Embodiment 1

[0041] A method for preparing a flame-retardant and antibacterial composite modifier used in the fiber field. The specific steps are:

[0042] (1) Preparation of phosphate ester:

[0043] How many grams of POCl are there in 34g (0.28mol) of pentaerythritol 3 In a three-necked flask, heated to 75℃, reacted for 24h, cooled and filtered, washed with dichloromethane, dried to constant weight and recrystallized with glacial acetic acid, then added to a three-necked bottle of deionized water 200ml, and reacted at 100℃ 2h, filtered and dried to obtain solid B0.28mol (50.4g).

[0044] (2) Preparation of flame-retardant and antibacterial composite materials:

[0045] Take 0.28mol B, C, D and three-necked flask, add 16.8g concentrated sulfuric acid, 5.11g DCC / DIC as catalyst, heat up to 70~200℃, react for 3~10h, cool, filter and dry to obtain solid E.

[0046] The composite material obtained by the present invention has the following characteristics:

[0047] The prepared composite material has f...

Abstract

The invention relates to a flame retardant anti-bacterial composite modifier used in the fiber field and a preparation method thereof. The active components of the flame retardant anti-bacterial modifier are alkyl phosphate and alkyl guanidine; and the preparation method of the flame retardant anti-bacterial composite modifier comprises the following steps of: (1) preparing alkyl tetrol phosphoric acid ester; and (2) taking alkyl tetrol phosphate ester B, alkyl guanidine C and p-benzoic acid alkyl nitrile D which have the equal amount of substance, adding concentrated sulfuric acid and dicyclohexylcarbodiimide / N, N'-diisopropyl carbodiimide (DCC / DIC) as catalysts, wherein the mass ratio of the concentrated sulfuric acid to the alkyl tetrol phosphate ester B is 1:2-4, the mass ratio of DCC / DIC to the alkyl guanidine C is 1:2-5, rising the temperature to 70 to 200 DEG C, after reacting for 3-10h, cooling, filtering and drying to obtain the solid composite modifier E. The flame retardant anti-bacterial composite modifier has the advantages of having the flame retardant anti-bacterial performance, good thermal stability, being capable of meeting the high temperature processing requirement and being not easy to degrade; and products machined and prepared by using the composite modifier are not easy to oxidize and change color; and the flame retardant anti-bacterial composite modifier is widely applied.

Description

【Technical Field】 [0001] The invention relates to the technical field of functional materials, in particular to a method for preparing a flame-retardant and antibacterial composite modifier used in the fiber field. 【Background technique】 [0002] With the rapid development of industry and the improvement of people's living standards, especially the awareness of health is constantly increasing. Because harmful bacteria are widely distributed in nature, and there are many kinds and large numbers, they seriously threaten human health. Diseases caused by infections transmitted by bacteria have constituted a major social problem and aroused widespread concern. Therefore, the research on disinfectants is particularly important. Guanidine disinfectant is a kind of disinfectant and antibacterial agent that has been used more in recent years. It is convenient to use and has a wide range of applications due to its wide antibacterial spectrum, low toxicity and no irritation. In addition t...
