Description
Technical field
The present invention relates to pulp technology for making paper, and in particular to a kind of inorfil reinforcing agent.
Background technology
With the continuous development of modern humans' civilization, paper has been increasingly becoming the fields such as industry, agricultural, business, construction industry
Indispensable material, and it is not exclusively limited only to the use of the culture fields such as writing, paper requirements amount is also rising year by year.It is many
It is well known, paper, cardboard raw material be mainly plant fiber, and just contain a large amount of plant fiber in trees, therefore to trees
It is a large amount of felling so that China forest cover face is fallen sharply so that animal lose habitat, soil sandification, weather be deteriorated, serious shadow
Demand degree of the ecological balance in the China Xiang Liao due to different field to paper various aspects of performance is different, merely with plant fiber
Copy paper cannot be satisfied specific demand of the people to paper performance.Therefore, it is obtained in recent years using inorfil paper technology
Faster development.
The country has relevant report reflection flyash/bastard coal mineral wool to have similarity in shape with plant fiber at present,
Treated flyash/gangue fibre whiteness can reach 76 DEG C,（It is 54 that national standard, which limits electro-photographic paper highest whiteness,
DEG C, it is 94 DEG C that national standard, which limits uncoated Cultural Paper highest whiteness,）, therefore, flyash/bastard coal mineral wool can be used as one kind
Very friendly fiber carries out mixing papermaking with plant fiber.But since flyash/bastard coal mineral wool belongs to inorfil, have
The disadvantage that brittleness is big, intensity is low, directly in application, can be only applied to the paper pulp filler material of papermaking or answered instead of Activities of Some Plants fiber
For cardboard, low-grade wrapping paper.If flyash/bastard coal mineral wool is modified processing, it will greatly improve it in papermaking
The application range and range of aspect.The present invention is with starch, and styrene, butyl acrylate is raw material, by emulsion polymerisation process system
For a kind of novel inorganic fiber reinforcing agent is gone out, reinforcing agent is used for flyash/gangue fiber surface, reaches the increasing to fiber
Pretend use, can so that flyash/bastard coal mineral wool in paper-making industry, plant fiber can be saved, additionally it is possible to reduce slurrying
The journey produced pollution reduces papermaking cost.
Invention content
The purpose of the present invention is to provide a kind of preparation method of pulping and paper-making inorfil reinforcing agent, the reinforcing agents
Flyash/gangue fiber surface can be modified, change the shortcomings that its rigidity is strong, brittleness is big, easy fracture.
A kind of preparation method of pulping and paper-making inorfil reinforcing agent, it is characterised in that this method includes following step
Suddenly:
10 weight starch, 0.5 parts by weight sodium hydrogensulfite, 0.02 parts by weight of ferrous sulfate are taken to be added to reaction kettle at room temperature
In, 70 parts by weight of deionized water are added, solution is to slowly warm up to 90 DEG C ~ 95 DEG C, continues constant temperature magnetic force by magnetic agitation 30min
50min is stirred, starch is made fully to be gelatinized.The starch of above-mentioned gelatinization is cooled to 80 DEG C or so, be added 20 parts by weight of styrene and
2.5 parts by weight hydrogen peroxide are slowly added dropwise in Butyl Acrylate Monomer after stirring evenly, 1.5 ~ 2 h are added dropwise, and add 8 weight
Part functionalization MOF-SO3@KIT-6 nanometer bodies, constant temperature is stirred to react 90 min at 80 DEG C, discharges to get novel inorganic fiber
With reinforcing agent reinforcing agent.
Advantageous effect：The present invention provides a kind of preparation method of pulping and paper-making inorfil reinforcing agent, passes through starch
Reinforcing agent is adsorbed in fiber surface, forms one layer of adsorbed film by the suction-operated to flyash/bastard coal mineral wool, to reach fine
The humidification of dimension.In addition functionalization MOF-SO3 KIT-6 Nanostructured bulks are added in preparation process, are added lower
Polymer physics, chemistry and mechanical property are just remarkably improved under amount, the two synergistic effect can increase substantially flyash/bastard coal
The enhancing of mineral wool is modified.

The inorfil prepared as follows to the embodiment of the present invention 1 ~ 9 and comparative example 1 ~ 9 carries out performance with reinforcing agent
Test：1, the enhancing of flyash/bastard coal mineral wool is modified
It weighs 99 g water to be placed in beaker, the enhancing agent emulsion of 1 g is added thereto, fully shakes up, adds the fine coal of 2 g
Ash/bastard coal mineral wool, the stir speed (S.S.) using 50 r/min make it be uniformly dispersed, and after standing 1 h, suction filtration obtains enhancing modified
Flyash/bastard coal mineral wool, then will enhancing flyash/bastard coal mineral wool be put into baking oven and be dried for standby.
2, fiber-reinforced modified effect assessment
By reinforcing fiber, drying to constant weight, weighs the reinforcing fiber of 50g in mortar, grinds 80 times, and 120 mesh are sieved 60 times, claims
The quality of remaining reinforcing fiber, calculates its sieving rate after amount sieving.
Sieving rate %=（M0-M）/M0×100%
In formula：M0The dry weight of fiber before-sieving（g）；The dry weight of residual fiber after M-sieving（g）.
Inorfil reinforcing agent Evaluation results
As seen from the above table, using the inorfil prepared under the conditions of embodiment 1 flyash/bastard coal mineral wool is acted on reinforcing agent
When its sieving rate it is minimum, remaining embodiment effect unobvious illustrates that the reinforcing agent enhancing effect prepared under the conditions of embodiment 1 exceeds
That expects is good, when styrene and constant Butyl Acrylate Monomer total amount, with the change of monomer ratio dosage, flyash/coal
The sieving of spoil fiber takes the lead in increasing after reducing, the possible reason is as monomer weight ratio is higher, flyash/bastard coal mineral wool table
The film toughness that bread covers increases, but when mass ratio is excessively high, and excessive styrene is unfavorable for enhancing agent emulsion on fiber
Good filming, therefore sieving rate is on a declining curve.In addition the addition of 1 ~ 5 functions MOF-SO3@KIT-6 nanometer bodies of comparative example
And its parts by weight are affected to the enhancing performance of reinforcing agent, comparative example 5 ~ 9 illustrates to prepare former when inorfil reinforcing agent
The selection of material and the selection of condition have prominent influence to reinforcing agent performance.
