Description

一种力学生态板及力学生态板制作方法
技术领域
本发明涉及材料制备领域，具体涉及一种力学生态板及力学生态板制作方法。
背景技术
在木材市场上，集成材、人造板品种繁多，质量参差不齐，如：三聚氰胺板、装饰板、多层板、细木工板等各式人造板，但是人造板中甲醛含量高，对人体有致命的致癌作用，非常不利于身体健康，因此越来越多的生态板应运而生，生态板中其甲醛的含量正常情况下甲醛的含量较低，避免了因甲醛含量过高对人体的损害，但是目前常规的生态板由于其自身特点，一来防虫、防潮以及防霉性能不佳；二来还存在着耐候性差、不抗撞击、不抗变形、握钉力差、阻燃性能差以及耐腐蚀性能差的缺点，从而导致其使用寿命短暂，既不环保又容易造成浪费。
发明内容
为解决上述问题，本发明提供了一种力学生态板及力学生态板制作方法，所得的生态板具有优良的力学性能、耐候性、耐阻燃性和耐腐蚀性。
为实现上述目的，本发明采取的技术方案为：
一种力学生态板的制作方法，包括如下步骤：
S1、按质量份称取三聚氰胺改性树脂100份、导热填料10-50份、红外反射二氧化钛0.5-5份、光稳定剂0.2-1.0份、耐化学品改性剂5-15份、2-咪唑烷酮12-28份、阻燃协效剂2-6份、溴系阻燃剂5-25份、抗氧剂0.1-1份；
S2、将称取的导热填料、光稳定剂、耐化学品改性剂、阻燃协效剂、溴系阻燃剂、抗氧剂通过超声波振荡设备分散于三聚氰胺改性树脂中，然后将木纹纸在其内依次进行第一次浸渍处理、第一次干燥、第二次浸渍处理、第二次干燥制得高色牢度饰面层；第二次浸渍处理时先后添加红外反射二氧化钛、2-咪唑烷酮；
S2、将制成的高色牢度饰面层与缓冲平衡层单板复合进行热压；
S3、将基板层上下两表面涂环保胶，再将步骤S2制成的板复合在涂有环保胶的基板层上下两表面上进行预压；
S4、将步骤S3预压后的板坯进行热压制得力学生态板。
优选地，所述红外反射二氧化钛粒径为1000nm-1500nm，TiO2含量为85％-95％，表面包覆层SiO2与Al2O3的含量为5-15％。
优选地，所述导热填料为氧化镁、氧化铝、氢氧化镁、氮化硼、氮化铝中的一种或两种，所述导热填料的粒径在0.3um-1.7um，纯度大于98％。
优选地，所述的光稳定剂为水杨酸酯、二苯甲酮、三嗪类、苯并三唑类的UV吸收剂以及受阻胺类自由基捕捉剂中的一种或多种混合物。
优选地，所述溴系阻燃剂为四溴双酚A、十溴二苯乙烷、亚乙基-(双四溴邻苯二甲酰亚胺)、溴化环氧按质量比4∶2∶1∶1。
优选地，所述阻燃协效剂为硼酸锌、三氧化二锑、五氧化二锑、锑酸钠和氧化钼中的一种或多种物质的混合物。
优选地，所述耐化学品改性剂为含有全氟烷基的丙烯酸系添加剂。
优选地，所述缓冲平衡层为杨木单板、桉木单板或科技木单板；所述基板层为多层胶合板或细木工板中的一种，所述高色牢度饰面层粘合于缓冲平衡层上面。
优选地，所述环保胶为乙酰化魔芋胶、2-氨基-5-氯吡嗪、S-苄基硫脲盐酸盐、纳米纤维素溶液按照质量比15-40∶1-3∶5-10∶80-100共混而成的胶粘剂。
本发明还提供了一种力学生态板，通过上述的力学生态板的制作方法制作所得。
本发明具有以下有益效果：
采用红外反射钛白粉，可以大幅度反射太阳光的可见光和红外部分能量，加之导热填料的热释放的协同贡献，可以使较大幅度地降低板材的表面温度，从而提高板材的耐光色牢度，引入全氟烷基的丙烯酸系添加剂作为耐化学品改性剂，该添加剂的迁移效率极高，在板材制备的过程中即可完全迁移到板材表面形成一种保护膜，这层保护膜和水不相容且具有较强的耐酸碱的性能，从而添加了该类添加剂的板材在遇到外饰漆等较强腐蚀漆时，表面会存在巨大的表面张力，阻止了强腐蚀漆进入到材料内部；采用自制的环保胶，该环保胶具有较好的韧性以及环保性。
