Abstract

The invention discloses an easily degradable mineral fiber-filled foam stone corrugated paper core and a preparation method thereof, and is characterized in that the paper core is prepared from the following raw materials in parts by weight: 1-2 parts of chitosan, 15-20 parts of calcium carbonate, 1-2 parts of starch, 16-19 parts of diatomite, 15-20 parts of wollastonite, 30-40 parts of polyethylene, 0.5-1 part of azodicarbonamide, 1-2 parts of glyceryl stearate, 55-65 parts of a rosin alcohol solution, 30-40 parts of a polytetrafluoroethylene emulsion, 3-5 parts of Mg(OH)2, 5-10 parts of a polyacrylate emulsion, 30-40 parts of dilute sulfuric acid, 1-2 parts of sodium dodecyl sulfate, and 5-10 parts of ethanol. The prepared stone corrugated paper core has the characteristics of uniform and fine pores and light weight, improves waterproof and flame retardant properties, and moisture-proof and antibacterial properties, and can be better applied to the packaging field; with cooperation of the added chitosan, the prepared corrugated paper core has the characteristic of easy degradation.

Description

technical field [0001] The invention relates to the field of stone paper, in particular to an easily degradable mineral fiber-filled foam stone corrugated paper core and a preparation method thereof. technical background [0002] Corrugated paper, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of cardboard paper. It has good elasticity and extensibility. It is mainly used to make cartons, the sandwich of cartons, and other packaging materials for fragile goods. Traditional corrugated paper is generally made of native straw pulp and waste paper, which is made of raw cardboard similar to yellow cardboard, and then machined to make it into a corrugated shape, and then glued to the surface of the corrugated paper with sodium silicate and other adhesives. become. With the increasing awareness of global low-carbon environmental protection, people are more and more devoted to the research and development of green environmental...
