Abstract
The invention discloses a novel deodorant for papermaking and a preparation method thereof, which are applied to the field of papermaking and solve the technical problem that the existing papermaking product has peculiar smell, and the technical scheme is characterized by comprising the following components in parts by weight: 15-25 parts of isoquinazolinone, 5-8 parts of an oxidation mixture, 12-18 parts of a flocculation mixture, 5-8 parts of disodium ethylenediamine tetraacetic acid, 3-7 parts of edible essence and 44-60 parts of distilled water, and has the technical effects of realizing the deodorization effect of paper products and improving the quality.
Description
Technical Field
The invention relates to the field of papermaking, and particularly relates to a novel papermaking deodorant and a preparation method thereof.
Background
In the production process of bobbin paper, the main raw materials are recycled waste materials from recycled yellow paper boards, industrial pipes and the like, the production raw materials can generate a large amount of impurity mixed liquid in the processes of smashing, mixing and cooking, and the substances often generate great peculiar smell, so that a large amount of chemical substances can be doped into paper pulp by a plurality of paper making enterprises, and the chemical substances are utilized for deodorization, but the chemical substances can generate a large amount of environmental pollution when being mixed into liquid, and the stable and reliable deodorization effect cannot be guaranteed.
Disclosure of Invention
The invention aims to provide a novel deodorant for papermaking and a preparation method thereof.
The technical purpose of the invention is realized by the following technical scheme: a novel deodorant for papermaking is characterized in that: comprises the following components in parts by weight: 15-25 parts of isoquinazolinone, 5-8 parts of an oxidation mixture, 12-18 parts of a flocculation mixture, 5-8 parts of disodium ethylenediamine tetraacetic acid, 3-7 parts of edible essence and 44-60 parts of distilled water.
Preferably, the composition comprises the following components in parts by weight: 20 parts of isoquinazolinone, 7 parts of an oxidation mixture, 15 parts of a flocculation mixture, 6 parts of ethylene diamine tetraacetic acid, 5 parts of edible essence and 47 parts of distilled water.
Preferably, the oxidizing mixture comprises hydrogen peroxide and potassium permanganate.
Preferably, the ratio of the hydrogen peroxide to the potassium permanganate is 1: 1.5-1: 3.
Preferably, the flocculating mixture comprises ferrous sulphate and sodium bicarbonate.
Preferably, the ratio of the ferrous sulfate to the sodium bicarbonate is 2: 1-2.5: 1.
Preferably, the method comprises the following steps:
s1: mixing the isoquinazolinone, the oxidation mixture, the flocculation mixture, the ethylene diamine tetraacetic acid disodium, the edible essence and the distilled water according to a certain proportion in a reaction kettle for mixing for 2 hours;
s2: performing low-temperature cooling, and keeping the temperature at 10-15 ℃;
s3: exhausting;
s4: and (4) feeding, namely directly taking out the reagent from the reaction kettle and feeding the reagent into the paper pulp for mixing.
In conclusion, the invention has the following beneficial effects:
1. the chemical components of isothiazolinone are utilized, the effects of sterilizing and removing peculiar smell in the mixed slurry can be stably realized, the requirements on working environment are low, the requirements on different component environments can be met, and effective time limit is guaranteed;
2. the addition of the flocculation mixture can accumulate and sink part of foreign matters mixed in the paper pulp, and reduce the peculiar smell possibly generated in the reaction processes of long-time fermentation and the like of the foreign matters;
3. the addition of the oxidizing mixture utilizes the stable chemical oxidizing property of the oxidizing mixture to perform the functions of sterilization, bleaching and the like, thereby further reducing the peculiar smell in the paper pulp.
Detailed Description
The present invention will be described in further detail below.
The first embodiment is as follows:
s1: mixing 15 parts of isoquinazolinone, 2 parts of hydrogen peroxide, 3 parts of potassium permanganate, 8 parts of ferrous sulfate, 4 parts of sodium bicarbonate, 5 parts of disodium ethylene diamine tetraacetate, 3 parts of edible essence and 60 parts of distilled water in a reaction kettle in proportion for 2 hours;
s2: performing low-temperature cooling, and keeping the temperature at 10 ℃;
s3: exhausting;
s4: and (4) feeding, namely directly taking out the reagent from the reaction kettle and feeding the reagent into the paper pulp for mixing.
Example two: s1: mixing 20 parts of isoquinazolinone, 2 parts of hydrogen peroxide, 5 parts of potassium permanganate, 10 parts of ferrous sulfate, 5 parts of sodium bicarbonate, 6 parts of disodium ethylene diamine tetraacetate, 5 parts of edible essence and 47 parts of distilled water in a reaction kettle in proportion for 2 hours;
s2: performing low-temperature cooling, and keeping the temperature at 12 ℃;
s3: exhausting;
s4: and (4) feeding, namely directly taking out the reagent from the reaction kettle and feeding the reagent into the paper pulp for mixing.
Example three: s1: mixing 25 parts of isoquinazolinone, 2 parts of hydrogen peroxide, 6 parts of potassium permanganate, 12 parts of ferrous sulfate, 6 parts of sodium bicarbonate, 8 parts of disodium ethylene diamine tetraacetate, 7 parts of edible essence and 44 parts of distilled water in a reaction kettle according to a certain proportion, and mixing for 2 hours;
