Description
技术领域
本发明涉及橡塑管制品领域，特别涉及采用硫化技术和风冷系统的彩色橡塑管制品制备工艺。
背景技术
彩色大直径多用于暖通管道保温。有闭孔柔性结构可抗渗透、导热系数较低等优点，管道内介质种类各异，彩色橡塑美观且可以区分不同管道的功能，目前市面上尚无此种制品，多用橡塑保温板替代，但保温板在裁剪、弯曲和涂胶后包裹性较差，贴合度不高，且限制了施工速度和浪费材料，胶水也存在不环保等危害。现有的技术存在以下缺点：
1、市面尚无此种彩色大直径橡塑制品；
2、大直径橡塑由于工艺限制较难以制备，且加入颜料后易收缩、龟裂，发泡不均匀且闭孔率不高等缺点；
3、常规冷却水槽长度有限，冷却不彻底导致彩色橡塑管内部结构不够稳定，抗水汽渗透能力差、抗撕裂强度低等缺点。
发明内容
本发明的目的在于提供一种满足暖通要求的新型大直径彩色橡塑制品，以解决用新材料，稳定泡孔结构，使其不出现收缩和龟裂，启用新型硫化工艺，发泡后材料均匀，闭孔率达到要求，改善冷却工艺。
