Abstract

The invention belongs to the field of biomass foam materials and particularly discloses a paper pulp foam material and a preparation method thereof. The paper pulp foam material is prepared from the following components in parts by weight: 0.5-2.5 parts of paper pulp, 0.005-0.125 part of a surfactant, 0.0005-0.0125 part of cationic polyacrylamide and 97.4-99.5 parts of water. The paper pulp foam material is low in density, high in porosity, green and degradable; the preparation method is abundant in raw material source, simple and feasible in operation, low in cost and environmentally friendly in preparation technology.

Description

technical field [0001] The invention belongs to the field of biomass foam materials, and specifically relates to a pulp foam material and a preparation method thereof. Background technique [0002] Pulp is a product of the paper industry. It is a fibrous substance made from plant fibers through different processing methods. It is a renewable material. Traditional foam (foam) is prepared from petrochemical products, which is not only non-renewable, but also causes environmental pollution because it is non-degradable. Pulp foam is not only rich in raw materials, but also environmentally friendly in the preparation process, and can be degraded, so it has broad application prospects. [0003] At present, domestic related researches include: Chinese patent CN 105885097 A discloses a kind of rigid cross-linked fireproof and thermal insulation nano-cellulose foam; Product; Chinese patent CN 103131038 B discloses a preparation method of lignocellulosic foam material. [0004] Cur...
