Abstract

The invention relates to an urushiol resin for three-dimensional printing and a preparation method thereof. The preparation method comprises the following steps: mixing the urushiol resin or an urushiol derivative and a diene monomer according to a mass ratio of 100:1-100:50, adding a photoinitiator which is 1% of the total mass of the both parties, and uniformly stirring, to obtain the urushiol resin for the three-dimensional printing. The urushiol resin for the three-dimensional printing is capable of, under the irradiation of ultraviolet light, and through controlling the types and dosagesof the diene monomer, changing the basic physical properties of the resin and the content of a carbon-carbon double bond (C=C), namely fine-adjusting the using performance of the resin through the types of the diene monomer, and realizing the controllable free radical cross-linking polymerization of the urushiol resin through controlling the content of a free radical. The urushiol resin for the three-dimensional printing is suitable for multiple photocuring three-dimensional printing technologies, and suitable for the field of manufacturing lacquerware artware, such as a bodiless lacquer.

Description

technical field

[0001] The invention belongs to the field of three-dimensional printing resins, and in particular relates to an urushiol resin for three-dimensional printing and a preparation method thereof. Background technique

[0002] Lacquerware is exquisite in craftsmanship and rich in culture, especially in modern bodiless lacquerware, which is not only a treasure of Chinese lacquer art. However, with the change of the times, the shortcomings of lacquerware, such as complicated craftsmanship and high price, have become prominent, the market demand has been greatly reduced, and the industrial development has encountered a bottleneck.

[0003] Natural lacquer is the main raw material of Chinese lacquerware. Urushiol, the main component of lacquer, is a mixture of catechol derivatives with several unsaturated branched chains. The curing of raw lacquer (crosslinking of urushiol) has different mechanisms and properties due to different conditions. In the traditional proc...
