Description
技术领域
本发明属于材料领域，涉及一种水性阻尼浆的生产工艺。
背景技术
阻尼浆(阻尼涂料)是利用有机高分子材料所具有的粘弹性能，将声波的机械振动能转换为热能释放出来(即力学损耗)，从而达到减小振幅、降低振动，抑制噪声的目的。水性阻尼涂料具有良好的阻燃性、高附着力、耐腐蚀性、抗老化性、高阻尼性能且施工方便等优点，目前正被广泛应用在汽车、火车、轮船、飞机、工程机械和其他家用电器领域，起到隔音、吸声、减震和保温的效果。
水性阻尼浆原材料通常包括液态和固态的材料，传统的阻尼浆生产过程中在固态粉末材料的传送以及固液混合搅拌的过程中会产生大量的粉尘，粉尘不仅污染环境，而且对操作人员的健康不利，并且粉尘浓度过大会有一定的安全隐患，因此生产阻尼浆的工艺有待优化。
发明内容
为了解决现有技术的问题，本发明提供了一种水性阻尼浆的生产工艺，采用无尘投料站、负压输送系统以及螺带混合机等设备，在物料的传送过程以及混合的过程中避免了粉尘飞扬，改善了生产环境。
为了实现上述目的，本发明采用如下技术方案：
一种水性阻尼浆的生产工艺，包括以下步骤：
(1)原料输送：
1-1)液态原料输送：通过液体定量输送设备进行液态原料的定量输送；
1-2)固态原料输送：固态粉体原料称量后投入无尘投料站，然后通过气力输送系统输送；
(2)液固原料混合：液固原料的混合在螺带混合机中进行；
(3)称重出料：混合物料出料称重装入料筒；
(4)输出：成品输出。
所述步骤1-1)中液态原料定量输送是通过在传统的液体输送设备中安装质量流量计或者使用计量泵实现。
所述步骤1-2)气力输送系统为负压气力输送系统。
所述步骤1-2)中无尘投料站与气力输送系统连接，无尘投料站的出料口连接气力输送系统的进料口。
所述步骤(2)中固液原料混合的过程中，螺带混合机的参数设置为：转速10～100rpm，搅拌时间为1～8h。
所述步骤(3)中混合物料通过气动称重阀出料称重。
所述原料按照重量份计算，配比如下：水性纯丙乳液20～30份，水性苯丙乳液15～25份，无机填料20～40份，石墨烯0.5～1份，阻燃剂10～20份，成膜助剂5～20份，水性分散剂0.5～1.5份，水性消泡剂0.5～1.5份，水性润湿剂0.5～1.5份，防冻剂0.5～1.5份，防腐防霉剂0.5～1.5份，增稠剂0.5～1.5份。
所述无机填料为橡胶粉、云母粉、空心玻璃珠、高岭土、滑石粉、碳酸钙、二氧化硅、氧化铝、粘土、云母、硅藻土、氢氧化铝、珍珠粉、硫酸钡、碳酸镁、磷酸钙或无水硫酸镁中的一种或多种。
工作原理：
本生产过程通过集成化设计，并与现场常规操作相结合的控制方式，形成一个完整的采集、控制及管理系统，系统通过程序的设定，以及接收到的到位信号，连续稳定的完成送料、混合、出料等动作。
系统启动时，液体原料通过液体输送设备定量输送到螺带混合机，固态粉体原料称重后投入无尘投料站，无尘投料站中的原料直接进入气力输送系统，固态粉体原料在气力输送系统中获得加速度，输送至螺带混合机，螺带混合机对原料进行连续搅拌混合，原料混合均匀后，经出料口进入装料桶进行称重，之后成品输出。
有益效果：
(1)本发明阻尼浆的生产过程中使用无尘投料站，避免了传统投料的粉尘飞扬，投料站结构简单，操作方便；
(2)采用负压气力输送系统，由于是吸送，风机中如有油分或水分不会混入原料，避免了输送物料的污染，并且在整个输送过程中，不会有内部物料向外泄漏，生产卫生、安全；
(3)采用螺带混合机进行搅拌，搅拌过程中处于密闭状态，搅拌的物料不会弥散到车间，保持生产车间的环境卫生；
(4)生产过程通过集成化设计，并与现场常规操作相结合的控制方式，连续稳定的完成原料的输送、混合、称重和出料动作，生产效率高；
(5)产品中加入石墨烯，能够提高阻尼浆的防腐性能。
