Abstract

The invention relates to an adhesive, and belongs to the technical field of adhesive for paper tube. The adhesive for paper tube comprises the following components in parts by weight: 46.3-83.4 parts of water, 5-10 parts of polyvinyl alcohol, 0.1-0.5 part of sodium pyrophosphate, 0.1-0.5 part of sodium hexametaphosphate, 0.1-2 parts of 6% oxalic acid solution, 0.1-5 parts of boric acid, 0.1-0.5 part of potassium permanganate, 1-10 parts of corn starch, 10-25 parts of calcined kaolin and 0.1-0.2 part of preservative. The preparation method comprises the following steps of adding water, polyvinyl alcohol, calcined kaolin, sodium pyrophosphate, sodium hexametaphosphate, boric acid and oxalic acid into a reaction kettle according to the mass proportion, dispersing uniformly, then slowly heating to 92 DEG C, preserving the heat for 1.5h, then adding weighed starch and potassium permanganate; after the starch and the potassium permanganate are all added, dispersing at 85 DEG C; preserving the temperature for 30min, and then cooling to 40 DEG C, adjusting the pH (potential of hydrogen) to be 4-5 by a proper amount of 6% oxalic acid solution, adding weighed preservative, so as to obtain the adhesive product for paper tube.

Description

A kind of paper tube adhesive

Technical field: the present invention relates to a kind of tackiness agent, specifically a kind of paper tube adhesive.

Background technology: at present, packaging paper tube amount increases increasingly, but production level is limited, polyvinyl formal paper tube glue quality commonly used is uneven, the temperature of condensation reaction, potential of hydrogen and time all are difficult to control, and very harmful to human body of formaldehyde in production and the use procedure, although added a certain amount of formaldehyde neutralizing agent, the inevitable residual health that is still endangering paper tube adhesive producers and the operator of paper tube factory, roll out in the next paper tube and also have a small amount of residues of formaldehyde, the health of using human body has been consisted of potential harm.

Summary of the invention: the object of the present invention is to provide a kind of constant product quality, excellent property, paper tube adhesive with low cost, fundamentally solve the residues of formaldehyde of this series products, that the paper tube adhesive of producing with the present invention is produced is simple, with low cost, stable storing, help the packaging industry development of China.Its technology contents is, a kind of paper tube adhesive comprises composition quality part: water 46.3-83.4, polyvinyl alcohol 5-10, trisodium phosphate 0.1-0.5, Sodium hexametaphosphate 99 0.1-0.5,6% oxalic acid solution 0.1-2, boric acid 0.1-5, potassium permanganate 0.1-0.5, W-Gum 1-10, calcined kaolin 10-25, sanitas 0.1-0.2, its preparation method: by quality proportioning weighing water, polyvinyl alcohol, calcined kaolin, trisodium phosphate, Sodium hexametaphosphate 99, boric acid, oxalic acid, joining is uniformly dispersed in the reactor slowly is warmed up to 92 ℃ afterwards, be incubated the starch that adds metering after 1.5 hours, potassium permanganate, all add rear 85 ℃ and disperse insulation 30 minutes, cool to afterwards 40 ℃ of oxalic acid solutions with an amount of 6% and regulate ph to 4-5, namely get the paper tube adhesive finished product after adding the sanitas that measures.

Institute of the present invention water is tap water or phreatic water, and polyvinyl alcohol is PVA26-99, and W-Gum is food grade, and used potassium permanganate is SILVER REAGENT, and other raw materials are technical grade.

The present invention is compared with existing technology its advanced part and is, this paper tube adhesive production process is simple, raw material is easy to get, and is with low cost, and production unit is simple, suitability is strong, it is high that the paper tube of producing with this paper tube adhesive has fast dry bond strength, and the paper tube ultimate compression strength that rolls out is good, zero zero emission, complete substituting import one raw material, the decrease cost.

Embodiment: its preparation method, by quality proportioning weighing water 42.2-68.8, join in the reactor, start dispersed with stirring device 80r/min, add polyvinyl alcohol 5-10, trisodium phosphate 0.3-0.5, Sodium hexametaphosphate 99 0.1-0.2,, boric acid 0.5-4, W-Gum 5-8, calcined kaolin 15-25, disperse also slowly to be warmed up to 92 ℃, be incubated adding W-Gum 5-8 after 1.5 hours, potassium permanganate 0.1-0.5, all add rear 85 ℃ and disperse insulation 30 minutes, cool to afterwards the molten 0.1-1.4 of 40 ℃ of oxalic acid with 6% and regulate ph to 4-5, namely get the paper tube adhesive finished product behind the adding sanitas 0.1-0.2, abovely just consist of the present invention.
