preparation example Construction

[0012] The invention provides a preparation method of 3D printing powder, the preparation method comprising: (1) polyvinyl alcohol, methyl methacrylate, butyl acrylate, β-hydroxyethyl methacrylate, initiator and mixed with water, filtered after heating and reacting, to obtain a hydroxyacrylic acid copolymer resin; (2) drying and grinding the hydroxyacrylic acid copolymer resin to obtain the 3D printing powder; wherein, relative to 100 parts by weight of polyvinyl alcohol, the The consumption of methyl methacrylate is 30-50 parts by weight, the consumption of butyl acrylate is 20-30 parts by weight, and the consumption of β-hydroxyethyl methacrylate is 10-18 parts by weight, so The dosage of the initiator is 2-5 parts by weight, and the dosage of the water is 60-90 parts by weight.

[0013] In order to make the prepared 3D printing powder have more excellent flexibility and water resistance, in a preferred embodiment of the present invention, relative to 100 parts by weight of ...

Embodiment 1

[0022] 100g polyvinyl alcohol, 35g methyl methacrylate, 23g butyl acrylate, 14g-beta-hydroxyethyl methacrylate, 3.5g benzoyl peroxide and 70g water are mixed, and heating reaction (the temperature of heating reaction is 60 ℃, the heating reaction time is 30min), and then filter to obtain the hydroxyacrylic acid copolymer resin; dry the hydroxyacrylic acid copolymer resin (the drying temperature is 40 ℃, and the drying time is 1h), and grind to obtain the hydroxyacrylic acid copolymer resin 3D printing powder (particle size 50μm).

Embodiment 2

[0024] Mix 100g polyvinyl alcohol, 45g methyl methacrylate, 27g butyl acrylate, 16g-β-hydroxyethyl methacrylate, 4.5g lauroyl peroxide and 80g water, and heat the reaction (the temperature of the heating reaction is 70°C , the heating reaction time is 40min) and then filtered to obtain the hydroxyacrylic acid copolymer resin; the hydroxyacrylic acid copolymer resin is dried (the drying temperature is 50°C, and the drying time is 2h), and the 3D acrylic acid copolymer resin is obtained after grinding. Print powder (particle size 80μm).

Abstract

The invention discloses 3D (three-dimensional) printing powder and a preparation method thereof. The preparation method comprises the following steps of mixing polyvinyl alcohol, methyl methacrylate, butyl acrylate, beta-hydroxyethyl methacrylate, an initiator and water; performing heating reaction; then, performing filtering to obtain hydroxy acrylic copolymer resin; drying and grinding the hydroxy acrylic copolymer resin to obtain the 3D printing powder. The problems that the ordinary 3D printing material can easily change color and become loose in the humid environment, and the flexibility is low are solved.

Description

technical field [0001] The present invention relates to 3D printing powder, in particular to 3D printing powder and a preparation method thereof. Background technique [0002] At present, 3D printing molding equipment at home and abroad are relatively mature, but there is a lack of high-performance printing materials suitable for different purposes, and the price is relatively high, which directly leads to high cost of 3D printing, lengthy manufacturing process and poor product performance, which restricts its development. . Ordinary 3D printing materials are prone to discoloration, looseness, and poor flexibility in humid environments. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a kind of 3D printing powder which is not easy to change color and loose in humid environment, and has high flexibility and its preparation method. Contents of the invention [0004] The purpose of the present invention is to provide a 3D printing...
