Abstract

The invention discloses melamine resin capable of preventing finger prints as well as a preparation method and application of the melamine resin. The melamine resin capable of preventing finger printsis prepared by the following preparation method: 1) adding emulsion extinction resin, a formaldehyde solution, polyethylene glycol, melamine and water into a reaction kettle, and adjusting the pH value of the obtained reaction solution to 8.8-9.2; 2) heating the reaction solution, and adding caprolactam into the reaction solution when the reaction solution becomes clear; 3) carrying out heat preservation reaction, conducting sampling and testing a fog point end point, and stopping heating; and 4) adjusting the pH value to 8.0-8.7, and conducting discharging and standing to obtain the melamineresin capable of preventing finger prints. The invention also discloses application of the melamine resin for preventing finger prints. The melamine resin disclosed by the invention has a function ofpreventing finger prints, and the influence of fingerprints can be eliminated when the melamine resin is applied to decorative adhesive film paper, so that a decorative material keeps an attractive effect.

Description

technical field [0001] The invention relates to a melamine resin, in particular to an anti-fingerprint melamine resin and its preparation method and application. Background technique [0002] With the improvement of people's living standards and aesthetics, the consumption trend is also constantly changing. Many consumers require fashionable, personalized and magnificent home decoration materials, as well as environmentally friendly, clean, safe and higher-quality materials. More than 80% of household products on the market are decorative wood-based panel materials. Among wood-based panel surface decoration materials, decorative film paper is the largest component of the world's total consumption of decorative materials. Decorative film paper is made of special titanium powder paper after printing, impregnation and pressing. Using decorative adhesive film paper on the wood-based panel for surface decoration can cover up and eliminate various defects on the surface of the w...
