Flame-retardant corrugated paper and production methods
Existing crepe paper (colour crepe paper), is to use crepe paper base paper, through the dyeing liquid, the wrinkling, drying processes, this paper do not have flame retardancy, meet fire burns easily, itself being unsafe factors.
The purpose of the present invention is to solve the flame retardancy of corrugated paper.
The technical solution is the corrugated paper of the present invention, which contains water-soluble flame retardant and has the function of carbonizing only in case of fire and producing no flame.
Its production method is to adopt the wrinkle paper, when soaking or dyeing, add the water-soluble flame retardant in the soaking liquid, soak or coating the wrinkle paper, through wrinkling, drying.
The above soaking liquid is all kinds of dyeing liquid.
The above water-soluble flame retardant is ammonium sulfate.
The above water-soluble flame retardants account for 5-15% of the total quality of the soaking solution.
Method 2 is in the process of production lines base paper, slurry mixing will join the rest of the base paper slurry water soluble flame retardants, fully mixing, through manufacture paper with pulp base paper, and wrinkles after dyeing, wrinkles, dry.
The invention of flame retardant crepe paper production method (soaked) due to the dyeing liquid adding water-soluble flame retardants or in paper manufacture paper with pulp before adding water-soluble flame retardant paper slurry process in the big change, method is simple, product besides the function of the average crepe paper, also has the flame retardancy, in case of fire, carbide only halogen-light to produce, increased its fire safety factor.
An optimal embodiment of the present invention is shown in the diagram of the production of flame-retardant corrugated paper.
Choose wrinkles base paper (1) through several tension bridle roll and paper roll, impregnation trough soaking liquid of (2), water soluble flame retardant ammonium sulfate added soaking solution, 5% of the total quality, its content is the soaked fluid under the applicator roll (3) and the applicator roll (5), the coating liquid, overvoltage paper roller (4), through the wrinkling wrinkle scraper (6), the number one cylinder dryer (9), the no. 2 (10) of the dry, with a cutting knife (11), paper cutting, (12) via the paper winding.To enhance the drying effect, blanket (13) through the guide roller (7), the tensioning roller (8) wrap the first dryer (9), wrapping the corrugated paper roll over the first dryer at a uniform speed.
The above - mentioned raw paper can be soaked in soaking liquid, other procedures and the same as above.
The aforesaid soaking liquid can be dyed in red, yellow, blue and other colors, so as to produce red, yellow, blue and other corresponding colors of flame-retardant wrinkle paper.
The above water soluble flame retardant ammonium sulphate accounts for 10% and 15% of the total quality of the soaking liquid.
The present invention can also be in the process of wrinkles base paper production, manufacture paper with pulp slurry mixing before, will join the rest of the base paper slurry water soluble flame retardants, fully mixing, the manufacture paper with pulp was wrinkled base paper, again through the other processes.
