Degradable non-toxic sucker material with cold and hot application

Abstract

The invention discloses a degradable non-toxic sucker material with cold and hot application, and belongs to the technical field of high polymer materials. The degradable non-toxic sucker material with the cold and hot application is mainly prepared from the following raw materials: hydroxyapatite powder, calcium phosphate, polylactic acid, polycyclohexyl carbonate, polyhydroxyalkanoate, bagasse fibers, glycerin, mung bean starch, polyethylene glycol, polyvinylpyrrolidone, xanthan gum, konjac glucomannan, a stabilizer, a modifier, sodium alginate and POE. According to the degradable non-toxicsucker material with the cold and hot application, through blending modification and surface treatment, the sucker material has the characteristics of thermal resistance and ageing resistance. The degradable non-toxic sucker material with the cold and hot application can be used for drinking cold beverages and hot beverages, the surface is bright and clean, liquid can be easily sucked, and the degradable non-toxic sucker material with the cold and hot application is degradable, environmentally friendly, harmless, and good in thermal resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a degradable and non-toxic cold and hot straw material. Background technique [0002] In the 19th century, Americans liked to drink ice-cold light wine. In order to avoid the heat in the mouth and reduce the freezing strength of the wine, they did not drink directly with their mouths, but used hollow natural straws to drink. [0003] In 1888, American cigarette manufacturer Marvin Stone got inspiration from cigarettes and invented paper straws, but its durability has been criticized by people. Later, due to its cheapness and durability, plastic began to become the preferred material for the manufacture of disposable products, so plastics were also used in the production of straws. Plastic straws with strong flexibility and beautiful appearance completely replaced almost all of the straw materials. application space. [0004] Plastic straws are relatively inconspicuous...

Problems solved by technology

[0006] At present, the alternatives to plastic straws on the market are paper straws and metal straws. However, compared with plastic straws and other recyclables, the cost is lower, and it saves oil and fresh water resources. Paper straws are not water-resistant, and metal straws are heat-conducting and easy to scratch. Burns, the two do not have a cost advantage, at the same time they consume a lot of wood and metal resources, and the post-processing stage will consume more environmental resources

[0007] The polylactic acid degradable straw is made of a new type of bio-based and renewable biodegradable material, which has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, eventually producing carbon dioxide And water, does not pollute the environment, which is very beneficial to the protection of the environment, is recognized as an environmentally friendly material is very stable, but its thermal stability is not good, and the degradable straw products including polylactic acid on the market are not heat-resistant Poor performance, can only be used as a straw for cold drinks, and it can be used under low temperature conditions. Polypropylene straws with good heat resistance are not biodegradable
