The invention provides an environment-friendly gypsum board protective paper and a production method thereof, belonging to the technical field of paper making. The environmental protection type gypsum board protecting paper is made of surface layer paper and inner layer paper, and is characterized in that the surface layer paper is made of chemical pulp, and the inner layer paper is made of waste paper pulp and fly ash fiber pulp. Method for producing environment-friendly gypsum board paper, which is characterized in that the specific steps are: chemical pulp board by beating ease chemical pulp, and then by the Internet and making the paper surface layer obtained by breaking the waste paper; and after washing, beating by waste paper pulp, fly ash fiber fluffer with fly ash fiber pulp, waste pulp and fly ash fiber pulp mixing, through the Internet and get in the paper making layer; the surface layer in the layer of paper and paper surface sizing press after drying, drying again, and finally get to the pressure of light volume gypsum board protective paper. The invention has the advantages of low cost and good comprehensive performance.
【技术实现步骤摘要】
本专利技术涉及,属于造纸
技术介绍
所谓纸面石膏板护面纸就是生产纸面石膏板时,覆盖于石膏芯两面,并能与石膏 芯材牢固地粘合在一起,对石膏芯起到保护作用的那两层纸板。采用纸面石膏板做成的隔 墙具有质轻、隔音、防火、易装饰等特点,对建筑特别是高层建筑是一种必不可少的新型建 筑材料。 现有的纸面石膏板护面纸的缺点是成本高,且防腐性、防蛀性、阻燃性、电绝缘、透 气性、耐温性等有待提高。
技术实现思路
本专利技术的目的是提供,其能够克服上 述缺点,所得纸面石膏板护面纸成本低且综合性能较高。 本专利技术的技术方案是提供一种环保型纸面石膏板护面纸,由面层纸幅和里层纸幅 制成,其特征在于,面层纸幅由化学浆制成,里层纸幅由废纸浆和粉煤灰纤维浆制成,所述化学浆、废纸浆以及粉煤灰纤维浆的绝干重量比为10-20 : 40-70 : io-so。 进一步地,所述的化学浆为漂白硫酸盐针叶木浆。 本专利技术还提供了上述环保型纸面石膏板护面纸的生产方法,其特征在于,具体步 骤为 第一步将打浆度为15° SR的化学浆板再次打浆疏解,打浆后重量浓度为3X,打 浆度为24 30° SR,打浆 ...
