Problems solved by technology

[0002] Wood-based panel surface veneer is currently the trend of the entire decorative material market, but the problem caused by the release of formaldehyde in melamine-impregnated paper has long plagued the veneer of decorative materials, and the inability of impregnated paper to curl virtually limits its application range. Increased shipping and storage costs
Painted paper has developed rapidly in this situation. Painted paper is divided into pre-impregnated painted paper and post-impregnated painted paper. Although pre-impregnated painted paper and post-impregnated painted paper can be curled, the processing technology of pre-impregnated painted paper needs to be printed. , Coating, post-impregnation paint paper needs printing, dipping, coating, post-impregnation paint paper has complex process requirements, high cost, and low output
Conventional paint paper on the market is solvent-based coating, and the conventional solvent content in the coating oil is 40%-60%, and a large amount of organic and volatile organic solvents are released into the air, causing environmental pollution
With conventional water-based coating oil coating, the surface tension of the printing ink is obviously greater than that of the water-based coating oil, resulting in the inability of the water-based coating oil to spread, shrinkage cavities, poor adhesion, low surface clarity and poor flatness And other issues

Embodiment 1

[0022] The production technology of the water-based coated paint paper of the present embodiment comprises the following steps:

[0023] Step 1: Set the feed speed of the pre-impregnated paper to 50m / min, print the environmental ink on the surface of the pre-impregnated paper through the printing unit of the printing machine to form patterns and patterns, and enter the oven at 110°C for drying to obtain printed Paper;

[0024] Step 2: Pass the printing paper obtained in Step 1 through the surface treatment unit of the printing machine, apply the ink binder of ethers on the surface of the ink to reduce its surface tension, and dry it in a large oven at 125°C to obtain Printing paper for the surface treatment layer; the ink binder of ethers is composed of ethylene glycol butyl ether, amino resin and ethyl acetate in a mass ratio of 1:1.0:8.

[0025] Step 3: Pass the printing paper processed in step 2 through the paint layer roller between the water-based paint layer roller and ...

Embodiment 2

[0028] The production technology of the water-based coated paint paper of the present embodiment comprises the following steps:

[0030] Step 2: Pass the printing paper obtained in Step 1 through the surface treatment unit of the printing machine, apply the ink binder of ethers on the surface of the ink to reduce its surface tension, and dry it in a large oven at 130°C to obtain Printing paper for the surface treatment layer; the ink binder of ethers is composed of ethylene glycol butyl ether, amino resin and ethyl acetate in a mass ratio of 2:2.5:9.

[0031] Step 3: Pass the printing paper processed in step 2 through the paint layer roller between the water-based paint layer roller and ...

Embodiment 3

[0034] The production technology of the water-based coated paint paper of the present embodiment comprises the following steps:

[0035] Step 1: Set the feed speed of the pre-impregnated paper to 80m / min, print the environmental ink on the surface of the pre-impregnated paper through the printing unit of the printing machine to form patterns and patterns, and enter the oven at 140°C for drying to obtain printed Paper;

[0036] Step 2: Pass the printing paper obtained in Step 1 through the surface treatment unit of the printing machine, apply the ink binder of ethers on the surface of the ink to reduce its surface tension, and dry it in a large oven at 135°C to obtain Printing paper for the surface treatment layer; the ink binder of ethers is composed of ethylene glycol butyl ether, amino resin and ethyl acetate in a mass ratio of 3:3.5:12.

[0037] Step 3: Pass the printing paper processed in step 2 through the paint layer roller between the water-based paint layer roller and...

Abstract

The invention provides water-based coating vanished paper. The water-based coating vanished paper is of a laminated structure, and includes pre-impregnated paper, an ink printing layer, an ink surfacetension treatment layer, a base print layer and a finish paint layer separately from top to bottom. The production process includes the steps that pre-impregnated base paper is directly printed withink by a printing machine regardless of the thickness, the ink is transferred onto the surface of the pre-impregnated paper through a plate roller of the ink, and the pre-impregnated paper is treatedwith an ether surface treatment layer after printing to reduce the surface tension, so that water-based paint is easily spread and is easy to use for coating, and the phenomena of hole shrinkage and surface blemishing do not occur. Compared with vanished paper produced by means of a post-impregnation production process, the water-based vanished paper produced by means of a production process abovehas the advantages that the production process is simple, the gram weight of the base paper for production use can be different, the consumption amount of the primer and the finish paint for production is little, the cost is saved, the production efficiency is significantly higher than that of the post-impregnation vanished paper, the process is simple and suitable for industrial production, andthe production efficiency is improved.
