Problems solved by technology

The focus of this technical solution lies in the improvement of the structure of the daily chemical cream bottle, but no specific formula is provided for the specific material, only the raw material is given, but for the material, the difference in the formula of the raw material will bring more problems to the final product. large difference, and for this scheme, it only gives the possibility of a degradable material, for the antibacterial performance, those skilled in the art really cannot predict
[0006] It can be seen from this that in the prior art, research on degradable daily chemical bottles has been gradually started, but how to improve the quality of degradable daily chemical bottles, especially the quality of appearance, material, and optics, is currently rare. technology disclosure

Embodiment 1

[0078] A degradable daily chemical bottle and a preparation method thereof, comprising the following steps:

[0079] Step 1) preparation of plasticized starch

[0080] 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 modified starch.

[0081] Step 2) Glycerol plasticized starch is blended with polybutylene succinate to obtain a modified starch / PBS material.

[0082] 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 were stirred at 140° C. for 35 minutes to o...

Embodiment 2

[0089] Preparation of polyurethane paint

[0090] Wherein, the matting polyurethane paint comprises 50 parts of polyether polyol, 20 parts of isocyanate, 2 parts of catalyst, and 20 parts of solvent;

[0091] Described polyether polyol is polyoxypropylene glycol;

[0092] Described isocyanate is toluene diisocyanate;

[0093] Described solvent is ethyl acetate;

[0094] Described catalyst is stannous octoate.

Embodiment 3

[0096] Another kind of matting polyurethane paint provided by the invention;

[0097] In some embodiments, the matting polyurethane paint includes 60 parts of polyether polyol, 20 parts of isocyanate, 3 parts of catalyst, 20 parts of solvent, and 10 parts of alcohol containing benzene ring;

[0098] Described polyether polyol is polyoxypropylene glycol;

[0099] Described isocyanate is toluene diisocyanate;

[0100] Described solvent is ethyl acetate.

[0101] Described catalyst is stannous octoate.

Abstract

The invention relates to a preparation method of a degradable matting daily chemical bottle, which is characterized in that a matting polyurethane paint coating is used to carry out matting treatment on the daily chemical bottle, and the matting polyurethane paint coating comprises 50-60 parts of polyether polyol, 20-30 parts of isocyanate, 1-5 parts of a catalyst, 20-30 parts of a solvent, and 10-20 parts of benzene ring-containing alcohol. The matting polyurethane paint coating contains benzene ring-containing alcohol, and the polyurethane paint coating has certain matting performance due to the addition of the alcohol; in addition, microwaves with multiple frequency bands are used for removal in the polyurethane paint curing process, the extinction effect is further improved, and the daily chemical bottle prepared through the method is high in visual sense.

Description

technical field [0001] The invention belongs to the field of biocomposite degradable materials, in particular to a matting degradable daily chemical 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. Traditional daily chemical bottles mostly use non-degradable glass, non-degradable polymer polyester, etc. Since the daily chemical bottles are disposable, there is a huge waste of resources and environmental pollution problems, and, because the daily chemical bottles are filled with chemicals, such items are difficult to clean up, which also makes the use of such daily chemical bottles The difficulty and cost of recycling have increased. In summary, the impact of daily chemical bottles on the environment and resources has attracted widespread attention. [0003] In addition, for daily che...
