Abstract

The invention provides a straw 3D printing consumable and a preparation method thereof. The formula includes the following raw materials in mass percentage: 40 to 69 percent of polylactic acid, 30 to 59 percent of straw powder, 0 to 5 percent of a compatilizer, and 0.2 to 3 percent of other additives. Straws, a crop byproduct, are fully utilized by the straw 3D printing consumable for surface modification, and the degradable material polylactic acid is added for melt blending. Compared with the prior art, the 3D printing material provided by the invention has stable performances, can replace common 3D plastic consumables in 3D printing, is non-toxic, low-carbon and environment-friendly, and has superior comprehensive performances, thereby achieving considerable economic value and broad market prospects.

Description

technical field [0001] The invention belongs to the production field of plastic particles, and in particular relates to a straw 3D printing consumable and a preparation method thereof. Background technique [0002] Most of the existing 3D printing consumables are based on high molecular polymers extracted from petroleum, for example: ABS, PP, PE, nylon, HIPS, PC are non-degradable materials, and waste 3D printing materials or products will cause huge damage to the ecological environment. The burden of developing a degradable 3D printing material that can make full use of abandoned crops can not only make full use of the by-product straw of crops, but also be used as a degradable material, so that the printed material will not cause white pollution to the ecological environment due to discarding . [0003] Patent CN102153801 A discloses a straw plastic and its production method. Publication date: August 17, 2011. It discloses the copolymerization of straw materials with poly...
