Description
Technical field
The present invention relates to paper making additive technical field, particularly relate to a kind of waste paper deinking agent.
Background technology
Owing to the eighties resource in last century constantly reduces, environment constantly deteriorates, and sight is turned to useless by people
Paper, if it is possible to utilize regenerated papermaking, will save substantial amounts of timber, water, electricity equal energy source, greatly reduce
Sewage discharge, reduces environmental.Develop through decades, utilize regenerated papermaking to have become as huge
Big industry.Waste paper deinking agent is a kind of to have making of the multiple effects such as infiltration, washing, emulsifying, dispersion
Paper specialty chemicals, are mainly used in the enterprise utilizing waste paper to produce paper pulp or papermaking.China is a money
The country that source is the poorest, therefore country actively promotes regenerated papermaking technology, but due to shortage property
Can excellent papermaking specialty chemicals, many imported units can not give play to due effect, and this becomes system
The about bottleneck problem of regenerated papermaking.
Along with increasing rapidly of waste paper recycling amount, deinking technology faces following problem: due to current print

Oxygen ethylene-polyoxypropylene atactic polyether 1～20 parts, sodium silicate 0～5 parts, sodium hydroxide 0～5 parts, peroxide
Change hydrogen 0～5 parts, chelating agen 0～5 parts and water 1～20 parts.
Fatty alcohol-polyoxyethylene ether, polyoxyethylenated alcohol sodium sulfate, fatty alcohol polyoxy second in the present invention
Alkene-polyethenoxy ether, PULLRONIC F68 atactic polyether can resin in emulsified ink, chemicals
And dispersion pigment；High fatty alcohol, higher fatty acids play the effect improving deinking efficiency further, make
Resin, chemicals and pigment in ink remove further；Hydrogen peroxide is for bleached fiber and toning,
And the resin in oxidation, destruction ink, promote ink to dissociate, surfactant can be improved further
Performance, preferably separates ink；Sodium silicate can suppress the too quick decomposition of hydrogen peroxide, with heavy metal from
Son forms colloform texture, helps when deinking ink to carry out peptizaiton, stops the suction again of ink particle
Attached, discoloration can be played simultaneously, prevent paper pulp yellowing；The effect of sodium hydroxide is regulation slurry
PH value be alkalescence, saponification and/or hydrolysis ink resin, make fibre swelling, fibrous absorbent and become more
Softness, so that ink particle is attached to the weakened of fiber surface, it helps loosens coating and divides
Split ink, make ink particle become less by mechanism, but will become for the waste paper containing groundwood pulp
Yellow hair is black, so the amount of the sodium hydroxide added is properly better, excess can cause paper pulp to turn yellow or blackening；
The effect of chelating agen is and the complex of heavy metal ion formation solubility, thus stops heavy metal ion to be divided
Xie Bingke prevents adsorbing again of ink particle.The present invention has synergism between each component, accurately controls
The consumption making each component has reached the effect that under low temperature, deinking deinking efficiency is good, reduces pulping temperature
