Description

一种柔韧抗压型酚醛泡沫
技术领域
本发明涉及酚醛泡沫技术领域，尤其涉及一种柔韧抗压型酚醛泡沫。
背景技术
酚醛泡沫是以酚醛树脂和阻燃剂、抑烟剂、固化剂、发泡剂、及其它助剂等多种物质，经科学配方制成的闭孔型硬质泡沫塑料，最突出的特点是难燃、低烟、抗高温歧变，它可以现场浇注发泡、可模制、也可机械加工，可制成板材、管壳及各种异型产品，它克服了原有泡沫塑料型保温材料易燃、多烟、遇热变形的缺点，保留了原有泡沫塑料型保温材料质轻、施工方便等特点。
专利号为CN 202299221 U的公布了一种酚醛泡沫复合板，能够有效阻断酚醛泡沫层吸水，从而防止酚醛泡沫因吸水导致的变形、力学性能和保温性能下降等问题，另外，第一聚合物水泥基涂层避免了施工时直接接触酚醛泡沫，降低了由酚醛泡沫脆性大和易掉渣而导致的施工难度。
上述酚醛泡沫在使用过程中存在以下缺点1、酚醛泡沫由于其自身物理特性等原因，导致其抗压性较差，酚醛本身很脆，易粉化，导致其柔韧性较差，容易断裂；2、传统酚醛泡沫只具有单一的层体结构，在进行保温作用时，只能依靠酚醛泡沫自身的保温特性进行保温，导致在保温要求较高的环境下使用时其保温性能较差，为此，我们提出一种柔韧抗压型酚醛泡沫。
发明内容
本发明提供一种柔韧抗压型酚醛泡沫，旨在可以提高酚醛泡沫的柔韧性和抗压性，同时进一步提升酚醛泡沫的保温性能。
本发明提供的具体技术方案如下：
本发明提供的一种柔韧抗压型酚醛泡沫，包括泡沫主体，所述泡沫主体内部设有基体层，所述基体层内部一侧填充有增韧层A，所述基体层内部另一侧填充有增韧层B，所述泡沫主体内部开设有空腔，所述空腔内部填充有保温层。
可选的，所述基体层材质为酚醛泡沫。
可选的，所述增韧层A材质为橡胶，所述增韧层B材质为聚乙二醇热塑性树脂。
可选的，所述保温层材质为二氧化硅气凝胶垫。
本发明的有益效果如下：
1、泡沫主体的内部以基体层为主体，基体层材质为酚醛泡沫，基体层内部填充有增韧层A和增韧层B，增韧层A材质为橡胶，橡胶弹性体末端基有较高的活性，能与酚醛树脂中的轻甲基发生不同程度的接枝或嵌段共聚反应，易形成海岛结构，这种形态结构有利于材料在遭受外力冲击时，通过内部的弯曲变形来吸收外界冲击能，提升泡沫主体的抗冲击性，增韧层B材质为聚乙二醇热塑性树脂，其内部轻基与酚醛缩聚物中羟甲基易发生缩合接枝反应，形成接枝共聚物，改善酚醛树脂的脆性，提高泡沫主体的柔韧性，通过增韧层A和增韧层B的相互配合，提升酚醛泡沫的柔韧和抗压性，进而提升其适用范围。
2、泡沫主体内部开设有空腔且空腔内部填充有保温层，保温层材质为二氧化硅气凝胶垫，其孔径尺寸低于常压下空气分子平均自由程，因此在气凝胶空隙中空气分子近似静止，从而避免了空气的对流传热，而气凝胶极低的体积密度及纳米网格结构的弯曲路径也阻止了气态和固态热传导，因此具有极强的保温隔热性能，填充在泡沫主体内部，进一步提升了酚醛泡沫的保温性能。

使用时，泡沫主体1的内部以基体层2为主体，基体层2材质为酚醛泡沫，基体层2内部填充有增韧层A3和增韧层B4，增韧层A3材质为橡胶，橡胶弹性体末端基有较高的活性，能与酚醛树脂中的轻甲基发生不同程度的接枝或嵌段共聚反应，易形成海岛结构，这种形态结构有利于材料在遭受外力冲击时，通过内部的弯曲变形来吸收外界冲击能，提升泡沫主体1的抗冲击性，增韧层B4材质为聚乙二醇热塑性树脂，其内部轻基与酚醛缩聚物中羟甲基易发生缩合接枝反应，形成接枝共聚物，改善酚醛树脂的脆性，提高泡沫主体1的柔韧性，通过增韧层A3和增韧层B4的相互配合，提升酚醛泡沫的柔韧和抗压性，进而提升其适用范围，泡沫主体1内部开设有空腔5且空腔5内部填充有保温层6，保温层6材质为二氧化硅气凝胶垫，其孔径尺寸低于常压下空气分子平均自由程，因此在气凝胶空隙中空气分子近似静止，从而避免了空气的对流传热，而气凝胶极低的体积密度及纳米网格结构的弯曲路径也阻止了气态和固态热传导，因此具有极强的保温隔热性能，填充在泡沫主体1内部，进一步提升了酚醛泡沫的保温性能。
