Environment-friendly paper and preparation method thereof

The invention belongs to the technical field of papermaking, and particularly relates to a preparation method of environment-friendly paper. The environmental protection paper is prepared from the following raw materials in percent by weight: 25-35 percent of modified alumina, 40-70 percent of cellulose pulp, 0.5-1.5 percent of wet strength agent, 0.1-0.8 percent of degassing agent, 0.1-0.9 percent of polyacrylamide, 0.5-1.5 percent of dispersant, 0.3-0.8 percent of polyaluminum chloride, 0.4-0.7 percent of glass fiber, 0.5 to 2 percent of formaldehyde urea-formaldehyde resin, 0.1 to 1 percentof white cement, and the balance of water. The environment-friendly paper disclosed by the invention not only has excellent performance in abrasion resistance, surface scratch resistance and surfacedry heat resistance, but also is very low in formaldehyde emission, and can reach the standard of international top environment-friendly products. 本发明属于造纸技术领域，尤其涉及种环保纸的制备方法。所述的环保纸，包含如下重量百分比原料：改性氧化铝25~35%、纤维素纸浆40~70%、湿强剂0.5~1.5
