Embodiment 1

[0043] A carbon fiber high-strength corrugated base paper is made of the following raw materials in weight percentage:

[0044] Waste paper 80%, carbon fiber 4%, starch 7.4%, additives 0.6%, water 8%;

[0045] Wherein, auxiliary agent is rosin, alum, oxidized starch, soda ash, dispersant, non-ionic polymer flocculant, surface sizing agent, bactericide, defoamer, retention aid, and the weight ratio of above is (40 -120):(100-350):(100-350):(5-12):(1-4):(0.2-1):(0.2-1):(0.2-1):(0.2-1 ):(0.2-1):(0.2-1).

[0046] The waste paper is AOCC waste paper and LOCC waste paper, and the weight ratio of the two is 3:2. The dispersant is one or both of polyvinyl alcohol and polyacrylamide.

Abstract

The invention discloses a carbon fiber high-strength corrugated raw board and a preparing method of the carbon fiber high-strength corrugated raw board and belongs to the field of paper technology. The carbon fiber high-strength corrugated raw board comprises, by weight, 78%-82% of waste paper, 3%-5% of carbon fibers, 6%-9% of starch, 0.5%-0.8% of assistant and 8%-9% of water. The assistant comprises rosin, alum, oxidized starch, sodium carbonate, a dispersing agent, non-ionic type polymeric flocculant, a surface sizing agent, a sterilizing agent, an antifoaming agent and retention aid. The carbon fiber adding amount of the high-strength corrugated raw board is small, the cost of the corrugated raw board is reduced to a great extent, the mechanical strength is high, the specific resistance is 107 omega cm-104 omega cm, and the electrostatic-resistant function is good. The main component of solid waste generated in the preparing process is fibers, the fibers can be used for preparing fiber boards, the utilization of the waste is achieved, and pollution of the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a carbon fiber high-strength corrugated base paper and a preparation method thereof. Background technique [0002] Carbon fiber is a new type of carbon material with a carbon content of more than 93% obtained through high-temperature carbonization at 1300-1600 °C. Among them, there are many superior properties over plant fibers as follows: high thermal conductivity, small thermal expansion coefficient, small friction coefficient, high electrical conductivity; almost no elastic fatigue; light weight, mechanical strength, elasticity, tensile strength and compression resistance. Relatively good; good acid resistance, can withstand the erosion of concentrated hydrochloric acid, concentrated sulfuric acid, phosphoric acid, etc.; high temperature resistance, can be used at 2000 ° C, and does not soften or melt in an environment of 3000 ° C. It is precisely because carbon fiber has...
