Embodiment 1

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

[0042] (1) Preparation of phosphoric acid ester:

[0043] Take 34g (0.28mol) of pentaerythritol in how many grams of POCl 3 Stir in a three-necked flask, heat to 75°C, react for 24h, cool and filter, wash with dichloromethane, dry to constant weight and recrystallize with glacial acetic acid, add 200ml of deionized water into a three-necked flask, and react with 100°C 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 of B, C, D and a three-neck flask, add 16.8g of concentrated sulfuric acid and 5.11g of DCC / DIC as a catalyst, heat up to 70-200°C, react for 3-10 hours, cool, filter and dry to obtain solid E.

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

[0047] The p...

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 preparation method of 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 also increasing. Because harmful bacteria are widely distributed in nature, and there are various types and large numbers, they seriously threaten human health. Diseases caused by bacterial transmission and infection have become a major social problem and have attracted widespread attention. Therefore, research on disinfectants is particularly important. Guanidine disinfectant is a type of disinfectant and antibacterial agent that has been widely used in recent years. It is easy to use and has a wide antibacterial spectrum, low toxicity, and no irritation. , It can also be used for the disinfection of fi...
