Description
技术领域
本发明属于复合板材制造技术领域,具体涉及一种单板饰面超强刨花板及其制造工艺。
背景技术
刨花板是人造板的主要品种之一,是将木材或非木材植物纤维原料加工成刨花(或碎料),施加胶粘剂(和其他添加剂),组胚成型并经热压而成的一类人造板,又称碎料板。目前主要用于家具制造、装饰装修和建筑工业等。刨花板具有表面平整,绝热、吸音隔音、耐污染、耐老化及价格便宜等优点。过去10年中国刨花板产量年均增速达到12.1%,带动了林产工业健康发展。
刨花板性能特点决定了其主要应用于家具制造、包装及建筑装修等领域,绝大部分为干燥状态下使用的普通型或家具型刨花板。而定向刨花板凭借其优越的机械力学性能广泛地用于墙板、地板、楼面板等领域。如何提高普通刨花板的机械力学性能,拓宽其在木地板、墙板及楼面板等非结构建筑领域应用,是本领域需攻关研究的技术问题。而采用薄木贴面的二次加工贴面法效果最为显著,方法是将薄木涂胶后与刨花板上下两面组坯,通过热压胶拼成一体的饰面刨花板。二次贴面不仅起到美观效果,还显著提高刨花板力学性能,对满足市场的差异化个性化需求、提高人造板产品附加值、推动人造板行业创新发展具有重要意义。
发明内容
针对上述存在的不足,本发明的目的在于针对刨花板性能缺陷及现有技术的不足,提供一种用实木单板胶合饰面得到的高强度复合单板饰面超强刨花板及其制造工艺,根据单板的纹理,通过控制多层单板的排版方式及设置防辐射金属网层,防电磁辐射的同时还能提高其机械力学性能,扩宽其在高档家具、地板、墙板及楼面板等领域应用范围,推动人造板特别是刨花板的转型升级发展。
为了实现上述目的,本发明采用的技术方案如下:
一种单板饰面超强刨花板,包括刨花板本体、胶黏剂层、面层,其特征在于:所述刨花板本体两侧面分别设有所述面层;所述面层与所述刨花板本体之间通过所述胶黏剂层胶合固定,所述面层包括相互贴合的防辐射金属网层和单板,所述防辐射金属网层的外侧设有至少一张所述单板。
具体的,所述防辐射金属网层的外侧面贴合有一张所述单板,所述防辐射金属网层的内侧面设有至少一张所述单板,其中最内层的所述单板与所述刨花板本体的侧面贴合。
具体的,所述单板为实木旋切单板,实木旋切单板的厚度为1.0-3.0mm。
具体的,所述刨花板厚度为5.0-40.0mm。
具体的,所述防辐射金属网层为钢丝网、铁丝纱网、铜丝布的任意一种。
具体的,所述单板饰面超强刨花板的静曲强度为24-35MPa,弹性模量为3300-4000MPa。
具体的,所述胶粘剂层由以下重量份的原料组成:木材胶粘剂70.0-80.0份、固化剂1.0-5.0份、填充剂10.0-30.0份。
具体的,所述木材胶粘剂为环保等级的三醛类树脂胶黏剂的一种或几种混合;所述的固化剂为氯化铵、硫酸铵、六甲基四胺中的一种或几种混合;所述填充剂为面粉、豆粉、豆粕粉、玉米粉、木薯粉的一种或几种混合。使得产品甲醛释放量低,有利于节能环保。
具体的,所述胶粘剂层施加量为50-150g/m2。
一种单板饰面超强刨花板的制造工艺,包括以下步骤:
1)将刨花板、面层的单板、防辐射金属网层分别涂上胶黏剂;
2)将涂有胶黏剂的其中一张单板贴合固定在防辐射金属网层的外侧面,然后在防辐射金属网层的内侧面按照单板木纹纹理进行互相垂直方式排列或平行方式排列贴合固定其余单板,得到面层坯;
3)将步骤2)得到的面层坯按照单板木纹纹理进行互相垂直方式或平行方式分别胶合固定在刨花板的两侧面,得到刨花板组坯;
4)将步骤3)组好的刨花板组坯送至压机压板台上,于100-150℃热压机上热压110-240s后卸压出板,并转移到指定位置堆垛,经室温放置养生即完成生产制造过程。
综上所述,本发明由于采用了上述方案,本发明具有以下优点:
1、本发明单板饰面超强刨花板,能显著提高产品力学强度,扩大其使用范围及使用寿命,增加了产品附加值,且制造工艺简单,工业生产效率高。
2、本发明创造性的采用多层单板,按其木纹纹理的不同,以垂直或平行的排板方式压贴在刨花板的两面,能显著提高其静曲强度和弹性模量等机械力学性能,经实验证明,静曲强度为24-35MPa,弹性模量为3300-4000MPa,力学强度提高了50%以上,使得产品兼具刨花板和胶合板的性能特点,不但降低了复合板材的厚度偏差,而且提高了复合板的静曲强度和尺寸稳定性,有利于二次饰面加工应用。
3、本发明能有效拓宽刨花板的使用范围,提高产品附加值,解决了难以实现工业化或自动化生产等共性技术瓶颈问题,同时还能节省30%以上的原料成本,具有显著社会效益和经济效益。
4、由于电磁波遇到金属等导电物质会被反射或吸收,本发明通过设置防辐射金属网层,使得刨花板兼具有电磁屏蔽功能,可以有效屏蔽或吸收掉电磁波,具有防辐射的功能。
5、本发明所用胶黏剂胶合强度高,固体含量高(固含量≥70%),流动性好,涂胶效果均匀,解决了因刨花板本体或单板含水量波动大易引起热压后刨花板分层、鼓泡等缺陷,同时热压固化速度快,具有生产效率高及成本低的优点。
6、本发明单板饰面超强刨花板甲醛释放量达到环保E0级(≤0.5mg/L),说明甲醛释放量极低,属于绿色环保产品。

通过上述刨花板的结构设计,所得单板饰面超强刨花板为高强度复合刨花板,防电磁辐射的同时还能提高了其机械力学性能,扩宽了其在高档家具、地板、墙板及楼面板等领域应用范围,使得产品兼具刨花板和胶合板的性能,推动了人造板特别是刨花板的转型升级发展。
本实施例中,作为优选的,单板5为桉木旋切单板,单板厚度为1.6mm;
刨花板1的厚度为12mm;
胶粘剂层2为木材胶粘剂75.0份、固化剂5.0份、面粉25份,各组分均匀混合后使用;
木材胶粘剂为环保脲醛树脂,所述固化剂为氯化铵、硫酸铵、六甲基四胺的一种或几种混合,所述填充剂为豆粉和豆粕粉按1:1的比例混合而成;
胶粘剂层2施加量为50-90g/m2。
一种单板饰面超强刨花板的制造工艺,包括以下步骤:
1)将刨花板、面层的单板、防辐射金属网层分别涂上胶黏剂;
2)将涂有胶黏剂的其中一张单板贴合固定在防辐射金属网层的外侧面,然后在防辐射金属网层的内侧面按照单板木纹纹理进行互相垂直方式排列或平行方式排列贴合固定其余单板,得到面层坯;
3)将步骤2)得到的面层坯按照单板木纹纹理进行互相垂直方式或平行方式分别胶合固定在刨花板的两侧面,得到刨花板组坯;
4)将步骤3)组好的刨花板组坯送至压机压板台上,于100-150℃热压机上热压110-240s后卸压出板,并转移到指定位置堆垛,经室温放置养生即完成生产制造过程。
为了研究刨花板基材经旋切单板饰面压贴后静曲强度及甲醛释放量的变化情况,使用经前期试验确定的3种胶进行饰面压贴,并按标准要求进行静曲强度及甲醛释放量测比较试验:
一、试验工艺参数
1、刨花板:12mm规格、18mm规格;
2、外购旋切单板(桉木):1.6mm;
3、调配胶:饰面胶+2.5%固化剂+25%面粉(混合搅拌均匀);
4、单板涂胶量:50-90g/m2;
5、热压工艺:时间为200-230s;压力=2.4~1.45MPa;温度=130~145℃;
6、实验日期:2017.10.16-2017.10.30。
二、试验结果
1、表1:12mm刨花板压贴单板后的力学性能试验结果
2、表2:18mm无醛刨花板压贴单板后的力学性能试验结果
3、表3:试样经平衡处理后用干燥法检测甲醛释放量结果
表1
表2
表3
三、试验结论
由表1、表2、表3可得出以下结论:
1、12mm刨花板经过单板压贴后的静曲强度(34.2MPa)比素板的静曲强度(14.5MPa)最高提高了约2.3倍;弹性模量(4007.8MPa)比素板的弹性模量(2447MPa)提高约1.6倍,说明本发明能显著提高其静曲强度和弹性模量等机械力学性能。
2、18mm刨花板经过压贴后的静曲强度(29.2MPa)比素板的静曲强度(18.3MPa)提高约1.59倍;弹性模量(3568.8MPa)比素板的弹性模量(2845MPa)提高约1.2倍,说明本发明能显著提高其静曲强度和弹性模量等机械力学性能。
3、本发明刨花板甲醛释放量达到环保E0级(≤0.5mg/L),说明甲醛释放量极低,属于绿色环保产品。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
