Description

一种汽车备胎盖板的生产工艺
技术领域
本发明涉及一种汽车备胎盖板的生产工艺，具体地说是用于安装在汽车后备箱的备胎槽上，可以用来放置其它物品，属于汽车内饰件技术领域。
背景技术
汽车内饰件一般安装于汽车车身内部，起到美化、防护、以及隔音吸音等作用。在越来越追求高性能、环保型、节能型、轻量化、个性化的时代，汽车的内饰与汽车的性能一样，越来越得到人们的关注了。因此对汽车内饰件的要求也越来越高。在现有技术中，备胎盖板的质量轻、价格高、气味和VOC等性能指标制约着备胎盖板的发展。现有备胎盖板多数采用PP蜂窝板冲切成型，喷胶贴合面料，其缺点是：表面柔软、需要支撑性板材较多和气味、VOC无法达标等（不能满足某些汽车对备胎盖板的高性能要求）。
发明内容
本发明的目的在于克服上述不足之处，提供一种汽车备胎盖板的生产工艺，其重量轻，节省材料，气味和VOC性能好，更加环保。
按照本发明提供的技术方案，一种汽车备胎盖板的生产工艺，步骤为：
（1）基材烘温处理：将PU复合板材放入烘箱中，设置烘箱中温度240-370℃，烘温时间45-60s，保证出箱时温度为190-200℃；
（2）压制成型：将步骤（1）所得烘温后的PU复合板材放置在模具中，面毯有胶的一面覆盖在PU复合板材上，18-22MPa成型带冲切得到半成品；保压时间为保压45-55s；
（3）附件组立：取出步骤（2）所得半成品，安装减震垫和缓冲垫附件。
（4）检验：经检验后，装箱入库，即得产品汽车备胎盖板。
所述PU复合板材自上至下依次为上表皮层、基材半硬质聚氨酯PU、下表皮层和底布。所述上表皮层和下表皮层均为改性热熔胶膜层或无碱玻纤层。所述半硬质聚氨酯PU密度为40kg/m3。所述底布为不织布PET。
步骤（4）要求产品表面无破损、色差、污点，产品无变形。
步骤（2）所述面料为PET无纺布面毯。
本发明的有益效果：本发明采用PU基材代替了PP木粉板、PP蜂窝板，使汽车备胎盖板的气味和VOC等性能能够满足性能指标，减少了支撑性板材的用量，降低重量，节约耗材，减少成本。
