Embodiment 1
[0052] After preparing the material, calculate by weight: add 20% softwood pulp fiber, 20% hardwood pulp fiber, 10% polyester fiber (1.67D, 6mm), and control the online concentration at 0.38%-0.42%, quantitative 180g / m 2 .
[0053] Glue inside the machine 180g / m 2 . Coating liquid formula: 25 parts of acrylic latex (SJ-2), 25 parts of acrylic latex (R959), and the index of paper is as follows:
[0054] Quantitative 360g / m 2 , thickness 39S, longitudinal tensile strength 1.4KN / m, transverse tensile strength 0.7KN / m.
[0055]After pressing the board, the bonding force is good, there is no delamination phenomenon, and there is no wood silk grain contrasting to the decorative layer.
Embodiment 2
[0057] After preparing the material, calculate by weight ratio: add 15% softwood pulp fiber (25D 30mm), 20% hardwood pulp fiber, 15% polyester fiber (6D, 12mm) online concentration is controlled at 0.38%-0.42%, quantitative 200g / m 2 .
[0058] Glue inside the machine 190g / m 2 . Coating liquid formula: 25 parts of acrylic latex (SJ-2), 25 parts of acrylic latex (R959), and the index of paper is as follows:
[0059] Quantitative 390g / m 2 , thickness 39S, longitudinal tensile strength 1.6KN / m, transverse tensile strength 0.92KN / m.
[0060] After pressing the board, the bonding force is good, there is no delamination phenomenon, and there is no wood silk grain contrasting to the decorative layer.

Abstract
The invention provides ecological decorative paper and a production method thereof. The ecological decorative paper is prepared from the following raw materials in parts by weight: 15-20 parts of softwood pulp fiber, 15-20 parts of hardwood pulp fiber, 10-20 parts of polyester fiber, and 40-50 parts of modified thermoset resin. The ecological decorative paper is produced through steps of size degradation, beating, molding, drying, gluing, drying in a baking oven, sheeting and packaging by a fourdrinier machine. The product possesses the following advantages: 1, the product is good in eveness, stable in quality and stable in thickness, does not contain formaldehyde, melamine and other harmful substances, and is healthy and friendly to environment; 2, the product possesses good thermosetting performance, and therefore the product and a single plate and a decoration layer can be directly subjected to hot pressing for preparing a decoration sheet material, operations of sanding, glue preparation, glue blending, glue coating and the like of a single plate and a surface plate are saved, and production time, raw material cost and labor cost are saved. The product is a truly environment-friendly health product. The method of using the ecological paper for replacing the surface layer of a lumber core board is initially created in household sheet material industry, and the excellent performances of the product surly will bring revolutionary change for household sheet material industry.
Description
technical field [0001] The invention belongs to the field of home decoration woodworking boards, in particular to an ecological decorative paper and a production method thereof. Background technique [0002] High-grade blockboard is the main woodworking material used in the home decoration industry. The blockboard has a large format, is easy to saw, has strong material toughness, strong bearing capacity, and is not easy to crack. The board itself has moisture-proof performance and strong nail-holding force. It is convenient for comprehensive use and processing and other physical characteristics. [0003] 1. Woodworking board structure: The blockboards currently produced in my country are all 5-layer structures such as figure 1 shown; [0004] 2. Woodworking decorative board is a decorative layer on one or both sides of the woodworking board. This decorative layer can be: solid wood veneer, technical veneer or decorative film paper. The finished product is as follows: fig...
