Description

墙壁纸生产工艺
技术领域
本发明涉及壁纸加工，特别涉及一种墙壁纸生产工艺。
背景技术
墙壁纸随着国内家装市场的兴起而成为室内装饰的主要材料，其中浮雕型墙壁纸以独特的魅力备受青睐，然而由于浮雕型墙壁纸由于撒粒的厚度原因存在以下缺陷，撒粒厚度过厚，虽然立体感较强，但是浮雕颗粒容易脱落，对室内会造成影响，撒粒厚度过薄，虽然浮雕颗粒粘结牢固，但是造成立体效果较差，此外由于天气原因，浮雕型墙壁纸透气性以及防水性均较差。
发明内容
本发明的目的在于克服上述技术的不足，从而提供一种墙壁纸生产工艺，不仅具有良好的阻燃隔热效果，而且外表面强度高不易破损。
本发明所采用的技术方案是这样的：墙壁纸生产工艺，包括以下步骤：
S1:面层制作，将聚酯树脂、碳酸钙、二氧化钛以及颜料混合形成树脂浆料，在树脂浆料中加入增强纤维混合后进行模压形成SMC面层；
S2：装饰层制作，对复合模具进行加热，将SMC面层铺设在下模的模腔内，在上模的模腔内加入装饰颗粒，而后合模进行复合，压力控制为2-5兆帕，模具加热温度为100-120摄氏度；
S3：基层热发泡，在纸质基材上表面涂布聚氯乙烯PVC并进行热发泡处理形成基层；
S4：涂胶，在基层表面涂抹粘结剂；
S5：热复合，将基层与SMC面层进行热复合，压力控制为0.5-1兆帕；
S6：涂防护层，在装饰层表面上涂抹一层透明防护层；
S7： 烘干，通过烘干机对壁纸进烘干处理，烘干温度为95-105℃，烘干时间为20s。
进一步改进的是：所述粘结剂为含有改性剂的聚醋酸乙烯酯胶粘剂，且改性剂为聚乙烯醇缩醛。
进一步改进的是：步骤S1中增强纤维为玻璃纤维或者竹纤维。
进一步改进的是：步骤S1中，增强纤维与树脂浆料混合前经过剪短处理，增强纤维长度控制为3-5mm。
进一步改进的是：所述透明防护层为树脂层。
通过采用前述技术方案，本发明的有益效果是：将面层利用SMC制成，具有良好的强度，壁纸不易破损，且将装饰层直接加工在面层上，通过模压的方式进行，加工便利，颗粒的装饰层直接渗透进入SMC面层内不易脱落，此外基层采用发泡层，不仅具有良好的阻燃、隔热、隔音效果，而且提高了壁纸的柔软度。
具体实施方式
以下结合具体实施方式来进一步说明本发明。
本发明公开一种墙壁纸生产工艺，包括以下步骤：
S1:面层制作，将聚酯树脂、碳酸钙、二氧化钛以及颜料混合形成树脂浆料，在树脂浆料中加入增强纤维混合后进行模压形成SMC面层；
S2：装饰层制作，对复合模具进行加热，将SMC面层铺设在下模的模腔内，在上模的模腔内加入装饰颗粒，而后合模进行复合，压力控制为2-5兆帕，模具加热温度为100-120摄氏度；
S3：基层热发泡，在纸质基材上表面涂布聚氯乙烯PVC并进行热发泡处理形成基层；
S4：涂胶，在基层表面涂抹粘结剂；
S5：热复合，将基层与SMC面层进行热复合，压力控制为0.5-1兆帕；
S6：涂防护层，在装饰层表面上涂抹一层透明防护层；
S7： 烘干，通过烘干机对壁纸进烘干处理，烘干温度为95-105℃，烘干时间为20s。
其中，所述粘结剂为含有改性剂的聚醋酸乙烯酯胶粘剂，且改性剂为聚乙烯醇缩醛，聚乙烯醇缩醛可为聚乙烯醇缩甲醛，继而使粘结剂的耐水性和耐湿性提高，克服了传统的粘结剂因潮气而发生粘结强度下降的缺陷，也改善了传统的粘结剂的抗高温蠕变性，其改性方法可以是：将粘结剂用醋酸乙酯溶解稀释，将聚乙烯醇缩甲醛同样用醋酸乙酯溶解，随后这两者经混合、增塑后过滤，滤液则为改性后的粘结剂。
为了提高面层的强度，步骤S1中增强纤维为玻璃纤维或者竹纤维，
步骤S1中，增强纤维与树脂浆料混合前经过剪短处理，增强纤维长度控制为3-5mm。
所述透明防护层为树脂层，利用透明的树脂作为防护层，不仅有效保护颗粒状的装饰层，而且其凝聚在颗粒间隙之间，在光照折射效果下增强立体感。
以上显示和描述了本发明的基本原理和主要特征及其优点，本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内，本发明要求保护范围由所附的权利要求书及其等效物界定。
