Problems solved by technology

There are many kinds of paints and coatings on the market, but most of these paints and coatings only have protective and decorative functions, and their functions are relatively single.
Along with the increase of people to the function demand of paint coating, especially in order to prevent bacterial reproduction for a long time, existing paint coating can't satisfy people's needs, therefore, need a kind of paint coating long-acting antibacterial additive so as to be able to produce Paint coatings with long-lasting antibacterial effect

preparation example Construction

[0025] The preparation technology of long-acting antibacterial additive of paint coating comprises the following steps:

[0026] S1. Raw materials and pretreatment:

[0027] S11, preparation of buffer solution:

[0028] Prepare trehalose at a concentration of 1-4g / 100mL and maltodextrin at a concentration of 5-15g / 100mL;

[0029] S12, preparation of a solution containing platinum ions:

[0030] Add hexachloroplatinate into the buffer solution, stir at a low speed, and prepare a solution A with a platinum ion concentration (hexachloroplatinate) of 0.2-0.7 mol / L;

[0031] S13. Preparation of reducing solution: Dissolve citric acid in water to obtain solution B; wherein, the concentration of citric acid is 10wt%-25wt%;

[0032] S2. Slowly add solution B to solution A under ultrasonic irradiation and medium-speed stirring, and stir with an electric stirrer for 15 minutes; then add part of the buffer solution, and make the molar mass of trehalose and maltodextrin in the mixed so...

Abstract

The invention discloses a paint coating long-acting antibacterial additive. The paint coating long-acting antibacterial additive is prepared from the following components in percentage by weight: 0.15percent to 0.35 percent of citric acid, 0.002 percent to 0.003 percent of Pt.C7H15N3 and 0.001 percent to 0.0015 percent of malic acid. The molecular weight of Pt.C7H15N3 is 336.05. The paint coatinglong-acting antibacterial additive disclosed by the invention contains the nano platinum sterilizing component and has long-acting antibacterial capability.

Description

technical field [0001] The invention relates to the field of preparation of nano-platinum particles, in particular to long-acting antibacterial additives for paints and coatings and a preparation process thereof. Background technique [0002] Paint is one of the indispensable materials in the process of home decoration. There are various kinds of paint coatings on the market now, but these paint coating great majority just have protection, decoration effect, and function is more single. Along with the increase of people to the function demand of paint coating, especially in order to prevent bacterial reproduction for a long time, existing paint coating can't satisfy people's needs, therefore, need a kind of paint coating long-acting antibacterial additive so as to be able to produce Paint coating with long-lasting antibacterial effect. Contents of the invention [0003] The object of the invention is to provide long-acting antibacterial additives for paints and coatings ...
