Abstract

The invention discloses a preparation method of an impregnated paper for a decorative surface on high-glossiness furniture, belonging to the field of a decorative paper. The method comprises steps of: preparing modified melamine formaldehyde resin stock solution; impregnating a printing roll paper by a modified melamine formaldehyde resin stock solution groove, adjusting a quantifying roller, and controlling the glue quantity at 60-150g/m<2>; leading the impregnated roll paper into a first suspending type oven to dry at the temperature of 100-150 DEG C, coating modified melamine formaldehyde resin mixed liquor on the surface of the roll paper, and controlling the glue coating quantity at 40-100g/<2> by an anilox roll; and leading the roller-coated roll paper into a second suspending type oven to dry at the temperature of 100-150 DEG C, controlling a roll paper running speed at 10-12m/minutes, and cooling by a cooling roller to obtain the impregnated paper. The preparation method is reasonable in the technology, simple in operation, reliable in the obtained impregnated paper quality and obvious in effect.

Description

Technical field [0001] The invention relates to the field of decorative paper, in particular to a method for preparing high-gloss furniture facing impregnated paper. Background technique [0002] The pattern clarity, paint film fullness, gloss, transparency, scratch resistance, etc. of the surface of the panel furniture are reflected by the impregnated paper pressed on the surface of the substrate, and the gloss is an important indicator that determines the grade of the furniture. Therefore, improving the glossiness of the finish is the direction of the industry's efforts. [0003] At present, there are two main ways to improve the glossiness of furniture finishes. One is to process the surface of ordinary decorative paper by spraying, roller coating, brushing, grinding and polishing. Ester coating makes furniture finishes show a higher gloss; the other is to add a variety of different types of brighteners to produce impregnated paper, and then press the impregnated paper to the f...
