Problems solved by technology

[0002] The requirements for the ecological environment are constantly improving. White pollution can be replaced by environmentally friendly materials, but it cannot be completely replaced. The appearance of the new generation of full-starch fully degradable lunch boxes can protect the ecological environment and the duplication of resources. Utilization, but the fully degradable technology is not mature enough, and the equipment is expensive and difficult to obtain, so that the fully degradable lunch box material cannot be realized quickly. Using the traditional lunch box preparation process plus fully degradable starch materials, the materials complement each other and the equipment Improvements make biodegradable lunch boxes more accessible

Embodiment 1

[0041] A new material for lunch boxes that can be automatically degraded, such as Figure 1-Figure 4 It consists of the following parts by weight, 60 parts of corn starch, 10 parts of potato starch, 20 parts of straw powder, 2 parts of fusion agent, 15 parts of polyglycolic fat, 15 parts of polylactic acid, and 10 parts of additives; the preparation method of the new material includes The following steps:

[0042] Step 1. Raw materials are mixed and stirred:

[0043] S1. Grind cornstarch and potato starch on a ball mill. The ground cornstarch and potato starch are vibrated and screened on a 200-mesh vibrating sieve respectively. The cornstarch and potato starch that have not passed the screening continue to be ground and screened again, and so on; The powder is ground on a ball mill, and the ground straw powder is vibrated and screened on a 100-mesh vibrating sieve, and the straw powder that has not passed the screen continues to be ground and screened, and this is repeated; ...

Embodiment 2

[0062] A new material for a lunch box that can be automatically degraded, consisting of the following parts by weight: 55 parts of corn starch, 8 parts of potato starch, 15 parts of straw powder, 1 part of fusion agent, 10 parts of polyethylene glycol fat, 10 parts of polylactic acid, and 5 parts of additives ; The preparation method of this automatically degradable lunch box new material is as in Example 1.

Embodiment 3

[0064] A new self-degradable lunch box material, which consists of the following parts by weight: 60 parts of corn starch, 5 parts of potato starch, 10 parts of straw powder, 1.5 parts of fusion agent, 10 parts of polyethylene glycol fat, 15 parts of polylactic acid, and 10 parts of additives ; The preparation method of this automatically degradable lunch box new material is as in Example 1.

Abstract

The invention discloses a novel automatically-degradable material of meal boxes and a preparation method of the novel automatically-degradable material of the meal boxes. The novel automatically-degradable material is prepared from, by weight, 50-60 parts of corn starch, 5-10 parts of potato starch, 10-20 parts of straw powder, 1-2 parts of a fusion agent, 10-15 parts of polyethylene ethanol ester, 10-15 parts of polylactic acid and 5-10 parts of additives. The material is prepared by steps of mixing and stirring, mixture distribution, hot-pressing molding, trimming and inspection, and waterproof sterilization. By advantageous complementation of corn starch and potato starch, adding of straw powder with natural fibers to make more than 90% of materials of the meal boxes completely degradable and reduction of chemical additives, the ecological environment is effectively protected, and product cost is saved.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a new material for an automatically degradable lunch box and a preparation method thereof. Background technique [0002] The requirements for the ecological environment are constantly improving. White pollution can be replaced by environmentally friendly materials, but it cannot be completely replaced. The appearance of the new generation of full-starch fully degradable lunch boxes can protect the ecological environment and the duplication of resources. Utilization, but the fully degradable technology is not mature enough, and the equipment is expensive and difficult to obtain, so that the fully degradable lunch box material cannot be realized quickly. Using the traditional lunch box preparation process plus fully degradable starch materials, the materials complement each other and the equipment Improvements in biodegradable lunch boxes are easier to ac...
