Embodiment

[0042] Embodiment: a kind of manufacture method of impregnated adhesive film paper for low-formaldehyde furniture, comprises the following steps:

[0043] 1) Selection and processing of base paper: choose ordinary base paper or printing paper;

[0044]2) Uncoiling: pre-treat ordinary base paper or printing paper by smoothing and deburring; the printing paper or ordinary paper is transported from the base paper warehouse and put into a dual-axis uncoiler with a damping device that can provide the required tension for the paper. Here In the uncoiler, after a roll of paper is used up, the new paper roll can be glued to the end of the previous roll of paper without stopping the production line to realize continuous work; the deburring pretreatment refers to the process of unwinding. First use a deburring device to deburr its surface, set a support 1 above the biaxial uncoiler, set a sliding fine brush 3 for deburring on the support 1, and the upper end of the fine brush 3 is place...

Abstract

The invention discloses a manufacturing method of impregnated bond paper for low formaldehyde furniture. The method comprises the steps of raw paper selection and treatment, uncoiling, pre-wetting, impregnation, first time drying, gluing, preparation of coating glue, second time drying, deviation adjustment traction and cutting. The manufacturing method has the advantages that the quality of the impregnated bond paper prepared with the method is high, the content of formaldehyde is further reduced, the uniformity of impregnation and gluing of the impregnated bond paper is guaranteed in the manufacturing process, the flexibility of a glue layer and the sealing performance of the surface of the glue layer are guaranteed, and accordingly, the problems that the content of formaldehyde is high and the quality is not high in impregnated bond paper are fundamentally solved.

Description

technical field [0001] The invention relates to a method for manufacturing low-formaldehyde furniture impregnated film paper. Background technique [0002] The existing standard "GB / T 28995-2012 Decorative Paper" divides the formaldehyde emission of impregnated paper into A and B grades, A grade requires ≤1.5, B grade requires ≤3, and now impregnated paper is generally produced according to B grade, formaldehyde The emission index is generally about 2.5. Although the formaldehyde emission of the sheet can reach E1 after the impregnated paper veneer, it is too far from the E0 (or no formaldehyde) required by the mainstream downstream furniture factories. The uniformity of impregnation and gluing in the process of film paper is poor, and the drying effect is poor, which makes the low-molecular substances dissipate slowly, and the sealability and flexibility of the impregnated film paper produced by the traditional process are relatively low. Poor, poor environmental performan...
