Embodiment Construction

[0013] A production process of flame-retardant paper, including pulping, beating, pulping, molding, dehydration, drying into paper, adding resin to the pulp to pulp, and then forming on the net, spraying the copied wet paper, and then Carry out dehydration, dry into paper; The spray coating is: spray coating with the flame retardant liquid of 250kg / T paper, the boric acid of 50 Kg / T paper and the ethanol of 45Kg / T paper simultaneously, wherein the fire retardant liquid in the fire retardant liquid The concentration of fuel is 12%. The unit Kg / T refers to the amount of kilograms added for each ton of finished paper produced.

[0014] After the slurry adjustment, the stripping agent and urea are added after refining and desanding.

[0015] The release agent is an organosilicon compound.

[0016] Add 2 kg / T paper stripping agent and 3 kg / T paper urea.

[0017] The flame retardant is phosphoric acid ester or phenolic resin.

[0018] Add 30kg / T paper resin.

[0019] The f...

Abstract

The invention relates to a production technology for flame retardant paper. The production technology comprises the following steps of: repulping, pulping, mixing the pulp, forming, dehydrating, drying to make paper, adding resin into paper pulp to mix the pulp, forming on a net, atomizing and coating made wet paper, dehydrating the paper, and drying the paper to make a finished product. Atomizing and coating are executed by flame retardant liquid of 250 kg / T paper, boric acid of 50 kg / T paper and ethanol of 45 kg / T paper, wherein the concentration of a flame retardant in the flame retardant liquid is 10-15 percent. The technology is flame-retardant and environment-friendly; the paper cannot deform or be wetted; the surface of the paper is flat and smooth; and furthermore, during production, toxic gas cannot be generated.

Description

technical field [0001] The invention relates to a production process of papermaking, in particular to a production process of flame-retardant paper. Background technique [0002] People cannot live without paper, and there are many types of paper. Different types of paper use different raw material formulas and production processes. With the rapid development of my country's economy, the application fields of paper materials are constantly expanding, and the market has higher and higher requirements for the variety and quality of paper. Decorative paper products, packaging of items requiring flame retardancy, etc. When the paper with flame-retardant properties burns in a fire, the flame retardant in the paper can suppress the combustion to the greatest extent. [0003] Compared with foreign countries, the research on flame-retardant paper in my country started relatively late. There are also many flame-retardant papers on the market, but they are all very professional, and...
