Abstract

The invention discloses a flame retardant for paper and a method for preparing a piece of flame retardant paper. The flame retardant comprises the following components in parts by weight: 50-80 parts of cationic polyacrylamide, 20-80 parts of cationic starch, 10-13 parts of zinc borate, 40-60 parts of melamine salt of pentaerythritolphosphate, 10-20 parts of pyrophosphoric acid melamine polyvinyl alcohol, 20-60 parts of gelatin, 40-50 parts of carboxy styrene-butadiene latex, 10-20 parts of acrylic acid latex, and 50-60 parts of alginate. The paper prepared by the flame retardant has smooth surface and good flame resistance.

Description

technical field [0001] The invention relates to a paper flame retardant and a method for preparing flame retardant paper, belonging to the field of flame retardant paper. Background technique [0002] Paper is essential in everyday life, and paper is often flammable and poses a hazard. [0003] The patent application with the application number 201410310589.5 discloses an environmentally friendly flame-retardant paper and its preparation method and application. The preparation method includes the following steps: disintegrate the plant fiber raw materials under the conditions of different pulp concentrations; and make the beating degree of the pulp Control at 40-50°SR; then add different proportions of flame retardants, reinforcing agents, retention aids and waterproofing agents to the slurry in sequence, and mix evenly; then make the pulp into paper with a certain amount on the paper machine, Then apply paint on the dried paper by surface sizing, and finally dry it under h...
