example 1

[0024]In parts by weight, 20 parts of aluminum chloride hexahydrate and 10 parts of magnesium chloride hexahydrate are dissolved in 80 parts of deionized water to obtain a salt solution, and 30 parts of sodium hydroxide and 30 parts of sodium carbonate are dissolved in 90 parts of deionized water , to obtain the alkali solution, seal the alkali solution and the salt solution respectively and put them into an ultrasonic cleaning machine for ultrasonic treatment for 15 minutes, and control the power of the ultrasonic cleaning machine to 180W; under the protection of nitrogen, 300mL of the salt solution and 200mL of the alkali solution were dripped at the same rate. Add it into the mist-making reactor, control the dropping rate to 8mL / min, and the pH of the reactor system is 10. After the dropwise addition, start the high-speed agitator and stir the reaction at a speed of 2000r / min for 30min to obtain a reaction slurry; Transfer the reaction slurry to a water bath, heat up to 90°C...

Abstract

The invention relates to the technical field of preparation of flame retardant paper, and concretely relates to a preparation method of a piece of flame retardant paper with high durability. Magnesium-aluminium hydrotalcite is prepared, and twice filtering, paper making, and drying are carried out in order to obtain a piece of flame retardant paper with high durability; paper pulp fiber is treated, a two-layer membrane structure is formed on the surface, electrostatic absorption is enhanced between magnesium-aluminium hydrotalcite positive charges and paper pulp fiber negative charges, adhesive attraction of magnesium-aluminium hydrotalcite in the paper pulp fiber is improved, retention of magnesium-aluminium hydrotalcite is improved, flame retardation effects of the flame retardant paperis lasting, polyacrylamide can substantially increase steric hindrance of the paper, the surface of magnesium-aluminium hydrotalcite has positive electricity, organic polymer polyacrylamide has negative electricity, magnesium-aluminium hydrotalcite is uniformly dispersed in the paper pulp fiber, paper pulp fiber has enhanced physical anchoring effects in magnesium-aluminium hydrotalcite apertures,retention of magnesium-aluminium hydrotalcite which plays flame retardation effects in the flame retardant paper is improved, flame retardation and durability performance are improved, and the application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of preparation of flame-retardant paper materials, in particular to a preparation method of high-durability flame-retardant paper. Background technique [0002] Paper and paper products are the most common items in human's daily life. They are generally made of plant fibers and are flammable substances. The flammability of plant fibers determines the flammability of paper products. Due to its flammability, it often causes fires. In order to eliminate fire hazards, the research on the flame retardant properties of paper products is also increasing day by day, and the research on flame retardant paper has also received people's attention. [0003] Flame retardant paper is made by adding flame retardants to the inside of paper or coating on the surface of paper through processing techniques such as pulp addition, impregnation and coating. Flame retardants achieve the purpose of flame retardancy by hindering ...
