Abstract

The invention discloses flame-retardant fireproof paper. The flame-retardant fireproof paper comprises the following components by mass percent: 1 to 10 percent of a flame-retardant agent, 1 to 10 percent of a retention aid, 80 to 98 percent of paper pulp, and totaled in 100 percent. The invention also discloses a preparation method of the flame-retardant fireproof paper. The preparation method comprises the following steps: (1) preparing the flame-retardant agent; (2) preparing the retention aid; (3) preparing the paper pulp; and (4) mixing the flame-retardant agent, the retention aid and thepaper pulp, wherein the content of the components is as follows: 1 to 10 percent of flame-retardant agent, 1 to 10 percent of retention aid, and 80 to 98 percent of paper pulp, totaled in 100 percent; heating and stirring for 30 to 90 minutes, performing thermal insulation for 30 to 90 minutes at the temperature of 40 to 90 DEG C, and forming a mixed material A; and (5) preparing paper. The flame-retardant fireproof paper provided by the invention is convenient and simple in production and preparation process, good in fireproof and heat insulation function, low in cost, high in fire resistance, easy in degradation, energy-saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of fireproof paper, and relates to a fireproof fireproof paper, and also relates to a preparation method of the fireproof fireproof paper. Background technique [0002] The occurrence of fire will lead to the occurrence of phenomena such as life and property safety, environmental pollution and destruction of social public facilities. Therefore, relevant units have stricter regulations on fire protection, more and more attention has been paid to the selection of fire protection materials, and fire protection materials have become more and more popular. [0003] The flame retardants of most fireproof papers on the market are mostly aluminum foil, ammonium polyphosphate and other phosphates, and fireproof silicone rubber. The cost of these materials is relatively high and they are not environmentally friendly. The heat insulation function is poor, and the performance of fireproof paper is not good. As the say...
