As can be seen by combining example 2, comparative example 1 and comparative example 2 and combining Table 2, the light transmittance of the ice cone imitation product prepared by comparative example 2 reaches 60%, but is not close to that of the real ice cone prepared by comparative example 1, and contains more bubbles, while the polyether modified silicone oil is added in example 2, so that the number of bubbles in the ice cone imitation product is greatly reduced, the light transmittance is improved, and the light transmittance reaches 87%, and is closer to that of the real ice cone prepared by comparative example 1, therefore, the transparency of the ice cone imitation product is improved, and the ice cone imitation product similar to the real ice cone is prepared.

As can be seen by combining example 2, comparative example 1 and comparative example 6 with Table 2, the ice cone-like product prepared in comparative example 6 has many bubbles and a transmittance of 40% which is far from the transmittance of the real ice cone prepared in comparative example 1, and the defoaming treatment step is adopted in example 2, the number of bubbles in the prepared ice cone-like product is greatly reduced, so that the transmittance is improved, and the transmittance reaches 87% which is closer to the transmittance of the real ice cone prepared in comparative example 1, therefore, the transparency of the ice cone-like product is improved, and the ice cone-like product similar to the real ice cone is prepared.

By combining the example 2, the comparative example 1, the comparative example 2 and the comparative example 6 and combining the table 2, it can be seen that the step of adding the polyether modified silicone oil and the step of defoaming treatment in the example 2 exert a synergistic effect to obtain the best effect on reducing bubbles, and compared with the comparative example 6 in which the polyether modified silicone oil is added alone and the comparative example 2 in which the defoaming treatment is added alone, the light transmittance of the product prepared in the example 2 is closest to that of the ice cone, so that the step of adding the polyether modified silicone oil and the step of defoaming treatment exert a synergistic effect to improve the transparency of the ice cone-like product, and the ice cone-like product similar to the ice cone is prepared.

As can be seen by combining example 2, example 6 and comparative example 1 with Table 2, the use of styrene in example 6 to dilute the o-benzene type pre-accelerated unsaturated polyester resin reduced the number of bubbles in the article, no bubbles were seen in the ice-cone-like article obtained in example 6, and the light transmittance was 1.07 times that of the ice-cone-like article obtained in example 2 and was closer to that of the real ice cone obtained in comparative example 1, and therefore, the transparency of the ice-cone-like article was improved to obtain an ice-cone-like article similar to a real ice cone.

By combining the embodiment 6 and the embodiment 8 and combining the table 2, the ice-like cone product obtained by manufacturing the three layers of materials of the substrate, the highlight layer and the surface layer has the original light transmittance, and has better reflectivity at the highlight layer, when light passes through, reflected light can be generated, the loss of light is reduced, and the transparency of the ice-like cone product is improved.

The reason for the analysis may be: the white mica powder is adsorbed on the tetrapod-like zinc oxide whiskers and dispersed in the o-benzene type pre-accelerated unsaturated polyester resin, the o-benzene type pre-accelerated unsaturated polyester resin enables the tetrapod-like zinc oxide whiskers adsorbed with the white mica powder to be bonded on the surface of the matrix, and the tetrapod-like zinc oxide whiskers have a tendency of moving towards the interior of the matrix due to the fact that the matrix is in a state of not being completely cured, and bonding strength of the high-gloss layer film-forming liquid and the matrix is enhanced. The o-benzene type pre-accelerated unsaturated polyester resin forms a highlight layer after forming a film, when external light irradiates the surface of the product, the resin which is not dotted with the highlight layer is in a transparent state, and the light can penetrate through the resin, so that the product has transparent true ice texture under the irradiation of the light. The white mica powder exists at the position of the high light layer, light is reflected at the white mica powder, and the white mica powder is adsorbed on the tetrapod-like zinc oxide crystal whisker to form reflected light with different angles, so that the light loss is reduced, and the transparency of the ice-like cone product is improved.

It can be seen by combining example 8 and comparative example 3 and table 2 that the matte layer in the ice-like cone product prepared in comparative example 3 is made of varnish, the matte layer in the ice-like cone product prepared in example 8 is made of o-benzene type pre-accelerated unsaturated polyester resin, and the reflectance of the ice-like cone product prepared in example 8 is about twice that of the ice-like cone product prepared in comparative example 3, which shows that the tetrapod-like zinc oxide whiskers and muscovite powder are dispersed in the o-benzene type pre-accelerated unsaturated polyester resin and then bonded with the matrix to exert a synergistic effect, so that the better refraction performance can be shown, the light loss can be reduced, and the transparency of the ice-like cone product can be improved.

It can be seen from the combination of example 8 and comparative example 4 and the combination of table 2 that the ice-like cone product prepared in comparative example 4 has no tetrapod-like zinc oxide whiskers, so that the white mica powder is randomly dispersed in the o-benzene type pre-accelerated unsaturated polyester resin, although the ice-like cone product also has a certain refractive index, multi-angle reflected light cannot be generated under the irradiation of light, the reflectivity of the ice-like cone product prepared in example 8 is 2.4 times of the reflectivity of the ice-like cone product prepared in comparative example 4, and the effect that the tetrapod-like zinc oxide whiskers and the white mica powder play a synergistic effect to show better refraction performance, reduce light loss and improve the transparency of the ice-like cone product is achieved.

By combining example 8, comparative example 5 and table 2, it can be seen that the ice-cone-like product prepared in comparative example 5 has no surface layer, so that the surface of the ice-cone-like product is rough, the light transmittance of the ice-cone-like product is reduced, and the transparency of the ice-cone-like product prepared in comparative example 5 is lower than that of the ice-cone-like product prepared in example 8, thus reflecting the effect of the preparation method in example 8 on improving the transparency of the ice-cone-like product.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
