Abstract

The invention discloses an environment-friendly plastic bag. The plastic bag is made of the following raw materials in parts by weight: 30-40 parts of acrylic acid, 8-18 parts of straw fiber, 12-16 parts of modifying filler, 3-5 parts of vegetable gum composition, 2-6 parts of a plasticizer, 5-10 parts of polyurethane, 1-3 parts of antibacterial oil, 2-4 parts of alkaloid composition, 1-3 parts ofa dispersant, 1-4 parts of an antioxidant and 5-9 parts of glycerin. Acrylic acid is modified with the modifying filler, so that strength of the plastic bag is effectively ensured, degradability of the plastic bag is improved, and degradation time is shortened. The wood-plastic composite prepared from the modified straw fiber has excellent tensile strength, impact strength and bending strength, and is beneficial to practical application and development of the straw wood-plastic composite. The alkaloid composition added adopts a mixture of leonurine and colchicine which are extracted from natural plants to replace traditional toxic organic amine, does not contain toxic substances, and is healthy and environmentally friendly.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an environment-friendly plastic bag. Background technique [0002] At present, China's annual output of plastics is 30 million tons, and its consumption is more than 60 million tons. The annual output of plastics in the world is 1 billion tons. If calculated according to the annual plastic waste of 15%, the annual plastic waste in the world is 150 million tons, and the annual plastic waste in China is more than 10 million tons. The proportion accounts for 40%. Such a large amount of waste plastics are buried in the ground as garbage, which will undoubtedly bring greater pressure to the lack of arable land. While plastics bring convenience to people's lives, they also bring troubles to the environment that are difficult to deal with. People call the disasters brought by plastics to the environment "white pollution". Plastic bags do bring convenience to people's lives, but the convenience...
