Problems solved by technology

This type of resin is generally composed of matrix resin, optical additives, processing aids and other raw materials, but generally can only show the color sense of jade, and cannot imitate the hazy feeling of jade.
[0004] Moreover, among the optical additives, the cost of the organic optical additives is relatively high, and the dispersion of the inorganic optical additives is poor, so the optical effect formed is unsatisfactory.

Abstract

The invention relates to the technical field of resin composites, in particular to a jade-like composite and a preparation method thereof. The jade-like composite comprises matrix resin, light diffusion microspheres, antioxidant, light stabilizer, ultraviolet light absorber, toner and the like. The composite disclosed by the invention presents an evenly dispersed natural jade appearance, and in addition, nanometer inorganic light diffusant enables the jade-like composite to own the advantages of high haze, high refractive index and the like due to the size effect of the nanometer inorganic light diffusant. In addition, the jade-like composite can serve as the interlayer of double-layer glass, so that the jade effect has third dimension, the jade composite can be favorably protected, and the possibility of the physical damage or the chemical oxidization of the jade composite is reduced.

Description

technical field [0001] The invention relates to the technical field of resin compositions, in particular to an imitation jade composition and a preparation method thereof. Background technique [0002] The ancients wore jade to show the virtue of a gentleman, and modern people also regard it as a symbol of increasing luck and social status. The Chinese love jade is always the same. Looking at today's domestic market, all kinds of jade are all over the market, and the price ranges from a few yuan for small ornaments to tens of millions of ancient jade. [0003] With the continuous development of technology, aesthetic resins can achieve a variety of effects, such as spray-painted silver, electroplated silver, pearlescent red, silvery black, and starry sky. In addition, aesthetic resins that imitate natural effects are also constantly developing, imitating jade Advanced aesthetic resins are also being developed continuously. This type of resin is generally composed of matrix ...
