Preparation method of multi-curved-surface bulletproof plate
The invention provides a preparation method of a multi-curved-surface bulletproof plate, and the preparation method of the multi-curved-surface bulletproof plate comprises the following steps: S1, putting diamond, phenolic resin, silicon powder, graphite powder, boron carbide and silicon carbide into a mixer, and uniformly mixing to obtain a mixture; s2, pressing the mixture into a sample; and S3, siliconizing and firing: carrying out modification pretreatment on silicon particles for siliconizing and firing, then carrying out siliconizing and firing on the sample, and separating the sample from the silicon particles by using an aluminum oxide plate during siliconizing and firing. According to the method, the silicon particles are pretreated, so that a thin graphite layer is adhered to the surfaces of the silicon particles, the silicon particles wrapped by the graphite firstly react with the graphite to generate a silicon carbide layer in the siliconizing firing process, and then the silicon particles form silicon steam and break through silicon carbide on the surface layer to be in contact with the sample to react, so that only a silicon carbide empty shell exists on the surface of the sample; surface treatment is very easy by adopting a sand blasting mode; according to the method, the sample and the silicon block are separated by the aluminum oxide plate during siliconizing firing, the aluminum oxide plate can be burnt during firing, and almost no silicon is left on the surface of a finished product after firing is completed.
本发明提出了一种多曲面防弹板的制备方法，一种多曲面防弹板的制备方法，包括如下步骤：S1、将金刚石、酚醛树脂、硅粉、石墨粉、碳化硼、碳化硅放入混料机里混匀，制得混合物；S2、将混合物压制成样品；S3、渗硅烧制：将用于渗硅烧制的硅粒经过改性预处理，之后将样品进行渗硅烧制，并在渗硅烧制时用氧化铝板把样品和硅粒隔开。本发明通过对硅粒的预处理，使得在硅粒表面粘附上一层薄薄的石墨，在渗硅烧制过程中被石墨包裹的硅粒会首先和石墨反应生成碳化硅层，然后硅粒形成硅蒸汽并突破表层的碳化硅与样品接触进行反应使得样品表面只有碳化硅空壳，采用喷砂的方式极易进行表面处理；本发明通过在渗硅烧制时用氧化铝板把样品和硅块隔开，烧制时氧化铝板会被烧解，烧制完成时成品表面几乎不会有硅的残留。
