Problems solved by technology

However, because carbon fiber is a brittle material with poor toughness, the toughness of the obtained selective laser sintered parts is greatly reduced, which cannot meet the performance requirements of some end products.
And because the fiber has a strong stimulating effect on the skin of the human body, it is difficult to be widely used in practice.

Embodiment 1

[0033] A preparation method for a toughened material for SLS, comprising the following steps:

[0034] Step 1, take each material for subsequent use, wherein each component mass percent is respectively: nylon 6 powder 98%, fumed silicon dioxide 0.5%, nickel titanium yellow 1%, antioxidant 9228 0.5%, get 15% Nylon resin is mixed with fumed silica, antioxidant 9228 and nickel-titanium yellow and stirred with a high-speed stirrer to ensure that the fumed silica is completely crushed and fully mixed to obtain a powder-inducing material; among them, the particle size of nylon 6 powder is 20 μm, The particle size of the nickel titanium yellow powder is 2 μm.

[0035] Step 2, using a V-shaped mixer to fully stir and mix the powder-inducing material and the remaining nylon resin for 30 minutes to obtain a toughened material.

Embodiment 2

[0037] A preparation method for a toughened material for SLS, comprising the following steps:

[0038] Step 1, take each material for subsequent use, wherein the mass percentages of each component are respectively: nylon 1212 powder 95%, fumed silicon dioxide 0.1%, nickel titanium orange 3%, antioxidant 9228 0.9%, get 18% Nylon resin is mixed with fumed silica, antioxidant 3026 and nickel-titanium orange and stirred with a high-speed stirrer to ensure that the fumed silica is completely broken and mixed thoroughly to obtain powder-inducing materials; among them, the particle size of nylon 1212 powder is 35 μm, The particle size of the nickel titanium yellow powder is 50 μm.

[0039] Step 2, using a V-shaped mixer to fully stir and mix the powder-inducing material and the remaining nylon resin for 45 minutes to obtain a toughened material.

Embodiment 3

[0041] A preparation method for a toughened material for SLS, comprising the following steps:

[0042] Step 1. Weigh each material for later use, wherein the mass percentages of each component are: 95% of nylon 12 powder, 1% of fumed silica, 2.7% of nickel titanium yellow, antioxidant 9228 and antioxidant 3026 according to the mass ratio of 1 : 1 mixed antioxidant 0.3%, glass fiber 1%, get 18% nylon resin and fumed silicon dioxide, antioxidant 9228, antioxidant 3026 and nickel-titanium yellow to mix and utilize high-speed stirrer to stir, ensure The fumed silica is completely crushed and fully mixed to obtain powder-inducing materials; wherein, the particle size of the nylon 12 powder is 80 μm, and the particle size of the nickel titanium yellow powder is 80 μm.

[0043] Step 2, using a V-shaped mixer to fully stir and mix the powder-inducing material and the remaining nylon resin for 50 minutes to obtain a toughened material.

Abstract

The invention relates to the technical field of SLS toughening materials, in particular to a toughening material for SLS and a preparation method thereof. A toughening material for SLS, consisting of the following raw materials in mass percentage: nylon resin 95-98%, flow aid 0.1-1%, antioxidant 0.3-1.5%, toughening modified material 0.5-4% , the total mixing percentage of the above components is 100%. The toughened material is prepared by mixing, and the impact strength and elongation at break are greatly improved, which can more meet the performance of selective laser sintering molded parts for direct use as end products. Requirements, simple preparation process, environmental protection and no pollution.

Description

technical field [0001] The invention relates to the technical field of SLS toughening materials, in particular to a toughening material for SLS and a preparation method thereof. Background technique [0002] Selective Laser Sintering (SLS) is a widely used rapid prototyping technology at present. The principle of the forming process is: based on the digital model file, first establish the computer three-dimensional model of the target part, and then use layered The software slices the 3D model to obtain the data information of each processing level. Under the control of the computer, according to the slice level information, the laser beam is used to scan and sinter the heat-fusible powder material layer by layer, and finally complete the processing and manufacturing of the target parts. Its core is the combination of digitalization, intelligent manufacturing and material science. SLS technology can be applied to a wide range of materials, including polymers, metals and cer...
