Description

1. Technical field

[0001] The invention relates to papermaking technology, in particular to a flame-retardant and fireproof paper containing expandable graphite and a manufacturing method thereof. 2. Background technology

[0002] A typical composition of existing flame retardant materials, which mainly includes: expandable graphite (a), phosphorus-containing plasticizer (b), inorganic phosphide (c); wherein, expandable graphite, phosphorus-containing plasticizer and inorganic The mixing weight ratio of phosphide is 03. to 0.5:0.3 to 1.5:1.

[0003] Another existing flame retardant material composition is used to add to a carrier substrate (such as paint, viscose, foam, fabric, rubber or plastic) to make it have a fireproof and flame retardant effect; the flame retardant combination The material mainly includes: 10 to 70 parts of expandable graphite, 15 to 110 parts of carbon layer forming agent and 90 to 110 parts of carbon layer catalyst; when heated and catalyzed by the ...

Embodiment Construction

[0028] The present invention is a kind of flame-retardant fire-proof paper containing expansive graphite and its manufacturing method. Regarding the composition of fire-proof paper, it includes: (a) expansive graphite with a weight percentage of 20% to 80% and evenly distributed, the expansive Graphite will expand when it encounters the fire port, and has sufficient flame resistance to block the transfer of the fire port; (b) the rest is evenly distributed pulp containing paper-making fibers.

[0029] More specifically, the fiber for papermaking includes a natural fiber for papermaking, and the natural fiber for papermaking is selected from one or more of wood pulp, hemp pulp, and cotton pulp. In addition, the fiber for papermaking includes a chemical fiber for papermaking, the chemical fiber for papermaking is selected from high melting point polyester fiber (refers to high melting point PET fiber, the PET is the abbreviation of Polyethylene terephthalate), low melting point p...
