Abstract

The invention relates to the technical field of advertisement word manufacturing, in particular to anti-yellowing photocuring liquid acrylic glue and a preparation method of the acrylic glue. The acrylic glue comprises the following raw materials in parts by weight: 15-25 parts of PMMA (polymethyl methacrylate) resin, 40-60 parts of methyl methacrylate, 25-35 parts of butyl methacrylate, 0.3-0.7 part of light homogenizer and 0.5-1.5 parts of photoinitiator. The acrylic glue resists yellowing and ageing, is low in viscosity and good in leveling property and defoaming performance, can be cured at room temperature or moderate temperature and is moderate in curing velocity; a cured product is better in toughness and flexibility, good in transparency, smooth and bright in surface strong in adhesion and free from bubbles; and the cured product further has good solvent resistance and excellent moisture resistance and water resistance.

Description

technical field [0001] The invention relates to the technical field of advertising letter making, in particular to a light-curing anti-yellowing liquid acrylic glue and a preparation method thereof. Background technique [0002] Resin cast luminous characters, because the color and light transmittance of the resin can be freely adjusted, make up for the shortcomings of acrylic plate luminous characters in single color selection and non-adjustable light transmittance, and become the new darling of the advertising sign industry. The structure of the common three-dimensional resin casting luminous nameplates on the market includes metal letter shells (made of iron sheet paint, stainless steel, aluminum and other metals), LED light sources and transparent glue injection layers. [0003] The existing transparent glue injection layer is prone to yellowing with the prolongation of use time, and has aged under the use environment of wind and rain, and has a short service life. Con...
