preparation example Construction

[0049] The second aspect of the present invention provides a method for preparing a flame-retardant waterproof and oil-repellent finishing agent, comprising the following steps:

[0050] S1: Add the dried and dehydrated acrylate into the reactor, then add the solvent, and stir until dissolved at 60-70 degrees Celsius;

[0051] S2: Add fluoroester and compound A containing ring structure to step S1, cool down to 20-35 degrees Celsius, add initiator, polyoxyethylene lauryl ether, stir for 10-30 minutes, then stop stirring, and react 1- 2 hours;

[0052] S3: washing and purifying the reactant obtained in step S2 with methanol to obtain a flame-retardant, waterproof and oil-repellent finishing agent.

[0053] The method of using the flame-retardant, waterproof and oil-repellent finishing agent in the present invention is not particularly limited, and the fabric can be finished and used according to methods well known to those skilled in the art. For example, after diluting the f...

Embodiment 1

[0058] A flame-retardant waterproof and oil-repellent finishing agent, the preparation raw materials include 60 parts of stearyl acrylate, 24 parts of hexafluoro-2-methylisopropyl acrylate, 15 parts of compound A, azobisisobutyronitrile 0.03 parts, 5 parts of polyoxyethylene lauryl ether, and 100 parts of methyl ethyl ketone.

[0059] The structural formula of the described compound A part is: CAS number 6633-79-0.

[0060] The weight ratio of the stearyl acrylate to hexafluoro-2-methylisopropyl acrylate is 2.5:1.

[0061] The weight ratio of the hexafluoro-2-methylisopropyl acrylate to the compound A is 1.6:1.

[0062] Octadecyl acrylate, CAS No.: 4813-57-4, purchased from Zhejiang Kangde New Material Co., Ltd.; Hexafluoro-2-methylisopropyl acrylate, CAS No.: 53038-41-8, purchased from Xiamen Hui Jia Biotechnology Co., Ltd.

Abstract

The invention belongs to the technical field of processing finishing agents, and particularly relates to a flame-retardant, waterproof and oil-proof finishing agent and a preparation method thereof. The invention provides the flame-retardant, waterproof and oil-proof finishing agent. The flame-retardant, waterproof and oil-proof finishing agent is prepared from the following raw materials in parts by weight of 50-80 parts of acrylate, 10-50 parts of fluoroester, 5-17 parts of a compound A containing a cyclic structure, 0.01-0.05 part of an initiator and 80-100 parts of a solvent. The flame-retardant, waterproof and oil-proof finishing agent prepared by the invention has relatively high waterproof and oil-proof effects when being used on the surface of a fabric, and has relatively high flame retardant property, and in a flame retardant property test, the flame retardant grade of the finishing agent prepared by the invention is 94-V0. Besides, the waterproof flame-retardant processing finishing agent disclosed by the invention does not adopt fluorine-containing monomers such as PFOS and PFOA and the like, meets environmental protection requirements, has small harm to human bodies, and is an ideal flame-retardant, waterproof and oil-proof finishing agent.

Description

technical field [0001] The invention belongs to the technical field of finishing agents, and more specifically relates to a flame-retardant, waterproof and oil-repellent finishing agent and a preparation method thereof. [0002] technical background [0003] With the continuous improvement of living standards, people have begun to pay great attention to the quality of various daily necessities. For example, all kinds of common textile products have begun to pay attention to their functionality and safety in addition to their beauty and practicality. Such as curtains, baby products that are common at home, or seat fabrics and interior fabrics used in various public transportation vehicles, hospitals, offices and other public places, people also pay attention to their aesthetics and practicality. Began to pay attention to its waterproof / fouling-proof and flame-retardant functions. In addition to being easy to take care of, it can also reduce damage at critical moments and prote...
