Novel environment-friendly urea-formaldehyde resin and preparation method thereof

The invention provides a novel environment-friendly urea-formaldehyde resin and a preparation method thereof. The novel environment-friendly urea-formaldehyde resin comprises the following components in percentage by weight: 28-72% of formaldehyde, 15-40% of urea, 8-16% of rock powder, 2-8% of white mineral oil, 2-5% of tea seed oil, 0.2-1% of formic acid and 0.5-1% of alkali. The preparation method comprises the following steps: weighing the raw materials according to the percentage by weight, adding the weighed formaldehyde and urea into a reaction kettle, starting a stirrer, performing uniform stirring, and performing cooling to room temperature after thermostatic reaction, thereby obtaining a primary urea-formaldehyde resin; adding the weighed rock powder into the primary urea-formaldehyde resin, and performing forming to obtain an environment-friendly urea-formaldehyde resin semifinished product; and adding the weighed white mineral oil, tea seed oil, formic acid and alkali into the urea-formaldehyde res
