Description

防盗门用耐冲压仿木纹覆膜板
技术领域
本发明涉及一种覆膜板,具体涉及一种防盗门用耐冲压仿木纹覆膜板。
背景技术
由于覆膜板在家装建材领域的应用范围日趋扩大,覆膜板的产品种类也呈现出五花八门。但是,由于覆膜板的设备投入资金相对较低,使得一些低技术含量的生产厂家也进入到了这一领域,出于对成本的控制和对利润的追求,一些厂家生产出的覆膜板出现了质量或环保等问题。
防盗门用仿木纹覆膜板需要具备一定的抗刮耐磨性能、耐冲压和抗冲击性,它需要与基板具备稳定的粘结强度,以防止其在长期使用后出现开裂等质量问题。然而,在现有技术中,大多数防盗门用的覆膜板仅仅是将膜层与基板采用热压形式粘结,由此获得的这种覆膜板在抗刮性、耐候性、耐冲压和抗冲击性等方面都相对较差,无法满足长期使用的需求。
发明内容
针对现有技术的不足之处,本发明的目的在于提供一种防盗门用耐冲压仿木纹覆膜板。
本发明的技术方案概述如下:
一种防盗门用耐冲压仿木纹覆膜板,其从上至下依次设有仿木纹PVC层、耐冲压层和钢板层;
其中,所述耐冲压层包括以下重量份的材料:
优选的是,所述的防盗门用耐冲压仿木纹覆膜板,其中,所述氯醋树脂中,醋酸乙烯单体的占比为38~42wt%。
优选的是,所述的防盗门用耐冲压仿木纹覆膜板,其中,所述氯醋树脂的数均分子量为28000~30000g/mol。
优选的是,所述的防盗门用耐冲压仿木纹覆膜板,其中,所述松香改性酚醛树脂的数均分子量为13000~15000g/mol。
优选的是,所述的防盗门用耐冲压仿木纹覆膜板,其中,所述耐冲压层中还包括有3-4重量份的环氧树脂。
优选的是,所述的防盗门用耐冲压仿木纹覆膜板,其中,所述环氧树脂的数均分子量为9000~10000g/mol。
优选的是,所述的防盗门用耐冲压仿木纹覆膜板,其中,所述耐冲压层中还包括有2~3重量份的2-甲基苯磺酸甲酯。
本发明的有益效果是:本案通过对防盗门用仿木纹覆膜板所用材料配方的改进,不仅使防盗门用仿木纹覆膜板自身具有良好的外观美观度,而且还具有高强度、高韧性、耐冲压性和抗刮耐磨性能,长期在高温、潮湿环境或紫外环境下膜层与基材的附着力好,不开裂剥落,不起泡。
具体实施方式
下面结合实施例对本发明做进一步的详细说明,以令本领域技术人员参照说明书文字能够据以实施。
本案提出一实施例的防盗门用耐冲压仿木纹覆膜板,其从上至下依次设有仿木纹PVC层、耐冲压层和钢板层;现有技术是将仿木纹PVC层和钢板层直接热压粘结,这种方式获得的产品性能相对较差,易开裂,抗冲压性能较差,使得板材的使用寿命受到限制。本案在这两层之间增加了一层耐冲压层,它可以起到过渡和衔接的作用,提高板材整体的耐冲压性能,增加板材的使用寿命。
其中,耐冲压层包括以下重量份的材料:
耐冲压层的配方以氯醋树脂为主体,氯醋树脂本身对金属和PVC材料具有良好的粘结性能,且其自身具备较高的抗冲压性能,能够增加板材的韧性和抗弯强度;松香改性酚醛树脂用于改善氯醋树脂体系的内聚力和热压粘度,从而增加板材的抗冲压性能;对氯苯甲酸正丁酯用于提高对钢板表面的粘结强度,以使得钢板可以免去钝化这一工序;羧甲基纤维素钠作为填料可以提高板材整体的刚性,同时,它可以减小板材的表面收缩应力,以提高板材的抗冲压和抗冲击性能;硅粉作为填料,既可以增加板材的弯曲韧性,又能减小耐冲压层的热膨胀系数,从而增加板材的结构稳定性。
其中,在氯醋树脂中,醋酸乙烯单体的占比优选为38~42wt%,余量为氯乙烯单体。氯醋树脂,亦称氯醋共聚物,是氯乙烯与醋酸乙烯的共聚物,由氯乙烯单体跟醋酸乙烯单体在引发剂的作用下共聚而得。通过对两种单体的比例进行限定,可以获得更优性能的氯醋树脂体系。
其中,氯醋树脂的数均分子量优选为28000~30000g/mol。
其中,松香改性酚醛树脂的数均分子量优选为13000~15000g/mol。本案无需限定松香改性酚醛树脂中松香的占比。
其中,耐冲压层中还优选包括有3-4重量份的环氧树脂。少量的环氧树脂可以增加耐冲压层在被热压时对钢板层和PVC层的初黏力,以进一步增加板材的结构稳定性。
其中,环氧树脂的数均分子量优选为9000~10000g/mol。
其中,耐冲压层中还优选包括有2~3重量份的2-甲基苯磺酸甲酯。2-甲基苯磺酸甲酯可以增加氯醋树脂体系在潮湿环境下的粘结持久力,同时,它还能使得氯醋树脂体系在77-90℃这一温度区间发挥较优的粘结力,因为这一温度区间正是PVC的最佳热压温度区间(热压强度10MPa)。

表二列出不同对比例的耐冲压层的具体配方和制得的防盗门用耐冲压仿木纹覆膜板的性能测试参数:
表二
尽管本发明的实施方案已公开如上,但其并不仅仅限于说明书和实施方式中所列运用,它完全可以被适用于各种适合本发明的领域,对于熟悉本领域的人员而言,可容易地实现另外的修改,因此在不背离权利要求及等同范围所限定的一般概念下,本发明并不限于特定的细节。
