技术领域
本发明涉及铝单板技术领域,具体为一种水性油漆铝单板及其涂装工艺。
背景技术
铝单板从规格上分为两种:厚度在1.2mm以下的铝单板称为铝扣板(也叫铝方板),厚度在1.5mm以上的铝单板称为铝单板。从表面处理分为三种分别为聚酯粉末喷涂、聚酯油漆喷涂、氟碳油漆喷涂。
其构造主要由面板、加强筋和角码组成。角码可直接由面板折弯、冲压成型,也可在面板的小边上铆装角码成型。加强筋与板面后的电焊螺钉(螺钉是直接焊在板面背面的)连接,使之成为一个牢固的整体,极大增强了铝单板幕墙的强度与刚性,保证了长期使用中的平整度及抗风抗震能力。如果需要隔音保温,可在铝板内侧安装高效的隔音保温材料。
现有的铝单板表面通常裸露,耐候性不强,一些涂覆涂料的铝单板也因其污染大,影响使用的健康性。
发明内容

实施例:
请参阅图1-4,本发明提供一种技术方案:一种水性油漆铝单板,包括:
铝制框架1,所述铝制框架1为角板焊接成型的四边框架形状;
其中,铝制框架1包括内合金基板11和均匀涂覆在内合金基板11外壁上的水性油漆层12;
水性油漆层12采用以下三类任意一种:
第一种,是以丙烯酸为主要成分的水性木器漆,主要特点是附着力好,不会加深木器的颜色,但耐磨及抗化学性较差,漆膜硬度较软,铅笔法测试为HB,丰满度较差,综合性能一般,施工易产生缺陷。。
第二种,是以丙烯酸与聚氨酯的合成物为主要成分的水性木器漆,其特点除了秉承丙烯酸漆的特点外,又增加了耐磨及抗化学性强的特点,有些企业标为水性聚脂漆。漆膜硬度较好,铅笔法则试为1H,丰满度较好,综合性能接近油性漆。
第三种,是聚氨酯水性漆,其综合性能优越,丰满度高,漆膜硬度可达到1.5-2H,耐磨性能甚至超过油性漆,使用寿命、色彩调配方面都有明显优势,为水性漆中的高级产品。
设置在铝制框架1内侧的铝制网板2。铝制框架1、铝制网板2均为铝合金材质。
优选的,所述铝制框架1内下侧设置有螺杆3,在所述螺杆3的外壁上螺接有紧固螺母4,所述铝制网板2的四角均开设有定位孔,所述定位孔套在螺杆3上,且紧固螺母4支撑在铝制网板2的下表面。
优选的,所述螺杆3为中空的管状,且在螺杆3的本体上开设有滑槽,所述螺杆3的下侧设置有能够将螺杆3下侧沿着滑槽扩张的分离组件5。
优选的,所述分离组件5包括圆台式推板51,所述圆台式推板51的外壁倾斜面与螺杆3下侧接触,所述圆台式推板51的上表面中部连接有拉杆52,所述拉杆52插接在螺杆3的内部,所述拉杆52的上端外侧通过滑杆53固定连接滑动圈54,所述滑杆53贯穿滑槽并延伸至外侧,所述滑动圈54滑动套在螺杆3的外侧,且滑动圈54支撑在紧固螺母4的上表面。
优选的,在所述螺杆3的外壁上侧套接有支撑在铝制框架1、铝制网板2之间的缓冲垫圈。
优选的,所述铝制框架1、铝制网板2之间焊接。
一种水性油漆铝单板的涂装工艺,该水性油漆铝单板的涂装工艺的具体步骤如下:
S1:将铝单板表面清理:将铝制框架1及铝制网板2表面预先通过磨砂纸对其打磨,将铝制框架1及铝制网板2表面打磨出摩擦纹且将铝制框架1及铝制网板2表面的毛刺清理;
S2:喷涂漆料:将步骤S1中清理、打磨后的铝制框架1及铝制网板2表面均匀喷涂水性油漆;
用洁净的水将涂料调至合适喷涂的粘度,以涂-4粘度计测量,合适的粘度一般是20~30秒。如一时没有粘度计,可用目测法:用棒(铁棒或木棒)将涂料搅匀后挑起至20厘米高处停下观察,如漆液在短时间(数秒钟)内不断线,则为太稠;如一离桶上沿即断线则为太稀;要在20厘米高处刚停时,漆液成一直线,瞬间即断流变成往下滴,这个粘度较为合适。
空气压力最好控制在0.3-0.4兆帕(3-4公斤力/平方厘米)。压力过小,漆液雾化不良,表面会形成麻点;压力过大易流挂,且漆雾过大,既浪费材料又影响操作者的健康。
喷嘴与物面的距离一般以300-400毫米为宜。过近易流挂;过远漆雾不均匀,易出现麻点,且喷嘴距物面远漆雾在途中飞散造成浪费。距离的具体大小,应根据涂料的种类、粘度及气压的大小来适当调整。慢干漆喷涂距离可远一点,快干漆喷涂,距离可近一点;粘度稠时可近一点,粘度稀时可远一点;空气压力大时,距离可远一点,压力小时可近一点;所谓近一点远一点是指10毫米-50毫米之间小范围的调整,若超过此范围,则难以获得理想的漆膜。
喷枪可作上下、左右移动,最好以10-12米/分的速度均匀运作,喷嘴要平直于物面喷涂,尽量减少斜向喷涂。当喷到物面两端时,扣喷枪扳机的手要迅速的松一下,使漆雾减少,因为物面的两端,往往要接受两次以上的喷涂,是最容易造成流挂的地方。
喷涂时要下一道压住上一道的1/3或1/4,这样才不会出现漏喷现象。在喷涂快干漆时,需一次按顺序喷完。补喷效果不理想。
在室外空旷的地方喷涂时,要注意风向(大风时不宜作业),操作者要站在顺风方向,防止漆雾被风吹到已喷好的漆膜上造成难看的粒状表面。
喷涂的顺序是:先难后易,先里后外。先高处后低处,先小面积后大面积。这样就不会造成后喷的漆雾飞溅到已喷好的漆膜上,破坏已喷好的漆膜。
S3:对漆料烘烤固化:将喷涂水性油漆的铝制框架1及铝制网板2置于恒温箱内烘烤使得水性油漆固化。
恒温箱内设定烘烤温度为100-120摄氏度,且烘烤时间为2-3小时,烘烤后,将铝制框架1、铝制网板2置于冷却箱中冷却,且冷却箱中中满惰性气体。
优选的,所述磨砂纸的粗糙程度为600-1000目。
