Abstract

The invention relates to a natural aromatic foam material and a preparation method, belonging to the technical field of foam materials and preparation methods. The natural aromatic foam material is prepared from a raw material polypropylene, and is characterized by also being prepared from natural aromatic plant materials and another additive. The raw material and materials are weighed in parts by weight: 8-20 parts of natural aromatic plant powder, 50-80 parts of the raw material polypropylene, and 1-10 parts of the other additive, wherein the other additive is a mixture of one or more of EPDM, modified talcum powder, monoglyceride and stearic acid. The natural aromatic plant powder is selected and is mixed with polypropylene to prepare a master batch, so as to prepare polypropylene-plant compound microporous plastic beads or sheets; the foam material can give out natural fragrance, and can be widely used in fields such as household consumer products and craft toys, the added value of the plastic foam material can be improved, and the use ratio of the natural aromatic plant can be improved.

Description

technical field [0001] The invention belongs to the technical field of foaming materials and preparation methods, and in particular relates to a natural aromatic foaming material and a preparation method. Background technique [0002] Combining flavors and fragrances with plastics to make new functional plastics is a hot spot in the plastics processing industry. This scented plastic product not only retains the original rigidity and strength of plastic, but also emits a fragrance when used, giving people a fresh, comfortable and refreshing feeling, and increasing the added value of plastic products. However, most of the existing scented plastics use PVC as the base material, which has the hazards of plasticizers; general flavors and fragrances will lose their flavor or become invalid when processed at >150°C; the chemical foaming process has disadvantages such as long-term high-temperature molding and harmful residues. Plastic foam material has good elasticity, light wei...
