvantages, it is necessary to attach the binder spherically at the intersection of the entanglement of the glass fibers.

The binder is generally attached to the glass fiber by spraying an aqueous solution of the binder on the glass fiber, but in particular, in order to attach the binder in a spherical shape at the intersection of the entanglement of the glass fibers, many conventional methods have been adopted in the spraying method. Has been done. That is, the size of the spray droplets, the spray position, the temperature of the spray atmosphere, and the like have been studied, and various unique technologies have been proposed as the spray method, such as the air spray method and the direct pressure spray method of the binder. However, none of them has merits and demerits and various restrictions, and none is practically satisfactory.

On the other hand, glass fiber mats for heat insulating materials often have a dull yellow appearance, which reduces the commercial value. As measures against this, methods such as adding urea to the phenol resin or increasing the amount of ammonium sulfate used as a curing accelerator have been adopted, but increasing the amount of urea reduces the water resistance of the glass fiber mat of the product. Cause
Increasing the amount of ammonium sulfate causes the product to have an odor similar to that of fish. On the other hand, reducing the amount of urea and ammonium sulfate makes it difficult to obtain a bright yellow color, raises the product cost, and causes insufficient curing. ing.

(Means for Solving the Problems) The present invention has been achieved as a result of intensive research to solve these problems, and an iron or iron compound is added to an aqueous binder containing a water-soluble phenol resin as a main component. The present invention relates to a glass fiber binder obtained by adding the colloid or water-soluble iron compound, and a glass fiber mat obtained therefrom.

According to the present invention, by the extremely easy method of adding a small amount of iron or an iron compound to the conventional binder composition, the above-mentioned restrictions on spraying are greatly alleviated, and the spherical adhesion of the binder is greater than that of direct pressure spraying. It was confirmed that even with the air atomization method, which is said to be difficult, the binder adheres to the intersections of the glass fibers in a spherical shape, and the resulting glass fiber mat or felt is an excellent product with a bright yellow color.

Although it is not always clear as to why the excellent effect of the present invention is provided, iron or an iron compound added to the aqueous binder forms a complex or complex with the phenol resin, and appears to be a macromolecule. It is thought that this is because the adhesion state to the glass fiber is changed or the iron ion in the binder facilitates the adhesion of the phenol resin to the glass fiber.

Hereinafter, the present invention will be described in more detail. The aqueous binder used in the present invention contains a water-soluble phenol resin as a main component, and particularly contains 50% or more of the aqueous phenol resin in the solid content. It is preferable to add urea and ammonium sulfate and, if necessary, further add a silicone coupling agent such as aminoalkylsilane or a silicone water repellent, which is generally used as a binder for glass fibers.

As the iron or iron compound, a colloidal or water-soluble compound is used so as not to precipitate or block the spray nozzle. That is, this has a particle size of 50
Examples include iron colloids having a size of μm or less, iron or iron compound colloids such as iron hydroxide colloid, inorganic compounds such as iron chloride, iron sulfate, and iron nitrate, and organic compounds such as iron acetate, iron oxalate, and iron gluconate. . If the addition amount of these irons or iron compounds is too small, it is difficult to obtain a sufficient effect, and if the addition amount is too large, the effect is not promoted further, and the glass fiber mat of the product becomes a slightly dull yellow color. The amount of iron or iron compound added to the aqueous binder is 10 as the weight of the iron content relative to the water-soluble phenolic resin.
It is preferably ˜500 ppm. These irons or iron compounds may be added either in the binder preparation step or in the step of spraying the binder.
