Description
技术领域
本发明涉及无醛强化木地板制作技术领域，具体为一种无醛强化木地板的制作方法。
背景技术
目前复合地板使用的胶粘剂仍以脲醛树脂为主，地板中残留未参与反应的甲醛会以气态形式向周围环境逐渐释放，甲醛是一种无色且具有强烈气味的刺激性气体，其水溶液称为福尔马林，可使蛋白质变性，医学中常用作防腐剂，当人们处于甲醛浓度较高的环境中，眼睛、鼻腔以及呼吸道就会发生不适的症状，往往会危害身体的健康，目前我们家庭和公共场所铺装的强化地板，没有其它有害的东西，就是一个游离甲醛释放的问题，在强化地板技术扩张、中国日益成为强化地板出口大国的发展当中，如果人长期处于甲醛超标的环境，对人体健康会造成一定的影响和伤害，甲醛对人体健康的影响主要包括嗅沉异常、刺激、过敏、肺功能异常、肝功能异常、免疫功能异常、中枢神经系统受影响、还可损伤细胞内的遗传物质，是可疑致癌物，为此，我们提出一种无醛强化木地板的制作方法。
发明内容
本发明的目的在于提供一种无醛强化木地板的制作方法，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种无醛强化木地板，木地板包括基板，基板的顶部和底部上均固定粘结装配有木炭复合热压板，且木炭复合热压板的外侧壁上热压成型有木纹纸，并在木纹纸的外侧壁上依次喷涂有底漆和面漆。
强化木地板制作方法的具体步骤为：
S1：基材选择：选择胶合强度、吸水膨胀率、静曲强度以及密度等各项指标符合或优于国标的中密度纤维板，其中厚度按所需要求选择，同时要选择甲醛释放量≤1.5mg/L且(穿孔萃取法)≤9mg/100g的基材，同时要对基材进行干燥处理；
S2：木炭复合热压板制备：
（1）选取50-60份竹炭粉、20-30份的树脂粉、2-4份的稳定剂、0.2-1份的PE蜡、1-2份的润滑脂、2-5份的发泡调节剂和1-4份发泡剂混合，一起倒入到搅拌机中进行高速搅拌混合均匀，能够制得干燥材料并冷却；
（2）冷却之后的干燥材料导入到挤出机中并挤出，挤出后对其用水进行冷却；
（3）将挤出后的板材进行牵引并进行裁切，能够制得半成品，然后将半成品的表面进行打磨，保证板材的表面显露出毛孔；
S3：甲醛清除液制备：选取材料：草酸、茶多酚、渗透剂和生物酶，按照重量份比为：30-50%的草酸、30-40%的茶多酚、10-20%的渗透剂和10-20%的生物酶，按照份量比选取原料并进行混合，混合时间为1-2小时，然后对其进行冷却；
S4：甲醛清除液用高压离子喷雾剂均匀喷涂在基材和木炭复合热压板的正反两面上，晾干后放在恒温烘干窑中进行热处理，并实时检测含水率和甲醛释放量，烘干时间以含水率和甲醛释放量均达到求为准；
S5：然后将基材的外侧壁上作涂胶处理，并将木炭复合热压板粘结装配在基材上，并在木炭复合热压板的表面上涂胶，然后通过热压处理贴上木纹纸并进行冷却；
S6：在木纹纸外壁上先后涂底漆和面漆，进行烘烤后即可制得无醛强化木地板。
优选的，S4步骤中用高压离子喷雾剂反复均匀喷涂在基材和木炭复合热压板的正反两面上，喷涂层数为三层，且恒温烘干窑中的温度维持在60-75度，烘干时间一般0.5-1.5小时，出窑温度一般55-65度。
优选的，S5步骤中热压处理条件为：热压压力为60-100N/cm2，热压温度为100-130度，热压时间为45-60秒。
优选的，S6步骤中底漆涂四遍，且面漆涂三遍，烘烤温度维持在100-120度。
与现有技术相比，本发明的有益效果是：
本发明选取胶合强度、吸水膨胀率、静曲强度以及密度等各项指标符合或优于国标的中密度纤维板，保证底板基材的环保性，同时基材外侧壁上的木炭复合热压板原料包含竹炭粉和树脂粉，通过树脂和竹炭粉的配合使得木炭复合热压板硬度大大提高，能抵抗大于普通碳板以上的承受压力，同时稳定剂改善了树脂粉混合分散不均的问题，提供了无尘生产产品的可能性，配合润滑脂的使用减小了加工摩擦，改能够善加工性能，提高材料分子之间的粘结性，进而改善板材的表面性能，CPE配合润滑脂的使用可有效提高板材的承载弹性，缓冲性较强，发泡剂可使其内部形成多个气孔，配合竹炭粉的使用不仅减轻板材的重量，而且竹炭粉还大大提升了板材对于甲醛的吸附效果，保证无不良有害物质，在木炭复合热压板制作完成后在其表面打磨出毛孔，这样在通过甲醛清除液对木炭复合热压板进行清理，使得板材对硫化物、氮化物、甲醛、苯、酚等有害物质具有良好的吸收和降解作用，得到的木地板不含甲醛，安全环保，将木炭复合热压板通过无醛胶压合装配在基材上，然后在木炭复合热压板的外壁上先后喷涂底漆和面漆并烘烤干，制得木地板力学性能好，不易变形，表面坚硬耐磨，防水性好，使用寿命长。
具体实施方式
下面将结合本发明实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例
一种无醛强化木地板，木地板包括基板，基板的顶部和底部上均固定粘结装配有木炭复合热压板，且木炭复合热压板的外侧壁上热压成型有木纹纸，并在木纹纸的外侧壁上依次喷涂有底漆和面漆；
强化木地板制作方法的具体步骤为：
S1：基材选择：选择胶合强度、吸水膨胀率、静曲强度以及密度等各项指标符合或优于国标的中密度纤维板，其中厚度按所需要求选择，同时要选择甲醛释放量≤1.5mg/L且(穿孔萃取法)≤9mg/100g的基材，同时要对基材进行干燥处理；
S2：木炭复合热压板制备：
（1）选取50-60份竹炭粉、20-30份的树脂粉、2-4份的稳定剂、0.2-1份的PE蜡、1-2份的润滑脂、2-5份的发泡调节剂和1-4份发泡剂混合，一起倒入到搅拌机中进行高速搅拌混合均匀，能够制得干燥材料并冷却；
（2）冷却之后的干燥材料导入到挤出机中并挤出，挤出后对其用水进行冷却；
（3）将挤出后的板材进行牵引并进行裁切，能够制得半成品，然后将半成品的表面进行打磨，保证板材的表面显露出毛孔；
S3：甲醛清除液制备：选取材料：草酸、茶多酚、渗透剂和生物酶，按照重量份比为：30-50%的草酸、30-40%的茶多酚、10-20%的渗透剂和10-20%的生物酶，按照份量比选取原料并进行混合，混合时间为1-2小时，然后对其进行冷却；
S4：甲醛清除液用高压离子喷雾剂均匀喷涂在基材和木炭复合热压板的正反两面上，晾干后放在恒温烘干窑中进行热处理，并实时检测含水率和甲醛释放量，烘干时间以含水率和甲醛释放量均达到求为准；
S5：然后将基材的外侧壁上作涂胶处理，并将木炭复合热压板粘结装配在基材上，并在木炭复合热压板的表面上涂胶，然后通过热压处理贴上木纹纸并进行冷却；
S6：在木纹纸外壁上先后涂底漆和面漆，进行烘烤后即可制得无醛强化木地板；
S4步骤中用高压离子喷雾剂反复均匀喷涂在基材和木炭复合热压板的正反两面上，喷涂层数为三层，且恒温烘干窑中的温度维持在60-75度，烘干时间一般0.5-1.5小时，出窑温度一般55-65度；
S5步骤中热压处理条件为：热压压力为60-100N/cm2，热压温度为100-130度，热压时间为45-60秒；
S6步骤中底漆涂四遍，且面漆涂三遍，烘烤温度维持在100-120度。
本发明选取胶合强度、吸水膨胀率、静曲强度以及密度等各项指标符合或优于国标的中密度纤维板，保证底板基材的环保性，同时基材外侧壁上的木炭复合热压板原料包含竹炭粉和树脂粉，通过树脂和竹炭粉的配合使得木炭复合热压板硬度大大提高，能抵抗大于普通碳板以上的承受压力，同时稳定剂改善了树脂粉混合分散不均的问题，提供了无尘生产产品的可能性，配合润滑脂的使用减小了加工摩擦，改能够善加工性能，提高材料分子之间的粘结性，进而改善板材的表面性能，CPE配合润滑脂的使用可有效提高板材的承载弹性，缓冲性较强，发泡剂可使其内部形成多个气孔，配合竹炭粉的使用不仅减轻板材的重量，而且竹炭粉还大大提升了板材对于甲醛的吸附效果，保证无不良有害物质，在木炭复合热压板制作完成后在其表面打磨出毛孔，这样在通过甲醛清除液对木炭复合热压板进行清理，使得板材对硫化物、氮化物、甲醛、苯、酚等有害物质具有良好的吸收和降解作用，得到的木地板不含甲醛，安全环保，将木炭复合热压板通过无醛胶压合装配在基材上，然后在木炭复合热压板的外壁上先后喷涂底漆和面漆并烘烤干，制得木地板力学性能好，不易变形，表面坚硬耐磨，防水性好，使用寿命长。
