技术领域
本发明涉及一种厨房吊顶专用膜，尤其涉及一种带自粘保护膜的抗油污可低温贴合高分子膜及其制作方法。
背景技术
厨房中由于每天都会产生油烟和其它油污，而这些油烟或者油污虽然大部分会被抽油烟机抽走，但是难免会有一部分没被抽油烟机抽走的油烟或者油污往上走直接被吊顶吸附，时间一长，吊顶板就会被油烟熏的发黑或者发黄，有些贴膜甚至直接开裂脱胶；
而且，目前普通的吊顶板一般是采用涂胶的方式对吊顶膜进行保护，涂胶方式不仅环保性差，而且成本高；
同时目前普通的吊顶膜与吊顶板粘结时，需要采用较高的温度进行贴合，影响贴膜速度。
发明内容
本发明为了解决上述现有技术中存在的缺陷和不足，提供了一种不仅可以很好的保护吊顶板和吊顶膜，而且环保性好，成本低，同时可以防止吊顶板被油污侵蚀，防止吊顶板发黑发黄，延长吊顶板和贴膜的使用寿命，还可以加快贴膜速度，提高使用效率的带自粘保护膜的抗油污可低温贴合高分子膜。

具体实施方式
下面结合附图对本发明作进一步详细的说明，但并不是对本发明保护范围的限制。
如图1和2所示，一种带自粘保护膜的抗油污可低温贴合高分子膜，包括低温高分子基层、印刷层5、防油污层7、膜保护层9、自粘料层10和自粘料保护层11。低温高分子基层外侧通过粘结剂粘结在印刷层5内侧，防油污层7内侧通过粘结剂粘结在印刷层5外侧，膜保护层9内侧通过第一胶水层8与防油污层7外层粘结在一起，低温高分子基层包括外层3、中间层2和内层1，自粘料层10内侧粘接在膜保护层9外侧，自粘料保护层11内侧通过粘结剂粘结在自粘料层10外侧。外层3外侧通过第二胶水层4粘结在印刷层5内侧，中间层2外侧通过粘结剂粘结在外层3内侧，内层1外侧通过粘结剂粘结在中间层2内侧，内层1内侧用于粘结在厨房吊顶板12上。内层1由下述质量份数的组分构成：高分子树脂30-40份，低温粘接料60-70份，增光剂0.3-0.5份，防粘剂3-5份。自粘料层10由下述质量分数的组分构成：环氧树脂80-90份，增粘树脂10-15份，弹性体1-2份。
自粘料保护层11为LDPE材料层、LLDPE材料层或者LDPE与LLDPE共混材料层。内层1由高分子树脂与低温粘接料共混后添加增光剂和防粘剂形成的可低温粘结层，可低温粘结层粘结在厨房吊顶板12上。
高分子树脂为杜邦高分子料905或者杜邦高分子料868，低温粘接料为EAA，所述增光剂为PAA。
环氧树脂为AD环氧树脂，增粘树脂为EVA，弹性体为POP弹性体。
外层3为LLDPE材料层、LDPE材料层或者LLDPE与LDPE共混材料层，中间层2为LLDPE材料层、LDPE材料层或者LLDPE与LDPE共混材料层。印刷层5与防油污层7之间设有印刷保护层6，印刷保护层6和膜保护层9均为PET材料层。防油污层7为防油污树脂层。
实施例1
内层1由下述质量份数的组分构成：高分子树脂30份，低温粘接料60份，增光剂0.3份，防粘剂3份。自粘料层10由下述质量分数的组分构成：环氧树脂80份，增粘树脂10份，弹性体1份。
实施例2
内层1由下述质量份数的组分构成：高分子树脂40份，低温粘接料70份，增光剂0.5份，防粘剂5份。自粘料层10由下述质量分数的组分构成：环氧树脂90份，增粘树脂15份，弹性体2份。

本发明在普通高分子膜上复合了一层自粘保护膜，代替传统的涂胶工艺，使得其不仅可以很好的保护吊顶膜和吊顶板，而且环保性好，保护成本低，同时还增加了防油污层，使得其可以防止吊顶板被油污侵蚀，防止吊顶板发黑发黄，延长吊顶板和贴膜的使用寿命；同时使用可低温粘结层，使得其可以在较低温度下直接贴合在厨房吊顶板上，从而加快贴膜速度，提高使用效率。
