Abstract

The invention relates to a modified PC hardening liquid formula and a preparation method thereof. The formula comprises 40-60 parts of urethane acrylate, 12-18 parts of an ester solvent, 8-12 parts ofan alcohol solvent, 4-6 parts of a photosensitizer and 1.6-2.4 parts of a leveling agent. The method comprises the following steps: putting urethane acrylate into a container; adding a photosensitizer; adding an ester solvent, and soaking; adding an alcohol solvent, and stirring by using a high-speed stirrer; and finally, adding a proper amount of leveling agent, stirring, standing and packaging.The formula has the beneficial effects that the effects of scratch resistance, dirt resistance, fingerprint resistance and the like are improved; meanwhile, the light transmittance of the base material is also integrally improved and the energy loss and the environmental pollution are reduced so that the energy-saving and environment-friendly effects of the base material are achieved; use is convenient, cost is low, the effect is good, and wide application and popularization are facilitated; the raw materials are scientific and environment-friendly, the production process is simple and the product is easy to process.

Description

technical field [0001] The invention relates to the technical field of hardening liquid production, in particular to a modified PC hardening liquid formula and a preparation method thereof. Background technique [0002] Hardening fluid is used in resin, plastic, adhesive and coating industry, also known as UV hardening fluid. The hardening solution is composed of oligomers, monomers, and photoinitiators, and does not contain any organic solvents, so it is easy to use. The hardening solution can be directly or diluted and coated on various substrates, such as PET, TAC, PC, PMMA. After coating, it can effectively improve the wear resistance, scratch resistance, chemical corrosion resistance and other characteristics of the substrate, and effectively improve the protection performance of the substrate. However, the existing hardening solutions are not very outstanding in improving the hardness of the substrate, scratch resistance, antifouling and fingerprint resistance, and n...
