Adhesive for forming and processing of 3D (three-dimensional) printing

Abstract

The invention relates to an adhesive for forming and processing of 3D (three-dimensional) printing. The adhesive is prepared from the following materials in parts by mass: 25% to 40% of resin, 3.5% to8% of plant fiber, 3.5% to 8% of nylon fiber, 3.5% to 8% of graphene fiber, 0 to 5% of silicone oil, 1.5% to 4.5% of accelerant, 2.3% to 7.1% of filling agent, 1.5% to 4.5% of curing agent, 4% to 12%of crosslinking agent, 3.5% to 8.5% of coupling agent, 0.5% to 1.5% of toughener, and the balance of thinner. The adhesive has the advantages that the obtaining of production raw materials is easy, the cost is low, the pollution and toxicity are low, the production efficiency is effectively improved, and the production cost is reduced; the good adhering ability and universality are realized, therequirements of forming in 3D printing of multiple types of metal, non-pole non-metal and macromolecular polymers can be effectively met, the flexibility in use of the adhesive is greatly improved, and the application range is widened.

Description

Technical field [0001] The invention relates to an adhesive for molding processing for 3D printing, belonging to the technical field of 3D printing. Background technique [0002] At present, in the 3D printing and forming processing operations, it is necessary to evenly coat a layer of adhesive on the worktable surface of the workpiece processing and forming to meet the needs of the workpiece processing and forming operations. However, in actual use, the currently used adhesive Adhesives often contain certain polluting and toxic raw materials, so it is easy to cause environmental pollution during production and use, and cause the safety and reliability of processed workpieces to be affected. At the same time, the current adhesives are in use due to the use of Due to the raw material formulation factors, a type of adhesive can only meet the processing operations of a single type of workpiece, and cannot effectively meet the needs of processing operations of metals, inorganic non-m...

Problems solved by technology

[0002] At present, in the 3D printing and molding operations, it is necessary to evenly coat a layer of adhesive on the work surface of the workpiece processing and molding to meet the needs of the workpiece processing and molding operations. However, in actual use, the currently used adhesive The adhesives often contain certain polluting and toxic raw materials, so the production, preparation and use are likely to cause environmental pollution, and cause the safety and reliability of the processed workpiece to be affected. At the same time, the current adhesives are in use. Due to the raw material formula factors, a class of adhesives can only meet the processing operations of a single type of workpiece, and cannot effectively meet the processing needs of metals, inorganic non-metals, and high molecular polymers at the same time. Therefore, the use of flexibility and The reliability is relatively poor, and it also causes the current 3D printing operation versatility, reliability and flexibility to be greatly affected. Therefore, in response to this problem, it is urgent to develop a new adhesive to meet the needs of actual use.
