Abstract
The invention relates to a production method for making a high-grade cardboard using brush wood sheet hot grinding pulp to replace OCC (obsolescence corrugated cardboard) pulp. The production method comprises the following steps of pulp preparation: using waste box cardboards to prepare OCC pulp; using ONP (old news paper) to prepare ONP pulp; using brush wood sheets to prepare wood chip pulp, mixing the wood chip pulp, saccharomyces chevalieri and a binder, and culturing; pulp blending: using the ONP pulp as a grey board topcoat layer; mixing the OCC pulp and the wood chip pulp to form a grey board liner layer; mixing the OCC pulp and the wood chip pulp to form a grey board core layer; mixing the OCC pulp and the wood chip pulp to form a grey board bottom layer; paper making: using the approaching pulp to make the paper. Compared with the prior art, the production method has the advantages that the wood chip pulp is cultured by microorganisms, so that the thickness, compactness and stiffness of grey board are improved; the raw material structure of the grey board is optimized, the usage amount of OCC waste paper is reduced, the problem of raw material cost of the grey board is reduced, and the economic benefit is obviously improved.
