Embodiment 1

[0035] The preparation of the anti-yellowing product comprises the following steps:

[0036] (1) Preparation of modified glass beads

[0037] 1) Preparation of a class of glass microbeads

[0038] The mixed glass microbeads obtained by mixing solid glass microbeads and hollow glass microbeads with particle diameters of both 10.0 μm were subjected to surface pretreatment. Among them, the solid glass microspheres account for 50.0% of the mixed glass microspheres, and the hollow glass microspheres account for 50.0%. 4 F) coarsening, washing with water, tin chloride (SnCl) in the mixed solution of hydrofluoric acid (HF) 2 ) and hydrochloric acid (HCl) mixed solution sensitized, washed with water, ammonia solution containing silver nitrate (AgNO 3 +NH 3 ·H 2 O) in the activation step for treatment.

[0039] The glass microspheres after surface pretreatment have improved the chemical activity of their surface, and then the pretreated glass microspheres are coated with metal al...

Embodiment 2 to Embodiment 6

[0055] According to the components specified in Table 1, the weight ratio of the modified glass beads was appropriately adjusted, and the preparation method in Example 1 was repeated. Table 1 lists the corresponding test results.

Embodiment 7-13

[0065] Under the condition that the content of each component in Example 4 in Table 1 is unchanged, only the weight ratio of the first-class glass microbeads and the second-class glass microbeads is changed, and the preparation method in Example 4 is repeated for other steps. Table 2 lists corresponding test results.

[0066] Table 2 Effects of content of first-class glass microbeads and second-class glass microbeads on yellowing resistance and easy-to-clean performance

[0067]

[0068] It can be seen that within a certain range, the more content of the first-class glass microbeads, the better the yellowing resistance, and the more the content of the second-class glass microbeads, the better the easy-to-clean performance. However, considering the acceptable range of yellowing resistance and easy-to-clean performance of the product, the content of Class I glass microbeads is 70%-85%, the content of Class II glass microbeads is 15%-30%, and the content of Class I glass micro...

Abstract

The invention discloses a modified glass microsphere, a preparation method thereof and a method for preparing composite resin products using the same. Modified glass microspheres include Type I glass microspheres and Type II glass microspheres. The surface of Type I glass microspheres is coated with discontinuous metal layers and UV absorbers. The surface of Type II glass microspheres is coated with hydrophobic materials, and The coverage rate of the layer on the surface of a class of glass microspheres is 45.0-85.0%, and the above-mentioned modified glass microspheres are added to the components of ordinary anti-yellowing products to improve the anti-yellowing performance and mechanical properties of the products.

Description

technical field [0001] The invention relates to the technical field of yellowing resistance modification of polypropylene resin, in particular to a modified glass microbead, a preparation method thereof, and a method for preparing composite resin products with the same. Background technique [0002] Most of the existing squat toilet water tanks are made of polypropylene resin (hereinafter referred to as PP resin) material. First of all, PP resin products are prone to yellowing during use. Therefore, it is incompatible with the white tiles and white sanitary ceramics in the surrounding environment, which affects the overall aesthetics of the bathroom. Secondly, after yellowing and aging of PP resin, it is easy to cause chalking, which makes the surface of the water tank of the squatting toilet easy to become dirty and difficult to clean due to the roughness after long-term use, which seriously affects the strength performance of the product and the user. user experience. In...
