Embodiment 1

[0034]Get 100 grams of ethylene-vinyl acetate (EVA) resins, 15 grams of methacryloyl polyhexamethylenediamine guanidine nitrate, molecular weight 1000, styrene 4 grams, 1010 antioxidant 0.1 grams, join in the flask of 2000ml, then Add 1300 g of xylene, and gradually raise the temperature to 100°C. After all the solids were dissolved and nitrogen was blown to exclude oxygen, 1.3 grams of benzoyl peroxide was taken and added to the flask in 5 times within 4 hours, and the reaction was maintained at 100°C. After the reaction, the flask was cooled to room temperature, 100 g of acetone was added, and after stirring, the solid was completely precipitated, and then dried to obtain functionalized EVA. (No.: 1#)

[0035] The bonding efficiency measured by infrared spectroscopy was 75.3%.

Embodiment 2

[0037] Get 10 kilograms of ethylene-octene copolymer resin (POE), 3 kilograms of acryloyl of polyethylenediamine guanidine hydrochloride, molecular weight is 3000, 200 grams of styrene, 1.5 grams of 1010 antioxidants, 3 grams of benzoyl peroxide, 16 grams of lauryl peroxide were all put into a high-speed mixer and mixed for 2 minutes before discharging. The compound was put into a single-screw extruder, and was extruded at a speed of 60 rpm. The extruded product was collected to obtain the functionalized POE. (No.: 2#)

[0038] The bonding efficiency measured by infrared spectroscopy was 85%.

Embodiment 3

[0040] Get 5 kilograms of ethylene-propylene rubber (EPR), 100 grams of maleyl of polyethylenediamine carbonate guanidine carbonate, molecular weight is 5000, 10 grams of α-methylstyrene, 2 grams of dicumyl peroxide, all put into high-speed mixing Mix in the machine for 2 minutes and discharge. The compound was added into a twin-screw extruder, and was extruded at a speed of 50 rpm. The extruded product was collected to obtain the functionalized EPR.

[0041] The bonding efficiency measured by infrared spectroscopy was 90%. The functionalized EPR was molded to obtain a test sample, numbered as: A.

Abstract

The invention relates to a functionalized olefin copolymer, a preparation method and application thereof. The structural formula of the functionalized olefin copolymer is that: X is chlorine, methyl, ethenyl or hexyl; Y is alkane group such as methyl, ethenyl, propyl, butyl, etc.; R is polyamine and guanidinium oligomer; m, n and p are integers that are more than or equal to zero; q is integer that is more than zero; the functionalized olefin copolymer is obtained from olefin copolymer resin, polyamine, guanidinium oligomer, olefin monomer, evocating agent and antioxidant through solution reaction, frit reaction and solid phase reaction; the functionalized olefin copolymer can be used singly for preparing olefin copolymer products with antibiosis function and also can be mixed with resin together for preparing products with antibiosis function. Compared with the prior art, the invention has the advantages of safety, good antibiosis effect and long residual action, etc.

Description

technical field [0001] The invention relates to the technical field of polymer reaction and processing, in particular to a functionalized olefin copolymer obtained by reacting an oligomer containing active double bonds, amine groups and guanidine groups with an olefin copolymer. Background technique [0002] Antibacterial materials are a class of materials with antibacterial or bactericidal functions, which are made by adding one or several specific antibacterial agents. The development and application of antibacterial materials can set up a safety barrier for human health, and it has developed rapidly in recent years. Antibacterial products have huge market demand and bright development prospects. [0003] Due to the wide application of polymer materials in daily life, the requirement of their antibacterial properties is an important aspect in the field of materials. Polymer antibacterial materials can generally be obtained by the following two methods: [0004] (1) Add ...
