Environment-friendly bio-based high-toughness material for 3D-printed garage kit and preparation method of environment-friendly bio-based high-toughness material

Abstract

The invention provides an environment-friendly bio-based high-toughness material for a 3D-printed garage kit and a preparation method of the environment-friendly bio-based high-toughness material. Theenvironment-friendly bio-based high-toughness material comprises the following components in parts by weight: 30-50 parts of castor oil, 10-30 parts of polyhexamethylene adipate polyol, 15-35 parts of toluene diisocynate, 5-10 parts of hydroxyethyl methacrylate, and 10-20 parts of an active diluent. According to the environment-friendly bio-based high-toughness material for the 3D-printed garagekit, bio-based castor oil is adopted as a raw material, so the prepared high-toughness material is biodegradable, environmentally-friendly and free of pollution; the castor oil and polyhexamethylene adipate polyol are matched for use, so the hardness of the material is guaranteed, the flexibility of the material is improved, and a product prepared from the material is not easy to damage; and the high-toughness material is simple in formula and structure, and the product is good in stability and enhances the use feeling of customers.

Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to an environmentally friendly bio-based high-toughness material for 3D printing figures and a preparation method thereof. Background technique [0002] 3D printing figure is a figure made and colored by 3D printing technology, and produced through digital model technology. The figure produced by this method has high manufacturing precision, beautiful appearance, and greatly reduces the manufacturing cost. [0003] In the prior art, the materials used to make figures are generally PVC or PMMA, but both are non-degradable, easily cause a large amount of white pollution, and are poor in environmental protection. And the former is also called soft material. Due to the requirement of plasticity in the production process, a large amount of plasticizer will be added, and the plasticizer will be precipitated when the figure prepared in the later stage encounters high temperat...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the materials used to make figures are generally PVC or PMMA, but neither of them can be degraded, which is easy to cause a lot of white pollution, and the environmental protection is poor.

And the former is also called soft material. Due to the requirement of plasticity in the production process, a large amount of plasticizer will be added, and the plasticizer will be precipitated when the figure prepared in the later stage encounters high temperature, and the product stability is poor; while At low temperature, it will cause changes in hand feel and affect sensory quality

The latter is very brittle, and the figures prepared using it will cause permanent damage when they encounter a collision or fall, which cannot be repaired.
