Problems solved by technology

[0003] Based on this, various optical brighteners with negative impacts, such as VBL, UBL, VRL, RDL, etc., used in the traditional pulp and paper industry, textile industry and dyeing and finishing industry, can no longer meet the needs of market consumption. The main reasons are as follows : The fluorescent value of the product whitened by fluorescent whitening agent is too high, reaching 8.0-18.0%; the gloss and color retention are poor; it is not resistant to hard water (the whitening effect will be lost when the water hardness is greater than 300ppm) and the water quality is seriously polluted. Conducive to improving environmental quality and other defects
In addition, the fluorescent components in the fluorescent whitening agent have strong radiation and carcinogenicity to the human body and various organisms, and the radiation dose can reach 4.76×10 -3 Rad (rad), if such ingredients remain in the product, it will inevitably pose a threat to human health

Embodiment 1

[0191] The present embodiment is the main material EDTA disodium salt cross-linked 2-(4-complex fatty acid (C 12 / C 17 ) The preparation example of polyoxyethylene (6) ether sorbitol secondary ester, as shown in table 9:

[0192] Table 9 The real situation of the main material feeding formula for industrial synthesis production

[0193]

[0194] Explanation: the feeding amount in Table 9 refers to the actual feeding amount of each unit in the process of implementing the present invention. In the actual production operation process, each unit is used as a unit of measurement, and each batch of products produced can be composed of 50 to 100 units.

[0195] The operating procedures and control rules of the production process of the above-mentioned main materials are still carried out according to the method in 4; the reaction principle is also carried out according to the methods of reaction formulas (1), (2), (2a), (3) and (4). In addition, during the cross-linking reaction...

Embodiment 2

[0198] The present embodiment prepares with the EDTA disodium salt cross-linking type 2-(4-complex fatty acid (C 12 / C 17 ) Polyoxyethylene (6) ether sorbitol secondary ester is the main material, and the preparation of the optimized combination formula is carried out, as shown in Table 10 below:

[0199] Table 10 optimizes combination formula example

[0200]

[0201] The feeding procedure, operation and control rules of the above-mentioned optimized combined formula are still carried out with reference to the method described in 4. It’s just more convenient to suppress foaming and foam treatment in the process of industrial production. When the foam in the material system rises to a height of 30-50cm or is about to flow out of the container, the discharge valve at the bottom of the container can be slowly discharged to another container one by one. It is stored in a container to help reduce unnecessary waste of materials, and it is also conducive to the smooth progress ...

Abstract

The invention relates to a compound fatty acid color and brightness regulator, a preparation method and application thereof. The compound fatty acid color brightness regulator comprises a main body material, which is formed by compounding and cross-linking composite fatty acid sorbitol secondary ester, C12 saturated fatty acid polyoxyethylene (6) ether and C17 saturated fatty acid polyoxyethylene(6) ether through potassium hydroxide and EDTA disodium salt, wherein the compound fatty acid in the compound fatty acid sorbitol secondary ester is C12 saturated fatty acid and C17 saturated fatty acid. According to the invention, the compound fatty acid color brightness regulator can effectively improve the whiteness of plant fibers such as paper pulp and textile products, the added value is high, the gloss and color retention property is excellent, the color and brightness of various products treated by the regulator are pure natural artistic, and the regulator is free of fluorescence valueand radiance, environmentally friendly, sanitary, low in application cost and high in cost performance.

Description

technical field [0001] The invention relates to the technical field of organic synthesis and pulping and papermaking technology, in particular to a complex fatty acid color brightness regulator and its preparation method and application. Background technique [0002] With the rapid development of my country's modernization and the continuous improvement of people's living standards, the requirements for various finished paper (or paper products), textiles and dyeing and finishing products produced by the pulp and paper industry, textile industry and dyeing and finishing industry are getting higher and higher. At the same time, it is also required to improve the quality of environmental protection, save energy and reduce emissions, reduce environmental pollution, promote and improve the comprehensive utilization of natural resources and circular economy, thereby accelerating industrial transformation and upgrading, and promoting the sustainable and healthy development of nation...
