Description

Binder composition

The present invention relates to a binder for binding a fibrous material used as a sound insulation or heat insulating material, and a sound insulation or heat insulating material produced using the binder.

Mineral wool is a concept encompassing rock wool and glass fibers, and includes fibers made by melting minerals. The mineral wool has excellent sound insulation and heat insulation effect, and is used for building materials. As a manufacturing method thereof, minerals (slag, sand, andesite, basalt, quartzite, etc.) are melted in a furnace and introduced into a fiberizing device such as spinning balls. In this case, the binder is injected together. Through this process, the mineral material becomes a fiber shape, which can be heat-pressed through a multi-stage roller to squeeze while curing the binder, and then cut to a certain size to produce soundproof or heat insulating material as a final product.

Such a binder composition should have the property that the binder should be reacted with each other (including a polymer reaction) and crosslinked with the surface of the fiber (reaction or adsorption, etc.). Conventionally, although resol resin and formaldehyde were used, carcinogens Due to the occurrence of a problem with, etc., a method of mixing a polycarboxylic acid having a plurality of carboxyl groups and a polyhydric alcohol (polyol) having a plurality of hydroxyl groups and adding other additives such as silane has been studied. . Thus, the composition is crosslinked with carboxylic acid and hydroxyl groups, the ester is formed, the continuous development of which carboxylic acid and hydroxyl groups to be combined has been carried out, especially due to environmental problems Studies using polyhydric alcohols (including sugars) of substances (starch such as corn and cassava) as hydroxyl groups have also been conducted.

Korean Unexamined Patent Publication No. 2010-0065273 discloses that a raw material derived from a natural substance is used as a binder component. However, the present invention has a problem that the mechanical properties such as strength can be lowered compared to the conventional phenol formaldehyde resin.
