Abstract

The invention discloses a multi-fiber composite degradable environment-friendly tableware. The tableware is prepared from the following raw materials in parts by weight: 70 to 90 parts of isophorone diisocyanate, 100 to 120 parts of polycarbonate diol, 1 to 2 parts of butyltin mercaptide, 0.3 to 0.7 part of chain extender, 40 to 50 parts of brucite fiber, 20 to 30 parts of sisal fiber, 3 to 4 parts of dicumyl peroxide, 50 to 60 parts of dimethyl carbonate, 20 to 26 parts of stearic acid, 20 to 30 parts of triethanolamine, 1 to 2 parts of p-toluene sulfonic acid and 2 to 4 parts of silane coupling agent kh550. The tableware material disclosed by the invention does not contain toxic and harmful substances, and is good in environmental protection property, high in finished product toughness, good in antibacterial activity and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of environment-friendly tableware, and in particular relates to a multi-fiber composite degradable environment-friendly tableware and a preparation method thereof. Background technique [0002] At present, the raw materials of commonly used environmentally friendly plastic tableware mainly include polymer materials such as polyethylene, polyethylene terephthalate, polycarbonate, and polystyrene. In the process of processing plastic tableware, due to the use of polyethylene , Polyethylene terephthalate, polycarbonate, polystyrene and other polymer materials have poor mechanical properties, and the materials used are not pure polymer materials, and fillers, plasticizers, lubricants need to be added , stabilizers or other additives can be made into plastic tableware products with good performance. The environmental protection of this kind of tableware products is poor, and some plasticizers contain toxic and harmful sub...
