Embodiment 1

[0011] Take by weighing 2600 grams of aminoacrylic resin, 80 grams of 1-hydroxycyclohexyl phenylacetone, 1800 grams of 2-hydroxyacrylic resin, 60 grams of 1173 (alpha-hydroxyisobutyrophenone) and 460 grams of epoxy acrylic resin, put into reaction The kettle is refluxed and stirred, heated to 140°C for 10 hours, cooled to 50°C and then discharged to obtain all-weather bronzing UV varnish.

[0012] Treat the surface of the polyethylene plastic hose with flame or corona, apply the UV varnish prepared in this example evenly on the surface of the hose through a glazing device, and then cure it with a UV light box. The thickness of the cured UV varnish is 3 Micron. Stamp the polished hose on a hot stamping machine as a standard reference sample. Store the unstamped varnish tubes in a sealed seal, take out 100 tubes in the following time periods, and do a bronzing test for comparison, and the following results are obtained:

[0013] 1. After 7 days, it can be bronzing;

[0014] 2...

Embodiment 2

[0019] Take by weighing 2000 grams of aminoacrylic resin, 50 grams of 1-hydroxycyclohexyl phenylacetone, 2000 grams of 2-hydroxyacrylic resin, 100 grams of 1173 (alpha-hydroxyisobutyrophenone) and 850 grams of epoxy acrylic resin, put into reaction The kettle is refluxed and stirred, heated to 150°C for 8 hours, cooled to 50°C and then discharged to obtain all-weather bronzing UV varnish.

[0020] Treat the surface of the polyethylene plastic hose with flame or corona, apply the UV varnish prepared in this example evenly on the surface of the hose through a glazing device, and then cure it with a UV light box. The thickness of the cured varnish is 5 microns . Then gilt the polished hose on a gilding machine as a standard reference sample. Store the non-bronzing glazing hose in a sealed seal, take out 100 tubes at 7 days, 30 days, 90 days, 180 days, and 360 days respectively, and do a bronzing test for comparison. Bronzing on UV varnish.

Embodiment 3

[0022] Take by weighing 3000 grams of aminoacrylic resin, 50 grams of 1-hydroxycyclohexyl phenylacetone, 1500 grams of 2-hydroxyacrylic resin, 50 grams of 1173 (α-hydroxyisobutyrophenone) and 400 grams of epoxy acrylic resin, and put them into reaction The kettle was refluxed and stirred, heated to 145°C for 9 hours, cooled to 50°C and then discharged to obtain all-weather bronzing UV varnish.

Abstract

The invention relates to all-weather UV gloss oil capable of bronzing. Raw material consists of the following compositions in percentage by weight: 40 to 60 percent of amino-acrylics, 1 to 2 percent of 1-hydroxy cyclohexyl phenylacetone, 30 to 40 percent of 2-hydroxy acrylics, 1 to 2 percent of A-hydroxy isobutyrophenone, 8 to 18 percent of epoxy acrylic resin. The UV gloss oil has the advantage of long-term effect, is not limited by the light-curing condition in use and can be gilded after being solidified and placed for a long time.

Description

technical field [0001] The invention relates to a bronzing UV varnish for decorating the surface of plastic products. Background technique [0002] UV varnish that can be bronzed can be bronzed UV curable varnish is often used to decorate the surface of plastic hoses for cosmetic packaging. Existing bronzing UV varnishes are short-acting, and must be bronzed immediately after glazing, and after multiple UV curings, cannot be bronzed on it again, or can no longer be bronzed when placed for more than one day after photocuring. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the existing bronzing UV varnish, and to provide a long-lasting, all-weather bronzing UV varnish that can still meet the bronzing requirements no matter how long it is placed after multiple UV curing . [0004] The all-weather bronzing UV varnish of the present invention, its raw material is made up of the following components,...
