Paper pulp moulded sheet material and making method thereof

Abstract

The present invention discloses a paper pulp moulding sheet material with high compression strength, good toughness and good moisture resistance. Its raw material composition includes waste paper, natural resin, starch and aluminium sulfate according to the mixing ratio of 100:5-10:5-20:1-2 and its production process inctudes the following steps: breaking pulp, mixing pulp, concentrating, moulding-forming, dampness-removing and drying and finishing. Said invented product is non-toxic, smellless, and has no irritation and can be naturally degraded, can be substituted for wood plate and artificial veneer, so that it has extensive application.

Description

Technical field [0001] The invention relates to a board, in particular to a board made of waste paper, and simultaneously the invention also relates to a method for making the board. Background technique [0002] People use materials such as wood, plastic, artificial plywood (such as plywood, particleboard, fiberboard, MDF, etc.) or metal in the fields of packaging, storage and transportation of goods, construction, home decoration, furniture and office equipment. . However, because some of these materials contain toxic chemical substances, some are lack of raw materials, some cannot be degraded naturally or have factors such as destroying the ecological environment, which affect the further application of these materials. In recent years, many scientific and technological personnel and business people are constantly developing some new materials to replace the above-mentioned materials and have made some achievements, such as degradable plastics, but they have not been wid...

However, because some of these materials contain toxic chemical substances, some are lack of raw materials, and some are not naturally degradable or have factors such as destroying the ecological environment, which affect the further application of these materials.

In recent years, many scientific and technological personnel and business people are constantly developing some new materials to replace the above materials and have made some achievements, such as degradable plastics, but they have not been widely used because of their high cost.
