Problems solved by technology

Limited by the strength and bonding performance of the material itself, the printed product is not strong enough and is easy to break and crack
Due to the high thermal expansion coefficient of the existing materials, the surface of the product prepared by the "layer-by-layer accumulation" method is usually due to the gap between layers formed by the shrinkage of the material, and the product has a low finish, so it needs to be polished and polished. , leading to the inability of 3D printing to be applied to production on a large scale
In addition, the gaps formed due to material shrinkage are also prone to stress points and stress cracks, which affect the strength of products prepared by 3D printing.

Abstract

The invention discloses a PBT / PC alloy material. The PBT / PC alloy material comprises, by weight, 6.5-42.6 parts of PBT, 70-90 parts of PC and 0.2-0.7 part of ester exchange inhibitor. The PBT / PC alloy material has the advantages that the ester exchange inhibitor is specially added, the ester exchange inhibitor can effectively control the ester exchange reaction, that is to say, the occurrence frequency and probability of the ester exchange reaction at various positions in the PBT / PC alloy material are allowed to be close, the PBT / PC alloy material uniform in texture is obtained, stress points with extremely low density are eliminated to increase product strength, and the PBT / PC alloy material can be applied to the fast forming technology of the precise parts of electronic products.

Description

technical field [0001] The invention relates to a PBT / PC alloy material, in particular to a PBT / PC alloy material and a preparation method and application thereof. Background technique [0002] Rapid prototyping technology, also known as "3D printing" or "rapid prototyping manufacturing technology" (Rapid prototyping manufacturing technology), is a high-tech manufacturing technology based on material accumulation method, using three-dimensional CAD data, through a rapid prototyping machine, layer by layer material Methods stacked into physical prototypes. This method has many advantages. Its manufacturing is fast, it can fully reproduce the three-dimensional effect, and the product design and mold production can be synchronized to realize the integration of design and manufacturing. At the same time, it uses a wide range of materials. The types of materials used in various 3D printers are : Resin, nylon, plastic, paraffin, paper, metal or ceramic powder, etc. The most wide...
