Decorative gypsum board capable of adjusting humidity and removing formaldehyde and production process of decorative gypsum board
The invention provides a decorative gypsum board capable of adjusting humidity and removing formaldehyde and production process of the decorative gypsum board. A gypsum substrate is prepared from the following components: desulfurized gypsum powder, a formaldehyde remover, triethanolamine borate, imported calcium lignosulphonate, a physical foaming agent and water; an environment-friendly water-based coating layer comprises a environment-friendly water-based paint, and 1-5% of modified zeolite is added into the environment-friendly water-based paint; the production process comprises the following steps: mechanically stirring predetermined weight parts of formaldehyde remover, desulfurized gypsum powder, triethanolamine borate and imported calcium lignosulphonate to obtain uniform solid powder; adding a predetermined weight part of physical foaming agent into water, foaming a mixed solution through a foaming system, and feeding the foamed mixed solution into a stirrer; adding the uniform solid powder into the stirrer, fully stirring all the raw materials through the stirrer to prepare a uniform slurry, and subjecting the slurry to extrusion forming, solidification, cutting and drying to prepare the gypsum substrate; subjecting the surface of the gypsum substrate to dust removal treatment, roller painting of the environment-friendly water-based paint, and drying to obtain the decorative gypsum board capable of adjusting humidity and removing formaldehyde.
本发明提供了一种调湿去甲醛装饰石膏板及其生产工艺，石膏基板包括以下组分：脱硫石膏粉、甲醛去除剂、三乙醇胺硼酸盐、进口木质素磺酸钙、物理发泡剂和水；环保水性涂层包含环保水性涂料，环保水性涂料添加有1‑5％的改性沸石；将预定重量份的甲醛去除剂、脱硫石膏粉、三乙醇胺硼酸盐、进口木质素磺酸钙，机械搅拌，得到均匀固体粉末；将预定重量份的物理发泡剂加入到水中，混合液通过发泡系统发泡后进入搅拌机；均匀固体粉末加入到所述搅拌机，各原料经搅拌机充分搅拌制得均匀浆料，浆料经挤压成型、凝固、切断、干燥后制得石膏基板；将石膏基板表面除尘处理，辊涂环保水性涂料，烘干，制得调湿去甲醛装饰石膏板。
