Abstract

The invention discloses ceramic fiber furnish composite paper and a preparation method thereof. The invention aims to provide the ceramic fiber furnish composite paper and the preparation method thereof, which take ceramic fibers and plant fiber dry pulp as main materials, can save forest resources and grass resources and have excellent fire resistance and high strength. The composite paper comprises the main material and an auxiliary material, wherein the main material comprises 25-60% of ceramic fiber and 40-75% of plant fiber dry pulp by weight percentage, the auxiliary material comprises rosin size, and the weight portion percentage of the main material to the auxiliary material is 100:4-8. In the ceramic fiber furnish composite paper, ceramic fibers are utilized to replace the plant fiber pulp so as to save a mass of plant resources, simultaneously, the paper and the cardboard have the performances of anti-corrosion, high strength, fire-resistance, high-temperature resistance, andthe like, and the fire-resistance is excellent; furthermore, the ceramic fiber furnish composite paper has no toxicity or harmfulness and is environment-friendly. The preparation method of the ceramic fiber furnish composite paper reduces the displacement, the wastewater treatment cost, the manufacture cost and the environment pollution.

Description

technical field [0001] The invention relates to ceramic fiber blended composite paper with ceramic fiber and plant fiber dry pulp as main ingredients and a production method. Background technique [0002] At present, the fibers used in paper and paper products used at home and abroad are mainly wood pulp fibers and straw pulp fibers. my country's wood resources are relatively scarce, and traditional papermaking consumes a lot of forest resources and grass resources. Moreover, paper made from plant fibers is easy to corrode, flammable, and easy to absorb moisture. In addition, plant fiber papermaking consumes a lot of water, produces a large amount of black liquor and waste water, seriously pollutes the environment, and waste water treatment increases product costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a ceramic fiber and plant fiber dry pulp as the main material, which can ...
