Abstract

The invention discloses paper pulp of a paper logistics tray. Raw materials of the paper pulp comprise waste corrugated paper, a raw bamboo pulp board, a wood pulp board, auxiliaries and a packing material, wherein the auxiliaries comprises a AKD (Alkyl Ketene Dimer) waterproof agent, a twice-modified polyacrylamide derivative strengthening agent, a PAE (polyarylether) wet strengthening agent, formaldehyde, paranitrophenol, polyacrylamide and polyvinyl alcohol, and the packing material is calcium carbonate; the formula of the paper pulp of the paper logistics tray comprises the following components in percentage by mass: 77% to 80% of waste corrugated paper, 6% to 9% of raw bamboo pulp board, 4 % to 7% of wood pulp board, 1.2% to 2.1 % of AKD waterproof agent, 1.2% to 2.1 % of twice-modified polyacrylamide derivative strengthening agent, 0.8% to 1.5% of PAE wet strengthening agent, 0.6 to 1.2% of formaldehyde, 0.4% to 0.8 % of paranitrophenol, 1.78% to 3.67% of polyacrylamide, 0.12% to 0.28% of polyvinyl alcohol and 4 % to 7 % of calcium carbonate. The formula of the paper pulp of the paper logistics tray has the advantages of low cost, high beating efficiency, high strength of products, good moisture resistance, high permeability and little pollution to environments.

Description

technical field [0001] The invention relates to a kind of pulp, in particular to a kind of pulp of a paper logistics tray. Background technique [0002] With the development of industry, many disadvantages of plastic products, especially expanded polystyrene products, are becoming more and more serious. It has become a popular choice at home and abroad to use degradable and environmentally friendly packaging materials to eliminate "white pollution" and improve people's living environment. unanimous demand. Products made of pulp are truly environmentally friendly products. It uses natural plant fibers or waste paper as pulp raw materials. There is no pollution in the production process and use process. Pulp molded products are gradually entering the mainstream of commercial activities. They are the current foam plastics products. The best substitute products for products. [0003] The pulp formula of paper logistics tray requires low pulp cost, high beating efficiency, high...
