Description

一种封头制备工艺
技术领域
本发明涉及一种封头制备工艺。
背景技术
采用无碱玻纤布制备封头时,一般是通过真空引流的方法来实现的。现有的真空引流方法中,由于导流网上的路径错综复杂,引导至无碱玻纤布表面的树脂十分不均,导致无碱玻纤布对树脂的吸收不够均匀,影响成品的强度质量。同时,导流网在脱模时会粘接在无碱玻纤布上,不仅需要耗费较多的人工进行脱离,脱模后还会影响产品的表面质量。
发明内容
本发明的目的是提供一种封头制备工艺,能够均匀的将树脂导流至无碱玻纤布层的表面各处,脱模时能够轻易的将导流网层剥离。
为达到上述目的,本发明采用的技术方案是:
一种封头制备工艺,包括以下步骤:
(1)在模具内侧铺设封闭层;
(2)沿所述封闭层的径向铺设并粘接无碱玻纤布层,环绕所述封闭层铺设至少一圈;
(3)在所述无碱玻纤布层上铺设表面均匀的设有小孔的导流膜层;
(4)在所述导流膜层上铺设表面设有纹路的导流网层;
(5)在所述导流网层上螺旋铺设螺旋管,在所述螺旋管上间隔均匀的开设多个出料口,并开设进料口;
(6)在所述导流网层上铺设环形管,在所述环形管上间隔均匀的开设多个进气口,并开设抽气口;所述进气口高于所述出料口;
(7)在所述导流网层上铺设真空袋层;
(8)通过所述抽气口抽真空,接着通过所述进料口输入树脂,当树脂被抽入环形管中时,停止抽真空并停止输入树脂;
(9)等待树脂固化后脱模。
优选地,在步骤(1)之前,在模具内侧涂覆脱模剂。
优选地,在步骤(1)之前,在模具内侧铺设脱模层。
优选地,在步骤(8)中,输入树脂前,对真空度进行测试,当真空度达标后,通过所述进料口输入树脂。
优选地,设置与进料口连通的进料管,并设置与抽气口连通的抽气管,使所述进料管和所述抽气管均穿出所述真空袋层且与所述真空袋层密封连接。
优选地,使所述环形管与所述螺旋管同轴延伸,且高于所述螺旋管。
由于上述技术方案的运用,本发明与现有技术相比具有下列优点:本发明一种封头制备工艺,通过在螺旋管上间隔均匀的开设多个出料口,使树脂能够均匀的被导流至导流网层上;通过设置表面均匀的设有小孔的导流膜层,能够均匀的将树脂导流至无碱玻纤布层的表面各处,使无碱玻纤布层对树脂的吸收较为均匀,提高成品的强度质量;通过在无碱玻纤布层和导流网层之间设置导流膜层,脱模时能够轻易的将导流网层剥离,不仅减少了脱模的人工,同时提高了成品的表面质量。
附图说明
附图1为应用本发明方法装置的结构示意图;
附图2为应用本发明方法装置的剖视图。
其中:1、模具;2、封闭层;3、无碱玻纤布层;4、导流膜层;5、导流网层;6、真空袋层;7、螺旋管;8、出料口;9、进料口;10、环形管;11、进气口;12、抽气口;13、脱模层。
具体实施方式
下面结合附图来对本发明的技术方案作进一步的阐述。
参见图1-2所示,上述一种封头制备工艺,包括以下步骤:
(1)在模具1(该模具1的径向截面为半圆形或弧形)内侧涂覆脱模剂或铺设脱模层13;
(2)在脱模层13上铺设封闭层2;在本实施例中,封闭层2为胶衣层,通过设置胶衣层,对制得的封头外侧起到了表面封闭和保护的作用;
(3)沿封闭层2的径向铺设并粘接无碱玻纤布层3,环绕封闭层2铺设至少一圈;在本实施例中,为了使粘接更为平整,提高吸收树脂的均匀度以提高产品质量,该无碱玻纤布层3为沿封闭层2径向延伸的布条,根据实际需要,将多条布条环绕封闭层2铺设至少一圈,使其整体平整伏贴;
(4)在无碱玻纤布层3上铺设表面均匀的设有小孔的导流膜层4;显然,该导流膜层4的材质使其易于从无碱玻纤布层3上脱离;
(5)在导流膜层4上铺设表面设有纹路的导流网层5;该导流网层5用于通过其表面的路径来对树脂进行导流;
(6)在导流网层5上螺旋铺设螺旋管7,在螺旋管7上间隔均匀的开设多个出料口8,并开设进料口9;通过设置多个间隔均匀的出料口8,使树脂能够均匀的被导流至导流网层5上;
(7)在导流网层5上铺设环形管10,在环形管10上间隔均匀的开设多个进气口11,并开设抽气口12;进气口11高于出料口8;在本实施例中,使环形管10与螺旋管7同轴延伸,且高于螺旋管7,通过这个设置,使抽气口12位于进料口9的上方,由于树脂被导流网层5和导流膜层4均匀导流至无碱玻纤布层3各处,只有在无碱玻纤布层3吸附饱和后,树脂才会被抽入真空机构中;
(8)在导流网层5上铺设真空袋层6;该真空袋层6应整体覆盖模具1边缘,将下方各层均罩设其中;在本实施例中,通过密封胶带粘接真空层;
(9)设置与进料口9连通的进料管,并设置与抽气口12连通的抽气管,使进料管和抽气管均穿出真空袋层6,且两者的周向侧部均与真空袋层6之间密封连接;
(10)通过抽气口12抽真空,并对真空度进行测试,当真空度达标后,通过进料口9输入树脂,当树脂被抽入环形管10中时,停止抽真空并停止输入树脂;此时无碱玻纤布层3已经吸附饱和;
(11)等待树脂固化后,撕开真空袋层6,同时剥离导流网层5和导流膜层4,并通过脱模层13将产品与模具1脱离即可。
上述实施例只为说明本发明的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施,并不能以此限制本发明的保护范围,凡根据本发明精神实质所作的等效变化或修饰,都应涵盖在本发明的保护范围内。
