Description
技术领域Technical Field
本发明涉及装饰纸技术领域，特别是涉及一种人造板饰面装饰纸及其制备方法和饰面人造板。The invention relates to the technical field of decorative paper, in particular to a decorative paper for artificial board facing, a preparation method thereof and a facing artificial board.
背景技术Background technique
目前，饰面人造板已经在室内装修、家具等领域得到了广泛的应用。装饰纸是一种重要的人造板饰面材料，对人造板品起着保护和美化作用。然而，现有的装饰纸的浸渍处理多采用脲醛树脂和三聚氰胺-甲醛树脂等醛类胶黏剂，赋予纸页较好的硬度、附着力、耐酸碱等性能，但上述胶黏剂会在装饰纸生产和产品使用过程中释放游离甲，甲醛受热易挥发，在热压过程中会对从业者身体健康造成伤害。目前，随着社会的进步和人们环保意识的提高，家居木制品的环保性能越来越受到人们的关注。装饰纸的环保性和无醛化，对人造板的环保性能和对人体的健康具有重要意义。因此，开发耐磨性、耐刮擦性和附着力好等物理性能好的无醛化饰面装饰纸成为家居木制品及相关行业亟待解决的问题。At present, veneered artificial boards have been widely used in the fields of interior decoration, furniture, etc. Decorative paper is an important veneer material for artificial boards, which plays a role in protecting and beautifying artificial board products. However, the existing decorative paper impregnation treatment mostly uses aldehyde adhesives such as urea-formaldehyde resin and melamine-formaldehyde resin to give the paper sheets good hardness, adhesion, acid and alkali resistance and other properties, but the above adhesives will release free formaldehyde during the production and use of decorative paper. Formaldehyde is easily volatile when heated, and will cause harm to the health of practitioners during the hot pressing process. At present, with the progress of society and the improvement of people's environmental awareness, the environmental performance of home wood products has attracted more and more attention. The environmental protection and formaldehyde-free nature of decorative paper are of great significance to the environmental performance of artificial boards and human health. Therefore, the development of formaldehyde-free veneer decorative paper with good physical properties such as wear resistance, scratch resistance and good adhesion has become a problem to be solved urgently in home wood products and related industries.
发明内容Summary of the invention

应用例1Application Example 1
取实施例1和对比例1-2的饰面装饰纸，在压力为4Mpa、温度为165℃条件下将浸渍胶膜纸单面热压于人造板上2min，人造板板体为纤维板，印刷原纸采用定量为70g/m2装饰纸制得饰面人造板，所述饰面人造板的密度为0.7-0.8g/cm3，实施例1和对比例1-2的饰面装饰纸的浸胶量为175±5g/m3。The facing decorative paper of Example 1 and Comparative Examples 1-2 was taken, and the impregnated adhesive film paper was hot pressed on one side of the artificial board for 2 minutes under the conditions of a pressure of 4 MPa and a temperature of 165° C. The artificial board body was a fiberboard, and the printing base paper was a decorative paper with a basis weight of 70 g/m 2 to prepare the facing artificial board. The density of the facing artificial board was 0.7-0.8 g/cm 3 , and the amount of adhesive impregnation of the facing decorative paper of Example 1 and Comparative Examples 1-2 was 175±5 g/m 3 .
按照GB/T 28995-2012测试人造板饰面装饰纸的甲醛释放量和纸张挂胶量并观测人造板饰面装饰纸的外观质量，可以看到实施例1和对比例1-2的人造板饰面装饰纸表面不存在破损、污斑、缺口等，产品外观质量均符合GB/T 28995-2012的标准，人造板饰面装饰纸甲醛释放量均为0mg/L。According to GB/T 28995-2012, the formaldehyde emission and the amount of glue hanging on the wood-based panel decorative paper were tested and the appearance quality of the wood-based panel decorative paper was observed. It can be seen that there is no damage, stains, or gaps on the surface of the wood-based panel decorative paper of Example 1 and Comparative Examples 1-2. The product appearance quality meets the standard of GB/T 28995-2012, and the formaldehyde emission of the wood-based panel decorative paper is 0 mg/L.
按照GB/T15102-2017分别测定饰面人造板的表面胶合强度、表面耐磨性、表面耐水蒸气性、表面耐划痕(≥1.5N表面无大于90％的划痕)、表面耐龟裂性和表面耐冷热循环性，测试结果如下表所示：According to GB/T15102-2017, the surface bonding strength, surface wear resistance, surface water vapor resistance, surface scratch resistance (≥1.5N surface without more than 90% scratches), surface crack resistance and surface resistance to cold and hot cycles of the veneer wood-based panels were tested respectively. The test results are shown in the following table:
由上表可知，本发明制得的人造板饰面装饰纸应用于饰面人造板，可使得饰面人造板具有优异的表面胶合强度、表面耐磨性、表面耐水蒸气性、表面耐划痕、表面耐龟裂性和表面耐冷热循环性等性能，使用寿命长，并可减少甲醛的释放，对环境友好，降低对人体的损害。It can be seen from the above table that the artificial board veneer decorative paper prepared by the present invention is applied to the veneer artificial board, which can make the veneer artificial board have excellent surface bonding strength, surface wear resistance, surface water vapor resistance, surface scratch resistance, surface crack resistance and surface resistance to cold and hot cycles, etc., and has a long service life. It can also reduce the release of formaldehyde, is friendly to the environment, and reduces damage to the human body.
