Abstract
The invention discloses an environment-friendly starch adhesive and a preparation process thereof. The environment-friendly starch adhesive is prepared by taking polyvinyl alcohol, a hydrochloric acid, starch, polyacrylamide, a surfactant, a preservative and the like as raw materials through the chemical reactions such as pasting, acidifying, grafting, and the like. The environment-friendly starch adhesive provided by the invention has the characteristics of bulking paste, good initial adhesivity, strong adhesive strength, good water resistance, and the like, therefore, the environment-friendly starch adhesive is especially applicable to the adhering or edge covering of paper products such as paper, carton boxes, paperboards and the like.
Description
Technical field
The present invention relates to sizing agent technical field, particularly relate to and a kind ofly can be used for the bonding environment-friendly type starch base adhesive of the bonding particularly paper package box of paper product.
Background technology
Because starch source enriches, cheap, so amylan is looked at for the paper product industries such as honeycomb cardboard, corrugated cardboard institute parent, but amylan also exist bonding strength not, poor water resistance, the problem such as volatility inefficacy.
In paper product post-treatment process, particularly honeycomb cardboard industry, downstream equipment is not enough, basic by manual operation, because paper especially easily absorbs water, be brushed to after above paper at amylan, be not also able to do in time bonding with regard to substantially dry, lose adhesive property, so will develop, a kind of moderate drying speed, tack are strong, bonding firmly, the environment-friendly type starch glue of water-tolerant has great importance.
Summary of the invention
Technical problem solved by the invention is to provide a kind of environment-friendly type starch sizing agent, and this sizing agent rate of drying is slow, bonding force is strong, water tolerance is good, and preparation technology is simple, cost of manufacture is cheap, can in order to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of environment-friendly type starch sizing agent, its component and mass fraction as follows:
Starch 5 ~ 20 parts
Polyvinyl alcohol 2 ~ 10 parts
Hydrochloric acid 0.2 ~ 1 part
0.1 ~ 1 part, sodium hydroxide
0.01 ~ 0.1 part, tensio-active agent
Polyacrylamide 0.05 ~ 1 part
50 ~ 80 parts, water
Sanitas 0.1 ~ 0.3 part
The preparation technology of above-mentioned environment-friendly type starch sizing agent is:
1) polyvinyl alcohol is placed in reactor, adds water, drip hydrochloric acid, regulate pH=1 ~ 3, add tensio-active agent, be heated to 90 DEG C, and carry out circulation stirring with the rotating speed of 60 ~ 80r/min in a reservoir, churning time is dissolved completely with material and is as the criterion.
2) by starch and all polyacrylamide amount 1/4 ~ 3/4 soluble in water respectively after, be added in reactor, keep the still temperature of 90 DEG C, and with the rotating speed stirring reaction 30 ~ 120min of 60 ~ 80r/min.
3) get sodium hydroxide neutralization, its pH is modulated 5-7.
4) add remaining polyacrylamide, stir 10min with the rotating speed of 60 ~ 80r/min, be cooled to 40 DEG C of dischargings.
In the present invention, described hydrochloric acid adopts concentration to be the concentrated hydrochloric acid of 36% ~ 38%.
In the present invention, described tensio-active agent is one or both mixtures in sodium alkyl sulfate class, sodium alkyl benzene sulfonate class, trisodium phosphate, pareth sulfate, Alkyl ethoxy carboxylate acid sodium, alkyl sodium sulfonate, fatty alcohol sulphuric acid (ester) salt etc.
In the present invention, described sanitas is the one in KF88, phenylformic acid and its esters, parabens, before its joining day is arbitrary whipping process.
Advantage of the present invention and beneficial effect are:
Environment-friendly type starch sizing agent of the present invention, does not drip the toxic substances such as formaldehyde, belongs to nontoxic, free of contamination sizing agent
1. environment-friendly type starch sizing agent of the present invention, owing to the addition of tensio-active agent, can stop protein aggregation, prevent the generation of amylan coagulation phenomena, extends the shelf lives of glue.
2. environment-friendly type starch sizing agent of the present invention, first add polyacrylamide as grafted monomer, the snappiness of Starch Adhesive Film can be increased, finally add polyacrylamide as thickening material, the outward appearance of glue can be improved and increase the tack of glue, the rate of drying of glue can be made in addition reasonably to be controlled.
3. environment-friendly type starch sizing agent of the present invention, product appearance is white bulk paste, and suitable manual brush coating, avoids glue to drip because of carelessness on the ground, pollutes Working environment, and reduces the waste of glue.
4. environment-friendly type starch sizing agent of the present invention, low to device requirement, and technique is simple, is applicable to medium-sized and small enterprises and uses.
