Abstract

The invention provides high-temperature-resistant composite paper and a preparation method thereof and relates to the technical field of paper product processing. The composite paper comprises four layers from bottom to top, wherein the first layer is a parchment layer, the second layer is an alumina layer, the third layer is a polycarbonate layer, and the fourth layer is a fiber layer formed by mixing polybenzimidazole fiber with polyether sulphone fiber. The prepared high-temperature-resistant composite paper with the four-layer composite structure has good high temperature resistance and mechanical performance, is not prone to damage, has small mass loss rate (less than 1.17%) at the high temperature of 200 DEG C and can still keep higher tensile strength retention rate up to 70% afterworking at 100 DEG C for 6,500 h. The prepared composite paper has good promotion and application value, production of paper for non-traditional machining is further promoted, and import dependence isreduced.

Description

technical field [0001] The invention relates to the technical field of paper product processing, in particular to a high temperature resistant composite paper and a preparation method thereof. Background technique [0002] Paper is an important invention of the working people of the Han nationality in ancient times. The raw materials for papermaking are mainly plant fibers. In addition to the three main components of cellulose, hemicellulose and lignin, there are other components with less content, such as resin, ash, etc., in addition to sodium sulfate, etc. Auxiliary ingredients. Papermaking is one of the "Four Great Inventions" in ancient China. The invention of paper has greatly facilitated the storage and exchange of information, and has epoch-making significance for promoting the development of world civilization. Around the early Western Han Dynasty, people made paper out of hemp and ramie. This early paper was rough and not very suitable for writing. In the East...
