Fireproof honeycomb paperboard and manufacturing method thereof

Abstract

The invention discloses a fireproof honeycomb paperboard. The fireproof honeycomb paperboard comprises the following components in parts by weight: 30-50 parts of grass rod, 10-30 parts of timber, 50-70 parts of waste paper, 15-35 parts of straw rod, 220-300 parts of water, 8-12 parts of flame retardant, 5-8 parts of starch, 11-15 parts of polyvinyl alcohol, and 4-8 parts of fireproof paint; and the fireproof paint is prepared by the following components in parts by weight: 3-5 parts of flame retardant, 3.5-5.5 parts of polysiloxane, 5-9 parts of urea, 5-7 parts of polyurethane, 4-6 parts of carboxymethylcellulose, 2-4 parts of polyvinyl alcohol, 3-8 parts of aluminum oxide fiber, 12-20 parts of de-ionized water, 7-9 parts of hydroxyethyl cellulose, and 4-8 parts of dispersing agent. A manufacturing method of the fireproof honeycomb paperboard comprises the steps of: (1) pulping; (2) pulp mixing; (3) papermaking; (4) preparation of paperboard raw materials; (5) production of honeycombpaper cores; and (6) formation of honeycomb paperboards; and the manufacturing method relates to the technical field of honeycomb paperboards. The fireproof honeycomb paperboard and the manufacturingmethod thereof solve the problem of flammability of traditional honeycomb paperboards, and achieve the effects of no combustion assistance and prevention of fire spreading.

Description

technical field [0001] The invention relates to the technical field of honeycomb paperboard, in particular to a fireproof honeycomb paperboard and a manufacturing method thereof. Background technique [0002] Honeycomb paper is made according to the principle of honeycomb structure in nature. It connects corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding method to form a whole force-bearing part-paper core, and glues it on both sides. A new sandwich structure environmental protection and energy-saving material made of paper. It is very popular because of its ability to withstand high pressure and its light weight. However, the honeycomb paperboard itself is made of paper, which is flammable and cannot be widely used in many occasions. Some existing fireproof honeycomb paperboards are coated on the surface There are fireproof materials, but the surface of the cardboard is easily damaged during the handling process, and the fireproo...
