Embodiment 1

[0056] A degradable daily chemical bottle and a preparation method thereof, comprising the following steps:

[0057] Step 1) preparation of plasticized starch

[0058] Glycerin and acetylated distarch phosphate are heated and plasticized to obtain glycerin plasticized starch. The plasticizing condition is that the dosage ratio of glycerol and starch is 3:10. Firstly, the starch and glycerin are blended, vacuum treated at 80°C for 70h, and then plasticized at 140°C, plasticized and stirred for 20min at a stirring speed of 50rpm , to obtain plasticized starch.

[0059] Step 2) Glycerol plasticized starch is blended with polybutylene succinate to obtain a modified starch / PBS material.

[0060] The plasticized starch obtained by step 1) is blended with polybutylene succinate, wherein the ratio of plasticized starch to polybutylene succinate is 3:10, wherein the plasticized starch is 3 parts, 10 parts of polybutylene succinate, and 1 part of calcium chloride as an auxiliary plas...

Embodiment 2

[0067] A self-cleaning, antibacterial and degradable daily chemical bottle preparation, comprising:

[0068] Preparation of silver series antibacterial agent:

[0069] Step 1), prepare high fluidity hydrogel silver-loaded antibacterial agent

[0070] Using N-isopropylacrylamide as raw material, dextran as cross-linking agent, ammonium persulfate as initiator and tetramethylethylenediamine as catalyst, the hydrogel was prepared.

[0071] In parts by mass, take 10 parts of N-isopropylacrylamide and add it to 1000 parts of water, dissolve and mix evenly, then add 0.05 part of dextran, stir, add 0.1 part of tetramethylethylenediamine, and 0.1 part silver nitrate solution and 0.04 part NaBH 4 , heating up to obtain a hydrogel containing nano-silver particles.

[0072] Step 2) Load the high fluidity hydrogel silver-loaded antibacterial agent prepared in step 1 on the surface of the daily chemical bottle.

[0073] Get the daily chemical bottle prepared in Example 1, inject the an...

Embodiment 3

[0075] A self-cleaning, antibacterial and degradable daily chemical bottle preparation, comprising:

[0076] The preparation method of silver series antibacterial agent comprises the steps:

[0077] Step 1), prepare high fluidity hydrogel silver-loaded antibacterial agent

[0078] Using N-isopropylacrylamide as raw material, dextran as cross-linking agent, ammonium persulfate as initiator and tetramethylethylenediamine as catalyst, the hydrogel was prepared.

[0079] In parts by mass, take 10 parts of N-isopropylacrylamide and add it to 1000 parts of water, dissolve and mix evenly, then add 0.05 part of dextran, stir and dissolve, add 0.1 part of tetramethylethylenediamine, and 0.2 parts of silver nitrate solution and 0.06 parts of NaBH 4 , heating up to obtain a hydrogel containing nano-silver particles.

[0080] Step 2) Load the high fluidity hydrogel silver-loaded antibacterial agent prepared in step 1 on the surface of the daily chemical bottle.

[0081] Get the daily ...

Abstract

The invention discloses a self-cleaning antibacterial degradable daily chemical bottle and a preparation method thereof. The daily chemical bottle contains a silver antibacterial agent, the silver antibacterial agent has a film-forming property, and the preparation method of the silver antibacterial agent comprises the following steps: taking 5-10 parts by mass of N-isopropylacrylamide and addinginto 1000 parts by mass of water, dissolving and uniformly mixing, adding 0.01-0.2 part of a cross-linking agent, stirring, adding 0.01-0.05 part of an initiator, 0.1 part of a catalyst, 0.1 part of asilver nitrate solution and 0.01-0.8 part of a reducing agent, and heating to obtain hydrogel containing nano-silver particles, namely the silver-based antibacterial agent. The obtained self-cleaningantibacterial degradable daily chemical bottle has beneficial mechanical properties and heat resistance, and also has long-lasting antibacterial property and self-cleaning property.

Description

technical field [0001] The invention belongs to the field of biocomposite degradable materials, in particular to a self-cleaning degradable plastic bottle and a preparation method thereof. Background technique [0002] The current demand for daily chemical products continues to increase, and the market for daily chemical bottles used to hold these daily chemical products is also growing. However, the traditional daily chemical bottles have relatively high requirements and are only used for the most basic packaging functions. , but because the price and cost of daily chemical products are getting higher and higher, and at the same time, due to the scope of use of daily chemical products, less antibacterial materials are added or the antibacterial performance is limited. Therefore, their antibacterial performance is not strong, so cosmetics also exist The possibility of contamination, based on the above reasons, consumers expect to be able to use up all the daily chemical prod...
