Abstract

The invention discloses a flame-retardant paper. According to the invention, a flame-retardant liquid is sprayed on a single surface of a raw paper. The flame-retardant liquid is prepared from the raw materials of, by weight: 8-10 parts of aluminum hypophosphite, 8-10 parts of aluminum hydroxide, 8-10 parts of antimony trioxide, 8-10 parts of white carbon black, 3-5 parts of calcium stearate, 1 part of sodium carboxymethyl cellulose, and 100 parts of water. According to the invention, an environment-friendly halogen-free flame-retardant is adopted. The flame-retarding effect is good, and halogenation and moisture absorption phenomena are prevented. The flame-retardant paper has a good flame-retarding effect.

Description

technical field [0001] The invention relates to a kind of flame-retardant paper, which belongs to the field of flame-retardant technology. Background technique [0002] Paper is generally made from plant fibers. The plant fiber is mainly dehydrated glucose (C 6 h 12 o 6 ) is a condensate that is flammable. The flammability of plant fibers determines the flammability of paper products. However, in many cases, paper is required to be flame retardant, such as decorative paper products for home walls, core filling materials, and packaging materials that require flame retardancy. Flame-retardant paper is usually divided into two categories: one refers to paper made of asbestos fibers and does not produce any changes in fire. This kind of paper is also called fireproof paper. The other category refers to adding flame retardant chemicals to pulp or treating plant fibers with flame retardants to obtain flame retardant properties. Although this kind of flame-retardant paper d...
