Description

一种快速导热的地热地板及生产工艺 技术领域
本发明涉及一种地热地板，特别是一种快速导热的地热地板及生产工艺。
背景技术
地热地板是通过地板辐射采暖，室内温度均匀，温度从地面向上辐射，由下而上递减。由于地热地板要承受30至50摄氏度的温差，对地热地板的耐热能力、收缩性能、木材密度等技术指标都具有比普通地板高得多的标准。地热地板包括纯实木地热地板和碳化实木地热地板。纯实木地热地板是指不改变实木地板自然属性的基础上能直接用于地采暖(地热)环境的实木地板；碳化实木地热地板用高温炭化对木材坯料进行几百度的高温处理，破坏了木材的原有结构，铺装后舒适感自然变差。但是，由于应用于地热的纯实木地板和碳化实木地板的厚度均较厚，导致其热传导速度较慢，从而使得地热地板整体的导热效果较差。另外，由于地热地板需要承受30-50℃的温差，使用一段时间后，现有的地热地板也会比较容易发生变形现象。因此，现有的技术存在着导热速度慢的问题。
发明内容
本发明的目的在于，提供一种快速导热的地热地板及生产工艺。 本发明具有导热速度快的特点。
本发明的技术方案：一种快速导热的地热地板，包括木皮，木皮下表面并排设有一组板条，相邻板条之间设有导热槽；所述板条一端设有榫头，板条另一端设有榫槽。
前述的一种快速导热的地热地板中，导热槽的宽度为1.5-2mm。
前述的一种快速导热的地热地板中，所述板条的厚度为4-20mm，板条的宽度为32-35mm。
前述的一种快速导热的地热地板中，所述木皮的厚度为2-6mm。
一种快速导热的地热地板的生产工艺，包括以下步骤：
第一步、选用SF级针叶型板材作为基材；
第二步、对基材进行分片，得到板条，每片板条的厚度为4-20mm，所述板条的宽度为32-35mm；
第三步、将多片板条按顺序放置于模具中进行串联，得到A品；相邻板条之间的间距为1.5-2mm；确保板条的平整度和相邻板条排布的精度；
第四步、将木皮和A品放入平衡窑内作平衡处理，控制平衡窑内的温度为40-50℃，分别得到干燥木皮以及具有干燥板条的B品；所述干燥木皮和B品中的干燥板条的含水率均为5-7％；从而可以保证木皮和板条在地热的使用环境下的稳定性，既不会变形也不会开裂；
第五步、在干燥木皮的背面涂覆胶粘剂，将B品放置在木皮的涂胶面并对B品进行压紧，压紧完成后取出B品中的模具，得到坯板；采用70-75℃的温度、8-10MPa的压力对B品进行压紧作业，压紧的 时间为6-10min；采用低温压紧工艺，相对冷压而言，能够大幅提高效率(冷压需60分钟完成，而低温压紧只需6-10分钟就能够完成同等的压紧效果，效率大幅度提升)，相对热压而言，低温压紧能够有效控制地板变形，避免木皮开裂；
第六步、分别在坯板上每片干燥板条的两端开设榫槽和榫头，得到成品。
前述的一种快速导热的地热地板的生产工艺中，所述木皮选用阔叶型木皮，木皮的厚度为2-6mm。
前述的一种快速导热的地热地板的生产工艺中，所述基材为径切板材。
前述的一种快速导热的地热地板的生产工艺中，所述胶粘剂中的固含量为55％。
前述的一种快速导热的地热地板的生产工艺中，所述的榫槽或榫头的开设过程为：用锯刀对预开设榫槽或榫头的区域进行走刀处理，完成预切割，然后在进行相应的开槽处理。能够避免板条劈裂、掉皮，保证槽口光滑和美观。
与现有技术相比，本发明由木皮和一组设置在木皮下方呈间隔分布的板条组成，相邻的板条之间形成有间距为1.5-2mm的导热槽，对板条的宽度作了合理优化限定，通过上述的相互配合，既保证了板条与木皮之间的接触面积，也为地板弯曲提供了充足空间，从而在能够保证地板整体强度的前提下还可以提高地板整体的韧性；通过设置导热槽，使得部分区域经空气直接传热，减少热损，从而可以有效的提 高地热地板整体的导热效率，进而实现地热地板的快速传热，经测试，导热效率可以提高30％；本发明通过木皮和板条之间的特殊结构以及板条的厚度、宽度之间的相互配合，得到的地热地板既具有快速导热的优点，又具有良好的柔韧性；同时，由于地板具有良好的柔韧性，使得地板在安装时能够与地面良好的贴合，从而可以有效的降低地板安装的空鼓率，进而可以减少在地板上走动所产生的噪音，起到降噪的目的。另外，本发明以均匀间隔分布的板条来取代传统的整体式木板，既可以节省材料，又可以有效的提高地热地板整体的柔韧性，而且导热槽还可以缓解释放地板热胀所产生的应力，减少地板的变形，改善地热地板整体的稳定性能。而且，本发明采用在木皮下方设置间隔分布的板条的方式来组成地热地板，并通过合理优化板条的宽度和相邻板条间距，使其在使用一段时间后，木皮的上表面也不会凸显板条的印子。综上所述，本发明具有导热速度快的特点。
另外，本发明采用径切板材的板条，利用径向传热，从而可以进一步的提高地板整体的导热效果。
