Abstract

The invention discloses a high-grade environment-friendly super-sense paper. According to the high-grade environment-friendly super-sense paper, the loose depth is 1.2-1.35g / cm<3>; the horizontal folding strength is greater than or equal to 25 times; the ink absorptivity is 25%-40%; the dry picking strength is greater than or equal to 45 times; and the glossiness is smaller than or equal to 12%. The invention further discloses a preparation process of the high-grade environment-friendly super-sense paper. The process comprises the following steps: preparing a surface sizing liquid; preparing packing; pulping; mixing; beating; sizing; and coating. The preparation process has the advantages of simple technological process and small fiber loss; the prepared high-grade environment-friendly super-sense paper has the characteristics of high paper strength, good surface property, relatively good sheet formability, few paper coating marks, natural paper texture, large loose depth, high folding resistance, low glossiness and the like; and the printed matter is soft in texture, bright in color, high in expressive force of printed images, and outstanding in authenticity and third dimension of images.
