Problems solved by technology

[0004] Through investigation and research, it is found that the existing polymer materials in the market have different uses. During the development process, polymerization and modification of several different materials are usually used to ensure the final use effect. The proportion of materials that can be used for food contact is very small. Manufacturers Considering the appearance design, the final product often relies on color masterbatches and toners of various colors to color, resulting in various tests exceeding the standard and food contact inspection failing
Moreover, the vast majori

Example Embodiment

[0071] Examples 1-5:

[0072] The components and proportions of Examples 1 to 5 are calculated by mass percentage (%), as shown in the following table.

[0073] Table 1 Example 1-5 components and ratio

[0074]

[0075] The preparation methods of the degradable food contact composition polymerized by coffee grounds of Examples 1-5 are all carried out according to the following steps, which include:

[0076] Primary drying step: drying polybutylene succinate, polybutylene succinate, polybutylene terephthalate and polylactic acid once at a temperature of 70-80°C and a time of 0.5 -1.5h, the recovered coffee grounds are dried for the second time. The temperature of the second drying is 70-80℃ and the time is 4-6h. After the second drying, the moisture content of the coffee grounds is less than 2%. Backup

[0077] Mixing steps: Put the dried polybutylene succinate, polybutylene adipate / terephthalate, polylactic acid and coffee grounds, talc powder, and aluminate coupling agent into the...

Abstract

The invention discloses a coffee residue polymerized degradable food contact composition and a preparation method thereof. The composition is prepared from, by mass, 28-70% of polybutylene succinate,15-30% of polyadipic acid/polybutylene terephthalate, 3-10% of polylactic acid, 10-25% of coffee residues, 1.5-6% of talcum powder and 0.5-1% of an aluminate coupling agent, wherein the sum of mass percentages is 100%. Compared with existing similar food contact material products on the market, the composition which meets the food contact requirement has advantages of high degradability, safety, nontoxicity and high practicality.

Description

technical field [0001] The invention relates to a food contact polymer material, in particular to a degradable food contact composition polymerized with coffee grounds and a preparation method thereof. Background technique [0002] Coffee is a commodity with a global trading volume second only to crude oil. In 2016, the global coffee production was about 930 million tons. China’s coffee consumption accounted for a small proportion, with an average annual average of about 40,000 tons, but it increased steadily at a rate of 15% per year. The prospects are promising. The freshly ground coffee, instant coffee and other coffee drinks we often drink are brewed after the coffee beans are ground into granules or powder, and 70% of the original mass of "coffee grounds" will remain after extraction. According to the existing practice, these coffee grounds will be treated as kitchen waste landfill or incineration. According to the incomplete survey and statistics in the early stage, i...
