Embodiment 1

[0039] In parts by weight, add Twax-05064 parts and BYK-P1041 parts into a container containing 40 parts of acrylic monomers, disperse at high speed for 20-30 minutes, and then add 50 parts of linear alkane polyurethane acrylic resin, 2 parts of benzoin diethyl ether, 1 part of phthalocyanine blue, 1 part of BYK-0561, 1 part of BYK-0711, disperse at high speed for 10-15 minutes for each material added, after the last material is added, continue to disperse at high speed for 30 minutes until the liquid is uniform, and then The liquid mixture is poured into a sand mill for grinding to obtain a wax-containing 3D printing light-curing casting resin.

Embodiment 2

[0047] In parts by weight, add 1 part of PEW-05111 part and 1 part of BYK-P104S into a container containing 15 parts of cyclotrimethylolpropane methylal acrylate monomer, disperse at high speed for 20-30 minutes, and then pour them into the container according to the proportion Add 80 parts of polyester acrylate, 2 parts of 1-hydroxycyclohexyl phenyl ketone, 0.2 parts of permanent orange, 0.4 parts of BYK-501A, and 0.4 parts of BYK-1410. After one material is added, the whole continues to be dispersed at high speed for 30 minutes until the liquid is uniform, and then the liquid mixture is poured into a sand mill for grinding to obtain a wax-containing 3D printing light-curing casting resin.

[0048] Similar to Example 1, the viscosity of the wax-containing 3D printing light-curing casting resin prepared in this example is 320cps@25°C, the Shore hardness is 60D (according to ASTM DIN EN ISO 868 standard), and the ash content is 0.048% (according to GB / T14235.3-1993 standard), t...

Embodiment 3

[0050] In parts by weight, add Clanrant CERIDUST 36101 parts and BYK-P1050.01 parts into a container containing 60 parts of cycloacrylamide monomer, disperse at high speed for 20-30 minutes, and then add polyester acrylate 30 parts in proportion to the container 1 part, 8 parts of benzophenone, 0.79 part of phthalocyanine red, 0.1 part of BYK-501A, 0.1 part of BYK-0720. Each material added is dispersed at high speed for 10-15 minutes. After the last material is added, the whole continues to disperse at high speed for 30 minutes to The liquid is uniform, and then the liquid mixture is poured into a sand mill for grinding to obtain a wax-containing 3D printing photocurable casting resin.

[0051] Similar to Example 1, the viscosity of the wax-containing 3D printing light-curing casting resin prepared in this example is 382cps@25°C, the Shore hardness is 52D (according to ASTM DIN EN ISO 868 standard), and the ash content is 0.040% (according to GB / T14235.3-1993 standard), the li...

Abstract

The invention discloses wax-containing 3D printing light-cured cast resin and a preparation method thereof. The wax-containing 3D printing light-cured cast resin comprises the following components inparts by weight: 30-80 parts of oligomer resin, 15-60 parts of a reactive diluent, 1-10 parts of a photoinitiator, 1-10 parts of micro-powder wax, 0.1-5 parts of an organic pigment, 0.01-2 parts of adispersing agent, 0.1-5 parts of a defoaming agent and 0.1-5 parts of a flatting agent. The wax-containing 3D printing light-cured cast resin disclosed by the invention has the multiple advantages oflow viscosity, excellent mechanical property, low ash content, small linear shrinkage rate and the like, and can effectively ensure the dimensional precision and clean and smooth appearance of a casting. The invention provides the light-cured material with high printing precision, rapid casting and stable performance for the field of 3D printing and casting, greatly expands the advantages of a laser rapid prototyping technology in the field of casting, and remarkably improves the market competitiveness of products.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a wax-containing 3D printing light-curing casting resin and a preparation method thereof. Background technique [0002] Precision casting is widely used in mechanical electronics, aerospace, marine, petrochemical, biomedical and other fields due to its multiple advantages such as casting complex structures, excellent surface quality, high dimensional accuracy, and less post-processing procedures. Laser rapid prototyping technology is a high-tech manufacturing technology based on stacking and additive processing that originated in the 1980s. It has the characteristics of high forming precision, high material utilization rate and complex structure processing. Combining the respective advantages of the two, combining the casting process with digital manufacturing, using laser rapid prototyping to make prototype investment patterns for precision casting parts, and then making she...
