Abstract

The invention provides a production method of low-formaldehyde-releasing impregnating resin film paper. The production method comprises the following steps: uncoiling raw paper and pre-treating; impregnating the raw paper into a urea formaldehyde resin impregnating solution; conveying the impregnated raw paper into a drying oven; drying at the temperature of 120 DEG C to 140 DEG C for 25s to 35s; cooling the resin film paper which is dried for the first time, coating double faces of the paper with an amine-aldehyde resin solution; conveying the coated resin film paper into the drying oven again, and drying at the temperature of 130 DEG C to 155 DEG C for 35s to 45s; after drying for the second time and cooling, conveying the resin film paper into a cutting machine, and cutting the resin film paper into needed length. According to the low-formaldehyde-releasing impregnating resin film paper provided by the invention, formaldehyde release can be effectively reduced, and the formaldehyde releasing amount is not increased after high-temperature and high-pressure attachment; the quality and applicability of the impregnating resin film paper can be improved.

Description

technical field

[0001] The invention relates to the technical field of production of impregnated adhesive film paper, in particular to a production method of impregnated adhesive film paper with low formaldehyde emission. Background technique

[0002] With the improvement of people's living standards and the continuous enhancement of environmental protection awareness, the requirements for furniture are getting higher and higher, and the quality control of furniture in international trade is becoming more and more strict.

[0003] In recent years, the demand for low-carbon and environmentally friendly furniture has grown rapidly, but currently there is an extreme shortage of high-grade decorative materials suitable for low-carbon and environmentally friendly materials in the domestic market. Formaldehyde-free substrates for making decorative wood-based panels have come out, but there is no matching material for them. Impregnated laminated paper with low formaldehyde emission...
