Problems solved by technology

Due to the addition of sodium hydroxide, lignin and other colored substances will be extracted from waste paper pulp, which will increase the BOD and COD values ​​of wastewater and increase the pollution load; at the same time, heating at high pH values ​​will easily cause fiber damage, resulting in "alkaline blackening" "Phenomenon, intensity, whiteness decrease
[0004] Alkaline heating deinking requires energy consumption, large amount of waste water, complex composition and difficult to handle, low utilization rate of waste residue, and terminal treatment of waste water and waste residue increases the cost of waste paper recycling. The sustainable development of the paper industry urgently needs a low-cost Cost comprehensively utilizes the clean production technology of waste paper, which is also the purpose of the present invention

Abstract

The invention discloses a N-β-aminoethyl-γ-aminopropyl polyoxyethylene polyoxypropylene polyorganosiloxane and a preparation method thereof. The preparation method comprises the following steps: (1) mixing polyether N220 , polyether N330 and other reactions to obtain intermediate A; (2) mix octamethylcyclotetrasiloxane, N-β-aminoethyl-γ-aminopropylmethyldimethoxysilane hydrolyzate, add hydrogen Potassium oxide is reacted to obtain intermediate B; (3) Intermediate A, intermediate B, and 3-glycidyl propyl (dimethoxy) methylsilane are added in isopropanol successively, reacted for 3-15 hours, and cooled , add glacial acetic acid, adjust the pH to 6-7, and get final product. The invention has good affinity and dispersing effect on ink ions, promotes the separation of ink and fiber, prevents redeposition and contamination of ink, replaces traditional sodium silicate, and does not need heating in the process of deinking pulp at room temperature, improving pulp At the same time, the energy consumption of heating is saved, and the load and difficulty of deinking wastewater treatment are greatly reduced.

Description

Technical field[0001]The present invention relates to the field of chemical techniques, and more particularly to an N-β-aminoethyl-γ-aminopropylene polyoxyethylene polyoxypropylene polyorphoxy, and the preparation method thereof.Background technique[0002]With the enhancement of people's environmental awareness and the urination of social resources, waste paper reuse has received unprecedented attention, and various waste paper regeneration utilization technology has emerged. Among them, the use of waste paper production of high quality production paper has always been the development direction of waste paper utilization technology. During the production of high quality paper, the waste paper is necessary or sufficiently de-de-depleting treatment is a key link during the waste paper pulping process. Since various waste papers are more or less printed, especially waste newspapers, waste books, etc., are printed with ink, which is not easy to remove due to ink in the pulping process, a...
