Abstract

The invention discloses a high stability type paper tuber adhesive and belongs to the technical field of adhesives. Polyvinyl alcohol molecule is used as a main chain, is combined with subsequent prepared composite reinforcement three-dimensional crosslinked network, and provides better pressure resistance. An esterification acylation product is prepared and combined with an organic polymer, and the esterification acylation product can well relieve external shocks and guarantee creep resistance of the pressure resistant composite material. A hyperbranched polymer is formed by carboxyl termination, so that a large number of branched structures are contained in a molecular structure, and high fluidity and better solubility are provided. By use of branched molecular chains, entanglement is performed on components so as to improve compactness of the paper tuber adhesive, and viscoelasticity can be well kept when the paper tuber adhesive is under external shocks. The prepared hyperbranchedcomponents are further combined to perform filling and dispersing on the inner part, so that an anti-impact property is improved, and pressure and creep resistance is guaranteed. The adhesive solves the problem that the current common paper tuber adhesives have poor compression strength and creep resistance after use.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a high-stable paper tube adhesive. Background technique [0002] Paper tubes have good development and application prospects, and can be used as substitutes for metal, glass, and ceramic packaging containers. Compared with these packaging containers, paper tube packaging has obvious advantages. Its main features are: the paper tube is made of paper as the main raw material, and it is easy to recycle; it is odorless, non-toxic, safe and reliable, especially suitable for food packaging; it can be filled with various Various shapes of goods, and low noise when filling; various shapes and structures, the outer layer can be color-printed, with good display effect; light weight, easy circulation, convenient use, and low price. Paper tubes are widely used in chemical fiber industry, film industry, printing industry, papermaking industry, metallurgical industry, packaging, temperature...
