Abstract

The invention discloses stone paper. The stone paper comprises raw materials of sepiolite fabrics and softwood pulp plates, wherein the average particle size of the sepiolite fabrics is of 80-100 mesh grade; based on oven dry stock, the sepiolite fabrics account for 70-90% and the softwood pulp plates account for 10-30%. A preparation method for the stone paper comprises: firstly preparing a dry strength agent into a solution with the mass concentration of 3-5%; then putting the softwood pulp plates and water in a beating machine to beat; then adding the sepiolite fabrics and mechanically and uniformly stirring the mixture; screening and purifying paper materials by virtue of a vortex scummer; after purification, separately adding the dry strength agent solution, a wet strength agent and a nano enhancer, and uniformly stirring the mixture to obtain the paper pulp; adding a retention aid into the paper pulp; then draining water of the paper pulp on a silk screen to form a wet paper web; feeding the wet paper web which is dehydrated by a squeezing part into a drying part to be dried; then calendering the wet paper web by a calendering machine; and finally obtaining a finished product stone paper. The stone paper disclosed by the invention has excellent ink absorption and flame retardance, and the physical character is further superior to that of wood pulp paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a stone paper and a preparation method thereof. The stone paper is mainly used in cultural paper, wrapping paper, building decoration paper, and special paper with waterproof, oil-proof and rust-proof functions etc. Background technique [0002] The main raw material of traditional paper is plant fiber such as wood. Its production is roughly divided into two basic processes: pulping and papermaking. The pulping process is to dissociate the raw material into natural pulp or bleached pulp. , after various processing to make qualified paper. At present, with the implementation of the national forest protection policy, raw wood is increasingly scarce, and papermaking raw materials mainly rely on imported wood pulp. At the same time, due to the need for cooking and bleaching of plant fibers in the traditional paper production process, a large amount of waste water is...
