Abstract

本发明公开了一种陶瓷表面改性方法，包括如下步骤：将碳纤维短切毡浸润热固性树脂得到碳纤维预浸布；将碳纤维预浸布裁切成陶瓷表面形状大小，置于模具的上下表面；将陶瓷粉末混合胶粘剂倒入模具中，压力条件下合模压制、保压成型；将成型后的改性陶瓷放入烧结炉内进行烧结；将烧结完成的改性陶瓷去除边缘多余的碳布，得到防弹陶瓷片成品。本发明通过在陶瓷板上下表面复合碳纤维短切毡，既改变了增强陶瓷表面的附着力，使得陶瓷与纤维防弹板牢固粘接，又可以使碳纤维有效的吸收陶瓷板着弹后传播的动能，阻止陶瓷裂缝的扩散，使得陶瓷板和纤维防弹板在使用整片法结合的同时又具备防御多发子弹的能力。

Description

一种陶瓷表面改性方法
技术领域
本发明涉及陶瓷复合材料领域，具体涉及一种陶瓷表面改性方法。
背景技术
在轻质防弹装置中广泛使用高硬度陶瓷材料作为防弹装制得硬质面板，可以有效抵御子弹的穿透。目前常用的材料有AL2O3、SiC、B4C陶瓷等，是以拼接或整片复合的方式覆盖在纤维防弹板表面。其中，拼接法防弹陶瓷块与纤维防弹板的结合部位无法完全吻合，拼接位置之间的形成的接缝容易被击穿，而且子弹产生的作用力也会随着接缝散开；整片法由于陶瓷的脆性，在防御多发子弹时，后几发的着弹区域的陶瓷会受前几发动能的影响而碎裂，无法防御。并且由于陶瓷表面的光滑导致胶粘剂的结合性能下降，使得陶瓷与纤维板无法牢固的粘接。
发明内容
为了克服上述技术问题，本发明提供了一种陶瓷表面改性方法，我们将采用如下的技术方案予以实施：
一种陶瓷表面改性方法，包括如下步骤：
S1：将碳纤维短切毡浸润热固性树脂得到碳纤维预浸布；
S2：将S1中的碳纤维预浸布裁切成陶瓷表面形状大小，置于模具的上下表面；
S3：将陶瓷粉末混合胶粘剂倒入模具中，压力条件下合模压制、保压成型；
S4：将成型后的改性陶瓷放入烧结炉内进行烧结；
S5：将S4中烧结完成的改性陶瓷去除边缘多余的碳布，得到防弹陶瓷片成品。
优选地，步骤S1中所述的热固性树脂为环氧树脂或酚醛树脂，热固性树脂加入量为碳纤维短切毡质量的43-54％。
优选地，步骤S3中胶粘剂加入量为陶瓷粉末质量的2％-5％。
优选地，成型压力为120-160MPa，保压时间为70-100s。
优选地，步骤S4中的烧结温度为2000-2300℃。
本发明的有益效果如下：
(1)本发明通过在陶瓷板上下表面复合碳纤维短切毡，通过高温与陶瓷烧结为一体，改变增强陶瓷表面的附着力使得陶瓷与纤维防弹板牢固粘接。
(2)碳纤维的强度可以有效的吸收陶瓷板着弹后传播的动能，阻止陶瓷裂缝的扩散，使得陶瓷板和纤维防弹板在使用整片法结合的同时又具备防御多发子弹的能力。
具体实施方式
下面结合具体实施例来对本发明做进一步的解释和说明，以使本发明的优点和特征更容易被本领域的技术人员理解。
实施例1
一种陶瓷表面改性方法，包括如下步骤：
S1：将碳纤维短切毡浸润酚醛树脂得到碳纤维预浸布，酚醛树脂加入量为碳纤维短切毡质量的52％；
S2：将S1中的碳纤维预浸布裁切成陶瓷表面形状大小，置于模具的上下表面；
S3：将陶瓷粉末混合胶粘剂倒入模具中，压力条件下合模压制、保压成型；胶粘剂加入量为陶瓷粉末质量的3％，成型压力130MPa，保压时间75s；
S4：将成型后的改性陶瓷放入烧结炉内在2150℃下进行烧结；
S5：将S4中烧结完成的改性陶瓷去除边缘多余的碳布，得到防弹陶瓷片成品。
实施例2
一种陶瓷表面改性方法，包括如下步骤：
S1：将碳纤维短切毡浸润环氧树脂得到碳纤维预浸布，环氧树脂加入量为碳纤维短切毡质量的48％；
S2：将S1中的碳纤维预浸布裁切成陶瓷表面形状大小，置于模具的上下表面；
S3：将陶瓷粉末混合胶粘剂倒入模具中，压力条件下合模压制、保压成型；胶粘剂加入量为陶瓷粉末质量的4％，成型压力150MPa，保压时间90s；
S4：将成型后的改性陶瓷放入烧结炉内在2300℃下进行烧结；
S5：将S4中烧结完成的改性陶瓷去除边缘多余的碳布，得到防弹陶瓷片成品。
对比例以实施例2的改性方法为基础，区别在于未包括S1和S2步骤。
将实施例1、实施例2和对比例获得的防弹陶瓷片进行力学性能测试，测试结果见表1所示。
其中，剥离强度测试是将防弹陶瓷片与纤维背板通过界面胶粘剂复合后，测量防弹陶瓷片与纤维背板结合在一起形成的层之间的剥离强度。
表1
实施例1 实施例2 对比例
硬度(kgf/mm<sup>2</sup>) 2450 2500 2640
剥离强度(kg) 17.21 17.52 10.066
断裂韧性(MPa/cm<sup>3</sup>) 6.8 7.6 3.2
抗压强度(MPa) 2850 2800 2700
由表1可以看出，采用本发明生产的防弹陶瓷片与对比例相比，具有更高的断裂韧性，表明本发明通过在陶瓷板上下表面复合碳纤维短切毡，制备的复合材料综合力学性能好，能够有效地降低陶瓷材料的脆性；而且防弹陶瓷片层与纤维背板层之间的剥离强度相对于对比例来说更大，表明碳纤维短切毡的引入改变了增强陶瓷表面的附着力，使得陶瓷与纤维防弹板之间粘接的更加牢固。
将实施例1、实施例2和对比例获得的防弹陶瓷片与纤维背板通过界面胶粘剂复合后进行弹道冲击试验，所得数据列于表2，其中所用弹体为7.62×39mm铅芯弹。
表2
由表2可知，本发明的防弹陶瓷片与纤维背板复合之后具有较好的子弹防御效果，而且陶瓷基体上下表面附着的碳纤维可以有效的吸收陶瓷板着弹后传播的动能，阻止陶瓷裂缝的扩散，使得陶瓷板和纤维防弹板在使用整片法结合的同时粘合力较强，而且又具备防御多发子弹的能力。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
虽然已经详细说明了本发明及其优点，但是应当理解在不超出由所附的权利要求所限定的本发明的精神和范围的情况下可以进行各种改变、替代和变换。而且，本申请的范围不仅限于说明书所描述的过程、设备、手段、方法和步骤的具体实施例。本领域内的普通技术人员从本发明的公开内容将容易理解，根据本发明可以使用执行与在此所述的相应实施例基本相同的功能或者获得与其基本相同的结果的、现有和将来要被开发的过程、设备、手段、方法或者步骤。因此，所附的权利要求旨在在它们的范围内包括这样的过程、设备、手段、方法或者步骤。
