Abstract

一种阀衬材料的制备方法，其特征在于主要包括以下步骤：首先，充分混合，将玻璃纤维、碳纤维、二硫化钼、聚四氟乙烯和不锈钢粉充分混合成混合物；其次，模压成型，将充分混合之后的混合物在15～20Mpa的压力下以及360～380℃的温度下模压成型；最后，冷却至室温。采用本方法制成的阀衬材料抗磨强度和硬度会大大的提高，由此制成的各种产品之后不易变形和磨损，其密封性也比较好，从而延长了产品的寿命。

Description

一种阀衬材料的制备方法
技术领域
本发明涉及新材料技术领域，具体是涉及一种阀衬材料的制备方法。 
背景技术
原来的阀衬材料主要是通过聚四氟乙烯加碳配置而成，其制备方法是直接将这两种材料模压成型。这种方法制备的阀衬材料呈黑色，抗磨强度和硬度都比较差，因此由该方法制备的阀衬材料做成的各种产品之后容易变形、磨损、密封性差，严重影响产品的寿命。 
发明内容
本发明针对现有技术的不足，提供一种阀衬材料的制备方法，该方法制成的阀衬材料抗磨强度和硬度会大大的提高。 
为了达到上述目的，本发明一种阀衬材料的制备方法，主要包括以下步骤： 
首先，充分混合，将玻璃纤维、碳纤维、二硫化钼、聚四氟乙烯和不锈钢粉充分混合成混合物； 
其次，模压成型，将充分混合之后的混合物在15～20Mpa的压力下以及360～380℃的温度下模压成型； 
最后，冷却至室温。 
优选地，所述混合物的重量百分比为：1～5％的玻璃纤维。5～10％的碳纤维，3～6％的二硫化钼，50～60％的聚四氟乙烯，以及25～40％ 的不锈钢粉。 
优选地，所述不锈钢粉的粒径小于100微米。 
优选地，所述混合物在15～20Mpa的压力下以及360～380℃的温度下模压成型的保温时间在5～10分钟之间。 
采用本方法制成的阀衬材料抗磨强度和硬度会大大的提高，由此制成的各种产品之后不易变形和磨损，其密封性也比较好，从而延长了产品的寿命。 
具体实施方式
以下结合具体实施例对本发明进行详细描述，但不作为对本发明的限定。 
首先，充分混合，将4％的玻璃纤维、7％的碳纤维、5％的二硫化钼、54％聚四氟乙烯和30％不锈钢粉充分混合成混合物；所述不锈钢粉的粒径小于100微米； 
其次，模压成型，将充分混合之后的混合物在15～20Mpa的压力下以及360～380℃的温度下模压成型，其保温时间为8分钟； 
最后，冷却至室温，即得到阀衬材料。 
采用本方法制成的阀衬材料抗磨强度和硬度会大大的提高，由此制成的各种产品之后不易变形和磨损，其密封性也比较好，从而延长了产品的寿命。 
以上已将本发明做一详细说明，但显而易见，本领域的技术人员可以进行各种改变和改进，而不背离所附权利要求书所限定的本发明的范围。
