Abstract
The invention relates to the technical field of a preparation method of an adhesive, and provides a preparation method of an adhesive used for producing a corrugated board. The preparation method mainly comprises the steps of preparing a body adhesive, preparing a carrier adhesive, and uniformly mixing the body adhesive and the carrier adhesive. The adhesive, prepared by the method, has the advantages of higher bonding strength and hardness, good permeability, excellent waterproof and moisture-proof performances, good stability and quick drying speed, and can be widely applied to the corrugated board.
Description
Technical field
The present invention relates to preparing method's technical field of tackiness agent, be specifically related to the preparation method that corrugated board production sticks with glue agent.
Background technology
At present; Paper pack requirement of products to household electrical appliance, precise electronic electronic product, food and medicine etc. are used is increasingly high; Common Packaging Box, wooden packing, EPS packing are replaced by other wrapped products because quality and class can't satisfy the demand in market gradually.Corrugated Box is widely used in the Industrial products overpack owing to advantages such as cost are low, recyclable, pollution-free.
Because the preparation method is improper, tackiness agent is high humidity in use, and rate of drying is slower, and perviousness is bad; Be used for the corrugated cardboard compound tense, can not in time permeate drying; Cause also need adding in corrugated cardboard facial tissue and the core paper recombination process baking operation and make glue dries bonding, strengthened the production technique of fluting board, increased production cost; With the corrugated cardboard that this glue is composited, the phenomenon of position, corner prying or distortion often appears in the poor quality.
One Chinese patent application number: 201010222280.2 disclose a kind of starch adhesive that is used to produce corrugated cardboard and preparation method thereof, and the process step of its preparation method is: the 1. preparation of starch suspension; 2. add the catalysis siccative; 3. oxidation; 4. gelatinization; 5. crosslinked; 6. modification; 7. froth breaking.Its preparation section is complicated, needs more starting material, and cost is high, and preparation time is long, needs to consume more manpower and materials, and the tackiness agent viscosity that makes is not high.
Summary of the invention
Therefore; To the problems referred to above; The corrugated board production that it is simple, time saving and energy saving that the present invention provides a kind of preparation section sticks with glue the preparation method of agent; The tackiness agent that utilizes this method to make has that higher bonding strength, good penetrability, water-fast humidity resistance are good, good stability, rate of drying are fast, can be widely used on the corrugated cardboard.
For achieving the above object, the present invention realizes through following technical scheme: corrugated board production sticks with glue the preparation method of agent, comprises the steps:
(1) preparation of carrier glue: the clear water that in carrier tank, injects 278 ± 5 weight parts; Be heated to 30 ± 2 ℃, then add the uncooked raw corn flour of 34.2 ± 1 weight parts, the limit edged stirs; Wait to add that to add mass concentration behind the uncooked raw corn flour be 33.3% paste agent 16.2 ± 0.5 weight parts; Then carry out shearing treatment, the shearing treatment time is 460 ± 5s, obtains carrier glue;
(2) preparation of main gel: in the main body jar, inject the clear water of 441 weight parts, be heated to 29 ℃, then add the uncooked raw corn flour of 227.4 weight parts; The limit edged stirs; Add borax 3.1 weight parts, alum 0.1 weight part after waiting to add uncooked raw corn flour, stir 460 ± 5s, obtain main gel;
(3) the carrier glue that step (1) is made adds in stirring in the main gel that step (2) makes slowly, fully mixes control colloidal temperature; Make it remain on 56～60 ℃, measure colloidal viscosity, when viscosity reaches 22-28s; Stop to stir, make tackiness agent.
Further improve and be: the paste agent in the said step (1) is a sodium hydroxide.
Through adopting the aforementioned techniques scheme; The invention has the beneficial effects as follows: the present invention prepares earlier carrier glue (being ripe slurry) and main gel (promptly giving birth to slurry) respectively; And then, replaced original only the employing and given birth to an one-step preparation method of starching, in addition both mixing; The preparation process adopts specific churning time, shear time and temperature of reaction; The tackiness agent that makes is compared with the tackiness agent that generally uses at present, has remarkable advantages such as cohesive strength height, good penetrability, good stability, fast, the water-fast humidity resistance of rate of drying be good, can be widely used in high-grade corrugated cardboard field; Need not add baking operation and can make glue and corrugated cardboard bonding preferably, solve the problem that prying or distortion appear in position, corrugated cardboard corner.
Embodiment
Below will combine specific embodiment to specify embodiment of the present invention, how the utilisation technology means solve technical problem to the present invention whereby, and the implementation procedure of reaching technique effect can make much of and implement according to this.
Embodiments of the invention are:
Corrugated board production sticks with glue the preparation method of agent, is example with the tackiness agent for preparing 1000kg, comprises following process step:
(1) preparation of carrier glue: the clear water that in carrier tank, injects 278kg; Be heated to 29 ℃, then add the uncooked raw corn flour of 34.2kg, the limit edged stirs; Wait to add that to add mass concentration behind the uncooked raw corn flour be 33.3% sodium hydroxide 16.2kg; Then carry out shearing treatment, the shearing treatment time is 460s, obtains carrier glue;
(2) preparation of main gel: in the main body jar, inject the clear water of 441kg, be heated to 29 ℃, then add the uncooked raw corn flour of 227.4kg, the limit edged stirs, and adds borax 3.1kg, alum 0.1kg after waiting to add uncooked raw corn flour, stirs 460s, obtains main gel;
