Abstract

The invention belongs to the technical field of paper-making methods, and relates in specific to a non-fiber material that is added into paper pulp, in particular to cooperative utilization of paper impregnation materials in paper-making process. The invention relates to a flame retarding and moistproof paper as a paper cellular core material, as well as a relevant preparation method. The preparation method comprises a combined utilization mode of compounds of flame retardant and glutinous agent with high cost performance. Technical indexes of the paper are as follows: Oxygen index (OI): is more than or equal to 32; water content (percent): 6 to 14; quantitation (g / m2): in 50 to 120 or 130 to 450; transversal ring crush compression index (N is multiplied by m2 / g): anticipated as 2.5 to 5 or is more than or equal to 5. The paper-making method is characterized by impregnating flame retarding and fluid of glutinous agent (also named as sizing agent) on raw paper with a papermaking machine or / and a coating machine, and then, by being dried on a drying cylinder on the machine before being reeled and formed in a one-through way.

Description

technical field [0001] The invention belongs to the technical field of paper making methods, and in particular relates to non-fibrous materials added to pulp, especially the combined use of paper impregnating materials in the paper making process. Background technique [0002] The production and application of flame-retardant paper has a long history. With the development of social demand, the technical requirements for flame-retardant paper are getting higher and higher. Other physical properties are poor, such as: moisture resistance, toxicity, non-smoke, paper strength, etc., especially the moisture resistance is not satisfactory; and these types of flame-retardant paper also have the disadvantages of high production costs. [0003] Paper honeycomb core material is a new type of paper product that has been widely used in recent years. It can be used for cargo pallets in the logistics industry, and can also be used as core materials for interior walls and interior doors. I...
