Preparation method of biodegradable tableware

Abstract

The invention aims to provide a preparation method of biodegradable tableware. The technical scheme is as follows: the method comprises the following steps: dissolving a certain amount of guar gum in water, adding a certain proportion of beta-mannase, and stirring for 0.5-2 hours; and adding a plasticizing agent, a latex agent, an accelerator and the like, stirring for 5-10 minutes, thoroughly mixing uniformly, and processing to obtain the biodegradable tableware.

Description

technical field

[0001] The invention relates to a preparation method of biodegradable materials, in particular to a preparation method of biodegradable tableware. Background technique

[0002] Since the 1950s, with the continuous expansion of the petroleum industry, plastic, as a synthetic polymer material, has become a necessity closely related to people's lives.

[0003] The increasing number of single-use plastic products has deteriorated the soil environment and threatened human survival. Research on biodegradable products is imperative.

[0004] The existing biodegradable biomaterial technology has obvious performance differences due to different types, sources and processing techniques. It is difficult to control the quality stability, and the process is complicated and difficult to gelatinize. Contents of the invention

[0005] The purpose of the present invention is to provide a preparation method of biodegradable tableware to overcome the defects in the prior a...

Examples

Embodiment 1

[0014] Get one weight part of guar gum and dissolve it in 0.5 weight parts of water, add 1% β-mannanase, stir for 0.5 hour; Minutes, fully mixed evenly, and processed to obtain the biodegradable tableware.

Embodiment 2

[0016] Get one weight part of guar gum and dissolve it in 0.5 weight parts water, add 1.5% beta-mannanase, stir for 1 hour; 8 minutes, fully mixed evenly, and processed to obtain the biodegradable tableware.

Embodiment 3

[0018] Get the guar gum of 1 weight part and be dissolved in 0.5 weight part water, add 2% beta-mannanase, stir 1.5 hours; Minutes, fully mixed evenly, and processed to obtain the biodegradable tableware.
