Anti-aging mineral fiber filled foaming stone corrugated paper core and preparation method thereof

Abstract

The invention discloses an anti-aging mineral fiber filled foaming stone corrugated paper core and a preparation method thereof. The anti-aging mineral fiber filled foaming stone corrugated paper core is characterized by being prepared from, by weight, 15-20 parts of calcium carbonate, 1-2 parts of nano titanium dioxide, 15-20 parts of diatomite, 1-2 parts of antioxidant DNP, 15-20 parts of wollastonite, 30-40 parts of polyethylene, 0.5-1 part of azobisformamide, 1-2 parts of glutinous rice powder, 50-60 parts of rosin alcohol solution, 30-40 parts of polytetrafluoroethylene emulsion, 3-5 parts of Mg(OH)2, 5-10 parts of polyacrylate emulsion, 30-40 parts of dilute sulphuric acid, 1-2 parts of sodium dodecyl sulfate and 5-10 parts of ethanol. The prepared stone corrugated paper core has the advantages of being provided with uniform and fine pores and being light in mass, improves the waterproof, flame-retardant, moisture-proof and antimicrobial properties of the paper core, can be better applied to the field of packaging. The matched antioxidant is added to a coating, and the anti-aging properties of corrugated paper are improved.

Description

technical field [0001] The invention relates to the field of stone paper, in particular to an anti-aging 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 protec...

Problems solved by technology

[0003] In "Preparation and Performance Testing of Foamed Stone Paper", Gao Gao used calcium carbonate, polyethylene and azodicarbonamide to prepare a foamed stone paper through high-speed cold mixing, melt mixing and other processes, but this stone paper When used as packaging, there are still disadvantages of poor waterproof and flame retardant performance, poor elasticity and flexibility
