摘要
A method for manufacturing a wastepaper shock absorbing material using a vacuum forming principle is provided. The method includes disintegrating wastepaper selected from at least one of old corrugated containers, old newspapers and milk cartons, diluting the disintegrated wastepaper to form a pulp suspension, mixing the pulp suspension with a cationic starch to form a mixture, and vacuuming the mixture by applying a first vacuum in a first direction and a second vacuum in a second direction in a vacuum former to vacuum-dehydrate the mixture and provide a shock absorbing material. The first direction is substantially opposite to the second direction. The method further includes drying the shock absorbing material and performing a surface sizing process on a surface of the shock absorbing material. The wastepaper shock absorbing material has a low elastic modulus and density and can be manufactured without using the conventional press process performed by a press plate.
