Embodiment 1
[0032] Environmentally friendly self-aromatic and continuously volatile polypropylene, which is prepared from the following components by weight:
[0033] 75 parts of random polypropylene,
[0034] 15 parts of modified expanded vermiculite,
[0035] 2 parts of polypropylene grafted maleic anhydride,
[0036] Fragrant masterbatch 10 parts,
[0037] 0.15 parts of silane coupling agent,

Abstract
The invention discloses an environment-friendly polypropylene material with continuous fragrance and a preparation method of the environment-friendly polypropylene material. The environment-friendly polypropylene material with continuous fragrance is prepared from components in parts by weight as follows: 70-80 parts of polypropylene, 10-15 parts of modified expanded vermiculite, 2.0-3.0 parts ofpolypropylene grafted maleic anhydride, 3-10 parts of fragrant masterbatch, 0.1-0.3 parts of a silane coupling agent, 0.1-0.2 parts of polyacetamide, 0.2-1 part of an antioxidant and 0.5-1 part of a lubricant. The defects that fragrance of the traditional fragrant material cannot last for a long time and essence contains toxins are overcome, the technological flow for foaming and pore opening of aself-fragrant material is simplified, and little influence is produced on material performance. The prepared polypropylene material has the characteristics of environmental protection, continuously emitted self-fragrance and the like, and half-year weight loss ratio of a fragrance in a standard environment is not higher than 5%; the polypropylene material can be widely applied to the fields of home appliance functional materials, automobile decorative materials, children's toys and the like.
Description
technical field [0001] The invention relates to the technical field of polymers, in particular to an environment-friendly polypropylene material with persistent fragrance and a preparation method thereof. Background technique [0002] With the development of the economy, people have higher and higher requirements for environmental protection, safety, comfort, etc., and pay more attention to the ecological environment and the value of life. Most of the existing aromatic plastics are made by in-situ polymerization. Due to the limitation of materials, the materials contain toxic and harmful substances such as formaldehyde and stupid. As people pay more and more attention to health, environment and ecological protection, people's environmental protection standards and environmental standards for materials used are becoming increasingly strict. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of environment-fri...
