Description
Technical field
The present invention relates to a kind of preparation method of glue used in paper-making, belong to pulp technology for making paper.
Background technology
Paper technology is one of China's four inventions, and passing east by west broadcasts, and has spread to countries in the world.Paper industry is big absolutely
Portioned product is the raw material of the branchs of industry such as printing, packaging, cultural goods, cigarette, building materials, military project.In China, paper industry
Have been developed as providing the important basic industry of raw material for national economy, the level of consumption of paper and cardboard is to weigh a state
The important symbol of family's modernization level and civilization construction.With the continuous development of China's paper industry, the consumption of sizing agent is just
Rising year by year, occupying leading position for a long time in paper industry.
Sizing agent is a kind of additive for paper making, is broadly divided into plasm-glue-blending and top sizing.Applying glue can improve paper on paper
The performances such as Zhang Kangshui, oil resistant, anti-printing-ink, while slickness, hydrophobicity, printing adaptability can be improved.Internal sizing agent is big
Cause is divided into rosin series sizing agent, synthetic sizing agent and neutral sizing agent three major types.Cypres are typically high using anionic
Molecular substance, mainly there are paraffin latex, odium stearate, polyvinyl alcohol, carboxymethyl cellulose, animal glue, casein, starch, conjunction
Resin etc..Plasm-glue-blending, which refers to, to be handled paper pulp, paper, cardboard, the chemistry for obtaining the performance of resist fluids infiltration and adding
Product.This kind of chemicals has hydrophilic radical and hydrophobic grouping, outside is orientated hydrophobic grouping in fiber surface, assigns paper
Hydrophobicity and resist fluids permeability.In addition to the paper kind such as blotting paper, filter paper, paraffin paper, cigarette paper, paper for daily use, nearly all paper
It is both needed to be glued.But current glue used in paper-making has that biocidal property is poor, and applying glue speed is slower, curing time longer problem.
The content of the invention
The technical problems to be solved by the invention：Poor for current glue used in paper-making biocidal property, applying glue speed is slower, ripe
The drawbacks of change time is longer, there is provided a kind of to add hydrochloric acid solution immersion after fresh silkworm chrysalis frying, filter residue will be filtered to obtain, through washing
Wash, dry, crushing silkworm chrysalis powder is made, using after petroleum ether degreasing silkworm chrysalis defatted seed flour, and mix and dismiss with egg white, sucrose
It is made and dismisses thing, bacillus megaterium culture is inoculated with thing to dismissing, after culture sterilizing, is stirred with polyvinyl alcohol water solution etc.
It is mixed to prepare the method for glue used in paper-making.Preparation process of the present invention is simple, and gained glue used in paper-making applying glue speed is fast, utilizes silkworm chrysalis
Defatted seed flour and egg white etc. are obtained to dismiss thing, then is cultivated by being inoculated with bacillus megaterium, improves toughness and curing speed, increases
Strong bacteriostasis property, efficiently solves that sizing agent biocidal property is poor, curing time longer problem.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
（1）Weigh 200~400g fresh silkworm chrysalis to add in iron pan, 10~15min of frying under the conditions of 300~500 DEG C, will
Silkworm chrysalis in mass ratio 1 after frying:10 add in the hydrochloric acid solution of mass fraction 3%, soak 15~25min, filtering, obtain filter residue, use
After deionized water is washed 2~4 times, it is put into baking oven, dry 20~30h at a temperature of 60~70 DEG C, crushed after being dried 15~
20min, obtain silkworm chrysalis powder；
（2）By above-mentioned silkworm chrysalis powder in mass ratio 1:10 mix with petroleum ether, using soxhlet type, in 50~60 DEG C of temperature
8~10h of lower extraction, is filtered after extraction, obtains filter residue, put it into baking oven, and 10~12h is dried at a temperature of 70~80 DEG C, is done
Crushed after dry, cross 80~100 mesh sieves, obtain silkworm chrysalis defatted seed flour；
（3）Choose 6~10 Fresh Eggs, egg white is separated to obtain after broken shell, be separately added into egg white 20~30g sucrose and
The above-mentioned silkworm chrysalis defatted seed flours of 50~70g, are stirred 5~10min, obtain mixture, by mixture egg-whisk 2000~
5~10min is dismissed under 3000r/min rotating speeds, thing must be dismissed；
（4）By inoculum concentration 5~10%, bacillus megaterium is inoculated with thing to above-mentioned dismiss, is cultivated at a temperature of 30~35 DEG C
5~7h, after culture by culture under uviol lamp 5~10min of sterilization treatment, by the culture after sterilizing in mass ratio 1:3 with
The polyvinyl alcohol water solution of mass fraction 6% mixes, and after stirring 20~30min, adds 3~5g ethylene glycol diglycidylethers, stirring
Mix 1~2h, you can obtain glue used in paper-making.
The application process of the present invention：Glue used in paper-making produced by the present invention is evenly applied on the page of shaping, control
Coated weight is 8~10g/m2, coating finished, and the page after applying glue is dried into 5~6min at 105~110 DEG C, and cure 40~
50min, you can.Glue used in paper-making applying glue speed of the present invention is fast, and the curing time is short, and antibiotic property is strong, can be effectively improved page surface
Smoothness, porosity is reduced, prevent page surface fluffing and hair loss.
Compared with other method, advantageous effects are the present invention：
（1）Preparation process of the present invention is simple, is cultivated by being inoculated with bacillus megaterium, improves sizing agent toughness and curing
Speed, strengthen its anti-microbial property；
（2）Glue used in paper-making safety and environmental protection of the present invention is pollution-free, and applying glue speed is fast, and antibiotic rate is up to more than 86.9%, during curing
Between shorten 21.2~23.6% compared with other sizing agents.
