Embodiment 1

[0029] A method for manufacturing melamine-impregnated paper A method for manufacturing surface-layer melamine-impregnated wear-resistant paper, comprising the following steps: Step 1, preparing a bacterial cellulose film, using Acetobacter xylinum or Acetobacter pasteurianus as raw material, and using 55-70wt% sucrose and 30-45wt% fructose as carbon source, casein hydrolyzate as nitrogen source, fermented in a reactor with agitator to prepare bacterial cellulose wet film, then the bacterial cellulose wet film is taken out from the reactor Soak in NaOH solution with a concentration of 0.15mol / L, and then soak and rinse with deionized water several times to make the pH value reach neutral for later use or storage.

[0030] Step 2. Preparation of high-strength impregnated base paper

[0031] Cut the neutral bacterial cellulose wet film prepared in step 1 into small pieces with a size specification of 5-8mm×5-8mm, mix it with water at a weight ratio of 1:7, and spin it in a stand...

Embodiment 2

[0039] The manufacturing method of melamine decorative impregnated paper, compared with embodiment one, is different: step 4 is impregnated once and dried twice: impregnated and softened melamine resin according to high-strength impregnated base paper, dried, impregnated and softened melamine resin, dried, Cooling, cutting and other processes for manufacturing.

Abstract

The invention belongs to the field of wood-based panel, and specifically relates to a manufacturing method of melamine impregnated paper. The manufacturing method comprises following steps: step 1, bacterial cellulose films are prepared; step 2, impregnated base paper with high strength is prepared; step 3, a softening melamine resin impregnation liquid is prepared; and step 4, the melamine impregnated paper is prepared, wherein the softening melamine resin impregnation liquid obtained via step 3 is delivered into an impregnator, surface impregnated wear-resistant paper or decorative impregnated paper is prepared via first impregnation, first drying, second impregnation, and second impregnation, and obtained products are stored in a special warehouse with constant temperature and humidity. The melamine impregnated paper is capable of satisfying using demands of laminate flooring; methyl aldehyde content and VOC content are reduced at the same time; indoor air pollution is improved; and the manufacturing method is of great significance on protection of human life and health.

Description

technical field [0001] The invention belongs to the field of wood-based panels and relates to a method for manufacturing melamine-impregnated paper. Background technique [0002] As people continue to pursue new heights of material civilization and spiritual civilization, melamine-impregnated paper-faced wood-based panels are popular among people because of their strong oil resistance, water resistance, and stain resistance. Laminate flooring, also known as impregnated paper laminated wood flooring, is a kind of wood flooring made of high-density fiberboard or particle board as the base material, covered with melamine impregnated paper on the surface, and coated with a balance layer on the back. Laminate flooring has the advantages of beautiful surface, good wear resistance, good dimensional stability, strong pollution resistance, good impact resistance, and convenient installation. It has been widely used in the field of decoration and is deeply loved by consumers. [0003...
