Preparation method of hydrophilic/hydrophobic coating nanometer thermal insulation material with controllable coating thickness
The invention discloses a preparation method of a hydrophilic/hydrophobic coating nano thermal insulation material with controllable coating thickness, and belongs to the technical field of nano thermal insulation material preparation. White oil is added into nano powder, and ball milling is performed to obtain modified nano powder; uniformly mixing the modified nano-powder with modified chopped fibers and a modification additive to obtain a composition A, and treating the composition A in a muffle furnace to obtain a composition B; mixing the composition A and the composition B according to equal mass proportion to obtain a composition C; laying the composition A, the composition B and the composition C in a mold according to a design sequence, and then carrying out die forming to obtain a nano thermal insulation material blank; and applying a hydrophilic/hydrophobic coating on the surface of the green body to obtain the nano thermal insulation material with the hydrophilic/hydrophobic coating. The problems of powder falling and the like of the nano heat insulation material are solved, and meanwhile, the surface strength of the nano heat insulation material is greatly improved.
本发明公开一种涂层厚度可控的亲水/疏水涂层纳米隔热材料的制备方法，属于纳米隔热材料制备技术领域，向纳米粉体中加入白油，球磨得到改性纳米粉体；将改性纳米粉体与改性短切纤维、改性助剂进行均匀混合得到组合物A，在马弗炉中处理得到组合物B；将组合物A、组合物B等比例质量混合得到组合物C；在模具内将组合物A、组合物B、组合物C按照设计顺序铺层，然后进行模压成形，得到纳米隔热材料坯料；再在坯体表面施加亲水/疏水涂料，得到带亲水/疏水涂层的纳米隔热材料。本发明解决了纳米隔热材料存在的掉粉等难题，同时纳米隔热材料表面强度大幅提升。
