Problems solved by technology

[0002] Ordinary photosensitive resins are irritating to the skin of the human body, which means that they cannot have direct contact with the skin; if they adhere to the skin, itching, burning, peeling, tingling, even redness
Therefore, it is necessary to wear disposable protective gloves when performing printing-related operations, but after a long time, the photosensitive resin will still penetrate the gloves and cause irritation to the fingers and other parts, resulting in the above phenomenon
As a result, the following series of problems are brought about: the disposal of waste photosensitive resin is difficult, and it is easy to pollute the surrounding facilities and environment, causing pollution; protective gloves need to be replaced frequently, which is inconvenient to operate, and a large number of contaminated gloves, rags, etc. are also irritating. polluted environment
Nevertheless, the irritation problem of free radical photocurable type photosensitive resins is still prevalent in the field of 3D printing and has not been solved

Embodiment 1

[0033] Example 1 Transparent photosensitive resin

[0034] Polyurethane acrylate (grade: Changxing 61362) 70 parts, 27 parts of triapropylene glycol diacrylate, 2,4,6-trimethylbenzoyl-diphenyl phosphine (TPO) 2.9 parts, 4 of defoamer. Dispersion speed 1200 rpm, dispersion time is 60 minutes. The resin is small to skin irritation, printing various models on the 3D printer of the vertical direction, which is good.

Embodiment 2

[0035] Example 2 White photosensitive resin

[0036] Polyurethane acrylate (grade: Changxing 6172-1) 70 parts, 26 copies of acryloyl morpholine, 2,4,6-trimethylbenzoyl-diphenyl oxide (TPO) 2.9 parts, 4 of antifoaming agent 1 white pulp. Dispersion speed 1200 rpm, dispersion time is 60 minutes. The resin is small to skin irritation, printing various models on the 3D printer of the vertical direction, which is good.

Embodiment 3

[0037] Example 3 Black photosensitive resin

[0038] Polyurethane acrylate (grade 6150-100) 71 parts, 26.9 copies of acrylate, 2,4,6-trimethylbenzoyl-diphenyl oxide (TPO) 1.9 parts, defoamer 0.1 parts , 0.1 parts of black pulp. Dispersion speed 1200 rpm, dispersion time is 60 minutes. The resin is small to skin irritation, printing various models on the 3D printer of the vertical direction, which is good.

Abstract

The invention discloses low-irritation photosensitive resin, which is prepared from the following components in parts by weight: 70-98 parts of an acrylate oligomer, 0-29 parts of a low-irritation monomer, 0.5-5 parts of a free radical photoinitiator, 0.05-0.2 parts of a defoaming agent and 0-1 part of color paste. The resin prepared according to the invention has the advantages of low irritation to human skin, low odor, moderate viscosity and good printing effect, and is suitable for the field of 3D printing.

Description

Technical field [0001] The present invention relates to a low stimulating photosensitive resin technology field. Background technique [0002] Ordinary photosensitive resins have certain irritation to the human skin, which is expressed as direct contact with the skin; if it is adhered to the skin, the contact portion will appear itchy, burning, rt, stinging after the time is long. Even redness and other phenomena. Therefore, it is necessary to wear disposable protective gloves when printing related operations, but the photosensitive resin will still penetrate the gloves to the finger and other parts, resulting in the above phenomenon. This brings the following series of questions: abandoned photosensitive resin is difficult, easy to tarnish around facilities and environment, causing pollution; protective gloves need frequent replacement, inconvenient operation, producing a large amount of warbits, straw cloth, etc., the same irritability, polluted environment. With the gradual pr...
