Flame-resistant fireproof paper containing expansion graphite and producing method thereof

Abstract

The present invention provides one kind of fireproof paper containing expansion graphite and its making process. The fireproof paper contains expansion graphite in 20-80 wt% except paper fiber. The fireproof paper making process includes the steps of: preparing material, preparing paper pulp, mixing, making paper sheet and processing. The fireproof paper has excellent fireproof performance, wide application range, simple making process and ideal use effect.

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 ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned flame retardant materials have been applied to coatings, viscose, foam, fabrics, rubber or plastic products, there is currently no technology on the market for paper products. Therefore, it is necessary to research and develop new technologies to enable Paper products are difficult to burn and fireproof, thus benefiting the society and the general public
