Description

一种软管及其制造方法 技术领域
本发明涉及管道技术领域，具体涉及一种软管及其制造方法。
背景技术
水管是人们日常生活中都会接触的物品之一，一般的水管长度及粗细都是固定不变的，因此，在使用过程中，当在洗车、浇灌园林花艺等场合需要传输水等液体时，如果所用地与水源地相距甚远，通常需要比较长的管道，这样水管在使用中，可能会经过多处摩擦和拐角，加大管壁的磨损，容易造成漏水等现象，且管道的长度通常固定不变，因此在使用水管中，会有诸多不便，给人们带来很多麻烦，同时由于生产软管的技术方法仍然是传统的一体成型工艺，如果水管的一个部分损坏就会导致整个水管的报废，也会对水管材料的资源以及经济造成极大的浪费。
发明内容
本发明提供一种软管及其制造方法，能够解决上述技术问题的一个或者多个。
根据本发明的一个方面，本发明提供一种软管，包括弹簧耐磨管、编织外管、防水层和橡胶内管，弹簧耐磨管套设于编织外管外侧，编织外管的外部表面上涂覆有防水层，编织外管内部套设有橡胶内管。通过在编织外管外侧套设有弹簧耐磨管，可以防止编织外管直接与地面接触摩擦，提高了软管整体的耐磨性，同时在同时在编织外管外表面涂覆有防水层，还可以提高软管整体的防水性与密封性，极大的延长了软管的使用寿命。
在一些实施方式中，还包括耐磨层，耐磨层固定在编织外管的内壁上。通过在编织外管内壁上设置有耐磨层，防止编织外管直接跟橡胶内管摩擦，提高了橡胶内管的使用寿命。
在一些实施方式中，弹簧耐磨管由塑料或者金属合金制成。通过塑料或者金属合金制成弹簧耐磨管，能够极大的提高弹簧耐磨管的耐磨程度。
在一些实施方式中，编织外管的长度长于橡胶内管的长度，编织外管的两端与橡胶内管的两端固定后编织外管呈褶皱状。编织外管比橡胶内管长同时比橡胶内管外径大，可以方便橡胶内管的拉伸和膨胀。
在一些实施方式中，橡胶内管具有弹性，橡胶内管在充入液体膨胀后编织外管的褶皱消失。在充入液体后编织外管褶皱消失能够对橡胶内管的压力起到一定的控制作用，防止橡胶内管压力过大，发生爆裂。
根据本发明的一个方面，提供一种软管的制造方法，包括如下步骤：
步骤1、制备弹簧耐磨管，将硬性塑料条制成螺旋状，形成弹簧耐磨管；
步骤2、制备编织外管，将化纤纤维通过编织制成编织外管；
步骤3、涂覆防水层，将编织外管加热干燥后浸入液体状的防水剂中，随后取出编织外管并放入烘箱中烘干防水剂，形成防水层；
步骤4、制备耐磨层，将软性高强度塑料制成管状的耐磨层；
步骤5、粘合编织外管与耐磨层，将耐磨层通过粘合剂粘接在编织外管的内壁上；
步骤6、制备橡胶内管，先将橡胶原料制成内部呈中空的管状体，然后再将管状体放入烘箱中加热硫化，硫化结束后制成所述橡胶内管；
步骤7、组装弹簧耐磨管、编织外管和橡胶内管，先将橡胶内管穿入编织外管内并固定，再将编织外管穿入弹簧耐磨管内并固定。通过分别制造橡胶内管、编织外管和弹簧耐磨管，再进行组合安装，可以方便本发明的部件损坏时能够快速更换。
在一些实施方式中，步骤3中，编织外管加热干燥的温度为80℃，编织外管放入烘箱中烘干防水剂的温度为80℃。在此温度下方便防水剂涂覆在编织外管的表面，提高编织外管的防水性。
在一些实施方式中，步骤5中，耐磨层在高温高压条件下通过粘合剂粘接在编织外管的内壁上，温度为80℃～100℃，压力为0.1MPa～0.2MPa。在此温度和压力的环境下，方便耐磨层与编织外管的连接。
在一些实施方式中，步骤6中，管状体放入烘箱中的加热温度为120℃～140℃，硫化的时间为1小时～1.5小时。在此温度和硫化时间下，方便橡胶内管的制备。
在一些实施方式中，步骤7中，橡胶内管与编织外管通过设有外螺纹的 连接头固定，编织外管与弹簧耐磨管通过设有内螺纹的连接头固定。通过设有连接头方便编织外管与伸缩管的拆卸与连接。

具体实施方式
下面结合说明书附图，对本发明进行进一步详细的说明。

在一些优选方案中，如图3所示，还包括耐磨层4，耐磨层4固定在编织外管3的内壁上。进一步说，耐磨层4呈管状，编织外管3通过粘合剂粘贴套设于耐磨层4的外侧，使耐磨层4与编织外管3形成一个整体。通过设置耐磨层4可以防止编织外管3与橡胶内管5的直接摩擦而导致橡胶内管5的损坏，提高橡胶内管5的寿命。
在一些优选方案中，编织外管3的长度可以长于橡胶内管5的长度，编织外管3的两端与橡胶内管5的两端通过连接头固定后编织外管3呈褶皱状。橡胶内管5具有弹性，橡胶内管5在充入液体膨胀后编织外管3的褶皱消失。将编织外管3的长度设计成长于橡胶内管5的长度，可以方便橡胶内管5充入液体后的膨胀拉伸，起到限制橡胶内管5的作用，防止橡胶内管5膨胀爆 裂。
下面对本发明的制造方法做进一步详细描述。
如图4所示，本发明的制造方法包括如下步骤：
步骤1、制备弹簧耐磨管1，将硬性塑料条制成螺旋状，形成弹簧耐磨管1；进一步说，弹簧耐磨管1由硬性塑料条制备，并通过挤出机挤出形成弹簧螺旋圈，硬性塑料条为PVC、PU和TPE材料。
步骤2、制备编织外管3，将化纤纤维通过编织制成编织外管3；进一步说，此编织工艺通过经线1根和纬线2根通过编织机上交叉上下编织成圆筒状。
步骤3、涂覆防水层2，将编织外管3加热干燥后浸入液体状的防水剂中，随后取出编织外管3并放入烘箱中烘干防水剂，形成防水层2；在一些实施例中，将编织外管3放入烘箱中5分钟，在编织外管3表面达到80℃时，将其从烘箱中取出并浸入液体状的TPU防水剂中，使编织外管3的表面涂覆一层液体TPU防水剂形成的防水层2，再将带有TPU防水剂的编织外管3放入80℃的烘箱中烘干20分钟，使其编织外管3的外表面附着软性的防水层2，起到防水和防污作用。
步骤4、制备耐磨层4，将软性高强度塑料制成管状的耐磨层4；进一步说，软性高强度塑料可以为PVC、PU和TPE材料，耐磨层4通过水冷却形成。
步骤5、粘合编织外管3与耐磨层4，将耐磨层4通过粘合剂粘接在编织外管3的内壁上；进一步说，耐磨层4在高温高压条件下通过聚氨酯粘合剂粘接在编织外管3的内壁上，温度大约为80℃～100℃，压力大约为0.1MPa～0.2MPa。在温度为80℃，压力为0.1MPa时，编织外管3与耐磨层4可以较好的相互粘接同时也便于相互剥离；在温度为90℃，压力为0.15MPa时，编织外管3与耐磨层4能够达到最好的粘接状态；在温度为100℃，压力为0.2MPa时，编织外管3与耐磨层4能够牢固的粘接，不易相互剥离。
步骤6、制备橡胶内管5，先将橡胶原料制成内部呈中空的管状体，然后再将管状体放入烘箱中加热硫化，硫化结束后制成弹性橡胶内管5；进一步说，管状体放入烘箱中的加热温度大约为120℃～140℃，硫化的时间大约为 1小时～1.5小时。当加热温度为120℃，硫化时间为1小时，所形成的橡胶内管5弹性较小，适于使用在液体压力较小的环境中；当加热温度为130℃，硫化时间为1.25小时，所形成的橡胶内管5弹性适中，适于使用在传输大部分液体的环境中；当加热温度为140℃，硫化时间为1.5小时，适于使用在液体压力较大的场合。生产者可以根据产品使用环境的不同，灵活选择合适的加热温度与硫化时间，从而制造出不同的产品。
步骤7、组装弹簧耐磨管1、编织外管3和橡胶内管5，先将橡胶内管5穿入编织外管3内并固定，再将编织外管3穿入弹簧耐磨管1内并固定。作为一种优选方案，橡胶内管5与编织外管3通过设有外螺纹的连接头固定，编织外管3与弹簧耐磨管1通过设有内螺纹的连接头固定。通过螺纹方式连接各部件，有利于当其中一个部件损坏时的维修与更换。
以上所述仅是本发明的优选方式，应当指出，对于本领域普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干相似的变形和改进，这些也应视为本发明的保护范围之内。
