Embodiment 1

[0023] Take a container, pour 50g of potassium silicate solution and 100g of sodium silicate solution into the container respectively, mix and heat at about 70°C, then slowly add 100g of silicon acrylic emulsion into the container, and keep stirring with a mixer, dropwise After completion, the temperature of the system was lowered to room temperature, and then 25g of isopropyl tris(dioctyl phosphate acyloxy) titanate was added to the container, and the stirring speed was increased, then 200g of ultrafine zinc powder was added, and finally 25g of zinc powder was added. Dilute phosphoric acid, that is, a zinc-rich coating added with isopropyl tris(dioctyl phosphate acyloxy) titanate.

Embodiment 2

[0025] Take a container, pour 75g of potassium silicate solution and 75g of sodium silicate solution into the container respectively, mix and heat at about 75°C, then slowly add 75g of silicon acrylic emulsion into the container, and keep stirring with a mixer, dropwise After completion, the temperature of the system was lowered to room temperature, and then 15g of isopropyl tris(dioctyl phosphate acyloxy) titanate was added to the container, and the stirring speed was increased, then 250g of ultrafine zinc powder was added, and finally 10g of zinc powder was added. Dilute phosphoric acid, that is, a zinc-rich coating added with isopropyl tris(dioctyl phosphate acyloxy) titanate.

Embodiment 3

[0027] Take a container, pour 100g of potassium silicate solution and 100g of sodium silicate solution into the container respectively, heat it at about 80°C after mixing, then slowly add 150g of silicon-acrylic emulsion into the container, and keep stirring with a mixer, dropwise After the completion, the temperature of the system is lowered to room temperature, and then 30g of isopropyl tris (dioctyl phosphate acyloxy) titanate is added to the container, and the stirring speed is increased, then 600g of ultrafine zinc powder is added, and finally 20g of zinc powder is added. Dilute phosphoric acid, that is, a zinc-rich coating added with isopropyl tris(dioctyl phosphate acyloxy) titanate.

Abstract

The invention discloses zinc-rich paint with addition of isopropyl tri (dioctyl phosphate acyloxy) titanate and a preparation method thereof. According to the zinc-rich paint with the addition of the isopropyl tri (dioctyl phosphate acyloxy) titanate, through the addition of an isopropyl tri (dioctyl phosphate acyloxy) titanate coupling agent, not only is the adhesive force of the paint improved greatly, but also the effects of preventing sedimentation and improving the mechanical strength of the composite material can be effectively achieved.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to a zinc-rich coating added with a titanate coupling agent, and belongs to the field of coatings. Background technique [0002] With the development of the metal industry, the use of metal is becoming more and more common. Metal materials are used everywhere in life, such as the automobile industry, manufacturing industry, construction industry, transportation industry, and metal materials are used in all walks of life in life. Among metal materials, steel is the most widely used. In 2014, the global crude steel output reached 1.662 billion tons, a year-on-year increase of 1.2%. Among them, China's crude steel output reached 822.7 million tons, and steel is mainly used in structural materials, large buildings and large machinery. When steel is used, it is easy to corrode. When it corrodes, a chemical or electrochemical multiphase reaction occurs on the interface of the metal, which tur...
