Problems solved by technology

[0003] At present, the adhesive for corrugated cardboard usually uses starch as raw material. Starch adhesive has a wide range of sources, is non-toxic, non-polluting, and low in cost, but is greatly affected by temperature and composition, and its performance is unstable.
The use environment of corrugated cardboard is changeable. When corrugated cardboard is used for a certain period and needs to be recycled, it is often necessary to heat and melt the adhesive. The organic solvents and chemical substances contained in it will cause serious environmental pollution after being discharged.

Abstract

The invention discloses degradable corrugated paperboard glue and a preparation process thereof and relates to the technical field of corrugated paperboard glue. The corrugated paperboard glue comprises the following raw materials in parts by weight: 40-60 parts of corn starch, 10-20 parts of polyvinyl alcohol resin, 5-15 parts of ethyl alcohol, 0.2-0.6 part of caustic soda flakes, 1-4 parts of polyethylene glycol, 0.2-0.6 part of defoaming agent, 0.1-0.5 part of stabilizer, 0.02-0.08 part of plasticizer, 0.05-0.3 part of borax, 0.002-0.008 part of titanium tetrabutoxide, 0.005-0.01 part of triphenyl phosphate and 80-150 parts of water; and the preparation process comprises the steps: degrading the polyvinyl alcohol resin; and mixing the materials. The corrugated paperboard glue disclosedby the invention is high in curing speed, bonding strength and degradation rate and incapable of generating environment pollution.

Description

Technical field: [0001] The invention relates to the technical field of corrugated cardboard glue, in particular to a degradable corrugated cardboard glue and a preparation process thereof. Background technique: [0002] Corrugated cardboard, 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. [0003] At present, adhesives for corrugated cardboard usually use starch as raw material. Starch adhesives have a wide range of sources, are non-toxic, non-polluting, and low in cost, but are greatly affected by temperature and composition, and their performance is unstable. The use environment of corrugated cardboard is changeable. When corrugated cardboard is used for a certain period and needs to be recycled, it is often necessary to heat and melt the adhesive.
