Example Embodiment

[0034] Example 1

[0035] The preparation of yellowing resistant products includes the following steps:

[0036] (1) Preparation of modified glass beads

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

[0038] The mixed glass beads obtained by mixing solid glass beads with a particle size of 10.0 μm and hollow glass beads are subjected to surface pretreatment. Among the mixed glass beads, solid glass beads accounted for 50.0%, and hollow glass beads accounted for 50.0%. The surface pretreatment specifically includes alkaline washing (NaOH), water washing, and ammonia fluoride (NH 4 F) and hydrofluoric acid (HF) in the mixture of coarsening, washing, tin chloride (SnCl 2 ) And hydrochloric acid (HCl) mixed solution sensitized, washed with water, silver nitrate-containing ammonia solution (AgNO 3 +NH 3 ·H 2 O) The activation step is processed.

[0039] The surface pretreatment of the glass beads enhances the chemical activity of the surface, and then the pretreated glass beads are coat...

Example

[0054] Example 2 to Example 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.

Example Embodiment

[0064] Example 7-13

[0065] Under the condition that the content of each component of Example 4 in Table 1 remains unchanged, only the weight ratio of the first type of glass beads to the second type of glass beads is changed, and the preparation method in Example 4 is repeated for the other steps. Table 2 lists The corresponding test result.

[0066] Table 2 The influence of the content of the first class glass beads and the second class glass beads on the yellowing resistance and easy-to-clean performance

[0067]

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

Abstract

The invention discloses a modified glass microsphere and a preparation method thereof and a method for preparing a composite resin product by using the modified glass microsphere. The modified glass microsphere includes a first class glass microsphere and a second class glass microsphere, a discontinuous metal layer and an ultraviolet absorbent wrap the surface of the first class glass microsphere, a hydrophobic material wraps the surface of the second class glass microphere, the coverage rate of the metal layer on the surface of the first glass microsphere is 45.0%-85.0%, and the modified glass microbead is added into the component of a common anti-yellowing product to improve the anti-yellowing property and the mechanical property of the product.

Description

technical field [0001] The invention relates to the technical field of anti-yellowing modification of polypropylene resin, in particular to a modified glass microsphere, a preparation method thereof and a method for preparing composite resin products using the same. Background technique [0002] Existing squatting pan water tank mostly adopts polypropylene resin (hereinafter referred to as PP resin) material to make. First of all, PP resin products tend to turn yellow during use. Therefore, they are inconsistent with white tiles and white sanitary ceramics in the surrounding environment, which affects the aesthetics of the overall bathroom space. Secondly, after yellowing and aging, PP resin is also prone to powdering, which makes the surface of the squatting toilet tank become rough after a long period of use, and it is easy to become dirty and difficult to clean, which seriously affects the strength and performance of the product and the user. use experience. In response...
