Embodiment 1

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

[0036] (1) Preparation of modified glass beads

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

[0038] The mixed glass microspheres obtained by mixing solid glass microspheres and hollow glass microspheres with particle diameters of 10.0 μm are 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) and hydrofluoric acid (HF) in a mixture of coarsening, washing, tin chloride (SnCl 2 ) and hydrochloric acid (HCl) in a mixture of sensitization, water washing, ammonia solution containing silver nitrate (AgNO 3 +NH 3 ·H 2 O) in the activation step for processing.

[0039] After the surface pretreatment of the glass beads, the chemical activity of the surface is improved, and then the metal aluminum film is coated on the pretreated glass beads by means of che...

Embodiment 2 to Embodiment 6

[0055] According to the components specified in Table 1, the weight ratio of the modified glass microspheres 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 situation that each component content of table 1 embodiment 4 is constant, only change the weight ratio of a class of glass microspheres and the second class of glass microspheres, other steps repeat the preparation method in embodiment 4, listed in table 2 corresponding test results.

[0066] Table 2 Effects of the contents of Class I glass microspheres and Class II glass microspheres on yellowing resistance and easy-to-clean performance

[0067]

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

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...
