Description

一种发泡塑料板材及其生产工艺
技术领域：
本发明涉及建筑板材领域，具体讲是一种发泡塑料板材及其生产工艺。
背景技术：
现有的墙板、吊顶板等通常使用密度板、装饰板，密度板和装饰板通常含有甲醛，无法满足日益增长的生活需求，而且环保性欠佳。
发明内容：
本发明所要解决的技术问题是，提供一种重量轻，脚感好的轻质塑胶地板地板。
本发明的技术解决方案是，提供一种发泡塑料板材，包括HDPE发泡层，HDPE发泡层的表面复合有高密度PP膜或喷涂有聚氨酯。
作为优选，HDPE发泡层也可以替代为PP或PE发泡层。
作为优选，包括以下组分，以重量份数计，HDPE 60-120份、发泡剂1-8份、硬脂酸2-5份、抗氧剂3-8份、紫外线吸收剂1-5份。
作为优选，还包括阻燃剂5-12份。
本发明还提供一种发泡塑料板材的生产工艺，包括以下步骤，
步骤一，搅拌，将物料混合搅拌，搅拌装置为搅拌机；
步骤二，熔融，将搅拌后的物料通过上料机吸入料筒中进行加热，加热温度为140-198℃，加热时间为30-60min,使物料熔融；
步骤三，模压，出料模连接出料筒的出料口，熔融的物料进入出料模中并转移到定型模，物料在定型模中进行模压定型；
步骤四，定型的板材表面复合高密度PP膜或喷涂有聚氨酯。
进一步的，定型模根据产品需要可以在板材表面倒模出凹凸花纹。
进一步的，模压通过压机实现。
采用以上方案后与现有技术相比，本发明具有以下优点：本发明通过HDPE发泡定型，并根据需要复合表面层，实现耐磨、耐污等效果，同时，生产该产品的工艺简单易行，产品不含甲醛，非常环保。
附图说明：
图1为本发明的一个实施例的结构示意图。
具体实施方式：
下面就具体实施方式对本发明作进一步说明：
实施例一
如图1所示，一种发泡塑料板材，包括HDPE发泡层1，HDPE发泡层1的表面喷涂有聚氨酯2，HDPE发泡层包括以下组分，以重量份数计，HDPE90份、HDPE发泡剂3份、硬脂酸2份、抗氧剂4份、紫外线吸收剂3份，还包括阻燃剂6份，其中紫外线吸收剂包括UV-531和UV-770，抗氧剂为抗氧剂1010，阻燃剂为纳米氧化锌。其生产工艺包括以下步骤，
步骤一，搅拌，将物料混合搅拌，搅拌装置为搅拌机，搅拌时间3-10min；
步骤二，熔融，将搅拌后的物料通过上料机吸入料筒中进行加热，加热温度为140-198℃，加热时间为30-60min,使物料熔融；
步骤三，模压，出料模连接出料筒的出料口，熔融的物料进入出料模中并转移到定型模，物料在定型模中利用压机进行模压定型，保持定型模内模温为60℃-90℃，模压为0.3MPa-0.8MPa，在此过程中，还进行退火处理；
步骤四，定型的板材表面喷涂有聚氨酯。
另外，根据产品需要，对定型模进行处理，定型模根据产品需要可以在板材表面倒模出凹凸花纹。
实施例二
与实施例一不同的是，HDPE发泡层的表面复合有高密度PP膜，复合方式可以为热压，也可以为粘接复合。其生产工艺步骤中步骤一到步骤三与实施例一相同，步骤四中定型的板材表面复合高密度PP膜。从而形成发泡塑料板材，用于建筑材料中的墙板，吊顶板等。本产品重量轻，而且不含甲醛。
以上仅就本发明较佳的实施例作了说明，但不能理解为是对权利要求的限制。凡是利用本发明说明书所做的等效结构或等效流程变换，均包括在本发明的专利保护范围之内。
