Problems solved by technology

Natural antibacterial agents are restricted by raw materials and processing conditions, and it is not yet possible to achieve large-scale marketization
Organic antibacterial agents have the advantages of fast sterilization speed and wide antibacterial range, but there are also problems such as poor heat resistance, easy oozing, toxicity of leachate, and short service life of washing resistance, so their use has great limitations.
Inorganic antibacterial agents are mainly silver antibacterial agents, which are characterized by safety, heat resistance, and durability. They are currently widely used in fibers, plastics, and building materials. The disadvantage is that they are relatively expensive. And antibacterial slow effect, can not kill bacteria quickly like organic antibacterial agents; at the same time, due to the active chemical properties of silver, it is easy to oxidize and become brown silver oxide, thereby reducing the antibacterial effect and affecting the appearance of products; In addition, inorganic Antibacterial powder has poor compatibility with polymer materials, and is easy to agglomerate in the matrix resin, which will bring great difficulties to the processing of materials such as spinning and film drawing

Embodiment 1

[0085] The preparation method of the maleate of polydecanediamine biguanide carbonate, the method may further comprise the steps:

[0086] Take 172g of 1,10-decanediamine, make it into a 40%wt aqueous solution, put it into a 1000ml three-necked bottle, pass in carbon dioxide until the pH value reaches 3, and then distill under reduced pressure to remove water. Under nitrogen protection, add 84g dicyandiamide, stir and heat up to 110°C, react for 1 hour, then heat up to 185°C for 8 hours, stop heating; after cooling, add water to dissolve the product, then add 35g maleic anhydride, The reaction was carried out at room temperature for 40 minutes, and finally the water was distilled off under reduced pressure, and dried for use.

[0087] The test results show that its number-average molecular weight is 3,800, its thermal decomposition temperature is 370°C, and there are characteristic absorption peaks of guanidinium, amine, amide, double bond and other groups in its infrared spec...

Embodiment 2

[0089] The preparation method of the acrylate of polydiethylene triamine phosphate biguanide salt, the method comprises the following steps:

[0090] Take 103g of diethylenetriamine, add it to a 250ml three-necked flask, add 20% phosphoric acid dropwise to pH = 2, then distill off water under reduced pressure; add 85g of dicyandiamide to the system, stir and raise the temperature under nitrogen protection Temperature was raised to 150°C for 5 hours, then the temperature was raised to 210°C for 8 hours, and 20 g of butyl acrylate was added, and the reaction was terminated after 100 minutes.

[0091] The test results show that its number average molecular weight is 18,000, its thermal decomposition temperature is 366°C, and there are characteristic absorption peaks of guanidinium, amine, amide, double bond and other groups in its infrared spectrum.

Embodiment 3

[0093] The preparation method of the methacrylate of polyhexamethylenediamine hydrochloride biguanide, the method comprises the following steps:

[0094] Take 116g of hexamethylenediamine, add it to a 500ml three-necked bottle, add 20% hydrochloric acid dropwise to pH=3, then distill it under reduced pressure to remove water; add 85g of dicyandiamide to the system, stir and heat up to React at 100°C for 2 hours, then raise the temperature to 160°C and react for 1 hour, then add 10g of glycidyl methacrylate, and finish the reaction after 20 minutes.

[0095] The test results show that its number-average molecular weight is 900, its thermal decomposition temperature is 365°C, and there are characteristic absorption peaks of guanidinium, amine, double bond and other groups in its infrared spectrum.

[0096] The following are the preparation examples of polyolefin functional masterbatch:

Abstract

The invention relates to a polyolefin functional master batch, a preparation method thereof and use thereof. The functional master batch is prepared by blending a polyolefine resin, a guazatine oligomer, an olefin monomer, an initiator and the like and by a method of solvent graft, solid phase graft or melt graft and has a structural formula below, wherein in the formula, R represents the guazatine oligomer grafted to molecular chains of the polyolefin, and T may be hydrogen, chlorine, methyl, or phenyl. Compared with the prior art, by blending the functional master batch prepared by the invention with the corresponding polyolefin, various products, including fibers, thin films, water pipes and other plastic products, which have high antimicrobial performance and long-lasting effect and is safe and nontoxic to human bodies can be manufactured; and meanwhile, the acidic dye and disperse dye uptake of polyolefin fibers can be improved greatly, and the surface polarity, antistatic performance and paint film adhesion of polyolefin materials can be improved.

Description

technical field [0001] The invention relates to the technical field of high molecular polymer polymerization and processing, in particular to a polyolefin functionalized masterbatch and its preparation method and application. Background technique [0002] Guanidine-based polymers (including monoguanide and biguanide salts) are one of the bioactive polymers. Guanidine-based derivatives are widely used as environmental fungicides in food factories, pharmaceutical factories, hospitals, etc., and are also used in cosmetics and textiles. , which has high-efficiency and broad-spectrum antibacterial properties, can inhibit and kill microorganisms including bacteria, molds, viruses, etc., and is safe and non-toxic to the human body. [0003] For example, British Patent GB 2182245 discloses a polyhexamethylene bisguanidine hydrochloride as an antibacterial agent; Japanese patents JP 05209195, JP 05209197, and JP 05209196 use polyhexamethylene bisguanidine hydrochloride as water treat...
