Abstract

The invention provides a high-stability high-toughness melamine resin modifier. The melamine resin modifier is prepared from the following components in percentage by mass: 30-50% of fatty acid amide, 20-40% of polyethyleneglycol, 10-20% of alkylphenol polyoxyethylene and 10-30% of water. The melamine resin modifier is prepared by the following steps: putting the components in a proper container, slowly heating to 50-80 DEG C, stirring uniformly until all the components are dissolved, and cooling to room temperature to obtain the melamine resin modifier. The melamine resin modifier can effectively prolong the polymerization time of the melamine formaldehyde resin, increase the storage cycle and improve the toughness of the resin.

Description

technical field [0001] The invention relates to a modifier of melamine resin and a preparation method thereof, which can be used for optimizing the use effect of melamine resin, especially for the preparation of melamine-impregnated paper. Background technique [0002] Melamine formaldehyde resin is a thermosetting resin that can form a water-resistant, heat-resistant, wear-resistant, pollution-resistant, and glossy resin protective film. It is widely used in the furniture industry and is mostly used in the preparation of melamine-impregnated paper. At present, the quality of domestic melamine-impregnated paper is uneven, mainly because the use level of melamine resin modifiers varies greatly, resulting in melamine-formaldehyde resin surface brittleness and poor storage stability after curing. Common modifiers include diethylene glycol, glucosamine, caprolactam, etc. With the development of society, the market demand for melamine-formaldehyde resin-impregnated paper is incr...
