Abstract
The invention discloses a kind of environment-friendly type starch glue formula and its preparation technology.This environment-friendly type starch glue is by raw materials such as polyvinyl alcohol, hydrochloric acid, starch, polyacrylamide, surfactant, preservatives, through being gelatinized, being acidified, the chemical reaction such as being grafted and be made.The environment-friendly type starch glue that the invention provides has the features such as bulk paste, tack are good, and bonding force is strong, water-tolerant, is used especially suitable for the paper products such as paper, carton, cardboard bonding or bound edge.
Description
Technical field
The present invention relates to adhesive technical field, more particularly to one kind can be used for paper products bonding particularly paper package box
The environment-friendly type starch base adhesive of bonding.
Background technology
It is cheap because starch source enriches, so the paper product industries such as amylan is honeycomb cardboard, corrugated board institute
Pro-gaze, but the problems such as inadequate adhesive strength, failure of poor water resistance, mutability also be present in amylan.
During paper products post-processing, particularly honeycomb cardboard industry, downstream equipment deficiency, manually grasp substantially
Make, because paper is particularly easy to absorb water, after amylan is brushed to above paper, is not in time for bonding also with regard to substantially dry, loses
Adhesive property, so to develop, a kind of moderate drying speed, tack are strong, bonding is firm, the environment-friendly type starch glue of water-tolerant
Have great importance.
The content of the invention
Technical problem solved by the invention is to provide a kind of environment-friendly type starch adhesive, this adhesive rate of drying
Slowly, bonding force is strong, water resistance is good, and preparation technology is simple, cost of manufacture is cheap, can be used to solve lacking in above-mentioned background technology
Point.
Technical problem solved by the invention is realized using following technical scheme：
A kind of environment-friendly type starch adhesive, its component and mass fraction are as follows：
5 ~ 20 parts of starch
2 ~ 10 parts of polyvinyl alcohol
0.2 ~ 1 part of hydrochloric acid
0.1 ~ 1 part of sodium hydroxide
0.01 ~ 0.1 part of surfactant
0.05 ~ 1 part of polyacrylamide
50 ~ 80 parts of water
0.1 ~ 0.3 part of preservative
The preparation technology of above-mentioned environment-friendly type starch adhesive is：
1) polyvinyl alcohol is placed in reactor, adds water, hydrochloric acid is added dropwise, adjust pH=1 ~ 3, added surfactant, add
Heat carries out circulation stirring with 60 ~ 80r/min rotating speed in a reservoir to 90 DEG C, and mixing time is completely dissolved by material and is defined.
2) by 1/4 ~ 3/4 difference of starch and whole polyacrylamide amounts it is soluble in water after, be added into reactor, protect
90 DEG C of kettle temperature is held, and with 60 ~ 80r/min 30 ~ 120min of rotating speed stirring reaction.
3) take sodium hydroxide to neutralize, its pH is modulated into 5-7.
4) remaining polyacrylamide is added, 10min is stirred with 60 ~ 80r/min rotating speed, is cooled to 40 DEG C of dischargings.
In the present invention, the hydrochloric acid use concentration for 36% ~ 38% concentrated hydrochloric acid.
In the present invention, the surfactant is sodium alkyl sulfate class, sodium alkyl benzene sulfonate class, sodium pyrophosphate, alkyl
Polyethenoxy ether sodium sulfate, Alkyl ethoxy carboxylate acid sodium, sodium alkyl sulfonate, fatty alcohol sulphuric acid（Ester）One kind in salt etc. or
Two kinds of mixtures.
In the present invention, the preservative is one kind in KF88, benzoic acid and its esters, parabens, and it is added
Before time is any whipping process.
Advantages of the present invention and beneficial effect are：
The environment-friendly type starch adhesive of the present invention, is not added dropwise the noxious materials such as formaldehyde, belongs to nontoxic, free of contamination gluing
Agent
1. the environment-friendly type starch adhesive of the present invention, due to the addition of surfactant, can prevent protein aggregation, prevent
The generation of starch gelling phenomenon, extend the Storage period of glue.
2. the environment-friendly type starch adhesive of the present invention, polyacrylamide is first added as grafted monomers, can increase amylan
The pliability of film, polyacrylamide is finally added as thickener, can improve the outward appearance of glue and increase the tack of glue, in addition
It may be such that the rate of drying of glue is reasonably controlled.
3. the environment-friendly type starch adhesive of the present invention, product appearance is the bulk paste of white, suitable manual brush coating, avoids glue
Imprudence drop on the ground, pollutes working environment, and reduce the waste of glue.
4. the environment-friendly type starch adhesive of the present invention, low to device requirement, technique is simple, is adapted to medium-sized and small enterprises to use.
