Problems solved by technology

[0004] However, the compatibility of SBID powder with polymer products is usually poor, and it is easy to affect the impact strength of polymer products. In order to facilitate the mixing of SBID powder in the polymer matrix, it is usually necessary to process It carries out surface pretreatment. The conventional surface pretreatment method is to use silicon, aluminum, boron, etc. for coating treatment by liquid phase method. This preparation method is to first stir and mix the required inorganic powder and surface treatment agent, Add solvent and stir, and then repeatedly dilute and grind to make various powders mix evenly and finely, and then remove moisture from the powder by high-temperature sintering, and then break up and agglomerate to become IT industry polymer line products The addition of main raw materials
[0005] The existing SBID powder surface treatment method has the following disadvantages: 1. The SBID powder is prone to agglomeration in the solution, which affects the final coating effect; 2. The coated powder is also prone to exist during the drying process. Agglomeration, even subsequent grinding and other treatments are required, which not only easily introduces impurity ions, but also may damage the coating layer, affecting the compatibility of SBID powder and polymer matrix

Abstract

The invention relates to the non-metal material surface metallization field and, in particular, the invention discloses an inorganic powder surface treatment method and chemical plating activating agents and a polymer product and a polymer product surface selective metallization method. The inorganic powder surface treatment method comprises the following steps: (s1) inorganic powder is mixed with surface treatment agent dissolved in dispersant to form a spray slurry; (s2) the spray slurry is added into a spray drying device, atomized by an atomizer to form fog drops, and the fog drops are brought into contact with the surface of a heating part arranged inside the spray drying device to be dried, so as to obtain the surface-treated inorganic powder. According to the method, the fog drops formed by atomizing the spray slurry are brought into contact with the surface of the heating part to rapidly evaporate the dispersant in the spray slurry, so that the surface treatment agent can be deposited on the surface of the inorganic powder to form a cladding layer, thereby improving the compatibility between the inorganic powder and the polymer matrix, and optimizing the anti-impact strength of the polymer product.
