Problems solved by technology

However, the main component of existing disposable plastic tablecloths is polyethylene, which takes a long time to degrade in nature after being discarded, causing environmental pollution
On the other hand, because it is discarded after one use, in order to save costs, the existing disposable plastic tablecloths are relatively thin in thickness, insufficient in strength, and poor in flexibility, resulting in easy breakage when pulled or folded

Abstract

The invention discloses a disposable degradable table cloth. The invention is characterized in that the disposable degradable table cloth comprises the following raw materials in parts by weight: 20-25 parts of polyethylene, 50-75 parts of superfine calcium carbonate, 2-5 parts of hollow glass microsphere, 0.1-0.5 part of photodegradation agent, 0.5-2 parts of degradation induction period regulator and 0.1-0.5 part of calcium tetrahydrophthalate. The invention also discloses a production technique of the disposable degradable table cloth. The calcium carbonate loading level of the table cloth is 50% or above, thereby saving the cost, implementing quick degradation in the natural environment and keeping higher comprehensive properties (especially strength and flexibility); and the table cloth can not easily break when in use.

Description

technical field [0001] The invention relates to the technical field of tablecloths, in particular to a formula and a production process of a disposable degradable tablecloth. Background technique [0002] Tablecloth, also known as tablecloth, is a relatively common table cloth, especially on the dining tables of high-end restaurants. According to the different materials, tablecloths can be divided into two categories: plastic and textile. Among them, plastic tablecloths are divided into disposable and reusable. Reusable tablecloths need to be cleaned after each use. In places with a lot of use, such as hotels and restaurants, the cleaning work requires a lot of manpower and resources. Disposable plastic tablecloths are easy to use and hygienic. But the main component of existing disposable plastic tablecloth is polyethylene, and the degradation time in nature after throwing away is long, causes environmental pollution. On the other hand, because they are discarded after ...
